My parents regarded school teachers as higher beings, as did many immigrants.

My final remark to young women and men going into experimental science is that they should pay little attention to the speculative physics ideas of my generation. After all, if my generation has any really good speculative ideas, we will be carrying these ideas out ourselves.

My parents were determined to move into the middle class.

I read everything: fiction, history, science, mathematics, biography, travel.

Going to school and working for good marks, indeed working for very good marks, was a serious business.

They wanted me to play more sports because they were acutely sensitive to their children being one hundred percent American, and they believed that all Americans played sports and loved sports.

The remoteness of my parents from the schools, so unfashionable today, was often painful for me, but I learned early to deal with an outside and sometimes hard world.

About 1900 my parents came to the United States as children from what was then the Polish area of Russia.

Experimental science is a craft and an art, and part of the art is knowing when to end a fruitless experiment. There is a danger of becoming obsessed with a fruitless experiment even if it goes nowhere.

Whatever the course, whether the course was boring or interesting to me, whether I was talented in mathematics or not talented in languages, my parents expected A's.

It was good fortune to be a child during the Depression years and a youth during the war years.

Their educations ended with high school - my father going to work as a clerk and then salesman in a company dealing in printing and stationary, and my mother working as a secretary and then bookkeeper in a firm of wool merchants.

I learned quickly, as I tell my graduate students now, there are no answers in the back of the book when the equipment doesn't work or the measurements look strange.
