Einstein's quantum theory of the monatomic ideal gas: non-statistical arguments for a new statisticsIn this article, we analyze the third of three papers, in which Einstein presented his quantum theory of the ideal gas of 1924-1925. Although it failed to attract the attention of Einstein's…Enric Pérez, Tilman Sauer·Apr 30, 2010SaveLearn
Mirror Symmetry and Other Miracles in Superstring TheoryThe dominance of string theory in the research landscape of quantum gravity physics (despite any direct experimental evidence) can, I think, be justified in a variety of ways. Here I focus on an…Dean Rickles·Apr 26, 2010SaveLearn
Riccioli Measures the Stars: Observations of the telescopic disks of stars as evidence against Copernicus and Galileo in the middle of the 17th centuryG. B.
