Introduction to the art of lighting.
Binary fission, budding, mitosis, fragmentation, parthenogenesis and sexual reproduction.
In this video, David explains how an atom can absorb and emit photons with particular values of energy and how to determine the allowed values.
The difference between atomic weight and atomic mass in chemistry, and how it compares to the physics definitions of weight and mass.
Chemistry is the study of matter, and all matter is made up of atoms. We will learn about elements, atomic number and mass, isotopes, moles (chemistry moles, not the animal), and compounds.

Sal solves a word problem to find average velocity and speed of an object in one-dimension.
David explains how a mass can have angular momentum even if it is traveling along a straight line. Then David shows how to solve the conservation of angular momentum problem where a ball hits a rod which can rotate. Created by David SantoPietro.
Overview of basic shot types.
