Tolle Lege!.

The choice is yours. You can let the popular media and the Mystics continue to tell you that particles physics is woo and mysticism or you can listen to this highly accessible lecture and realize what particle physics is all about and learn why neutrinos are so important, what c-p violation means, and what makes up the universe at the most fundamental level.

The lecturer doesn't tell you anything without first telling you the context and how we know what we know. I still don't understand what a photon really is or what exactly is meant by spin, but that's not the fault of the lecture. It's more that their real meaning is tied up with esoteric mathematics and the lecture stays away from the math.
