A machine of 100 gears clearly shows "googol" - the number of all atoms in the universe

YouTuber enthusiast Daniel de Bruin recently celebrated an unusual date - more than 1, 000, 000, 000 seconds have passed since his birth. That is, a little over 30 years, although accuracy is not very important here. In honor of this event, he designed and built a "googoldemonstrator" - a transmission system that must be activated more times than there are atoms in the universe in order to get a single turn at the exit.

The googol number is very simple - it is 1 followed by one hundred zeros. And at the same time, it is so great that there is nowhere to apply it, except for mathematical paradoxes. It is believed that the number of atoms in every star, planet, asteroid, interstellar dust and other space objects, both already discovered by astronomers and as yet unknown, although very large, is less than googol. But we cannot actually count all these atoms, but we can show the googol "live".

Da Bruin's machine is extremely simple - in fact, it is a set of gears that are connected to each other to work with a ratio of 1:10 between each pair. This means that if you turn the first gear 10 times, then the second attached to it will make exactly one revolution. If we turn the first 100 times, the second will make 10 turns and transfer the force to the third to perform 1 turn. And then simple calculations show that with the number of gears of 100 pieces, you need to turn the first googol in the row once so that the last one makes a single turn.

For all the elegance of the solution, such an installation has a fundamental drawback - no one will ever see the results of its work. Even if de Bruin himself, from the moment of birth (1 billion seconds), had rotated the mechanism at 1 revolution per second all his life, he would have set in motion only the 9th level of gears in his car. This is 30 years without food, sleep and privacy. It goes without saying that a solution in the form of a high-speed motor, which produces thousands, or better millions of revolutions per second, suggests itself. But then there is a high probability that the gears will simply wear out and rub off into dust before the coveted googol is counted.
