Episode 108 of 475 episodes
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.
