The code that refused to die

Samuel Morse and Alfred Vail created this code in the 1830s–40s for the telegraph — the first time in history a message could travel faster than a horse. Nearly two centuries later, it still has active users.

• SOS is not an abbreviation: it was chosen because the pattern ···−−−··· is unmistakable through noise — three short, three long, three short.
• Timing rules: a dash is three times a dot; letters are separated by a pause, words by a longer one. That is why well-formed Morse is readable even at high speed.
• Still in use today: amateur radio operators worldwide, aviation navigation beacons (identifying Morse letters), assistive technology for accessibility, and emergency signaling with a flashlight.
• Learning it: most people learn by sound, not by reading — 10 minutes a day of listening practice builds the reflex in a few weeks.

The letter frequency wisdom is baked into the code itself: the most common English letter, E, is a single dot — the shortest possible symbol. Old engineering, still elegant.
