Quotes About Physics

It would seem that I, who never could make much sense of physics when I was at school, have now gained a strong sense of Einsteinian space-time. I am free of the nimbyism of now, and feel a strong kinship with both the dead and the unborn.

Science seems to be at war with itself.... Naive realism leads to physics, and physics, if true, shows naive realism to be false. Therefore naive realism, if true, is false; therefore it is false.

Physics admits of a lovely unification, not just at the level of fundamental forces, but when considering its extent and implications. Classifications like "optics" or "thermodynamics" are just straitjackets, preventing physicists from seeing countless intersections.

There have always been arguments showing that free will is an illusion, some based on hard physics, others based on pure logic. Most people agree these arguments are irrefutable, but no one ever really accepts the conclusion. The experience of having free will is too powerful for an argument to overrule.

Most people agree these arguments are irrefutable, but no one ever really accepts the conclusion. The experience of having free will is too powerful for an argument to overrule. What it takes is a demonstration, and that's what a Predictor provides.

Physical law is what makes it possible to study the past; examine the state of the universe closely enough, and we can infer its state a moment earlier in time.

My background is in physics, so I was the mission specialist, who is sort of like the flight engineer on an airplane.

For a physicist or a mathematician, the most symmetrical object you could think about would be a sphere, because it looks identical no matter what you do to it, however you rotate it in any given direction.

Relativity must replace absolutism in the realm of morals as well as in the spheres of physics and biology.

Ordinary photons do have spin, they have a notion of helicity so they spin around their direction on motion.

Quantum field theory, which was born just fifty years ago from the marriage of quantum mechanics with relativity, is a beautiful but not very robust child.

I am acutely aware of the fact that the marriage between mathematics and physics, which was so enormously fruitful in past centuries, has recently ended in divorce.

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.

What one man calls God, another calls the laws of physics.

Understanding how DNA transmits all it knows about cancer, physics, dreaming and love will keep man searching for some time.

There is a remarkably close parallel between the problems of the physicist and those of the cryptographer. The system on which a message is enciphered corresponds to the laws of the universe, the intercepted messages to the evidence available, the keys for a day or a message to important constants which have to be determined. The correspondence is very close, but the subject matter of cryptography is very easily dealt with by discrete machinery, physics not so easily." —Alan Turing

enhanced the physics of The Black Sun to make it a little cartoonish, so that particularly obnoxious people can be hit over the head with giant mallets or crushed under plummeting safes before they are ejected.

As far as the laws of probability, my lady, these cannot be broken, any more than any other mathematical principle. But laws of physics and mathematics are like a coordinate system that runs in only one dimension. Perhaps there is another dimension perpendicular to it, invisible to those laws of physics, describing the same things with different rules, and those rules are written in our hearts, in a deep place where we cannot go and read them except in our dreams.

in the informal atmosphere of the Physics Department, appointments were viewed with a certain Heisenbergian skepticism, as though being in the right place at the right time would involve breaking a natural law and was therefore impossible to begin with.

The power and beauty of physical laws is that they apply everywhere, whether or not you choose to believe in them. In other words, after the laws of physics, everything else is opinion.

The remarkable feature of physical laws is that they apply everywhere, whether or not you choose to believe in them. After the laws of physics, everything else is opinion.

Matter tells space how to curve; space tells matter how to move.?
