Lies about mandatory mathematics from math haters

As expected three weeks ago, yesterday, the Czech government abolished the plans to introduce a mandatory "matura" exam (at the end of the high school) from mathematics since 2021. The parties in the government clearly want to steal some of the lazy stupid brainwashed young voters from the Pirates, a party of far left green drug addicts and Antifa puppets. The status quo will continue – the teenagers may choose an additional foreign language or mathematics and almost all of them, and an increasing majority, simply choose the language.

It's very bad, some voices of sanity are heard on the Internet but they're accompanied by the brain-dead SJWs and math haters who celebrate. The tweet above is from Mr Jan Skopeček, a conservative lawmaker whom I know in person. He says that mathematics should enjoy some respect, especially in an industrial country like ours. It cultivates the thinking and the mandatory exam may increase the quality of the high school education. He will vote against the plan in the Parliament.

Karl Popper, the spiritual father of George Soros

...and unlimited mass migration, unlimited censorship, and instantaneous destruction of profound research by "falsifiability" chants

Many of us consider George Soros to be the ultimate personified evil in the contemporary world. Yesterday, I watched a dozen of videos by the Little Brother whom I hadn't known before and who looks like a rather brilliant Czech counterpart of some of the best Anglo-Saxon conservative or classically liberal YouTubers.

One of these videos was This is George Soros and it is a rather friendly portrait of the billionaire – at least given the fact that the Little Brother "stands on the other side of the barricade".

OK, we learn that Soros was born as Schwartz in a rich Jewish family in Hungary. His father was an esperantist and lawyer, was able to get some documents to turn the family into a Christian Soros family, and they moved to the West. In New York, young Soros thrived in the banks, traded European stocks, and was generally a decent trader doing his work.

An incredibly upbeat U.N. speech by Greta Thunberg

Greta Thunberg is Swedish and many of you only speak English. Finally, the English translation of the remarkable U.N. speech by Greta Thunberg has gotten to you, distinguished TRF readers – through the positive Czech translation as the intermediate step. I think that you will agree that Czech must be a beautiful language. Enjoy!

0:00 [During a climate conference, Greta Thunberg gave a surprisingly optimistic speech in the halls of the United Nations in New York. It is such groundbreaking news that fills me with so much optimism that you should allow me a simultaneous translation of her ideas. Let's go ahead.]
0:23 I bring you the news that we are watching you carefully.
0:36 Everything smells of an unprecedented optimism.
0:42 I shouldn't be up here.
0:48 I should be back in school, on the other side of the ocean.
0:58 It's fantastic that you also allow the young people to speak. Thank you for that.
1:02 You are realizing the dreams of my childhood by your wonderful acts.
1:17 I am undoubtedly one of the happiest children in the world.
1:26 The poverty on the planet is decreasing at a miraculous rate. The vaccination against the worst diseases has reached amazing levels.
1:39 The life on our planet has never been thriving so much.
1:48 We are at the beginning of the most peaceful and safest epoch in the Planet Earth's history.
2:00 And all of it is thanks to your relentless trade and the cooperation in diplomacy and research that shows that the era of the world wars belongs to the past.
2:12 You rock.
2:30 For more than 30 years, we are witnessing an unprecedented scientific and technological progress.
2:35 How did you achieve that?
2:43 For me to come here and to criticize you would be an immensely hypocritical thing to do.
2:52 When solutions for most of the global problems have already been searched for and built for decades.
2:58 You say that you will keep on working hard.
3:03 And that it is urgent.
3:08 But in spite of all of that...
3:13 I can't believe that we could ask you for even more.
3:27 I know that you understand the situation very well, much more than I do. Look, I am still just a high school student.
3:37 But I believe that after long years of studies and diligent work, I will once become as productive a member of the society as you are today.
4:00 Fifty percent of the African children who, after decades of vigorous efforts by the whole planet, finally escaped the famines and malaria and found themselves in the world where they don't have to spend their lives by the struggle to survive but they may also enjoy some comfort much like the comfort that we in Sweden have been enjoying for many decades.
4:39 Fifty percent of children could look acceptable to you but it would be very hypocritical for us to place an upper bound on such children by regulations. The rich person doesn't believe the hungry one, a proverb says, which is why I urge you to let the African and Asian children to determine their own fate.
5:05 Billions of tons of CO2 produced by the Western countries cannot become an excuse to truncate the progress of the third world exactly at the moment when our technologies finally allow us to eradicate hunger and poverty once and for all. [Unseen, unseen.]
5:30 But fifty percent of children simply isn't enough. We want the progress to continue at the highest possible rate and we want the world to end up as a place that is full of prosperity and happy faces.
5:48 I recommend you to keep on caring about your business and ignore the pressure coming from the alarmists who simply despite the human control over Nature.
6:06 Those utterly fudged numbers allegedly describing the amount of CO2 that we're still allowed to emit shouldn't be taken seriously because they boil down to completely shaky hypotheses and to a wishful thinking.
6:37 Let us be mature and agree that our priority should be a fight against poverty, diseases, temptation to start wars, and the technological progress that is not interrupted by anything and that will ultimately allow us to excel under any climate change scenarios.
6:59 You have created an unbelievably prosperous, safe, and friendly future for us and the young people are extraordinarily grateful for that.
7:12 All of the future generations will be building on your work.
7:20 We will never forget about the millions of human lives that your cooperation has saved.
7:39 We will not let you down.
7:45 We want you to enjoy beautiful years of retirement while our generation will continue in your work to make our planet flourish.
7:55 The world is beautiful and it is full of life.
8:02 Fuck the polar bears.
8:17 [Beautiful. I was touched. Have a nice day. Your little brother.]

This simultaneous translation is one month old. The little brother, Ondřej Tesárek, was just vaporized from Facebook a few days ago.

By the way, he is a classical liberal with lots of videos. I was touched by this one:

Freedom is no longer cool

I was born right after the Velvet Revolution when my homeland could finally breath again. For fourty years, it was surrounded by the Iron Curtain... [He says how the people were shocked by the freedom of the 1990s when they had to swim, so they returned, abandoned creativity, restored jealousy, and started to live much like during communism.]

Why Czechs "still" celebrate Czechoslovakia after 101 years

Czechia celebrates the most important national holiday today and Barefoot Backpacker posted a question that surely looks silly to Czechs but I have seen it many times, especially when asked by Americans:

Why the hell do Czechs celebrate the birth of Czechoslovakia if that country, albeit peacefully, ceased to exist at the end of 1992? You know, after 10 years in the U.S., I sort of acquired some empathy for the "completely different way of thinking about nations" that is mainstream in the U.S. although I surely haven't acquired the different thinking itself.

Prof Thomas Garrigue Masaryk, Czechoslovakia's president-founder

So I understand that given some kind of education and discourse about the meaning of the words "nation", "country", and "state", it's a damn good question why we frantically celebrate the anniversary of a country that's been gone since 1993! ;-)

What is more incomplete: Copenhagen or many worlds?

In the first stage of the Einstein-Bohr debates, Einstein tried to prove that quantum mechanics was wrong – literally producing predictions that conflicted with observations. When he was persuaded that this goal was just plain stupid around 1930, Einstein switched to the second stage in which he "only" argued that quantum mechanics (as defined in Copenhagen) was "incomplete".

Even today, almost 90 years later, the anti-quantum zealots who are still around – depending on the degree of their stupidity – argue that quantum mechanics is either wrong or incomplete. The typical complaint that "quantum mechanics isn't complete" is formulated as follows:

But the Copenhagen Interpretation fails to tell us what is really going on before we look.
Well, in reality, quantum mechanics tells us everything that is happening before the observation: nothing that could be considered a fact is happening before (or in the absence of) an observation! It is an answer. You may dislike it but it's a lie to say that you weren't given an answer!

Girl: feminists in social services enabled the suicide+murder of my younger sisters by our mother

One week ago, James Younger's reproductive organs and his dignity were threatened when a Dallas jury voted 11-to-1 to allow the non-biological mother of the 7-year-old boy (who has an identical twin brother, Judy) to eliminate the biological father Jeffrey Younger from the boy's life and continue with the "transition" of James into "Luna", a girl. The woman's plan was that aside from the "social transition" that was already ongoing, the hormonal castration would start at age of 11.5.

A video showing a 3-year-old James makes it clear that the idea that "he was a girl" was imposed on him by the woman – by a silly kind of manipulation that is sufficient to affect children.

On Thursday, perhaps under the pressure from the public and maybe also the governor of Texas who had launched an investigation, the judge ruled (despite her being left-wing) that both parents would continue in the joint custody, the father may veto such medical procedures, and both parents must be silent about the matters. The incredible vote by the jury was partly caused by some child service (CPS) bureaucrats and their "testimonies". That institute is apparently full of radical feminists and trans-sexual activists.

These wrong people at the wrong places are existentially dangerous. They may kill. Sadly, something that looks like a proof appeared in a tragic story in Northern Bohemia on Friday i.e. three days ago.

Czech entomologist on ecology, climate panic

PL Jakub Vosáhlo's interview with Dr Martin Konvička, an entomologist and the president of the Czech Islamic Republic

Assoc Prof Martin Konvička as you don't know him (he's primarily famous as a warrior against Islam): in recent years, Nature was primarily demolished by the EU climate policies, irresponsible charlatanry involving the climate, and mad experiments with the landscape.

AN INTERVIEW: After his activity addressing the migration and the clash of civilizations, Martin Konvička recently talked about the fashionable war on the climate change. And he clearly has something to say about the issue as an Associate Professor of biology and a respected expert, especially in science of insects (and yes, butterflies). He unmasks some devil's glitches with the ongoing campaign to plant trees or the risk of the forced transition to the "green" technologies. In the interview for the, he also hints at the reasons why so many scientists, often questionable scientists, jumped on the climate research bandwagon in recent years.

Some fun with a proof of the Riemann Hypothesis

A few days ago, Tatenda Kubalalika, a young mathematician in Harare, Zimbabwe, directed my attention to his ambitious paper

Prime numbers and the Riemann hypothesis
To make the story short, I spent about 5 hours over the period of 30 hours before I became sufficiently certain that the paper cannot contain a valid proof of the most prominent open problem of mathematics. Of course I mostly agree with those who say that the Riemann Hypothesis (RH) is very difficult and elementary-looking proofs are almost certainly wrong.

On the other hand, there's no rigorous proof of that assertion – and it's hard to imagine such a rigorous proof of that no-go theorem because you can't even define "elementary-looking". So when someone is excited and passes some tests of not doing something "entirely silly and wrong", I just pay attention. Of course it's been a waste of time so far (dozens of the most famous mathematicians since the 19th century have wasted a lot of their precious time, too) but there's some probability that it could work.

So I am interested not just in my ideas about the RH but also about ideas of others.

7 reasons why identity politics warriors are toxic

A prolific science writer at Forbes has argued that everyone should become a fanatical feminist, reverse racist, and passionate multi-genderist in fields with a majority of white straight cis-sexual men:

6 Steps Everyone Can Take To Become An Ally In White, Male-Dominated Workplaces
The claims are breathtakingly dishonest and radical in their desire to ruin the last traces of meritocracy and the basic glue that holds the human society together. His 6 basic rules are actually 7 – as an URM (that's a new great acronym for underrepresented minorities that he probably wants us to use! So I will use this slur, be my guest), he probably doesn't know the small integers too well.

Using my words, these 7 steps say:
  • 0: Always place attention to PC above the work in your field
  • 1: Always prefer a discussion about the PC ideology over the discussion about your work
  • 2: Respect double standards, always treat URMs as both superior people and victims, and don't ever dare to compare URM with regular mortals such as you
  • 3: To be fair, be unfair because if you were fair, it would be unfair (this is a real beauty)
  • 4: Train yourself to feel guilty all the time
  • 5: Hysterically scream at everyone who says something non-PC
  • 6: Always do more affirmative action and distort the system more than others expect
Pretty disturbing, indeed. Without the context and experience, I would think that this article is a parody trying to point out how insanely dishonest and destructive the champions of PC are. But I know enough to be nearly certain that this text at Forbes was meant seriously.

SaveJames: why jury voted 11-to-1 shows why PC trash took over the West

Despite her being rather, ehm, progressive, the Texas judge ruled yesterday that both parents will share the custody of the twin brothers – Judy and James Younger. They will also co-decide about medical issues. What happens if they disagree? Unless the dominant interpretation on the Internet is wrong, the father will be able to veto any castration-like procedures.

So it's as big a win for James' testicles as we could hope for. Relatively to that, the gag order against the father – he also needs to erase the website etc. – looks like a detail.

It's entirely possible that the investigation of the case by the Texas governor that was launched shortly before the verdict "helped" the judge to disagree with the jury.

Even men have their periods

Another day, another advance by the transsexual overlords.

Protector & Gamble, the cosmetics giant whose Gillette department thinks that men who need to shave are toxic, has been asked by the transsexual activists to remove the symbol from the menstruation products. The result?

Always to stop using Venus symbol on menstruation products to be more inclusive (Google News)
Procter & Gamble told the transsexual activists that they were so honest, kind, tolerant, reasonable, healthy, pretty, fertile and all great companies in the world must obey their orders. So the Venus symbol (♀, an egg anchored to soil by a cross) will be removed because, you know, some of the users of the menstruation products would prefer the Mars symbol (or the Earth twisting with Jupiter and Saturn into a giant circle) – I guess it's the people born as women who convinced themselves that they are men and hexadecimal-non-binary-X-mxn etc. although I am frankly no longer certain that I use logic correctly to determine even these basic answers (this very confusion is a major goal, of course).

Dallas jury encourages woman to castrate a 7-year-old boy who isn't her biological son

Your humble correspondent and virtually all my compatriots who have heard the news from Texas yesterday just cannot believe it:

Jury rules against dad trying to save his 7-year-old from gender ‘transition’

...Google News...
Dr. Anne Georgulas, a child physician (this occupation itself is absolutely shocking given the story below), has claimed to be the mother of James Younger (7) and also asserted that James wants to become a girl, Luna, so she wants to start to hormonally castrate the boy. She asked a Dallas court to attack the father of the boy, Mr Jeffrey Younger (in the process of divorce with Ms Georgulas), who wants to prevent the "transition", who uses the name James to call his son, and who says that the son is OK with being a boy.

Dallas Rainbow Therapy is expected to cripple the little boy soon

Stunningly, the jury ruled in favor of the would-be mother; the vote was a stunning 11-to-1. The father isn't allowed to call James by his legal given name – you know, "James" – and he can't take him anywhere where he could be referred to as a boy! And the mother may start to destroy the boy's reproductive organs!

Theories with special properties are more valuable, more likely than generic cousins

In an interesting conversation, someone complained about the recently published numerous new swampland constraints by saying that they "go too far".

While I don't know whether these constraints are valid, I believe that the complaint that a scientific hypothesis "goes too far" simply isn't a valid scientific argument – and it is downright harmful. Why? Because those of us who like science and progress in science actually want the new theories to be as far-reaching as possible – we just want the new results to go very far! The idea that they "shouldn't go too far" is equivalent to saying that the speaker "doesn't want much progress in physics"!

If some hypothesis "goes too far" in the sense that its proposition is too strong, it should be easier, and not harder, to disprove it – assuming that the statement is indeed wrong. When it's so, we should be more demanding and indeed expect an actual disproof and not just some emotional or prejudiced complaints that something "goes too far", right?

Green Nazis effectively fired Dr Crockford (polar bears)

This is just a short linker-not-thinker story. We may be approaching the "Lidice 1942" moment of this conflict. Nazi Germany was growing in self-confidence and area up to mid 1942 or so – and suddenly the trend got reversed.

It's impossible to completely attribute the peak to an event but I choose the Lidice massacre in June 1942 – the first act of genocide that the Nazis bragged about (village eradicated and flattened because of untrue rumors about its responsibility for the assassination of Heydrich) – to be the event that has reversed the sign of the trend.

Soon afterwards, the U.K. revoked its signature under the Munich Treaty and all the Allies on the edge started to take the anti-Nazi fight seriously. While presenting Greta Thunberg as an authority, the environmentalist extremists may have jumped the shark – and if they haven't, it's one of the other acts they are doing these days that may be classified in this way.

Demagogic puzzles involving randomness, quantum mechanics

Pradeek Mutalik is a "puzzle columnist" in the Quanta Magazine. Readers are usually invited to solve some problems or puzzles. But they're not "just puzzles". They're always claimed to have implications for the fundamental laws of physics. This latest one is

How Randomness Can Arise From Determinism
and it is clearly presented as "puzzles that help the reader think about quantum mechanics".

The only conversation under this video is: Frederick Mush: It's fraud. - Sazka Corp: Why should it be? - Because I don't see a notary and I don't win much when I guess three numbers right.

After all, the word "quantum" appears in the first sentence and 6 other places in his article (and 18 times on the HTML page now). The only problem is that everything that the reader "learns" about randomness in quantum mechanics is completely wrong.

In effect, Mutalik's "puzzles" are an excellent example of the omnipresent demagogy and misinformation in the "mainstream" media that makes the readers of such media increasingly deluded and scientifically illiterate.

Letwin amendment: a dirty, silly trick to make Brexit politics meaningless

I have watched the British House for several hours again. PM Boris Johnson has impressed me – with his clear enough ideas, politeness, and consensus building. He wanted the MPs to approve his Brexit deal – which looks much better for both sides than what I thought possible just a month ago.

Sadly, Oliver Letwin submitted an "amendment" which actually implies than any real vote about a Brexit deal is delayed up to the moment when the legislation is complete. Because of this new delay – caused entirely by the British MPs in this case – one has to pay attention to the September 2019 Benn Act.

Squeezing amino acids from comets order to create life...

Just a short comment. Yesterday, the Astrobiology Magazine discussed a paper that will be heavily promoted in the coming issue of Chemical Science,

Synthesis of functionalized nitrogen-containing polycyclic aromatic hydrocarbons and other prebiotic compounds in impacting glycine solutions
by Rebecca Lindsey and 2 men from LLNL. (I chose the middle author because the name is both female and easy to pronounce. That's how it works today, sorry, Gentlemen.) They used some nice quantum quantum chemistry approaches to argue that comets could have been helpful for the birth of life on Earth.

Top IPCC's paleoclimatologist agrees that Mann's hockey-stick papers were wrong

Two days ago, Tom Nelson (via Willie Soon) informed us about some juicy revelation:

Note that the tweet also includes a link to a McIntyre audio on Watts' blog.

According to an influential IPCC official, McIntyre and McKitrick were right in their criticism of the papers by Michael Mann et al. – the so-called hockey stick reconstruction of the global mean temperature.

Primitive communism is mostly a myth

As schoolkids in the communist 1980s, we were taught that the human society has evolved from the primitive communism to slavery, feudalism, capitalism and its later stage, imperialism, to socialism – which we were just enjoying – before we would arrive at communism. To avoid misunderstandings, our countries were officially "socialist" countries while "communism" was the money-free nutty utopia where you may "do whatever you like to do and take whatever you want". ;-) The last stage hasn't worked too well so far although, especially in recent years, many brainwashed people want to restore this sickly fantasy about the future.

But I want to focus on the first stage, the primitive communism. The meme was coined by Marx and greatly elaborated upon by Friedrich Engels, the Thunberg-like spoiled brat from a wealthy family who decided to rebrand a stinky lazy homeless vagabond Karl Marx as an intellectual. In the German original, the regime was called Urkommunismus – it is the same Ur as in Pilsner Urquell (The Primordial Source [of Golden Transparent Beer] from Pilsen) – and for some reasons, we use a very different term

prvobytně pospolná společnost
in Czech which sounds contrived, self-explanatory, a bit poetic, and non-ideological. It roughly translates as the "primordially-settled together-ish society". I would like to know the details but I guess that the first translator of Marx's and Engels' rants to Czech decided it was a great idea to replace the ideological word revolving around "communism" with a non-ideological one. It may speed up the propagation of the meme in the anti-ideological Czech nation, he may have believed. Well, it has worked for me.

Czech PM: expansion of nuclear energy stands above the EU law from our viewpoint

PM Babiš has earned some positive points from me recently – by his at least partly critical attitude to Greta, to some new mass migration proposals, and by his dropping from the 2nd wealthiest Czech citizen to the 4th place (I am a compassionate conservative). But today, he got some new points for nuclear energy.

Ironically, as I have previously mentioned, this year of Gr@tinism – which would produce a lot of support for nuclear energy if there were at least some rationality in this movement – has been accompanied by a new anti-nuclear wave, too.

The eyes on Temelín's cooling towers were real (in 2018) and became the largest videomapping in Czechia so far (the Prague Astronomical Clock videomapping was surely much more sophisticated, however). And they were created by Mr Milan Cajs, the drummer of Tata Bojs. Not bad.

Aside from the climate hysteria, we are constantly bombarded by anti-nuclear propaganda, too. A month ago, Reuters hyped a "study" saying that nuclear energy was too slow and too expensive to save the climate. Cool!

Political prisoners in Germany and Spain

While the post-communist part of Europe behaves sanely these days, Western Europe is split and a big part of it has been devoured by novel political movements that want to totally destroy all the opposition, everyone who disagrees with them, and they are ready to use the worst possible tools.

Germany is currently led by a hardcore ecofascist government that wants to punish the German citizens even for their very disagreement with ecofascism. A driver has decorated his car in this way. The pigtails are nicely hanging from that car and the author of the idea wisely and generously recommended a young Scandinavian political leader to "fudge off, Greta" and he rightfully bragged that the climate change "problem [was therefore] solved".

What is the reaction by the ecofascist Merkel government? Three years in prison for that driver. The driver has just expressed his opinion about an extremely troubling political movement that is contaminating much of Europe and North America these days. The pigtails are clearly just a symbol of the unhinged ecofascism we are seeing everywhere around us. That particular spoiled brat wasn't in any way threatened by that driver.

Drought left Czechia, no apologies heard

Like most other places, Czechia has seen some drier periods and some humid ones. The latest "big flood" took place in 2002. Recent five years were relatively dry.

This is what the drought conditions looked like yesterday, on a beautiful sunny Sunday October 13th, according to (Interdrought). Almost everything is white – no risk of drought. On that website, you may choose Czechia, Slovakia, or Europe; and the interval to play the evolving dry places as an animation.

Governor of North France demands a war budget against the political Islam

In my country and elsewhere, it's taken for granted that countries like France have already been lost and their drift towards becoming Islamic republics is unstoppable and irreversible. Well, I am an optimist who happens to think it's far from clear.

Le Point published some explosive pronouncements by Xavier Bertrand, a former Republican and the governor of Hauts-de-France, the Northernmost province of France with 6 million people.

Equalities are the most vital equivalences

The equal sign is innocent, it doesn't prevent us from studying some very abstract geometric structures

A few days ago, Kevin Hartnett wrote a provoking article about mathematics for the Quanta Magazine,

With Category Theory, Mathematics Escapes From Equality
If you think that some mathematicians finally fight against the left-wing egalitarianism and its worshiping of equality, well, the truth is somewhat less optimistic. ;-)

The human hero of the story is Jacob Lurie, a mathematician who recently moved from Harvard to IAS Princeton. I do believe that he is an extremely good mathematician – also because of his classifications of topological field theories, research into exceptional groups, and more. But the Quanta Magazine article is about Lurie's somewhat idiosyncratic hobby, namely his holy war against the equal sign.

There shouldn't be any equalities like \(2+2=4\), the article argues. Instead, all equalities should be loosened to equivalencies, like in category theory, which are better because equivalences come in many flavors and degrees. And the original category theory of Eilenberg and MacLane (1945) wasn't loose enough which is why we need to switch to "infinity categories" and Lurie's articles that are some 8,000 pages long in total.

Fermion masses from a Δ(54) heterotic orbifold

Stephen King, the King of Horror, didn't receive the Nobel prize in literature for his 200 short stories yesterday – the award went to Austria and Poland instead. Similarly, neither Trump nor the aggressive Swedish teenager got the Nobel prize in peace today – instead, it actually went to a guy (prime minister) who established peace in Ethiopia. ;-) Clearly, the committee in Oslo needed and still needs to recover some credibility after it was overspent in recent years.

But Stephen King (I guess it is a different one) is the most famous author name of an exciting 4-author hep-ph preprint today

Flavon alignments from orbifolding: \(SU(5) \times SU(3)\) model with \({\mathbb T}^6/\Delta(54)\)
The masses of quarks and leptons are free and arbitrary parameters in the Standard Model and one of the most obvious collections of data that expects to be explained by a deeper theory – some SUSY/GUT or ideally string theory.

It's clear why the number of Earth-like planets is so imprecise

...because the term is neither quantitatively well-defined nor useful...

Two weeks ago, Ethan Siegel more or less defined the scientific method as the mindless obedience to Greta Thunberg (combined with the mandatory anti-quantum-mechanics crackpottery). I thought it wasn't the right definition and virtually everything he wrote was upside down.

One week ago, he wrote a text

Astronomers Debate: How Many Habitable Planets Does Each Sun-Like Star Have?
which highlights his mathematical illiteracy and the mathematical illiteracy of several astronomers – and the wisdom of Michael Crichton. To make the story short, the astronomers agree about the interpretation of the Kepler data but they still have a very uncertain estimate about the number of Earth-like planet per Sun-like star – the estimates go from 0.013 and 1.24. And it's very surprising, Siegel wrote.

Well, for those of us who always knew that science wasn't a mindless worshiping of someone or something by words from a human language, it's not surprising at all.

When accusations of "groupthink" and "collection of likes" become ludicrous

If you want to understand what they mean by psychological projection...

Abraham (Avi) Loeb, the Israeli American chairman of astronomers at Harvard, has gotten some reasonably good press on this website. However, no sane person may doubt that he is a media-savvy or political flavor of a scientist whose visibility in the media overstates his contributions to physics – a field he actually loves to discuss loudly.

In recent years, the readers and viewers of the mainstream media have heard about him often because he has co-authored numerous wrong, silly, or vacuous preprints that were really professionally formatted troll's diatribes against physics, inflationary cosmology, and other things – and inkspillers in the popular science media (and millions of their stupid brainwashed readers and viewers) simply love this kind of pseudoscientific trash. That's why I laughed so much when someone sent me his October 8th essay in the SciAm blogs

Science Is Not about Getting More “Likes”:
Extraordinary groupthink leads to extraordinary ignorance
Both the title and the subtitle are combative yet true. However, in combination with the name of the author, these three lines are hilariously funny, indeed. And he's not a darling of the left-wing media just because he loves to repeat bitter, misguided remarks about the very value of physics and cosmology which are too speculative according to Loeb. He's also a darling of the popular media because he's a boss of an organization looking for extraterrestrial aliens. Physics is too speculative for him but ETs around us are not! Cool.

Mapping Calabi-Yau threefolds by the degenerated representatives

The chemistry Nobel prize goes to the de facto invention of lithium-ion batteries. It's not a terribly huge advance in pure science but as applied science, it's been literally game-changing, of course. Although Czechia has a top European reservoir of lithium, I do hope that we will switch to lithium-free batteries at some point.

The first hep-th paper today is
Classifying Calabi-Yau threefolds using infinite distance limits
by Grimm and two co-authors (NL/CH/UK) that elaborates on a nice and clever way to map the landscape of the Calabi-Yau threefolds. Their excitement is seen on the fact that they worked hard enough to post the preprint at the top – it was posted 3 seconds after the new day started.

They look at special points in the landscape of these 6-real-dimensional manifolds that may be very useful for "navigation" in that landscape – at the degeneration limits.

Peebles & exoplanets share the 2019 Nobel prize in physics

I watched the press conference at which the 2019 Nobel prize in physics was announced. The announcement started at 11:50 am Central European Summer Time (which is also our time here).

It's ironic that some common sense and meritocracy that we used to know comes from... Sweden. The first good sign was that the Nobel committee hasn't removed the dude wall yet. And the Nobel committee room at the Royal Swedish Academy of Sciences has quite a dude wall, indeed. After all, even Alfred Nobel has failed to undergo the sex-changing surgery in memorian so far.

Denmark wants to ban "carbon" car sales in the EU by 2040

Nowadays, and especially in the recent year, lots of people – especially in geographically Western Europe and in North America – are saying extremely crazy things about the energy, climate, fossil fuels, and the future of mankind in general. One particular proposal made by a whole EU country in recent days may deserve a special discussion: Denmark wants to kill cars (Euractiv, Financial Post).

More precisely, by 2040 – and some sources say similar sentences with 2030 and 2050 (it seems they don't care about the difference) – the whole European Union should ban the sales of all petrol and diesel cars. Cool!

Receipt lottery: how to save 10,000 hours of Czech lives a day

Some $2 million worth of time savings per month

The EET, the online realtime verification of all cash payments in Czechia to fight tax evasion, has been repeatedly criticized on this blog because it was an extra burden for the businesses and self-employed people, a sign of arrogance of the government (and of the employees towards to the economically independent folks), a risk of abuse of the data, and for other reasons.

But by now, the system – that hasn't provably reduced the tax evasion according to the data – is a part of reality and Czechs including your humble correspondent are adaptable beings. I am not even 100% sure whether it would make sense to abolish this new piece of bureaucracy now. Well, if I could, I would probably still make it optional, while telling everybody that the people using EET have a lower risk of an audit.

An hour ago, I received a surprisingly sensible response from the Czech finance minister Ms Dr Schillerová – about my proposal to improve the "EET lottery".

Someone bought butter for CZK 25 ($1.1), eggs for CZK 45.50, and CZK 70.50 was rounded to CZK 71. One crown is exactly strong enough to make the payments in integer amounts of crowns "sufficiently fine and accurate yet easy to compute with and remember". She got a receipt including the cumbersome hexadecimal BKP and FIK codes; you know, butter and eggs are basically rocket sciences.

You know, the EET works as follows. Whenever a consumer pays cash to an entrepreneur or shop anywhere in Czechia, the business is obliged to print a receipt and immediately send an electronic copy of the receipt to the finance ministry. The receipt must include the cash amount that was paid (and that will have to be taxed, that is the point), some ID of the business, date, time (HH:MM), and a long hexadecimal code BKP that may be influenced by the computer owned by the business.

The finance ministry's computer responds that it was received and produces another, quasi-random code FIK that is sent back to the business, so that the receipt may ideally be printed including the FIK code. In most cases, it is. In some situations, the registration may be delayed etc. and there are some receipts without a FIK code.

Czech teenagers protested against mathematics

High school students in other countries are obsessed with the climate hysteria. Their Czech counterparts managed to organize about one lukewarm rally in March – these days, they had a much more urgent problem: to fight against the "matura" from mathematics. See a video from their rally on Friday afternoon.

All Czech high schools where students are expected to go to a college – in particular, the liberal arts "gymnasiums" and "lyceums" as well as the commercial-sector or engineering-focused "industrial schools" – are ended with this "test of maturity".

The arrows show a building of the Math-Phys department of the Charles University (maps).

It's a pre-college test that verifies and, if the outcome is good, certifies that the student – who is between 18 and 19 at that time – isn't stupid and may be compatible with a large number of occupations including ones that require some intelligence and knowledge. The subjects have been evolving in time. As you may imagine, mathematics has been a mandatory subject throughout the history because it's the queen of sciences and thinking. My 1992 "maturita" (the most official Czech name) was from Czech, English, mathematics, and physics – physics was optional, I think. A century earlier, Greek and Latin may have been widespread subjects in the exam.

At some moment years ago, after the fall of communism, the mathematics exam was made optional. As the students were increasingly turning into a shallow, vacuous, bullšiting SJW herd of sheep, from an intellectual viewpoint, mathematics was becoming an increasingly unpopular outlier or an exception (among other subjects where it was increasingly sufficient for success to simply babble some ideologically convenient nonsense) and increasingly impossible for them to learn. So the number of the people who were choosing it – instead of a foreign language etc. – was persistently dropping.

I am scared of innocent children

By Václav Vlk Sr, translated and endorsed by LM

All of us know Andersen's fairy-tale about the king who was walking naked – before an innocent child exclaimed: "The emperor has no clothes." This fairy-tale may be interpreted by saying that the citizens of the kingdom knew that the king was naked but they were forgiving him because he was an otherwise good king and the citizens weren't stupid (see e.g. the top Czech 19th century writer Karel Havlíček Borovský and his King Lávra) but the moral story in which an "innocent" child revealed a "terrible truth" is popular, and that is why it was also used by a man whom I have known for decades as a fellow lover of science-fiction, Mr Jaroslav Veis, in his article "Who is afraid of Greta" on September 30th. In effect, his text was just another moralizing and intellectual exercise on the theme "how we, Greta's fans, are moral while you, her foes, are a gang of morons and demagogues".

60 °C of global warming: tens of millions would survive just fine

The scientifically illiterate pundits often tell us that with a few more tenths of a Celsius degree of warming, the human race will face extinction. To show how open-minded and deep thinkers they are, they sometimes discuss whether you need 1.5 °C or 2.0 °C of warming relatively to the 18th century to make the human race extinct. Maybe the global mean temperature at 15.5 °C won't kill all of us yet but 16.0 °C surely will! ;-)

I have previously mentioned that my best estimate for the global warming at which the probability of human extinction were around 50% is about 200 °C of warming. (A Gr@tin claiming to be a skeptic has quickly cursed me for my blasphemy.) With this dramatic figure, mankind would have to be extremely original, disciplined, technologically advanced to invent tricks to deal with the situation and it would start to be unclear whether it's possible at all.

So I wanted to write a blog post about "millions that would surely survive 100 °C of global warming". One hundred is such a nice rounded number. That was a result of my quick thought. When thinking about the details, I ran into the problem caused by those boiling seas - you know, 30+100 = 130 °C is above the boiling point of water.

After some refinements, I decided that the validity of the statement in the planned title would depend on the details – the devil is often in the details. Whether the warming would be really uniform across the globe, whether the temperature would be measured right above the ocean or elsewhere, and many dynamical questions about the co-existence of the evaporated oceans near the tropics and the surviving liquid oceans near the poles.

I actually think it is a very complex homework exercise for students of atmospheric and oceanic physics. Good luck with that. Where would be the precipitation in such a half-evaporated, half-liquid ocean world? And so on. To make the problem really well-defined, try to describe the climate zones of the current Earth that is simply moved to Venus' or another warmer orbit, for example.

SF6: how unknown greenhouse gas may almost match, maybe trump the known one

Many people have completely lost their mind. The time for discussions and rational thinking has ended, they say, and now it's the right time to mindlessly listen to mentally disordered teenagers and to panic. Well, the fact that it is implausible for the climate change to cause global problems, at least in the following centuries, doesn't matter for them.

In reality, we known many examples of extra CO2 emissions that are caused "somewhere in the process", at a slightly less visible place – the production of batteries or electric cars, wind turbines, the tractors moving over the fields while producing biofuels, and many more.

Matt Ridley has pointed out this great new example related to the wind energy – SF6; click for a BBC story. Sulfur hexafluoride. I can't resist to brag that we call it "fluorid sírový" in our superior Czech chemical terminology. The suffix in the adjective "-ový/-ová" (the same one we add to create female surnames) actually contains the "hexa" information (we have different suffixes for the other oxidation states 1-8 which are called the "oxidation number" in Czech), "síra" is sulfur. Wouldn't it be cleverer if oxides of carbon weren't monoxides, dioxides etc. but rather carbonic, carbonish, carboneque, carbonian, carboner, carbonest, carbonisian, and carbonician oxides, or whatever suffixes the English linguists would invent instead?

Greta didn't advance in "Got Talent": it's jury's fault

This isn't a very important blog post, I just wanted to allow viewers to watch the video and read the subtitles simultaneously. Well, Greta "Tumberk" Thunberg who is just 16 has amazed the jury – especially its blonde member – by her recitation.

0:00 Man-right: Good evening
0:01 Brunette: Good evening (silently)
0:05 Greta: Eh-uh
0:07 Blonde: Did you register for this talent contest yourself?
0:10 Greta: [silence]
0:13 Man-left: Uhm. Who is working as your manager?
0:15 Greta: [silence]
0:18 Man-left: What's your occupation? How do you make living?
0:20 Greta: Human control
0:21 Man-right: Yes!
0:23 Blonde: That is beautiful! Yes!
0:25 Brunette: Finally!
0:27 [Applause]
0:34 Man-left: You know exactly how things should be, I like it.
0:35 Man-right: The stage is yours.
0:39 Greta: My message is that we will be watching you.
0:41 Man-left: You're the first contestant this year who has totally arranged it all in her head.
0:44 Greta: You have stolen my dreams, my childhood with your empty words. You say you hear us and that you understand the urgency.
0:55 Jury: Haha [appreciating the power]
0:56 Greta: But no matter how sad and angry I am, I do not want to believe that.
1:01 Blonde: This was the most beautiful moment for me.
1:03 Brunette: We need everybody to be like this. So that she would always smile and everyone would be so happy.
1:04 Greta: [hateful frown]
1:06 Man-left: You are simply a pure soul.
1:09 Greta: Thank you.
1:11 [Jury presses "fail" buttons]
1:12 Greta: Evil.
1:13 [Jury: More "fail" buttons]
1:15 Greta: How dare you!?
1:18 Man-right: I like when the 16-year-old ones have their own opinion and they pursue it. And your text made sense. You have a future and a potential.
1:28 Blonde: My brain has been erased.
1:29 Brunette: No, I am very happy that I saw it. I am really grateful.
1:32 Man-left: This non-self-confidence?
1:33 Brunette: Yes but the ultimate one.
1:35 Jury: [haha]
The jury: Man-left: David Prachař, actor (CZ); Blonde: Dianka Mórová, actress (SK); Brunette: Marta Jandová, rock singer (CZ); Man-right: Jaro Slávik, music producer (SK)

TV Prima Cool, the quirky channel of the Czech commercial TV Prima – Cool airs The Big Bang Theory, Futurama, The Simpsons, TopGear, and tons of other "contemporary Anglo-Saxon" shows and often accompanies them with funny teenage-like slang and video transitions resembling computer games – has created a stellar edited parody out of Greta Thunberg's U.N. speech and some sequences from "Czechia Slovakia's Got Talent".

With 90% of positive votes, the viral video is #1 on YouTube in Czechia as of October 6th and 7th and will approach 1 million views after four days.

More seriously, some shticks are amazing. These two Ukrainian acrobatic kids in pajamas, Katya (8) and Nikita (11), were amazing. They also got a golden buzzer (a button to directly advance to the final round) from Marta Jandová – who was really terrified that the girl was going to kill herself. This Belgian pantomimist with a fake rodent, Elastic, was funny, indeed. Because of these two, a small Russian female dancer etc., some of us renamed the contest to "Everyone But Czechia and Slovakia Has Got Talent". ;-) The top singing is brought by the Armenian girls from Prague, if you care.

More videos from the TV show.

The Cretaceous vs the Gretaceous

A British left-wing rag, The Independent, has finally admitted that Greta Thunberg is a pathological liar.

They have published evidence (including her own confession) that Greta Thunberg had a dream – and one about the powerful. But in the U.N. speech just days away from that article, she claimed that the powerful have stolen her dreams. Clearly, according to The Independent, the powerful gave her the dreams because they appear in those dreams – instead of stealing them.

People shouldn't be lying in front of the microphone in the United Nations in this self-evident and provable way. I eagerly await the admission by The Independent that everything else that she is saying are lies, too.

Gravitinos+axions as a cure to the Hubble tension

There are many interesting HEP papers on today. I will pick two representatives. First, the Duchman Rik van Breukelen of CERN/Geneva proposes to refine the Raju-Papadodimas notion that the "black hole interior field operators are state-dependent", a thesis that has been discussed on this website repeatedly:

Black Hole State Dependence as a Single Parameter
He does accept that the operators have to be state-dependent (well, he's been a co-author of Papadodimas) but tries to minimize the state-dependence – by saying that the dependence is just through one number, a time shift. He says that while it's hard to construct the black hole interior field operators and people used to say that it was impossible (within AdS/CFT), constructions exist that depend on the pure state. But the underlying problem is that the time runs backwards inside – and therefore one may fix the problem by quantifying how much time has elapsed (in the opposite directions) since the moment when the inside-clock and outside-clock matched.

Karel Gott: 1939-2019

Karel Gott, a tenor with a flawless diction and a wide range including a resounding falsetto, widely regarded as the most legendary singer of Czechoslovakia and Czechia (and an amateur painter and a soccer goalie, among other things), died of aggressive acute leukemia yesterday before the midnight, at age of 80 – at home and in quiet sleep, after he decided to simply stop the exhausting treatment of the incurable illness and die a bit naturally and happily.

Gott was conceived days after the Munich Treaty in Fall 1938 – I don't know how many days – and was born in my hometown of Pilsen, the Protectorate of Bohemia and Moravia, on July 14th, 1939 – exactly 150 years after the Bastille (a French prison) has fallen. You may listen his remake of Aznavour's song, When I Was a Boy, [in the heavenly Nazi-occupied Pilsen,] songs had a sweeter sound, trees were taller, rivers were cleaner, the climate was warmer than today, the promises were safer, and you have stolen my childhood and dreams.

His family moved to Prague when he was 6. He was trained as an electrician and started to do music in 1958. In 1960, his father cried that he failed to conceive a skillful son; don't imagine that there was any harmony between these two men. The dad was shocked that the son wanted to sing – and to make things worse, to the microphone. ;-)

Even in the liberal 1960s, his type of music was considered extremely brave, revolutionary – you know, like rock'n'roll where he sort of belonged for years and more than Elvis Presley. His somewhat high pitch voice helped that controversial image – just like his highly idiosyncratic "dancing" that accompanied his singing. (He had to have a choreographer e.g. for The Safebox, right?) This controversial character of the "heavenly Charlie" sounds like news from a different geological epoch – for many decades, Gott has been the ultimate template of the mainstream musician who can't possibly insult anybody.

Worries about extinction in 10-15 years reveal deep scientific illiteracy of the young, urban masses

The climate hysteria was revived one year ago (when Greta Thunberg was chosen by Soros-funded groups to become a truly religious mascot of this insane movement) – and it has reached unprecedented levels. Not only scientifically illiterate but literally illiterate kids have "read" somewhere in the IPCC reports that the world will end in 12 years (although the IPCC is dominated by crazy crooks, it's not there). How many people believe in these doomsday scenarios?

A week ago, Scott Rasmussen published results of a poll. The percentage of the Americans willing to believe claims about the possible imminent extinction of the human race is between 1/2 and 1/3. The most shocking numbers say that 51% of the younger voters under 35 believe it is "somewhat likely for humanity to be wiped out [by anything] in a decade". Similarly, 45% of urban residents think "humanity may be wiped out by climate change in 10-15 years".

The stupidity of the underlying assertions is breathtaking and the percentage of the people willing to endorse them is terrifying. And the opposition to the cattle and fossil fuels – our most important source of energy – could be just the beginning. Once the staggering stupidity of the masses becomes normal, you may promote even crazier and more devastating superstitions. There seem to be no limits to the stupidity right now.
