Chen-Ning Yang Quotes

Today's particle physics describe light as a crumple in space, and we may have deformed space in such a way that they noticed something peculiar - and they had the ability to investigate it.

Quantum field theory was originally developed for the treatment of electrodynamics, immediately after the completion of quantum mechanics and the discovery of the Dirac equation.

Since Einstein developed his theory of relativity, and Rutherford and Bohr revolutionised physics, our picture of the world has radically changed.

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.

The biggest conceptual change over the last 100 years in the way physicists think about the world is symmetry.

We have to have a combination of general relativity that describes the warping of space and time, and quantum physics, which describes the uncertainties in that warping and how they change.

So what I'm saying is why don't we think about changing Schrodinger's equation at some level when masses become too big at the level that you might have to worry about Einstein's general relativity.

The problem is that replacement of Quantum Mechanics by Quantum Field Theory is still very demanding.

The math of quantum mechanics and the math of general relativity, when they confront one another, they are ferocious antagonists and the equations don't work.

Einstein's theory of relativity does a fantastic job for explaining big things. Quantum mechanics is fantastic for the other end of the spectrum - for small things.

Among the questions we have in mind: dark matter, antimatter, and matter symmetry.

The whole edifice of modern physics is built up on the fundamental hypothesis of the atomic or molecular constitution of matter.

I had set out to disprove quantum field theory - and the opposite occurred! I was shocked.

I get paid to do what I love. If you understand physics, the foundation of the atomic theory and relativity, you understand how the future is going to unfold. You understand what things are not possible. You understand why things work. I get paid to do what I love the most, and that is to work on the Unified Field Theory and to see the future.

The mathematics of quantum mechanics very accurately describes how our universe works.

I like to call it the scalar boson because this reflects an essential component of the theory - it means that the field the boson travels through has no preferred direction, unlike the way a magnetic field does.

Quantum physics is a bit of a passion of mine. It's extraordinary. There's a branch of mathematics that is based on lunacy, and that's wonderful.

I am fascinated by quantum physics.

In string theory, all particles are vibrations on a tiny rubber band; physics is the harmonies on the string; chemistry is the melodies we play on vibrating strings; the universe is a symphony of strings, and the 'Mind of God' is cosmic music resonating in 11-dimensional hyperspace.

While at Chicago my interest in the new field of particle physics was stimulated by a course given by Gell- Mann, who was developing his ideas about Strangeness at the time.

With the exception of gravitation and radioactivity, all of the phenomena known to physicists and chemists in 1911 have their ultimate explanation in the laws of quantum electrodynamics.

Ultimately, my Ph.D. is in mathematical physics, focusing on quantum field theory and curved space-time, and I worked with Stephen Hawking.

From a consideration of the immense volume of newly discovered facts in the field of physics, especially atomic physics, in recent years it might well appear to the layman that the main problems were already solved and that only more detailed work was necessary.

You have that one basic string, but it can vibrate in many ways. But we're trying to get a lot of particles because experimental physicists have discovered a lot of particles.

It's indeed surprising that replacing the elementary particle with a string leads to such a big change in things. I'm tempted to say that it has to do with the fuzziness it introduces.
