Science Magazine, climatologists: models overstate temperature changes by a factor of two or more

Dr Roy Spencer's 2014 page. Similar graphs showing that almost all the models simply overstate the warming have been published by climate skeptics before 2014 as well as after 2014. It's clear that the longer time the climate modelers follow a flawed methodology that clearly overstates the warming rate, the larger the deviation between the models and the reality becomes – and at some point, the climate modelers won't have the stomach to defend models or a model methodology that is clearly flawed. Note that Al Gore and the IPCC got the Nobel Prize in 2007, it is almost 14 years ago. For that time, median models predicted over 0.4 °C of warming but we only observed 0.2 °C or so.

Bill Z. sent me a remarkable pair of articles by Paul Voosen, a staff writer, in the Science Magazine:

U.N. climate panel confronts implausibly hot forecasts of future warming
New climate models forecast a warming surge
It has been eight years and... the IPCC (the Intergovernmental Panel for Climate Change) will release its first new assessment since 2013. What has changed since 2013? Well, nothing detectable has changed about the climate – Voosen has the duty to start his first article by writing that the Armageddon has escalated, almost all the ice has disappeared, the end of the world is very close now. Nice. It is ludicrous but no longer surprising. What is surprising is what he writes after that.

EU's war on humor

Willie Soon sent us an incredible document that is hosted on the European Commission's server and labeled as a pretty official document of the European Commission (i.e. The European Union) and its "Radicalisation Awareness Network"

It’s not funny anymore. Far-right extremists’ use of humour (PDF, 18 pages)
The first sentence boldly proclaims:
Humour has become a central weapon of extremist movements to subvert open societies and to lower the threshold towards violence.
After 2+2=4, humor had to be finally identified as a tool of racist sexist transphobic homophobic torture by climate deniers, too. It's coming.

Just years ago, you would be sure that something like that had to be a parody. Everyone would agree that only a true pile of human crap may overtly denounce humor. However, the times have changed and a simple background check of the two authors makes it almost certain that this document is meant seriously: 18 pages of garbage that is comparable to the first sentence above.

Could a Czech Covid-positive Olympic athlete need oxygen?

Not really.

OK, Czechia has 10.7 million people. Assuming the thresholds that are used for flu, the Covid-19 epidemics ended sometime in April or May and for all practical purposes, there has been no Covid-19 in Czechia for a month. The daily cases, hospitalizations, daily deaths etc. are 98.0%-99.7% below the most recent March peaks. In total, 30,000 lives were "ended with Covid-19" according to the official statistics. Every year, about 112,000 Czechs die without Covid-19.

Now, the Czech Olympic team is composed of 116 athletes. 80% of them have been vaccinated against Covid-19 which is a higher percentage than 60% in the general population: athletes are really being pushed into this ritual which still "isn't quite mandatory" but it's close to being mandatory. A special flight took 40 people, mostly athletes but some members of the support staff, to Tokyo around July 20th. A day later, we already discussed their positive tests. The Japanese have more sensitive PCR tests than we have. None of the people have any symptoms. As far as I can say, every single one is a false positive.

Let's divide the European Union

By Dr Jiří Weigl, July 22nd, 2021

Last week's publication of the European Commission's plan for a green "great leap" in the holy struggle to save the climate has definitively confirmed that the gulf of opinion, ideas, and interests between the EU's West and its post-communist East has reached an insurmountable dimension.

Will the Green Deal destroy the EU's destiny?

Commentary by Alexander Tomský

Since the fall of the Berlin Wall and the communist empire, the West has been pushing two ideologies that normal everyday people cannot believe and wonder how it is even possible that they are promulgated by educated people, at least in the sense of people with university degrees. Few suspect that this is a hidden disease of the speculative intellect.

Steven Weinberg: 1933-2021

Virasoro: Yesterday, on the same day, Miguel Virasoro died as well: news. He was an Argentine-born Italian pioneer of string theory; the closed-string tachyonic "Virasoro-Shapiro amplitude" is named after him (Shapiro was my instructor at Rutgers) and so is the "Virasoro algebra".
Tragically, Steven Weinberg died in the ICU of a local hospital last night (via his colleague Coker), after weeks of hospitalization. He has been a giant of theoretical physics.

I took this picture (of Steven Weinberg with the wife, of Sheldon Glashow) during Sidneyfest in 2005 in our Harvard Society of Fellows' dining hall (inside the Elliot House). Both of us were already former junior fellows at that moment. I can find about 5 other pictures of Weinberg that I took at various moments. When I was giving a talk in Austin, Weinberg was sitting next to me during a dinner that he formally organized for me. My Erdös-type collaboration distance was 3, e.g. Motl-Dine-Witten-Weinberg.

Weinberg shared the 1979 Nobel Prize for Physics with Sheldon Glashow and Abdus Salam. While the first two were classmates since the childhood, the third dude was arguably the greatest Muslim theoretical physicists of all times.

Excessive fears are worse than Covid-19

A newspaper interview with the Czech expresident Václav Klaus

You're asking the government to stop scaring citizens. What do you think it should do?

The government should stop worrying about us, it should let us live our lives normally, it should allow us to choose our level of risk, our level of responsibility towards our neighbours, towards the world. Everyone should decide for themselves how to behave covidly. It is worthless for the state to advise us, and to advise us as stupidly as it has done so far.

Did Covid shorten Czechs' life expectancy by one year?

No, it was just around 0.04-0.27 years, the decrease was temporary, and by now, Covid-19 has led to an extra (albeit tiny) increase of our life expectancy on top of the trend-like increase!

Dear Prof Klaus,

thank you very much for your wonderful message and your question whether it's possible, as the Czech biostatistician Mr Ladislav Dušek claims in a daily, that Covid has shortened life expectancy of Czechs by one year ("in 2020"). It is an excellent question that should be seriously discussed, instead of irrelevant factoids about the number of "cases" in this or that place which people are still fed by the media, aside from the repulsive needles and deceitful arguments in favor of needles.

First, I must say that the Czech phrases "střední délka života" and "naděje dožití" ("average length of life" and the "chance of a long life", literally) are considered exactly synonymous in Czech; both are translated as "life expectancy" (click to get the Wikipedia entry, I don't claim that it's the best source I could link to).

There is really only one quantity that may express "how much life is left for an average person". However, one must realize that the word "average" means that we must specify the group that is being averaged (a simple arithmetic average with equal weights) such as the Czech nation. If we choose a subset of the Czech nation, it will have a different life expectancy than the whole nation. In particular, the "remaining life expectancy" will be shorter for older cohorts (groups of people according to an interval of age); but the expected or average age at death (which is the current age plus the remaining life expectancy) is actually longer for the older cohorts because they have already passed a test. It is obvious for those who are 96 because they are guaranteed to die 96-year-old or older; while the average Czech is not guaranteed that outcome of Fred Singer's yet. We must distinguish the remaining life expectancy and the total life expectancy; they simply differ by the average current age of the group we try to describe.

Will the people rise up against the EU?

Czech expresident Václav Klaus darkly on the car ban and the protests: 'It fizzled out into nothing'

Mr President, as a long-time campaigner against green bans and restrictions, what do you think of the European Commission's rather bold 'climate package'?

This climate package is not bold. It is stupid and nonsensical. It is unrealistic, and if it were to be implemented, it would be a completely destructive package. Completely destructive to the lives, freedom and living standards of the people of Europe.

If the package is fully implemented, what good will it do for our planet, globally speaking, if we in the EU reduce carbon emissions by 55% by 2030 and become 'carbon neutral' by mid-century?

That this package can do any good for the planet is something only green activists, only the advocates of the utterly unsustainable doctrine of climate alarmism, can think. Only people who believe in an immediate linear or even exponential relationship between the amount of CO2 in the atmosphere and the average global temperature. I am not one of these deluded individuals who have managed to garner such absurd media coverage. Man's role in the evolution of global temperatures over the long term is completely negligible. Moreover, CO2 has already played its potential role in influencing temperatures. The intention of carbon neutrality is an anti-human policy. It has almost no connection to temperature.

"The pure joy" $$E_8$$ SUSY toroidal orbifold TOE

In the early 1970s, supersymmetry (SUSY) was discovered. By the end of the decade, it became a vital tool in model building. By 1981, the supersymmetric standard model was mostly understood and seen to be superior to the non-supersymmetric standard model in many respects.

Everybody is already in Mexico, Michal Tučný 1986

Grand unification (GUT) has been around from the early 1970s as well. And in 1985, SUSY GUTs were embedded in the first semi-realistic model that also included quantum gravity, namely the $$E_8\times E_8$$ heterotic string theory. $$\ZZ_3$$ orbifolds of tori have always been the "simplest" examples of Calabi-Yau threefolds that the unobserved 6 dimensions (among the 10 dimensions in total) could take.

In these new papers, a Mexican-Portuguese-Swedish team (Aranda, de Anda, Morais, Pasechnik) constructs the simplest, non-gravitational combination of the "too good to be an accident" traits of heterotic string theory on the toroidal orbifolds:

AdAMPmini: A Different Take on $$E_8$$ Unification

Evolution, deterioration of the world's thinking about the deepest stringy ideas

A paper on Monday: The first paper was posted in the initial second of the day (showing their pride) by a Munich triplet. They develop a machine learning technique to guess correlations in the string landscape and look for viable vacua. With clever techniques, it could even be possible to find the right vacuum in a googol-like set. Anti-string simpletons don't get such things because their extremely modest brains can only understand brute force (which must be done by others because they don't possess it, either).
David B. specifically asked me to rewatch this video

especially the part between 20:45 and 48:35 (in the first 20 minutes, both Green and Schwarz mostly review their important work around the 1970s). It is a discussion of selected string theory big shots at the end of "String 2021" which formally took place in Sao Paolo but which followed the format of an "online conference" of the Coronazi era. I don't think that Jair Bolsonaro would agree with this kind of a "conference in Brazil". Participating in the discussion were Gentlemen such as Seiberg, Witten, Green, Schwarz, Strominger, Vafa, Yin, Harlow, Berkovits, Ooguri, and a few more.

Cyril and Methodius were at the birth of Slavic education

The brothers were exceptional personalities, they excelled in insight

Commentary by Tomáš Zdechovský, a member of the European Parliament, KDU-ČSL
The arrival of the saints, who were at the origin of Slavic education, has been celebrated on 5 July only since 1863, when a thousand years passed since their arrival in Great Moravia. This day was set by Pope Pius IX at the request of the then Archbishop of Olomouc, Bedřich of Fürstenberg. It was first used in Bohemia, Moravia, Croatia and Slovakia. Later, the feast was extended to the entire Roman Catholic Church. Until then, since the time of Charles IV, the arrival of Saints Cyril and Methodius was commemorated on 9 March. Only the year 863 is certain, when the two siblings were sent to Moravia by Emperor Michael III. Their arrival is recorded in the calendar as a public holiday - the Day of the Slavic Heroes Cyril and Methodius.

However, March was not a suitable time for the celebrations, as the date fell during the Lenten season. Among the reasons for the move, apart from the unsuitable time of year and liturgical time of the earlier date, was the growing importance of the feast of Jan Hus in the Czech Republic, which falls on 6 July. However, we do not know the exact date of the arrival of the Slavic saints. In fact, the date of July 5 has no direct connection with the life of Cyril and Methodius, and the Slavic Orthodox Churches have the day of Saints Cyril and Methodius on May 11 according to the Orthodox calendar (May 24 according to the Gregorian calendar), when Cyril and Methodius are traditionally supposed to have come to Great Moravia. As historian Jaroslav Šebek has already mentioned, it has never been established when the Great Moravian prince Rastislav actually summoned the two brothers from the Byzantine Empire to Great Moravia. Some claim that it should have happened in the spring, others, according to his words, lean towards the transition between summer and autumn.

What robust herd immunity does: 4 Czech ICU patients only

Colombia has a 440 times higher fraction of population as serious Covid patients than Czechia

The Czech government sometimes behaved rather sensibly but its overall behavior in the epoch of Covidism has been as terrible as that of the average Western government (in some restrictions, it was saner, in others such as keeping the schoolkids away from schools, it was worse than the average).

Thankfully, in their everyday habitats, the Czech public behaved differently and something like 50% of us never bought the Covid-19 propaganda, remained calm, and used all available tools and cooperation to circumvent most of the unconstitutional restrictions, especially restrictions of the truly basic activities. Correspondingly, at the level of the everyday lives, most of the relevant people behaved normally. That also led to more natural, faster dynamics of the pandemics when it was taking place – and to very robust (mostly natural) herd immunity.

It is herd immunity towards pre-delta variants. The Indian delta variant of SARS-CoV-2 belongs among the common cold viruses. Correspondingly, the $$R_0\approx 5-8$$ and almost all countries with a nonzero presence of this nearly harmless virus are almost guaranteed to see some "growth of delta" – unless all their regions and otherwise sliced subcommunities enjoy at least 80-90% of the immunity rate which most countries simply don't have, especially not among youth where the vaccination rate is generally low (for extremely good reasons).

What matters are the truly sick people and the dead. The most recent 7 daily death numbers on our statistics page say 0,0,0,1,1,1,0. Just 3 deaths in 7 days, 0.43 per day in average. That's way down from the peak, 237 deaths on March 15th, 2021.

CO2 emissions, "cases", ... fanatical leftists love to worship meaningless quantities as measures of well-being

...because they hate decisions by the free people. Money is the only meaningful quantity that encodes the human well-being which is why the leftists love to (overtly) hate money

Despite the persistent denial of this fundamental fact by the anti-science whackodoodles, everything in our Universe operates according to the laws that require mathematics to be accurately enough described.

The distance between the Earth and the Sun is a time-dependent variable, a quantity that carries the units of meters (or other units of length), the temperature of an object may be expressed in kelvins, the duration of a process is measured in seconds, the magnetic field in teslas... There are hundreds of possible SI units for quantities and for each of these unequivalent units, there are several or dozens of "rather different" quantities that share the same unit.

Everything we may measure may be reduced to "observables" $$L_j(t)$$ which are time-dependent. In the times of classical physics, people believed that these observables ultimately evolved according to deterministic laws, namely some differential equations obeyed by functions of time $$t$$. In quantum mechanics, the measured values of all these quantities are random and only probabilities of various outcomes may be calculated (through the probability amplitudes) from the knowledge of the initial state (which is computed from the initial measurements).

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).

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. Monday, June 21, 2021 ... // 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. Friday, June 18, 2021 ... // 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.

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.

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.

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. Friday, June 11, 2021 ... // 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. Thursday, June 10, 2021 ... // 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. Wednesday, June 09, 2021 ... // 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). Tuesday, June 08, 2021 ... // 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

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

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.

A nasty story about the Soviet debt

A newspaper article was recently published that attacks Czech ex-president Klaus and claims that he has secretly lent a billion dollars to the Soviet Union in late 1989 – and the current president Zeman arguably completed the sin by forgiving the debt later.

The statement by the Václav Klaus Institute below demonstrates why the article is a collection of many independent insulting lies. If the Belorusian passenger has committed just 20% of what these Czech pseudo-journalistic aßholes have done, I would have quite some understanding for the special maneuvers needed to remove this writer from the aircraft. Some people are just amazing scum. Their goal isn't just to spread lies about individuals; they want to cripple the society as a whole. And the readers who take this junk seriously must be incredible morons. Even if the statements were right, well, we were still allies of the Soviet Union in late 1989 – and Moscow was transforming itself in a way that was not so far from our transformation. It would still be completely crazy to interpret the events from the perspective of some contemporaries' unhinged Russophobia.

IVK demands a public apology to Václav Klaus from Hospodářské noviny [a WSJ-like economics-focused Czech daily]

PRESS RELEASES, 29 MAY 2021,
automatically translated by the incredible deepl.com

Mr. Editor-in-Chief Mašek,

On Tuesday, 25 May 2021, your newspaper, along with other media outlets of your parent publishing house Economia, launched a targeted campaign of disparagement against President Václav Klaus by printing a lengthy front-page article with the incredible headline "Klaus secretly sent billions to the Soviets after the revolution". It claims, allegedly on the basis of archival material, that the then first post-communist Czechoslovak finance minister secretly sent USD 1.3 billion to the USSR after the revolution, and that this plan was hatched in 1989 by a clerk at the Federal Ministry of Finance (!!!), a certain Zdeněk Rachač, allegedly an StB agent, who was supposedly Klaus's advisor. You have therefore attempted to impose on the reader the view that Václav Klaus was from the beginning a participant in some kind of communist conspiracy and from his first days in office he was consciously and conspiratorially damaging our country.

Leftist groups and symbiosis of unattractive radicals and moderate hedonists

TOP 09 is a small Czech political party (which would probably earn below 5% in the coming elections – but it will get to the Parliament through a larger coalition "SPOLU" [together] that it has joined) which is my country's counterpart of the CDU in Germany: an entity pretending to be conservative which has become a hotbed of the most insane "progressive" (and globalist, multicultural, Russophobic...) far left ideology. The leftists who want to preserve some conservative image often pick TOP 09 as their party. It was formed in 2009 when it separated from KDU-ČSL (the acronym KDU means the same as CDU, ČSL is the Czechoslovak People's Party), a much older party.

It was initially founded by Miroslav Kalousek, a skillful and talented polemicist in the Parliament who later served as a Czech minister of finance and got many awards, and I think that rightfully so. His most important buddy was "Prince" Karl Schwarzenberg, an old repeatedly sleeping Austrian aristocrat who has always emphasized his proximity to the Czech ex-president Václav Havel and who has once served as the minister of foreign affairs.

These two dudes were gradually drifting towards the extreme left, perhaps analogously to Angela Merkel and many others, but the newer generation of leaders such as Ms Markéta Adamová-Pekarová, the current chairwoman, are no longer pretending to have some real relationships with genuinely conservative values any longer. She is (and others are) a copy of the Communist Youth organizations before 1989. But the picture above is that of Dominik Feri, a special case.

A very popular minister is ordered to return

Since the beginning of 1993 when Czechia and Slovakia parted their ways, Czechia has had 23 ministers of health. (I have personally talked to 2 of them, Macek and Špidla.) The average one has apparently survived for 28.5 / 23 = 1.24 years. That's a quickly rotating job, indeed. The Covid-19 situation has already led to the firing of 4 ministers of health: Adam Vojtěch, Roman Prymula, Jan Blatný, and Petr Arenberger.

Vojtěch, a contestant in the CZ American Idol in 2005 (nicknamed "Ken" from "Ken and Barbie" there), was singing on TV again in October 2020. Isn't he a stellar singer? How many ministers of your country could sing this well?

Edwin's understanding of QM: Part IIIa, the principles, Section 1

A mail from Edwin Steiner

Luboš, I finally finished the first part of episode 3 of my QM series. Here's the link.

Episode 3 presents the principles of QM and this first half is about the representation of knowledge by vectors in Hibert space. Operators and their algebra will be the content of the second half. Initially, I had the plan to start with operators right away, as I'm sure we agree that they are the best focus point for a mature understanding of QM. I even recorded a first version of the video doing that but I found it to be pedagogically unsatisfactory due to an excess of forward references, etc..

Sleeping Beauty wakes to a cold April

In 2021, Czechia experienced the coldest April since 1997. Around April 20th, the ranking was expected to be even more extreme but the end of the month just wasn't extreme enough. Surprisingly enough, the precipitation was well below the normal (60% of normal at "most" places) but the middle of May – when the rain in a few days was enough for 2 months – overcompensated that (see some dramatic scenes from Úslava, normally the smallest of the 4 rivers of Pilsen).

In the past, Sleeping Beauty (pictured in her Neuschwanstein am Disneyland des Plagiarism) was discussed on this blog as a key character to explain an elementary misunderstanding of the probabilistic calculus – that seems impossibly hard even for some theoretical physics PhDs.

Innumeracy of public health officials

Due to the utterly sensible, relaxed approach of the common folks, Czechia has had the highest number of Covid-19 per 100,000 people in the whole world. The graph of new positive PCR tests per day looks like this:

Click the picture to zoom in (source). A nicely natural function, right? On the left side, you see a slight elevation which we considered the first (Spring 2020) wave (no excess of deaths existed at that time). The real Covid epidemics only started in October 2020 or so and this main wave has been composed of 3 subwaves. At least the last one exists mainly due to the new variants of the virus (especially one having a higher R0; but also a variant partly circumventing the previous immunity).

The seemingly infinite volume of $${\mathrm{PSL}}(2,\RR)$$ is $$-2 \pi^2$$

And you need just a few short steps to calculate the D-brane tensions from that fact

The today's most joyful hep-th abstract was written by two names that didn't click with me (Eberhardt, Pal; their publication records initiated around 2017 seem impressive) but their affiliation did, the IAS at Princeton (that's a place where Einstein has worked for 1/2 of his career). It's an appropriate place for the authors to work because I am really happy about the paper which is titled simply

The Disk Partition Function in String Theory
and it discusses a theme that I found cool since the high school: many seemingly infinite expressions must actually be assigned finite values. The most famous example is the sum of positive integers$1+2+3+4+5+ \dots = -\frac{1}{12}.$ This identity is important enough in string theory, including the (natural, bureaucracy-free) calculation of the critical spacetime dimension. I've played with some generalizations before I started to submit some serious papers. You may also check a recursive evaluation of zeta of negative integers.

Thirst for dividends and financial illiteracy

I simply had to use the word "thirsty" today for this reason.

My country restarted the capitalist system over 3 decades ago, and it's had centuries of experience with it before 1948. Western countries (in the Cold War sense) have lived in the uninterrupted capitalism for centuries. Nevertheless, it seems to me that only a tiny fraction of my nation – and Western nations – understands totally basic concepts of capitalism such as "the rational reasoning needed to figure out how much you should pay for a stock".

OK, one extreme level of this financial illiteracy is the people's "investment" in stuff like the Bitcoin or Tesla, things that obviously don't have the intrinsic value matching the price – they have no chance to repay the invested money. The people buying into these bubbles resemble a cult. They probably realize that the Bitcoin or the Tesla stock can never pay those $5,000 or$60 per stock in dividends which would justify the valuations. And they don't seem to care because they apparently think that just like sex according to the hardcore feminists, the price is a purely social construct. These "investors" don't have any method to estimate the fair fundamental value. All of them are "momentum traders" – i.e. bad investors – and growing and bursting bubbles is the only thing they can achieve.

EO: Covid-19 tests are sterilized by a major carcinogen

I don't really believe that any of the widespread tests or vaccines are filling the victims with chips or some truly novel timebombs for their health. But I have always found it wise to be worried about carcinogens in various unusual health gadgets.

And a video I just received (Rumble) has explained that the tampons in the Covid-19 tests are labeled "SterileEO". It means sterilized – stripped of the bacteria – using ethylene oxide (a method that has been used for medical supplies for years before Covid-19, of course). Many people that the dude in the video knows have died of things like brain hemorrhage and other things.

EO is isomeric with acetaldehyde and with vinyl alcohol.

"Ethylene oxide itself is a very hazardous substance. At room temperature it is a flammable, carcinogenic, mutagenic, irritating, and anaesthetic gas," Wikipedia adds.

Pump and dump, manipulation

Wizard asked how did I reckon before Elon Musk is sent to jail. Well, I got already used to the fact that increasingly stunning examples of market manipulation are tolerated and I believe that it will get even worse – but it will stop at one future sunny day, anyway.

A comparison of BIG 5 electric SUVs released 2 days ago. Regardless of the price, Škoda Enyaq beats others in pretty much every respect, especially by its range which renders competitors obsolete. On top of that, it is 30% cheaper. Tesla Model Y may at most match the Enyaq but the price is 50% higher than the Enyaq, too.

In March, I discussed fake growth stocks and investments that weren't real investments, like the Cathie Wood ARK Innovation ETF Fund. It is a fund where the financially illiterate "guru" picks the "best" stocks – in particular, stocks of nearly worthless companies that are overpriced by a factor of 10+ and by promoting them (she has useful idiot friends in the media), she makes them overpriced by a factor of 100+ if not 1000+. By growing these bubbles around nearly worthless companies, she has been reporting impressive yields.

Manipulators like that often buy before others, and sell before others, and that is called the pump and dump securities fraud. Well, there are signs that she is forgetting to sell. If you click at the previous paragraph, you will see that the ARKK fund's price went from the peak $159.70 to the current$99.48, a 38% drop in 3 months. Compare it with the general stock indices that are at most 2% below the all time highs and even Nasdaq that is some 7-8% below the all time highs. Has the bubble burst?

European energy prices will go to the Moon

Notoriously enough, Austria organized its nuclear energy referendum in 1978. 50.5% voted against the Zwentendorf nuclear power plant plans and Austria became a hysterically anti-nuclear country, a fact that has often complicated the life of Czechs whose majority loves Austrians. This was an example of a referendum that should have been rigged by the sane people. The tiny edge of the Luddites has had far-reaching, long-term consequences.

Isar Zwo in Bavaria which we visited (as students) in 1992.

Germany remained nuclear (although not as much as France which makes 70% of its energy from the nuclei, and it used to be 80%) up to this nation's hysterical reaction to the 2011 tsunami-inspired glitches in Fukushima. Germans decided to obediently agree with their leaders' decision to ban nuclear physics in Germany. No $${\rm MeV}$$s allowed there; applied nuclear physics was rebranded to just another pseudoscience promoted by the groups that the Germans have the "right" to bully. Well, the moment when the last power plants should be stopped is coming closer.

Mathematics, quantitative attitude distinguishes the human civilization from animals

People have replaced Nature's random "trial and error" method with something a bit more pre-planned, and calculations are needed for those civilized plans

Mr Huml (from the Ice Age) was explaining to Mr Mach that it was a cold age and people had a lot of cold. They often caught a mammoth and ate it with a dill+cream sauce.

In the text about the limits of the ancient Greek "science" and "technology", a commenter named giant claimed to argue that one didn't need any science in the modern sense – founded by Galileo – because one may mention a counterexample, namely bronze. He added:

Somehow people figured out how to make an alloy, without understanding atoms, crystalline structure, temperatures, no chemistry at all.
Cute. Indeed, people could make bronze without any of these sciences. But that's because "making bronze" isn't scientifically difficult – surely not to an extent that would be comparable to the science that is needed to build and/or optimize a steam engine (with a gearbox).

What is bronze? It's an alloy composed of (mostly) copper and also some other metal, typically tin (12-12.5%). However, the percentage is this precise because the Wikipedia editors added this number long after the Bronze Age. ;-) That's a percentage where the alloy holds together. In the Bronze Age, not only the folks didn't know about the 12-12.5% interval. In fact, the tin was often not tin at all. Bronze may also be a copper alloy with aluminium, manganese, nickel or zinc; or arsenic, phosphorus, or silicon. And these other materials were indeed mixed with copper during the Bronze Age (arsenic was actually common there).

Lawrence Krauss vs Biden's woke science administrator

...and the National Academy of Sciences...

A picture from the article we discuss. You may click to have an idea about the woke people's discussions on Twitter.

Tom W. has sent me a link to this essay by cosmologist Lawrence Krauss (a noted atheist activist and one of the people who saw the light about the looming discovery of the cosmological constant before it was seen in the 1990s, among other things) in the Wall Street Journal:

The New Scientific Method: Identity Politics (the paywall is just partial)
While Krauss has looked like another left-wing scientist-activist for decades and the WSJ is a RINO daily, I think, this almost sounds like a sane person's or rightwinger's alarm. Krauss points out that much of the funding (\$7 billion) for physical sciences comes from the Department of Energy. He complains both about the Biden Administration and the National Academy of Sciences because they seem to be in the process of politicizing and ruining science – I would add, along the lines of the Aryan Physics in Nazi Germany and Lysenkoism in the Soviet Union. Unlike Krauss' insights about the cosmological constant, this observation didn't exactly come "in time"! ;-)

California plans to torture kids who are great in maths

First, The Rebel News, the most important Canadian independent news agency, was banned at PayPal with no stated legitimate reason. At least, they can withdraw the remaining funds. But they couldn't even use PayPal to buy food – they need to investigate whether maple leafs are edible, among other things.

The far left terrorists who are behind this terrorist act need to be caught and executed (The Rebel News plan a lawsuit but sadly, the death penalty was abolished in 1976 in Canada) and if people like co-founders of PayPal Musk and Thiel fail to do something against similar terror perpetrated by their corporate child, they need to spend the rest of their lives in jail, too. I am so unbelievably disappointed by all these men.

Meanwhile, mathematically gifted kids are the main enemy in California's government agencies.

CALIFORNIA UNVEILS NEW WOKE MATH PROGRAM, ENCOURAGING TEACHERS TO PUNISH GOOD STUDENTS BY HOLDING THEM BACK
A super-idiotic revolutionary manifesto that has hundreds of pages (maybe we are talking about this truly juicy anti-white racist 83-page rant, thanks, Bill, maybe there is another one) was released by the California Health Department and is apparently being embraced by the California's Department of Education (but the stuff hasn't been completely approved yet). Words are no longer enough, the authors claim. We must act and erase the inequality by holding back all kids who are better in mathematics than others. All instruction must proceed according to the weakest student in the class because the far left sick animals "reject ideas of natural gifts and talents". In that state and others, it's not only tolerated but fashionable to "reject" even the most obvious facts about the real world. According to the plan, the smart kids must be made unable to work on their mathematical talent, at least up to their 18th birthday. Wow.

100 marbles and a doubling, a puzzle

One hundred marbles numbered 1 through 100 are in a bowl. The marbles are drawn one at a time without replacement. How many marbles must be drawn to be sure that one of the selected numbers is exactly twice as large as another selected number?
I received this problem via WhatsApp. If someone has given a home office problem to her students and they're cheating, then I am sorry but this remote learning is guaranteed to lead to a similar cheating and it's not my fault (and I have fought against the Covid-19 hysteria, lockdowns, home offices, and shutdowns as much as I could). Moreover, you don't know whether my solution is right.

Divide the marbles (numbers 1-100) to the smallest classes in which the potential collision (of a number with its double) may occur. Each class contains all the numbers$\{ k\cdot 2^M, \quad M\in\ZZ \}$ for some $$k\in \ZZ$$, $$1\leq k\leq 100$$. So one of the classes is $$\{1,2,4,8,16,32,64\}$$, another class is $$\{3,6,12,24,48,96\}$$, and so on. If you want to pick a maximum number of marbles so that the "collision with a doubled value" doesn't occur, these classes may be treated independently.

Reorganizing a 4D S-matrix within a celestial CFT

For a couple of years, Andy Strominger and his so far lesser but not last collaborators have been immensely excited about the celestial sphere.

It's not hard to see why. As you can see, the celestial sphere (in the sky) is blue and has pretty stars in it.

Strominger et al. have studied the encoding of black hole information as seen on that sphere, scattering, hair, new conservation laws, and other related things. Note that if you imagine that we live in a 3+1-dimensional spacetime for a while, what we see at night (at one moment) is a two-sphere, $$S^2$$, of possible directions. Each point on this $$S^2$$ is actually a line in the 4D Minkowski space which goes to infinity. That's why there is no natural finite "length scale" defined on this $$S^2$$. However, you may measure angles. After all, this $$S^2$$ is conformally equivalent to a complex plane and the angle-preserving, conformal $$SL(2,\CC)$$ transformations of this plane (or sphere) are equivalent to the $$SO(3,1)$$ Lorentz group that transforms the Minkowski space.

As you must have heard, the Czech intelligence services have claimed that it was very likely that a 2014 ammo depot blast in Eastern Czechia (in Vrbětice) was caused by Russian agents – in fact, by the same Petrov and Bashirov who have also allegedly prepared novichok for Mr Skripal later, in 2018. The accusations have led to the expulsion of Russian diplomats from Prague and the reciprocal expulsion of Czech diplomats from Moscow, aside from related new hostilities between countries whose relationships were decent in recent years.

However, SeznamZpravy.cz (DirectoryNews.cz), a news server connected to Seznam.cz, a Google-killing Czech search engine, has published an incredible twist hours ago. Mr Janek Kroupa and Ms Kristina Ciroková are signed under the report. While I consider SeznamZpravy.cz to be one of the neo-Marxist cesspools of the Czech journalism (fortunately they are a minority here, but not a small minority), Janek Kroupa is a highly nontrivial investigative journalist. I am pretty sure that it is fair to count him among the top 5 active investigate journalists in Czechia. I remember his interview with the most relevant witness (from Pilsen) who testified that Mr Jiří Kajínek, Czech women's most beloved killer (who has managed to escape from many prisons), has indeed killed an entrepreneur and threatened some witnesses. Kroupa (along with Ms Sabina Slonková, a redhead) has also revealed amazing stories about the trip of PM's son Andrej Babiš Jr (who is at least officially psychiatrically handicapped) from Switzerland to Crimea. Although he is really standing on a wrong side of many political battles, Kroupa's purely professional ability to find the relevant witnesses and the data from them seems extraordinary to me.

Science that systematically produces progress only began in Galileo's time

Let me add a few words about the inability of the ancient Greeks and Romans to start the industrial revolution – a fact that is obvious but it is deliberately obfuscated by various retarded (in 2021) warriors against slavery.

These ancient civilizations and their thinkers-in-chief were really great and the seeds of many scientific disciplines were created by the ancient thinkers. I have surely often called their activity "science" a few times, too. However, one must understand that it wasn't a "full-blown science" that really works. The scientific method was introduced by Galileo Galilei (1564-1642).

The world is controlled by the cosmic manager and lawyer

Guest blog by Prof Dr Maria LePen-Sklo-Kaczynski

I am an ingenious intersectional lady. For my whole life, since I was 3 years old, I was working on a theory of everything. And I have just completed it. It seems necessary to quickly publish it because I've heard about some Italian competition that also claims to complete the theory.

In fact, mine isn't just a theory of everything. It is the grandmother of all theories of everything from which all other theories of everything gradually arise. The magic trick is the theories' friendly multicultural cooperation with the other theories and their complete equality. The individual theories are increasingly holistic and intersectional and their grandmother makes them ever more progressive.

Ancient Greeks couldn't have started the industrial revolution

A retarded warrior against slavery – which has been abolished for a long time, indeed – has demonstrated similar comrades' total absence of basic education, intelligence, and common sense. Under the blog post about Newton who benefited from colonialism, he denied the fact that every sensible person knows, namely that slavery (like many things that are mindlessly frowned upon by leftists today) has played an important role for the development of many civilizations, starting with ancient Greece and Rome and later the United States of America.

Plato, an ancient philosopher living in Athens, just returned from a 21st century barber.

Concerning the former, the ancient world, structures that were left wouldn't stand without slaves. For example, The Colosseum was built within a decade but up to 100 thousand slaves had to work on it! We just wouldn't have The Colosseum and many similar gems without slavery. Everyone who claims that slavery shouldn't have ever existed is the same kind of a savage as the ISIS savages who were demolishing the structures in the Middle East. Concerning the latter, the independence of the United States of America heavily depended on cotton, pretty much the most important U.S. export. That's why the South – and slaves that were needed for a sufficient amount of this production – has played a greater role for the very existence of the independent U.S. than the North. The South (with its slaveowners and everyone else) was being "exploited" by the North.

French Sixth Republic and the Confederate States of Europe

France is a global cradle of republicanism. Its republic has been updated a few times. Right now, the country is organized as the (semi-presidential) Fifth French Republic that was established by Charles De Gaulle in 1958. Days ago, 20 retired top generals, almost 100 other VIP officers, and 1,000 other army folks have signed

in his interactions with the Islamist separatism that is creating growing no-go zones ruled by medieval dogmas that are in a direct conflict with the French constitution. To allow this creeping transformation means to bring a civil war closer, the military elite warns, and if Macron fails to return the French nation and its secular constitutional principles to the top of the principles that apply across the official territory of France, the military folks promise a takeover of the country by the French military personnel who are claimed to support the generals.

The female minister of defense has showed her utter arrogance and cluelessness and she has both mocked and threatened the former and current heavyweights of the military. On the other hand, Marine Le Pen has endorsed the generals.

Isaac Newton benefited from colonialism

In recent years, neomarxist lies, distortions, and hateful emotions have been penetrating to places where they looked almost unimaginable just a decade ago, including the physics departments. The Daily Mail (and originally The Telegraph which has a paywall, however) brought us news from Sheffield University in the U.K. (which is arguably the country that is more contaminated by the neomarxist poison than any other country in the world):

Students could be told how Sir Isaac Newton 'benefited from colonialism' in curriculum overhaul being considered at Sheffield University
Leaked documents indicate that the university will try to introduce an "inclusive curriculum" of physics by demanding that the instructors include anti-white disclaimers. These disclaimers target Isaac Newton, probably the most ingenious thinker in the known human history, as well as other giants such as Newton's foe Gottfried von Leibniz, Pierre-Simon Laplace, and Paul Dirac.

Ivan Havel, 1938-2021

Ivan M. Havel died yesterday, on Sunday. He was found dead in the bathtub.

He was born on October 11th, 1938, two years after his older and more famous brother Václav Havel, in Czecho-Slovakia. This hyphenation is correct because on October 1st, 1938, following the Munich Treaty, our country got rearranged to the rather disgusting Second Republic of Czecho-Slovakia where various rats and Nazis (not only the Slovak fascists responsible for the capitalization of S) became powerful – much like their counterparts are getting powerful today (especially in the U.S. and Western Europe). The Second Republic lasted for 5+ months up to mid March 1939 when the peaceful Nazi occupation started the full-blown Protectorate of Bohemia and Moravia.

I knew him in person, unlike his brother Václav. In particular, roughly a decade ago, I was giving about three lectures (on 3 different years) after him at a Summer School of Young Philosophers near Olomouc (in the Church of Gradual Decontamination of Virgin Mary in Oak upon Morava, not sure whether my decontamination terminology is used by the U.S. Catholics LOL). In one of those cases, he was kind enough to lend me his laptop.
