「 Einstein's "model of gravity has been essential for everything from theorizing the Big Bang to photographing black holes," said lead author and Waterloo mathematical physics graduate Robin Wen in a statement about the research. "But when we try to understand gravity on a cosmic scale, at the scale of galaxy clusters and beyond, we encounter apparent inconsistencies with the predictions of general relativity." 」
Ein Physiker als Kapitalismuskritiker: Albert #Einstein veröffentlichte am 1. Mai 1949 einen Artikel unter dem Titel «Why Socialism» in der ersten Ausgabe der linken US-amerikanischen Zeitschrift «Monthly Review».
#OTD in 1905. Albert Einstein completes his doctoral thesis at the University of Zurich.
Titled "Eine neue Bestimmung der Moleküldimensionen", he calculated the size of sugar molecules in solution and from this a value for the Avogadro constant. It is related to his work on Brownian motion, published in the same year, and supported the atomic hypothesis, which was still controversial among leading physicists at the time.
1905 Einstein approached Kleiner with a thesis on the electrodynamics of
moving bodies. It was rejected because a) the professors who reviewed it didn't
really understand it, and b) it was purely theoretical in nature.
Einstein His Space and Times by Steven Gimbel, 2015
Steven Gimbel's biography presents Einstein in the context of the world he lived in, offering a fascinating portrait of a remarkable individual who remained actively engaged in international affairs throughout his life.
It’s now thought that they could illuminate fundamental questions in #physics, settle questions about #Einstein’s theories, & even help explain the #universe.
…In recent yrs, the amt of data that scientists have discovered about black holes has grown exponentially.
It’s in these simple, outlandish objects, Broderick explained,“that 20th-cen #physics breaks down.”…Basically, there’s #Einstein’s theory of general #relativity (which made a tiny but far-reaching correction to #Newton’s concept of #gravity), & there’s #QuantumMechanics. “General relativity is thought of as the theory of the very large & massive, & quantum mechanics is the theory of the very small or very cold,” Broderick said. #BlackHoles are massive(gen relativity), & cold (quantum mechanics).
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 wanted a free, bi-national Palestine in which Jews and Arabs shared sovereignty, living peacefully and equally with each other.
Technological progress frequently results in more unemployment rather than in an easing of the burden of work for all. The profit motive, in conjunction with competition among capitalists, is responsible for an instability in the accumulation and utilization of capital which leads to increasingly severe depressions. Unlimited competition leads to a huge waste of labor, and to that crippling of the social consciousness of individuals.
Watching the BBC documentary on #einstein via #netflix. Transparently obvious that this was made because of #Oppenheimer, but at the same time it’s an interesting overview of Einstein’s life between exile from Germany and turning up in the US.
I also thought they were taking liberties with his voice until they showed a clip of the real Einstein speaking. Turns out not so much, though I kinda want to watch more of that now.
