Googolplex is the name of a number ten to the hundredth power, which does not describe anything properly. The American mathematician Edward Kasner invented her only to accustom his nephew to large numbers.]]> 2018-10-07 16:35:41 UTC https://padlet.com/mazaretka2006/b4bvu82jxin5/wish/290049417 mazaretka2006 https://padlet.com/mazaretka2006/b4bvu82jxin5/wish/290050601 People at a certain stage of their development came to the point when it was not enough for them to count their hands and began to help themselves with instruments. The first such device was the abacus used by the Greeks. The name comes from the Greek abax, which means the album, probably because once pebbles were placed in engraved plates or in the ground. Individual columns meant unities, tens, hundreds, etc. With the help of the abacus, they were able to add, subtract and multiply.

Abacus had many different forms. Most often they were rectangular boards with grooved grooves, in which arranged pebbles signify particular positions of the presented figure. By adding and subtracting stones in rows, arithmetic operations were performed. Roman pebbles were called calculi. As time went on, stones were made in the stones and threaded on strings. In this way, portable computing devices were created.]]> 2018-10-07 16:43:25 UTC https://padlet.com/mazaretka2006/b4bvu82jxin5/wish/290050601 mazaretka2006 https://padlet.com/mazaretka2006/b4bvu82jxin5/wish/290054341 Regular polyhedrons are solids whose all walls are congruent regular polygons and in which the same edges come out from each vertex.

For Plato, these lumps were essential, for he recognized that matter is made of integrals and is not divisible, and these entities are ideal. They are not solid bodies, but geometrical figures. The ideal simplest geometrical figure is a triangle, the plane limited by the smallest number of straight lines. According to Plato, triangles are the simplest building element, the basic brick from which Kosmos was built.]]> 2018-10-07 17:10:29 UTC https://padlet.com/mazaretka2006/b4bvu82jxin5/wish/290054341
