Hank Green has launched a new Crash Course series on YouTube. His new series is all about psychology. The first video was released yesterday and it has already been viewed more than 100,000 times.

Crash Course Psychology follows the same fast-paced format as the other Crash Course videos. The first installment offers an overview of what psychology is and some of the base concepts and their contributors to the field of psychology. Like other Crash Course videos you would have to watch it multiple times to catch everything offered in it. That said, as an overview for review or introduction it’s fine.
