	THE A-TEAM - John Singleton — Exclusive Interview
		Collider: And one last question, have you guys already talked with the studiowho is producing this?
		Collider: So you basically think that the people who were fans of those kinds of 80’s films are really going to be on board with this.
		Collider: So, with the people who sign onto the project, are you going to make them sign on for multiple films?

	Collider - Wikipedia, the free encyclopedia
		A collider is a type of a particle accelerator with two opposite beams of the particles.
		Collider: Two beams of particles are accelerated and the beams are directed against each other, so that the particles collide while flying into opposite directions.
		Colliders may either be ring accelerators or linear accelerators.

	Physicists Proposing New U.S. Linear Particle Collider
		They are building the case for a linear collider in anticipation of a larger meeting of American and international physicists this summer in Snowmass, Colo. At that meeting, sponsored by the American Physical Society, advocates of a variety of collider proposals will present their best arguments for their proposals to the larger community of physicists.
		Researchers who favor the linear collider proposal are hoping to earn the approval of the subpanel and the physics community at large by working to keep the costs of their proposal down, staying away from problems that sank the Superconducting Supercollider, and showing that a linear collider can complement the abilities of the LHC.
		Colliders are typically built in a ring-shaped structure, with particles orbiting around the ring at high speeds.

	Physicists meet to discuss collider
		The future of the linear collider, and the options for its design, was discussed by Gerald Dugan, professor of physics at Cornell, at the joint meeting of the American Physical Society (APS) and the High-Energy Astrophysics Division of the American Astronomical Society, April 22, at the Albuquerque, N.M., Convention Center.
		The linear collider would seek to detect the Higgs boson, the holy grail of particle physics, and would also explore supersymmetry and antimatter, providing fundamental details abut the origin of the universe, the structure of space and the nature of matter itself.
		Cornell's interest in the linear collider spans all four designs because the LEPP is determined to play a major role in the machine's development.

	The Future of the Superconducting Super Collider
		The superconducting super collider as we know it is now dead, yet the quest for a comprehensive understanding of the world around us lives on.
		Although Congress intensely criticized the super collider project for failing to receive substantial foreign funding, it was never clear that Congress was prepared to share with other nations the jobs and technological benefits that would have flowed from a true partnership.
		The super collider never captured broad support from the American public, in no small part because its scientific promise was difficult to understand even by those who are scientifically literate.

	HIGH LUMINOSITY MUON COLLIDER DESIGN
		Hadron collider energies are limited by their size, and technical constraints on bending magnetic fields.
		The beam will need careful preparation before injection into the collider, and a collimation system will have to be designed to be located on the opposite side of the ring from the detector.

	The Superconducting Super Collider
		The Collider was an oval shaped accelerator the circumference of which was 54 miles.
		Collider refers to the main purpose of the laboratory, colliding protons into each other so scientists and physicists could study the resulting shower of smaller particles.
		In a collider, on the other hand, two particles of equal energy coming together have no net motion, and collision makes all their energy available for new reactions and the creation of new particles.

	Collider Summary
		When high energy particles collide with a stationary target, only a relatively small fraction of their energy is available to take part in the reaction.
		When an experiment is about to be carried out, the particles are released from the storage ring and allowed to collide with a second beam traveling in the opposite direction.
		The largest and most powerful circular colliders in existence are located at the Fermi National Accelerator Laboratory (Fermilab) near Chicago, Illinois, at the Centre Européen pour la Recherche Nucléair (CERN) in Geneva, Switzerland, and at the Deutsches Electronen-Synchrotron (DESY) in Hamburg, Germany.

		One policy controls the method to be used when collided against and one for when this node collides with another.
		There are 5 colliders in the scene which are spheres, each with the force of gravity applied.
		There is a lack of smoothness due partially to the lack of a high res timer, partially do to GC since I have not fully optimized for leaking objects (there is lots and lots of vector math which requires lots and lots of temp tuples).

		Any collider is extendable by 20-30% in energy so if no light Higgs is found the energy can be increased to find the heavier state.
		Such a polarization analysis is extremely difficult at a hadron collider, but entirely feasible at the lepton collider.
		Thus the lepton collider will be essential to learning what we need to know to formulate the next stage of progress.

	Scientific American: The Collider Calamity (Site not responding. Last check: )
		Colliders at the Fermi National Accelerator Laboratory (Fermilab), Stanford Linear Accelerator Center (SLAC) and Brookhaven National Laboratory have discovered exotic particles such as the top quark and revealed phenomena that hint at new laws of physics.
		And funding for Brookhaven's Relativistic Heavy Ion Collider (RHIC) is so tight that the lab could not have run its full slate of experiments this year without $13 million raised by a New York billionaire.
		But America's physicists yearn to work on the high-energy frontier, and their last great hope is the International Linear Collider, which would probe the new particles revealed by the LHC.

	Report of the PPARC Linear Collider Steering Group: The UK Linear Collider Project
		The Linear Collider Flavour Identification (LCFI) collaboration is one of the UK flagship detector RandD projects and should be maintained at least at the current level into the foreseeable future and strengthened where possible.
		The Linear Collider Flavour Collaboration (LCFI) comprises Bristol, Lancaster, Liverpool, Oxford, QMUL and RAL [7].
		Formed in 1998, this collaboration is engaged in physics studies to determine the requirements for a vertex detector at the LC and in detector RandD aimed at satisfying these requirements by extending the capability of a CCD-based system beyond that used successfully in the 307 Mpixel SLD vertex detector.

	Large Hadron Collider Summary
		The collider is contained in a 27 km circumference tunnel located underground at a depth ranging from 50 to 150 metres
		It was formerly used to house the LEP, an electron-positron collider.
		Perhaps the simpliest and strongest argument for the safety of colliders such as the LHC comes from the simple fact that cosmic rays of much higher energies than the LHC can produce have been bombarding the Earth, Moon and other objects in the solar system for billions of years with no such effects.

	Large Hadron Collider - Wikipedia, the free encyclopedia
		The tunnel was formerly used to house the LEP, an electron-positron collider.
		As with the Relativistic Heavy Ion Collider (RHIC), people both inside and outside of the physics community have voiced concern that the LHC might trigger one of several theoretical disasters capable of destroying the Earth or even the entire Universe.
		Perhaps the strongest argument for the safety of colliders such as the LHC comes from the simple fact that cosmic rays of much higher energies than the LHC can produce have been bombarding the Earth, Moon and other objects in the solar system for billions of years with no such effects.

	Super Monkey Collider Loses Funding \| The Onion - America's Finest News Source
		The collider, which was to be built within a 45-mile-long circular tunnel, would accelerate monkeys to near-light speeds before smashing them together.
		Scientists insist the collider is an important step toward understanding the universe, because no one can yet say for certain what kind of noises monkeys would make if collided at those high speeds.
		Last month, it was finally decided that the collider would employ a system in which the monkeys run through the tunnels chasing holographic projections of bananas.

	Unity Components – Mesh Collider
		The Mesh Collider builds its collision representation from the Mesh attached to the GameObject, and reads the properties of the attached Transform to set its position and scale correctly.
		If an object collides with a mesh that will be back face culled graphically it will also not collide with it physically.
		When a collision between two Colliders occurs and if at least one of them has a Rigidbody attached, three collision messages are sent out to the objects attached to them.

	Record-breaking luminosity boosts discovery potential at Fermilab's Tevatron collider
		Since restarting the Tevatron collider after a scheduled shutdown in December 2004, the collider has produced an integrated luminosity of 872 inverse picobarns-a measure for the number of collisions achieved.
		Producing antiprotons is not easy, by any standard: colliding beams of protons with a fixed target made of nickel, with every million collisions producing about 18 antiprotons.
		The Large Hadron Collider (LHC) at the European laboratory CERN will be turning on in 2007, with collisions at an energy seven times higher than the Tevatron can produce.

	CD Baby: COLLIDER: Blowing Shit Up
		A collider is a high-tech machine used to generate interesting bits of matter by smashing together other not-quite-as-interesting bits of matter at extremely high speeds.
		Second, Collider are nasty in the extreme, bypassing any semblance of '90s political correctness in their zeal to blow out the back of your skull before you've noticed the gun barrel between your teeth.
		Beginning with the manic anthem "Traffic," through the menacing "Minotaur," and ending with the optimistic elegy "Rise and Shine," Collider masterminds Jed Davis and Sean Gould explore the nastier side of human nature with an unerring and honest eye.

	First Linear Collider Offers New Possibilities
		The SLAC Linear Collider (SLC) was based on new accelerator technology and offered the possibility of reaching higher-energy electron collisions in a more cost-effective manner than conventional ring designs.
		In 1998, the first "disruption enhancement" was achieved, in which beam density is high enough to cause the beams to shrink during the collision, an effect that doubles luminosity.
		This prototype linear collider also points the way to a larger collider that would enable precision studies of the Higgs boson and other ultraheavy particles thought to have existed in profusion during the Big Bang creation of the universe.

	The Large Hadron Collider
		In this way the LHC can be seen as a discovery machine with a dynamic range of discovery from energy scales of 5 MeV in the case of B-physics to a few TeV for the discovery of new vector bosons or quark compositeness.
		For while a proton-antiproton collider has the advantage that both counter-rotating beams can be kept in the same beam pipe, producing the enormous amounts of antiprotons required for the high luminosity is not realistic and would be more expensive than the proton-proton solution with separate beam pipes.
		The charge asymmetry introduced with a proton-proton collider is not a serious problem for the physics analysis.
