I'm a physicist and computer scientist by training. I worked in high tech for thirty years as everything from engineer to senior vice president - for many of those years, writing SF as a hobby - until, in 2004, I began writing full time.

Edward M. Lerner

Energy is a concept that has been coined by physicists. There is no observable thing known as energy anywhere.

Abdolkarim Soroush

The development of quantum mechanics early in the twentieth century obliged physicists to change radically the concepts they used to describe the world.

Alain Aspect

Every physicist knows that things connect with each other. To isolate things is not the way the universe works - winning best actor is arbitrary.

Alan Arkin

To a theoretical physicist, there is no greater joy than to see that this curious activity we call calculation - the depositing of ink on paper, followed by throwing away the paper and depositing new ink on more paper - can actually tell us something about reality.

Alan Guth

Now, what space ultimately is - I should confess, I think most physicists believe - we don't yet know.

Alan Guth

I started out as a physicist; however, I am what I have become. I have evolved, with the help of many colleagues in the international scientific community, into an interdisciplinary scientist.

Alan J. Heeger

Whether you are an astronomer or a life scientist, geophysicist, or a pilot, you've got to be there because you believe you are good in your field, and you can contribute, not because you are going to get a lot of fame or whatever when you get back.

Alan Shepard

If I were not a physicist, I would probably be a musician. I often think in music. I live my daydreams in music. I see my life in terms of music.

Albert Einstein

My dad's a biophysicist. My brother is a computer guy. His wife works at Microsoft.

Alec Berg

Rush Holt would be a fine senator. He's an actual physicist, which is neat. He cares very strongly about global warming, which is probably the single most pressing issue of our era.

Alex Pareene

We should note that this latter type of shift was successfully amplified to a considerable extent by Russian physicists using the intense light of a ruby laser whose wavelength is close to that of a transition of the potassium atom.

Alfred Kastler

Black holes are very exotic objects. Technically, a black hole puts a huge amount of mass inside of zero volume. So our understanding of the center of black holes doesn't make sense, which is a big clue to physicists that we don't have our physics quite right.

Andrea M. Ghez

My mom is an experimental chemist and physicist, so she is a cut-and-dried, nuts-and-bolts kind of woman, and my dad is a theoretical chemist, so we were definitely raised with his philosophical point of view: imaginary numbers and dimensions beyond our own. That's the kind of thing we would talk about.

Andrew Sean Greer

There are no excuses for theoretical physicists not to perform and deliver.

Ashoke Sen

Physicists explain creation by telling us that the universe began with the Big Bang, an intense energy singularity that continued expanding. But who created the singularity?

Ashwin Sanghi

It's hard to do large, expensive projects without some sort of hierarchical structure where somebody can tell you - maybe softly, but at least tell you - what to do, or you have some supervision over you. Physicists like to be completely independent of each other. So that's a constant struggle. And it's a place that sometimes we get in trouble.

Barry Barish

I always wanted to be an experimental physicist and was attracted to the idea of using continuing advances in technology to carry out fundamental science experiments that could not be done otherwise.

Barry Barish

Anything that makes us take more seriously scientists - or economists or chemists or physicists or biologists - I think is helpful in times when things get distorted because of people not paying attention to all the facts.

Barry Barish

Scientists, especially physicists, we're presumptuous and think we can do everything better than everybody else. And one thing that I realized early is, I had some talent managing and organizing things - you know, some people are better organizers than others - but why should I reinvent the wheel?

Barry Barish

The weapons were conceived and created by a small band of physicists and chemists; they remain a cataclysmic threat to the whole of human society and the natural environment.
