Shi Xiong knew exactly what these alchemists of this era wanted most.

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

Almost everyone who can become an alchemist is extremely determined and never talks about failure lightly.

It’s as if the four alchemists under his own hands have spent several years in the New World as a contract slave life comparable to hell, and the Jack in front of him has his legs broken by the nobles, but even In this way, none of the four of them said that I would quit, that I would go home.

For them, the unknown and full of mystery alchemy is the supreme path they pursue.

As long as they can be given some pointers on alchemy, which is the germination of modern science, they will definitely abandon everything and follow them without hesitation.

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

Just like Jack Williams, this guy has a fanatical pursuit of mechanics. Of course, this aspect is not called "machinery industry" in this era, but collectively called "alchemy".

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

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

The alchemists of this era, or "sprouting scientists", have a passion and enthusiasm for investigating the unknown, which people of later generations cannot understand.

That's why Shixiong proposed gear transmission to Jack Williams.

Whether it is East or West, the application of gears in transmission appeared long ago.

But because there is no corresponding scientific theory, the application of gears in transmission was not popular before the seventeenth century.

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

It is worth mentioning that the Felipe de la Hill who put forward this theory is also an alchemist...

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

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

It was not until another mathematician Savari developed the famous Euler-Savari equation on the basis of Euler's theory that the application of gears in transmission was completely opened.

The reason why Watt's improved steam engine can be promoted on a large scale is also because the Euler-Savari equation solves the problem of gear application. Otherwise, the steam engine will appear, but it will not be able to achieve effective transmission. The steam engine is just a decoration.

Therefore, at this time, before the Euler-Savari equation appeared, the gear transmission method was almost equivalent to a magical technique for a mechanical research fanatic.

In the past, Shi Xiong studied this theory when he was in college. Later, after going to work, there were also several machinery and equipment left by the Jiangnan Manufacturing Bureau in the museum. In order to properly maintain these precious cultural relics, Shi Xiong did not study this aspect less. Knowledge, naturally, have an understanding of gear transmission.

Although Shi Xiong is not proficient in this aspect, what he understands in this era is an out-and-out magical technique.

Just like the Euler-Vasari equation, there are also the calculation formula of gear modulus, pitch modulus calculation formula, the calculation formula of index circle diameter, etc., these formulas are popular things in later generations, even The students in vocational and technical schools have also learned these formulas, but in this era, for the alchemists in Europe, only God can know these formulas.

So, when Shixiong proposed the Euler-Vasari equation to Jack, his eyes became straight...

Because of the limitations of the times, it is not difficult to make any inventions in this era. Many inventions and creations are only derived from a single idea or a flash of inspiration. The difficulty lies in how you present the moment of inspiration.

It's like ninety-nine years ago, in 1666, when the 23-year-old Newton was temporarily closed because of the Black Death in Cambridge Trinity College where he was studying. Newton returned to his mother's house and was meditating in the garden. The apple to his head.

Although whether Newton was hit in the head by Apple at the time has not yet been finalized, it is undeniable that Newton must have been inspired by something at the time ~lightnovelpub.net~ and then he had it. The emergence of the law of universal gravitation.

If an alchemist like Jack gives him an inspiration or an opportunity for inspiration, then he may not be unable to come up with any outstanding scientific theories.

For opportunities like this, Shi Xiong has so many in his hands. At least the Euler-Vasari equation he has taken out now does not exist. For Jack Williams who is proficient in mechanical manufacturing, it is absolutely No less than the apple that hit Newton's head...

Give Jack Williams knowledge points about mechanics, and for Jean Agust, who likes pharmacology, Stone Bear naturally has a way to keep his heart.

Although the Frenchman Jean Agusta is also an alchemist, he is actually a pharmacist. He prefers to study some weird medicines.

The British alchemist Bill Gates took the path of a traditional alchemist, but compared to the French alchemist David Adion who was proficient in metal smelting, Brother Li was more interested in chemical experiments. Of course, in this era, chemistry is just a rudimentary form. Although the British alchemist Robert Boyle published a landmark book in the history of chemistry as early as 1661, "The Skeptical Chemist", and later generations also regarded this year as the beginning of modern chemistry. A word is just a noun.

But whether it was medicine, chemistry or metal smelting, Shi Xiong had a lot of knowledge of later generations in his mind. This kind of knowledge that will be learned by junior high school students in later generations is truly "God's guidance" in this age!

Therefore, Shi Xiong was more certain about keeping the four of them.
