After a quick Dragon*Con break, we’re back to our tour through the fundamental forces of the Universe. We’ve covered gravity and electromagnetism, and now we’re moving onto the strong and weak nuclear forces. We didn’t think they’d really need to be separate episodes, so we’re putting them together. And then we’ll cap the whole series with the quest for the theory of everything.

Ep 104: Science Fiction at Dragon*Con with Plait and Grazier
Pamela left Fraser behind (with sorrow) and took on Dragon*Con and the facts (or lack there of) in Science Fiction. Helping her out were special guests Phil Plait and Kevin Grazier.
Ep. 103: Electromagnetism
Our series on the basic forces of the cosmos continues! Last week we discussed gravity, and this we’ll handle electromagnetism. Electricity and magnetism are just two aspects of the same force, and you can’t talk about astronomy without understanding these two keys aspects of physics.
Ep 102: Gravity
You seem to like a nice series, so here’s a new one we’ve been thinking about. Over the course of the next 4 weeks, we’re going to cover each of the basic forces in the Universe. And this week, we’re going to start with gravity; the force you’re most familiar with. Gravity happens when masses attract one another, and we can calculate its effect with exquisite precision. But you might be surprised to know that scientists have no idea why gravity happens.
