In which we look at relativistic rockets, scientific revolutions, and the mathematical connection between entanglement and nonlocality.<\/p>\n
Science fiction writers can make use of worm holes or warp drives to overcome this restriction, but it is not clear that such things can ever be made to work in reality. Another way to get around the problem may be to use the relativistic effects of time dilation and length contraction to cover large distances within a reasonable time span for those aboard a space ship. If a rocket accelerates at 1g (9.81 m\/s2) the crew will experience the equivalent of a gravitational field with the same strength as that on Earth. If this could be maintained for long enough they would eventually receive the benefits of the relativistic effects which improve the effective rate of travel. What then, are the appropriate equations for the relativistic rocket?<\/p>\n<\/li>\n
I finally wore Kuhn down, and in February 1991 I interviewed him for more than three hours in his cluttered office. He was one of the most ambiguous, ambivalent thinkers I have ever encountered, which helps explain why he is still interpreted in so many divergent and even contradictory ways. Whatever you may think of Kuhn, his view of science has become \u201ca permanent part of the repertoire of historians and philosophers and people in science studies in general,\u201d as philosopher Ian Hacking, editor of a new edition of Structure, recently told Scientific American\u2019s Gary Stix. To commemorate the 50th anniversary of Structure, I\u2019m posting an edited version of my write-up of Kuhn in The End of Science (Addison Wesley, 1996), which draws heavily on my meeting with him. I hope that this profile\u2014which is longer and more critical of Kuhn than \u201cReluctant Revolutionary,\u201d my May 1991 profile for Scientific American\u2014provides insights into the complicated views of this complicated man.<\/p>\n<\/li>\n
Entanglement and nonlocality are two of the main concepts studied in the quantum information sciences. Although it is immediately clear that entanglement is necessary for nonlocality, a detailed quantitative relation between these two concepts is not yet established. Writing in Physical Review Letters, Francesco Buscemi of the University of Nagoya, Japan, makes important progress in this direction<\/p>\n<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"
