Here's something to consider:
-
In an address to Caltech students, he talked about how: ...science had not been been harnessed to do more good than harm. During war it gave people "the means to poison and mutilate each other", and in peacetime "it has made our lives hurried and uncertain". Instead of being a liberating force "it has enslaved men to machines" by making them work "long wearisome hours without joy in their labor". Concern for making life better for humans must be the chief object of science. "Never forget this when you are pondering over your diagrams and equations".
Can you guess who gave that speech? Hint, he was the
Time Person of the 20th Century. Quoted from
page 374 of this biography.
Time for a little break.
