However, I've always found it easier to simply remember the decimals themselves rather than some obscure sentence. I remember a little over 50 decimals of pi, 20 of e, 8 of r, and 5 each of the logarithm (base 10) of the nine digits. Anything else, I now use a calculator.

The trick that worked for me is to repeat them out loud many times a day for about a month. I remember the sound, not the actual numbers (meaning: I have to repeat the entire number from the start even if I only need, let us say, the 15th decimal).

In the same way, I've always found it easier to remember a formula or a list directly, rather than a mnemonic.

The only exception:

OH! Be a fine girl. Kiss me right now, sweetheart.

(The spectral classes of stars on the main sequence, starting from the hottest stars: O B A F G K M R N S -- the reason for the "chaotic" order is that the original definitions based on spectral lines were retained: A B C D E F G... but the order was rearranged in order of temperature instead of the strength of spectral lines).

Answer 2

3.1415926535

"Man, I need a drink, alcoholic of course, after ten digit (memorizations)."

The digits are the number of letters in each of the above words. (I threw in one more word to make it a complete sentence, but it doesn't work with the next digit.)

Answer 3

There are none. It shouldn't be too hard to memorize up to 10 decimal places.
