мнемоническими правилами, но и сам придумывать новые.
310 Translation of paragraphs 1 - 25 presented above 1. «Кто и шутя и скоро пожелает(ъ) пи узнать, число уж(ъ) знает(ъ)». Remember this couplet? It doesn't make much sense even in Russian, therefore I will rather not try to translate it into English. So, is it completely useless? Wrong! 2. Of course, these 2 lines are very far away from a real poetry. But they are not designed to evoke any emotions in human hearts. On the contrary, the purpose of these lines is very prosaic, but nonetheless, it is quite possible that they will be infinitely passed on from generation to generation ... 3. The fact is that those lines allow you to easily, quickly and with very high accuracy write down a number well known in geometry: ¶ (pi), which characterizes the ratio of the length of any circle to its diameter. 4. Indeed, if we use the old spelling applied before 1918 (words ending in hard consonant had also, after that consonant, hard sign ' ъ') , we may notice that the number of letters in each word of this couplet corresponds to the respective digit of the number ¶: 3,1415926536. Would you be able to remember this number without a prompt? Most probably - no. Whereas our tip for all its apparent absurdity is easy to remember and gives the key to remembering the exact value of this popular mathematical concept. 5. The method, which we used to remember the number ¶, is called a mnemonic rule. The 311 Great Soviet Encyclopedia gives the following definition of the mnemonic: "Mnemonic (from the Greek mnemonika - art of memory) - a system of different techniques facilitating memorization and increasing the amount of memory by forming artificial associations." 6. The simplest mnemonic rules were used by people from the ancient times. For example, nicks that they left on trees helped them navigate the dense forest. On the other hand, already in our modern times, one of my friends used to pin a paper clip to the strap of his watch, saying that it helps him remember and keep the promise (for example, to take something from home and bring it to his workplace). 7. However, let us return to mathematics. With the number ¶, it seems, everything is clear. But in the higher mathematics, which is taught at universities or other higher educational institutions, people also use another notable number - number Download 3.08 Mb. Do'stlaringiz bilan baham: |
