Useful and interesting information about the simplest mathematical calculations in this field are in the books in elementary mathematics, like the book Sawyer , or in books about how to image calculations, such as in Schmid . We all know, however, that there are factors that keep this development in a certain framework. Capital, placed in the bank, does not rise to unlimited size, despite the fact that the curve of compound interest on capital is continuously crawling up. None forest fire never destroyed all the forests of the earth. There is a well-known and very important Le Chatelier's principle, according to which development itself creates constraints for themselves. This principle was first developed in relation to the natural sciences, and later extended to the area of ??Social Sciences. For example: 1) Unlimited population growth in a particular area creates overcrowding, hunger, disease, which in turn inhibit the further growth of the population. 2) The continuous increase in prices leads to a reduction in sales, increase in the number of products, which in turn slows down the rise in prices. Action Le Chatelier's principle, which is expressed in the fact that the rising curve gradually becomes horizontal direction or even goes down, especially noticeable in the later stages of the movement on the uplink.
