"Scientists from Oxford University have made a significant step towards an ultrafast quantum computer by successfully generating 10 billion bits of quantum entanglement in silicon for the first time -- entanglement is the key ingredient that promises to make quantum computers far more powerful than conventional computing devices."

Single photons are the smallest quantities of light and, despite having no mass, have many properties in common with particles. In fact, physicists often think of photons as particles -- particles that sometimes behave like waves. Physicists sometimes describe all particles as waves -- even those with mass, such as electrons and protons -- in order to better understand certain aspects of their behavior.

"Now a different team at the same lab reports findings that, they say, cast doubt on that surprising result. The Icarus team at the Icarus experiment says that because the neutrinos sent from Cern do not appear to lose energy on their journey, they must not have exceeded the speed of light along the way."

"While studying graphene's electronic properties, professor Chris Regan and graduate student Matthew Mecklenburg found that a particle can acquire spin by living in a space with two types of positions -- dark tiles and light tiles. The particle seems to spin if the tiles are so close together that their separation cannot be detected. "An electron's spin might arise because space at very small distances is not smooth, but rather segmented, like a chessboard," Regan said."

HyperPhysics is an exploration environment for concepts in physics which employs concept maps and other linking strategies to facilitate smooth navigation. For the most part, it is laid out in small segments or "cards", true to its original development in HyperCard. The entire environment is interconnected with thousands of links, reminiscent of a neural network.

In this three-part documentary series, Professor Jim Al-Khalili tells the story of one of the greatest scientific discoveries ever: that the material world is made up of atoms.
