Low Mass Stars
Today we are talking about the life -- and death -- of stars. Low mass stars live a long time, fusing all their hydrogen into helium over a trillion years. More massive stars like the Sun live shorter lives. They fuse hydrogen into...

Legitimate Cold Fusion Exists | Muon-Catalyzed Fusion
This video is about the original cold fusion: μ muon-catalyzed cold fusion of deuterium, tritium, hydrogen, into helium-3 and helium 4. The problems with it are the half-life of muons and the sticking of muons to alpha particles. Also...

Ideal Gas Problems: Crash Course Chemistry
We don't live in a perfect world, and neither do gases - it would be great if their particles always fulfilled the assumptions of the ideal gas law, and we could use PV=nRT to get the right answer every time. Unfortunately, the ideal gas...

How the First Stars Transformed the Universe
The first stars turned all the neutral hydrogen in the universe back into ions, created a bunch of new elements, and just generally made a mess. But without them, you wouldn’t be here.
