My father discovered it in March: Imunor is a Covid miracle drug

Only a small fraction of mankind has belonged to the Covid risk groups. My father (*March 1948) was surely among them, however. His immunity system has a major defect (a whole line of white blood cells or something else is completely absent, probably the whole transfer factor) and he has seriously struggled with flus many times in his life. Update: He suffers from the deficit of IgA.



My dad contracted Covid-19 during the most likely recent week (the latest peak week), on March 7th, almost certainly from a dude who was 25. Two days later, before any symptoms, he got his first Covid jab (which probably didn't hurt), and symptoms occurred a few more days later. He said that he was (nearly?) unconscious for a while and it was bad etc. It sounds impressive but I have heard the same things from him when he was referring to flu.

Criminally futile lockdowns: Delta will spread in Australia like fire

Delta has \(R_0\approx 8\) and you simply shouldn't try to prevent the spreading of viruses like this

Several countries or regions have had some (temporary) "success" in avoiding any substantial Covid wave. Most of them are gone; there is no "almost Covid-free" country in Europe.

In late October, I was comparing Brazil and Argentina and a Koen worshiped Uruguay that was almost Covid-free. I told him good luck, I don't think it's sustainable, and of course, I was right. In April and May, Covid exploded in Uruguay which became one of the most Covid-active countries in the world – simply due to the lack of natural immunity from the previous infections – and headlines e.g. in Nature currently say Why Uruguay lost control over Covid.

The correct answer is that any densely populated country that can't completely isolate itself or its citizens is guaranteed to go through a heavily infectious new disease at some point and any suppression seen up to some moment is at most delaying the inevitable.



Are there other examples? North Korea is a nearly perfectly isolated country and it murders everyone who is positively tests (it would be interesting to see whether Kim or his relatives would get an exemption from this progressive policy). So maybe they have a chance to keep the infections near zero, assuming that their production of bullets is fast enough.

An obvious formerly democratic, rather isolated country that somewhat credibly wanted to remain nearly Covid-free was Australia, 25M people.


The global Covid statistics page shows just 30k cases in total and 900+ deaths in total. Despite the almost complete absence of Covid in that continent, Australians have been forced to stay much of the recent year in draconian restrictions, just like countries with a Covid epidemics. Melbourne has had at least 3 long very hard lockdowns. Can these policies keep Australia Covid-free?

A huge tornado visited Southeastern Czechia

At night, a big tornado has appeared in the Hodonín area (near border of the Hodonín and Břeclav districts, see Mapy.cz), South Moravia (Moravia is the historically distinct 40% of Czechia in the East). You should check some videos including this viral one or at least the Google Images. Several people have died, hundreds were injured, some six villages were partly destroyed, especially the village name Hrušky (Pears), one-half of the Hodonín zoo was flattened, some hundreds of cars may be gone, and more. My sympathy to the affected ones. If you want to send some money to relevant charities, as I did, I can give you some coordinates (e.g. explain the DMS).


The driver at the beginning got the idea to put the car in reverse. The narrator uses several justifiable obscene words but the Moravian dialect is otherwise so formal, especially because they avoid the informal Bohemian endings of the adjectives (Moravian dialect and formal Czech: Tornádo je vysoké. Bohemia: ... vysoký).

As Wikipedia can tell you, a tornado is a rotating column of air which often damages things. The intensity is measured by the (updated) Fujita scale. The Czech tornado may have been F2 but it may have been F3, too (80% of U.S. tornadoes are at most F1 but there are F4s, too) and an expert named Michal Žák talks about F4 (300 to 400 km per hour). Update: Dagmar Honsová says that the speed didn't surpass 219 km per hour, so it is far from an F4. The Southern U.S. get many more tornadoes than all of Europe combined. The reason is that North America is a large continent with no mountains separating North and South.

All true Europeans root for Hungary, a beacon for our values and a target of an insane PC jihad

Because the moral integrity of the children is under an increasing attack through the exponentially growing indoctrination by lies, the decadent culture, and anti-Western sentiments spreading in the countries that used to be called the West, the nations where the sane majority keeps their control over the essential events need to increasingly protect themselves.



Sometimes along with Poland, Hungary became the Old Continent's main fortress that defends the European values – much like half a millennium ago when Polish and Hungarian troops were the most important ones who protected Europe against Turkish (and Islamic) invasions. The most recent bill that Hungary has easily adopted has a simple basic purpose:

It became illegal to show homosexual or transsexual content to minors which applies to explicit visual content as well as content that would promote these sexual orientations and habits.
The Czech prime minister apparently finds this sentence too complex so he has announced that he will need to talk to Viktor Orbán for some time in order to understand it. You're not exactly a thinker-in-chief, Mr Babiš, if you really don't understand what is going on.

Calculation of \(\zeta(4)\)



A song that is closely related to Zeta.

This is a simple continuation of the calculation of \(\zeta(2)\). Here we will calculate\[ \zeta(4) = 1 + \frac{1}{2^4} + \frac{1}{3^4}+ \dots = \frac{\pi^4}{90}. \] This sum appears in the simplest calculation of the Stefan-Boltzmann constant, a coefficient in front of the power of temperature that determines the total energy radiated by the black body (the integral of the Planck curve over frequencies). Note that \(\pi\approx 3.14\) is just a bit smaller than \(\sqrt{10}\approx 3.16\) and when I was 6, I thought they had to be equal because Mother Mathematics wouldn't produce two irrational important numbers that are this close to \(3.15\). ;-) So \(\pi^4\) is almost \(100\) and that over \(90\) is just a bit higher than one, as required.

Tetrahedron instantons, Magnificent Four, and the mother of all random partition models

The most interesting new hep-th arXiv paper today is the DESY-Rutgers-Beijing work

Tetrahedron Instantons
by Elli Pomoni, Yan, and Zhang. Instantons are localized configurations in the Euclidean spacetime (they are also localized in the Euclidean time, in this sense they live at an "instant", and that explains their names) and as local extrema of the path integral, they contribute to the transition amplitudes in Feynman's approach to quantum mechanics. The contribution is typically nonperturbative at small \(g\), scaling like \(\exp(-C/g^2)\) at least in the simplest cases.



In gauge theory, we have the simplest or "real" instantons in which the field strength is self-dual but arranged in a topologically nontrivial configuration that makes its magnitude decrease away from the center of the instanton. In string theory, there are other instantons that may be made of strings and branes, not just fields (gauge fields).

Why the Bitcoin bubble is a left-wing cult

The Bitcoin trades around $29,000-$31,000 again (and the price dipped below $29,000 an hour ago); the Chinese ban on miners (plus the death cross) have helped a bit to drive the Bitcoin price closer towards the fair price (known as zero). It seems like a good time for some explanations why I consider the builders of the Bitcoin bubble to be a left-wing spiritual organization, not just a generic group of morons. Here are the main eight reasons.



1. Hatred for commercial banks, loans, shortsellers, diverse capitalist activities

The members of the Bitcoin cult are often very open about the fact that they hate banks – commercial banks, central banks, and the activities that these vital institutions are doing. The Bitcoin cultists are standard anti-capitalist leftists who think that the banks are evil, capital is evil, lending, borrowing, and interests are evil, and shortselling is even more evil. They don't understand that all these things have played and still play an existential role in the economic progress of mankind. Their idealized Bitcoin society is just a version of the communist society where things like banks have been eliminated and banned.

Calculation of \(\zeta(2)\)

This post is just an irrelevant pure fun celebrating the release of MathJax 3.2.0 which replaces the version 3.1.4.

The most visible improvement of the new version (which is used to make \(\rm\LaTeX\) nice on this website) is the "lazy typesetting" which guarantees that your device doesn't waste time with printing the equations that aren't seen right now. Consequently, the typesetting becomes an order of magnitude faster; check the blog post about the Euler characteristic as an example. And it has already been fast for quite some time.

Let us pick some "elementary but not quite elementary" calculation in the parts of mathematics that are important enough for a physicist. Among the few hundreds that a theoretical physicist should be able to produce when he is woke up at 3 am, let us pick the calculation of \(\zeta(2)\) (the Greek letter is called zeta, the function is the Riemann zeta function). OK, \[ \zeta(2) = 1 + \frac{1}{2^2} + \frac{1}{3^2} + \frac{1}{4^2} + \dots \] Is there a closed expression for this sum? Numerically, you may find out it is close to \(1.6449\). Yes, most of you know that it equals \(\pi^2/6\), pi squared over six. The very fact that the sum may be expressed in terms of the most famous transcendental number, the ratio of the circumference and the diameter of a circle, may be considered impressive by itself. But once you know a proof, or at least a proof of similar identities, you realize that \(\pi\) is obliged to reappear and mathematical problems such as one above are solvable, integrable, or "trivial" in some sense, so a solution in terms of well-known constants has to exist.

Delta variant of Covid-19 strictly IS a common cold virus

Since the beginning of the Covid-19 era, there has been a battle on "whether it is right to compare Covid-19 to the flu". Of course it is. It is a totally analogous disease. Because Covid-19 was really new and the world population really lacked immunity, the virus could have spread to a much higher fraction of the world population and the case fatality rate was correspondingly higher because the individuals had no defense at all. So 0.05% of mankind has died (4 million) which is still a tiny fraction.

After a great majority of many nations have obtained (or are obtaining) either the natural immunity or the immunity from a vaccine, the virus is either destined to go extinct, or to mutate, establish some co-existence with the people who are (partly?) immune, and become a strict counterpart of the flu or the common cold that may regularly reappear.



Taken from the article: "The fun is over. The genuine men's little cold IS a serious problem, a physician claims." Note that the "little cold of the genuine men" (chlapská rýmička) is often used by Czech women to mock men who are never seriously sick but who complain about minor diseases. However, a 2017 Canadian research showed that (similarly to Covid-19) men are more likely to have complications out of these mundane diseases. Nature discriminates against the men again.

A few months ago, the Covid hysteria has mutated into a special form, the hysteria over Covid variants. Indeed, new variants have prolonged the disease and dying by two months or so (some variants were more contagious, others were partly circumventing the immunity created by older variants) but they haven't changed the big picture. What is happening now, especially in the U.K., is just amazing. And I don't mean any medical events, I mean the propaganda and policy events.

Left-wing "virtue signalling" no longer consists of credible signals according to signalling theory

It is us who is actually virtue signalling today!



Some years ago, I have participated at and especially listened to numerous high-brow discussions about signalling theory. Several fellow Harvard Junior Fellows did this segment of general biology at the world class level so I couldn't have escaped. Richard Dawkins was among those who have participated in the discussion whether the signalling should be considered an attribute of individuals, groups, genes, or species, and many other "details". What am I talking about?

Animals (and humans) communicate in various ways and they need to send the information to their prey, to predators, to potential or current sexual partners, and more. "I am great" is a very typical message that needs to be sent but some individuals may be incentivized to lie and cheat and send this "information" even when it is untrue. One of the core tenets of signaling theory is that the best and strongest (or most credible!) signals are the costliest ones.

Widespread defense of "1+1 isn't 2" means that the whole education system has collapsed

Would-be fancy apologists for the woke insanity are wrong about everything

Back in 2017, the following wonderful satirical minifilm was released:



Danny, a boy who struggled with math, wrote that \(2+2=22\) into a test. His old-fashioned teacher, an older woman, did everything she could to professionally teach him that \(2+2=4\) but it was hard. Instead, the spoiled brat's wrong answer was increasingly violently defended by Danny's dumb parents, the teacher's dumb principal, activists on the street, and an Orwellian legal committee of the city hall. The plot ended with a happy end. When the teacher was fired, she got a compensation of $2 thousand for the last month plus $2 thousand for the present one. She could use the new standards to claim that the total is $22 thousand. ;-) She would be even richer with $20002000 dollars.

Technical analysis only "works" as a self-fulfilling prophesy

The Bitcoin price is apparently likely to exhibit the "death cross" within a week. It is a bearish sign that makes people expect a significant collapse of the Bitcoin price. If you click, you will learn that a death cross is the situation when the 50-day moving average is above the 200-day one but they are approaching one another and the "death cross" moment is when the short-term, 50-day moving average drops below the long-term, 200-day one.



It tells you that "the recent prices are getting lower than the historical prices" so we're going down. The opposite situation is a "golden cross" which would be a bullish sign, a sign expected to induce an increase in the price.

Is this rule correct? Does it follow from pure mathematics? From the pure laws of economics? From the laws of physics? Or is it a counterpart of astrology? Indeed, these methods are called "technical analysis" (and these astrologers – believing that you may predict the future of a graph just by seeing patterns in the past – are called "chartists") and the first paragraph of the Wikipedia page says that "many Academics consider technical analysis a pseudoscience". Well, of course, I largely endorse that group. But things are more subtle and I would be absolutely dissatisfied with a simple one-word judgement here.

There won't be any nontrivial Fall 2021 Covid wave in CZ, UK, most of Europe, US...

I can guarantee it for you, insure you

The numbers of new positive tests have been dropping in Czechia since early March and this time, it is obvious that this quasi-exponential decrease is the last one. Technically speaking, it is right to say that Czechia has enjoyed the herd immunity (towards the latest, most contagious, variants) since early March (even though the daily casualties were huge and the fraction of infected surely counted as an epidemics) because the quasi-exponential decrease has been statistically guaranteed since that moment because \(R_0\lt 1\) was true, even with relaxed restrictions. But only these days, the number of deaths has dropped to "roughly one or two" and the herd immunity has clearly done an overwhelming fraction of its hard work.



Dr Zdeněk Hostomský, the director of the Institute of Organic Chemistry and Biochemistry of the Czech Academy of Sciences (and a former boss of cancer research at Pfizer!), became the latest competent Czech scientist who has communicated the vital scientific knowledge to the media. For months, he has emphasized that the lockdown didn't work and should have been terminated.

In more recent interviews and essays, he says that lives may still be saved by vaccinating the people in the risk groups (my estimate is that we would have had 40,000 casualties instead of 30,000 if there had been no vaccines; but now, only dozens of lives will be saved by new vaccinations) and it's a good idea to spend energy by persuading them. Also, he says that in the summer, there will be almost no Covid virus in Czechia because we've achieved some sort of herd immunity that will show its muscles.

Why some stopped hiring Ivy League alumni



Russell Ronald (R.R.) Reno III, the editor-in-chief of First Things, an intellectual Christian magazine, wrote a nice essay for the Wall Street Journal,

Why I Stopped Hiring Ivy League Graduates.
A decade ago, he would still consider Princeton, Harvard, and similar graduates as top candidates for a job (of writers). But it has changed. These days, some are woke; some are self-important; but more importantly, most have been stripped of role models and trained to be silent when it matters. I couldn't agree more.

M-theory on \(G_2\) manifolds, heterotic strings, oceans, climate, and carbon



This unattractive Titanic-like building will become Czechia's tallest building (135 meters) and will be built just miles from the Prague Castle, in order to make us remember that the "architect" was impressed by the climate hysteria and willing to promote the lies about the climate.

Among the new hep-th papers that were released today, five mention a "string" in the abstract. I think that the following paper is the most interesting one:

Non-Perturbative Heterotic Duals of M-Theory on \(G_2\) Orbifolds
It's a nice paper that could have been written during the Duality Revolution in string theory of the mid 1990s but it waited up to 2021. It is a six-or-seven-dimensional or \(G_2\) counterpart of the statement that the \(T^4/ \ZZ_2\) orbifold is a special case of a \(K3\) manifold; and that the \(K3\) manifold may degenerate into two "half-\(K3\)" manifolds that are connected by a three-toroidal throat (times a line interval with irregular ends).

The FBI may very well possess most Bitcoin private keys, other passwords in the world

The U.S. and China are among countries whose governments are planning to restrict the cryptocurrency activities. On the other hand, a confederacy of 25,000 gang members known as El Salvador claimed to adopt the Bitcoin as an official currency (these criminals have been using crypto for a long time so it's not really news). Another great friend of the U.S., Iran's mullah-in-chief, has also called for the legalization of the Bitcoin (Iran and North Korea have used Bitcoin to circumvent sanctions etc., too). Meanwhile, Donald Trump said that the Bitcoin seemed like a scam – and a thing that wanted to challenge the global dominance of his preferred currency (it has a name imported from the Czech language). Meanwhile, the FBI did something cool that drove the Bitcoin price below $32k again.



Hackers have hacked and encrypted files on the Colonial Pipeline servers. The breach was harmful, oil stopped flowing, and the company has actually paid some $4 million in Bitcoin in ransom. The files were decrypted (not all extortionists are this honest!) and the oil flows were resumed.

That ransom came to dozens of wallets but... the FBI conquered $2.3 million, a majority of the ransom, because it acquired the private key – the longer gibberish sequence of digits that is needed to send funds (to "sign" the electronic confirmations that the owner wants to send something) – from the largest Bitcoin wallet. How is it possible? It should be impossible (in any realistic timeframe) to calculate the (longer) private key from the publicly known data – which seems to be just the public key.

Lab leaks, bioweapons, and gain of function research

Many TRF readers recommend this Nicholas Wade's article about the artificial origin of the virus

From the beginning of the Covid era, it looked very likely that the appearance of the new virus in Wuhan has something to do with the biological lab over there – which has investigated coronaviruses and bats, among other things. The accumulation of two such things in Wuhan could be coincidental but the geographic evidence is rather strong that it was not coincidental.


Czech molecular geneticist Ms Soňa Peková was among the first ones, if not the first one in the world, who presented technical arguments that the virus was not quite natural. Unsurprisingly, she was attacked by the (clearly ideologically driven) far left "journalists" and similar folks who know less than 0.1% about genetics compared to what she knows. I don't quite understand these technical arguments. But it is clear that there are many levels of "human intervention" that could have "helped" to spark the epidemics. It could have been a natural virus that was "just" nontrivially isolated, reproduced, and leaked. The leak could have been an accident or not. An existing virus could have been genetically modified and the degree of modification could be minor or substantial, and so on. I don't think that such adjustments to a virus are a cutting-edge science today. The virus could have also been intentionally modified so that it is more harmful to the whites and blacks and less harmful to the East Asians.

There are lots of uncertainties – and there are even greater uncertainties about the motivation behind these acts if there were any.

Predators, hawks are more intelligent than their prey

Left-wing "virtues" are not positively correlated with the intelligence at all

I had a fun chat with a right-wing friend that was dedicated to some recent battles on the Czech political scene (Klaus vs Soros' conspiracy theorists; Babiš vs Pirates), and related events. And I couldn't overlook his assertion that, roughly speaking

a person's preference for non-violent solutions is highly positively correlated with his or her intelligence.
Oh, really? This belief made me worried (and upset) because the conflation of intelligence and left-wing and PC beliefs is clearly one of the most fundamental lies that the New Left is using to accelerate the putrefaction of our civilization. The extreme leftist scum is increasingly filling the media, schools and other institutions with people who aren't good craftsmen according to the old-fashioned meritocratic standards but who are sufficiently convenient for (or compatible with) the left-wing lies. Such as lies about the equality of everything and lies about the reliable superiority of the would-be "oppressed" groups.



The lie about the equivalence of leftism (or snowflakeness or related "left-wing virtues") with intelligence has been a powerful tool designed to increase the influence of degenerated leftists for a simple reason: in its collective wisdom, the society realizes very clearly that the intelligence (and the intelligent people) is a virtue, something that is needed for a nation's (or another group's) successful competition with others and for the sufficiently glorious progress of mankind as a whole. When people fail to distinguish between the intelligence and the snowflakeness, the abused and misdirected collective wisdom will have the effect of promoting the snowflakeness as well, and that was indeed what we were observing in recent decades.

Soviet loan fake news: Václav Klaus Institute responds to a non-apology

IVK's response to the reaction of the editors-in-chief of HN and Aktuálně.cz regarding the false accusation of Václav Klaus of sending 1.3 billion US dollars to the USSR

JIŘÍ WEIGL
PETR MACINKA

Dear editors-in-chief,

We are disappointed by your response to our public letter and request for an apology for fabricating a conspiracy theory about a secret loan to the USSR just before November 1989. The fact that you are unable to acknowledge the misconduct of the media you control, and dare to apologetically call blatant lies "media shorthand", is an example of arrogance and hippopotamus [thick] skin that is contrary to any elementary journalistic ethics.

Steve Koonin responds to an article in SciAm

SciAm rejected to publish the following response by Dr S. Koonin
Koonin responds to a Scientific American article by Oreskes et al.

Scientific American has published a criticism of me and my recent book, Unsettled. Most of that article’s 1,000 words are scurrilous ad hominem and guilt-by-association aspersions from the twelve co-authors. Only three scientific criticisms are buried within their spluttering; here is my response to each them.

12 or 100 totalitarian pseudoscientific authors against Steven E. Koonin

Steven Koonin has released his new 240-page-long book Unsettled where the physicist and a (former) Obama Administration official explains why the climate change talking points are misleading propaganda. It seems to be a bestselling book and the average rating from the 400+ reviews at Amazon.com gives the book 4.8 stars.

Steven E. Koonin got his undergrad degree at Caltech, his PhD from the MIT, and he has been a theoretical physicist for decades. His papers include those about nuclear physics (including the reactions in the Sun), many-body physics, computational physics, biophysics, and physics of renewable energy sources, among other things.
