Cze��, Rewording what I said on Friday, this is a lecture course where instead of exams, the lecturer asks you to play games. :) Witam, zagrajcie! http://humber.northnet.org/weeks/TorusGames/ For those absent on Fri 8 Mar: we did a review of curvature for new people, and then a quick introduction to topology. This Friday (15 marca) I propose to get back to curvature (or more strictly speaking, to the metric parameters, which include Omega_m, Omega_Lambda and... w_Q, the quintessence parameter) and to explain what Staszek, Gary and I did in: http://de.arXiv.org/abs/astro-ph/0106135 and what I think can be done better and with other public data sets. I think this should be enough to give everyone a feel for what needs to be and/or can be done, and I propose that the following Friday, 22 March, we make a decision on which shape-of-the-Universe project we wish to carry out, and start discussing how to organise this, conceptual questions, programming concepts, etc. Pozdrawiam Boud PS: Pami�tajcie: ta lista jest dla wszysce - wszystko mo�e pisa� na liscie!
