The distinctive and amusing term "barn" originated with two Purdue University physicists working on the Manhattan Project in 1942—and it was classified information by the US government until after World War II.
For 33 particle physicists, the year 2005 was a great experiment in science communication. To support the World Year of Physics, these brave souls had agreed to share their thoughts and their lives with the public, blogging on the Quantum Diaries Web site.
It looks like a simple silver trailer, but it's more like a shoe store on wheels. Mike Sitarz pulls his metal trailer, better known among Fermilab employees as the "shoemobile," behind the Technical Division industrial buildings at 8 a.m. every Tuesday.
Collider luminosity is the key to particle physics discoveries. Fermilab and labs around the world have spared no effort in increasing their collider luminosities.
Unveiling the three-dimensional structure of proteins thrills scientists. While the potential for understanding the folding and function of enzymes is truly exciting by itself, exploring macromolecule structures also satisfies a more fundamental urge: to see the invisible.
In high-energy collisions, luminosity, or beam brightness, isn't the only thing to consider; low background noise at the detectors is also important. When wayward particles bounce around inside detectors, they can mimic real collisions, muddy results, and even damage parts of the collider.
