The change of the significance level by 0.7 sigma doesn't justify any "big words"

Rajesh: the next, tenth season of TBBT may be the last one

Stops: CMS sees an excess over 2 sigma in their search for top squarks, see page 3, Figure 2, lower left. \(600\GeV\) stops may be "indicated" by that picture.

Adam Falkowski often acts as a reasonable (and educated) man. But I think that his title
CMS: Higgs to mu tau is going away
is a typical example of the insane exaggeration or distortion that I would expect from unethical journalistic hyenas, not from a particle physicist.

What's going on? Both ATLAS and CMS have shown some weak hints of a possible "flavor violation", namely the possible decay of the \(125\GeV\) Higgs boson to a strange lepton pair\[

h \to \mu^\pm \tau^\mp

\] Note that the muon and the tau are "similar" but so far, we've always created a muon-antimuon or tau-antitau pair. The individual lepton numbers \(L_e, L_\mu,L_\tau\) for the generations have been preserved. And the Standard Model makes such a situation natural (although one may predict some really tiny flavor-violating processes even in the Standard Model).

Because the muon of one sign is combined with the tau with another sign – with a particle from a different generation of leptons – the process above, if possible, would be one of the so-called (and so far unseen) flavor-violating processes.

Socialists are murdering the economy of Venezuela right now

Venezuela is becoming the latest role model for nations that are incapable of curing themselves from leftism and from the leftists before it's too late.

The country is sitting on a huge amount of oil. Petroleum accounts for more than 50% of the GDP. So you may imagine that the low prices near $25 a barrel earlier in this year didn't help. But the prices are back around $50 and even when they were closer to $100 two years ago, things began to look really bad for Venezuela.

Hugo Chávez, the Bolshevik dictator, took over in 1999 and was dragging his country towards a socialist "paradise" up to his death in 2013. Nicolás Maduro, a Chávez yes-man, became the successor. He has less charisma than Chávez used to boast – but his politics is equally socialist.

EU: all publicly funded science papers free since 2020?

Some EU authorities have presented an ambitious plan. The Competitiveness Council and the Dutch EU presidency were involved. (On July 1st, Slovakia will take over the EU presidency.)

In four years, all scientific papers resulting from publicly funded research should be available to everyone for free.

German bishops, ministers want mandatory Islam at schools

The Czech public is absolutely stunned by a development in Germany – which some global media already described yesterday.

Top center-right server just told us that Germany's highest evangelical bishop Heinrich Bedford-Strohm, a Lutheran, and the minister of interior, Thomas de Maizière, support a new plan to make the classes of Islam mandatory at all schools in all German lands. (The lands of East Germany don't even teach Christianity at state schools right now.) Islamic organizations would be directly responsible for the education.


I happen to agree with all the most upvoted comments so here they are.

Learning of information, not an interaction, induces the collapse

The dishonest Bohmist crackpot filth continued to be everywhere – on the Physics Stack Exchange, the Quanta Magazine, and elsewhere – so it was pleasant to see a new, one-week-old YouTube video by Inspiring Philosophy about quantum mechanics, a video I may fully endorse.

Last time, in a discussion with him on this blog, I was annoyed by his view that philosophers such as Kant or Hegel or their ideas should "stand above" the physics research which I consider totally ludicrous because physics must use its own philosophy and persistently upgrade it as the evidence arrives and is evaluated in better ways. And the old guys' philosophy is clearly outdated enough to be unusable in the context of modern physics.

I have also disliked some basic technical misunderstanding – I forgot what it was – but all these things are forgotten by now.

Do male rats using cell phones get healthy tumors?

NBC News and others just informed about partial results of some new $25 million U.S. government of health impact of cell phones. The full results should be out in 2017.

They claim that rats get brain and heart cancer out of the cell phone radiation. But only the male rats. And those tumors are great because they increase the rats' life expectancy! ;-)

Czech think tank's meta-analysis: 44% of European Muslims are fundamentalists

The Prague Monitor has informed the readers about a survey published by the Czech "European Values" think tank,

Views of 44% of Europe Muslims are fundamentalist, Czech study shows
There have been various attempts to claim that terrorism and anti-Western terrorism is confined to a tiny subgroup of the Muslims. Needless to say, the percentage of Muslims who have "achieved" something as spectacular as the 9/11 attacks is tiny. On the other hand, the percentage of Muslims who agree with basically all important religious, social, and political opinions of the terrorists is large – comparable to 50%.

CLOUD@CERN: global warming may have been due to decreasing aroma from trees

Just a short report plus a collection of links (thanks to Steve from CERN).

CLOUD, the experiment that measures the birth of clouds at CERN, has released new papers:

Nature: Ion-induced nucleation of pure biogenic particles

Science: New particle formation in the free troposphere: A question of chemistry and timing

AP (a popular/politicized distortion): New Cloud Formation Discovery May Lessen Warming Forecast
CLOUD has done lots of measurements of the processes that are needed to create clouds which, as many kids have noticed, usually cool down the weather.

The experiment has been taking place at CERN because the cosmic rays (emulated by the CERN's sources of beams) are important for the creation of the cloud (condensation) nuclei. Even in the new papers, cosmic rays are found to increase the nucleation rate by 1-2 orders of magnitude.

Recall that the Sun's activity may influence the cosmic ray flux, and therefore its variations may be responsible for "climate change". Svensmark's theory generally argues that a stronger solar activity means a more perfect shielding of the cosmic rays, therefore less cloudiness, and therefore warmer weather.

Higgs to mu-tau decays would encourage \(B-L\) SSM

While Egyptian airplanes keep on collapsing (President el-Sisi's foes have decorated the same aircraft with graffiti "we will bring this aircraft down" some two years ago!) and Erdogan keeps on blackmailing Europe (and proving the cluelessness of the politicians who wanted or want to promote Turkey into a key solver of Europe's problems), a new Turkish-Egyptian hep-ph paper looks unexpectedly sexy:

Large \(BR(h \to \tau \mu)\) in Supersymmetric Models
Hammad, Khalil, and Un analyze how compatible the simple enough supersymmetric models are with a possibly emerging result of the LHC analyses – namely the decay of the Higgs to a flavor-violating pair\[

h\to\mu^\pm \tau^\mp

\] which seems to appear in roughly a 2-sigma excessive number of events both at ATLAS and CMS and the suggested branching ratio is around 1%.

I don't feel frightened not knowing things

The most recent exchange about the extraterrestrial life made me think of this monologue of Richard Feynman,

especially its last minute. Why? Because it seems to me that some people are so frightened not knowing things that they prefer quickly chosen wrong answers over the admission that they're ignorant or uncertain.

In these sentences (taken from The Pleasure of Finding Things Out, BBC/NOVA, 1981), Feynman said that some people are searching for answers to deep questions that science can't answer or basically labels as unphysical, so they may get disappointed and turn to religion and other mystical world views instead.

He also describes the Copernican principle – the existing religions seem too provincial, too connecting the fundamental entities of the Creation with our particular stinky pond here on Earth, our DNA etc. These links seem totally out of proportion.

An interview with Klára Samková has published an interview with Klára Samková.

Samková for EuroNews: Ambassador of Turkey has behaved as an old woman. Muslims are expecting that their ideology will be tolerated.

An interview: It is quite appropriate to compare Islam with totalitarian ideologies and the Turkish ambassador has escaped the hall as a pubertal boy, attorney Klára Samková says in an interview for She has ignited passions by its speech directed against Islam. Does she expect some further repercussions of the story? And why did she voluntarily help to Muslims years ago?

German prosecutors free all ecoterrorists from Schwarze Pumpe

Recent immigrants from the Muslim world are not the only group that seems to stand above the law in Germany. During the weekend a week ago, there was a violent rally inside a power plant and a brown coal mine in East Germany, close to the Czech border. The events at the Schwarze Pumpe looked like this:

Some more videos

Both businesses had to be pretty much closed for the weekend. The fences were destroyed and the police action was costly, too. You may imagine that it would be very hard for these mostly worthless terrorists to pay for all the damages they have caused.

Topology, geometry in QG admit no operators, measurement

Santa Barbara's David Berenstein and his student Alexandra Miller published a paper

Topology and geometry cannot be measured by an operator measurement in quantum gravity
which is nice because they have used the LLM limit of Maldacena's AdS/CFT correspondence to rediscover something that the TRF readers know from about 10 blog posts and that has been refined into a more controllable paper form by Papadodimas and Raju. There can't be any linear operators in a theory of quantum gravity whose eigenvalues would correspond to the topological invariants of the space. I think that the adjective "state-independent" should be added to the sentence to make it really true – Berenstein and Miller implicitly talk about state-independent operators when they talk about operators.

LLM refers to Lin, Lunin, Maldacena – it's the bubbling AdS space – and this aspect of the Berenstein-Miller paper is new. If you click at the hyperlink, you will be brought to a January 2005 blog post about LLM. The date should assure you that TRF is quite an ancient source of information about physics.

Messaging the ETs: science or (dangerous) religion?

There have been dozens of blog posts about the extraterrestrial life. I generally believe that the widespread opinion that the life is almost everywhere is unjustifiable, directly clashing with certain emerging data, and the life on our planet may very well be very rare if not unique. I've agreed with Michael Crichton's criticism of Drake's equation, among other things.

Geological data suggest that the life began shortly after the Earth was created. But this doesn't prove that it must be likely for life to emerge. Instead, one may argue that life came from outside the Earth – panspermia – and depended on the satisfaction of many conditions that required increasingly concentrated and increasingly advanced seeds of life.

Almost equivalently, the evolution of the early life forms may have depended on many deadlines. Some amino acids or other things may have been much more likely to be created when the Earth was new, hot, and chaotic, and the probability may have been dramatically decreasing ever since. The required stages of life had to be created during the early stages and they were – but they didn't have to. This picture is compatible both with a tiny concentration of life in the Universe and with its early appearance on Earth.

But that's not what I want to talk about here.

Benjamin Kuras: the West's suicide

Almost all the speakers at the event "Should we be afraid of Islam?" organized in the halls of the Czech Parliament four days ago were giving the answer "No, they are or we are friends". Klára Samková gave the answer No, we should fight which has become well-known, at least to the readers of Breitbart.

The only other speech that was unequivocally arguing against the Islamic immigration (albeit a bit less loudly than Samková) was one by Benjamin Kuras, a British writer, playright, and translator who was born as Miloslav Kuraš in the Protectorate of Bohemia and Moravia in 1944 (not easy for an ethnic Jew!), has practiced Judaism since 1974, six years after he emigrated to the U.K. in 1968. Here is my translation of his speech. (It's likely that he has an English version somewhere but let me practice.)

Klára Samková's talk: Should we be afraid of Islam?

Update: When you become familiar with this talk, you may also read the similar speech by Benjamin Kuras at the same event (which is slightly more peaceful than the speech below). Check also Czech ex-president Klaus' speech in Tel Aviv 3 days ago about the supply-and-demand side of mass migration and why the "entitlement behind it" is a big misinterpretation of human rights.

A translation to Portuguese here.

Update: See a newer interview with Samková
When I studied in detail, I found the well-known attorney's lecture for the ambassadors of the Muslim countries and other guests in the Czech Parliament much better than I expected (even though "stronger" than the type of language that I would naturally use), so here's a translation. There are many references to things like physics, some of them a bit silly, but they make the text more appropriate for this blog, anyway.

Dear guests, [May 18th, 2016]

thank you for the invitation and the opportunity to give a speech. Today's conference is supposed to help to answer the question whether we should be afraid of Islam. My answer to the question is straightforward: we should definitely not be afraid of Islam. We should deal with it in the same way in which the European civilization has dealt with all totalitarian and inhuman regimes which it had to face during more than 2,000 years of its history. In particular, we should fight with Islam, beat it, and prevent its proliferation once and for all, just like in the case of previous monstrous ideologies, declare the very existence of Islam as a criminal act that contradicts the human naturalness, freedom, and especially the human dignity.

Airlines should sell Muslim-free flights

After a 3-hour-long flight from Paris and shortly before it was supposed to land in Cairo, EgyptAir's MS804 disappeared from the radar and some two hours later (or maybe much earlier), it crashed to the Mediterranean Sea, somewhere between Egypt and Crete, and the wreckage was just found near Karpathos, a Greek island. In a few hours, this finding will be declared invalid but tomorrow, the Egyptian army will find the wreckage 290 km north of Alexandria. My condolences to the friends and relatives of the 56 passengers and 10 crew members.

The cause is unknown but it's generally believed that terror is a more likely explanation than a technical problem. Seven hours ago, Donald Trump tweeted:

Looks like yet another terrorist attack. Airplane departed from Paris. When will we get tough, smart and vigilant? Great hate and sickness!
A great question.

Particles are vibrations

The music analogy is much more accurate than most people want to believe

Tetragraviton is a postdoc at the Perimeter Institute who has written several papers on multiloop amplitudes in gauge theory. Even though none of these papers depends on string theory in any tangible way, I've thought that he's a guy close enough to string theory who could potentially work on it which is why I was surprised by his blog post a week ago,

Particles Aren’t Vibrations (at Least, Not the Ones You Think)
which indicates that I was wrong. The first sentence tells you what kind of popularizers are supposed to be a target:
You’ve probably heard this story before, likely from Brian Greene.
I was imagining that there was something subtle. People may dislike the overabundant comments about "music and string theory" etc. But I didn't find anything too subtle in the blog post. While there's always some room for interpretations what a somewhat vague sentence addressed to the laymen could have meant, I think it's right to conclude that Tetragraviton is just flatly wrong.

Slowly for Peter Shor: Page 1 of Dirac

Most of the people who want to argue with me about quantum mechanics are marginal figures such as the psychopath named John Duffield who has picked Paul Dirac as the ultimate man who was "hampered because he didn't have an understanding of the electron".

Imagine, among tens of billions of humans who have ever lived or live on the Earth, Paul Dirac has clearly introduced much more clarity to our understanding of the electron than anyone else, but this Gentleman is willing to pick Paul Dirac as the "guy who was hampered by misunderstanding the electron". It often looks like these people are competing to write the most absurd or psychopathic sentence anyone can write down.

So it was refreshing to have some disagreement with MIT's Peter Shor again, a guy who is well-known because of a quantum algorithm. I think he's an expert on many related things and most (?) of his comments about foundations of QM are just fine. But like the postmodern feminist philosophers, he seems to believe that the theorems in mathematics and physics only apply when certain sociological criteria are obeyed.

Ivana Trump co-invented, delayed, advises Trump presidency

A month ago, ABC News discussed the Czech factor behind the Donald's presidency, his first wife Ivana Trump or Ivana Zelníčková-Winklmayrová-Trumpová-Mazzucchelliová-Rubicondiová, if you wish, and I have generously omitted Syrovatková. ;-)

Trump is often presented as an ultimate egotist or materialist or serial divorcer. But he's really an idealist faithful saint relatively to his first wife. He must have loved her but their marriage didn't last indefinitely.

Weak gravity conjecture linked to many fields of maths, physics: an essay

Ben Heidenreich, Matthew Reece, and Tom Rudelius (Harvard) have won the 5th place in the 2016 Gravity Research Foundation Essay Contest (I will avoid the general rating of this kind of essay contests):

Axion Experiments to Algebraic Geometry: Testing Quantum Gravity via the Weak Gravity Conjecture
They discuss a refinement of our conjecture that for any type of a "charge" similar to electromagnetism, there must always exist sources for which the non-gravitational force donalds the gravitational one.

The essay shows that the inequality has implications for inflation (naively excluding a long enough inflation and maybe forcing one to talk about specific types of inflation), for AdS/CFT (charged operators with low enough dimensions should exist), and for pure mathematics (because the inequality should hold for compactifications on complicated enough manifolds, and such an inequality therefore sometimes turns into a nontrivial geometric theorem about those).

Anti-quantum zealots have deduced exactly the opposite conclusion again

I am overbohmized – the Bohmians recently exploded like the mosquitoes on a warm and wet summer evening – but this is a story I can't omit. The Quanta Magazine published an article by Dan Falk

New Support for Alternative Quantum View

An experiment claims to have invalidated a decades-old criticism against pilot-wave theory, an alternative formulation of quantum mechanics that avoids the most baffling features of the subatomic universe.
The title and the subtitle are just 100% lies. They should have said:
Another nail in the coffin of an anti-quantum hypothesis

An experiment has verified a decades-old criticism against pilot wave theory, a superfluous ideological superstructure meant to deny the most important insights of the quantum revolution.
Can you spot the difference? I find it amazing how these people don't just "subtly modify" and "distort" the message. They just lie into your eyes. They're eager to turn things by 180 degrees and tell you the exact opposite of the results. These individuals lack the basic morality.
