When learning about a new topic, I often look for content that is brief, visual, and summarized by experts. This is why TED Talks are so sweet. Experts walk up on the stage to summarize their life's work in ten to fifteen minutes with engaging slides.
Recently I came across a series of video lectures that capture these three elements. It is called Minute Physics. On this YouTube channel Henry Reich publishes quick, animated videos about cool physics topics such as how lasers work or cosmic theories of the universe. Reich does a great job explaining these complex topics clearly and enjoyably. Good news is Reich is developing new content in partnership with other authors called Minute Earth.
