LHC Detects Evidence of New Physics | Wired Science After nearly 6 months of smashing particles, the Large Hadron Collider has seen signs of something entirely new. Pairs of charged particles produced when two beams of protons collide seem to be associated with each other even after they fly apart. “It is a small effect, but it is very interesting in itself,” said physicist Guido Tonelli, spokesperson for the LHC’s CMS experiment. Tonelli and colleagues announced the results in a seminar at CERN September 21 and in a paper submitted to the Journal of High Energy Physics. The LHC finally got up and running in March after more than a year of false starts. Beams of protons were smashed together in the 17-mile-long ring at energies of 7 teraelectronvolts (TeV) — three times the energy that had been achieved before. When two protons collide, they produce a flurry of smaller, short-lived charged particles that fly away from each other at certain angles and speeds. “We are here today because we didn’t succeed to kill it,” Tonelli said.

10 Strange Things About The Universe Space The universe can be a very strange place. While groundbreaking ideas such as quantum theory, relativity and even the Earth going around the Sun might be commonly accepted now, science still continues to show that the universe contains things you might find it difficult to believe, and even more difficult to get your head around. Theoretically, the lowest temperature that can be achieved is absolute zero, exactly ?273.15°C, where the motion of all particles stops completely. One of the properties of a negative-energy vacuum is that light actually travels faster in it than it does in a normal vacuum, something that may one day allow people to travel faster than the speed of light in a kind of negative-energy vacuum bubble. One prediction of Einstein’s theory of general relativity is that when a large object moves, it drags the space-time around it, causing nearby objects to be pulled along as well. Relativity of Simultaneity This is similar to arranging tiles evenly on a floor.

In QCD, it is the vacuum that imprisons the quarks. A pair of virtual particles from the vacuum are given enough energy that they become real, and fly apart in opposite directions. "There's no doubt.

Robert Lanza, M.D.: Does the Past Exist Yet? Evidence Suggests Your Past Isn't Set in Stone Recent discoveries require us to rethink our understanding of history. "The histories of the universe," said renowned physicist Stephen Hawking "depend on what is being measured, contrary to the usual idea that the universe has an objective observer-independent history." Is it possible we live and die in a world of illusions? In 2002, scientists carried out an amazing experiment, which showed that particles of light "photons" knew -- in advance −- what their distant twins would do in the future. More recently (Science 315, 966, 2007), scientists in France shot photons into an apparatus, and showed that what they did could retroactively change something that had already happened. Of course, we live in the same world. But what about dinosaur fossils? Like the light from Wheeler's quasar, historical events such as who killed JFK, might also depend on events that haven't occurred yet. History is a biological phenomenon − it's the logic of what you, the animal observer experiences.
Boy discovers microbe that eats plastic It's not your average science fair when the 16-year-old winner manages to solve a global waste crisis. But such was the case at last May's Canada-Wide Science Fair in Ottawa, Ontario, where Daniel Burd, a high school student at Waterloo Collegiate Institute, presented his research on microorganisms that can rapidly biodegrade plastic. Daniel had a thought it seems even the most esteemed PhDs hadn't considered. Editor's note: There are two high school students who have discovered plastic-consuming microorganisms. Could those microorganisms be bred to do the job faster? That was Daniel's question, and he put to the test with a very simple and clever process of immersing ground plastic in a yeast solution that encourages microbial growth, and then isolating the most productive organisms. The preliminary results were encouraging, so he kept at it, selecting out the most effective strains and interbreeding them.

Simple mechanisms explained Email Below you’ll find animated diagrams and explanations of how various mechanisms work. Some of these have been crucial to major evolutions in mechanisms and technology, and allow us to do anything from fire weaponry to make cars move with the press of a pedal. Maltese Cross mechanism powers second hand movement in the clock: Radial engines are used in aircraft. Reciprocating movements power steam engines in locomotives: Sewing machine: Manual transmission mechanism, also known as “stick shift” is used to change gears in vehicles: This mechanism is called constant-velocity joint and is used in front-wheel drive vehicles: Torpedo-boat destroyer system is used to destroy fleet in naval military operations: The Wankel engine is a type of internal combustion engine which uses a rotary design to convert pressure into a rotating motion instead of using reciprocating pistons: + Bonus – mechanism you can watch forever Leave your comment: You may also like these posts:
10 Amazing Tricks to Play with your Brain / Mind Mind is the aspect of intellect and consciousness experienced as combinations of thought, perception, memory, emotion, will and imagination, including all unconscious cognitive processes. Mind manifests itself subjectively as a stream of consciousness. Neuroanatomists usually consider the brain to be the pivotal unit of what we refer to as mind. 10. At first this might sound like a bad practical joke. 9. In case you experience an injury, then see the injured part with an inverted binoculars, soon your pain will seem to be decreasing in its magnitude. Recently, a reasearch at Oxford University has lead to the discovery of a new pain killer – the inverted binoculars. Source: ( Link) 8. This requires two chairs and a blind fold. The Pinocchio effect is an illusion that ones nose is growing longer, as happened to the literary character, Pinocchio when he told a lie. 7.
