This is intriguing, can you describe in more detail how you map a series of numbers to a shape/sound? like is 1234 a slope / ?
Yes. In fact there's almost no "entropy" to remember in 1234 because it perfectly matches a 45 deg slope. I just have to remember it starts at ground and has length 4. A seq like 1244 has a bit more entropy with the "bump" where the 3 should be, so it's easier to see it as a slope of length 2 starting at 12, or some "busy-beaver" like sequence that starts gradual and curves rapidly up to 44. The bump at 3 seems most…
I can totally understand what you're saying but there's no way I could apply it to a series of numbers, maybe not even if I practiced.
Did you always have this feeling with numbers, or was it practiced at all? It feels like what you're describing is a natural visualization you've developed and it also sounds a lot more powerful than something one might practice.
