On today's show, apparently someone left the God particle in a bar or something, it's always sunny in Chile, and how to be "that guy" by bringing your 27-inch monitor to a coffee shop. Oh, and Isaiah Mustafa, otherwise known as the Old Spice guy, is now making custom videos for Twitter people. Without his shirt, of course.

GENEVA--The Large Hadron Collider is a marvel of both brute-force and sophisticated engineering.
To start, look at the mostly circular cavern, 27 kilometers in circumference, that houses the accelerator. It's got an average depth of 100 meters, but in fact it's actually horizontal: its plane is tilted 1.4 percent to keep it as shallow as possible to minimize the expense of digging vertical shafts while placing the cavern in a subterranean sandstone layer.
Tidal forces from the moon cause the Earth's crust to rise about 25cm, an effect that increases the LHC's circumference by 1mm. … Read more
GENEVA--The LHC shows science on an unusually large scale.
Thousands of researchers are involved in each of the Large Hadron Collider's major experiments, and more are there to operate the beam itself. Something like half the world's particle physicists are involved one way or another with the LHC, estimated Maria Isabel Pedraza Morales, a University of Wisconsin physicist who works on the ATLAS experiment.
The accelerator is likely to lead to hundreds of academic papers and doctoral dissertations in coming years. CERN's hallways are teeming with an international mix of senior physicists and young researchers just getting … Read more
GENEVA--There are two kinds of physicists in the world, broadly speaking: those with the equation-covered blackboards, and those with the scales, thermometers, and pressure gauges.
The theoretical physicists have had the upper hand for years, but something new has begun tilting the balance toward the experimentalists: the Large Hadron Collider.
This mammoth, $8 billion particle accelerator is housed in a ring 27km in circumference bored about 100 meters beneath a somewhat pastoral valley west of Geneva and operated by a multinational nuclear physics organization called CERN, which was founded in 1954.
The LHC is now speeding protons nearly to the … Read more
Researchers at CERN, the European Organization for Nuclear Research in Geneva, did something gutsy but smart Tuesday: they revved the Large Hadron Collider up to a new energy level in full public view.
Happily for the dozens of scientists and engineers in attendance, the LHC successfully reached its goal of a 7 TeV energy level--two beams of protons each at 3.5 trillion electron-volt energies whizzed in opposite directions and eventually collided at several points in the gigantic underground ring-shaped particle accelerator.
Scientific projects by and large are hardly cloaked in secrecy. But the LHC's run Tuesday was … Read more
Professor Peter Higgs will have to wait at least a few additional seasons to find out whether his long-held theory on how matter has mass is right.
That's because officials announced Tuesday that the Large Hadron Collider (LHC), which could confirm the existence of a theoretical particle name after Higgs, will remain shut down until at least early spring.
The LHC, the world's largest particle collider, is located in a nearly 17-mile-long circular tunnel along the French-Swiss border about 330 feet underground. Built by the European Organization for Nuclear Research (or CERN), it promises to push forward theories … Read more
