Robert Krampf or thehappyscientist demonstrates in this video how we can use our cell phone to see colors normally invisible to our sight and shares some other nifty tricks with his remote control.
You may be surprised to learn that the first person to conceive of the remote control occurred in 1893 by Nikola Tesla in U.S. Patent 613809. During world war one German scientists exploited this patent and were the first to invent remote controlled motorboats. The first popular consumer use, however, emerged with remote controlled garage doors in the late 1940’s.
But radio Engineer Eugene Polley of the Zenith Radio Corporation is credited with creating the first wireless TV remote that could mute the sound and he worked in collaboration with Dr. Robert Adler who is attributed with the invention of the first commercial production in 1956 of the TV Remote Control who designed The Space Command based on ultrasonics.
