Test your number memory in 90 seconds.
Twelve digits, fifteen seconds, twice: once by rote, once as one silly story. See which you keep.
Hear. Build. Recall.
Hear
Every digit keeps one consonant sound for good - 5 is always "l," 2 is always "n." Ten sounds, learned once.
Build
Sounds become words, and words become one scene: 52 is LION, 44 is ROAR. Twelve digits become one silly story.
Recall
Rebuild it cold, before the answer shows - that's the actual proof.
Forge the pairs that let you remember anything.
LION and ROAR were two pairs out of a hundred, and once one story has stuck the rest come the same way.
See how numbers become pictures
The Major System in full: every digit's sound, and how to forge reusable pairs for any number, not just this story.
The next level →Pictures need somewhere to go
Memory palace: fix a route through a place you already know, park one scene at each stop, and walk it back in order.
Give them a home →What you can already remember with this.
Constants you actually need
Light covers 299,792 km a second: 29-97-92, a KNOB, a BUG, a BONE (the K in KNOB is silent, and only sounds count). "A KNOB-headed BUG gnaws a BONE" - one scene, not six loose digits.
Pi, as far as you like
Every ten digits of pi becomes five words on a route. Competitive memorizers use exactly this system.
PINs, plates, and lockers
The same two techniques work on anything with digits in it - just a code and a place to put it.
