Mentalist acquires and provides memory techniques for remembering numbers and word lists.

The mentalist uses a technique called the Major System.  To remember numbers, substitute these sounds, then make a word from the sounds.

This mnemonic system is based on the substitution of sounds with digits. With this technique you can represent words by numeric sequences. Since remembering words is far more easy than numbers, this system can be used to easily remember numerical sequences, like telephone numbers or year dates. For the number you want to remember you find corresponding words which you turn into a catchy story. The made up story should be very unusual so it sticks.

To get the numerical representation of a word you have to follow a few rules. You should be very good at remembering those rules, so you can translate your story quickly back into the actual numbers. This task should not be underestimated!

• Consonants get substituted by the table.
• Vowels and the letters w, h, y and x are ignored.
• Double letters are disregarded. So ss equals 0.

Here are a few ideas how to use it:

• Remember birthdays and year dates
• Mnemonics for phone numbers
• Recall Credit Card numbers and pin codes
• Magic tricks with numbers, like reproducing unusual many figures of π

Thinker can express his thoughts.
