This is Scientific Americans' 60-second science. I'm Steve Merski. Got a minute?

There's a lot of discussion about the debates they had and who was right.

Wilhelm Bohr, he's the grandson of the great physicist Niels Bohr, who had strong scientific disagreements with Albert Einstein.

For example, Einstein was uncomfortable with

the probabilistic nature of aspects of quantum mechanics, which Bohr accepted. But they did have a very

warm relationship. On June 3, 2015, Wilhelm Bohr talked about his famous grandfather at length

in a public lecture at the Perimeter Institute for Theoretical Physics in

Waterloo, Ontario, Canada. I just found these two letters here that I thought would be interesting

to just highlight. So they received the Nobel Prize the same year in 1922, and that was because

Einstein's Nobel Prize was delayed because of the war.

Nilsbore was writing to Einstein how deeply honored he is to get the Nobel Prize at the same time.

I'm sending my warmest congratulations on the occasions of you receiving a Nobel Prize.
