what was that about transition fossils...?
The Fish that crawled out of the water...
Nature reports a spectacular "transition" fossil, of a large fish showing partial adaptation for living on land.
And so it goes...
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.
