An elaborate quantum dance powers LED lightbulbs. The more precisely the dance can be choreographed, the closer LEDs will come to fulfilling their promise as the ubiquitous energy-efficient lighting source of the future (LEDs are already efficient, but they could be a lot more so). My latest story, “Mathematicians Tame Rogue Waves, Lighting Up Future of LEDs,” is about a

“The rapid adoption of LEDs in lighting marks one of the fastest technology shifts in human history,” Goldman Sachs stated in a new report. The accelerated deployment of light-emitting diode (LED) bulbs is on track to save U.S. consumers and businesses $20 billion a year in electricity costs within a decade, which would lower U.S. CO2 emissions by some 100
