Quantum mechanical theories aren't children of classical theories

In the "quantum foundations" category of blog posts, I have often discussed the thoroughly misguided and debunked philosophical misconceptions about the quantum character of reality – the opinion that the intrinsically probabilistic quantum mechanical framework is just an illusion that may be ignored and that a basically classical i.e. objective and/or deterministic set of laws of physics underlies all of reality.

People who love to write or shout the nonsense that there is something incomplete if not embarrassing about quantum mechanics are deluded. They typically think that they must be smarter than others if they're incapable of understanding the most important revolution in the 20th century science – one that took place in physics in the mid 1920s. Some of them are convinced that they are ahead of others if they still think about Nature in terms of the 17th century concepts.

It often looks like that these differences are only philosophical or speculative in nature. They don't affect the calculations, we are often told. Except that they do. Even when (and maybe especially when!) we talk about particular equations to calculate a quantity – and when we avoid debates about the meaning of all the concepts, the idea that some basically classical physics is "primary" creates problems.

John Tyndall: 195th birthday

Climate alarmists don't care about science which is why you can't find an alarmist blog that would remind its readers about the anniversary of the birth of one of the most important scientists who helped to establish the "greenhouse effect".

John Tyndall was born on August 2nd, 1820, to the wife of an Irish police constable. The family had emigrated from Southwest England. He got schooled in technical drawing and land surveying which was helpful in the mid 1840s when he was paid big bucks for railway planning during a train boom.

When he was 27, he felt rich enough and wanted to grow intellectually so he began to teach mathematics at a boarding school. Along with another young colleague, Edward Frankland, they realized that the Germans were a superior race when it came to experimental physics and chemistry. They moved to Marburg a year later. Hermann Knoblauch (German Garlic) became an important senior collaborator of Tyndall over there.

CMS bump at \(5\TeV\)?

First, off-topic: You may pre-order a book by Lisa Randall that will be out in 3 months (4 formats). It argues that dark matter is composed of organs of dinosaurs who were labeled reactionary autonomous intelligent weapons and shot into the outer space by mammoths. Well, I know the theory and the very interesting wisdom and stories around a bit more precisely than that because of some 50-hour exposure but there has to be a surprise left for you. ;-)



The ATLAS' bump at \(2\TeV\) or so – possibly a new gauge boson – is probably the most attractive excess the LHC teams are seeing in their data. However, Pauline Gagnon of ATLAS has ironically pointed out another pair of cute excesses seen by her competitors at the CMS:
The bumpy road to discoveries
Here are the two graphs:



Both graphs show the invariant masses of dijets – a dijet spectrum.

Windows 10: hours after upgrade from Windows 7

Just one day ago, I did want to wait for a long time before I upgrade my Windows 7 laptop to Windows 10. And I wanted to use about 4 "less important" computers of my relatives or friends as guinea pigs. ;-) But the feedback by the converted ones has been so surprisingly flawless that I did join the 14 million early, first-day adopters, after all, and my own computer was the first one that was upgraded. Note that the upgrade from Windows 7 or 8.1 to Windows 10 is free for 1 year. (You need to go from 8 to 8.1 first.)

And windows 10 is faster, better, and more modern.



If you are a Windows 7 or Windows 8.1 user, you are probably being offered an upgrade to Windows 10, the "final" version of Windows. (Windows 9 were skipped because 9 is too close to 8, a number that was considered a failure although I think that this bad rating was highly exaggerated.) Well, Microsoft has actually promised to stop the support of Windows 10 in October 2025 but let's not solve these distant future issues.

Does climate change break carbon dating?

No, we will just need a bit more complicated equations, and nuclear tests "broke" it 50 years ago, anyway

Windows 10: Off-topic. The last and best Windows, Windows 10, were released today. I have been offered to download the 3 GB file. But can some people tell me what are the threats? Will e.g. Mathematica work? Is it compatible with switchable graphics drivers? Omega 14.12 LeshCat? Will all the non-system folders that you created be preserved? Will the Windows gadgets that I could still preserve in Windows 7 disappear? Have any other apps gotten broken? Thanks for your answers.
According to the mythology, thousands of bad things are being caused by global warming. Some media have announced the 8200th victim of climate change. Let me borrow the titles from the Smithsonian Magazine and PBS:
Climate Change Might Break Carbon Dating

Fossil Fuels Are Destroying Our Ability to Study the Past
Terrible. Radiocarbon dating is becoming impossible! ExxonMobil has apparently destroyed archaeology. The Smithsonian subtitle is more fair: "Fossil fuel emissions mess with the ratio of carbon isotopes in the atmosphere." OK, what's going on? Is the era of radiocarbon dating really over?

Ask a question to Stephen Hawking

Stephen Hawking believes that artificial intelligence is dangerous: those robots may revolt and become our landlords. He co-authored a new letter with Elon Musk (text) demanding all man-made machines to be at least as stupid as a Tesla car to avoid "arms races" with the robots. Hawking himself has become much more powerful when his biological underpinnings have been enhanced by computer technology.

He must believe that he has become much more effective in answering people's questions. That's why he agreed to answer questions posted at reddit.com/r/science:

Science Ama Series: I am Stephen Hawking, theoretical physicist. Join me to talk about making the future of technology more human, reddit. AMA!
So far, there are over 8,000 comments over there.

Hillary's 500 million solar panels

In my opinion, Hillary Clinton is the most likely Democratic candidate to win the nomination and the most likely candidate to become the U.S. president. She's been moderate from many points of view. But she has apparently decided that a viable Democratic candidate needs the unhinged far-left base to win and because these extremists have largely adopted the most radical memes of the environmentalism, including the climate alarmism, as well, she decided to outline her great "renewable energy" plan.

Barack Obama had promised a similar plan to save the world and to stop the rise of the oceans in the Universe. Hillary Clinton is proposing her plan to reduce the workers' electricity bills. There are some similarities but you may see that Hillary is a bit more down-to-Earth.

Hillary, referring to herself as "just a grandmother with two eyes and a brain", decided to do the same thing as every lady whose husband prefers to bill-and-monicoo with other women: to reduce the CO2 emissions.
Well, maybe two eyes and a grandmother's brain aren't enough to find the actual solutions to any problems.

Barack Obama and Uhuru Kenyatta on gays in Kenya

Barack Obama has visited his fatherland, Kenya, and he didn't resist the temptation to promote one of the fads of the contemporary America, namely homosexualism (this is a favorite word of Czech ex-president Klaus; Kenyans surprisingly talk about gayism, too).



Kenya is a nation of 45 million people in East Africa. The official languages are English and Swahili. I actually found the response by their president, Uhuru Kenyatta, rather impressive. It sounds weird that this president's English and his rhetorical skills exceed those of any current top Czech politician.

Can oil companies be eliminating concerned Arctic researchers by lightnings?

In April 2013, I noticed that two of the co-authors of a paper about the Arctic accidentally died within a short period of time. A pretty lady collided with a truck while biking; and a man got drunk during a New Year Eve's party and fell from the staircase.



They were sad events but I semi-seriously proposed that those accidents weren't quite accidents.

Peter Wadhams, an old colleague of those folks who previously claimed that methane bubbles in the Arctic will erase 1/2 of the mankind's wealth, liked my idea and publicly articulated it yesterday. These people must have been assassinated by the "oil lobby workers".

TTIP: can there be EU-U.S. free trade?

I am actually surprised that the European Union is negotiating a free trade pact with the United States, TTIP (Transatlantic Trade and Investment Partnership). Effectively, the United States could join the most useful "layer" of the European Union, the European free trade zone.

For decades, the EU bureaucrats have been inventing increasingly complex regulations on names, genetically modified foods, concentration of one nutrient or another in each food, and so on, and so on. And suddenly, they would effectively allow the U.S. products that don't have to obey these conditions? Have they forgotten their past? Has there been a revolution in Brussels that has replaced socialists by free marketeers?

Obviously, as a free market champion, I am a defender of TTIP. The new competition could be threatening for some but it would be an advantage for others and the latter would prevail in the overall tally. Free trade makes growth faster. It pushes the people, companies, and nations to do things they're really good at. It gives the consumers more diverse options, more luxurious options, and/or cheaper options. And if corporations and consumers may become stronger relatively to the governments, it's surely good news.

How you surely can't recover information from a black hole

Lots of papers that make it to the arXiv these days (but maybe a minority) are completely wrong. Some of the most crazily wrong papers that make it through the arXiv filters are those that are soon hyped by the blogs and the media. That's also the case of the preprint

How to Recover a Qubit That Has Fallen Into a Black Hole
by Aidan Chatwin-Davies, Adam S. Jermyn, and Sean M. Carroll which has been "promoted" by a guest blog written by the first co-author on the blog of the third co-author. Holy cow. This short paper is just so incredibly wrong in such an incredibly stupid way!

Fearmongers threaten with attacks if Lomborg's center opens in Australia

Tony Abbott became Australia's prime minister in 2013 and since the beginning, he was aware of the utter irrationality in his country's and its universities' previous attitude to the "climate change" gospel. He wanted some scholars in his country who study topics such as related "global threats" rationally and honestly.

However, he doesn't quite have the balls so he didn't dare to open a center run by truly sensible people when it comes to these issues – climate realists. He wanted to appease the extreme left-wing activists who have contaminated almost every corner of the university environment. So his center had to be led by

  1. a lukewarmer, not a true climate skeptic
  2. someone with some other "minority" credentials, e.g. a gay
This puzzle had a unique solution: Bjorn Lomborg. So the Australian government decided to pay $4 million and establish a new research center that rationally studies "global problems", an Australian branch of Lomborg's Copenhagen Consensus Center.

Earth-like planet orbiting a Sun-like star

Could it harbor human-like aliens in Škoda-like cars?

Yesterday, NASA announced the discovery of the most accurate impersonation of the Earth-Sun system so far.



Kepler-452 is a G-class star (like the Sun) with almost the same surface temperature as the Sun, 10 percent larger in diameter, 4 percent larger in mass, and 20 percent brighter than the Sun. As you can see, it is almost the same thing as the Sun. But it is also 30% older than the Sun, about 6 billion years.

ECJ: utility discriminated against gypsies by making it harder for them to steal electricity

ČEZ is the dominant Czech power utility. More than 50% of the company is state-owned but the remaining stocks are enough to make ČEZ one of the two most intensely traded stocks at the Prague Stock Exchange.

ČEZ owns various power plants and grids in the post-socialist Europe, too. And a complaint in the Bulgarian town of Dupnica/Dupnitsa has led to a rather incredible EU court verdict (see the full judgment here) that has shocked those Czechs who cared.



Because my text would be almost identical to that of Dr George X [not Rachel] Doležal in the Reflex Magazine, I will translate his viewpoint instead.

George X. Doležal: ČEZ has discriminated against the Romani. It didn't let them steal power.

The European Court of Justice has made a groundbreaking verdict against our ČEZ. To steal electricity is, as the judges implicitly state, a democratic right. The provider of power isn't allowed to place any technical hurdles that would prevent the consumer from stealing electricity. If the provider does so, it is discrimination.

Žižkov rocket finally launched to space

Fun reading in the Guardian: life and personality of John Conway, the world's most charismatic mathematician
Russians and Americans are employing cosmodromes that are well-separated from the main centers of the civilization.

The #3 country in space research, the Czech Republic (recall that Czechoslovakia was also the #3 country with a man in space, Mr Vladimír Remek, now the Czech ambassador in Moscow), decided that this setup was uneconomic. That's why our modern cosmodrome was built in Prague, in the neighborhood of Žižkov [zhish-koff].



See Google Maps

This decision was made in order to simplify the inflow of cash, fuel, and signatures that are needed for cosmic operations.
