In physics the technique provides some of the first general exact results in four-dimensional quantum field theory, including a quantitative description of confinement via magnetic monopole condensation. In mathematics the topological study of smooth four-dimensional manifolds has been revolutionized. Applications of high-temperature superconductors approach the marketplace. T c superconductors are being used in magnetometer sensors, prototype filters for cellular-phone base stations and magnetic resonance applications. T c materials such as nondestructive testing, medical and geophysical sensors, communications, and multichip modules.
Inventions born of necessity offer new tools for the blind to study and do science.
New ways of rendering advanced mathematics are removing a major barrier to the pursuit of science by the blind. Congressional Fellows add their expertise to the political process. Sponsored by AIP, AGU and APS, physicists help to develop and review legislation on issues ranging from nuclear waste to patent law. Past participants in the program report a gratifying experience.
