Quantum Physics of Chemical Energy: Endothermic & Exothermic Reactions
SUMMARY
In this video, I show Why Some Reactions EXPLODE and Others COOL: Root Cause of Chemical EnergyI I show how the chemistry behind endothermic and exothermic reactions can be traced to the underlying quantum...

Why Are Unstable Neutrons Everywhere?
Why to neutrons exist? You may say, this is a silly question. But the problem is that we know that free neutrons are unstable. This means that if you isolate a neutron by itself, after about 15 minutes, it will...

How Black Holes, Neutron Stars, and White Dwarfs Are Formed
SUMMARY
The universe is full of opposing forces balanced in a celestial tug-of-war, until they sometimes aren’t. In stars, the two opposing forces are gravity which tries to collapse the star inward, and...

Professor Dave Explains
Quantum Numbers, Atomic Orbitals, and Electron Configurations
Orbitals! Oh no. They're so weird. Don't worry, nobody understands these in first-year chemistry. You just pretend to, and then in second-year you learn them a little better, the following year a little better, and once you have a PhD...
