Memory

This morning while biking I remembered the nice way to keep dates, number phones and even very long numbers in mind.
in 1879, Abbe Moigno created a fancy way to keep >99 decimals of PI number in mind : by creating a small text where each syllable (sound) means a number.

The rest is essentially in French and I won't try to make the same for other language. But you get the picture. I am pretty sure you can do it ;-)

will lead to the following :

Maints terriers de lapins ne gèlent = 3 1 4 1 5 9 2 6 5
Ma loi veut bien, combats mieux, ne méfaits! = 3 5 8 9 7 9 3 2 3 8
Riants jeunes gens, remuez moins vos mines 4 6 2 64 3 3 8 3 2
Qu'un bon lacet nous fit voir à deux pas=7 9 5 0 2 8 8 4 1 9

This technique is based of the following rule (again, I do it French-minded... 'Ne', 'Te'...) :

• C/'Se'/'sss' = 0;
• 'Te'/'De' = 1;
• 'Ne' = 2;
• 'Me' =3;
• 'Re'=4;
• 'Le'=5;
• 'Che'/'Je'=6;
• 'Ke'=7;
• 'Fe'=8;
• 'Pe'=9

In order to keep in mind this rule, you can learn this little sentence:

"Sot, tu nous ments, rends le champ que fit Pan"

.0....1..2....3......4.....5..6.....7...8...9

For example, if you want to learn dates, you can do the following. An example from Wikipedia's page about this :

"Rome est batie entre sept COLLINES"

...........................7..5.2

Rome got created at 752 BC
