In the evenings I studied chemistry at the University of Chicago, the weekends I helped in the family store.

I reverted easily to my wild state, that is experimentation.

In 1934, the American Jewish charities offered to find homes for 300 German refugee children. We were on the SS Washington, bound for New York, Christmas 1934.

I studied chemical engineering. I was a good student, but these were the hard times of the depression, my scholarship came to an end, and it was necessary to work to supplement the family income.

I had no new ideas on the physics we might learn, and I could not compete with the younger generation.

I'm now a bit anti-Jewish since my last visit to the synagogue, but my atheism does not necessarily reject religion.

The problem of transmitting scientific knowledge is a very difficult business.
