Apr. 20, 2011 — Did the early universe have just one spatial dimension? That's the mind-boggling concept at the heart of a theory that University at Buffalo physicist Dejan Stojkovic and colleagues proposed in 2010. They suggested that the early universe -- which exploded from a single point and was very, very small at first -- was one-dimensional (like a straight line) before expanding to include two dimensions (like a plane) and then three (like the world in which we live today).
Universe Sandbox is an interactive space simulator for Windows based PCs. Unlike most astronomy software that just shows you what the sky looks like or where the planets are, Universe Sandbox is a powerful gravity simulator.

The theory behind the substance graphene was first explored by theoretical physicist Philip Wallace in 1947 as kind of a starting point when he was doing research trying to understand the electronic properties of more complex, 3D graphite. although the name graphene wasn't actually coined until 40 years later, where it was used to describe single sheets of graphite. In other words, it's the name given to a flat monolayer of carbon atoms that are tightly packed into a 2D honeycomb lattice; like a molecular chicken-wire that is one atom thick. It's essentially the basic building block for graphitic materials of all other dimensionalities; it's a stepping stone to building bigger things.

If you haven’t seen MakerBot’s 3D printer in action, you’re missing out. The $1225 MakerBot Thing-O-Matic is a humble, almost DIY, looking device that can “print” objects up to 4x4x6-inches large automatically after you give it the necessary instructions and a spool of plastic.
Structure of the Universe Does the Universe have an edge, beyond which there is nothing?
Albert Einstein’s greatest scientific “blunder” (his word) came as a sequel to his greatest scientific achievement.
If the popular misreading of Mayan mythology is correct, we have fewer than two more years left on this Earth. That leaves precious little time for the tech industry to develop and perfect of all the cool technologies that sci-fi authors have dreamed up over the years. Still, while a December 2012 apocalypse may spell doom for the commercial viability of hovercars, it doesn't mean that the next couple of years in tech will be dull — quite the contrary. 2011 is already shaping up to be a banner year for tech and web innovation.
Among the unsolved mysteries confronting 21st century physics from gravitational waves to dark energy, neutrinos -the "ghosts of the cosmos"- are near the top of the list.
