Comment Hierarchy as dimension (Score -1) 465

Grigori Perelman: Here, the parameter is not time, but scale â" and our space is modeled not by a manifold with a metric, but by a hierarchy of manifolds and metrics connected by the Ricci flow equation. This mathematics belongs to the new century and the new millennium, but the notion of a hierarchy of metrics would have pleased Riemann. Note that we have a paradox here: the regions that appear to be far from each other at a large distance scale may become close at a smaller distance scale; moreover if we allow Ricci flow through singularities, the regions that are in different connected components at a larger distance scale may become neighboring...

Submission + - Ask Slashdot: Can companies force employees to join social networks? (blogspot.com) 3

rubeon writes: "Companies can get a lot of mileage out of social networking services from the likes of Google or Facebook. Chat, document collaboration, and video conferencing using services like Google+ Hangouts or Facebook's Skype are seductive additions to an IT arsenal. But a lot of people have privacy concerns about these services, and there's no shortage of horror stories how these sites track and exploit their users' habits. Can a company force its employees to use Google+?"

`Is your faith that weak that it could be ruined if you admitted to yourself that Genesis is not a science text and cannot rationally be read literally?': the vast majority dismisses the Tanakh and the Gospels as un-solid, whether frankly or with deceit: that's a reason no to follow that opinion, because in this world, people, by their interactions, aggregate not around truth. For me these books, as `words', contain the most abstract concepts, which when made clear, should be of great benefit for mathematics (is Goldbach's problem solved? and that of the Continuum?). Consider what Perelman said about his trying to explain how could Jesus could walk on the waters (he suggests that he succeeded in his endeavors). Also, the greatest professed mathematicians were believers, monotheists (and tended to the same One). Among them one finds Pythagoras, Plato (yes he was acquainted with mathematics), Leibniz, Newton, Cantor, Goedel (note that Turing did not make a fundamental discovery, he just gave an adequate definition to the already known concept of `computable function of the integers' through is computors).
