### 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!

### 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

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.

### The Gates fund "math is racist" junk

The number of such shocking news is absolutely terrifying these days. But this one was particularly disappointing minutes ago:

Rantz: Bill and Melinda Gates Foundation bankrolls ‘math is racist’ lunacy
Far left activists are spreading the "A Pathway to Equitable Math Instruction" for children who are 12-14 years old and this absolute garbage is being funded by Melinda and Bill Gates. You can find relatively recent blog posts (pre-Covid posts, however) where I was still expressing a hope that Bill Gates was far wiser than other billionaires who run similar charities and "charities". I've liked him as a "Microsoft fan" when I was an undergrad and my sentiments got even more favorable when I learned tht he coded the BASIC for my Commodore 64 which I have spent a lot of time with as a boy. But should these things be enough to give thumbs up to a man?

### Kosovo PM elect wants Kosovo to be annexed by Albania

Kosovo was the cradle of the Serbian statehood. In the recent century or so, Albanians over-migrated to this administrative region of Serbia (which was a part of Serbia even in the times of Yugoslavia) and over-copulated. The migration and the higher natality rate made them 90% of the population by now – well, it's been the case for a decade or two.

In 1939, when Adolf Hitler turned Czechia into the Protectorate of the Third Reich and bragged that he would be the greatest German at Valhalla ever, Benito Mussolini felt like the inferior member of the Axis and invaded Albania which was turned into a Protectorate of Italy. Well, he still remained inferior because Albania has always been heavily inferior to Czechia but let's not be distracted by such details LOL. This Italian-controlled Albania was supposed to expand to new territories including Kosovo but Mussolini and Hitler lost the war, Hitler wisely commited suicide, and victorious Serbia took control of Kosovo again.

In the 1990s, I was rather neutral about the Yugoslav wars. I had mixed feelings about almost everything. It was partly because like millions of Czechs, I still found some uncritical attitude to the West natural and the West wanted to punish Serbia. Poor Milošević – who was really nothing else than a Serbian clone of Joe Biden or something socialist like that – was promoted as the ultimate Devil. But I felt something really terrible was taking place. These days, and for a decade, I have no doubts that the Serbia were (and are) basically the good guys and the Kosovo separatists were the worst ones among the Serbia's foes. They were also responsible for drug sales, organ trafficking and other things.

### Irreversibility of measurements is straightforward

For some reasons, the recent 24 hours brought an explosion of the confused talk about the irreversibility of quantum mechanics (and especially the measurements in it).

Well, people have posted lots of other crazy stuff about quantum mechanics. For example, the dog with many phase-shifted legs above, one created by the Czech 3D artist in London, Mr Ondřej Zunka, is surely totally cool. But the idea that this animation has anything to do with the way how our quantum mechanical Universe works is dumb beyond imagination. Quantum mechanics doesn't add many new legs to the dogs. Quantum mechanics just makes the uncertainty about the existing legs more unavoidable and adds some new causal relationships between the properties and their uncertainties.

### American patriots, Second Amendment fans should celebrate the purchase of Colt by CZG

I must start with the proud disclaimer that I hold some stocks in CZG, the Czech Armory (Česká zbrojovka Group), a position that I doubled on Thursday.

Here is a monologue by a man who thinks that the operation (which was officially announced as completed on Thursday night, some stamps from regulators are waiting) is good news. So first, Colt is a legend, especially in Czechia.

### Czech state of emergency should be over from Monday

On Thursday, I spent at least 5 hours by listening to the Czech Parliament (the lower house) which discussed the government request to extend the state of emergency again (the current one has been in place since late September). The state of emergency isn't quite the same thing as a lockdown; but they are closely related because the state of emergency is a legal framework that allows the government to do potentially harmful things that it simply cannot do otherwise, at least not without very special ad hoc justifications. They include the closure of all non-essential shops in an area. Our non-essential shops are closed now (although they were opened in December for weeks) and even some supermarkets are not allowed to sell non-essential goods (I couldn't clearly see the difference, however, the rules must be confusing).

Communists whose votes are needed to keep the minority government (coalition of ANO i.e. the billionaire PM Babiš and the social democrats) in power already had doubts about the extensions of the state of emergency in the past. They often succeeded in reducing the duration of the extension but it didn't matter because the state of emergency was later extended again, anyway. Now they helped to cancel it which finally could matter. Only ANO and social democrats want to continue. Other lawmakers have adopted the prevailing view of the Czech public that it is just too heavy a weapon that doesn't really bring much of an improvement in anything. The government hasn't been able to refine its policies so that the people would feel that the policies help more than they harm.

### PandaX-II seems to slightly strengthen XENON1T's hints of dark matter particles

The recent Chinese 3D remake of the legendary cute Czech Little Mole features a new, bigger friend of the Central and Eastern Europe, I mean of the little mole, namely the People's Republic of China, I mean a big fat panda. ;-) This was the first episode among many.

This blog post is very brief because I don't think it's a good investment of time to write full-blown texts. But as you know, the hints of any new particle behind the Standard Model are extremely weak or almost non-existent.

Last June, Elena Aprile and her XENON1T folks (yes, one ton of xenon in the detector) saw some

Excess Electronic Recoil Events in XENON1T
(not to be confused with nuclear recoil events that they also like to observe) which represented the excess around 3.0-3.5 sigma above the background.

### French public, elites will fight cancel culture

The demagogy and terror spread by the unhinged new leftists is often presented as an inevitable trend. They are so strong and they will win everything, I often hear from people who otherwise pretend to be my allies. With such "allies", who needs enemies? The actual fact is that the fans of cancel culture are intrinsically super-weak, worthless, easy-to-suppress stinky worms and if you consider these worms your "unavoidable future overlords", it is because you are an even weaker, more pathetic, collaborationist pile of manure. Your weakness and collaborationism may be a greater problem than the worms themselves, especially if you allow me to count tens fo millions of snowflakes like you.

In the wake of the woke scum's contamination of the universities in the U.S. and similar enough institutions in similar enough countries, these collaborationists often claim that it is equally unavoidable that this lying poison will also take over all of Europe and many other places. Oh, really? Two days ago, Satoši Nakamoto wrote an interesting text for the New York Times about the moods in France:

Will American Ideas Tear France Apart? Some of Its Leaders Think So
French politicians and academics are largely dismissing the pathologies or an "intellectual matrix" (the words of the French education minister) that are being "entirely imported" from the U.S. and that threaten France. Emmanuel Macron, the president who has tried to maintain his "centrist" image and didn't discuss these important questions in the past, said that the woke garbage from the U.S. universities "ethnicizes the social question and breaks the republic in two".

### Why civilization owes everything to capitalism: a lesson of a new subject

I spent about five more hours on the phone with someone whom I understand rather well. But when I heard that all the landlords are parasites, all rents are excessive, and people have the human right in live in their real estate, well, I saw that the understanding has some limits.

It seems to me that schools should be teaching some kind of economic and financial literacy – and especially the basics of capitalism, what it means, and why it statistically directs mankind in the optimum direction. Such a subject could be combined with history.

### A screenshot of Android apps, widgets

This is an extremely simple and unimportant blog post: 7 commented screenshots of screens with apps and widgets on my tablet, Huawei MemoPad M5.

Nevertheless, I believe that simple "real life" blog posts are rare on the web.

Incidentally, it is an amazing tablet with a great display, thin and formidable metallic construction, impressive audio, fast and reliable fingerprint reader, good enough battery, fast charging etc. I haven't turned it off for 18 months and it's doing great. The Amazon URL goes to a 10-inch one, I have a smaller one.

### Fat tails of sub-freezing temperatures

For a decade, since the freezing winters 2008-2011 or so, the chilly weather and deep snow has been relatively rare in Czechia – e.g. here in Pilsen. Well, it's different now. After the safely above-the-normal rainy weather 2020 that ended the ludicrous fearmongering about the once-in-500-years drought (see the maps at Interdrought.cz; even one meter of soil is saturated with water almost everywhere now), we also enjoy a standard old-fashioned white winter.

People are cross-country skiing in Pilsen and downtown Prague. Yes, the links offer you skiers on the Charles Bridge, Old Town Square (this photo of the mayor of Prague over there is pretty cool, indeed), and kids bobsleding near the Prague Castle (the minister of interior claims that the Petřín Slopes aren't slopes and cops may collect up to $500, oh, really? I hope they won't try to fine Borat.). ## Friday, February 05, 2021 ... // ### JT supergravity and SYK described as type 0B strings One of the themes that string theorists and string-like theorists recently spent time with is the JT (Jackiw-Teitelboim) supergravity. It's some gravitational theory in 2 spacetime dimensions. Well, there aren't too many gravitons and other things propagating in such a low spacetime dimension. But you may calculate $$Z(\beta)$$, a partition sum. I consider this theme a "microrevolution" because it doesn't quite reach the threshold of excitement for a minirevolution. This JT supergravity, a 2D dilaton gravity, has been linked to the Sachdev-Ye-Kitaev (SYK, random magnets) 1D quantum mechanical model which is pretty much a holographic description ("CFT") for this quantum gravitational theory. OK, such "apparently non-stringy" quantum theories of gravity are always risky. The low spacetime dimension means that many of the methods and principles that operate in realistic quantum gravity in 4-11 spacetime dimensions may become invalid. Nevertheless, it is a highly justified position to assume that all truly consistent theories of quantum gravity should be a part of string/M-theory. Is that true for the JT supergravity? ## Monday, February 01, 2021 ... // ### Edwin Steiner's video about "plus" in between the wave functions Many of you know Edwin Steiner. He sent me the following video that he has recorded about quantum mechanics, about the "plus" in quantum mechanics, in between terms in the Hilbert space (i.e. a video about the "superpositions"). After years of his smart comments, I am confident that he understands the universal postulates (and rules) of quantum mechanics and a quick review confirms that. Well, he does say that the "plus" means "OR" (just like in the probability distributions), not "AND", as many popular books like to erroneously say. I would have preferred if we dedicated more time to the physical relevance of the relative phases between the terms (which is a way to describe the main difference between the classical and quantum case). ### Shortsellers are neither evil nor mathematically impossible And if you weren't a brainwashed imbecile, you would occasionally be a shortseller, too The GameStop mania is a religious movement involving millions of staggering and overwhelmingly young idiots who believe that * shortsellers are extremely evil and to fight them, you have to sacrifice everything * they are doing something that doesn't even mathematically make sense * by panic buying a shorted stock for a price that is overstated by a factor of 10-1,000, all the participants are going to make astronomical profits This kind of stupidity just leaves me utterly speechless (by the way, I am instantly banning every commenter who shows any inclination to believe either of these amazing propositions because interactions with creatures who are this dumb simply terrify me and I won't allow the comment sections to become unfiltered cesspools). The situation is probably even worse than it seems. According to a Harvard College Consulting Group research, 31% of U.S. "investors" below 24 want to make a "quick cash" (I immediately imagine the "lawyer" from Idiocracy who said that he liked money) and about the same percentage (around 30%) use Reddit as a recommendation what to do. The number of registered users of WallStreetBets sub-Reddit grew from 3 million to 7.7 million in a week but a much larger number of people follow the forum without any registration. ## Saturday, January 30, 2021 ... // ### Czechia had fewer deaths in 2020 than in 1990 By 0.1%-0.3% from the truly absolute numbers + 0.3% from the extra day of a leap year + 0.4% from the population growth Up to a moment in October 2020, I tended to believe that Czechia (and many other countries) wouldn't see a significant increase in the total number of deaths per year (2020). It became clear to me when the first self-evidently elevated numbers from late September 2020 were coming out at this web page of the Czech Statistical Office (and especially in this table; you should download an updated version of the "tab" file if you read this text after January 2021). Suddenly, it was clear that the deaths with Covid were mostly real extra deaths due to Covid, indeed. The graph is taken from this page of the Czech Statistical Office where I picked the maximum interval 1814-2019. The year 2020 will add a death dot at the level of the 1990 death dot. Imagine that I spent 5 minutes by editing the picture above. The worst weeks of 2020 brought us ~4,200 deaths instead of 2,100 deaths which is normal in a week, a true doubling. Surrounding months saw 3,000 per week or so, the increase by 50 percent or so. ## Friday, January 29, 2021 ... // ### Energy conservation holds in quantum mechanics Sometimes (and increasingly often), totally wrong and dumb papers are accepted by arXiv.org. An example is a quant-ph paper Energy Non-Conservation in Quantum Mechanics by Sean M. Carroll and Jackie Lodman which should have prevented the authors from passing the most elementary undergraduate course of quantum mechanics but it didn't. Instead, we live in the era when the mass media are intensely misinforming and indoctrinating the readers so you may read a promotion of this pseudoscience at the moderately widely read blog of the male co-author. OK, they claim that the only meaningful conservation of energy in quantum mechanics is the conservation of the expectation value of the Hamiltonian; that this is violated; that this violation can be arbitrarily large; that this violation cannot be attributed to the energy of the observer or the apparatus; and that the "many-worlds interpretation" makes all these questions more controllable. Each of the five statements is absolutely and fundamentally wrong. ## Thursday, January 28, 2021 ... // ### GameStop: the steps that deflated the bubble are even more outrageous than the bubble itself I didn't expect Wild West financial market trading of masses to be a flavor of the first weeks of the new far left regime in the U.S. However, as I described in the previous blog post, "anti-shortseller activists" at Reddit WallStreetBets have targeted several stocks and drove their prices to insane levels. They included mainly GME, AMC, NOK, BB, and BBBY. Nokia is the only one in the list whose current price remained close to the widely perceived intrinsic value; BlackBerry is second. The rest are just insane bubbles created by the kids who put their life savings whatever the price is, just like what they have done with Tesla and Bitcoin. GameStop Corp, a network of outdated videotape and game media shops in the dirty passages, became the most important target of the group. The stock price was a bit below$20 on the first days of 2021; some hedge funds thought it was still too much. If you click at the hyperlink in this paragraph, you will see the incredible growth up to $470 earlier today (the price doubled in a day and it has done so many times). Because the company has 70 million shares, the two numbers translate to$1.4 billion and $33 billion, respectively. Yes, by capitalization, the GameStop company became a bit bigger than Nokia itself. Well, it is no longer the case. ## Tuesday, January 26, 2021 ... // ### WallStreetBets Reddit & Robinhood: a herd distorting the markets Even a broken herd may be right about once a decade I have been aware of the insane Tesla and Bitcoin (and other cryptocurrencies) bubbles which show how (mostly) the Millennial generation makes the markets – or at least the price discovery – dysfunctional. But those are just the most extreme tips of an iceberg. This new culture of hyper-conformist obedient sheep that are tied to the social media has an effect on many other corners of the financial markets. Well, sometimes the effect may be healthy and push the prices towards fairer values (but I believe that it is mostly a coincidence when it is so). For some time, I have been aware of the Robinhood trading platform. I didn't pay much attention to it. It looked like another platform – why should it matter what you use to trade your stocks and options? You should register at robinhood.com and download the app there (Robinhood may be found in the app store). There are alternatives (such as Webull, also search) but it seems that "virtually everyone" who belongs to the sheep culture simply must use Robinhood. ## Sunday, January 24, 2021 ... // ### Petr Kellner's transactions look like pure, clever, and ethical capitalism to me Petr Kellner is the wealthiest Czech. A Forbes list shows his current net worth as CZK 293 billion (USD 1 = CZK 21.5 now; so it is$13.6 billion). The following four men, Vítek, Křetínský, Babiš (the prime minister), and Komárek, only have CZK 86-71 billion.

Kellner became his convincing journey towards being an almost crown billionaire soon after the Velvet Revolution when he founded some PPF funds that participated in the voucher privatization (only 11th by size at that time). By now, he has lots of assets in Russia and China (he probably wants to exit the latter because it's not really safe), especially the global Home Credit company. In Czechia, by now, he has acquired either 100% stakes or majorities in the O2 big telecommunication company, Cetin the telecom infrastructure, Air Bank, Home Credit CZ and SK, Czech Pojišťovna Insurance (with Generali), CETV with the largest commercial TV NOVA, Škoda Transportation making trams and trains here in Pilsen, a CZK 0.25 billion horse for his daughter that Bill Gates couldn't afford, and lots and lots of other things (in his PPF Group).

### Why should we be afraid of the new Joe Biden Administration?

By 2nd President of the Czech Republic Václav Klaus

The unexpected, violent, albeit totally chaotic, disorganized, planning nothing and signalling nothing incursion of the Trump supporters (but also all other groups that love any attack against the official institutions, regardless of their ideological underpinnings) into the U.S. Capitol has diplaced all the serious and highly desirable debate about the new president. Biden has been successfully "promoted" to a position that cannot be debated and cannot be criticized and this promotion was an amazing move, whether it was preplanned or it just exploited the events a posteriori.
