The times they are a changing
Shame on you if you don't know the original... go read some Hemingway. For Whom the Bell Tolls is a good start.
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.
