| | | | | In our last primer we looked at a number of interesting examples of metric spaces, that is, spaces in which we can compute distance in a reasonable way. Our goal for this post is to relax this assumption. That is, we want to study the geometric structure of space without the ability to define distance. That is not to say that some notion of distance necessarily exists under the surface somewhere, but rather that we include a whole new class of spaces for which no notion of distance makes sense. | |

| | | | | Boris Tsirelson (or Cirel'son, or ?????????, or ?????????) is an Israeli (born Russian) mathematician currently at Tel-Aviv university. Here is the picture from his Wikipedia entry: he has such an incredible stare, he irresistibly reminds me of Orson Welles (picture below). Two great magicians! Tsirelson worked on the mathematical foundations of nonlocality in the early... | |

| | | | | Topology Quasi-polynomial algorithms for telling if a knot is trivial Marc Lackenby announced a quasi-polynomial time algorithm to decide whether a given knot is the unknot! This is a big breakthrough. This question is known to be both in NP and in coNP. See this post, and updates there in the comment section. Topology seminar,... | |
