... Bad Astronomy . ... I think I will break from my usual format of Bad Astronomy/ Good Astronomy by saying that the way we define seasons currently is not strictly bad, but I feel (in my opinion!) that it could be better. The definition of when the seasons begin is at the moment of solstice or equinox; that is, winter (in the north) starts on December 22 nd and summer starts on June 22 nd . ... Now imagine breaking up the Sun's 46 degree up-and-down yearly swing into 1 day intervals. ...

. The elementary methods (that is, the use of real analysis vs. complex analysis) have a long history from Chebyshev to modern times. They lead to great achievements, due to Erdos, Selberg, Bombieri, etc. I recently started a thorough study of these methods, in order to understand their scope. In the talk, I will give a quick survey of this field, and some new observations. Go to the Laboratoire Poncelet home page. Site design by Paul Zinn-Justin

... All the galaxies are divided into 4 groups depending on the environment type; every subsample contains more than 10 galaxies. ... An effect of environments is seen both for the nuclei and for the bulges: if we consider the clusters (Virgo and Ursa Ma jor) and group centers as dense environments and the field and group periphery as sparse environments, then in the dense environments the stellar populations of S0s are in average older by 4­5 Gyr than in the sparse ones. ...
