As part of a greater effort to someday build computing elements at an atomic scale, IBM scientists in Zurich have taken the highest-resolution image ever of an individual molecule using non-contact atomic force microscopy. Performed in an ultrahigh vacuum at 5 degrees Kelvin, scientists were able to "to look through the electron cloud and see the atomic backbone of an individual molecule for the first time," a feat necessary for the further development of atomic scale electronic building blocks.

1. Einstein showed that light travels in bundles called quanta, which are at
the heart of the light-emitting diode. When electrons in a semiconductor-based diode move from one side to another, they shift to a less excited state, releasing energy in the form of photons. Channel these, and you get a bright, long-lasting light source.
2. In 1917 Einstein demonstrated that when a photon comes into contact with an atom, it can trigger a chain-reaction release of additional photons from
