Robert Jay Lifton – Genocidal Mentality: Nazi Doctors and the Holocaust

The video is somewhat funky (video flashes), but the audio is fine, though slightly out of sync. The embedded version skips the introduction.

Lifton’s book, The Nazi Doctors: Medical Killing and the Psychology of Genocide can be found on-line to read.

Riding Light

In our terrestrial view of things, the speed of light seems incredibly fast. But as soon as you view it against the vast distances of the universe, it’s unfortunately very slow. This animation illustrates, in realtime, the journey of a photon of light emitted from the surface of the sun and traveling across a portion of the solar system, from a human perspective.

I’ve taken liberties with certain things like the alignment of planets and asteroids, as well as ignoring the laws of relativity concerning what a photon actually “sees” or how time is experienced at the speed of light, but overall I’ve kept the size and distances of all the objects as accurate as possible. I also decided to end the animation just past Jupiter as I wanted to keep the running length below an hour.
