(Phys.org) -- The famous physicist Niels Bohr first conceived of the notion of quantum jumps, or quantum leaps, in 1913. Bohr understood quantum jumps as objective events in which an atom emits or absorbs a photon, causing an electron to jump from one energy level – or quantum state – to another inside the atom.

Intel has revealed a radical transistor design called 3-D Tri-Gate that it will use in its upcoming Ivy Bridge CPUs. Great news for tech geeks, but what does that string of code words mean for your gadgets?

How does a nuclear reactor work? Most nuclear reactors, including those at Japan's Fukushima Daiichi generating station, are essentially high-tech kettles that efficiently boil water to produce electricity. They rely on harnessing nuclear fission--the splitting of an atom into two smaller atoms, which also yields heat and sends neutrons flying.
