Quotes About Physics

By allowing the positive ions to pass through an electric field and thus giving them a certain velocity, it is possible to distinguish them from the neutral, stationary atoms.

The grounding in natural sciences which I obtained in the course of my medical studies, including preliminary examinations in botany, zoology, physics, and chemistry, was to become decisive in determining the trend of my literary work.

Spacetime tells matter how to move; matter tells spacetime how to curve.

Spacetime grips mass, telling it how to move... Mass grips spacetime, telling it how to curve

Recent decades have taught us that physics is a magic window. It shows us the illusion that lies behind reality—and the reality that lies behind illusion. Its scope is immensely greater than we one realized. We are no longer satisfied with insights only into particles, or fields of force, or geometry, or even space and time. Today we demand of physics some understanding of existence itself.

Physicists love this number not just because it is dimensionless, but also because it is a combination of three fundamental constants of nature. Why do these constants come together to make the particular number 1/137.036 and not some other number?

My background is basically scientific math. My Dad was a physicist, so I have it in my blood somewhere. Scientific method is very important to me. I think anything that contradicts it is probably not true.

Bohr was inconsistent, unclear, wilfully obscure and right. Einstein was consistent, clear, down-to-earth and wrong.

Can it be that all of physics—and, indeed, all of science—is based on creating all the matter in the universe from a dozen objects with totally random mass values, while no one has the faintest idea about their origin?

Since string theorists have failed to propose any way to confirm string theory experimentally, string theory should be retired

When Max Planck began studying physics at the University of Munich in 1874, his teacher, Philipp von Jolly, warned him that it was already a mature field, with little more to learn.

In 1900, Lord Kelvin, the great British physicist, put it clearly: "There is nothing new to be discovered in physics now. All that remains is more and more precise measurement.

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 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.

Medical physics is an applied area of physics.

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.

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

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

We have never explained the numerical value of any of the constants of Nature.

Already we see a trend in our own technological societies towards the fabrication of smaller and smaller machines that consume less and less energy and produce almost no waste. Taken to its logical conclusion, we expect advanced life-forms to be as small as the laws of physics allow.

Each of us is a complicated assymetrical outcome of the laws of electromagnetism and gravity.

A 4'33 összesen 273 másodpercet jelent, amire a fizikus rögtön felkapja a fejét. A -273 Celsius-fok az abszolút nulla hÅ'mérsékletet jelenti. Ez az az energiaszint, ahol megsz?nik minden molekuláris mozgás, ami azt is jelenti, hogy ezt a hÅ'mérsékletet már nem lehet tovább csökkenteni. Cage e m?vével a hang abszolút nullpontját kívánta megmutatni.

Particle physicists are the most deeply Platonic because their entire subject is built upon a belief that the deepest workings of the world are based upon symmetries. They examine symmetry after symmetry, confident in the expectation that the biggest and the best will have found employ in the grand scheme of things.

It is the cosmological vacuum energy that contributes a repulsive lambda force to the gravitational force of Newton.
