Number Theory Days 2012

Since 2005, the number theorists at ETH Zürich and at EPF Lausanne organize every year the Number Theory Days, which present five talks, in all areas of number theory, over two days. (Actually, I’ve seen one web page claim that the tradition started in 2004, but I didn’t find any other reference for it…)

The 2012 edition will be held in Zürich on March 30 and 31, co-organized by Philippe Michel and myself, with the support of the FIM. Here is the official web page and the beautiful poster:

We especially encourage your researchers interested in attending (PhD students, postdocs, in particular) to write to the FIM coordinator, as indicated on the web page, to register, and to indicate if they wish to request funding for travel and local expenses.

Birds of the Léman

My last post about birds concerned the great crested grebe (which appears in a most hilarious way in Scoop — “Lord Copper,” he was saying, “no man shall call me a liar unchastised. The great crested grebe does hibernate.”)

Although a more recent week-end excursion on the Léman was richer in raptors, it was also a pleasure to watch the noble heron (Héron cendré, I guess) guarding the piers:

However, the thrilling part was to watch raptors fishing; to be precise, I think most of them were the same species

which — interpreting my bird-book — is quite likely to be the Milan noir (Milvus migrans) (it might be the Milan royal, but that seems much more unlikely). Of course, most of my attempts to photograph the fishing of the milans resulted in blurry pictures of the surface of the lake; however, some succeeded, like this one
