Calibration tool will reveal when hypothetical particles are detected Several research projects are underway to try to detect particles that may make up the mysterious "dark matter" believed to dominate the universe's mass. But the existing detectors have a problem: They also pick up particles of ordinary matter -- hurtling neutrons that masquerade as the elusive dark-matter particles the instruments are designed to find. MIT physicist Jocelyn Monroe has a solution. A new detector she and her...

The European Organization for Nuclear Research (CERN) officially celebrated its experiment to discover the origins of the universe. It was a large inauguration, despite a technical hitch last month that shut it down within days of starting. Taking particular pride was Robert Aymar, director general of CERN. "When CERN chooses to be audacious, amazing things can happen," Aymar told government ministers, scientists and diplomats gathered for the event. The CERN experiment will investigate the...

The massive particle collider built to simulate the conditions of the "Big Bang" will not restart until spring 2009 after a technical glitch forced its shutdown, according to the European Organization for Nuclear Research, or CERN. Experts have been down into the 17-mile tunnel housing the Large Hadron Collider (LHC) to see what they could determine about the damage. A helium leak into the tunnel housing, the biggest and most complex machine ever made, forced CERN to shut down its LHC...

By The Associated Press GENEVA (AP) - A small blip on a computer screen sent champagne corks popping among physicists in Switzerland. Near Chicago, researchers at a "pajama party" who watched via satellite let out an early morning cheer.The blip was literally of cosmic proportions, representing a new tool to probe the birth of the universe.The world's largest atom smasher passed its first test Wednesday as scientists said their powerful tool is almost ready to reveal how the tiniest...

By James Thalman Deseret News and Alexander G. Higgins Associated Press Moving fast enough to circle a 17-mile-long underground tunnel nearly 11,000 times a second, streams of atomic particles signaled the start of a new era of research that scientists believe could unravel the universe's deepest mysteries. At 2:28 a.m. MDT Wednesday, some 14 years and $10 billion after it was first designed, the Large Hadron Collider laboratory near Geneva, Switzerland, was activated, officially becoming...

By Rebecca McQuillan reports LOOK outside your window. Is it a beautiful day? Is it raining again? If so, welcome it, go out now in your socks and run about in it. Kiss a stranger. Make the most of every minute, because the doomsayers predict that we might not be here at Christmas. A tiny minority believe that the European Nuclear Research Centre (CERN) Big Bang Experiment, due to begin on Wednesday, is a folly that could create a black hole the whole world will be sucked into. Most...

UC Santa Cruz physicists involved in major international physics experiment The field of particle physics is poised to enter unknown territory with the startup of a massive new accelerator--the Large Hadron Collider (LHC)--in Europe this summer. On September 10, LHC scientists will attempt to send the first beam of protons speeding around the accelerator. The LHC will put hotly debated theories to the test as it generates a bonanza of new experimental data in the coming years. Potential...

By Little, Joseph This article examines the role of the liquid drop analogy in George Gamow's theory of nuclear structure and his subsequent derivation of nuclear energy. It argues that the correspondences constituting the analogy served distinct but cooperative ends, requiring Gamow to posit a relatively simple nuclear geometry that set him apart from his contemporaries, mostly shell theorists, and led to his successful derivation of nuclear energy in the fall of 1928. Analogy has long...

One of the most significant moments in the history of science may come after a new particle collider starts work this year beneath the Swiss-French border, according to a renowned physicist, Brian Greene. The Large Hadron Collider just might prove that the controversial "theory of everything," string theory, is true. Greene, professor of physics and mathematics at Columbia University, New York City, and author of best-selling books on string theory, spoke Tuesday at Brigham Young...

High-energy physicists devoted to recreating the conditions at the beginning of the universe have for the first time observed a new way to produce those basic particles of atoms, protons and neutrons.Confirming a decades-old prediction, the physicists with the CLEO collaboration say they observed a rare and extremely short-lived subatomic particle with the unusual name of "charmed-strange meson" decay into a proton and anti-neutron.Detection of the event, which the collaboration made public...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
