I was surprised that Einstein's video and voice was preserved when I first saw him in a video. It never occurred to me to go out and check for such videos even though everyone holds him in high regard. This is also similar to the fact that I didn't know the top five contributions of Edward Witten, even though everyone considers him to our current generation Einstein. Only when I saw a video on that topic that I realized my folly, I should have sought such information actively. So much of our beliefs are formed through some kind of osmosis from the air. What works did Edward Witten do? https://www.youtube.com/watch?v=8xDSVeiVxMI https://www.youtube.com/watch?v=8xDSVeiVxMI
