The #Universe is suspiciously like a Computer Simulation, #Physicist says.

The Universe Is 'Suspiciously'...

@bud_t @nrao_hamradio @thenrao @ARDC @NSF My uncle Bill was a #physicist at #Wright-Patterson Air Force Base. I wonder if he worked on anything #nsf-related. 🤔 3/

Can a #physicist please explain how something can be both a force and a particle?

#Nobel laureate Leon Cooper (1930 - 2024) in his office at Brown University in 1967. He was a #physicist who created the theory of how #superconductivity works. I finally identified the #calculator on his desk. It is a Smith Corona Marchant. A rebadged German made Diehl Transmatic S. It is electro-mechanical.

An office with a calculator on the corner of the desk.

Debate erupts around #Microsoft’s #quantumcomputing claims
#Physicists cast doubt on #Majorana1 chip
Henry Legg, #physicist at Univ of St. Andrews who had two preprints challenging the work, attacked. “It doesn’t look like Majoranas, at least to me,” Legg said. “Any company claiming to have a topological qubit in 2025 is essentially selling a fairy tale [that] undermines the field of #quantum computation … and public confidence in science.”

My 8 year old asked what would happen if you take the atmosphere clone it and put it at the edge of our current atmosphere. And I find that insanely nerd and need #scientist help. I'd assume earth's gravity would pull the new atmosphere in and thus making the pressure go up. But how much? What else?

#physics #physicists #physicist

In 1956 #physicist Leon Cooper published a theory of how #superconductivity works. The electrons in a conductor become bound together to form Cooper pairs. This is the second, hand written, draft of his paper. #manuscript #quantum

The first page of a manuscript describing the mechanism of superconductivity. It is partially typed, but mostly handwritten. There are a few words crossed off and others inserted.

This bugs the physicist in me each time I see this... WTF is "low side current monitoring"? I remember vaguely understanding it once but I forgot...

C'est comme les amplis différentiels qui ne sont pas vraiment différentiels (ils ne mesurent pas la différence de potentiel entre leurs entrées V+ et V-), pour ça, il faut un "instrumentation amplifier" 🤦‍♂️ <sigh> ah les ingénieurs...

Happy birthday to British #engineer, #mathematician, #physicist & #inventor Hertha Ayrton (1854-1923). I’ve shown her in my #linocut with a diagram of the dividers from her 1st of 26 (!) patents, one of her diagrams about the origin & growth of ripple marks & one of her diagrams of an electric arc lamp (a subject on which she literally wrote the textbook).⁠

Born Phoebe Sarah Marks, she was the 3rd of 8 children 🧵

Linocut portrait of Hertha Ayrton, surrounded by her diagrams and some of her inventions, printed in a gradient of red to purple. Ayrton, a middle age woman with a lot of curly hair, stands with her fingertips on a tabletop, looking right, in a loose dress. Her dress is red and colours change radially out to purple. To her left and above her are a series of horizontal sections showing the formation of ripples on a beach. Above her to the right is a diagram of her dividers from her patent. To the lower right is a cross-section of an arc-lamp.

Born on this day: #physicist J. R. Oppenheimer (1904-1967). While best remembered for his role in the Manhattan Project, he was a giant of 20th century theoretical physics, nominated for a Nobel 3 times. ⁠
⁠
In 1927 he & Max Born greatly simplified how we predict electrons behaviour within atoms. The Born-Oppenheimer or adiabatic approximation is based on the observation that electrons are 1000s times lighter than nuclei, 🧵1/n

Contrary to popular belief, #mathematician s and theoretical #physicist s don't just discuss their theories on blackboards all day, but much of the research in practice involves #software and coding. Recently, I started using #PariGP , which is an #opensource algebra system that has existed since the 1980s but is still being actively developed today. It has amazing abilities in the realm of number theory, all sorts of modulus and p-adic computations, etc. I use it because it is very fast in handling power series and polynomials. Of course, it can deal with big rational numbers and arbitrary precision float.
I recommend reading the "GP tutorial" pdf. It is one of the most entertaining tutorials I have done in a long time, written in a subtle funny way 😄. https://pari.math.u-bordeaux.fr/doc.html

#KnowledgeByte: Ettore Majorana was a Brilliant Italian theoretical #Physicist who worked on #Neutrino masses.

Majorana disappeared under mysterious circumstances on March 25, 1938, after purchasing a ticket to travel by ship from Palermo to Naples.

Happy birthday to French mathematician, physicist and philosopher Marie-Sophie Germain (1776 – 1831), known as Sophie. She taught herself mathematics using books in her father’s library and by corresponding with leading mathematicians of her day, including Lagrange, Legendre and Gauss, initially using the pseudonym Monsieur LeBlanc. 🧵1/n

Linocut of Sophie Germain (a young woman in with a collar with bow, under a dark dress, with a ribbon tied around her neck, long hair with centre part, half tied up with a ribbon in her hair). She is printed in dark blue with her own words about Fermat's Last Theorem in her own script carved into her hair and dress). Behind her in lavender is a grid of Chladni figures.
