Quirky Science (4)

29.06 18:10 Dauer: 30 Minuten

DocuBox Slovak Telekom TV-Sender, (verschlüsselt über Satellit)

S01 E04

A man with an ear for music, one of the first to try teaching the deaf how to speak, thought he could build a "harmonic telegraph". He had this idea that several notes could travel through a wire simultaneously, instead of the one Morse code that the telegraph could transmit. He thought this to be possible because he misinterpreted the writings of a researcher writing in German - a language he did not know. - And would later describe his misinterpretation as a "very valuable blunder". The man was Alexander Graham Bell and he invented telephony. The big question is: what happens in that wire? How can voices travel? Bell and his assistant eventually proved that different tones would vary the strength of an electric current in a wire. In fact, it's the vibrations of the voice that determine the strength of the current.
