Dark matter source of cosmic ray positrons more likely: a paper

The old intriguing PAMELA experiment and perhaps newer ones by Fermi-LAT and AMS-02 have discovered lots of positrons – the antiparticles of electrons – in the cosmic rays whose flux is generally higher than expected. Such positrons may originate from dark matter and would amount to an "almost direct detection" of the particles that make up dark matter.

That would be very exciting. However, there may also be more boring, astrophysical, sources of these positrons, and pulsars in particular (magnetized neutron stars or white dwarfs emitting a beam of electromagnetic radiation). Some pieces of matter may emit lots of junk and these processes may be completely compatible with the Standard Model – i.e. just slightly more extreme than when you cook a food in your kitchen.

Margining Bitcoin futures is possible

I sold all my cryptocurrencies two days ago – the second SEPA transfer arrived to my bank from AnyCoinDirect.EU just 5 hours after my Ethereum payment which is rather incredible – and the time I waste by watching movements in the cryptocurrencies has dropped significantly. In fact, I believe that the mankind wastes an insane amount of time by watching the events and wiggles of the Bitcoin and this time multiplied by a minimum salary could easily trump the whole Bitcoin capitalization every year by itself.



CME should start the Bitcoin futures in the second week of December. As Coin Telegraph informed its readers, big investment VIP Thomas Peterffy wrote a letter saying that "it's impossible to margin such a [Bitcoin futures] product" and the unlimited swings, especially the upside swings threaten the broker and all of its clients who hold safe products, too. So these things should be isolated.

I agree with him that aside from some continuity, the Bitcoin prices are a sequence of basically random numbers where no reasonable limits may be placed on the day-to-day price changes etc. And I agree with him that this "asset" is immature and its advocates are financially illiterate imbeciles. But I don't quite agree that it's impossible to offer a safe product based on such flimsy foundations.

The most frustrating anniversary of Velvet Revolution since 1989

November 17th is a major Czech holiday. We celebrate the "Day of the Fight for Freedom and Democracy". This definition was a compromise codified by some lawmakers to point that the the celebration reminds us both of

  • November 17th, 1939, when Nazis closed the Czech universities in response to the anti-Nazi activities by the students, especially during the funeral of Mr Jan Opletal who was fatally injured during the previous October 28th (1918 anniversary) rally. For this reason, this day became the International Student Day, the only widely celebrated international holiday fully inspired by the modern Czech history. Communists celebrated that day as well – which is why it became softly but perhaps unfairly connected with their regime.
  • November 17th, 1989, when students of the Charles University in Prague (my Alma Mater) reminded themselves of the 50th anniversary of the event above. They were also dissatisfied with many things about the totalitarian regime, they were beaten by the police, and the protests against the police action kickstarted the Velvet Revolution i.e. the fall of communism in Czechoslovakia.
I only remember the latter rather well – and I actively participated in the events as a high school student. I have written numerous blog posts about the Velvet Revolution in previous years. It seems to me that I could take the basic changes made in 1989 for granted. In 2017, on the 28th anniversary, I am no longer confident.



Some really good 2017 time lapse video of Prague, by a Russian.

In the Parliament that arose from the most recent elections, about 1/2 of the lawmakers represent parties that openly prefer the communist regime over the post-1989 capitalism. As recently as one year ago, I was torturing myself with the nightmare of a coming government of the communist party (which hasn't participated in any government since the June 1990 elections, not even indirectly) and ANO, an anti-capitalist party led by a communist apparatchik and a communist secret agent who also became a billionaire because of his communist-era contacts, special knowledge, and his predator status based on the absolute absence of any morality (and because he escaped Slovakia before they would put him to jail for a long time).

Author of Czech tramping anthem dies

An hour ago, everyone was told that songmaker Mr Wabi Daněk died at 70. He has recorded lots of songs but the most famous one was his 1970 song "Dew on the Tracks".



It has become the anthem of the Czech tramping. Now, the word "tramp" surely sounds like a perfectly English word – sometimes, Czechs pronounce it "tramp", sometimes they read it like a Czech word, e.g. "trump" (which makes it even more relevant nowadays). I have heard or said the word every other day for 5 years before I learned how to say "I am" in English. ;-) Nevertheless, Wikipedia basically tells us that the word "tramping" is either from Czechia or from New Zealand, see a disambiguation page. Kiwis consider tramping to be "a style of backpacking".

Scandalous EU behavior towards Poland reminds us of the Third Reich

As various news outlets told us, the European Parliament approved a resolution slinging mud at Poland that may be used to launch the process against the member state.



The Polish anthem has the music (by an unknown composer) of the pan-Slavic anthem – check e.g. Hey Slavs, the Czech edition with Samuel Tomášik's lyrics (written in Czech by a Slovak priest who was terrified to hear so much German during his 1834 trip to Prague LOL), or the defunct Yugoslav anthem as well as the Slovak Clerofascist State's ruling party's anthem.

I am absolutely shocked by this development and especially its contrast with the EU's support for the recent Spanish fascist campaign against the basic civic rights of the Catalans. 438 "deputies" supported the resolution, 152 were against, 71 abstained. (Almost one-half of MEPs have bought by Soros and Soros brags that they became "reliable friends". Note that he recently gave shocking $18 billion to his sick Open Foundation. How many such sluts may he buy when there are many sluts who will work for $50?) Polish prime minister reacted on Twitter: she will discuss the "scandalous developments" in the European Parliament on Friday. Hungary has used the same adjective. The foreign minister was shocked by the debate
in the EU Parliament.

Escaping the crypto-world: links for you

During the recent months, I spent a lot of time with the cryptocurrencies – studying what they are technologically, economically, as well as sociologically, how the people feel, why they believe what they believe, and so on.

Tony was very kind and brought me to the crypto-world as a practical person, not just a theorist, by his generous donation denominated in the Bitcoin. About one-half of that donation quickly evaporated by random conversions and depreciation of Bitcoin Cash at some moment etc., it's a wild world. I converted one-half of the rest to the Czech currency and played with the remaining half – unfortunately, it was in the tetherized dollar during the recent big growth of the Bitcoin price.

Weinstein's view on quanta, geometry is upside down

Big Think has posted the following 10-minute monologue by Eric Weinstein, a trader working for Peter Thiel, the guy who is not the author of the Wolfram Mathworld (just a similar name, thanks psi_bar), a guy who promised us a theory of everything but all we got so far was some incoherent babbling, and the brother of a far left ex-professor who has nevertheless become a target of some of his approximate comrades, namely fanatical reverse racists in the Academia.



Weinstein says that in the recent 40 years, we've made a big progress in "mathematics of field theory" which was good for quantum field theory and general relativity. OK, one could perhaps summarize the progress in this way although I wouldn't. But in the following sentence, he complains that

we ended up geometrizing the quantum rather than quantizing gravity which we had wanted
and that's supposed to be "disappointing" because physicists only got a "golden age of mathematics of theoretical physics" rather than "golden age of theoretical physics". Wait a minute, this is quite a statement that deserves some commentary.

Bitcoin congestion singularity may be coming

The Bitcoin is under pressure since Friday.

According to CoinMarketCap.com, the Bitcoin Cash (BCH) – the cheaper, faster would-be main Bitcoin with bigger blocks that was created in August – is already the #1 cryptocurrency by trading volume – over $10 billion a day. Much of the trading takes place at Korean exchanges. But maybe it's not Koreans behind the purchases of Bitcoin Cash; it could be Chinese with accounts in Korea, too. Bitcoin Cash is also the #2 cryptocurrency after Bitcoin Core (BTC) by capitalization – ahead of Ethereum (although it's a statistical tie most of the day and ETH may occasionally get above BCH). I was always sure that it was the most promising cryptocurrency and held a lot in it – but I was too impatient and sold when it was $400. It's over $1,800 now. These changes aren't unusual.

The number of BTC unconfirmed transactions is around 160,000 – on Friday evening, it was already bad, 80,000 – doubling in less than two days. There are some 250,000 transactions on a weekend day. Clearly, the number is growing and I believe that by Monday, the unconfirmed transactions will actually surpass the 240,000 record high from May 2017.

An attack on BTC may be underway

A dangerous November 16th "SegWit2x" Bitcoin hard fork has been suspended indefinitely according to an e-mail by the organizers who were unhappy that they couldn't persuade the true Bitcoin cultists – which is basically impossible.



However, the widely perceived probability that the fork will take place anyway hasn't dropped to zero at all. The BT2 futures jumped above $300, more than by 50%, in the recent day, while the SegWit2x futures remain above $400. These two probably differ by their behavior if the fork doesn't occur at all. On top of that, a website bitcoin2x.org – which may be just bogus but publicly, nobody is sure – says that a group will proceed with the fork, anyway. And the user nicknamed BitPico has posted a message somewhere claiming that 30% of the miners will work on the SegWit2x fork.

Japanese planned ILC collider shrinks to half

In 2013, I discussed the Japanese competition choosing the host of the International Linear Collider



The folks in the Sefuri mountains who created this catchy music video lost and Tohoku won instead – those had more credible, respected, and boring physicists behind themselves, not to mention a 5 times longer video with the 20 times smaller number of views. ;-)

Brain-dead green nut jobs attack Kathleen Hartnett White

Donald Trump has nominated Kathleen Hartnett White, an experienced Texan female politician focusing on the environment, as the boss of the White House Council on Environmental Quality. She is a noted climate skeptic and a defender of CO2 and the energy industry. Last year, she and Stephen Moore wrote the book Fueling Freedom: Exposing the Mad War on Energy. CO2 is the gas of life, the fossil fuels basically ended the slavery, and so on. I agree with all these statements. Every sane person does.

But somewhat unsurprisingly yet still shockingly, White immediately became a target of a coordinated vicious attack by the far left, by insane brainwashed and brain-dead whackos who deny basic scientific facts such as the key role of CO2 in the life processes.

CME Bitcoin futures: rules, forecasts, recipes

Greatly reduced volatility, smooth exponential decrease of the Bitcoin price, regulators' and short sellers' profits, boredom, even higher Bitcoin fees, exodus

One week ago, I discussed the plan of the CME group to allow trading of Bitcoin futures. See a CME web page, a press release, and its review in Business Insider, underlying reference rates (BRR real-time and BRTI daily rate).



Last night, Business Insider brought us

[We just got] a glimpse of how bitcoin futures will work
There are many details over there. Let me look at them first.
