What to do right before the end of the world

The apocalyptic mood at many places has been predicted in many science-fiction movies. My most favorite one is Sexmission (Poland 1983). (Cheeky) Max and (shy) Albert volunteer in a hibernation experiment by Prof Kuppelweiser in 1991. Instead of 1994, they are woken up in 2042 in a society led by the League of Women. Kupperweiser has also invented a special bomb that has destroyed the male genes.

Kuppelweiser must have worked for the Wu-Chan Institute of Virology because, as Parravicini pointed out, Covid-19 may damage kidneys and testicles. The feminist ideology rules in that strange society (but much more relaxed than the SJWs today!) that lives, as we learn soon, under the ground. The ladies are told that the Earth's surface is uninhabitable which is a sophisticated lie designed by Her Excellency (who ultimately turns out to be the sole male survivor) to control the women more easily – that theme was a successful prediction of the global warming hysteria.

Calculation of particle masses without string theory is implausible

...or any comparably deep advance in fundamental physics...

Anna V has mentioned a seemingly interesting March 10th Greek talk about a paper that claims to calculate the elementary particle masses with 1% precision out of some gravitational attraction between objects matching the ideas of a schoolkid at an elementary school.

Off-topic, experiment: the gravitational force has been measured down to 50 microns (the distance between the two masses), Newton may relax, he is still OK.

Usefulness of colliders outside HEP: accelerators' superconducting RF cavities may be helpful to build quantum computers. Also, quantum information theorists talk to quantum gravitists about wormholes which is right although I don't quite understand what's the new insight here
The paper is childish nonsense, of course. You can't answer difficult questions like that with the elementary school algebra (and ideas). The authors have obviously not understood the difficulty of the problem – which is not far from the completion of a theory of everything – even at some vague qualitative level. To derive particle masses, you almost surely need to use the Standard Model gauge group, the representation theory for the particles, non-diagonal mass matrices and their eigenvalues, and probably also the renormalization group running, aside from many other hard components. It's almost guaranteed that very simple formulae with the 1% precision can't exist and even if the final low-energy masses could be given by a miraculously simple formula, you can't possibly derive or justify such a formula from some understanding of particle physics which seems absent in the paper.

As far as I can see, the authors haven't even understood the vast range that the masses span i.e. the hierarchy. They're described by various hierarchies, including the hierarchies in the Yukawa couplings and, in their case, also the standard hierarchy between the weak scale and the Planck scale (which they claim to use). And even a qualitative answer to the question "why those parameters seem so vastly different" seems extremely difficult.

The hierarchy problem has been studied by a huge fraction of theoretical particle physicists for half a century, they have used a lot of ideas and difficult tools, and there's no "clearly winning" solution to explain the hierarchy, not even qualitatively. Would you really believe that some elementary formula written down by Greeks suddenly answers these questions? Then you're a gullible victim of anti-scientific populism. Trivial formulae for hard problems could be nice for you but they're wrong – or it's impossible for them to be right.

Not even omnipresent seasonal Covid-19 is a rational justification to dramatically change our behavior

China has almost certainly tamed down the infection. The most recent 24 hours show 32 new Chinese fatalities plus 435 new cases. The latter number is almost matched by South Korea, the #2 country sporting the illness, which saw 334 new cases (and one fatality) in recent 24 hours. The remaining countries combined saw just 19 fatalities yesterday. Note that about 150,000 people die in the world every day.

South Korea already has almost the same total percentage of population infected as China (1600 infections in Korea, 78,000 in China, the ratio is about 50 while the population ratio is 27) and a higher percentage of new people infected per day than China during the peak.

The suppression of the Chinese disease is a reflection of the draconian measures taken in China. Whoever says that they are not draconian simply belongs to China or another dictatorial country, not the Western civilization. Clearly, South Korea is more democratic so the taming of the disease, if possible, can't be this fast.

Covid-19 probably peaked in early February

From Monday on, the world markets have seen a new giga-hysterical reaction to a dozen of coronavirus deaths in Italy (out of 300 or so cases there), a reaction that has already exceeded 9/11 (if you add nearby days that probably have the same reason). If you don't remember, the U.S. markets were closed for a week after 9/11, lost 7% on the first day, and recovered within one month.

Meanwhile, the main Covid-19 statistics page shows a dramatic reduction in the new cases and deaths. When we started to cover this story in early 2020, I mentioned that the "doubling time" was comparable to two days or so. Well, we're surely not getting one doubling per day; the actual numbers suggest it is just one doubling after half a year assuming the current rates. Instead, the fresh data show:

80,997 cases in total
...=...48,090 active cases
...-...=...39,251 mild
...-...+...8,839 severe
...+...32,907 closed cases
...-...=...30,143 cured
...-...+...2,764 dead
You can see that the number of cured people has surpassed 30,000, not surprising after a month. At the beginning, the number of cured people was about the same as the number of fatalities. Then the cured people grew a lot and trumped the severe active cases. Within a week, the cured people will surpass all active cases, including the mild ones.

Classical, realist theories just fail to produce unitary gadgets

Nature, quantum mechanics organize gadgets along complex matrices; realism doesn't

In 1925, after 15-25 years of searches in the dark when all the good physicists knew that a radical change of the foundations of physics was urgently needed, physics switched to the quantum mechanical underpinnings. Those are totally and obviously different than classical physics – although they may produce classical physics as a limit – and it's unsurprising that virtually every complex enough experiment is predicted to end up differently by quantum mechanics than by any classical theory.

The difference was nevertheless made explicit in many toy examples starting with Bell's theorem. Bell's theorem studies various types of measurements made on two qubits. It's a straightforward situation – pretty much the simplest situation in which some entanglement exists – and one may calculate the prediction made by a general classical local theory with hidden variables. It produces results that obey some general inequalities and indeed, those inequalities are violated by quantum mechanical predictions as well as observations (the latter two agree).

Old "Miss Germany 2020" is deceitful

The post-modern left-wing NPCs are fighting against everything that the Western civilization has been built upon and that has been admired for hundreds or thousands of years – Christian and European values, nation states, freedom, democracy, private ownership, roles of men and women, the scientific method, meritocracy etc. – and it is unsurprising that the women's beauty is a target, too.

Some of the beauty contests have come under attack in some Anglo-Saxon countries and swimsuits have been erased.

Germans constantly want to retake the crown for the most unhinged left-wing nation in the realm previously known as the West which is why they have demolished the main beauty contest, too. A 35-year-old mom, Leonie von Hase, was allowed to run – she was obviously the oldest contestant in the contest ever, since the 1920s (18-39 years was the allowed age range) – and she was chosen Miss Germany 2020 by a women-only committee.

EU may dissolve due to clashes about modest sums of money

Exemptions for net recipients from Gr@tin, similar harassment campaigns would be better than redistribution

Many of us are partly living in the virtual, exciting, and tense world created by the media, blogs, and the extreme discussion in which psychopaths seem to be several months from imposing Islam and banning carbon in the world, among other things. Meanwhile, the real world – and lives of ordinary enough people – continues to operate along less extreme lines. Instead of a Big Clash of Civilizations, mass conversion of tens of millions of people to the opposite sex, or the heretical status of carbon, the European Union may very well dissolve... because of a few petty billion dollars.

Net recipients and net payers to the EU budget a few years ago

The U.K. has happily left the European Union and it seems that it will be capable of avoiding the old payments to the EU, indeed. The U.K. has been paying below €9 billion to the EU budget annually, less than half a percent of its GDP (try to appreciate how tiny their percentage of the GDP sent to the EU budget relatively was – if you compare it with the relative importance of the EU in the political discussions in the U.K.). It's been a net payer, the second largest one (well) below Germany and (well) above France and Italy.

The incredible shrinking expertise in Brian Greene's books

Brian Greene has released and is promoting his fifth full-blown book for the popular audiences, Until the End of Time. I read the table of contents, a few extra pages, reviews, and summaries of some talks. I feel totally disillusioned by the trend.

You know, the first book, The Elegant Universe (which I enthusiastically translated to Czech, like The Hidden Reality, the third book; The Fabric of Cosmos #2 was left to my friend who has a name day today), contained a legitimate explanation of the relativity of simultaneity, presentation how the ultraviolet catastrophe was solved by the light quanta, why the spacetime has to be curved to communicate the gravitational force, topological expansion of string theory, T-duality, mirror symmetry, its application on the counting of spheres in a quintic, and much much more.

EU: Václav Klaus' prophetic talk 11 years ago

Today, it's 2020/02/20 but let us look 11 years, 1 day, and 1 hour to the past when Czech president Václav Klaus gave a speech in the European Union's Parliament (Czech video):

Speech of the President of the Czech Republic Václav Klaus in the European Parliament (English transcript)
I encourage you to read all those 20+ paragraphs. The fundamental problems with the European Union look self-evident to all the sane people today but it wasn't always like that and in 2009, almost everybody – including most of us, I think – viewed Klaus' warnings as remote.

Petr Macinka (IVK) has picked some statements from the speech.

Leftism, Marxism really are mental disorders

Sometime in 2013, Ann Coulter famously said that liberalism is on the spectrum of mental illness. Well, this was surely not the first time when a similar quote emerged. In 2010, Michael Savage released the book Liberalism Is a Mental Disorder.

Those statements might sound like memes or insults. The only problem is that they're not only memes and insults. They're also approximations of cold hard facts.

Slate Star Codex has organized a survey involving 8043 participants and investigating links between the formal mental diagnoses and the self-identified political beliefs of the people. Slate Star Codex is proud about the survey, it just finds it heretical for others to report the results or to link to them – so I won't do that. Instead, let me link to nicely reviewed stories

Sickness to Socialism: Leftists Are More Likely to Have Mental Problems, Survey Shows (The New American)

Survey Finds People Who Identify as Left-Wing More Likely to Have Been Diagnosed With a Mental Illness (Summit News, Paul Joseph Watson)
All the numbers below divide the people mentally to those who have been formally diagnosed at least with one of four disorders; and those who haven't. The four disorders are depression, borderline personality disorder, bipolar disorder, and schizophrenia.

Jeff Bezos throws away $10 billion of his money fund organized crime based on pseudoscience...

Last night, the media informed us about a shocking decision that was greeted by arrogant titles in far left outlets such as

Billionaire Jeff Bezos Figures He Might as Well Try to Help the Planet He Currently Lives On
He will never live on any other planet. The suggestion in the title is fake news and pure arrogance. He said:
Climate change is the biggest threat to our planet.
What a staggering moron. There is no climate-related threat to our planet, let alone a big one. Instead, the actual threat to mankind – not to planet – are active morons ("aktivní blbec" has been used in Czech at least for 50 years), psychologically ill Scandinavian spoiled brats, and children who were left behind and who are "capable" of saying breathtakingly stupid sentences such as the quote above.

Dawkins vs Molyneux on eugenics

On Sunday, Richard Dawkins posted this tweet that many expected to lead to his absolute, immediate, and hysterical cancellation:

Yes, Dawkins wrote that "eugenics works" which just doesn't mean that it's a right policy to introduce. Needless to say, as a sane and honest biologist, he has to write it: humans are just another species of mammals and breeding and similar things (including genetic engineering) surely work for the other mammals, so it must work for humans, too.

A cute Czech bank robbery in Switzerland

Chur, Switzerland

Lots of events around us are full of violence, existential threats, and hatred. On Thursday, Chur, a town in Southeastern Switzerland, had the opportunity to see the advantages of criminals imported from Czechia over those from the Middle East and other regions:

A Czech robbed a bank and ordered a beer (DE)

Bank robber owes me six francs (DE)
A 55-year-old Czech man came to the main hall of a Cantonese bank, Graubündner Kantonalbank, on the Poststrasse 2. He drew a starting pistol and shot in the air twice, carefully avoiding the people.

RIH Pachauri: 1940-2020

The sad death of many people who have been great to mankind and who have contributed something remarkable is a part of the decay of our civilization. The generations of achievers, sometimes modest and constantly smiling and self-sacrificing achievers, are being replaced by the generations of frowning spoiled brats that whine about microaggressions and stolen childhoods while on their intercontinental yacht trips that are paid by someone else.

Well, statistics makes exceptions unavoidable. On Thursday, February 13th, the 79-year-old Rajendra Pachauri ceased to live due to his long-term heart problems. He was an Indian railwayman, a sexual pervert, and one of the most notorious fraudsters in the world who has also led the IPCC panel promoting the climate change alarmist scheme.

Rot In Hell, monster.

Position, momentum modulo a grid may be measured simultaneously

Spiros leaked a trivial observation from a talk given by John Preskill: in quantum mechanics, the position and the momentum may be measured totally accurately and simultaneously, but only modulo \(\Delta X\) and \(h / \Delta X\), respectively.

The proof is a simple application of the CBH-like formulae such as\[

\exp(A) \exp(B) = \exp(B) \exp(A) \exp([A,B])

\] whenever \([A,B]\) is a \(c\)-number. And indeed, it is the case if \(A,B\) are linear in \(x,p\), respectively. The precise position \(X\) modulo \(\Delta X\) may be expressed by the (unitary) operator\[

\exp(A)=\exp(2\pi i X / \Delta X)

\] while the analogous momentum \(P\) modulo the inverse spacing \(\Delta P = 2\pi \hbar / \Delta X\) is expressed as\[

\exp(B) = \exp(i P \Delta X/\hbar)

\] Nice. So apply the CBH formula to get\[

\exp(A)\exp(B) = \exp(B)\exp(A) \exp([A,B])

\] to see that the commutator appearing as the last exponent is \([A,B]=-2\pi i\) and, as you know, its exponential is therefore one. If you choose units with \(\hbar=1\) and a dimensionless \(X,P\), you may democratically pick the spacing \(\Delta X =\Delta P = \sqrt{2 \pi}\), as announced in the original tweet.

Bojowald: Ashtekar school is fundamentally misguided

Hat tip to @mmanuF at Twitter

Martin Bojowald has been a well-known name in the loop quantum gravity corners and especially in loop quantum cosmology. Aside from other things, while he was working at the Max Planck Institute in Potsdam, he co-authored three papers with Abhay Ashtekar, a guru of loop quantum gravity, in 2003, 2005, 2005.

Amusingly enough, now, when Bojowald and Ashtekar are colleagues at Penn State, he just released a gr-qc paper

Critical evaluation of common claims in loop quantum cosmology
that tries to critically look at some basic aspects of the "Ashtekar school", as he calls it. Bojowald concludes that the Astehkar school fails in all of his nontrivial tests. It makes assumptions about the semiclassical behavior of the metric tensor degrees of freedom while the semiclassical approximation is almost certainly inapplicable in these examples. Also, Bojowald points out that characteristically quantum mechanical effects – such as ambiguities resulting from quantization – are incorrectly assumed not to exist.

Needless to say, loop quantum gravity people may be classified as full-blown or generalized anti-quantum zealots – people who actually think classically and who misunderstand everything in which the classical limit fails to be "basically right".

Mad commie Sanders: a good reason to evacuate the U.S.

A great PC game for free: Kingdom Come Deliverance (EG page), an amazing 55-gigabyte 2018 Czech game about stories of Henry, a son of a blacksmith (in Rataje nad Sázavou, Bohemia, Holy Roman Empire), in 1403 AD (see Wikipedia), will be available up to Feb 20th for free (it went live on 5 pm today, Czech Winter Time, or here now) through the EG site. See a trailer and Amazon or YouTube. The creator-in-chief is Dan Vávra, a brilliant and politically sensible guy who also masterminded the famous Mafia 1 and 2. You need a good enough gaming PC with 8 GB or more and perhaps to download the EpicGames' platform first, too. Hat tip for the game, 2018: Crabik-Manzo

Viruses: A fascinating article on the Quanta Magazine about HIV and especially narnaviruses whose RNA may be read backwards and makes some sense, a very rare property. The curious people such as you and me immediately ask "why". The leading hypothesis is that they want the host to read the RNA backwards and think that it's meaningful but harmless – but the right reading is in the first direction in which it is meaningful and harmful, and the host gets fooled. ;-) Like people don't suspect that A Beers Dinners is dangerous but it is one of the 11796 anagrams of Bernie Sanders, a toxic thing.
On one hand, Bernard Sanders (I find the affectionate form of the first name crazy to be applied to a hardcore Bolshevik apparatchik) was a victim of the Democratic Party establishment. They probably stole the 2016 nomination from him and they were trying to do the same now. On the other hand, the Democrats' worries are understandable and by now, they're probably accepting the fact that he is a rather likely candidate to win the nomination.

Moderates such as Joe Biden aren't too moderate. On top of that, Biden is incoherent and his whole family should spend their lives in a prison for the corruption in Ukraine (and probably elsewhere). However, all these personal things are details relatively to what can change the United States of America and the most dramatic changes are associated with the name of Bernard Sanders.

Even with Enyaq, electric cars make no economic sense

In the morning, we learned that the Eurozone's industrial production has dropped by 4.1% year-on-year. It's clearly one of the manifestations of the devastating impact of the neo-Marxist Luddites who took over the bureaus of the undemocratic transnational institution known as the EU.

Herr Bernhard Meier, the boss of Škoda, the second highest-margin brand in the Volkswagen Group, started to call for help. Spreading their medieval superstitions about the weather, the unhinged Luddites really want to destroy the car industry of the old continent.

Trudeau runs Gestapo that secretly bullies, go after the neck of opposition

Peter F. sent me a totally shocking video with 470,000 views (and 99% upvotes) that was published by Rebel News Network, the main Canadian right-wing TV platform, on January 29th:

HIDDEN CAMERA: Police interrogated me about my Justin Trudeau book. They didn’t know I videotaped it
Ezra Levant published a book on Trudeau's corruption during the October 2019 elections in which Trudeau got 40%. The book made it to #2 at Amazon.

He was summoned to the capital, Ottawa, because of some complaint related to the book. The 26-minute-long video shows that the cops, apparently highly paid cops who previously fought terrorists etc., refused to tell Ezra Levant, the boss of Rebel News Network and the main co-author of the book, what the complaint or accusation was.

Socialist "fighters against socialism" fail to see the important things

William Barr has proposed a sensible, cheap solution to remove the dangerous gap in the 5G mobile data technologies where China is 1 year ahead of Europe and 5-10 years ahead of the U.S.: just invest several tens of billions into Nokia and/or Ericsson, and elevate the indirect strategic control of the U.S. companies but also the U.S. government over these industries. Make sure that the abundant U.S. cash is being poured into these technologies so that the gap is disappearing.

Some clueless ideological hecklers have immediately greeted the sane proposal by Barr, a long-time Telecom companies' lawyer, with the insult: "It is socialism". Because I've been saying the same things as Barr for months, my ideas were labeled equally. I find these comments totally clueless and indeed, very analogous to the screaming "Don't touch Facebook, Twitter, and other private companies, they have the right to ban anyone".

Nazi German lawmakers plan to imprison all Euroskeptics for 3 years

...and/or make them pay dearly...

Much like in the 1930s, freedom has been largely exterminated in Germany again but what we learned today (thanks, Prof Konvička and Counterstream) is perhaps even more shocking than most of the previous events. Several small German outlets have just superficially mentioned a shocking new addition to the German criminal code (Strafgesetzbuch, StGB) in progress, namely § 90c StGB, that wants to outlaw any criticisms of the European Union involving its symbols. This initiative has been discussed at the level of a "law of the state of Saxony" since 2018.

My understanding is that even e-mails with this playful satirical picture would be outlawed in Germany.

The Bundestag has already discussed this addition in the first reading in mid January 2020 and the documentation was prepared in October 2019:

Drucksache 19/14378
The proposed form of the new paragraph § 90c is written on Page 5 (in German). The two parts say:

Criminal code is extended by § 90c, Defamation of the EU symbols
  • Who publicly, during an assembly, or by spreading a written document defames the EU flag or the EU anthem, will be punished by a prison term up to 3 years, or a financial fine
  • The same punishment waits for everyone who removes, destroys, damages, publicly abuses, makes unusable, or publicly humiliates the EU flag. Even an attempt to do so is punishable.
Wow. It is just staggering. But yes, I still laughed when I read the verbs in the second verse. They reminded me of a scene from a Czech fairy-tale, "There Is No Fun With Devils", where the officer says "He is a rebel! When he was being arrested, he seriously injured three soldiers, bruised two soldiers, and... he humiliated another one!"

Barr's right, the U.S. should buy 51% of Nokia and Ericsson

The U.S. Attorney General William Barr gets it and has finally articulated the same proposal that I have been promoting for several months (e.g. in this tweet one month ago):

The U.S. government, with or without a help of the U.S. private companies, should acquire a majority stake in Nokia, Ericsson, or both, and become a major player (and, in a few years perhaps, the #1 player) in the 5G mobile data industry because it will be a vitally important part of the economy that also gives the providers quite some influence and China – with its otherwise dominating Huawei provider of the 5G hardware – poses certain risks for the U.S. and its allies.

Mike Pence and the chairman of the FCC Ajit Pai have already declined to support the proposal, offering a non-solution instead, but that refusal may be just a maneuver to cover imminent plans to buy the stocks.

Can holography in the flat space be made manifest?

The last hep-th preprint today was written by the colaboration consisting of Brahma, Vishnu, and Shiva:

The Holographic Nature of Null Infinity.
OK, the actual names are Laddha, Prabhu, Raju, and Shivastava but I was pretty close. They courageously claim that you don't need to study anti de Sitter spaces and beyond-QFT effects to establish holography. You may see holography in the flat space and the general relativity quantized in the naive way, too.

Consensus vs Czech rate hike

Bloomberg posted this amusing map of the world:

Countries with central banks are divided to three groups: those that haven't made a decision in 2020 yet (grey), those that kept rates (yellow), and those that lowered the interest rates (cyan).

And then there is a fourth group, a league of their own, the Czech National Bank (pink). It raised the discount, two-week repo, lombard rates to 1.25, 2.25, 3.25 percent, respectively, all by 0.25%, today at 2 pm Prague time. (The middle, repo rate is crucial to determine commercial interest rates.) The announcement was delayed by 1 hour – either because they wanted to lower the shock or because they needed an extra hour for wrestling.

Iowa caucus glitches wonderfully show why leftism is dysfunctional

KOTO kaon anomaly: just some links, a fresh Science News review of a September 2019 talk by Satoshi Shinohara (PDF). They saw four long-lived kaons decaying to neutral pions plus missing energy, instead of a fraction of an event. It's probably noise but you may look at some theorists' proposals to explain it with light scalars, leptoquarks, new sources of CP violation, and more.
Iowa started with the caucuses on Monday. Caucuses are similar to primaries – elections to choose the nominee of a party – but people vote publicly, after they loudly persuade each other to move to one side or another side of a gym. Similar caucuses have taken place for some 250 years in the U.S. but it suddenly failed. It's Wednesday and the partial result from 62% of districts (not necessarily representative ones) are the best thing we have (the number jumped to 71% before I completed this blog post).

We are really used to final results 2-3 hours after the Czech elections end.

Ellen Feiss, a stoned Democratic organizer, tried to report the results from her district

This event has quickly become the world's second most notorious technological screwup of the recent 40 years after the Chernobyl accident. Both accidents show why it is utterly insane for millions of people to allow leftists to decide about the public affairs. I can tell you: "been there". Well, we've lived under communism for 41 years so all these events in Iowa look extremely familiar to me.

ČEZ seems serious about small nuclear reactors

ČEZ (Czech Energy Works) is the dominant Czech power utility. The company has the capitalization €10 billion now (CZK 503 per stock), 60% of which is state-owned. It operates some power plants and business in many other countries, too. If you're a fan, you should check the virtual tours into numerous power plants of ČEZ – nuclear, hydro, and the Long Slopes (Dlouhé Stráně) hydro "battery".

It produces most of the Czech electricity – Czechia is a net exporter. About 1/3 of the electricity is made by 2000 MWe in Temelín, South Bohemia (divided to two reactors), plus 2000 MWe in Dukovany, South Moravia (divided to four reactors). If you want to follow the reactors and wait for the explosion, check the ČEZ website.

When dumb humanities trainees deform education

In the morning, Europeans learned that the number of dead and cured Covid-19 coronavirus patients grew to 361 and 475 or so, respectively. The second, "recovered", figure starts to clearly dominate. It may become even rosier in coming days when the HIV+flu drugs improve the treatment of the patients.

The London attacker was an ISIS fanatic who wanted his GF to behead her parents, who has done some planning of terror attacks in the past, who was arrested, who shouldn't have been freed again, but who was freed prematurely instead (deja vu). Within days, he went to stab the people. What a surprise. In a society that encourages murderous scum, the murderous scum feels encouraged (Sky News called the terrorist a Gentleman, cool).

In a Quora digest, the following question stimulated my interests and raised my adrenaline level even more, however:

Why do so many Americans insist that “anyone can learn mathematics” when the available evidence strongly suggests otherwise?
A fair enough question. The answer is that these Americans are either stupid and misunderstand mathematics themselves – and they actually say that everyone has enough brain power to misunderstand mathematics as much as they do – or they do understand mathematics but they are politically correct liars who build their well-being on similar "everyone can do everything" lies.

Among the 50 answers, the most successful one is the answer by Jean Rafenski Reynolds. It has some 200k views and 2k upvotes and it's annoying, indeed.

Soros: Zuck has replaced Putin as Trump's co-devil

Can Zuckerberg become a champion of freedom and civilized values?

After Katie Hopkins, Twitter banned another major account: that of, a mainstream Libertarian financial server. It happened shortly after ZH published some breaking news and results of investigative work about the possible man-made role in the origin of the coronavirus causing the Covid-19 illness.

An Indian preprint claims that there are "uncanny similarities" between the coronavirus and two types of the HIV virus – suggesting that some Chinese (perhaps with some passive Canadian help, we read elsewhere) researchers did something deliberately harmful. You know that I've considered the "bioweapon" explanation as a possibility since Day One but I am somewhat unimpressed by this paper. The sequences that agree are rather short and may occur accidentally (especially because not all sequences of a given length are equally likely). The HIV has 10,000 bases but many variations exist. Also, "uncanny similarity" is the kind of loaded, non-quantitative language addressed to the laymen that raises red flags from my viewpoint. Why isn't the probability of an accident like that quantified in the title or close to it?

On the other hand, there are really many reports that the HIV+flu cure does cure the coronavirus as well which is... really interesting (and optimistic). But even if HIV were present at the birth of the coronavirus, it doesn't quite imply that genetical engineers were involved. Also, even if they were involved, it doesn't imply that the coronavirus is a serious disease.

At any rate, I think it is essential that the free debate about these questions – even because they're important questions and especially because they're important questions – exists (the accusation against the Chinese man may be unfair but it may also be true and important, even for the health of nations) so the ban of on Twitter is absolutely unacceptable. The formal justification was "harassment" of a Chinese scientist who may be involved with a similar research. Note that it wasn't the Chinese authorities but a U.S. media cesspool that demanded the punishment for – the same aggressive cesspool that harassed the 14-year-old political scientist and de facto distinguished professor Soph last May.

Left-wing lunacy spreads because people were led to forget that negative numbers exist

The U.K. is no longer formally an EU member. Millions of aßlickers of the EU were waiting for the British islands to sink into the ocean last night and the naughty islands shockingly failed to do so!

The ongoing discussions about the coronavirus-caused Covid-19 disease have reminded about a very general thesis of mine about the reasons behind the proliferation of left-wing lies, lunacies, and hysteria and the disappearance of critical thinking in general. My thesis is that the character of the discussions, newspaper articles, TV segments, and curricula at schools have led a huge number of people to forget about the negative numbers.

Effectively, a huge fraction of the people makes the assumption\[

\forall x \in \RR, \quad x\geq 0

\] in most of their "thinking" about the real-world problems. The general problem is this simple! Note that the known records of negative numbers first appeared some 200 years before Christ in... China, indeed... under the Han Dynasty. In the 7th century India, negative numbers were practically used for debts. An everyday drill emphasizing the naturalness of a concept probably does a lot of work to make the concept acceptable.
