Feynman — The Relation of Physics to Other Sciences Dec 2023

Just two out of so many wonderful lectures

The Relation of Physics to Other Sciences

Given October 3, 1961
Lecture #3

Exciting stuff

The Value of Science

Given at the 1955 autumn meeting of the National Academy of Sciences

A sober lecture


To every man is given the key to the gates of heaven; the same key opens the gates of hell.

When we read about this in the newspaper, it says “Scientists say this discovery may have importance in the search for a cure for cancer.” The paper is only interested in the use of the idea, not the idea itself. Hardly anyone can understand the importance of an idea, it is so remarkable. Except that, possibly, some children catch on. And when a child catches on to an idea like that, we have a scientist. It is too late for them to get the spirit when they are in our universities, so we must attempt to explain these ideas to children.
