Today in History, March 14, 1879, Albert Einstein was born. In addition to being one of the most significant physicists of all time, he was also a pacifist. Yet his letter to President Roosevelt warning of the Nazi progress on atomic weapons research was arguably key to the U.S. implementation of the Manhatton Project, a decision he later lamented. In 1955, well after the Cold War and nuclear arms race had begun, he and ten other intellectuals and scientists, including other Nobel Prize laureates, like Bertrand Russell and Linus Pauling, wrote a manifesto warning of the dangers of nuclear weapons. Einstein also participated in the U.S. Civil Rights movement, calling racism America’s “worst disease.” Later in his life he began to support socialism, and he criticized the Bolsheviks for their barbarism. Einstein was also a Zionist, and supported Jews’ right to return to Palestine. However, he did not support a Jewish state, or an Arab state, to replace Mandatory Palestine. Rather, he wanted a free, bi-national Palestine in which Jews and Arabs shared sovereignty, living peacefully and equally with each other.

Happy Pi Day, fediverse!

And since it's also Albert Einstein's birthday, here's a quote from his 1949 article "Why Socialism?":

"The economic anarchy of capitalist society as it exists today is, in my opinion, the real source of the evil."

He sure was a smart guy.

Purim fällt dieses Jahr ja mit Einstens Geburtstag zusammen, auf dessen Spuren ich grad "unterwegs" bin..Der hat ja viel gesagt, was derzeit sehr aktuell ist. Zum Beispiel: "Wer es in kleinen Dingen mit der Wahrheit nicht ernst nimmt, dem kann man auch in großen Dingen nicht vertrauen." Oder auch: "Die Welt wird nicht bedroht von den Menschen, die böse sind, sondern von denen, die das Böse zulassen." - in diesem Sinne: Verflucht seien alle Hamans: Happy Purim!

Did you know Albert Einstein wrote an essay titled "Why Socialism?" in 1949 for the Monthly Review? The FBI saw it as confirmation of his "Communist sympathies." Despite being against totalitarianism, he expressed his views in this essay.

#Pioneering female #Chinese #American physicist Chien-Shiung Wu, who worked with Robert #Oppenheimer on the #ManhattanProject, was also the first to confirm #QuantumEntanglement – just 14 years after Albert #Einstein questioned the phenomenon. The largely forgotten achievement was included in a profile of Wu, one of the most influential experimental physicists of the 20th century, published in the December 2024 issue of Physics Today.

Wu is also believed to have been the only Chinese scientist involved in the Manhattan Project, the World War II initiative to develop an #AtomicBomb led by Oppenheimer, who affectionately referred to her as Jiejie, which means elder sister, the article said.

Wu’s experiment – detailed in a paper published in 1950 – was conducted before the #scientific community had fully grasped the significance of quantum entanglement, the article noted.

This is an old animation I had on VHS. I animated the train part (30 yrs ago?) with Mathematica on my NeXTdimension cube (using the graphic board NTSC Composite outputs). I renumerized it back from tape lately and added the scrolling text. Et aujourd'hui j'ai accolé l'intro musicale. Reste plus qu'à mettre des bips bips sonores lors de l'arrivée des impulsions lumineuses dans la partie 'train'...

The #Einstein field equations:

Rμν - ½Rgμν + Λgμν = (8πG/c⁴)Tμν

He believed the universe was static and eternal, so he added the term with Lambda (Λ) to keep it from expanding or collapsing, which would have worked for about five minutes maybe, and in 1929 Edwin Hubble published evidence it was expanding in any event, so Einstein dropped the term and purportedly told George Gamow it was the biggest blunder of his life. Then in 1998 two rival teams of astronomers published evidence the expansion of the universe is 𝘢𝘤𝘤𝘦𝘭𝘦𝘳𝘢𝘵𝘪𝘯𝘨 so in the end taking the Lambda term 𝘰𝘶𝘵 was an even bigger blunder! Nowadays cosmology is best described by ΛCDM, the Lambda/Cold Dark Matter standard model. #1123

Einstein proved (w/ relativity):

* There is no absolute distance
* There is no absolute time
* There is no absolute velocity including "at rest"
* There is no absolute mass

However there is absolute acceleration (which is key to General Relativity). But what is cool is how it also shows even the fundamental forces arent absolute. A magnetic field arrises from an electric field due to relativity and vice versa. Very little is absolute but some things are, so cool...

Three good things about today:

Sunday, October 6

1. I saved 42% on my grocery bill through Albertson’s forU program of coupons and discounts.
2. I had my brain stretched by watching a Veritasium video about following Einstein’s math to predict the possible intersections of black holes, white holes, wormholes, and alternate universes. Link: https://youtu.be/6akmv1bsz1M?si=xnzXJUzX8g7wLnqq
3. I succeeded in making salmon with asparagus, rice, and corn+peas+carrots.
