TIL - Light Amplification by Stimulated Emission of Radiation

That reminds me, so is SCUBA, RADAR and MODEM...I miss the old History Channel shows, especially Modern Marvels

SCUBA: Self-Contained Underwater Breathing Apparatus (Blew my mind for some reason when I learned that)
RADAR: Radio Detection and Ranging (I've watched alot of WWII documentaries)
MODEM: Modulation Demodulation (I've worked in tech)
