and his biology, he gets from pondering... Khan on Entropy: In a recent talk he explained how he prepared for his lecture on entropy: "I took two weeks off and I just pondered it, and I called every professor and everyone I could talk to and I said, Let's go have a glass of wine about entropy." I'm sure you realise that entropy is not a concept from biology, but it isn't clear from your comment. Since he has a background in engineering, and therefore a reasonable physics and chemistry grounding, I would guess that he had his "glasses of wine" and pondering to make sure he covered all the bases, and thought of a helpful way of explaining it. Have you watched his lectures on entropy? Is there anything wrong with them? I'm sure constructive criticism is better than calling him names and picking on his research methods.
