"What hath God wrought" — First telegraph message, May 24, 1844
The timing of Morse code is elegant: a dash is three times the length of a dot.
The space between symbols is one dot. Between letters is three dots. Between words is seven dots.
SOS - International distress signal (not an acronym)
AR - End of message
SK - End of contact / signing off
BT - Break / new paragraph
Error - 8 dots indicates a mistake
