Yet more science blogging. All the cool kids are doing it.<\/p>\n
Steinn Sigur\u00f0sson is an astrophysicst at Penn State, with a new blog called Dynamics of Cats<\/a>. He already has some good posts up on the crucial question of how to become an astrophysicist: Part 0<\/a>, Part 1.5<\/a>. Okay, so he’s an astrophysicist, not a mathematician. <\/p>\n I should also point you to Electron Blue<\/a>, 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.<\/p>\n And another thing: as mentioned in the comments<\/a> to the previous post, Kriston at Grammar.police found some great negatively-curved spaces<\/a>, made of yarn. (For mathematical details see section 3.9 of Spacetime and Geometry<\/a>.)<\/p>\n","protected":false},"excerpt":{"rendered":" Yet more science blogging. All the cool kids are doing it.
