Physics: Featured Facts
Single Molecule Electroluminescence
Physics / Optics

(A) Silver oxide film exposed to DC current; (B) activated regions emitting light when conected to AC current; (C) zoom shows single molecule electroluminescence Incandescence and luminescence are two main ways of producing light. In incandescence, electric current is passed through a conductor (filament of a light bulb for example). The resistance to the cur continue reading this fact

The Early Universe Soup
Physics / Quantum Mechanics

Collision of two gold nuclei at the RHIC accelerator. An attempt to produce quark-gluon plasma in the laboratory. In the first few millionths of the second after the Big Bang, the universe looked very different than today. In fact the universe existed as a different form of matter altogether: the quark-gluon plas continue reading this fact

Earth's Magnetism
Physics / Magnetism

Front page of the William Gilbert's book ' De Magnete' from 1600. Most ancient civilizations were aware of the magnetic phenomenon. Sailors in the late thirteenth century used magnetized needles floating in water as primitive compasses to find their way on the sea. continue reading this fact
