Seriously, how geeky is knowing Morse code? But I seemed to have trouble with it. I could memorize some of the dots and dashes, but could never get any speed going. And without speed you can’t get your ticket.
Instead of simply learning the dots and dashes, this binary tree helps you start and build dots and dashes until you get to the letter you want.
Really cool, eh? (No Canadian spoken here, but “eh” was the right word to use.) And “binary tree” makes it that much geekier!
