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.
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.
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.
When the 10th issue of symmetry magazine came out on October 12, the magazine's Web server crashed unexpectedly. Looking at the Web traffic statistics, the reason became obvious: symmetry had been "slashdotted."
When physicists organized the first Particles and Nuclei International Conference in 1963, nobody thought that the acronym PANIC could cause trouble in getting the word out about the meeting. That was before the now-common use of email.
Students around the world are familiar with the periodic table of elements, a chart that outlines how protons, neutrons, and electrons form more than 100 different types of atoms.
Few periods in history were shaped by science as much as the 1950s. The Cold War was in full swing. The space race was finishing its first lap with Sputnik's launch. The Manhattan Project remained fresh in everyone's minds.
The weak force is responsible for the decay of matter: unstable particles made of heavy quarks and antiquarks decay into particles made of their lighter cousins.
