 David Gross and Frank Wilczek - Nobel Prize 2004: Department of Physiccs, Princeton University
Past Princeton faculty members David Gross and Frank Wilczek (*73), along with David Politzer, were today awarded the 2004 Nobel Prize in Physics for their 1973 discovery of asymptotic freedom.
Gross, Wilczek, and Politzer showed that a version of non-abelian gauge theory, soon to be known as quantum chromodynamics, or QCD, possessed asymptotic freedom and Gross and Wilczek derived precise predictions for the behavior of electron-proton cross-sections at high energies.
David Gross was a professor in the Physics Department, and Frank Wilczek was his thesis student when their papers demonstrating asymptotic freedom and formulating QCD as the quantum field theory of the strong interactions appeared.

I was delighted to wake up on the morning of October 5 and find that David Gross, David Politzer and Frank Wilczek had been awarded the 2004 Nobel Prize for the discovery of asymptotic freedom in the theory of the strong interaction.
David Politzer was particularly active in this stage, teaching us that perturbation theory contained both long distance parts and short distance parts, which need to be separated.
The discovery that earned David Gross, David Politzer, and Frank Wilczek the 2004 Nobel Prize in Physics—that the strong, or "color," force binding quarks together grows weaker as two quarks become closer, and is stronger as quarks are pulled apart—spawned a new physics theory with a profound impact on experimental nuclear and particle physics.

PASADENA, Calif.--Hugh David Politzer has won the 2004 Nobel Prize in physics for work he began as a graduate student on how the elementary particles known as quarks are bound together to form the protons and neutrons of atomic nuclei.
Politzer joined the Caltech faculty as a visiting associate in 1975, the year after finishing his Harvard Ph.D. in physics and three years after publishing his work on asymptotic freedom.
Politzer's initial foray into the public limelight came in 1989, when he was recruited to play physicist Robert Serber in the movie Fat Man and Little Boy, which recounted the story of the Manhattan Project and starred Paul Newman as the hard-driving project leader Gen. Leslie Groves.

Politzer, who achieved an international reputation in physics while he was still a graduate student, says he is not contemplating a career switch.
According to Politzer, one of the movie's key themes is how the scientific and military personnel at Los Alamos coped with one another's very different styles—and with the idea that the rational pursuit of physics might someday have the irrational consequence of blowing up the planet.
Politzer says that throughout his stay, he was amazed by the talent of the professional actors in the cast.

The strong force seemed to act in an odd fashion: although quarks were never observed apart from one another, they appeared to behave almost like free particles when inside protons and neutrons.
Politzer described quarks as exhibiting what is known as asymptotic freedom: they are drawn to each other very strongly when they are far apart but only weakly when close together.
Frank Wilczek, who, independently of Politzer, came up with the explanation for the strong force at the same time he did.

With his first published journal article in 1973, David Politzer, 55, now a professor of theoretical physics at the institute, explained a new, counter-intuitive property that showed how the smallest units of matter, known as quarks, stick together to form neutrons and protons.
Politzer, a New York City native, presented a calculation in his journal study showing the attractive force between quarks becomes weaker when close and stronger when they move apart.
Politzer will share the $1.36 million prize with two researchers who came to the same conclusion independently at Princeton University David Gross, now of UC Santa Barbara, and Frank Wilczek, now of the Massachusetts Institute of Technology.

 Cal alum David Gross (PhD '66) shares Nobel Prize in Physics
"David was probably the most talented graduate student that I had, and I had a huge number of graduate students," said Chew, now retired from the faculty but still active in elementary particle theory.
The discovery of Gross, Wilczek and Politzer came out of an earlier breakthrough that described electromagnetism, the force that acts between charged particles, such as electrons and protons, and which governs all chemical interactions.
"This development that David, Politzer and Wlczek achieved allowed the computational techniques that people had developed in connection with QED in describing atoms to be applied to the nucleus," Chew said.

The 2004 Nobel Prize for Physics has been awarded to David Gross, David Politzer and Frank Wilczek for their "discovery of asymptotic freedom in the theory of the strong interaction".
Politzer and Wilczek were both still graduate students in June 1973 - Wilczek working with Gross - when their work appeared in two consecutive papers in Physical Review Letters, in fact the last two papers of volume 30.
The rest, as they say, is history, as the discovery of Gross, Politzer and Wilczek in a sense not only liberated quarks deep within the proton but also liberated theorists to develop a quantum-field theory of the strong interaction.

 Nobel Honours Sub-Atomic World
Three decades ago, Gross, Politzer and Wilczek came up with a theory to describe the force that holds together quarks, the elementary particles with which nature constructs the neutrons and protons that make up the nuclei of atoms.
They fancifully described their force in terms of "colour", saying that quarks could be red, green or blue, rather like electrical charge can be positive or negative; and just as electrical opposites attract, so combinations of quark colour can make for stable collections of quarks.
Gross is attached to the Institute for Theoretical Physics, at the University of California-Santa Barbara; Politzer is from the California Institute of Technology; and Wilczek works at the Massachusetts Institute of Technology Center for Theoretical Physics.

David Gross, David Politzer and Frank Wilczek discovered a property of the strong interaction which explains why quarks may behave almost as free particles only at high energies.
Admittedly, when the quarks have moved away from each other, they are influenced by increasingly strong forces that eventually lead to the creation of new quark-antiquark particles, and a shower of particles arises in the direction of the original quarks and antiquarks respectively.
