…used in his fascinating Cube Explorer software (which you can download for free). However, to produce his most recent results, Rokicki had to head over to Sony Pictures Imageworks. Sony lent Rokicki their super-computers during the idle-time between productions, which allowed him to grind through cube positions much more quickly. Yes, the very same computers that brought you Spiderman 3 now bring you “God’s Algorithm” for the Rubik’s Cube. Unfortu…

Later, I’ll sketch a little bit of the first answer to this challenge, which was given by Pierre de Fermat in an obscure letter to Gassendi, arou…

…aeons in Penrose’s Conformal-Cyclic-Cosmology — indeed, this is apparently required in order to glue the aeons together smoothly. A remaining question, of course, is whether or not this is related in any useful way to the Boltzmann entropy on the scale of every-day objects… Second: the black-hole information paradox. As I’ve ranted before: black hole evaporation isn’t really a paradox, but rather a case where many physicists are demanding a more “…
