Nobel prize for the blue LED or finding a blue light emiting superconductor

The blue LED discovery, short for light emitting diodes, has been awarded today the Nobel prize in physics today. These (in red and green) have been around since 1962, but what makes the blue LED worth the prize is that it was the missing link to be blended and generate white light. The awardees managed to produce the elusive superconductor - by growing high-quality crystals of gallium nitride - producing blue light. The disputes around the discovery, royalties and multimillionaire lawsuits is also very complex.

Now, this week looks much more relaxed here at Harvard. Last week's schedule included two colloquiums - Xi Yin and also Andy Strominger in the math department - plus Seiberg's talk. We also held the High Energy Journal Club where Xi Yin talked about classicalization in Ultra-Planckian 2->N Scattering.
