It’s Morse Code Day! Time to use a little Morse code. If all you know is . . . _ _ _ . . . (SOS), then today is the day to learn a bit more.
In 1836, Samuel Morse, Joseph Henry, and Alfred Vail developed the telegraph, a system that sends electrical pulses along a wire over long distances.
To make full use of this invention, Morse and Vail slowly invented a special code of dots and dashes that could be easily translated into letters and numbers.
Since then, Morse code has been used for all sorts of communications over the telegraph, through casual tapping in every spy movie, and by flashing lights on ships.
Morse Code Day is celebrated every year on Samuel Morse’s birthday.
Here’s an ancient S.O.S.:
“In my distress I called to the LORD;
I cried to my God for help.
From his temple he heard my voice;
my cry came before him, into his ears.”
