Shady shady buyer of "vistomail.com". He sends emails as satoshi@vistomail.com without any disclaimers, Godlike.
He or someone with the same name is having some fun with the SEC: dockets.justia.com/docket/florida/flmdce/8:2023cv01638/416506 for "Securities Fraud".
The complaint: www.sec.gov/files/litigation/complaints/2023/comp25785.pdf (archive). Some pearls:
41. Elbanna told investors several other lies to gain investors’ trust. These included his claim that he had served in the U.S. Marines, when in reality he was discharged after just fifteen days of their thirteen-week recruit training. Elbanna claimed that he had worked at the U.S. National Security Agency (“NSA”). He further claimed that the NSA was aware of and participating in the Digital World Exchange enterprise. All of these claims were false.42. Perhaps most incredibly, after claiming that he had “been in blockchain technology since the beginning” and “in the cryptocurrency space almost since its inception” in the May 2018 and March 2019 Whitepapers, respectively, Elbanna told investors in a chat program in April 2019 that he “was one of the first 4 creators of BTC.” He went so far as to tell another investor that he was the pseudonymous inventor of bitcoin, Satoshi Nakamoto himself. These statements were also false. Elbanna later admitted that he was not involved in blockchain technology from its beginning, and that he “didn’t even really know much about crypto” in 2018, the year he launched the Digital World Exchange enterprise.
www.law360.com/articles/1803299/bogus-nsa-worker-to-pay-sec-2-2m-in-crypto-scam-case says he had to pay $2.2M to the SEC.
The documentary Bitconned from Netflix comes strongly to mind, www.imdb.com/title/tt30317302/. It is unbelieveable people would fall for that kind of thing, the founders are not even sophisticated. And on top of that he agrees to appear on a documentary!!! OMG.
Every Lie algebra has a unique single corresponding simply connected Lie group Updated 2025-01-10 +Created 1970-01-01
This simply connected is called the universal covering group.
Most of the helium in the Earth's atmosphere comes from alpha decay, since helium is lighter than air and naturally escapes out out of the atmosphere.
Wiki mentions that alpha decay is well modelled as a quantum tunnelling event, see also Geiger-Nuttall law.
As a result of that law, alpha particles have relatively little energy variation around 5 MeV or a speed of about 5% of the speed of light for any element, because the energy is inversely exponentially proportional to half-life. This is because:
- if the energy is much larger, decay is very fast and we don't have time to study the isotope
- if the energy is much smaller, decay is very rare and we don't have enough events to observe at all
- youtu.be/_f8zeEI0oys?t=796 George Gamow and Edward Condon proposed the quantum tunnelling explanation
- youtu.be/_f8zeEI0oys?t=1725 worked out example that predicts the half-life of polonium-210 based on its emission energy
Uranium emits them, you can see their mass to charge ratio under magnetic field and so deduce that they are electrons.
Caused by weak interaction TODO why/how.
The emitted electron kinetic energy is random from zero to a maximum value. The rest goes into a neutrino. This is how the neutrino was first discovered/observed indirectly. This is well illustrated in a decay scheme such as Figure "caesium-137 decay scheme".
Most commonly known as a byproduct radioactive decay.
Their energy is very high compared example to more common radiation such as visible spectrum, and there is a neat reason for that: it's because the strong force that binds nuclei is strong so transitions lead to large energy changes.
A decay scheme such as Figure "caesium-137 decay scheme" illustrates well how gamma radiation happens as a byproduct of radioactive decay due to the existence of nuclear isomer.
Gamma rays are pretty cool as they give us insight into the energy levels/different configurations of the nucleus.
They have also been used as early sources of high energy particles for particle physics experiments before the development of particle accelerators, serving a similar purpose to cosmic rays in those early days.
But gamma rays they were more convenient in some cases because you could more easily manage them inside a laboratory rather than have to go climb some bloody mountain or a balloon.
The positron for example was first observed on cosmic rays, but better confirmed in gamma ray experiments by Carl David Anderson.

This seems like a cool dude. Besides a hardcore scientist, he also made many important contributions to the French education and research system.
