Walter Lewin: The Physics Crackerjack!

The most dangerous demonstration in my opinion!

A tall, lanky figure, with an Albert Einstein like hairstyle, you would probably think he has been taken right out of a sci-fi horror movie. Especially after he starts his demonstrations, you would start questioning his sanity. At 76, he is a well known figure in cyber space for his video lectures. Possibly the only three courses which keep MIT Open Course Ware running, this guy is one who truly loves Physics.
