Conservation of Nucleon Number
In this video Paul Andersen explains how the nucleon number and charge is conserved in all nuclear reactions and radioactive decay. Fission, fusion, alpha decay, beta decay, and gamma decay all conserve the number of neutrons and...

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.

Wave-Particle Duality - Part 2
In this video Paul Andersen explains how classical waves (like light) can have particle properties. Albert Einsetein used the photoelectric effect to show how photons have particle properties.

These Stars Are Being Eaten Alive from the Inside
In general, a star’s size will determine its final destiny. Some stars fizzle out, while others explode, and what seals their fate may come down to a curious, cannibalistic process happening inside their cores!

Conservation of Charge in Reactions
In this video Paul Andersen explains how the charge is conserved in nuclear reactions. When elementary particles are created or destroyed in a reaction the net change in charge will remain constant. Alpha, beta -, and beta+ decay are...
