Many Nobel Prizes are awaiting good research to understand and explain the many mysteries of our bodies, such as the basic mechanism of memory or imagination.

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.

I have the satisfaction of knowing I did something useful for society.

Most medical physicists work in the physics of radiation oncology making sure that the desired dose is given to the cancer and the dose to normal tissues are minimized.

When I entered the field in July 1958 I believed what they told me about radiation risks. I spent much effort reducing the dose to patients in radiology.

Medical physicists work in cooperation with doctors. A few medical physicists devote their time to research and teaching. A few get involved with administrative duties.

Too many radiologists still believe there is a risk from a chest x-ray. Few radiologists can explain radiation to the patient in words the patient can understand.

I am now almost certain that we need more radiation for better health.

I was the Chair of the first department of medical physics in a medical school in the U.S.

There are now over 5,000 medical physicists in the U.S more than 50 times the number in 1958.

Many Nobel Prizes are awaiting good research to understand and explain the many mysteries of our bodies, such as the basic mechanism of memory or imagination.

In 1970 I realized that there was negligible risk from x-rays but many radiographs had poor image quality so that the risk from a false negative was significant.

I would not encourage everyone to take up this profession. Not everyone is suited for any particular field.

We developed simple test tools to optimize imaging parameters. No company was interested in our idea.

If someone is interested in medicine and also in physics and they like working with people and communicate well with others, I would strongly encourage them.

I have devoted much time and energy to helping medical physics in developing countries.

I am sure that I have been much more useful to society as a medical physicist.

In some cases radiation reduces the incidence of cancer.

I am not unhappy that my contribution was not recognized. I am sure it helped my career.

I don't display my plaques and honors. They are hidden behind a black curtain in my work room at home.

Nuclear physics is interesting but it is unlikely to help society.

Medical physics is an applied area of physics.

I found collaborating with congenial doctors about problems that physicists could help solve was very satisfying. I also like educating anybody who would listen!

It is likely that we need more radiation to improve our longevity.

My main frustration is the fear of cancer from low dose radiation, even by radiologists.

I started the nuclear medicine laboratory at UW Hospitals in 1959 and trained radiology residents in the field. It was 1965 before they found a trained MD (doctor) to take over my role.

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.

Logic will get you from A to B. Imagination will take you everywhere.

For someone who writes fiction, in order to activate the imagination and the unconscious, it's essential to be free.

The most dire disaster in love is the death of imagination.

We especially need imagination in science.

There is only one admirable form of the imagination: the imagination that is so intense that it creates a new reality, that it makes things happen.

He is indebted to his memory for his jests and to his imagination for his facts.

It takes a lot of imagination to be a good photographer. You need less imagination to be a painter because you can invent things. But in photography everything is so ordinary; it takes a lot of looking before you learn to see the extraordinary.

Politics is the enemy of the imagination.

Happiness is ideal, it is the work of the imagination.

Memories, imagination, old sentiments, and associations are more readily reached through the sense of smell than through any other channel.

You want to do something that shows some type individuality and talent and imagination - at the same time, you want to be truthful to the predecessors, because obviously the audience liked something about them and you have to replicate that experience to a certain extent.

To them though, not to us, we were just a catalyst for their imagination.

In this drawing we just let our imagination run wild. We visualized Superman toys, games, and a radio show - that was before TV - and Superman movies. We even visualized Superman billboards. And it's all come true.

To put yourself in another's place requires real imagination, but by doing so each Girl Scout will be able to love among others happily.

If you use your imagination, you can look at any actress and see her nude... I hope to make you use your imagination.

Toy Soldiers was my introduction to film. I certainly didn't think I was doing art by any stretch of the imagination.

There is hope in dreams, imagination, and in the courage of those who wish to make those dreams a reality.

The worlds I paint leave a lot to engage the imagination by hinting at what lies beyond the four edges of the painting. I think getting beyond the four edges of an opportunity or challenge is one of the basic skills you need in business.

Intelligence is the wife, imagination is the mistress, memory is the servant.

The travel writer seeks the world we have lost - the lost valleys of the imagination.

The past is really almost as much a work of the imagination as the future.

Enthusiasm is that temper of the mind in which the imagination has got the better of the judgment.
