Orange LED in Liquid Nitrogen [Video]

We submerge an orange LED into liquid nitrogen which causes the LED to change colour from orange to yellow and towards green. So geeks, can anyone here explain exactly why the light emitted by the LED changes color when submerged in liquid nitrogen? If you do, let us know the explanation in the comments section […]

Higgs Boson Confirmation Now One Step Away

The particle is currently officially labeled as Higgs-like, referring to its similarities to an imaginary particle described by physicist Peter Higgs among others. His model (in very simplified terms) […]
