|Nick Holonyak, Jr. demonstrates the world's first visible light-emitting diode (LED) to General Electric suits, changing the world of lighting forever. Holonyak later said that the LED would replace incandescent lights. It's just taking a little bit longer than expected. In 1977, Holonyak's team also demonstrated the first quantum well laser. You can find this low-power, concentrated laser in CD and DVD players. Now LEDs are in myriad devices, from the latest flashlights to the HDTV in your living room. And while the incandescent light bulb still burns brightly in many homes, its days are numbered. Government regulation and the falling cost of LEDs, which continue to glow brighter every year, are nipping at Edison's baby. Holonyak was right. It just took a few decades for everyone else to catch up.|
