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

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

I look back upon graduate school as being a very happy period in my life. The chance to be thoroughly immersed in physics and to be surrounded by friends pursuing similar goals was a marvelous experience.

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.

I think what's always been interesting to me than the science and the criminality with this job is what happens to your persona, your disposition, after day in and day out dealing with life and death.

Science ignores the spiritual realm because it is not amenable to scientific analysis. As importantly, the predictive success of Newtonian theory, emphasizing the primacy of a physical Universe, made the existence of spirit and God an extraneous hypothesis that offered no explanatory principles needed by science.

One of the bedrock principles of physics is the conservation of energy. In this universe, energy can be neither created nor destroyed.

Science in textbooks is not fun. But if you start doing science yourself, you will find delight.
