Discovery of asymptotic freedom in the theory of strong interactions of elementary particles.
The impact of this on theoretical physics will be comparable to the impact of the 1973 discovery of asymptotic freedom on the high energy physics.
While strong supporting evidence for the particle physics theory of Quantum Chromodynamics (QCD) has been found in high energy collisions in experimental tests using perturbativetreatments because of its asymptotic freedom behavior, the perturbative procedures have proven problematic for low-energy QCD, since the running coupling constant goes beyond 1.
Among the areas they consider are breaking the symmetry, towards the standard model, renormalization, asymptotic freedom, quark confinement and strings, the lattice, confrontation with experiments, and supersymmetry and supergravity.
It explains things like asymptotic freedom, quarks, coins spinning on a table, and the way subatomic particles behave with gravity -- all things I admit I've never spent a second wondering about.
Before the researchers came up with the concept of asymptotic freedom, any relationship among the plethora of new particles observed during atom-smashing experiments remained hidden.
Exploring how natural scientists have integrated notions of human free will into their models of the world, he ponders such matters as the age of neuroscience and the end of freedom; complexity, spontaneity, and social behaviors in biological evolution; freedom and the emergence of culture; forms of freedom, as-if freedom, and asymptotic freedom as a challenge to neurophilosophy; a speech to the scientifically cultured despisers of religion; and freedom and transcendence.
