Mnemonics is not a good way to learn the digits of things like the natural logarithm (e) or pi. I can recite pi to a thousand decimal places, and e to around 720 or so, and I did not use any special methods other than my memory.

Memorising e is quite easy; Here is a guide for only the first 15 decimal places of e ...

e ≈ 2.718281828459045 (to 15 decimal places)

We all know e as approximately 2.7 (or 2.71). The next bit is simple ... 1828 twice. That's all it is. Two-point-seven ... one-eight-two-eight-one-eight-two-eight. Next are the angles of a perfect right-angled isosceles triange ... 45° 90° 45°, in that order precisely. Say that now.

There is actually a factual piece of text for memorising fifteen digits about a president of some country elected twice in 1828 (true story!). I posted it in an 'e' thread in the This Is Cool forum a while back. A year ago I also posted links to pi mnemonics for those who want to memorise pi, for .... whatever reason?
