The discovery of superfluidity opened up a new understanding in the science world.

Modern low temperature physics began with the liquefaction of helium by Kamerlingh Onnes and the discovery of superconductivity at the University of Leiden in the early part of the 20th century.

There are few moments in science in which you genuinely are excited. The discovery of superfluidity in helium-3 was one of those moments.

Following graduation from high school in 1948, I attended Harvard University where I became a physics major. Having grown up in a small town, I found Harvard to be an enormously enriching experience. Students in my class came from all walks of life and from a great variety of geographical locations.

My first undertaking in the way of scientific experiment was in the field of economics and psychology.

I've danced one time in my life. It was the most mortifying experience I ever had.

I am fascinated by the engineering. The science of constructing and understanding why it stands. And I am drawn by the madness, the beauty, the theatricality, the poetry and soul of the wire. And you cannot be a wire-walker without mingling those two ways of seeing life.

I took Laura on a trip once where we followed the Immigrant Trail for about six hundred miles. She really learned a lesson. People forget too often how it was back then.
