A Quote by David Gross
When I was at Berkeley, the framework of quantum field theory could calculate the dynamics of electromagnetism. It could roughly describe the motion of the weak nuclear force, radiation. But it hit a brick wall with the strong interaction, the binding force.

In the lab, we could not see or physically describe the mathematical objects that we called quarks, which we suspected were the key to unlocking the dynamics of the strong force that binds together the clump of protons and neutrons at the center of the atom.
Force, force, everywhere force; we ourselves a mysterious force in the centre of that. "There is not a leaf rotting on the highway but has Force in it: how else could it rot?" [As used in his time, by the word force, Carlyle means energy.]
What lead me more or less directly to the special theory of relativity was the conviction that the electromotive force acting on a body in motion in a magnetic field was nothing else but an electric field.
I think its one of the great principles. The element of surprise, I mean, you could take a force that's not nearly as strong and with the element of surprise you could wipe out a much more powerful force.
Because the theory of quantum mechanics could explain all of chemistry and the various properties of substances, it was a tremendous success. But still there was the problem of the interaction of light and matter.
Quantum field theory arose out of our need to describe the ephemeral nature of life.
The libertarian approach is a very symmetrical one: the non-aggression principle does not rule out force, but only the initiation of force. In other words, you are permitted to use force only in response to some else's use of force. If they do not use force you may not use force yourself. There is a symmetry here: force for force, but no force if no force was used.
Superstring theories provide a framework in which the force of gravity may be united with the other three forces in nature: the weak, electromagnetic and strong forces. Recent progress has shown that the most promising superstring theories follow from a single theory. For the last generation, physicists have studied five string theories and one close cousin. Recently it has become clear that these five or six theories are different limiting cases of one theory which, though still scarcely understood, is the candidate for superunification of the forces of nature.
The jet stream is a very strong force and pushing a balloon into it is like pushing up against a brick wall, but once we got into it, we found that, remarkably, the balloon went whatever speed the wind went.
There are 15 constants- the gravitational constant, various constants about the strong and weak nuclear force, etc.- that have precise values. If any one of those constants was off by even one part in a million, or in some cases, by one part in a million million, the universe could not have actually come to the point where we see it. Matter would not have been able to coalesce, there would have been no galaxy, stars, planets or people
We could get together all over the world, all races, hold hands together, and hum to death, and try to move the moon where the sun is, move the sun where the moon is at, and send a little piece of a star down there and burn all our asses up. We could get into the science, and make bombs and all that stuff, but you still ain't gonna hit the supreme force or the power that put all this into motion.
Government force is derived from the sum of the physical force each citizen could exert which by one citizen himself would be ineffective, but when summed from the force of all the area's citizens indeed composes a power no citizen or group can withstand. That force is then rightly but justly to be used against those who violate the foundation pillars of freedom.
Only by binding together as a single force will we remain strong and unconquerable.
My work during the 1970s has been mainly concerned with the implications of the unified theory of weak and electromagnetic interactions, with the development of the related theory of strong interactions known as quantum chromodynamics, and with steps toward the unification of all interactions.
The incomplete knowledge of a system must be an essential part of every formulation in quantum theory. Quantum theoretical laws must be of a statistical kind. To give an example: we know that the radium atom emits alpha-radiation. Quantum theory can give us an indication of the probability that the alpha-particle will leave the nucleus in unit time, but it cannot predict at what precise point in time the emission will occur, for this is uncertain in principle.
Any schoolboy could see that man as a force must be measured by motion, from a fixed point.
