BBC, media suddenly join TRF: Craig Wright created the Bitcoin

In December 2015, you could read my comments why

I would bet: Sydney climate skeptic is the father of the Bitcoin
At that time, lots of tech media mentioned the emerging evidence that Craig Steven Wright (*1970) created the world's most famous cryptocurrency but almost all of them were mostly skeptical and those who were not skeptical were sort of dismissed.



Five months ago, Wright wasn't loudly boasting – and he wasn't even explicitly admitting – that he was the father of the Bitcoin. However, he didn't say "No", either, and the dominant theme in the newspaper articles was that "he created some bogus evidence that would make others think that he was the creator of the Bitcoin".

I just found such a theory analogous to the conspiracy theories about the moonlanding staged by Hollywood in Nevada.

Much like it is easier and more straightforward to actually build and send some rockets to the Moon (the laws of physics make it clear that it may be done and it isn't infinitely different from the airplanes) than to create a network that convinces hundreds and then billions of people that they're taking a part in a great engineering event that isn't real, it just seems much more straightforward to actually write the paper and the programs; than to create a fake life consistent with someone's being the father of the Bitcoin.

Claude Shannon at 100: who are his living peers?

Claude Shannon was born exactly 100 years ago, on April 30th, 1916. After I quick read the Wikipedia page, it seems to me that he is rightfully considered a father of the digital age and one of the greatest 20th century engineers whose work was important enough to impact science, too.

He died in 2001.

(Interestingly enough, an important "she" from my undergraduate years was born exactly 40 years ago, i.e. 60 years after Shannon. Congratulations. In Czechia, April 30th is the day of burning of the witches, see some videos, although they're mostly less real than those in Salem, MA. For a May 1st romantic event, read Mácha's poem "Máj".)

Shannon was born in Michigan. His father was a self-made businessman (at some district level, I could describe my dad in the same way) and his mother was a teacher.

Bohmian mechanics is incompatible with loop corrections

...meaning the Feynman diagrams...

Florin Moldoveanu wrote his review of Hardy's paradox. Like the GHZM experiment, it's another "mostly qubits-based" quantum thought (or real) experiments that behaves in a way predicted by any local realist theory to be impossible.

Florin's presentation is a bit shallower than my blog post on Hardy's paradox or his treatment of the GHZM case but I am willing to believe that he understands how it works.

The original paper by Lucien Hardy included the annihilation of an electron and a positron into two photons; and Jean Bricmont, a pro-Bohmian ideologue, recently published his book attacking the foundations of quantum mechanics. So I think it could be a good moment to write a blog post dedicated to this specific topic of "Bohmian mechanics vs effects of QFT", something I have wanted to do for some time.

A new conservation law in GR discovered thanks to ER=EPR

An attack turned off the LHC: a terrorist (picture) made it necessary to stop the LHC. Due to a damage of the transformer, there won't be any beam up to next Friday. I still think that weasel words create many more problems than weasels.
I primarily view the ER-EPR correspondence (the equivalence of the non-traversable wormholes and the quantum entanglement) as an important conceptual finding that is directing people's research of the most esoteric, most quantum aspects of quantum gravity – the cutting-edge questions in this most fundamental part of theoretical physics. We learn about some new constraints in the rules that govern the Hilbert spaces in quantum gravity.

However, three Caltech authors, Remmen+Bao+Pollack, just showed a rather cool example of the wisdom that may also flow in the opposite direction:
Entanglement Conservation, ER=EPR, and a New Classical Area Theorem for Wormholes
Because the entanglement is the same thing as the wormhole and there exist some facts we may derive about the entanglement in general, there could be facts that we may derive about the pure simple classical Einstein's general theory of relativity, too.

This result is so pleasing that I immediately forgave these folks their collaboration with Sean Carroll in the past. Whoever co-authors a paper such as this one earns enough scientific capital to write three nutty papers e.g. about the Boltzmann Brains.

Consensus and concordance models

Syed Ali of Pakistan asked the following question on Stack Exchange:

What is the difference between the Big Bang Model and the Λ-CDM Model?

If I'm going to write about "The Consensus Model of Cosmology" should I include Big Bang Model or should I go with just the ΛCDM Model?
Well, it's subtle. On that page, I explained the difference between the ΛCDM model and the more general term, the big bang theory.

The former is more detailed than the latter; it also says that there's a big positive cosmological constant (Λ in ΛCDM) and cold dark matter (CDM) in the Universe. Cosmologists are generally certain about the big bang and almost all of them think that ΛCDM is basically correct as well. But there are various uncertainties, various degrees of certainty about different questions, and "consensus" is just an inappropriate word to talk about science.



Even if we added the cosmic inflation, the majority of active cosmologists would probably say "Yes". But no specific "subtype" of inflation would already get over 50% of all cosmologists, I think. And what is the dark matter composed of? WIMP would be the winner but whether it would score more than 50% is debatable. It's been reported that the younger generation of cosmologists is much more willing to abandon WIMP theories. This particular evolution seems reasonably defensible to me, unlike some others.

Anti-quantum zealots don't even get that QM is a physical theory

Their peabrains are also incapable of understanding the word "No"

Maybe it's just because I have increased the frequency with which I write about the foundations of quantum mechanics and people send me various stuff. But the amount of anti-quantum misconceptions that I have been exposed to in recent weeks was higher than ever before.

At the end, almost all if not all of these people just aren't willing or able to even consider the possibility that the assumptions of classical physics are wrong. It must sound surprising to an open-minded student who hasn't faced any serious obstacles when he was learning quantum mechanics. But when you actually interact with these anti-quantum zealots and you see how they react to some extremely simple, rock-solid explanations of yours, you simply have to conclude that their IQ is probably below 70. The degree of stupidity they are willing to promote in order to defend the indefensible is shocking.

Czech nuclear watchdog: a trip to Chernobyl is safe for you

A more exciting tourist destination than most others

Yesterday, on the 30th anniversary of the Chernobyl accident, the chairwoman of the Czech State Office for Nuclear Safety Dr Dana Drábová gave an interview for the left-wing daily Právo and the news server Novinky.cz.

A trip to the forbidden zone in Chernobyl? Why not, it won't hurt, claims nuclear physicist Drábová

The areas contaminated after the accident at the Chernobyl nuclear plant have turned into founts of wisdom, claims Dana Drábová in the Tuesday's interview for the Právo daily. She is the chairwoman of the State Bureau for Nuclear Safety. According to her words, an educational sightseeing trip to the Chernobyl zone won't harm anyone because the guides know which places are safe to visit.

Research in Prague quantifies dishonesty of literature on climate sensitivity

The power of meta-analyses in measuring the density of scammers in the climate alarmist industry

Although one or two climate blogs have already noticed the clever paper in August 2015 when it was published, most of us were unaware of it. That included myself – even though the paper was published by authors at my Alma Mater, Charles University in Prague (founded 1348). They're from the Faculty of Social Sciences (FSV UK) – a much more quantitative department than the name indicates. A classmate of mine (whom I spent 6 years with behind the same school desk) completed FSV UK and then went to the London School of Economics before he became a director at the Patria Finance for some time. ;-)



Figure 3 from the paper makes the bias obvious.

Sadly, the paper published in Energy & Environment remained almost unknown for almost a year. Fortunately, Richard Tol sent the paper to Willie Soon and he sent it to me today. The 2015 paper is freely available on a Czech website:

Publication Bias in Measuring Anthropogenic Climate Change (also: a PowerPoint talk)
The authors are Dr Dominika Rečková (CZ) and Dr Zuzana Iršová (SK). Note that in Czech and Slovak, the -ová suffix indicates that they're female. That doesn't change the fact that their methodology is very clever.

When anti-CO2, junk food pseudosciences team up

Among other things, a Czech-Swedish man showed me an article in the April 9th issue of Nude Socialist

Reaping what we sow (pages 18-19)
written by Irakli Loladze (Google Scholar), a professor of junk food science at a college I've never heard of. He told us that he wanted to get lots of money and Barack Obama (whose relationship to science is accurately described by his being a painful footnote in the curved constitutional space) finally gave Loladze some big bucks for the excellent "research" that Loladze already wanted to do in 2002.



What is the result of the research? It's a simple combination of the pseudosciences about the "evil junk food" and about the "evil CO2". It says that CO2 turns out food into junk food. I kid you not. The one-page article in Nude Socialist contains basically nothing beyond the previous sentence written in the bold face.

Omnipresent in-fighting weakens right-wingers

Trump vs Koch, Farage vs Le Pen, Klaus vs Mach, Dawn vs Bloc Against Islam...

In recent 24 hours, I read about an unusual excess of the tensions between various pairs of right-wing politicians (and a businessman). It seems that these conflicts can be found everywhere on the right side of the political spectrum. Some frustration coming from the politicians' perceived failure to become important may be partially blamed for the trend.

First, Charles Koch prefers Hillary Clinton over Donald Trump and Ted Cruz. He says some good things about the economic policies of Bill Clinton – I obviously sometimes say similar things – but he also adds that it's unacceptable for the GOP candidates to vigorously defend America against the radical Islam (by Muslim travel bans and carpet bombing of Daesh, respectively).

5,000 cernettes with \(750\GeV\) may be found in the LHC trash bins each year

The excess of the diphoton events whose invariant mass is apparently \(750\GeV\), the decay products of the hypothetical new "cernette" particles, is arguably the most convincing or most tantalizing existing experimental hint of the Beyond the Standard Model physics at the LHC right now. I estimate the probability that a new particle (or new particles) exists in that region to be 50%.

Nude Socialist just posted an interesting story

Hacking the LHC to sift trash could help find a mystery particle
about a possibly clever idea to dramatically increase the sensitivity of the LHC to the "cernettes" that was reported in a fresh hep-ex preprint
Turning the LHC Ring into a New Physics Search Machine
by 4 physicists from Iowa, Helsinki, and CERN that include Risto Orava. Orava is a cute region in the Northwestern Slovak countryside (pix) where Elon Musk just built Tesla Orava, a company producing some incredibly hot futuristic high-tech products including the Color Oravan TV that I can already/still offer you. Tesla Czechoslovakia just succeeded in selling 100,000 new vinyl record players to Japan. (Everyone laughs now.) The Japanese bought them as carousels for puppet shows.

Can a biologist deepen the foundations of quantum mechanics?

In this case, it doesn't look so to me.

I have finally found fifteen minus to devour "biologist of perception" Donald Hoffman's thoughts in the Quanta Magazine,

The Evolutionary Argument Against Reality
It seems to me that he just says that the reality doesn't exist and natural selection punishes those who see the truth or the reality. Do you see anything more well-defined, a more convincing argument, or an entirely new additional idea in the article that isn't summarized by the previous sentence?

At several places, he suggests that he defends this "reality doesn't exist" viewpoint because he takes quantum mechanics seriously and much of this philosophy probably sounds similar to my comments about quantum mechanics to many people's ears. The only problem is that I think that the quantum beef is either entirely missing or seriously distorted in Hoffman's remarks. Instead, what I see is some superficial, partially wrong, and partially trivial philosophizing about the world that many people completely misunderstanding everything about quantum mechanics like to say, too.

If you expect the Quanta Magazine article to tell you something quantitative about qualia – how perceptions are linked to the apparatus of quantum mechanics – you're bound to be disappointed.

175 nations signed, Paris climate insanity hasn't come to force yet

Era of consumption without worries is just getting started

Vladimir Lenin would celebrate a birthday yesterday so a couple of his true heirs – who want to cripple the world economy for much of the 21st century, much like their guru did 100 years earlier – gathered in New York to sign the insane Paris climate treaty.

It's a treaty in which the green activists in every nation invent an arbitrary five-year plan and they help their comrades in other countries to enforce this nation-specific anti-industrial terror on everyone else. They schedule a new convention each five years where their conspiracy is supposed to be updated. Whether this setup without any universal predetermined commitments may actually harm anyone is still debated. But the increase of the number of dirty parasites in the climate bureaucracy across the world and of the deceitful propaganda that these parasites need for their survival will certainly be genuine.

Czechia where almost everyone considers this deal to be just another big theft of the public money had the decency to send just a third-rate politician, the environment minister Richard Sparrow, to sign the deal in New York.

Brexit: Boris vs Barack. Will Obama join the EU?

The full text isn't known yet but it's been leaked that Obama will try to intervene into the British June 23rd referendum about the kingdom's departure from the European Union. (The Daily Telegraph honored Obama by offering him some room on the prestigious enough Page 20 today.)

Barack Obama will claim that Britain is a weak loser who doesn't have a chance to survive for a week away from Angela Merkel's and Jean-Claude Juncker's breasts. It's important for the strength of Britain to shut up and become an obedient servant of the bureaucracy in Brussels. Without the leadership of Merkel and others, Britain may degrade into a banana constitutional monarchy led by monarchs who even demanded exporters of tea to pay their taxes back in 1776. On the contrary, the permanent residence under Angela's skirt will make Britain much stronger, Obama argues.



Boris Johnson is the popular conservative mayor of London who happens to lead the "Out" camp of the Brexit referendum and, like 60% of Britons, he may have some issues with this meddling by Obama. In The Sun, he wrote an essay

Boris Johnson: UK and America can be better friends than ever Mr Obama... if we LEAVE the EU
He starts by some known data indicating that one of the first decisions of Obama in the White House was to remove the statue of Winston Churchill from the Oval Office – a statue that had spent a decade over there. It was silently returned to the U.K. embassy in DC on Day One. Chances are that Obama is a fanatical anti-imperialist and his partly Kenyan ancestry makes it even more likely.

Churchill was a great warrior for the strength of the British Empire – who not only helped to save the democratic world (and restore countries like Czechoslovakia: Churchill was the first major politician who left the old, 1938 European Union codified by the Munich Treaty) but who also sent some troops against some rebels in Kenya – so the Obama-Churchill chemistry didn't work too well.

Lawyer John Dixon bastardizes SUSY in two new papers

CERN: CMS releases the open data from 2.5/fb of 2011 collisions. I hope that you have 100 spare TB on your hard disks. ;-) Also, Christopher Nolan's brain melted 45 minutes after he began to talk to Kip Thorne, Time Magazine reported while praising Thorne's contribution to LIGO. Let me emphasize that Nolan's brain meltdown wasn't due to any global warming.

Two of the new hep-th papers today were written by John Dixon who offers Gmail as his affiliation (well, so would I right now, but many more people would know who I am):

Canonical Transformations can Dramatically Simplify Supersymmetry

Squarks and Sleptons are not needed for the SSM. They can be, and they should be, transformed away
While the titles are longer than they should be, they're pretty bold and simple claims. You can – and you should – completely erase all scalar partners of known fermions in supersymmetric theories. And that's desirable because no squarks and sleptons have been discovered yet. Well, there is a slight problem: These claims are self-evident rubbish.

If SUSY can be talked about at all, the operators \(Q_\alpha\) with a spinor index have to exist and no one can prevent you from asking what is \(Q\ket{\mu}\) where \(\ket\mu\) is a state with one muon, for example. You simply have to get a bosonic result. The result of the action of some SUSY generators has to be nonzero because the anticommutator of \(Q\)'s contains the momentum which is nonzero. So the action has to be a state with one bosonic particle with the same momentum, perhaps dressed into some stuff related to the SUSY-breaking sector, or this state may be in a different superselection sector (but these issues have to go away if SUSY is restored, e.g. at high energies).

So if the action of all these supercharges were zero, the action of the momentum on \(\ket\mu\) would have to vanish as well – but it clearly doesn't.

Czechia considers its own space agency

According to Space News, Czech deputy prime minister Pavel Bělobrádek (Whitebearded Paul, Christian Democrats, the smallest coalition party – here is why the party isn't larger, those 16% thought that they were asked about Godly Karel Gott) impressed his hosts at the Kennedy Space Center by an excellent idea almost no one in our homeland has heard yet: Czechia should establish its own space research center. At €15 million per year, Czechia's contributions to ESA belong among 3 post-communist countries' funds above €5 million.



Czechia was the third country to land humans at another planet. Note that in late 1992, they used the identical flag to the Polish one – it was believed that we wouldn't be able to steal the blue Slovak wedge and keep the Czechoslovak flag. These astronauts were caught by UFOyaga (just when Ms Tereshkova was being grilled) who wanted to devour them for her dinner but thanks to the Biostar from the U.S. spaceship, two of the Czech astronauts were able to escape and return to the Earth.

I am not sure how important and healthy our space program is right now. But there's some tradition to build upon, of course.

Harvard worships its radical, 1930s-style anti-Semites

First, a lighter story. After a century, America will be placing a woman on a banknote ($20) again. By inspiring a currently successful Broadway musical, Alexander Hamilton finally managed to save his life on the $10 bill. About eight other women (!) including my great grandmother Lucretia Motl will be squeezed to various places of new banknotes. The new banknotes will be prepared for 14 years and appear in 2030 if not later. That's embarrassing – Czechia and Slovakia had new banknotes within months after the dissolution of Czechoslovakia.

She was born as a slave, escaped, and helped others to escape. She changed her name later and I have forgotten both names. Sorry, I have no plans to memorize either name.

Her escape maneuvers and liberation were "good things" but they were mostly good for her and several people similar to hers. What she did may be viewed as her unsurprising care for her own interests. I just don't think it's right to say that those deeds were great acts for the United States of America or the mankind. For such reasons, I consider this replacement of Andrew Jackson to be a political kitsch of a sort or, as Donald Trump unsurprisingly said after I wrote the previous part of the sentence, it is pure political correctness. (Trump would place the "fantastic" woman on a bill no one uses.)

I am confident that most Americans have the same feeling but they're not even allowed to safely make this point because they're no longer in charge of their country and they have lost much of their freedom.
