If you know anything about the subject you would know that "Das Relativitatsprinzip” was "the first account of Minkowski’s ideas on Special Relativity and 4-dimensional geometry. It is striking that, in this text, Poincare’s name is among the most cited ones: more precisely, the three most cited names are Planck (cited eleven times), Lorentz (cited ten times) and Poincare (cited six times). By contrast, Einstein’s name appears only twice."<br />https://arxiv.org/pdf/0807.1300.pdf<br /><br />Don't waste my time anonymous coward.Matthew Corynoreply@blogger.comtag:blogger.com,1999:blog-8148573551417578681.post-41948917403658172262016-10-25T17:12:47.750-07:002016-10-25T17:12:47.750-07:00Wrong.

You don't get the math.<br /><br />I'll repeat my post to Motl with quotes from Roger and others:<br /><br />The more I read about Einstein, the more I realize his following is a cult. In terms of the geometrization of physics "many people assume that Einstein was a leader in this movement, but he was not. When Minkowski popularized the spacetime geometry in 1908, Einstein rejected it. When Grossmann figured out to geometrize gravity with the Ricci tensor, Einstein wrote papers in 1914 saying that covariance is impossible. When a relativity textbook described the geometrization of gravity, Einstein attacked it as wrongheaded.... In 1905, Poincare had the Lorentz group and the spacetime metric, and at the time a Klein geometry was understood in terms of a transformation group or an invariant metric. He also implicitly used the covariance of Maxwell's equations, thereby integrating the geometry with electromagnetism. Minkowski followed where Poincare left off, explicitly treating world-lines, non-Eudlidean geometry, and covariance. Einstein had none of that. He only had an exposition of Lorentz's theorem, not covariance or spacetime or geometry."<br /><br />...(see <a href="http://motls.blogspot.com/2015/05/reviewing-epr-sleeping-beauty-paper.html#comment-2615934058" rel="nofollow">post</a>)Matthew Coryhttps://twitter.com/Cory_MD888noreply@blogger.comtag:blogger.com,1999:blog-8148573551417578681.post-91520010015752618122016-10-23T06:36:05.981-07:002016-10-23T06:36:05.981-07:00"Poincare are discussed at length" - I..."Poincare are discussed at length" - I have just looked at the paper.

They can't design a language like Julia, a condensed develop environment like Squeak and just waste all our MIPS and graphics TFLOPS on bad programming. FPGAs have been around forever and no one uses them. I have been saying this forever, as well. Japan finally got the idiotic Westerners to pay attention: <br /><br />"Fujitsu says it has implemented basic optimisation circuits using an FPGA to handle combinations which can be expressed as 1024 bits, which when using a ‘simulated annealing’ process ran 10,000 times faster than conventional processors in terms of handling the aforementioned thorny combinatorial optimisation problems.<br /><br />The company says it will work on improving the architecture going forward, and by the fiscal year 2018, it expects 'to have prototype computational systems able to handle real-world problems of 100,000 bits to one million bits that it will validate on the path toward practical implementation'."<br /><br />http://www.techradar.com/news/forget-quantum-computing-fujitsu-has-a-better-ideaMatthew Coryhttps://twitter.com/Cory_MD888noreply@blogger.com
