Shuttle - damage and modeling
It was a warning that a large fraction of the hardware was being set aside for shuttle tile damage modeling, maybe, starting today. Hope it really is ok, hope the models show correctly that it is ok.
Speculations on astronomy, astrophysics, news I find interesting,
theoretical issues, science and science policy.
In particular: gravitational radiation sources, black holes, planets and astrobiology.
I will digress into computational physics, science fiction and general issues and basically whatever I feel like whenever.
And, of course, cats.
