Worth mentioning because of its irrelevance: that's my other choice for a post which points out a new preprint by H.Nielsen, the Danish physicist who became famous by hypothesizing that the future was influencing the past in order to prevent us from discovering the Higgs boson.

When I read back the piece I wrote back then ("Respectable physicists gone crackpotty") I cannot stop chuckling -I think it is one of my best posts ever. So I cannot even think of sitting down to write a similar one on the new work by Nielsen. You will have to find out by yourself to what heights the vagaries of the fellow have gotten.
