I came across Physicist Michio Kaku when I used a quote in a blog, Goodbye Stephen!
“Not since Albert Einstein has a scientist so captured the public imagination and endeared himself to tens of millions of people around the world,”
His, The Universe in a Nutshell presentation is a must watch. You may have to force yourself. But I think in the end, it'll be worth it. I learnt more about the history of physics in 40 minutes than I had throughout my life. Wish this was the complete physics course. It covers more. :)
