The system works with a set of connected gears with a moving ratio of 1 to 10. In other words, if the first gear makes 1000 revolutions, then the second - 100, the third - 10, etc.

Blogger Daniel de Bruin was born just over thirty years ago. If you translate the years into seconds, it turns out that Daniel is more than one billion seconds old. In honour of this special date, he created a unique transmission system that shows the actual size of large numbers.

Googol is a number that can be imagined as one with one hundred zeros. In practical mathematics, it is nearly never used - it is too large for them to be able to measure anything. To reveal how much it is, Daniel assembled a system of connected gears, and for the last one to make only one revolution, the first one needs to activate the ‘googol demonstrator’ once.

The idea of assembling such a mechanism is fascinating, but it's not possible to activate it: as all human life is not enough to make such a vast number of revolutions. Another option is to enable the device using a powerful motor. Worries that the gears will just come into disrepair and the treasured ‘googol demonstrator’ will never be counted.
