A National Institute for Occupational Safety and Health study, published in March, found that professional American football (NFL) players lived longer, on average, than similar "mere mortals" in the
general population.

Summary: HEIGHT REDUCING PROBLEM ON ALGEBRAIC
Abstract. Let be an algebraic integer and assume that it is expanding,
i.e., its all conjugates lie outside the unit circle. We show several results
of the form Z[] = B[] with a certain finite set B Z. This property is
called height reducing property, which attracted specia... | {"url":"http://www.osti.gov/eprints/topicpages/documents/record/023/4267904.html","timestamp":"2014-04-21T05:33:12Z","content_type":null,"content_length":"8184","record_id":"<urn:uuid:4acd241a-6abe-4da5-9581-1ec757583816>","cc-path":"CC-MAIN-2014-15/segments/1397609539493.17/warc/CC-MAIN-20140416005219-00160-ip-10-147-... |

Acute triangulation

Assume that $S$ is a finite 2-dimensional simplicial complex equipped with a metric $d$ such that each triangle is isometric to a plane triangle (so $(S,d)$ is a polyhedral space).
Is it possible to subdivide the triangulation of $S$ so that it will have acute trian... | {"url":"http://mathoverflow.net/questions/96988/acute-triangulation/96998","timestamp":"2014-04-21T15:16:15Z","content_type":null,"content_length":"58219","record_id":"<urn:uuid:00922a0a-9eee-49a6-a574-28a1856970f1>","cc-path":"CC-MAIN-2014-15/segments/1398223202457.0/warc/CC-MAIN-20140423032002-00656-ip-10-147-4-33.ec... |

The Effectiveness of Group Theory in Quantum Mechanics
Eugene Wigner and Hermann Weyl led the way in applying the theory of group representations to the newly formulated theory of quantum mechanics starting in 1927. My talk will focus, first, on two
