Thirst for dividends and financial illiteracy

I simply had to use the word "thirsty" today for this reason.

My country restarted the capitalist system over 3 decades ago, and it's had centuries of experience with it before 1948. Western countries (in the Cold War sense) have lived in the uninterrupted capitalism for centuries. Nevertheless, it seems to me that only a tiny fraction of my nation – and Western nations – understands totally basic concepts of capitalism such as "the rational reasoning needed to figure out how much you should pay for a stock".



OK, one extreme level of this financial illiteracy is the people's "investment" in stuff like the Bitcoin or Tesla, things that obviously don't have the intrinsic value matching the price – they have no chance to repay the invested money. The people buying into these bubbles resemble a cult. They probably realize that the Bitcoin or the Tesla stock can never pay those $5,000 or $60 per stock in dividends which would justify the valuations. And they don't seem to care because they apparently think that just like sex according to the hardcore feminists, the price is a purely social construct. These "investors" don't have any method to estimate the fair fundamental value. All of them are "momentum traders" – i.e. bad investors – and growing and bursting bubbles is the only thing they can achieve.

EO: Covid-19 tests are sterilized by a major carcinogen

I don't really believe that any of the widespread tests or vaccines are filling the victims with chips or some truly novel timebombs for their health. But I have always found it wise to be worried about carcinogens in various unusual health gadgets.

And a video I just received has explained that the tampons in the Covid-19 tests are labeled "SterileEO". It means sterilized – stripped of the bacteria – using ethylene oxide (a method that has been used for medical supplies for years before Covid-19, of course). Many people that the dude in the video knows have died of things like brain hemorrhage and other things.



EO is isomeric with acetaldehyde and with vinyl alcohol.

"Ethylene oxide itself is a very hazardous substance. At room temperature it is a flammable, carcinogenic, mutagenic, irritating, and anaesthetic gas," Wikipedia adds.

Pump and dump, manipulation

Wizard asked how did I reckon before Elon Musk is sent to jail. Well, I got already used to the fact that increasingly stunning examples of market manipulation are tolerated and I believe that it will get even worse – but it will stop at one future sunny day, anyway.



A comparison of BIG 5 electric SUVs released 2 days ago. Regardless of the price, Škoda Enyaq beats others in pretty much every respect, especially by its range which renders competitors obsolete. On top of that, it is 30% cheaper. Tesla Model Y may at most match the Enyaq but the price is 50% higher than the Enyaq, too.

In March, I discussed fake growth stocks and investments that weren't real investments, like the Cathie Wood ARK Innovation ETF Fund. It is a fund where the financially illiterate "guru" picks the "best" stocks – in particular, stocks of nearly worthless companies that are overpriced by a factor of 10+ and by promoting them (she has useful idiot friends in the media), she makes them overpriced by a factor of 100+ if not 1000+. By growing these bubbles around nearly worthless companies, she has been reporting impressive yields.

Manipulators like that often buy before others, and sell before others, and that is called the pump and dump securities fraud. Well, there are signs that she is forgetting to sell. If you click at the previous paragraph, you will see that the ARKK fund's price went from the peak $159.70 to the current $99.48, a 38% drop in 3 months. Compare it with the general stock indices that are at most 2% below the all time highs and even Nasdaq that is some 7-8% below the all time highs. Has the bubble burst?

European energy prices will go to the Moon

Notoriously enough, Austria organized its nuclear energy referendum in 1978. 50.5% voted against the Zwentendorf nuclear power plant plans and Austria became a hysterically anti-nuclear country, a fact that has often complicated the life of Czechs whose majority loves Austrians. This was an example of a referendum that should have been rigged by the sane people. The tiny edge of the Luddites has had far-reaching, long-term consequences.



Isar Zwo in Bavaria which we visited (as students) in 1992.

Germany remained nuclear (although not as much as France which makes 70% of its energy from the nuclei, and it used to be 80%) up to this nation's hysterical reaction to the 2011 tsunami-inspired glitches in Fukushima. Germans decided to obediently agree with their leaders' decision to ban nuclear physics in Germany. No \({\rm MeV}\)s allowed there; applied nuclear physics was rebranded to just another pseudoscience promoted by the groups that the Germans have the "right" to bully. Well, the moment when the last power plants should be stopped is coming closer.

Mathematics, quantitative attitude distinguishes the human civilization from animals

People have replaced Nature's random "trial and error" method with something a bit more pre-planned, and calculations are needed for those civilized plans



Mr Huml (from the Ice Age) was explaining to Mr Mach that it was a cold age and people had a lot of cold. They often caught a mammoth and ate it with a dill+cream sauce.

In the text about the limits of the ancient Greek "science" and "technology", a commenter named giant claimed to argue that one didn't need any science in the modern sense – founded by Galileo – because one may mention a counterexample, namely bronze. He added:

Somehow people figured out how to make an alloy, without understanding atoms, crystalline structure, temperatures, no chemistry at all.
Cute. Indeed, people could make bronze without any of these sciences. But that's because "making bronze" isn't scientifically difficult – surely not to an extent that would be comparable to the science that is needed to build and/or optimize a steam engine (with a gearbox).

What is bronze? It's an alloy composed of (mostly) copper and also some other metal, typically tin (12-12.5%). However, the percentage is this precise because the Wikipedia editors added this number long after the Bronze Age. ;-) That's a percentage where the alloy holds together. In the Bronze Age, not only the folks didn't know about the 12-12.5% interval. In fact, the tin was often not tin at all. Bronze may also be a copper alloy with aluminium, manganese, nickel or zinc; or arsenic, phosphorus, or silicon. And these other materials were indeed mixed with copper during the Bronze Age (arsenic was actually common there).

Lawrence Krauss vs Biden's woke science administrator

...and the National Academy of Sciences...



A picture from the article we discuss. You may click to have an idea about the woke people's discussions on Twitter.

Tom W. has sent me a link to this essay by cosmologist Lawrence Krauss (a noted atheist activist and one of the people who saw the light about the looming discovery of the cosmological constant before it was seen in the 1990s, among other things) in the Wall Street Journal:

The New Scientific Method: Identity Politics (the paywall is just partial)
While Krauss has looked like another left-wing scientist-activist for decades and the WSJ is a RINO daily, I think, this almost sounds like a sane person's or rightwinger's alarm. Krauss points out that much of the funding ($7 billion) for physical sciences comes from the Department of Energy. He complains both about the Biden Administration and the National Academy of Sciences because they seem to be in the process of politicizing and ruining science – I would add, along the lines of the Aryan Physics in Nazi Germany and Lysenkoism in the Soviet Union. Unlike Krauss' insights about the cosmological constant, this observation didn't exactly come "in time"! ;-)

California plans to torture kids who are great in maths

First, The Rebel News, the most important Canadian independent news agency, was banned at PayPal with no stated legitimate reason. At least, they can withdraw the remaining funds. But they couldn't even use PayPal to buy food – they need to investigate whether maple leafs are edible, among other things.

The far left terrorists who are behind this terrorist act need to be caught and executed (The Rebel News plan a lawsuit but sadly, the death penalty was abolished in 1976 in Canada) and if people like co-founders of PayPal Musk and Thiel fail to do something against similar terror perpetrated by their corporate child, they need to spend the rest of their lives in jail, too. I am so unbelievably disappointed by all these men.



Meanwhile, mathematically gifted kids are the main enemy in California's government agencies.

CALIFORNIA UNVEILS NEW WOKE MATH PROGRAM, ENCOURAGING TEACHERS TO PUNISH GOOD STUDENTS BY HOLDING THEM BACK
A super-idiotic revolutionary manifesto that has hundreds of pages (maybe we are talking about this truly juicy anti-white racist 83-page rant, thanks, Bill, maybe there is another one) was released by the California Health Department and is apparently being embraced by the California's Department of Education (but the stuff hasn't been completely approved yet). Words are no longer enough, the authors claim. We must act and erase the inequality by holding back all kids who are better in mathematics than others. All instruction must proceed according to the weakest student in the class because the far left sick animals "reject ideas of natural gifts and talents". In that state and others, it's not only tolerated but fashionable to "reject" even the most obvious facts about the real world. According to the plan, the smart kids must be made unable to work on their mathematical talent, at least up to their 18th birthday. Wow.

Wormholes in general phase spaces



Herman Verlinde (Princeton) has released two new papers about one topic

Wormholes in Quantum Mechanics
Deconstructing the Wormhole: Factorization, Entanglement and Decoherence
He has studied general enough quantum mechanical systems – including simple enough ones such as a coupled harmonic oscillator – using the path integral. The path integral sums over all histories which are curves on the phase space (OK, he picks the phase space path integral; I don't exactly know why).

100 marbles and a doubling, a puzzle

One hundred marbles numbered 1 through 100 are in a bowl. The marbles are drawn one at a time without replacement. How many marbles must be drawn to be sure that one of the selected numbers is exactly twice as large as another selected number?
I received this problem via WhatsApp. If someone has given a home office problem to her students and they're cheating, then I am sorry but this remote learning is guaranteed to lead to a similar cheating and it's not my fault (and I have fought against the Covid-19 hysteria, lockdowns, home offices, and shutdowns as much as I could). Moreover, you don't know whether my solution is right.



Divide the marbles (numbers 1-100) to the smallest classes in which the potential collision (of a number with its double) may occur. Each class contains all the numbers\[ \{ k\cdot 2^M, \quad M\in\ZZ \} \] for some \(k\in \ZZ\), \(1\leq k\leq 100\). So one of the classes is \(\{1,2,4,8,16,32,64\}\), another class is \(\{3,6,12,24,48,96\}\), and so on. If you want to pick a maximum number of marbles so that the "collision with a doubled value" doesn't occur, these classes may be treated independently.

Reorganizing a 4D S-matrix within a celestial CFT

For a couple of years, Andy Strominger and his so far lesser but not last collaborators have been immensely excited about the celestial sphere.



It's not hard to see why. As you can see, the celestial sphere (in the sky) is blue and has pretty stars in it.

Strominger et al. have studied the encoding of black hole information as seen on that sphere, scattering, hair, new conservation laws, and other related things. Note that if you imagine that we live in a 3+1-dimensional spacetime for a while, what we see at night (at one moment) is a two-sphere, \(S^2\), of possible directions. Each point on this \(S^2\) is actually a line in the 4D Minkowski space which goes to infinity. That's why there is no natural finite "length scale" defined on this \(S^2\). However, you may measure angles. After all, this \(S^2\) is conformally equivalent to a complex plane and the angle-preserving, conformal \(SL(2,\CC)\) transformations of this plane (or sphere) are equivalent to the \(SO(3,1)\) Lorentz group that transforms the Minkowski space.

James Bond 007 goes from Prague to Moscow

Today, Czechia is shocked or amused by a new scandal. As you must have heard, the Czech intelligence services have claimed that it was very likely that a 2014 ammo depot blast in Eastern Czechia (in Vrbětice) was caused by Russian agents – in fact, by the same Petrov and Bashirov who have also allegedly prepared novichok for Mr Skripal later, in 2018. The accusations have led to the expulsion of Russian diplomats from Prague and the reciprocal expulsion of Czech diplomats from Moscow, aside from related new hostilities between countries whose relationships were decent in recent years.

However, SeznamZpravy.cz (DirectoryNews.cz), a news server connected to Seznam.cz, a Google-killing Czech search engine, has published an incredible twist hours ago. Mr Janek Kroupa and Ms Kristina Ciroková are signed under the report. While I consider SeznamZpravy.cz to be one of the neo-Marxist cesspools of the Czech journalism (fortunately they are a minority here, but not a small minority), Janek Kroupa is a highly nontrivial investigative journalist. I am pretty sure that it is fair to count him among the top 5 active investigate journalists in Czechia. I remember his interview with the most relevant witness (from Pilsen) who testified that Mr Jiří Kajínek, Czech women's most beloved killer (who has managed to escape from many prisons), has indeed killed an entrepreneur and threatened some witnesses. Kroupa (along with Ms Sabina Slonková, a redhead) has also revealed amazing stories about the trip of PM's son Andrej Babiš Jr (who is at least officially psychiatrically handicapped) from Switzerland to Crimea. Although he is really standing on a wrong side of many political battles, Kroupa's purely professional ability to find the relevant witnesses and the data from them seems extraordinary to me.

Science that systematically produces progress only began in Galileo's time

Let me add a few words about the inability of the ancient Greeks and Romans to start the industrial revolution – a fact that is obvious but it is deliberately obfuscated by various retarded (in 2021) warriors against slavery.

These ancient civilizations and their thinkers-in-chief were really great and the seeds of many scientific disciplines were created by the ancient thinkers. I have surely often called their activity "science" a few times, too. However, one must understand that it wasn't a "full-blown science" that really works. The scientific method was introduced by Galileo Galilei (1564-1642).

The world is controlled by the cosmic manager and lawyer

Guest blog by Prof Dr Maria LePen-Sklo-Kaczynski

I am an ingenious intersectional lady. For my whole life, since I was 3 years old, I was working on a theory of everything. And I have just completed it. It seems necessary to quickly publish it because I've heard about some Italian competition that also claims to complete the theory.

In fact, mine isn't just a theory of everything. It is the grandmother of all theories of everything from which all other theories of everything gradually arise. The magic trick is the theories' friendly multicultural cooperation with the other theories and their complete equality. The individual theories are increasingly holistic and intersectional and their grandmother makes them ever more progressive.

Ancient Greeks couldn't have started the industrial revolution

A retarded warrior against slavery – which has been abolished for a long time, indeed – has demonstrated similar comrades' total absence of basic education, intelligence, and common sense. Under the blog post about Newton who benefited from colonialism, he denied the fact that every sensible person knows, namely that slavery (like many things that are mindlessly frowned upon by leftists today) has played an important role for the development of many civilizations, starting with ancient Greece and Rome and later the United States of America.



Plato, an ancient philosopher living in Athens, just returned from a 21st century barber.

Concerning the former, the ancient world, structures that were left wouldn't stand without slaves. For example, The Colosseum was built within a decade but up to 100 thousand slaves had to work on it! We just wouldn't have The Colosseum and many similar gems without slavery. Everyone who claims that slavery shouldn't have ever existed is the same kind of a savage as the ISIS savages who were demolishing the structures in the Middle East. Concerning the latter, the independence of the United States of America heavily depended on cotton, pretty much the most important U.S. export. That's why the South – and slaves that were needed for a sufficient amount of this production – has played a greater role for the very existence of the independent U.S. than the North. The South (with its slaveowners and everyone else) was being "exploited" by the North.

French Sixth Republic and the Confederate States of Europe



France is a global cradle of republicanism. Its republic has been updated a few times. Right now, the country is organized as the (semi-presidential) Fifth French Republic that was established by Charles De Gaulle in 1958. Days ago, 20 retired top generals, almost 100 other VIP officers, and 1,000 other army folks have signed

an open letter urging Macron to return to patriotism
...a Twitter thread with an English translation...
in his interactions with the Islamist separatism that is creating growing no-go zones ruled by medieval dogmas that are in a direct conflict with the French constitution. To allow this creeping transformation means to bring a civil war closer, the military elite warns, and if Macron fails to return the French nation and its secular constitutional principles to the top of the principles that apply across the official territory of France, the military folks promise a takeover of the country by the French military personnel who are claimed to support the generals.

The female minister of defense has showed her utter arrogance and cluelessness and she has both mocked and threatened the former and current heavyweights of the military. On the other hand, Marine Le Pen has endorsed the generals.

Isaac Newton benefited from colonialism



In recent years, neomarxist lies, distortions, and hateful emotions have been penetrating to places where they looked almost unimaginable just a decade ago, including the physics departments. The Daily Mail (and originally The Telegraph which has a paywall, however) brought us news from Sheffield University in the U.K. (which is arguably the country that is more contaminated by the neomarxist poison than any other country in the world):

Students could be told how Sir Isaac Newton 'benefited from colonialism' in curriculum overhaul being considered at Sheffield University
Leaked documents indicate that the university will try to introduce an "inclusive curriculum" of physics by demanding that the instructors include anti-white disclaimers. These disclaimers target Isaac Newton, probably the most ingenious thinker in the known human history, as well as other giants such as Newton's foe Gottfried von Leibniz, Pierre-Simon Laplace, and Paul Dirac.

Ivan Havel, 1938-2021

Ivan M. Havel died yesterday, on Sunday. He was found dead in the bathtub.

He was born on October 11th, 1938, two years after his older and more famous brother Václav Havel, in Czecho-Slovakia. This hyphenation is correct because on October 1st, 1938, following the Munich Treaty, our country got rearranged to the rather disgusting Second Republic of Czecho-Slovakia where various rats and Nazis (not only the Slovak fascists responsible for the capitalization of S) became powerful – much like their counterparts are getting powerful today (especially in the U.S. and Western Europe). The Second Republic lasted for 5+ months up to mid March 1939 when the peaceful Nazi occupation started the full-blown Protectorate of Bohemia and Moravia.

I knew him in person, unlike his brother Václav. In particular, roughly a decade ago, I was giving about three lectures (on 3 different years) after him at a Summer School of Young Philosophers near Olomouc (in the Church of Gradual Decontamination of Virgin Mary in Oak upon Morava, not sure whether my decontamination terminology is used by the U.S. Catholics LOL). In one of those cases, he was kind enough to lend me his laptop.

Swampland: light gravitinos bring their towers, slow down inflation



A gravitino ball. Click the image for a video.

The swampland program deepens our understanding of quantum gravity by refining the conjectures stating that most of the seemingly consistent effective field theories have subtle bugs that prevent them from being completed to consistent theories of quantum gravity i.e. to string/M-theory vacua.

Gravitinos – the supersymmetric partners of gravitons – have entered several swampland hypotheses. For example, exactly one month ago, a paper said that gravitinos mustn't be motionless. Now, in a fresh hep-th Madrid-French-German-Venezuelan paper

A Gravitino Distance Conjecture
Castellano, Font, Herraez and – last but surely not least – Ibáñez ;-) say that the gravitinos can't be too light, or at least they can't be adjusted to be light without additional consequences.

A nation reacts to Derek Chauvin's show trial



A fired cop Derek Chauvin was found guilty on "all charges" involving the manslaughter and murder of an aggressive black criminal. He may be sent to prison for up to 40 years.

Here are the most upvoted comments under an article at iDNES.cz, a mainstream center right news server owned by the Czech PM Babiš' trust. They show a nearly complete consensus in my nation, thank God.

Tomáš Brabec, 43 upvotes / 1 downvote

I don't claim that precisely this policeman is totally innocent but a murder and 40 years in prison, that looks like too much. I wouldn't want to be a cop in the U.S. When I saw the videos from their actions, their left leg is in the grave and the right grave is in the jail.

Decline of education, specialized expertise, and the theoretical background. Stakeholders vs shareholders

Czech politicians have announced that back in 2014, an explosion of a Czech ammo depot near the Slovak border (the village of Vrbětice) was caused by Russian agents. They also wanted to do something with the explosives in Bulgaria. We may get the full intelligence report in days.



In fact, they were the very two same agents Petrov and Bashirov who have allegedly poisoned Skripal using Novičok and yesterday, the Czech Police promoted its photographs of the two men who are "wanted"! Well, it is possible that these "molodtsy" do this much work. After all, the tensions were high in 2014 and the Russian agents' working days should be similarly full as those of James Bond 007. But even if it is true that they contributed to the explosion, I find it obvious that the timing of the revival of this scandal (or a conspiracy theory?) is explained by the takeover of the power over the U.S. by the New Loony Left, their being mental cripples, and their fanatical desire to cripple the relationships with Russia (and others).

Even if the agents have caused it, it is a tragedy that this is being exposed again, in the time when America is becoming nasty against Russia again and Russia is understandably preparing to acquire Ukraine if the tensions run even higher. It is very bad that Rosatom – which is the most sensible competitor, as far as I can say – is being eliminated from the tender to extend Dukovany, the older among the 2 nuclear plants in Czechia (the "nuclear" part in both was made in Russia and it's worked great in those decades). Seconds ago, Russia expelled 20 Czech diplomats, a revenge for the expulsion of 18 Russian diplomats from Czechia. Bad. I am rather uncertain whether the Russian agents are innocent but I am almost sure that the timing now is caused by the rise of the Left in the U.S. – and about our government's role of a cheap slut directly controlled by the D.C. now.

But back to the title.

I finally watched the April 1st-2nd

Prague Café interview with Klaus Part I
Prague Café interview with Klaus Part II
which I previously hesitated to watch, despite the fact that in recent months, I have read, watched, or listened to every single one interview with expresident Václav Klaus, as he emerged as a leading warrior against Covidism (not only) in Czechia. Note that this particular program is called "Prague Café" because Žantovský wants to retake this nice intellectual phrase (and the coffee shops themselves) from the progressives who became associated with the phrase and who consequently reduced the credibility of the phrase dramatically.

Nima, singularities, and the fall of Wilsonianism

MmanuF at Twitter has kindly recommended me this recent, 2.5-hour-long video by Nima Arkani-Hamed:



Because he suspected that I may find it a bit long, being occupied with things like the insane anti-white and anti-Slavic racism thriving in the United Kingdom that has assaulted my homeland through soccer, MmanuF has also helpfully recommended a 10-minute-long excerpt to focus on, 0:20:00-0:30:00, and I did watch that.

Among other things, Nima has declared the end of Wilsonianism. The Wilson paradigm is just wrong, he stated at one point, and you can't organize physics according to the distance scales so that the theory at the distance scale \(L\) is always determined from the theory at a shorter length scale \(L(1-\epsilon)\). Instead, in a theory of quantum gravity (and he may apply it even to some other related theories), there are numerous UV-IR connections and communication in between the scales – aside from some role played by numerical coincidences.

UEFA declared a total war on the Western civilization

Like your humhle correspondent, a large majority of the Czech and Slovak nation is absolutely infuriated by a shocking decision of the UEFA, the European bureaucratic soccer body, concerning the Rangers-Slavia Europa League match last month. Slavia won 2-to-0 and this (surprising for bookmakers) Czech dominance was surely one of the reasons why the Scottish men started to behave insanely.



Ondřej Kúdela, often considered the best Czech defender, is on the right in the front row.

I was warning against the pledge made by Slavia Prague, the best Czech soccer team now, to "respect any verdicts by the UEFA and the Scottish police" because for some time, I have been convinced that these bodies are already full of people without any integrity, common sense, and even without the basic respect for justice, truth, human lives, and the Western values (such as the presumption of innocence).

Classifying viable supergravity theories in 8D, those with \({\mathfrak g}_2\) didn't make it

The Swampland program is a clever filter that eliminates a big portion of the effective field theories with gravity which are not good enough because they violate certain conditions that are necessarily to find a consistent realization of these theories as theories of quantum gravity, i.e. a realization within string/M-theory. In a new paper

8d Supergravity, Reconstruction of Internal Geometry and the Swampland,
Cumrun Vafa (a renowned professor) and Yuta Hamada (a Harvard postdoc) use the existing tools to say "you're fired" to many supergravity theories in 8 (large) spacetime dimensions. Note that 11 (spacetime) dimensions is the maximum dimension of a flat spacetime admitting a supersymmetric quantum theory of gravity, M-theory. 12 dimensions is still possible to some extent, like in F-theory, but two dimensions must be compactified on a torus (or perhaps something else?). Supersymmetric theories above 12 dimensions must be "even more subtle or less physical" if they exist and I want you to assume that they can't exist. In 10 large (spacetime) dimensions, there are 5 different consistent supersymmetric Minkowski-based theories of gravity, all of them are string theories (type I, IIA, IIB, heterotic \(E_8\times E_8\), heterotic \(SO(32)\)).

Markus Söder's Bavarian revolution would probably save Germany

Google censorship: Some creatures harbored by that company have sent me an "order" to erase this text about the fundamental biology because it has to be "fixed" ("Yes"). I moved the essay to another website. These creatures have to be tried for crimes against humanity.
In 2018, Mutti Angela Merkel finally revealed that she wouldn't run again to be the CDU boss and German chancellor after the 2021 elections. She has been the boss of the CDU since April 2000 and the Chancellor from November 2005. Putin is sometimes criticized for his long reign but you may see that the difference between Putin and Merkel is modest in this respect and the selective usage of this talking point against Russia is pure racism.



For quite some time, the leftist media have served a simple story about the future to their undemanding readers and viewers. Merkel would be obviously replaced with AKK, a woman whose name is hard to remember, an even more pro-leftist lady. Let's say that the acronym stands for Analfabertruda Krappen-Krankenhausen. However, in February 2020, she revealed that she just wouldn't run.

Conservative faculty, an endangered species



The most read story at the Harvard Crimson (which is run by students) is a new essay

‘An Endangered Species’: The Scarcity of Harvard’s Conservative Faculty
about the suppression of the people who understand the fundamental ideas of politics at Harvard – and other universities. The pie is quite shocking by itself and I believe that the labels that I added are way more accurate than theirs. Why? Because the people who slightly deviate from the hardcore leftist delusions of the (current) majority are being ostracized and their deviations are being exaggerated and amplified.

So when someone is called "liberal" as opposed to "very liberal", it means that he or she is a hardcore leftist loon who has "sinned" in roughly 2% of the "causes". When they say "moderate", they mean a "moderate Democrat". And I think that even their "moderate" label is just a trick in most cases – they just want to be interesting and look independent (I could name physics bloggers in that category). Most of the people called "conservative" are actually totally standard RINOs, Republicans In the Name Only. I knew one official in the physics department who was a textbook example of such "conservatives". Of course, he wouldn't be conservative in any way that mattered and I couldn't rely on him in anything at all. Finally, all the normal conservatives – that at least consider voting for Trump and who at least sometimes stand on the right side of Trump, as normal conservatives should (because he is a damn former Democrat and still has many leftist traits) – are called "very conservative".

Privatization, revival of North Korea



Dear Kim Jong-un,

I have just listened to your speech in which you sounded rather desperate. The people of North Korea should expect the most difficult period in the history of the country and a hardship that may trump the famine of the 1990s. That could have killed between 0.1 and 3.0 million people. Let me assure you that when I look at you, I don't see any signs of a famine yet!

It looks clear that the economic situation isn't good for the 25 million of the people in North Korea. The already low $1500 GDP per capita seems to be falling further. Note that you use wons as the currency. 900 wons is one U.S. dollar according to an apparent peg.

FNAL: Combined muon \(g-2\) discrepancy grows to 4.2 sigma

Particles have a quantized spin (their own angular momentum) and leptons such as electrons and muons always have \(J_z = \pm \hbar /2\). Yes, the electrons are spinning and it is other ideas than that which you need to modify (you need to switch from classical physics to quantum mechanics).

They also carry an electric charge, \(-e\), which is effectively orbiting around the center of mass at the radius comparable a "typical dimension of the particle" (which is inversely proportional to the particle mass) and therefore creates an electric current.



So the particles also behave just like solenoids and they are also magnets with a magnetic moment. Adopting Feynman's pragmatic definition that I completely sympathize with, the magnetic moment \(\vec \mu\) is a vector that multiplies the magnetic field \(-\vec B\) in a term in the Hamiltonian, \[ \Delta H = -\vec \mu \cdot \vec B. \] How big is the electron magnetic moment? Well, it is (if I choose one form)\[ \vec \mu_s = -g_s \frac{e}{2m_e} \cdot \vec S \] where \(g_s\approx 2\). Note that the Bohr magneton \(\mu_B\) is sometimes used which represents the constant \(e\hbar / 2 m_e\) in the SI units. The Dirac equation gives you \(g_s=2\) exactly.

Covid is ending in UK, CZ... no one must be allowed to obfuscate the fact

Here is the graph of the daily "cases" i.e. first positive PCR Covid-19 tests of a person. It's taken from the main Czech national Covid statistics page.



You may say that we have had about four "waves". You probably see the three big ones on the right but there is also a tiny one on the left, look carefully, which occurred exactly one year ago. In fact, the highest daily number of "cases" in Spring 2020 took place on April 3rd, and it was 333. There is a tongue twister in Czech that involves 333 and the letter Ř. ;-) We had April 3rd last Saturday. That's quite a reason to expect an even faster drop after April 3rd, 2021, as I will argue.

Susskind's de Sitter rant

LHC: Phys-Org about a 2.8-sigma CMS excess in the search for stealthy SUSY.
First, Michio Kaku is releasing his new popular book, God Equation, tomorrow. It could be a similar book about the theory of everything as some books that were published years ago but I guess that God may place a more central role here.

You may also read an interview in the Grauniad where he mentions string theory, colliders, and his view that it may be a stupid idea to obsessively contact the aliens. I can confirm the worries. Alza.cz, a Czech competitor of Amazon, allowed extraterrestrials to be hired. What happened? They have completely dominated the commercials from that moment on. Each ad has a stupid green extraterrestrial with a dwarf's voice. ;-)

An April Fools' Day paper on the swampland rules



On April 1st, 2021 various individuals and companies came with their April Fools' Day pranks, see e.g. this thread where I found the Cybermouse to be particularly well-made. Some scientists have also posted preprints that weren't meant as a serious contribution to science. One of them was from William Kinney, a cosmologist in Buffalo:

The Swampland Conjecture Bound Conjecture
For a few seconds, before I understood it was a prank, I thought that the double appearance of the word "conjecture" was a typo. But be sure it is not a typo. This paper is a "meta-research" that counts the number of papers with swampland conjectures, and tries to please you. Maybe the number of such papers won't be too huge, after all, just a cubed googol so that the papers will require a similar number of visible patches of the Universe to store all the physicists who write them etc.

The point of the paper is clearly to humorously express the author's opinion that the number of papers about the swampland is too high. The detailed jargon-filled, science-like-sounding propositions aren't hard to invent in real time, I would probably end up writing a similar April 1st paper if I wanted to express the same point (although I hope that mine would be funnier).

How holograms work



You may really look at the mouse hologram from different directions.

The holographic principle states that a theory of quantum gravity is secretly hiding the information about (spatially) 3-dimensional objects in a plane ("photographic film" or "holographic screen") that is just (spatially) 2-dimensional i.e. whose dimension is lower by one.

In both cases, the information about the extra dimension, the "depth of a point", is encoded in the typical wavelength of an interference pattern that appears on the screen. In some generalized sense, dinograms or stereograms do exactly the same but the holograms can really store the information even about points that are overlapping each other, not just about the "closest layer".



Let's try to explain how the image of a 3D object such as this mouse is encoded in a hologram a bit more quantitatively. We will need a coherent source of light which has the precise (angular) frequency \(\omega\). A laser. Dennis Gabor, a powerful Hungarian theorist, invented the holograms in December 1947 but the lasers only emerged as "real things" in 1960 and it took a few years for the holograms to be made, too. Gabor got the 1971 Physics Nobel Prize.

Impact of Covid within the Czech age-sex pyramid

According to the standard global Covid data, my Czech homeland is the world's #1 country above 1 million according to the "cases per capita" as well as "deaths per capita".



Note that this 2017 pyramid shows the local minimum of the width in the age of 15-19 which means that the "decline of the population" looked worst around 2000 and the natality started to grow again.

If we switch to our official national tables, the country of 10.7M (M is mega, a million) has detected 1.546M people as positively tested (14.4% of population) and 26,765 people have died with Covid so far (0.25% of population). It is generally agreed by the epidemiologists that the actual percentage of the population that has acquired Covid antibodies is at least around 50% and probably between 50% and 100% – and many of us think it is much closer to 100% than 50%.

Facebook has banned the voice of Donald Trump

ItIsWhatItIs kindly informed me that the usual Google searches that have pointed to this website has disappeared. I cannot really validate such claims, your measurements will be welcome. It's possible that Google behaves differently according to users or their places.

Meanwhile, (mainstream conservative comedian of a sort) Steven Crowder's accounts were blocked on Twitter and especially YouTube, despite millions of subscribers (and millions of views per video). The Twitter suspension could be temporary (before it won't be); the YouTube has issued a hard one-week block along with the permanent demonetization.

While doing so, YouTube has violated all of its previously declared rules such as the pledge that individual channels whose content is distinct may only be punished separately. Crowder plans to "fight like hell".



But this other Orwellian act of the day seemed even more insane to me. Lara Trump, the wife of Eric Trump, recorded the first video interview of Donald Trump after the fraudulent inauguration of Joseph Biden.

The 18-minute-long video above – which I took from her theRightView.com – sounds very relaxed, pleasant, yet important. It is about the decline of the U.S. under the Biden regime, the disappearance of the freedom of speech; the Southern border and other international topics; and the hope that he will return to D.C. She also posted it to a Facebook account and an Instagram account. What happened?

The status was deleted. But it is the explanation that Lara Trump has received which is absolutely shocking – and tragicomically so. In the wake of the previous ban of Donald Trump, "Facebook incl. Instagram doesn't allow the voice of the U.S. President Donald Trump anywhere on their servers". Wow. ;-) Any account that posts something with Trump's voice may be penalized, too.

Pinball, heavy strings, black holes, saddles, and chaos

The new hep-th preprints mention the word "string" 27 times today – in 4 abstracts of new hep-th papers, 2 new cross-listed ones, and 2 replacements. I think that the most interesting paper in this "string set" is

Chaotic scattering of highly excited strings
by (QCD co-father) David Gross and Vladimir Rosenhaus. It is about some high-energy scattering, in this case that of heavily excited strings, the the chaos that it exhibits.

RIP Petr Kellner, the greatest Czech financier ever

In the morning on Monday, millions of Czechs (starting with the likes of me) were shocked by the event that occurred on Saturday night, local time, near the Knix Glacier, 50 miles East from Anchorage, Alaska.



During heliskiing (which is skiing in which the lift is simply replaced with a somewhat more expensive helicopter), more precisely helisnowboarding, in their case (!), five people died when the Airbus AS350 B3 helicopter (the same model that landed on Mt Everest in 2005) crashed, including the wealthiest Czech, Petr Kellner. Snowboard champion David Horváth (CZ), 48, was the only survivor, he is hospitalized and in stable condition. The five killed in the Saturday accident were identified as (the guide) Gregory Harms, 52, of Colorado; Petr Kellner, 56, and Benjamin Larochaix (France-born snowboard coach and friend paid by Kellner), 50, both of the Czech Republic, and two Alaskans, (one of the best guides here) Sean McMannany, 38, of Girdwood, and the pilot, Zachary Russel, 33, of Anchorage, Alaska State Troopers said Sunday. See this local video that says something about the other men and the details of the event.

Comenius, the father of modern education

On March 28th, 1592, John Amos Comenius was born to a Protestant family in South Moravia, in or near the Uherský Brod (the precise place is not known).

This "Teacher of Nations", as he is nicknamed in Czechia, or the "Father of Modern Education" or "Father of Christian Education", considered himself Czech and spoke (and wrote) Czech perfectly but his family name was actually Hungarian, Szeges (CZ translit.: Segeš; Hungarians' S and Š is interchanged relatively to Polish). Well, the adjective "Uherský" in the name of a town does actually mean "[Old Royal] Hungarian" in Czech and Hungary is not far.



A CSK [Czechoslovak koruna, a retroactively created acronym] 20 banknote with Comenius. He is also at the modern CZK 200 banknote.

Well, the most convincing birthplace is Komňa, a village in the UH District of the Zlín Region, because it would explain his Czech adopted surname Komenský (Latin: Comenius); the adjective based on Komňa is Komeňský which is almost the same LOL.

Maximum generality isn't always the same as mathematical depth

An ATLAS excess: a new LHC paper has an interesting excess on Figure 6, Page 13, in the decay \(H\to aa\to bb\mu\mu\). The invariant mass \(m_{\mu\mu}\approx 52\GeV\). The confidence level is 99.95% (3.3 sigma) locally, 95% (1.7 sigma) globally. Note that in 2018, the CMS saw a dimuon excess at \(28\GeV\), close to a 2016-retro-seen \(30\GeV\) dimuon excess at ALEPH (LEP).
After he read my thoughts about the supremacy of physics-like proofs, Mr H. Turtledove (CZ) has exchanged a dozen of interesting e-mails with me that revolved around the importance, depth, mathematical ideas, physical ideas, and their relationships. I have tried to persuade him that the "fundamental depth in theoretical physics or string theory" is an entirely mathematical characteristic which is nevertheless important both in physics and in important mathematics. A mathematical characteristic may be crucial in physics because the laws of physics are constrained primarily (and perhaps only) by mathematics.



One obvious defining trait of mathematical thinking is the tendency to generalize. If you are asked to compute the total area of three yellow triangles and there is an obvious generalization to \(N\) yellow triangles, it is natural for you as a mathematically inclined person to solve the problem for a general \(N\in\ZZ\).

If you are a baby and you know how to generalize an insight to complex numbers, you should do it because that's what babies are all about. Similarly, if you're a schoolkid, you invent an interesting theorem, and you feel it could be generalized to \(D\)-dimensional shapes or cohomology or K-theory classes or derived categories of coherent sheaves, you should establish the generalization because that's what schoolkids normally do. ;-)

Erdoğan's alternative "science" on interest rates



Turkish Rondo by Wolfgang Amadeus Mozart, edition by Mrs Eva Pillarová. Note that the shabada lyrics coincides with that of Nohavica's song about the Arab who is touching Nohavica's wife.

The Turkish economy has displayed some high, 15% or so inflation rate. It would be unacceptable in almost all standard Western countries (and some others). In November, when the U.S. dollar was already worth some 8.40 Turkish liras (see USD-TRY charts), the Turkish president Recep Tayyip Erdoğan appointed a respected hawk Naci Ağdal to the central bank who has apparently tamed the inflation when he raised the interest rates from 10% to 19%. The lira appreciated up to 5.95 per dollar in mid February 2021.

However, one week ago, the dissatisfied president fired him and replaced him with an unknown dove and the lira instantly went from 7.2 to 8.0 (now) per dollar. What is remarkable is the the president's maneuvers are built on his "science" whose basic tenets are

The interests are the root of all evil.
High interest rates also cause high inflation.
Amusing and cute but dangerous.

Covid mania has only supported junk science, not genuine science



Most of the Western countries have been putrifying under the influence of the New Left for years – contaminated and damaged by the evil activists with their woke culture, anti-male sexism, anti-white racism, anti-nation-state drive and the universal pro-migration globalism, the global warming hysteria, and a few more. But the coronavirus epidemics has sped up all these pathological tendencies and unified them into a wide, loosely connected stream of devastating political causes.

The support for the nationwide Covid restrictions belongs to the authoritarian left-wing corner of the political 2D plane (or 3D space) for obvious reasons:

  1. they restrict the individual economic freedom and gives the power to the central authorities and politicians teamed up with the self-anointed would-be experts
  2. the virus is a good excuse for the unprecedented redistribution of the money; the budget deficits are incredibly huge and mostly flow to the privileged classes and occupations and the well-connected people; a much greater portion of the people's income and wealth is being decided centrally, not by the free markets
  3. the memes about the existential threat are a good excuse to restrict even "political" civil rights such as the freedom of assembly, religious freedoms, and the freedom of speech
  4. indeed, the very human lives, the right to move, and the individual health was being nationalized (have you been annoyed by a doctor claiming that his or her expertise gives him or her the right to own and control your body?); billions of people have really lost their right to decide about their own bodies and health – these decisions, and indirectly the bodies themselves, belong to the self-anointed experts and/or their allied politicians and must behave in a way that serves the public health, as argued by the self-anointed powerful experts
There may be a few effects that I have forgotten and each of those that I didn't forget have many overlapping aspects and flavors. A priori, these effects are independent of each other and it may look like a coincidence that all of them are considered "left-wing". But it is not really a coincidence and these effects aren't really independent of each other because the left-wing recipe for the society is about (1) collectivism and (2) the elevation of groups that are said to be oppressed because they are unsuccessful in some way, and it is obvious why events such as the Covid epidemics help to strengthen the case for all these left-wing memes.

More than a soccer match

Lots of Czech pundits, including former prime ministers Paroubek and Topolánek (and Klaus Jr who announced the end of his political career today), have expressed nearly identical opinions, with quite some insightful details.



Ondřej Kúdela in the typical half-red, half-white Slavia shirt.

I chose to translate this text by Patrik Nacher.

A commentary: more than a soccer match

The [Europa League] soccer match between Slavia Prague [the best team in Czechia right now, no loss in ~37 recent games, China-owned] and the Scottish Glasgow Rangers has unwillingly unmasked several aspects of the present which vastly transcend not only this single match but all of soccer and the sports as a whole. I have observed at least three interesting moments: Western vs Eastern Europe, verbal vs physical assault, and racism built on the presumption of guilt. And the double standards at numerous places were just some additional proverbial cherries on a pie.

Gravitino must never be motionless? A swampland hypothesis

In a new hep-th paper

The Gravitino Swampland Conjecture
Edward W. Kolb, Andrew J. Long, and Evan McDonough (Chicago/Houston) propose a new swampland principle – a new condition that must be obeyed for an effective field theory coupled to gravity to be capable of a consistent completion to a regime of quantum gravity and/or string theory. They postulate a simple rule:
The gravitino speed must never drop to zero in any vacuum and any conditions.
If true, such an assumption also has consequences.

Can India reach the average wealth?

India is one of the oldest civilizations, the largest democracy in the world, and the second most populous country on Earth. With 1.35 billion people, it is just a few pips beneath China which stands at the top with its 1.39 billion. But India's population will surpass that of China in a few years and should brag some 1.64 billion around 2050 when it will be the most populous country.



The average IQ of India is said to be 81, well below China's 104, but it changes nothing about the fact that most of the people in my region consider Indians to be our more suntanned cousins, members of the same race. The reasons are particularly obvious if you look at the language: the grand family is called Indo-European (or, in the Greater German realm, Indo-Germanic) for a good reason. Slavic languages end up being particularly close to Sanskrit, an ancient Indian language (but also to Persian), and the overlaps are sometimes so stunning that I would be willing to include Sanskrit among Slavic languages. Check e.g. this video.

Dissatisfied Czech citizens' manifesto

WE WANT TO LIVE NORMALLY AGAIN
Written by Václav Klaus

We, the citizens of the Czech Republic, who – as is becoming increasingly manifest to us – aren't sufficiently politically represented in the government and the Parliament, are expressing our deep dissatisfaction with the state of our country and the conditions in it. They have been devastated by the catastrophic policies of our government which has evolved into a serious threat for freedom and democracy. The current distribution of the political forces makes us gravely concerned about the political evolution in the wake of the Fall 2021 Parliamentary elections, too.

Superluminal spaceships vs common sense, special relativity

I was amazed by the number of people who are apparently "excited" by the – constantly recurring – claims that someone just made a big step towards spaceships that move faster than the speed of light. In the scheme of elementary science as I understand it, the failure to understand that superluminal objects are impossible in theory – and equally ludicrous in the engineering reality – represents the same proof of complete scientific illiteracy as the belief in the perpetuum mobile or omnipresent deadly geopathogenic zones, among many other things. Why are so many people not getting these basics – and returning to this stuff, often as if it were one of the greatest trends in physics?

It has been known since the 1905 discovery of the special theory of relativity by Albert Einstein that the localized objects in this world can never move faster than the speed of light (in the vacuum: 299,792,458 m/s). Massive objects can't quite reach it (although the LHC protons get extremely close, 99.999999% of the maximum speed, just 3.1 m/s below the limit); the photons (particles of light) and other massless particles are obliged to move exactly by the speed of light.

OK, so one of the parts of science that the proponents of the "warp drives" (a popular "brand" synonymous with the superluminal spaceships) are completely denying is the special theory of relativity. They don't really care and if you ask why they are denying this pillar of modern science, they may either tell you that 1) they don't trust it because of Einstein's ethnic origin, an explanation that is known as the "Aryan physics", or 2) they believe that Einstein's later theory, the 1915 general theory of relativity, allows us to suppress the basic conclusion of the special theory of relativity.

Hiroshima supernovae and the journalists' selection of science



Maxim Turbulenc's disco version of the "Dwarfs' Wedding", a fun Czech (originally) country music song by Rangers/Swimmers (and/or Zdeněk Svěrák [lyrics] and Jaroslav Uhlíř [music]? That was a bit confusing!). Numerous stories about the Snow White's seven dwarfs attending Dopey's (Shmoodla's) wedding in the forest, after Dopey returned from the military, are presented with cute diminutives everywhere; so e.g. someone played a little Mendelsohn on the little organ, and they were cooking meat in a little Papin's pressure cooker. When I translate it from the ultimately playful Czech language to the much less poetic English, it sounds so dull!

Yesterday, several people asked me about a catchy preprint

Actinide crystallization and fission reactions in cooling white dwarf stars
... by C.J. Horowitz, M.E. Caplan ...
because it was accepted to PRL, a widely admired journal, and lots of the media outlets have covered the story. The popular headlines obviously sound much cooler than the boring technical title above, e.g. New Paper: Space Is Full of Naturally Occurring Atomic Bombs. And I would say that in this rare case, these titles are eye-catching but fair summaries of the proposal.

Supremacy of physics-like proofs

They lead to the greatest generalizations, deepest understanding

Theoretical physics is close enough to pure mathematics and the subjects greatly influence one another (although this intercourse was hyped as politically incorrect by several waves of misguided ideologues in mathematics such as the Bourbaki group). Many interesting findings in mathematics are inspired by physics and physics-like systems; physics needs the ideas and tools of mathematics to understand things rigorously.

One aspect of this relationship is the existence of mathematical proofs that are either originally found by physicists; or that are made simpler and intuitive by physicists. There are many examples but let us pick the identity that Carl Jacobi, a classical liberal who died young, incredibly proved in 1829.

CDC vs. Common Sense




Guest blog by Dr Paul E. Alexander et al.

The death of Common Sense begins with the words initiated by the morass of Bureaucracy couched in safety and security. Indeed, and according to past President Ronald Reagan, the most frightening words to hear in the English language are para ‘We’re here from the government and we’re here to help you!’ The underpinnings of such beginnings appear benign and with benign neglect the malignancy storms through, metastasizing arboreally through the veins of the entire system. The world is seeing such a death these days.

Marc Morano: Green Fraud

Marc Morano runs ClimateDepot.com but I actually believe that it is just a small fraction of his amazing activities against the climate hysteria and its political consequences. I have previously enjoyed Climate Hustle 1 as well as Climate Hustle 2, professionally made, highly entertaining, and insightful movies. He has previously published The non-PC guide to AGW.

I was happy to read his new book that you should pre-order and that will be out on March 23rd, Green Fraud, and I am proud to be cited at about 5 distinct pages (not counting the notes) and to be among some three dozens of the people who are being thanked to. Why? Because Morano really is the world's #1 consequential climate skeptic from many perspectives, a point that is elaborated upon in Chapter 1.

Before you get to that chapter, you see that this book has been praised by heavyweights such as Sean Hannity, Will Happer, and the late Rush Limbaugh (plus Levin, Inhofe, Bozell). Later, you may read quite some entertaining praise from other sources – and feel the immense respect that is hiding in the colorful criticisms by his well-known foes. During the years, we have also seen quite some death threats that he got from global warming fanatics (or one of them with dozens of identities?). But that doesn't quite exhaust the diversity of the viewpoints on Morano as a man who excites others. I've seen numerous climate alarmists who were terrified of Morano because he's such a nice beloved uncle on TV. Even in Russia, kids "no longer want Pikachu, the want Morano" (ribionki Pikachu nye khochu, ribionki khochu Marca Morano). And he just sounds extraordinarily calm and organized yet humane.

Edwin's understanding of QM: Part II, uncertainty and the weirdness of classical physics

If you haven't watched the first part of Edwin Steiner's online lectures on quantum mechanics, you are encouraged to click and listen to that first part because (like in serious physics), your new knowledge depends on the familiarity with the previous one.

At the beginning, Edwin returns to the very late 19th and early 20th century when the most important physics papers would be written in German. Sadly for Germany, around 1945, the European country lost its best Jewish physicists as well as the non-Jewish, i.e. Nazi physicists (I hope that this internal classification of the German-speaking physicists up to 1945 is accurate and detailed enough for the demanding readers!), and that's why Edwin switched to English as the lingua franca of physics, too.

Feynman's puzzles answered by the principle of least action

Laissez-Faire principle of least action is a deep, philosophy-like wisdom of physics that isn't really taught and encouraged

We had discussions about many things including the Covid-19 strategies with a friend. Sweden has imposed almost no mandatory restrictions centrally. The country's curves (look e.g. at the deaths/avlidna in the lower right corner) look very smooth and organic. Covid-19 is largely over in Sweden and they had two almost identical waves. Each of them has killed some 6500 people. The second, winter-era wave had to arrive because the herd immunity obtained after the first, spring wave wasn't enough for the winter condition when the viruses spread more easily and \(R_0\) is higher.



"Do nothing" really is the best strategy, up to some details. We may go even further. It is a good idea to isolate the old and vulnerable people if you want to reduce the number of deaths but "prescribe nothing" is the best approach once again because the people will naturally shield themselves according to their fear which is generally correlated with their actual risks.

"Do nothing" is optimal in basically all of classical physics. What do I mean? I am talking about a class of problems that Richard Feynman has loved because they encode quite some part of the "real expertise of a theoretical physicist". He was surprised when he saw that many colleagues couldn't solve them.

Fake risk, fake growth stocks, and misallocation of capital

Bitcoin is the world's largest bubble, its total value is just over $1 trillion now. It's not a conventional stock although it is right to consider it a stock of a worthless company. Tesla was the other big bubble and almost reached the capitalization of $0.9 trillion. These are no longer negligible amounts of money – note that one trillion is about 1% of the global GDP per year. But these two are still just two tips of a more complex iceberg.

I've discussed one way to generalize these bubbles, the Gamestop and meme stock mania. We may look at all the stocks whose price is insanely inflated by totally dumb sheep, mostly retarded children, who have learned to read and who are using bizarre servers such as Reddit.com as sources of "orders what they will immediately do with the money but without any questions".

Gamestop, the most notorious meme stock, has reached some $400 before it returned at least to $40. However a new wave of insanity has brought the stock to the current price above $190 again. This kind of insanity won't evaporate before a sufficient number of these braindead sheep suffer or e.g. starve to death. But we live in a hyper-PC world where their extremely well-deserved misery is discouraged by the system which means that this kind of behavior is really encouraged. So this idiotic behavior will probably be a part of the world for a long time and although I am often an optimist, I expect this pathology to keep on growing.

Extreme leftists react to the reopening of Texas

Two days ago, the governor of Texas (the state with the highest number of old-generation Czech Americans, and they know how to make koláče/kolaches there; search for Czech Texans on YouTube) Greg Abbott brought great news to his folks:


So no restrictions, no closure of shops or schools, and no mandatory face masks. The justification is clear. The Covid lockdowns have stripped the people of trillions of dollars, much of their freedom, fun of life, and there exists no indication that the lockdown U.S. states saw better (let alone significantly better) Covid-19 results from the medical viewpoint, see the map.

A huge fraction of the people who actually create values, like the small business owners (i.e. unlike the people who are comfortably living out of the taxpayer money, doing nothing or almost nothing, and pretending that they're morally superior despite being this kind of despicable parasitism!), have been existentially threatened. Some of them saw their dreams evaporate.

Gregor Wentzel and the path integral

Provoked by the previous blog post about the path integrals, Frank S. sent me two fascinating 1924 papers by Gregor Wentzel which "almost" defined the Feynman's path integral definition of quantum mechanics but two decades earlier (and a year before Heisenberg started quantum mechanics as we know it). If you find English somewhat more comprehensible than German, like I do, you may read a 1998 review of these papers by Salvatore Antoci and Dierck-E. Liebscher

Wentzel's Path Integrals (PDF may be downloaded there)
which probably contains more than what we will actually ever need, unless we plan to write a detailed book about the history of science. First, Wentzel may sound like a forgotten name. But on this blog, you find it in two previous texts. He had something to do with dispersion and Kramers etc. After all, Wentzel's name starts with a W, like WKB does, and indeed, he is also the first guy remembered in the WKB acronym. But how many people know what (J)WKB stands for now?

Just a Czech comment. Wentzel sounds very German because it's spelled in a German way. But it's just a Germanization of the Czech, Slavic name Václav. Why? Because the original form of the name, used some 1000 years ago, was Věnceslav (like Víceslav) which really means "more fame" or "more famous". Unless it literally means "wrath/crown of fame", as some sources say.

Ironically enough, "Boleslav" had the same meaning ("bole" is still a Russian word for "more"). Boleslav was the brother who murdered saint Václav. They were brothers but their first names had the same meaning. English adopted the old Czech "Věnceslav" as its (Good King) Wenceslaus, German shortened it to Wenzl or Wentzel, and modern Czech shortened it to Václav (or, colloquially, Vašek or Venca, the latter is probably a Bohemization of the German name Wentzel; note that Venclovský was the first Czech who swam over the English Channel while David Vencl – the surname is just a Bohemian respelled Wentzel – recently improved the world record in swimming under the ice to 81 meters, a great Czech dude)...

Feynman's path integral & superpositions of histories

What happens in between is "everything", Feynman diagrams are another basis of the "space of histories"

In January, I was asked on Quora What happens in between the initial and final states in quantum mechanics. Well, everything happens and nothing happens or it's meaningless to say what happens. A basic principle of quantum mechanics is that the results of the measurements of observables \(L\), i.e. statements \(L=\lambda_i\) obtained by measurements, are the only facts. Quantum mechanics is a set of rules to predict or derive or explain some facts (or their high probability) from other facts. A theory in classical physics could be given this description but also a "more specific one", a classical model of something, but the more specific one has been impossible after the discovery of quantum mechanics.

Feynman's path integral approach to quantum mechanics is a very explicit way to see "in what sense" everything happens. Assuming some initial and final states (in a position-like basis, to simplify the questions about the bases of initial and final Hilbert spaces), the probability amplitude for a transition (i.e. the complex number that determines the matrix element of a unitary evolution matrix) may be calculated as\[ {\mathcal A}_{{\rm initial}\to {\rm final}} = \int{\mathcal D}x(t)\,\exp(iS/\hbar) \] where the infinite-dimensional integral goes over all trajectories \(x(t)\) connecting the points \(x(t_{\rm initial}) = x_{\rm initial}\) and \(x(t_{\rm final}) = x_{\rm final}\). If you consider generic initial wave functions, you must pre-add two additional integrals over \(x_{\rm initial}\) and \(x_{\rm final}\), the weights \(\psi_{\rm initial}(x_{\rm initial})\) and \(\psi_{\rm final}(x_{\rm final})\), and then the integral becomes the integral over literally all functions \(x(t)\) defined on the interval of time between the initial and final time (be sure that while I admire \(\rm\TeX\), it's faster for me to write these mathematically heavy sentences in words than in mathematical symbols!).

Triangles in a row

My friend Prof Vlasta Dlab (Ottawa-Bzí) sent me his solution (which will appear in a Czech MathPhys Journal) to the following puzzle (well, its generalization from \(4\) to \(n\) triangles):



He was deeply dissatisfied with a solution of this puzzle on YouTube (posted in January 2021) because a part of that derivation is a blind application of a geometric formula (a sine formula for triangular areas) which doesn't really reveal the simplicity of the situation and its independence of angles, precise shapes... I completely agree with Vlasta. While the YouTube solution looks short, it uses an excessively heavy and irrelevant tool, and the person using these methods would probably waste too much extra time if he were supposed to solve a nearly isomorphic problem.

A good mathematician should look what matters and what doesn't matter. And an important point about this calculation of areas is that the angles don't matter at all! Correspondingly, you shouldn't be using the Pythagorean theorem, a sine formula for triangular areas, Heron's formula, and similar tools that deal with angles and, almost equivalently, with ratios of lengths of line intervals that go in different directions. In a good, conceptual solution, the "square roots of three" and similar things shouldn't appear at all (while they appear in the YouTube video).

SJW awokening harms mathematics more than communism did

At Twitter, PartTimeRacer has informed me about the essay (at "Common Sense With Bari Weiss", a brand that hasn't built name recognition with me so far)

There Is No Such Thing as "White" Math
by Sergiu Klainerman, a Romania-born Jewish male mathematics professor at Princeton. (Here we do try to maximize the information that readers might find important, and given the sociological focus of these discussions, rightfully so.) I have mentioned his name four months ago.



Bucharest

Klainerman is introduced as someone who left the Soviet bloc and who could do wonderful things in the U.S., partly because mathematics is a great equalizer. The solid method to look for the right and (to eliminate) wrong answers is universal across cultures, the beef of mathematics doesn't depend on the white race or any other group of humans in any way. Well, Klainerman is still PC in the sense that he likes to "assume" that mathematics skills are universal across cultures etc.

Do dogs and cats depend on eating plants?

A better, more strategy-oriented, and more quantitative "life sciences" curriculum for kids should prevent people from becoming scientifically illiterate vegan or Luddite ideologues

Last night, aside from many other interesting things ;-), I "learned" from an amateur Prague-based public intellectual that it is great to feed dogs and cats with a balanced diet rich in fruits and vegetables. Also, it turned out that animals in Nature never fight and if an animal ever dies, it is only an animal that was going to die very soon, too. The predators are very decent and avoid any physical violence. It was entertaining to some extent but I just don't have the stomach to stomach similar things that come from an adult for hours (unlike cows that have four stomachs and can stomach everything, as we will see).



Two weeks ago, I argued that a proper and captivating education of history for kids should be filled with the basic capitalist financial literacy. Now, I think that that the kids' biology classes should be full of adventurous and emotionally relevant National-Geographic-style stories about animals, something that the kids become involved in, and something that should ultimately teach the logic of Darwin's theory, evolution, and natural selection to the kids.

In fact, these two proposals are completely analogous – in some sense, they are almost the same thing. Capitalism is a counterpart of the "struggle, competition, and cooperation between animals" that is brought to the world of investment and corporations. The reasons why capitalism and natural selection lead to improved well-being of the whole and progress are fundamentally the same.

Edwin's understanding of QM: Part I, physics vs mathematics

Today I have listened to a large number of interviews, especially on the brilliant Free Universum Radio hosted by the smart opera singer Ms Martina Kociánová. But I also saw a 10-day-old quantum mechanical video with Edwin Steiner.

Millions of Czechs will strongly violate the draconian restrictions

It's often said that 40% of Czechs totally oppose most of the non-cosmetic Covid-19 restrictions and my reading of the in-real-life interactions as well as the Internet discussions agrees with this estimate (yes, of course, I am inside this 40% group). And yes, of course I think that this natural support for "ordinary freedoms needed to live ordinary lives at the individual level" (something that even all the foreign overlords respected at almost all times) is also the main reason why Czechia leads the world in the number of "Covid-19 cases" per million people – and I am proud about it. The number of Covid-19 cases really is a great approximation for a moral virtue in a nation. After the announcements last night, the anger in the discussions is intense and omnipresent.

Even though the Czech Parliament has refused to extend even the mild state of emergency that has existed so far, the Czech government has decided to introduce a new one with much more draconian measures from Monday, March 1st. So the face masks are mandatory outside and on the workplace; cloth masks aren't enough; two face masks or a respirator are needed in the public transportation (and...) and the grocery stores, almost all other shops are ordered to be shut down (exceptions are scheduled to drop by 50%, flower shops remain the most surprising exception, they're claimed to be open to remember the Covid victims but only 1-2 persons die in a district each day and what about the remaining thousands of flowers?).

But the restrictions on the movement seem most shocking and they almost resemble the Australian insanities. Every movement to another district (Czechia is divided to 76 districts plus Prague that will act as one district, good for them) must be justified by some incredible paperwork, a receipt from the employer or the doctor or something like that. So any "casual" movement in between the districts (like that of the people who have a romantic relationship in the adjacent municipality; or even the visit to parents or kids who live elsewhere) is claimed by the government to be banned from Monday (millions of people actively say that this is an inhuman restriction). One can walk a dog but only 500 meters from his home, and only during the day. Very shockingly, people who will be located on their cottage on Sunday night must stay there (or at least in the same district) for three weeks (the cottage will legally become their home for these purposes)!

Prague's municipal court endorses a freshman, orders in-person learning to be restarted

Every court must have its opinions about what is legal and constitutional

As "citizen" has pointed out, the Municipal Court in Prague decided against a high school where teachers were getting a salary while not fulfilling their duty to teach a student in person (which is what teachers do at most schools not only in Czechia now, as you know). The freshman T.N. has sued the school and won. The essence of the verdict is the judges' opinion that the state of emergency that was started on February 15th (last Monday) is the same as the previous one and whose extension was vetoed by the lower chamber of the Parliament on February 10th.



Gymnázium Na Zatlance, the high school that lost a lawsuit and was ordered to restore the proper education

Because there is no legally valid state of emergency now, the school has no valid justification for not fulfilling its pedagogical obligations.

Now, the prime minister has used a sleight-of-hand by emphasizing that a "fundamentally new" state of emergency started on November 15th, after the regional governors asked the government to extend the state of emergency (a discussion with zero legal implications) despite the lawmakers' veto (according to the prime minister, the state of emergency was "new" and responding to "new conditions" but this is in no conflict with his assertion that nothing changed about the restrictions between February 14th and 15th). The prime minister wasn't too clear why the state of emergency with the same cause and the same justification would be "new". But he must have believed that simply by saying it was "new", the courts would consider it "new": maybe it is because you never enter the same river twice. To say the least, he wanted 10.7 million Czech citizens to believe a story like that and to behave as if the state of emergency had been lawfully extended. According to the law, the government has the right to declare a "new" state of emergency at any moment. The government has to inform the Parliament and the new state of emergency may be later terminated by the Parliament.

Yellen, Lagarde vs Bitcoin

Two weeks ago, the president of the European Central Bank (ECB) Christine Lagarde said that Bitcoin was unlikely to be held by central banks, it is used for funny business. At about the same time, Elon Musk added the word "Bitcoin" to his Twitter profile. The Bitcoin price added some 15% in hours as a result – as millions of dimwits interpreted the comment as an order to BUY BUY BUY.

In the process of merging the two most notorious one-trillion bubbles of the contemporary crazy financial world, the uncompetitive carmaker Tesla bought $1.5 billion worth of Bitcoin and said that it would accept it as compensation. The supporters of Tesla and Bitcoin bubbles are highly overlapping sets of hopeless idiots. Thinking positively about one of these bubbles is quite a sign of the person's stupidity – but celebrating the hybridization of these two bubbles (in which all the risks amplify each other and the absence of any beef is illuminated from both sides) is probably yet another level. Of course, Tesla hasn't ever produced any real profit from cars so the Tesla profit from the appreciation of BTC surpassed all the conceivable profits of the carmakers that have something to do with cars. ;-) Imagine how fudged up the people have to be if they see nothing wrong about such "money" and such "carmakers". Do you really prefer a world where "producers" actually make their billions by manipulating millions of simpletons by ordering them BUY BUY BUY instead of producing useful, competitive products?

If your IQ happens to be below 70 but you were capable of learning to read, anyway, let me remind you that the fair Bitcoin price has always been and still is $0.00. Among Bitcoin cultists, this number $0.00 isn't applied too accurately, they are paying about $50,000 (and the peak was $58,354 a day or two days ago). In early 2019, the price at which the cult was trading the $0.00 Bitcoin was $3,100 (a local low). The 16-fold increase in these 2 years basically means that the number of dimwits who have been persuaded that it is clever to invest into this bubble grew by a factor of 16. Each of them evaluates the Bitcoin price inaccurately and the inaccuracy per person grew from the $3,100 discrepancy to $50,000, by the same factor of 16. That's why we could say that the total amount of stupidity contained in the Bitcoin cult actually grew with the second power of 16, by a factor of 256. I think that the people in this cult do believe that by collecting a sufficient number of dimwits and inflating the bubble to a huge enough size, they change the truth and $0.00 will be equal to $50,000 or something (just like when Bill Gates says that 2+2=4 is just a racist invention and other answers may be made more correct when minority SJWs are fighting hard enough). Sorry, idiots, it won't. The Bitcoin is still worth $0.00 and you are just a larger pile of more hardcore morons than what you were before.
