Mnemonic techniques

Psychologists believe that the less mnemonic techniques, that is, the "memorizing" rules associated with the subject of memorization, the better they are retained in memory. In other words, you do not want to, but remember. This can be shown on several merry examples.

1. The colors of the rainbow. Almost all students know a mnemonic device for remembering the order of flowers in the rainbow: "Every Hunter Wants to Know Where the Pheasant Sits" - red, orange, yellow, green, blue, blue, purple. But they say that the French schoolchildren use an even more convenient mnemonic reception, which in the Russian translation sounds like: "As Once Jacques Zvonar City Broke Lantern".

2. The number "e". One student knew the value of the number "e" (the basis of natural logarithms). To the question: "How did he remember it?" - the answer was: "It's very simple. Write 2,7 and two times Leo Tolstoy "(that is, the year of Leo Nikolayevich's birth - 1828).

3. The number of "pi". For him, there are many mnemonic techniques. But one schoolboy from Krivoy Rog came up with a new trick: "In order not to be mistaken, we must correctly read - 3, 14, 15, 92 and 6"!

4. The Morse code. When studying the Morse code, sometimes use as an mnemonic method an alphabetical list of cities compiled according to a special law: ABO, Bessarabka, etc. In the names of these cities, the number of the letters "a" is equal to the number of points, and the number of other vowels is the number of dashes in the the first letter of the city name.

5. The order of sharps and flats. One adult, who had long ago forgotten how to play the piano, told how the teacher of music forever inflicted on him the order of sharps and flats in a musical key. "Once upon a time there were two Spaniards," the teacher said. - One, tall and thin, and called him Fadosol Rehlisi (these are sharans of fa-do-salt-re-la-mi-si) and another, low and fat, and called him Similare Soldof (and this is the order of flats of the Si-mi- la-re-sol-do-fa)".

6. Formula of Modui-Napier. In conclusion, we propose mnemonic techniques for memorizing the Modui-Npere formulas for solving rectangular spherical triangles.

We need to remember that

elements need three,

where the cosine inside

(The "cosine of the middle element").

There are cotangents around.

Far cosine where needed

(The "cosine of a separately lying element").

a sinus with a sinus is friendly there.
