... The aim of this workshop is to get together theorists, who develop models leading to such cosmic polarization rotation (CPR), and experimentalists, who search for CPR using a variety of complementary methods, in order to discuss current results and future directions. The workshop will take place at the Villa Il Gioiello on the Arcetri hill near Florence, where Galileo, the first scientists to test the equivalence principle, spent the last 10 years of his life. ...

... The following tables summarize basic properties of the two echelle gratings. ... At the center of each order, the dispersion is 3.0 km s-1 per diode, at the long-wavelength end of each order it is 2.9 km s-1 per diode, and at the short-wavelength end of each order it is 3.1 km s-1 per diode. ... The figure below shows the echelle blaze function (also known as the "Ripple Function") in the form of sensitivity relative to the peak of the blaze as the product of wavelength and order number. ...

... 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. ...
