Very well done presentation about the physics and observations of solar flares at the CfA.  Beautiful images, too.  If you have some interest in the subject and time to kill, take a look!

Hornblower, interesting! But about that spreading into the genepool thing, two organisms with different "code laugages" shouldn't be able to interact genetically and produce any kind of offspring.

Another great video by Veritasium, on the cognitive-experiential model of thinking.  Cool subject and fairly close to home to me as several faculty at my university do research in this area (particularly in how it applies to physics education.)

Watsisname, nice video!

Boom!  Solved.  (Using the template space-time diagram they provide in the description makes this a lot easier, and you should indeed find the Paradox ship, in the Annihilator ship's frame, is going backwards in time.)
