Crash Course: Chemistry

Hank does his best to convince us that chemistry is not torture, but is instead the amazing and beautiful science of stuff.

Chemistry can tell us how three tiny particles - the proton, neutron and electron - come together in trillions of combinations to form... everything.

We start out with one of the biggest ideas in chemistry ever - stuff is made from atoms. More specifically, we learn about the properties of the nucleus and why they are important to defining what an atom actually is.

A unit is the frequently arbitrary designation we have given to something to convey a definite magnitude of a physical quantity and every quantity can be expressed in terms of the seven base units that are contained in the international system of units.

Hank thinks this is a thrilling subject, and while you may not agree, it is a subject that is very important if you want to be a scientist and communicate with accuracy and precision with other scientists.
