Chapter 202 (1/2)

Stone bear knows very well what these alchemists of this era want most.

It is no exaggeration to say that although the alchemists of this era are not as fanatical as those in the middle ages of Europe, they are definitely not comparable to ordinary people.

Almost all those who can become alchemists are very determined and never say failure lightly.

It's just like the four alchemists who have been in the new world for several years, and Jack was interrupted by the nobles. But even so, none of them said that I would quit and I would go home.

For them, the unknown and mysterious alchemy is their pursuit of the supreme road.

As long as we can give them some guidance on alchemy, that is, the germination of modern science, then they will definitely abandon everything and follow them without hesitation.

For them, even a little progress in alchemy is their greatest affirmation.

Like Jack Williams, this guy has a passion for mechanics. Of course, in this era, this aspect is not called ”machinery industry”, but collectively referred to as ”alchemy”.

In their eyes, since other alchemy, that is, the so-called chemical and physical alchemy, can not produce the ”sage's stone”, it needs to break through from other aspects.

And the machinery industry is just another interesting industry. Once a determined alchemist like Jack Williams gets in, it's almost impossible to climb out.

The alchemists or ”budding scientists” of this era have a passion and enthusiasm for pursuing the unknown, which is beyond the understanding of later generations.

That's why stone bear gave Jack Williams a gear drive.

No matter in the east or in the west, the application of gears in transmission appeared long ago.

But because there is no corresponding scientific theory, so before the 17th century, the application of gear in transmission was not popular.

But with the French Felipe de la hill put forward the theory that involute can be used as tooth profile curve in 1694, the application of gear in transmission began to have a solid theoretical foundation.

It is worth mentioning that the person who put forward this theory, Felipe de la hill, is also an alchemist

With the support of involute theory, in 1733, another French alchemist, M. Camus, published Camus theorem, which further consolidated the foundation of gear application.

But at this time, the application of gear in transmission is still not very extensive. It was not until this year, that is, 1765, that Swiss mathematician Leonhard Euler put forward the mathematical basis for the analytical study of involute tooth profile and clarified the relationship between the curvature radius of the tooth profile curve and the position of the curvature center of a pair of meshing gears.
