All of science can be divided into physics and stamp-collecting.

All the standard equations of mathematical physics can be separated and solved in Kerr geometry.

A lot of my theories were not applicable as a closer

A scenario is suggested by which the universe and its laws could have arisen naturally from nothing. Current cosmology suggests that no laws of physics were violated in bringing the universe into existence. The laws of physics themselves are shown to correspond to what one would expect if the universe appeared from nothing. There is something rather than nothing because something is more stable.

As an undergraduate, I did maths and physics. That doesn't make me a scientist. So I try to read and understand and talk to scientists.

As physics is a mental reconstruction of material processes, perhaps a physical reconstruction of psychic processes is possible in nature itself.

But even physics cannot be defined from an atomic topography.

Cambridge was the place for someone from the Colonies or the Dominions to go on to, and it was to the Cavendish Laboratory that one went to do physics.

Don't be surprised if in the 21st century lectures on meditation appear in university catalogues for physics.

Digital mechanics predicts that for every continuous symmetry of physics there will be some microscopic process that violates that symmetry.

Classical physics has been superseded by quantum theory: quantum theory is verified by experiments. Experiments must be described in terms of classical physics.

[Computer science] is not really about computers and it's not about computers in the same sense that physics is not really about particle accelerators, and biology is not about microscopes and Petri dishes... and geometry isn't really about using surveying instruments.

Even before string theory, especially as physics developed in the 20th century, it turned out that the equations that really work in describing nature with the most generality and the greatest simplicity are very elegant and subtle.

Don't waste your time on beaming people up or down. Instead, consider gravity waves as advanced physics of the universe that could be used to travel interstellar distances.

Engineering is merely the slow younger brother of physics.

Ever since I was a kid, I've had an enormous interest in the sciences - everything from quantum physics to anthropology.

Everything is energy. It's physics. So I find the science of it all interesting; how 90% of stuff that's in our universe is made of stuff that we can't even measure. I find that fascinating.

For me, [John Wheeler] was the last Titan, the only physics superhero still standing.

Everything we call real is made of things that cannot be regarded as real.

Hard to be a physics major at Rice University if you have flunked calculus.

Going to the moon is not a matter of physics but of economics.

I don't. We've had three technological revolutions that have changed the course of human history, all driven by physics. In the first, the industrial revolution, physicists developed Newtonian mechanics and thermodynamics, which gave us the steam engine and machine power. The second technological revolution was the electricity revolution. That gave us radio, television, and telecommunications. Then, physicists developed the laser and the transistor.

[Heisenberg's seminal 1925 paper initiating quantum mechanics marked] one of the great jumps—perhaps the greatest—in the development of twentieth century physics.

I am fascinated by quantum physics.

I am now convinced that theoretical physics is actually philosophy.

I began peering into the corners of the room, making sure all the shadows were cast by objects and obeying known laws of physics.

I do find that Western medicine is more and more open to proving energetic concepts. Why not, because modern physics is 100 percent based on it.

How can you be a physics major and be shocked when you get pregnant from having sex?

If I can't picture it, I can't understand it.

I entered the Physics Department in 1950, receiving a Master's degree in 1953 and a Ph.D. in 1956. It is difficult to convey the sense of excitement that pervaded the Department at that time.

If someone says that he can think or talk about quantum physics without becoming dizzy, that shows only that he has not understood anything whatever about it.

If it weren’t for physics and law enforcement, I’d be unstoppable.

I got into physics through pop science and quantum science and ended up being such a quantum groupie.

If the laws of physics be for us, who can be against us?!

I have always believed that astrophysics should be the extrapolation of laboratory physics, that we must begin from the present universe and work our way backward to progressively more remote and uncertain epochs.

I had no new ideas on the physics we might learn, and I could not compete with the younger generation.

I have sold more books on physics than Madonna has on sex. [Hawking adopted this statement from a remark made to him by his former post-doc, Nathan Myhrvold.]

I just really like ants, and I really like science. I was interested and curious about the quantum world and the physics behind how it all works.

I like to think the moon is there even if I am not looking at it.

I may have made a straight A in physics, but I was panic-struck. Physics made me sick the whole time I learned it.

I'm a bit of a layman physics junkie. I don't really understand it, but I love trying to understand it.

I make figurative portraits as a way to explore theories of quantum physics.

I'm fascinated with quantum physics.

In 1948 I was appointed to a Lectureship in Physics and in 1949 elected to a Fellowship at Trinity College.

In geometric and physical applications, it always turns out that a quantity is characterized not only by its tensor order, but also by symmetry.

In a previous life I wrote the software that controlled my physics experiments. That software had to deal with all kinds of possible failures in equipment. That is probably where I learned to rely on multiple safety nets inside and around my systems.

In Einstein's theory of relativity the observer is a man who sets out in quest of truth armed with a measuring-rod. In quantum theory he sets out with a sieve.

In the 20th century philosophy of time for a great many theorists became part of science because it was time as is studied in physics that became the object of philosophical speculation. That's very different from the way time has normally been understood.

In physics, your solution should convince a reasonable person. In math, you have to convince a person who's trying to make trouble. Ultimately, in physics, you're hoping to convince Nature. And I've found Nature to be pretty reasonable.

Instead of physicists teaching physics, physicists should go home and see what physics applies to their home.
