Coulomb's Law
In this video Paul Andersen explains how we can use Coulomb's law to predict the structure of atoms. These predictions can be verified through the use of Photoelectron Spectroscopy (PES). Electron's are help around the nucleus because of...

Strong Interaction: The Four Fundamental Forces of Physics #1a
Part one of a four part series on the fundamental forces (or interactions) of physics begins with the strong force or strong interaction - which on the small scale holds quarks together to form protons, neutrons and other hadron particles.

The Only Radiation Units You Need to Know
In order to have a meaningful conversation about the dangers of radiation exposure, it’s important to be clear about just how much radiation we are dealing with. Unfortunately, the units we use are kind of a mess… but SciShow is here...

Conservation of Electric Charge
In this video Paul Andersen explains how the conservation of charge applies to objects in a system. When a charged object induces charge or conducts charge to a neutral object the net total of charge will not change. Grounding allows...

Nuclear Reactions
Mr. Andersen contrasts nuclear reactions to chemical reactions. He explains the four main forces of nature; including gravity, electromagnetism, strong, and weak nuclear forces. He also explains how fusion differs from fission.

Elementary Charge
In this video Paul Andersen explains how electric charge is quantized and how the smallest unit of charge is 1.6x10^-19 C, or the elementary charge. Robert Millikan discovered the elementary charge using the oil drop experiment....
