Deep thinkers build conjectures upon conjectures upon 5+ more floors

Among the world's string theorists, Sheldon Cooper has given the most accurate evaluation (as far as I can say) of the critics of string theory:

While I have no respect for Leslie [Winkle, a subpar scientist designed to resemble a hybrid of Sabine Hossenfelder and Lee Smolin] as a scientist or a human being for that matter we have to concede her undeniable expertise in the interrelated fields of promiscuity and general sluttiness.
Not even Edward Witten has ever put it this crisply. Winkle has rightfully thanked Sheldon for that praise. Well, I also don't have any respect for the string theory haters as scientists or human beings, for that matter. But I am regularly reminded that the disagreement is much deeper than different opinions about some technical questions. It's a disagreement about the basic ethical and value system.

Search for ETs is more speculative than modern theoretical physics

Edwin has pointed out a new tirade against theoretical physics,

Theoretical Physics Is Pointless without Experimental Tests,
that Abraham Loeb published at pages of Scientific American which used to be an OK journal some 20 years ago. The title itself seems plagiarized from Deutsche or Aryan Physics – which may be considered ironic for Loeb who was born in Israel. And in fact, like his German role models, Loeb indeed tries to mock Einstein as well – and blame his mistakes on the usage of thought experiments:
Einstein made great discoveries based on pure thought, but he also made mistakes. Only experiment and observation could determine which was which.

Albert Einstein is admired for pioneering the use of thought experiments as a tool for unraveling the truth about the physical reality. But we should keep in mind that he was wrong about the fundamental nature of quantum mechanics as well as the existence of gravitational waves and black holes...
Loeb has a small, unimportant plus for acknowledging that Einstein was wrong on quantum mechanics. However, as an argument against theoretical physics based on thought experiments and on the emphasis on the patient and careful mental work in general, the sentences above are at most demagogic.

The fact that Einstein was wrong about quantum mechanics, gravitational waves, or black holes don't imply anything wrong about the usage of thought experiments and other parts of modern physics. There's just no way to credibly show such an implication. Other theorists have used better thought experiments, have thought about them more carefully, and some of them have correctly figured out that quantum mechanics had to be right and gravitational waves and black holes had to exist.

The true fathers of quantum mechanics, especially Werner Heisenberg, were really using Einstein's new approach based on thought experiments, principles, and just like Einstein, they carefully tried to remove the assumptions about physics that couldn't have been operationally established (such as the absolute simultaneity killed by special relativity; and the objective existence of values of observables before an observation, killed by quantum mechanics).

Note that gravitational waves as well as black holes were detected many decades after their theoretical discovery. The theoretical discoveries almost directly followed from Einstein's equations. So Einstein's mistakes meant that he didn't trust (his) theory enough. It surely doesn't mean and cannot mean that Einstein trusted theories and theoretical methods too much. Because Loeb has made this wrong conclusion, it's quite some strong evidence in favor of a defect in Loeb's central processing unit.

Parker Solar Probe will touch the Sun

But won't it break?

Can you encounter redheads in Czechia? You bet. Over percent – and around two percent at some places.

Czech-German singer Debbi (Deborah Kahl) wanted to Touch the Sun – while others wanted to use the song to touch Metaxa, a fancy Greek alcoholic beverage. She was standing on shoulders of giants but it wasn't full-blown plagiarism because Erin McKeown is a redhead, too. McKeown named her song Slung-Lo but she clearly meant the gravitational slingshot.

Quintessence is a form of dark energy

Tristan asked me what I thought about Natalie Wolchover's new Quanta Magazine article,

Dark Energy May Be Incompatible With String Theory,
exactly when I wanted to write something. Well, first, I must say that I already wrote a text about this dispute, Vafa, quintessence vs Gross, Silverstein, in late June 2018. You may want to reread the text because the comments below may be considered "just an appendix" to that older text. Since that time, I exchanged some friendly e-mails with Cumrun Vafa. I am obviously more skeptical towards their ideas than they are but I think that I have encountered some excessive certainty of some of their main critics.

Wolchover's article sketches some basic points about this rather important disagreement about cosmology among string theorists. But there are some very unfortunate details. The first unfortunate detail appears in the title. Wolchover actually says that "dark energy might be incompatible with string theory". That's the statement she seems to attribute to Cumrun Vafa and co-authors.

Most references to long-term thinking are just Marxist delusions

These days, we've heard the phrase "long-term thinking" from Elon Musk and his fans. But I am running – and many of you must be running – to various arguments where the opponents refer to the "long-term thinking" and "long-term visions" very often.

Just to be sure: I am not saying that there is a universal law or a logical argument that would imply that "long-term thinking" must always be an excuse for Marxist delusions. I am not even saying that I am avoiding references to "long-term thinking", "long-term perspective", "long-term visions", and so on. Each of us, including your humble correspondent, often has to distinguish the perspectives associated with short and long timescales.

But yes, I am saying that in more than 90% of the real-world situations in which "long-term thinking" is used as an argument or a slogan meant to settle a controversial issue, the users of that phrase are Marxists or very analogously deluded leftists who just don't have a clue how the world works (or who pretend not to have a clue) or people who suffer from a totalitarian megalomania or more ordinary people who simply want to justify their laziness.

Market manipulation: psychopath Musk remains at large

Forget about the heroic diver's being a "pedo". Forget about the requests sent to the suppliers to return the money they have received for their parts. Forget even about the totally disgusting, Smolinesque blackmailing by Musk who demanded a critic named Montana Skeptic to be fired by his employer (a Tesla fan) if he's not silenced. Montana Skeptic was actually silenced. It's just absolutely terrifying.

Now, Musk has gone to an entirely new level. He hates the people people who short his company because they dare to point out that Tesla is insanely overvalued – and they are willing to support this proposition with their money. And they don't call Musk a Messiah which is what he's used to from his low-IQ fans.

On top of that, he needs the stock price to be above $359 or so, otherwise the maturity of some special $900 million convertible bond will be much more costly in Fall 2018. So why wouldn't he manipulate the price by claiming that the right price should be $420?

Now, 420 is slang for "marijuana". On April 20th (4/20), leftists celebrate the Marijuana Day and they get high – and therefore ready for April 22nd, Lenin's Earth Day. It is also the country code to call my Czech homeland – where people may hold 15 grams and 5 plants of marijuana legally (so the same number 420 doesn't have to be a coincidence). He may always say that he was just joking. But it was totally obvious that the market – filled with "investors" who are low-IQ fans of Musk – would react. And it did. The price jumped by some 10% towards $380 or so, matching the previous all time high.

(By the way, the cryptocurrency prices dropped some 10% in recent 24 hours. These two price changes could be related. The same "investors" could have sold the Bitcoin and buy Tesla yesterday.)

What's the right way to stop the Big Tech censorship?

Breaking up companies? Quotas on Republicans? Reclassification of them as utilities? Raids on headquarters? New taxes/fines for their harm against right-wingers? Removal of the U.S. citizenship for CEOs?

I am no listener of Alex Jones – maybe he sounds too tough or too non-intellectual to me (and, despite the vague ideological agreement with general political things, I would probably label many of his musings "dumb conspiracy theories") – but today's ban of his and Infowars pages, channels, profiles, and Podcasts by Apple, Facebook, Spotify, and (now also) YouTube (look at the creepy error message shown to 2+ million followers!) all did the same thing within 12 hours – a clear collusion by a cartel) is a clear sign that the freedom of speech (especially for right-wingers) is dying in the U.S.

(Hours later, Jones was also removed from LinkedIn and Pinterest.)

Ironically enough, this dying – escalated by this ban that Matt Drudge predicted years ago – has accelerated under the Republican president Trump. Infowars were basically given no specific explanation of the reasons. Terms of Service violated. Hate speech. Whatever. Four biggest Internet companies suddenly made the conclusion at the same moment.

You may watch Alex Jones' reactions live now. I've watched it for 20 minutes now – it's spectacular, it looks like he was preparing for this day for 25 years.
Lots of related information may be found on the Twitter account of a VIP employee of Infowars, Paul Joseph Watson, whom I like, admire, sometimes follow, and I surely endorse all his comments about these events.

Some people defend similar policies by saying that the companies are private and they can ban anyone they want. There's some true core in this statement. But every sane and sensitive person must feel that it doesn't sound right. Why it doesn't sound right? These Big Tech companies are clearly introducing political censorship to the whole U.S. political landscape. Why is it exactly wrong what they're doing?

Food scanner scams: non-physicists overestimate the "diversity of food"

They also underestimate the importance of expertise, experience

Hours ago, Thunderf00t posted a wonderful new 50-minute-long video:

ThunderF00t chooses "Pražská vodka", i.e. the "Vodka of Prague", as his template for an ethanol-water mixture. He deserves special compliments for that. That Czech vodka is based on the 1978 diploma thesis of Ing. Eugen Skalický at Prague's University of Chemical Technology and uses the Highland (Vysočina) Wheat to produce the ethanol. It's been Czechia's bestselling vodka, is still near the top, but I have no idea how he got one unless he is just visiting my homeland.

It shows how utterly useless two smartphone-based, StarTrek-based food scanners or spectroscopes are – and why their crowdfunding campaigns that had collected $3 million and $0.4 million must be considered scams.

These two bogus revolutionary products, TellSpec and Scio, cost $149 or $250 (plus $1,000 for software etc.), respectively. You point them to a food, some photons are reflected, the spectrum is evaluated, and you know what's inside the foor or pills perfectly, the nutrition values, and everything else.

SJWs turn a white gay's life to hell for his thoughtful anti-racist essay

After some time, I was shocked by the atmosphere around the U.S. media landscape and the selective and brutal suppression of the freedom of speech.

Well, it's not just in the U.S. Let me start with another example. Canadian right-wing pundits Lauren Southern and Stefan Molyneux went all the way to New Zealand to give a speech about the free speech. The owner of the place described himself as a great free speech advocate. The venue was revealed hours before the talk, for security reasons, and immediately afterwards, the organizer said that free speech was lethally dangerous and he wouldn't allow any Canadians in his place. He or she was clearly threatened – economically or by explosives. You can no longer give speeches about the free speech in New Zealand. The extreme left-wing terrorist movement is sufficiently organized to kill almost all such events in practice. The degree to which these societies are already fudged up looks stunning to me.

The Powerstation in NZ which suddenly decided it hated free speech.

But let's return to the U.S. The New York Times hired an Asian American writer Sarah Jeong as a tech-related member of the editorial board. I have seen no evidence that she has the skills of a professional writer but she has associated herself with the feminists in the Gamergate controversy and The New York Times probably wanted to please millions of left-wing activists by hiring an incompetent inkspiller who is otherwise on the "right" (meaning far left) side.

Adversarial collaborations don't solve anything

Tetragraviton has presented himself as an idealist diplomat and he proposed

Adversarial Collaborations for Physics.
Arguments may sometimes be harsh, and that's true in physics, too. The two sides accuse each other of moving the goalposts, double standards, misinterpreting things, ignoring the evidence, and so on. Tetragraviton has a magic solution – to force both sides to co-author a paper. These enemies fudge together and have a baby, a paper. Then they become friends who share the facts and standards. And the truth magically sprinkles from that heterotic paper and they love each other forever. Amen.

Adversarial collaborations were originally proposed as a solution to solve the arguments between the believers in the extrasensory perception on one side and the sane people on the other side. If you write a paper along with a guy who was abducted by the extraterrestrial aliens and talks to them through telepathy, that will surely lead to your mutual cultural enrichment and the joint work will clarify everything! ;-)

Expect no apologies here: I am mocking the concept of such joint papers because a joint paper assumes – and implies – that the co-authors believe to be peers in some intellectual sense. And a competent scientist simply can't consider a nutcase believing in supernatural phenomena as his intellectual peer. Also, as the Wikipedia article explains, adversarial papers are most possible when they're not needed (when the two sides actually agree about some basic axioms and methodology) and least possible when they're needed (when the differences in the methodology, axioms, and priorities are deep).

Lumo spiral visualization of sound for the deaf

...and for all other true lovers of music and sounds...

In a previous text, I proposed a visualization of the sounds that would allow the deaf people to hear – including the distinguishing of vowels, accents, different people's voices, consonants, other noises, music, frequencies, octaves, melodies, different musical instruments, chords and several people talking or singing simultaneously, and everything else.

The idea is that the brain connected to the eye just gets trained to evaluate very similar information as the information that is coming from the ear. Ideally, the eye (plus a piece of the brain connected to it) should work "almost the same" as the ear.

Someone has mentioned the WinAmp visualizations (or Milk Drop), click for an example. Yes, that's what I roughly mean except that this video example and most others don't allow me to "hear" anything. They seem like pretty pictures that are just slightly affected by the sound that is being played but there's no straightforward way to extract the precise sound from the picture.

Edward Witten, dinner table group think, and \(P=NP\)

Scott Aaronson has posted at least two new comments here in which he demands to be considered a "possible co-author" of a paper by Ewin Tang that has found a recommendation algorithm that Aaronson insisted to be impossible.

I think that given Aaronson's frantic efforts to discourage this kind of research, it would be insane if he were a co-author of Tang's paper. Aaronson is testing the waters – could he get away with stealing one-half of the credit, after all? I sincerely hope that Tang already has enough freedom not to allow such a shocking development.

But Aaronson discussed our main dispute, whether complexity theorists should be open about the truth value of \(P=NP\). Aaronson claims that they shouldn't be open-minded. Even without a proof, the non-existence of polynomial algorithms for \(NP\) problems should be considered an "established wisdom", the phrase that Aaronson still uses for the now demonstrably untrue, unsubstantiated, irrational belief that Tang's algorithm cannot exist.

Aaronson's teenage student amazingly proves that Aaronson's strong beliefs are only "backed" by arrogance, bigotry

Ewin Tang proved the opposite task than Scott Aaronson assigned him as if it were a fact

I think that Scott Aaronson is an intelligent man but over the years, I have pointed out that he's staggeringly irrational – and therefore not very intelligent – in a wide variety of issues. Those include most of the political questions which is unsurprising but Aaronson also holds strong beliefs that directly touch his expertise but they're utterly irrational, too.

Undergraduate student Ewin Tang

One of his beliefs is – it's almost as general as what I am going to say – that whenever some fast (polynomial) algorithms haven't been found so far, they will never be found. The most explicit "substatement" of this type is Aaronson's statement that \(P\neq NP\) must be treated basically as a fact even though neither \(P\neq NP\) nor \(P=NP\) has been proven.

In numerous blog posts, I pointed out that every pair of "qualitative propositions" in pure (especially) discrete mathematics that haven't been proven to be strictly equivalent must be considered uncorrelated. In other words, no partial, "rather good", evidence may ever exist. It means that when you formulate a proposition about discrete portions of mathematics, fair and rational mathematicians simply must remain open-minded and allow the research into "possible better evidence that \(P=NP\) as well as possible better evidence that \(P\neq NP\)".

A sound visualization app that makes deafness irrelevant

There are some very good programmers among the readers – this could be a fun exercise. I just accidentally "chatted" with a deaf guy on Twitter and decided to spend a few more minutes by thinking about some high-brow, hi-tech technological ways to aid the deaf people – who may represent, according to some counting, up to 5% of the world population.

It's a huge market. It could be interesting to create a helpful app that effectively "returns the hearing" by maximally visualizing the information contained in the sound. That app could be used with some phones but maybe with some "Google Glasses" or a similar gadget that the deaf folks could find more helpful than others.

An 11-dimensional brain: a bit too exciting jargon

A month ago, lots of media wrote about a truly exciting topic, the eleven-dimensional brain. Some links to the article may be found in

The “Eleven Dimensional” Brain? Topology of Neural Networks
by Neuroskeptic, a blogger at the Discover Magazine. I recommend you that article if you want to demystify the whole thing. It's likely that most of the "regular media" prefer to keep you mystified.

This "higher-dimensional brain" reminds me of some papers that caught my attention in the mid 1990s – papers by (otherwise) string theorist Dimitri Nanopoulos and his collaborators such as Mavromatos. To give you a great example, look at this 1995 hep-ph (!) paper
Theory of Brain Function, Quantum Mechanics and Superstrings
Micropoulos wrote a lot about the NanoTubules – OK, it was the other way around, Nanopoulos wrote about MicroTubules. I was always rather skeptical and that skepticism was sufficient to prevent me from trying to read such papers carefully.

Tomáš Haas, Czech Steve Bannon (1947-2018)

On Friday, Mr Tomáš Haas died at 15:30. Lots of his Facebook friends including your humble correspondent were sad. He was a major Czech right-wing thinker and a former aide to President Klaus and two Czech prime ministers – he was perhaps one of the crucial guys who do lots of the mental work behind the scenes but remain largely unknown to everybody. His health problems have lasted for some year or years but I think that a month ago, I still saw him at Klaus' birthday party in Prague where my shortage of time (and excess of sweat, due to running uphill in Prague) was unfortunately extreme.

I was a bit worried that former president Václav Klaus wouldn't write about the sad event. But here it is:

Václav Klaus's eulogy of Tomáš Haas

Tomáš Haas was an extraordinary personality of the Czech Right. He was a complete exception among the Czech emigrants who were returning from the U.S. or Canada to their homeland after the 1989 fall of communism. All of them were tainted by the American "liberal" world. Haas was the only white crow among them.

He stood for freedom, democracy, and common sense. He was against the political correctness, multiculturalism, and the fawning over the migrants in the contemporary Europe. His texts and interviews were a great source of energy and refreshment for all of us.

He was a close friend of the Institute of Václav Klaus and I must reveal that he was a top candidate for the Annual Prize of IVK for 2018. For some time, we will reproach ourselves for having missed the opportunity in 2017. Now we can't fix it anymore but we will never forget about Tomáš Haas.
I've talked to him for an hour in 2007 – when both of us were most active in the fight against the climate hysteria. He was an incredibly kind man.

A Canadian journalist proves a Sydney suburb obeys the Sharia Law

I am getting and watching lots of similar videos and follow many stories – the recent invasion of the Africans to the Spanish enclaves bordering Morocco (they had feces, lime, flamethrowers) was pretty fascinating.

It makes no sense to discuss everything but at some moments, I think it's a good idea to see something and think about it.

Einstein's breakthrough was far deeper, more philosophical than assumed

Relativity is about general, qualitative principles, not about light or particular objects and gadgets

Some days ago, we had interesting discussions about the special theory of relativity, its main message, the way of thinking, the essence of Einstein's genius and his paradigm shift, and the good and bad ways how relativity is presented to the kids and others.

Newton has introduced mathematics to the thinking about the physical phenomena including the accelerated motion of objects. This mathematics was compatible with the common sense and it allowed the people to think as reductionists. I think that most people who can pronounce "relativity" understand this viewpoint.

The world is composed of various objects – particles, solid objects, fields – and they obey some differential equations with time as the independent variable. These equations may be written down, solved, and exploited. The intuition is that the world is composed of many things, each works in some way, and we are learning how they work one by one.

North Macedonia is a great name

Greeks trying to rob Macedonians of their name are brain-dead fascist filth

For many years, Greece was preventing Macedonia, a post-Yugoslav country, from joining NATO and the EU where – as far as I am concerned – Macedonia belongs much more than Greece does. Why did they do it? They didn't like the name.

Days ago, prime ministers of Greece and Macedonia Tsipras and Zaev agreed to solve the dispute by renaming Macedonia to "North Macedonia" – or "Northern Macedonia"? It's a great solution which recognizes that the current republic of Macedonia doesn't cover the whole territory that has been associated with that name. On top of that, this "new name with an adjective" is of a geographic character which means that it doesn't provoke anyone with ethnic suggestions.

The Balkan peninsula is full of hate and fanaticism about trivialities that Central European people such as myself find totally baffling. So even this solution faces a significant backlash in both countries. A nationalist Macedonian party finds the addition of "North" to be too big a sacrifice. And lots of Greeks claim that the Macedonians shouldn't have the right to use the root "Macedon" anywhere at all.

I find the latter group to be especially, stunningly nasty. Something is really wrong with a nation in which a Bolshevik moron such as Alexis Tsipras ends up being of the more reasonable guys in questions that the life actually brings every day. It's pretty crazy that we belong to the same EU with these Greeks – a union that many people would love to turn into a superstate.

Laymen's thirst for overly simple solutions and \(0^0\)

Most people seem to be irrational, in fact obsessively irrational, and that's manifested even in mundane discussions. OK, ask how much is the zeroth power of zero:\[

0^0 = ?

\] Great. In calculus where the arguments are continuous, there is still a general way to calculate a power:\[

a^b = \exp(b \log a).

\] The logarithm is natural. Apply it to \(0^0\) and you get:\[

0^0 = \exp(0\log 0) = \exp(0\times (-\infty)) = \exp({\rm ind}) = {\rm ind}.

\] Like \(0/0\), it's a classic indeterminate form. Well, yes, this \(0\times (-\infty)\) in the exponent is "more likely" to be "morally" zero (because the minus infinity may be modest "minus nine" times the logarithm of ten when the base is one billionth, close enough to zero; and the exponent is therefore one) but in principle, the product of the zero and minus infinity may be anything.

"Standard Model has no octonions in it" is politically incorrect, too

Left-wing activists stifle the discussion about anything so much that the Inquisition looks like a fresh air in comparison

My essay about Cohl Furey and octonions has been read by some 6,000 people, higher than the average, but the relative increase of insufferable trolls – and bans per article – was much higher than the increase of the number of readers.

Many people often present the medieval Inquisition as a textbook example of an institution that was preventing the people from researching and even talking about scientific matters. Many Christian readers love to defend or lionize the Inquisition or the Catholic Church and its officially sponsored thinkers – and they occasionally attack the likes of Galileo Galilei.

Make no mistake about it, I am squarely on Galileo's side and I would be on the analogous side even in disputes where science was represented by a less shining man than the founder of science.

However, I find it increasingly obvious that the Inquisition represented the freedom of thought and the open-minded approach to arguments relatively to the left-wing activists that have literally contaminated the whole Planet Earth by 2018.

Musk to suppliers: return cash, make Tesla profitable

It's their duty to bail out Musk, keep him a billionaire
TSLA is dropping some 6% at the beginning of today's session

The Wall Street Journal broke a story – covered by everybody – that sounds as a joke but I think it's true. Elon Musk's company has asked a supplier – and most likely, very many if not all suppliers – to return some money (50-100 percent) that have already been paid by Tesla for the parts that Tesla bought since 2016 "in order to turn Tesla profitable".

It's incredible. After some $10 billion has been sucked from the pockets of the U.S. taxpayers, additional tens of billions were sucked from the pockets of the brainwashed Tesla fans among car buyers, investors, and lenders, the company still can't afford to pay the normal price of the parts – even parts that have already been delivered and paid. Crony capitalist Elon Musk has become so incredibly arrogant and "entitled" that he believes that his business partners are obliged to place his being a billionaire, or Tesla's profitability, above their own profitability or financial survival.

They would be complete loons to return any of the cash. But it's plausible that some of the supplier companies are managed by Tesla fans who actually are loons, so anything is possible.

Europe should enthusiastically accept Mnuchin's free trade offer

A trade war won't ever make America great again. If the U.S. reduces its trade deficit without damaging its good image as the greatest destination for investments and the home of the most important reserve currency, it will simply strengthen the U.S. dollar and the stronger U.S. dollar will lead to the growth of the trade deficit to levels comparable to the present one.

If the U.S. or Donald Trump manages to reduce the attractiveness of the U.S. dollar, treasuries (U.S. bonds), and stocks, then the U.S. trade deficit may indeed shrink or disappear but many Americans will notice that the lower purchase parity resulting from the relatively weaker dollar – one that isn't stronger than expected – isn't something that they really wanted.

Ask people e.g. in the black Africa: Would they love to earn a strong currency and be rich by printing pictures of Benjamin Franklin or his African counterpart if there were one – instead of the hard work they have to do today? They would definitely love it! It's largely irrational for Trump to dream about the balanced trade or a weaker dollar. The apparent Trump's weak dollar policy (which is so different from the strong dollar policy verbally supported by most Trump's predecessors) is a result of his one-sided mercantilism. America would surely realize rather quickly that it doesn't contain just workers who want to be employed – it also (or primarily!) harbors over 300 million consumers who want to buy products cheaply! ;-)

Cohl Furey understands neither field theory nor octonions

Her mathematical masturbations are physically meaningless

Quanta Magazine's Natalie Wolchover wrote a cheesy celebration

The Peculiar Math That Could Underlie the Laws of Nature
of a would-be theory of everything by Ms Cohl Furey that is claimed to be based on the octonions \({\mathbb O}\). If you read it, the human part of the story as well as the spirit of the mathematics used for physics sounds virtually isomorphic to Garrett Lisi and his would-be theories of everything based on the exceptional group \(E_8\). So people are told about some ingenious outsider who has some very non-intellectual hobbies but who can still get closer to a theory of everything than all the professional physicists combined by insisting that an exceptional mathematical structure underlies the patterns of particles and fields in Nature.

The main difference is that Lisi is just a "surfer dude" while Furey is a "ski-accordion-yoga-mat-rented-car gal trained in martial arts, as her muscular physique betrays". Cool: the surfer dude is clearly a second-rate genius when compared to Furey now. ;-)

But both of these people misunderstand the meaning of the mathematical structures they claim to love – and they are trying to use them in field theory in ways that destroy the relationships that make the beloved mathematical structure what it should be; or that are impossible in quantum field theory.

Postulates of quantum mechanics almost directly follow from experiments

Most of the ordinary people who have tried to understand modern physics find the novel logical framework of quantum mechanics challenging. Some of them have become full-blown anti-quantum zealots which means that they scream "it cannot be true", "physics must ultimately be governed by the logic of classical physics" – well, they love to use different words but this is exactly what they mean.

Although many of these people may have achieved various things, I find it impossible to consider these people intelligent. I have explained the consistency of quantum mechanics (internal consistency and compatibility with observations) and the failure of any "realist" proposal to replace quantum mechanics from many perspectives.

Here, I want to argue that it's pretty much obvious that certain experimental facts just cannot possibly have a different explanation than the precise framework of quantum mechanics.

Out of Tesla's stock price, $300 is due to Musk's silly PC clichés & government's distortion of markets

I think that most people who seriously trade stocks (or invest into stocks) will agree that they are usually trying to estimate the fair or sustainable price of their stocks with the precision that is finer than 10%. Serious investors estimate the earnings with a similar accuracy and think hard whether P/E (the price-to-earning ratio) should be 10 or 20 and what could affect it. At the end, the stock price should be equal to the mean value of discounted life-long profits that the company will generate. So investing isn't quite a high-precision physical science but it is clearly about numbers that are supposed to reflect some underlying reality rather accurately.

Meanwhile, there are things one can buy where the precision isn't as good as 10%. In fact, the current price routinely differs from any fundamental value by orders of magnitude – sometimes infinitely many orders of magnitude (like in the case of the Bitcoin and other unbacked, worthless cryptocurrencies).

Tesla Motors stocks are somewhere in between regular stocks of car companies and the Bitcoin. In the sense of the linear scale, Tesla is almost certainly closer to the Bitcoin because most of its price has nothing to do with realistic expectations about the business. More than 50% of the stock price is unexplainable by the usual rational computations and estimates. Most of the price reflects a religion of a sort, an assumption that the logic and numbers will change dramatically in the future and in the new scheme of the world, Tesla (like the Bitcoin) will play a role similar to God.

The U.N. migration compact is toxic

A few days ago, the representatives of 190 U.N. member states agreed with the


(full PDF text of the draft; press release).
The document is intended to legitimize mass migration and encourage all countries of the world to adopt the same rules how to deal with the migrants and refugees. This document has been planned since September 2016 when Obama, in the final months of his tenure, made sure that the U.S. was a part of it.

At this moment, it's a draft and the final version of the rules is supposed to be codified in Morocco before the end of the year.

As the media report, the draft was adopted "by consensus". That probably means that a herd of brainless sheep, one sheep representing one nation, was pushed to some meadows near Manhattan.

New Czech government depends on the communist party

Among humans, the former communist secret agent and current Slovak-born billionaire Andrej Babiš is unquestionably the single greatest threat for the Czech democracy after 1989. He has a disproportionate influence on politics, economy, and the media (he owns two of the most widespread dailies and Czechia's #1 commercial radio station, among others).

He has no respect for the parliamentary procedures, power sharing, and his constant whining combined with oversimplified, emotional and irrational, nasty accusations against all of his political opponents constantly reminds us why he is exactly the kind of an assertive yet primitive loyal bumpkin that the Communist Party of Czechoslovakia loved to hire up to 1989 and that were moved to labor camps in Germany of the 1930s.

But when he earned 30% votes in the October 2017 elections – which was enough to make the remaining 8 parties in the Parliament look like dwarfs – I wasn't hysterical. His coalition potential was very low, I expected him not to earn the confidence easily. I thought that the era of Babiš's first government without confidence would be rather nice politically – because a weak government is often a good government. I hope that you agree that this blog hasn't become a mirror image of Daily Kos with tons of anti-Babiš rants every day – which 98% of the current readers would be totally uninterested in, anyway.

And I think that I was right. It was nice when Babiš had to struggle for his own survival, when he had to šit into his pants every day and ask: Will I be arrested tonight or tomorrow? I am not an anarchist but when a modern government is limited by the fact that people may point out that it hasn't really earned a legitimate support from the Parliament, it's an advantage.

A quasi-smooth compact manifold may be hiding in monster group, pure gravity

The most extreme, simplest, consistent vacuum of quantum gravity could be Witten's monstrous \(AdS_3\)/CFT pair. The boundary CFT is a two-dimensional theory with the monster group symmetry which has been used to demystify the monstrous moonshine. The bulk seems to be just \(AdS_3\) with mo massless fields, just black hole microstates, which is related to the absence of the minimal nonzero-length roots in the (even self-dual 24-dimensional) Leech lattice.

By pointing out the absence of some twist fields using group theory arguments, Gaiotto has shown that counterparts of this theory don't exist for every \(N\) – a problem arises already at \(N=2\). But even if there only exists the \(N=1\) theory with the minimal \(AdS_3\) curvature radius, it's still interesting. Perhaps exceptionally interesting. It may be the most "negatively curved" \(AdS\) background in all of quantum gravity, among other things.

The holographic analyses often focus on the \(AdS_3\) part of the bulk geometry. So the assumption is that only the \(AdS_3\) geometry is "real" in the bulk. But I think that this is a superficial and uninspired treatment – and a similar oversimplification as if you said that the dual geometry to the \(\NNN=4\) gauge theory is the \(AdS_5\). Well, there's also the \(S^5\) in \(AdS_5\times S^5\). In fact, both factors have exactly the same curvature radius so if you don't neglect one, you shouldn't neglect the other, either.

Prosecuted prime minister appoints himself the minister of justice, too

Update: Thank God, due to the pressure, Babiš changed the plans and will nominate a different man, Mr Kněžínek, instead.
Suddenly, the EU doesn't care at all that the rule of law is collapsing in Czechia

For two weeks, Czechia has had an incredibly incompetent minister of justice. Mrs Taťána Malá was originally a substitute who could meet Mr Babiš in Lelekovice, a village of 1900 people.

But she managed to flatter Mr Babiš more than everyone else so she was invited to the Stork Nest, Babiš's luxurious farm co-funded by subsidies from his subsidy fraud, and she became a visible lawmaker for Babiš's party. Two weeks ago, he picked this average girl from a small village as the minister of justice. Meanwhile, it turned out that she has plagiarized both of her diploma theses.

Her yesterday's defense of the plagiariasm was truly painful, especially if you realize that the woman was supposed to enjoy the respect from Czechia's judges and other lawyers. We learned that things are OK because the whole pages aren't identical to the pages in the thesis she copied. Moreover, plagiarism was OK in 2005, we were told. (Obviously, the trend is going in the opposite direction. A similar kind of misconduct is being increasingly tolerated.) Also, the theory about rabbits is a bunch of facts so it's obvious that two women write identical 10-line paragraphs about this theory, we were told! Wow.

On top of that, her work was incredibly original, trumping Einstein's special theory of relativity. To get her degree, she measured the weight gain of male and female rabbits in winter – before they're fed and afterwards – and she decided that female rabbits don't gain much weight in winters. I have serious doubts about this "law" but even if it were right, I would probably disagree with the idea that college degrees should be given for weighing rabbits after the winter feeding season.

Spin correlations at ATLAS: tops deviate by 3.2 or 3.7 sigma

After some time, we saw an LHC preprint with an intriguing deviation from the Standard Model predictions. It appeared in the preprint

Czech justice minister: plagiarism, sycophancy, lies, obstruction of justice

The story of Mrs Taťána Malá [the first name is popular in Russia, the surname means "Small"] is infuriating but what's "refreshing" is that this scandal has nothing to do with the PC globalists' war on the civilization.

Former Slovak communist agent and billionaire Andrej Babiš won 30% in the elections in October 2017. It turned out to be extremely hard for him to earn a majority in the Parliament and his government hasn't earned confidence yet – after almost 9 months. In the freshly announced second government, one with social democrats that should be silently "tolerated" by the communist party and depend on it (for the first time since 1989), the justice minister is supposed to be Mrs Taťána Malá, a 36-year-old blonde.

John Huss' monster trial resembled MeToo witch hunts

On July 4th, the Americans celebrated the Independence Day – although a powerful algorithm at Facebook has pointed out that the Declaration of Independence is hate speech.

That holiday is followed by two Czech holidays. On July 5th, but 1155 years ago, Greek missionaries Cyril and Methodius brought writing (their artificial Glagolitic script) plus the Orthodox Christianity to Czechoslovakia (which was called Great Moravia).

The Czechoslovak and Czech presidential flag says "Truth Prevails" ("Veritas Vincit" in Latin, "Pravda vítězí" in Czech). The truth was favored by the first president Prof Thomas Garrigue Masaryk – but he probably celebrated the tradition of John Huss who is often associated with the struggle for the truth.

On July 6th, 1415, the Bohemian Church reformer and forefather of Protestantism Mr John Huss was burned at stake in Constance, as a heretic, during an intimidating council. Huss was (mostly) a fan of a critically thinking 14th century English scholastic theologian John Wycliffe (who wrote in Latin). This Czech Catholic priest gave lots of cool sermons, criticized [not yet carbon] indulgences and the corruption of the church officials, said that the church should be poor, all people should be equal in front of God regardless of their sex, nationality, wealth, they should look for the truth directly in the Bible and not ask priests, he always filled the Chapel of Bethlehem in Prague (by viewers including rabble, prostitutes, and Queen Sophia, among others), earned the hearts of most Czechs including the Czech aristocracy, and was inconvenient for the Catholic Church and the allied German political institutions – let us call them the CDU – which decided to murder him.

Huss was also the most likely originator of the Czech diacritical signs – the letters that we write as áéíóúůý žščřďťň these days (he started with dots above the letters, something that still exists in Polish).

Did 12 astronauts cause global warming by 2 °C on the Moon?

Or does an organized movement of brain-dead liars calling themselves "journalists" spread far-reaching cosmic superstitions about a mundane hot piece of dark surface under the sunlight?

How much a group of 12 men can change the world? Well, if they're apostles, they may have the last supper with Jesus Christ. They didn't have to pay a penny. Assuming that Jesus Christ was more than Warren Buffett, they saved over $39.6 million.

Incidentally, before He arrives again, they have accepted a temporary job. Every hour, they entertain tourists at the 600-year-old Prague Astronomical Clock (The Orloj). I've seen it many times but only now, I watched it carefully enough to notice that six of them only appear in the left window and six of them in the right window. In my life so far, I have never found it important enough to investigate this detail.

However, weeks ago, some media, e.g. How Stuff Works brought an eye-catching story. A group of 12 Unistatians – the astronauts – has caused the global warming... on the Moon! How did they do it?

Thank God, the European Parliament voted against the link tax etc. today

At the end of May, I wrote that the European Parliament was going to vote on banning the Internet.

Pretending that the policies were meant to defend the copyrights in a better way, the authors of the fascist proposal wanted to make it basically impossible for individuals to discuss the events in the world. If that proposal were passed, bloggers could be unable to quote sentences – and even link to the original source of the information – unless they paid a fee that only large corporations could afford.

The new rules were rather accurately described as a "link tax" and "upload filters". The consequences for the freedom of speech could have been existential.

Our Edwin Steiner is the current leader in the CERN-Kaggle TrackML challenge

Seven weeks ago, I invited the TRF readers to join the TrackML challenge organized by CERN and You are expected to write some code that tracks particles at the LHC. The reason why I invited the readers is that this category includes some smart folks – and I wanted to watch a familiar friendly name that quickly becomes the leader in a very big leaderboard.

Ladies and Gentlemen, the current leaderboard shows 490 participants or teams. And the top five of them are shown in the screenshot above (click the image to zoom in).

David Gross: make America great again

The first string theory's formula, the Veneziano amplitude, was introduced to physics in 1968, i.e. half a century ago.

In that year of 1968, Czechoslovakia tried its "socialism with a human face", and the experiment was terminated by the Warsaw Pact tanks in August (next month, we will "celebrate" that). Meanwhile, the youth in the West tried a seemingly similar revolution. Only in recent years, I was forced to realize that what started in the West was really going in the opposite direction than the 1968 Prague Spring.

At any rate, the annual conference, Strings 2018, didn't forget about the Veneziano far-reaching playing with the Euler Beta function. Veneziano was present. The 2-hour-long panel discussion at the end of the conference is arguably the most layman-friendly video produced by the conference. One frustrating fact is that the video only has 1500 views as of this moment. No journalists were interested in the conference.

Prague Stock Exchange: stocks in the index

Lots of TRF readers have spare millions of dollars. Maybe you can buy stocks from the whole world. You may be underexposed to Czechia – which enjoys the growth above 4%, has a 2% unemployment, and its stocks generally look undervalued. is one of the professional servers that cover the stock market. You may find the current prices (or prices delayed by 15 minutes) of the big Czech stocks, smaller Czech stocks (the "Free" market), Central and Eastern European stocks, Western European stocks, and the U.S.

The Prague index (PSE) oscillates around 1066 as of this moment. See the current composition.

Will Trump see the light before he kills Harley-Davidson, others?

Bob Sykes posted a comment against free trade. His view is rather widespread among the self-described U.S. conservatives although I still associate this view with the Bolsheviks. You know, Czechia had tons of companies that used to export to the Soviet Union during communism and they went bust after 1989 because they were not competitive. Western European buyers weren't satisfied with similar stuff as our Soviet comrades. I even bought some of these companies' stocks in the voucher privatization. ;-) (But I also bought some companies that are still around.)

But almost everyone agrees that it's right that a big part of these companies went bust. It's stupid to produce lousy products by obsolete or inefficient assembly lines. We wanted to get modernized, we did. The newer assembly lines swallowed the workers within a few years. These days, Czechia has the lowest unemployment in the world, near 2% by some methodologies. (The economy is overheated partly because of the excessively long 2013-2017 interventions keeping the Czech crown artificially weak.) The exports are higher than two-thirds of the (nominal) GDP. Imports are just a bit lower – we have a surplus. (But because of the outflow of the dividends, some 5% of the GDP, the current account is approximately balanced.)

You surely don't expect a nation like mine to support protectionist fairy-tales. Almost no one does so here, not even the communists. I understand that the situation may be different elsewhere – others may be more likely to view themselves as losers of free trade. But I think that in most such cases, something essential is wrong. Either the uncompetitive companies have been unnaturally supported by the government policies and became dinosaurs. Or they're just lying and they want unfair advantages. Or the country runs endemic deficits which is more possible if it uses the currency that doesn't adapt to the country's needs, like Greece, and so on.

In countries that have the control over their currency, that are non-whining etc., free trade must be the better option.

Permanent migrant quotas abandoned

I would actually vote "Stay" in a Czechout referendum if it took place now

The EU summit was primarily dedicated to the immigration to Europe – which was a significant trend that was somewhat bizarrely classified under the "asylum policies" of Europe (although those should only deal with a small number of individuals).

And I think that the most important outcome is that Angela Merkel and her comrades have surrendered and abandoned the plans to force migrants on individual European countries, using the mechanism of the permanent quotas, and to force the migrants to go to arbitrarily or randomly chosen European countries.

This is significant because the large European countries were considered to be the "owners of the EU". Germany and France were frantically supporting the insane concept of the permanent quotas. They had the backing of Spain, Benelux, and several other countries (Italy has belonged to that group just a month ago). This coalition looked impossible to beat. But it was beaten.

Some countries such as Poland and Hungary have always believed that their viewpoint may influence the direction that Europe takes. That's why most Poles and Hungarians actually want to stay in the European Union, despite the self-evident harassment of these nations by Brussels. They have believed that Europe may sometimes evolve according to their wisdom. And they were proven right. Maybe the European Union isn't such a hopelessly totalitarian construct where all the answers are predetermined in some actual centers of power.

James Wells' anti-naturalness quackery

Sabine Hossenfelder celebrates a preprint titled

Naturalness, Extra-Empirical Theory Assessments, and the Implications of Skepticism
and rightfully so because its author, James Wells, could literally shake her hand right away and join her personal movement of crackpots. Wells' paper isn't just wrong – it's incredibly stupid. Thankfully, he only sent it to the "History and Philosophy of Physics" subarchive although it was cross-listed to the professional subarchives. (Maybe the arXiv moderators should be thanked for correctly classifying this paper as social sciences, pseudosciences, and humanities.)

Hungarian FM unmasks the extreme unfairness, activism of BBC

It's very far from the first time when I was impressed by the Hungarian foreign affairs minister, Szijjártó Péter (I am showing my idea about the Hungarian language by being able to permute the names). But after this exchange at the BBC, I would be very happy if the Visegrád Group hired him as a shared minister of foreign affairs. As a guy who's been told by 20 different Americans that his accent was Hungarian, I have the right to propose that! ;-)

Seriously, I don't remember a minister of foreign affairs of Czechia who would be this competent.

First of all, I liked his English and rhetorical skills. Second of all, I liked his being full of energy yet fully keeping control over his emotions. Third of all, I liked the content.

Keating's religious pseudoscience, fine-tuning, and Thunderf00t

I guess that John Archer won't be happy about this blog post but he's a strong man who will survive, I believe.

In April, I discussed Brian Keating, a key guy behind BICEP and measurements of the polarization of the microwave background. He wrote a book bragging about his bitterness that Nature wasn't generous enough to guarantee a Nobel prize for himself. He would like to reform the Nobel prize in clearly harmful ways.

And Keating deceitfully presented the multiverse as a left-wing construct. His claims that he is a conservative may be nothing else than the promotion of various nutty religious views on modern physics.

But only today in the morning, I learned about his April 2018 monologue he recorded for Prager University – not to be confused with the Prague University, my Alma Mater – about God, fine-tuning, and the multiverse. He thinks that the fine-tuning is everywhere and only allows two beliefs, the multiverse and God, and the multiverse sucks, so God is real.

It's legal but insane not to serve Trump supporters

Sarah Sanders, Mike Huckabee's daughter and Trump's spokeswoman, was politely asked to leave the Red Hen Restaurant in Lexington, Virginia. And she politely stood up and left. Even later, she reacted in a way I find impressively modest and restrained:

Yes, the expulsion says much more about the owner or staff than about her.

Trump has supported his spokeswoman by making you think about the possible dirt in the restaurant that should be more important for the owner than the hypothetical "dirt" of the consumers:

She was harassed basically for being a prominent Trump supporters – but about 1/2 of Americans feel to be almost as strong supporters as she does, they just didn't get her job. This 1/2 of America is not deplorable in any way. They're largely the kind of people who have built America and its fame.

Nima on the end of spacetime

...and arrow of time, quantum foundations, and other things...

David Barrera sent me a link to a five-day-old lecture by Nima Arkani-Hamed at SLAC, the Stanford's linear accelerator center:

If you had doubts, the host is Michael Peskin, a co-author of a very widespread quantum field theory textbook. Nima talks about the demise of the spacetime, simplification in QFT, amplituhedrons which turn scattering amplitudes into high school geometry volumes, and other things.

He formulates it in such a way that I would agree with almost everything but I still feel that there's a potential tension or contradiction with what e.g. Juan Maldacena says on the other side. Nima thinks that the disappearance of spacetime notions as precise ones is "mandatory" – while Maldacena (and perhaps Witten, Seiberg, and others – and maybe me) – thinks that it's just "possible" to suppress the spacetime language to construct a different, equivalent description. But with some good enough stuff – degrees of freedom – that are placed in the spacetime (perhaps including extended objects like strings and branes, bilocal objects such as wormholes, and other things), it may very well survive as an exact concept, too.

It's 2018 and Merkel et al. are still incoherent on migration

Some leaders of the EU member countries (16 countries) gathered in Brussels yesterday in the afternoon. Four days before a more official summit, they were debating how to improve the policies towards exotic migrants that keep on arriving to Europe – although the rates are low these days, about 1/2 of those recorded a year ago.

No leader of the Visegrád (V4) countries has attended (and neither have the British islands, Baltic states, Cyprus, and Portugal). The spokesman for Macron said that the V4 leaders were "boycotting", in order to make things sound more dramatic. But there's no real justification for such a dramatic language. The leaders just agreed not to attend because the presence was in no way mandatory and folks in V4 generally expected that the summit was designed to promote some "solutions" that V4 considers unacceptable – like the quotas for the whole EU. So the costs exceeded the benefits and they just didn't think it was a good idea to attend the not really standard event. Why would one call it a "boycott"? If you just turn down the offer to sleep with a homeless man on the street, do you call it a "boycott"?

Moreover, the summit was likely meant as a tool for Merkel to save her career domestically – in a few weeks, Seehofer's Bavarian CSU may leave her coalition unless she does something against the continuing influx of migrants to Germany from its neighbors. And the countries that didn't attend don't find the salvation of Ms Merkel to be a priority.

On Saturday, the French leader issued a threat to all European countries. If they won't satisfy him on migration, he will take the money from them. I think that for them not to look like ludicrous clowns, French leaders should avoid similar megalomaniac claims and threats, especially when they're standing 10 miles from Waterloo (which is where Brussels is). Do you know what happened in Waterloo, Mr Macron?

Slow bottom-up HEP research is neither intellectually challenging, nor justified by the null LHC data

Ben Allanach has been a well-known supersymmetry researcher in Cambridge, England whose name has appeared a dozen of times on this blog and he wrote a guest blog on ambulance chasing.

Because of his seemingly bullish presonality, I was surprised by an essay he wrote for Aeon.Co a few days ago,

Going nowhere fast: has the quest for top-down unification of physics stalled?
The most nontrivial statement in the essay is
Now I’ve all but dropped it [SUSY at the LHC] as a research topic.
He wants to do things that are more bottom-up such as the bottom mesons (a different bottom, the Academia is full of bottoms). I find this description bizarre because SUSY at the LHC is a good example of bottom-up physics in my eyes – and the bottom mesons seem really, really boring.

Hansen's testimony: 30th anniversary

Tomorrow, it will have been exactly 30 years from the day (June 23rd, 1988) when James Hansen gave a testimony before the U.S. Senate. For the first time, the American politicians were told by a "mainstream looking" active scientist that the global warming would kill us unless we dramatically change our industries and society.

As a professional propagandist, James Hansen chose a blisteringly hot day in D.C. The temperature went up to 98 Fahrenheit in the U.S. capital. He was sweating like mad. The Weather Underground predicts the high temperature 73 F for today and 86 for tomorrow – a cooling by 27 or 14 Fahrenheit in 30 years, respectively.

The New York Times have announced that an expert told the Senate that the global warming had begun. Well, there was nothing special happening to the climate in 1988 or any similar year but something has begun on that year: The global warming hysteria among the mainstream Western politicians and journalists.

The year 1988 was really essential for the birth of that pseudoscientific movement. While James Hansen – formerly a decent atmospheric physicist analyzing the conditions in the atmosphere of Venus, among other things – has made a big impact in the U.S, the U.K. climate alarmists successfully globalized their panic and promoted their national organization to a global one: the IPCC was founded in 1988, too.
