A Guch-a-riffic chemistry tutorial!

Guch Explains I have good news and bad news. The bad news is that I'm not going to add to the list below anymore because it's a pain to get everything formatted for the Interwebs. The good news is that I'm going to start adding new questions in blog format over at . Check it out, and email me any questions you've got at .

Scientists were today able to dispel the age-old belief that no two snowflakes are the same, using state of the art microscopy and by catching flakes as they fell in specially designed equipment while sitting at a table outside a pub in Norwich.

Coriolis-like effect found 184 years before Coriolis - physics-math - 14 January 2011

While trying to prove that the Earth is fixed in space, an Italian priest described something similar to the Coriolis effect – the slight deflection experienced by objects moving in a rotating frame of reference – nearly 200 years before mathematician Gustave Coriolis worked it out in 1835. In 1651, Giovanni Riccioli published 77 arguments against the idea that the apparent motions of the heavens were due to the Earth's rotation and orbit around the sun. These included claims that Hell would be in the wrong place, aesthetic concerns over proportion and harmony, and more scientific approaches. Now, Christopher Graney at Jefferson Community and Technical College in Louisville, Kentucky, has translated them from Latin, and discovered that Riccioli conjectured phenomena resembling the Coriolis effect ( In reality, the Coriolis effect is subtle, noticeable mainly in large-scale systems such as weather patterns and ocean currents.

Laser Crosswalk Saves Pedestrians From a Painful Death. CERN: Light Speed May Have Been Exceeded By Subatomic Particle. GENEVA — One of the very pillars of physics and Einstein's theory of relativity – that nothing can go faster than the speed of light – was rocked Thursday by new findings from one of the world's foremost laboratories.

CERN: Light Speed May Have Been Exceeded By Subatomic Particle

European researchers said they clocked an oddball type of subatomic particle called a neutrino going faster than the 186,282 miles per second that has long been considered the cosmic speed limit. The claim was met with skepticism, with one outside physicist calling it the equivalent of saying you have a flying carpet. In fact, the researchers themselves are not ready to proclaim a discovery and are asking other physicists to independently try to verify their findings.

Quantum Computing: Will It Be a Leap in Human Evolution?

Oxford Professor David Deutsch, quantum-computing pioneer, who wrote in his controversial masterpiece, Fabric of Reality says: "quantum computers can efficiently render every physically possible quantum environment, even when vast numbers of universes are interacting. The Higgs Boson explained by PhD Comics. Higgs Found. Finally, physics’s zoo of subatomic particles is full.

Higgs Found

Scientists have almost certainly snared the Higgs boson, the last particle waiting to be roped into the fold. Decades after it was proposed, the Higgs emerged in the shards of particle collisions at the world’s most powerful accelerator, the Large Hadron Collider at the CERN laboratory near Geneva. Higgs boson: What's it for? I have no idea, says Prof. Laws of physics vary throughout the universe, new study suggests. A team of astrophysicists based in Australia and England has uncovered evidence that the laws of physics are different in different parts of the universe.

Laws of physics vary throughout the universe, new study suggests

The team -- from the University of New South Wales, Swinburne University of Technology and the University of Cambridge -- has submitted a report of the discovery for publication in the journal Physical Review Letters. A preliminary version of the paper is currently under peer review. The report describes how one of the supposed fundamental constants of Nature appears not to be constant after all. Instead, this 'magic number' known as the fine-structure constant -- 'alpha' for short -- appears to vary throughout the universe. Electricity. Stuff under an electron microscope.

Used dental floss. Arranca la búsqueda de la 'partícula Dios' La sala de reuniones del partido tory está llena de militantes que charlan tranquilamente cuando, de pronto, la señora Thatcher entra por la puerta. A medida que Thatcher camina por la habitación, los militantes más cercanos forman corrillos a su alrededor y, en consecuencia, dificultan el movimiento de su líder. Los militantes representan el campo de Higgs, una forma de energía que impregna todo el espacio y confiere masa a las partículas (como Thatcher). Un protón, por ejemplo, no tendría masa si no fuera por el campo de Higgs. Sin ese campo misterioso, todos seríamos livianos como el fotón, y nos moveríamos, como él, a la velocidad de la luz.

Mind blowing physics engine demonstration. Serious Flaw Emerges In Quantum Cryptography. The problem of sending messages securely has troubled humankind since the dawn of civilisation and probably before. In recent years, however, physicists have raised expectations that this problem has been solved by the invention of quantum key distribution. This exploits the strange quantum property of entanglement to guarantee the secrecy of a message. Entanglement is so fragile that any eavesdropper cannot help but break it, revealing the ruse. So cryptographers can use it to send a secure key called a one time pad that can then be used to encrypt a message.

New kind of light created in physics breakthrough. Physicists have created a new kind of light by chilling photons into a blob state. Just like solids, liquids and gases, this recently discovered condition represents a state of matter. Called a Bose-Einstein condensate, it was created in 1995 with super-cold atoms of a gas, but scientists had thought it could not be done with photons, which are basic units of light.
