Скачать или смотреть Bryan Roberts (London School of Economics): Time reversal

Geneva, 13 March 2019


Abstract: What does it mean to “reverse time”? The idea sounds sci-fi, but plays an essential role in modern physics. This talk begins with an easy-going overview of how physicists understand time reversal, how it’s related to the philosophy of time and its direction, and why all this matters. I then review a competing, seemingly-intuitive philosophical account of time reversal, but which concludes that physicists have been wrong about it for a hundred years. I finally argue that we should resist this competing account, and stick with the physicists on the meaning of time reversal, both from a philosopher’s and from a physicist’s point of view.
