About seven years later I was given a book about the periodic table of the elements. For the first time I saw the elegance of scientific theory and its predictive power.

I was born in Montreal in 1939, the second son of poor immigrants.

Eight months later, having left Columbia, I was studying physics in a summer program and working in Colorado when I decided to enroll as a graduate student in biophysics.

My intention was to enroll at McGill University but an unexpected series of events led me to study physics at the Massachusetts Institute of Technology.

For our immediate family and relatives, Canada was a land of opportunity.

I spent eighteen months as a graduate student in physics at Columbia University, waiting unhappily for an opportunity to work in a laboratory and wondering if I should continue in physics.
