In 1905, Albert Einstein published his Special Theory of Relativity and overthrew the notions of absolute space and time. His later General Theory of Relativity was so revolutionary that even he had trouble accepting its full implications.
This mural in the Soudan Underground Laboratory, located in Minnesota half a mile underground, was designed by artist Joseph Giannetti. Its theme is matter and energy, and--more specifically--neutrino physics.
Waves describe some of the most extraordinary phenomena in the world. Waves can be simple—the sound of a flute playing a sustained, single note—or they can be complicated mixtures—a musical chord, for example, which is a combination of many sound waves.
Speaking experimentally, the past decade has been the "Decade of the Neutrino." It produced neutrino experiments across three continents, going from the lab, to the nuclear reactor, to the atmosphere, to the sun, and back to the nuclear reactor.
On the night of April 27, 2002, the Apache Point 3.5 m telescope in New Mexico captured the light signature of SDSS 1148+5251, the most distant quasar known. A quasar is a compact, ultraluminous object thought to be powered by material falling into a giant black hole.
In 1967, Don Young was among a handful of physicists working to turn a dream into the research institution that would become Fermilab. His first job found him in charge of building the linear acceleratorand then 30 years later, the Linac would help save his life.
