I just watched the whole episode. I see again why I liked it so much 47 years ago. Going to start at the beginning and watch the series.
Bronowski was a contemporary of John von Neumann.
en.wikipedia.org
Bronowski tells the story in one episode that von Neuman was the most brilliant person he ever met and an anecdote. Von Neuman and someone, may have been Bronowski, were discussing something late into the night. von Neuman was known to stay up very, very late and wake very late. The person called von Neuman in the morning to say that von Neuman was right about what they were discussing.
"You wake me up early in the morning to tell me that I'm right? Please wait until I'm wrong."
John von Neumann
