Nature is subtle

Caltech has created their new Walter Burke Institute for Theoretical Physics. It's named after Walter Burke – but it is neither the actor nor the purser nor the hurler, it's Walter Burke the trustee so no one seems to give a damn about him.

Walter Burke, the actor

That's why John Preskill's speech focused on a different topic, namely his three principles of creating the environment for good physics.

Assyrian history destroyed

Many events are taking place every day and many events make me – and many of you – upset. But what made me extremely angry today was this ISIS video:

To skip the babbling by the apparatchik-bigot and to get to the drastic "action", jump to 2:40.

The animals have penetrated into Mosul, Northern Iraq, and they chose the local Nineveh Museum as their target. The museum contains lots of priceless (or at least multi-billion) statues from the neo-Assyrian empire. Well, it did contain it – up to yesterday.

Black hole microstates from gluing an exterior with its delayed twin

...and a proof of state-dependence of interior field operators...

Kyriakos Papadodimas (CERN) and Suvrat Raju (Tata) have released a five-page paper that is full of hot ambitious ideas as well as cool, almost rock-solid arguments about the "holographic code" describing the black hole interior:

Local Operators in the Eternal Black Hole
They work with the eternal Schwarzschild black hole in the \(AdS_{d+1}\) space. They describe it using the tortoise coordinate, one that I and Andy Neitzke learned to love when we studied the quasinormal modes. This coordinate makes the \(rt\)-plane look "conformal" and some world sheet methods may therefore become applicable; I would like to comment on this point of mine in more detail later.

At any rate, the eternal \(AdS\) black hole may be holographically described using two conformal field theories, \(CFT\), and an eternal black hole state is a maximally entangled state\[

\ket{\Psi} = \frac{1}{\sqrt{Z(\beta)}} \sum_E \exp(-\beta E / 2) \ket{E,E}

\] The first thing they appreciate is that one may evolve this state in time, by a Hamiltonian (i.e. one may wait), to obtain many inequivalent states \(\ket{\Psi_T}\) that seem to have indistinguishable local physics, however:\[

\ket{\Psi_T} = e^{iH_L T} \ket\Psi = e^{i H_R T} \ket \Psi

\] One either asks the object to "wait" for time \(T\) in the left \(CFT\) only; or in the right \(CFT\) only. In both cases, one gets the same result but the result depends on \(T\) nontrivially.

Ismail El Gizouli, new IPCC boss

Rajendra Pachauri has been the head of the International Panel for Climate Change for many years, having turned into a cell of organized crime.

This railway engineer and porn writer has had uncountable conflicts of interests and numerous conflicts with the law in the past but he was forced to resign because of a relative detail: his colleague who boasted voluptous heaving breasts in New Delhi sued him because she didn't like the way in which the love guru raped her. Well, it was probably her mistake, too. Everyone must have known what a dirty pr*ck this guy is, so a decent woman would keep the distance at least one mile from him.

He was replaced by Ismail El Gizouli. This vice-chairman representing Africa is famous for this December 2013 YouTube video hit. It seems to be the only publicly available web page about this Gentleman and when I was embedding it into this blog post, it had 8 views (and 2 of them counted the electronic devices of your humble correspondent). Quite a rock star!

Giuliani vs Obama 2015

Almost eight years ago, it looked like Rudy Giuliani and Barack Obama could have been going to compete for the White House.

Let's go, Obama girls.

Finally, America's mayor didn't make it through the primaries. You know, your humble correspondent probably isn't the most canonical guy who would have picked Giuliani but I would find him highly natural in the office, anyway. He's still a symbol of the mainstream America's leader who has everything that seemed necessary in those old years when I couldn't think about a single major complaint against America – these days, I have way too many.

Yes, I also think that Giuliani was the #1 person who showed his qualities as a leader after 9/11. As a leader, history turned him into a hero. He may have lost the primaries because of his highly imperfect image as a family man (be sure that the Czech voters have much more tolerance in all these matters!) or due to something else, who knows. John McCain was a lousy candidate and he is still a lousy politician but he was what the GOP finally offered.

Hawking wins the "best male actor" Oscar

Eddie Redmayne did a great job in "TOE"

The Theory of Everything (2014) is coming to the Czech movie theaters this week. Those of us who have mastered the space and time have already seen the picture. The touching film is based on "Travelling to Infinity: My Life with Stephen" by Jane Wilde Hawking, the famous physicist's first wife, which is a reason to expect fewer path integrals and more of the social stuff.

Even Stephen Hawking himself has pointed out that Eddie Redmayne was almost as handsome as himself (Hawking) so you shouldn't be surprised that this actor added the Oscar for the "best actor" last night, next to his Golden Globe for the "best actor" as well similar awards from SAG and BAFTA.

In this way, Redmayne almost became more famous than Hawking himself for a while. Before I would allow something like that, I would carefully test Redmayne's abilities to compute path integrals and emitted radiation within quantum field theory on curved backgrounds. Would he continue to be as great as Hawking himself?

The $15 million budget movie has earned $100+ million so far, not bad, and I must say that this success is impressive for the writer of the book, Jane Hawking herself. In some sense, you could say that the first woman who marries a young Stephen Hawking is a "random educated woman" and the random educated woman's ability to write a book that produces a $100 million box office movie seems like a coincidence. Well, I admit that the fact that she has a famous man to write about may have helped, too.

Many worlds: a Rozali-Carroll exchange

Sean Carroll wrote another tirade,

The Wrong Objections to the Many-Worlds Interpretation of Quantum Mechanics
where he tries to defend some misconceptions about the "many worlds interpretation" of quantum mechanics while showing that he is totally unable and unwilling to think rationally and honestly.

After some vacuous replies to vacuous complaints by vacuous critics who love to say that physics isn't testable, he claims that the following two assumptions,
  1. The world is described by a quantum state, which is an element of a kind of vector space known as Hilbert space.
  2. The quantum state evolves through time in accordance with the Schrödinger equation, with some particular Hamiltonian.
imply that the worlds where other outcomes of quantum measurements materialized must be as "real" as our branch of this network of parallel world. This claim is self-evidently untrue. Quantum mechanics – as understood for 90 years – says that no such words "really" exist (they can't even be well-defined in any way) even though the theory respects the postulates.

So Carroll's claim is equivalent to saying that \(12\times 2 = 1917\) because \(1+1=2\) and \(2+3=5\). Sorry but this would-be "derivation" is completely wrong.

Barry Kripke wrote a paper on light-cone-quantized string theory

In the S08E15 episode of The Big Bang Theory, Ms Wolowitz died. The characters were sad and Sheldon was the first one who said something touching. I think it was a decent way to deal with the real-world death of Carol Ann Susi who provided Ms Wolowitz with her voice.

The departure of Ms Wolowitz abruptly solved a jealousy-ignited argument between Stewart and Howard revolving around the furniture from the Wolowitz house.

Also, if you missed that, Penny learned that she's been getting tests from Amy who was comparing her intelligence to the intelligence of the chimps. Penny did pretty well, probably more so than Leonard.

Bridge loan to default or haircut is an oxymoron

No sane person deliberately builds bridges to nowhere

The new Greek Marxist prime minister didn't receive his bonuses for being at work on time which is why he only sent his letter, originally planned for Wednesday, on Thursday. As I described in some detail in a successful comment on LOL, what we got was a variation of Spoiled Little Joe's Letter to Baby Jesus. ;-)

Odds are 98% that you don't speak Czech. In his letter, little Joe is increasingly upset and obscene because he is not satisfied with what he found under the Christmas tree.

To summarize the letter, Tsipras wants to get a six-month "bridge loan", a kind of fellowship for himself and almost 11 million other Greeks dependent on the Greek state, before Greece and the ECB and the European lenders (and IMF?) will figure out an idea how to abolish or significantly reduce the debt and how to cut all the strings that were attached to the bailouts. During the six months, the Greek government will be allowed to continue in its insane Marxist policies, revert all pro-growth and pro-austerity reforms, stop privatization, rehire all the useless government employees, increase pensions, salaries, and so on.

That's a very amusing proposal to make the lenders happy, indeed.

A good story on proofs of inevitability of string theory

Natalie Wolchover is one of the best popular physics writers in the world, having written insightful stories especially for the Simons Foundation and the Quanta Magazine (her Bc degree in nonlinear optics from Tufts helps). Yesterday, she added

In Fake Universes, Evidence for String Theory
It is a wonderful article about the history of string theory (Veneziano-related history; thunderstorms by which God unsuccessfully tried to kill Green and Schwarz in Aspen, Colorado, which would postpone the First Superstring Revolution by a century; dualities; AdS/CFT etc.) with a modern focus on the research attempting to prove the uniqueness of string theory.

At least since the 1980s, we were saying that "string theory is the only game in town". This slogan was almost universally understood as a statement about the sociology or comparative literature. If you look at proposals for a quantum theory of gravity, aside from string theory, you won't find any that work.

Players in Greece, Ukraine get tougher

It's been five days since the latest blog post about Greece and Ukraine. Since that time, people got increasingly used to negotiations but their positions toughened, too.

The screenshot above comes from CNN. Just a few days earlier, an on-screen text in the same station talked about arms for "pro-U.S." troops in Ukraine. Now, we got a map where Crimea and Ukraine finally belong to the same country again and the country's name is Russia. Either quality control must be completely absent at CNN or these blunders are a new strategy to increase their visibility.

ATLAS, CMS: small SUSY deviations

Both ATLAS and CMS, the two main detectors at the Large Hadron Collider, published some preprints about the search for SUSY or new SUSY-like Higgs bosons. No formidable deviation from the Standard Model was found. However...

ATLAS was looking for a CP-odd Higgs boson, \(A\), in decays to \(Zh\). It turned out that there is approximately a 2.5-sigma excess for \(m_A=220\GeV\): look in the conclusions. I won't seriously mention the below-2-sigma excess for \(m_A=260\GeV\) at all.

BBC friendly towards gluinos at LHC

After Two Years' Vacation, the Large Hadron Collider will be restarted next month. At least since the discovery of the Higgs boson, most of the readers of mainstream media were overwhelmed by tirades against modern particle physics – especially supersymmetry and similar things. The writers of such stories have often emulated assorted Shwolins and Shmoits in effect, if not in intent.

Gluino vampire alchemist. The doll only costs $690, below several billions needed for a chance to see the much smaller gluino at the LHC.

Well, ATLAS' new (deputy) spokeswoman Beate Heinemann of UC Berkeley (Gianotti is superseding Heuer as CERN's director general) made a difference today and several stories that she inspired at visible places have conveyed the excitement in the particle physics community and the nonzero chance that a bigger discovery than the Higgs boson may be made in 2015 – and perhaps announced at the SUSY-related conferences in August and September.

Anti-Jewish attacks: another reason why a strong Israel is vital

Last night, I watched Spielberg's 1993 movie Schindler's List about Oskar Schindler, a real historical figure and a German-speaking industrialist born in Svitavy, Moravia, one of the Czech lands (then Austria-Hungary), who was wealthy, an NSDAP member, and well connected, but who used all these virtues to turn his factories into shields for Jews against the Holocaust. He has saved about 1,000 lives.

Pilsen's Great Synagogue is the third largest synagogue in the world, after one in Jerusalem and another one in Budapest. Prague has had over 20 synagogues throughout the years.

It wasn't the only movie about these issues that I recently watched; the Pianist (2002) was another one. These stories about the treatment of the Jews by the Nazi society are heartbreaking. And every society making average and subpar members proud that they belong to the "right" 90% or 95% or 97% or 99% of the society annoys me, scares me, and disgusts me (yes, the number included the figures for the climate alarmists and the Occupy movement, too).

Meanwhile, in the real world, two innocent people were killed in Copenhagen yesterday: one Danish film director and one Jewish guard of the local Jewish community. The apparently Arab perpetrator, Omar El-Hussein, one inspired by the Charlie Hebdo attackers was shot dead later.
