The growth of technology is such that it is not possible today for a nuclear physicist to switch into medical physics without training. The field is now much more technical. More training is needed to do the job.

When I entered medical physics in 1958 there were fewer than 100 in the U.S. and I could see many opportunities to apply my knowledge of nuclear physics.

The object of pure physics is the unfolding of the laws of the intelligible world the object of pure mathematics that of unfolding the laws of human intelligence.

To regard the imagination as metaphysics is to think of it as part of life and to think of it as part of life is to realize the extent of artifice. We live in the mind.

You will certainly not doubt the necessity of studying astronomy and physics if you are desirous of comprehending the relation between the world and Providence as it is in reality and not according to imagination.

They can shout down the head of the physics department at Cal Tech.

My father was on the faculty in the Chemistry Department of Harvard University my mother had one year of graduate work in physics before her marriage.

I received my undergraduate degree in engineering in 1939 and a Master of Science degree in mathematical physics in 1941 at Steven Institute of Technology.

A universe with a God would look quite different from a universe without one. A physics a biology where there is a God is bound to look different. So the most basic claims of religion are scientific. Religion is a scientific theory.

It is funny that men who are supposed to be scientific cannot get themselves to realise the basic principle of physics that action and reaction are equal and opposite that when you persecute people you always rouse them to be strong and stronger.

Metaphysics is a restaurant where they give you a thirty thousand page menu and no food.

The kitchen's a laboratory and everything that happens there has to do with science. It's biology chemistry physics. Yes there's history. Yes there's artistry. Yes to all of that. But what happened there what actually happens to the food is all science.

For more than 200 years materialists have promised that science will eventually explain everything in terms of physics and chemistry. Believers are sustained by the faith that scientific discoveries will justify their beliefs.

If I want to understand the laws of physics I have to first believe what I read about physics. I have to have faith in what I read.

Physics is experience arranged in economical order.

As for the forces electromagnetism and gravity we experience in everyday life. But the weak and strong forces are beyond our ordinary experience. So in physics lots of the basic building blocks take 20th- or perhaps 21st-century equipment to explore.

Physics does not change the nature of the world it studies and no science of behavior can change the essential nature of man even though both sciences yield technologies with a vast power to manipulate the subject matters.

Most people have no concept of how an automatic transmission works yet they know how to drive a car. You don't have to study physics to understand the laws of motion to drive a car. You don't have to understand any of this stuff to use Macintosh.

I like physics. I think it is the best science out of all three of them because generally it's more useful. You learn about speed and velocity and time and that's all clever stuff.

That attitude does not exist so much today but in those days there was a very sharp distinction between basic physics and applied physics. Columbia did not deal with applied physics.

You watch an old 'Jeopardy!' and the categories alone are very plain. 'Poetry ' or 'Movies ' or 'Physics.' If you watch it now though there'll be a theme board where the categories are all Hitchcock movies. Lots more jokes lots more high-concept categories and questions.

We were making the first step out of the age of chemistry and physics and into the age of biology.
