So you want to be an astrophysicist?
Yet more science blogging. All the cool kids are doing it.
Steinn SigurĂ°sson is an astrophysicst at Penn State, with a new blog called
Dynamics of Cats. He already has some good posts up on the crucial question of how to become an astrophysicist:
Part 0,
Part 1.5. Okay, so he's an astrophysicist, not a mathematician.
I should also point you to
Electron Blue, where Pyracantha explains how your world-view changes when you begin to think in terms of vectors. I would describe it as a shift from Aristotelian to Galilean intuition -- the world is a different place once you've internalized the conservation of momentum. Quantum mechanics is another shift entirely.
And another thing: as mentioned in the
comments to the previous post, Kriston at Grammar.police found some great
negatively-curved spaces, made of yarn. (For mathematical details see section 3.9 of
Spacetime and Geometry.)
