"So the legendary wizard named Isaac was hit in the head by an apple and discovered the existence of gravity?" Harrov asked curiously.

"Yes, it is said that Lord Isaac was only a formal wizard at that time, and after an academic discussion about the movement of the stars, he suspected that there must be an invisible force pulling the planets in the galaxy around the sun, until he came to the bottom of the apple tree and was hit by a falling apple, and he came to his senses......" Lynn explained with a headache.

I don't know what went wrong, on the way back from the airship, Haroff suddenly became very interested in the fictional legendary wizards of the [Arcane Society], and as a last resort, Lynn had to tamper with some celebrity stories to fool the past.

But Haroff was clearly unaware of this, and was immersed in the celebrity stories that Lynn told.

What surprised him the most was that when the legendary wizards of the [Arcane Society] studied many magical theories, they were only apprentices, official wizards, and even ordinary people who couldn't do magic, but according to those sparse and ordinary phenomena, they relied on Olympiad mathematics, amazing intuition, and extraordinary imagination to discover the truth contained in them.

For example, Isaac discovered the phenomenon of gravity because of a falling apple, and for example, the planet under his feet was judged to be a sphere Kepler based on the phenomenon of a lunar eclipse.

Maybe that's genius!

Harrov couldn't help but think that after he became a great wizard, due to the increase in magic power and computing power, when he released magic, he caused a certain spatial disturbance, and thus discovered the existence of gravity.

Compared with the experience of those legendary wizards, Harrov couldn't help but feel a little ashamed.

But at the same time, Harrov also noticed a very important point, that is, the Olympiad!

Whether it is the three laws of the stars mentioned by Lynn, or the law of gravitation, or even the calculation of planetary data, it can be intuitively displayed in the form of Olympiad numbers.

Many complex explanations are simplified, and as long as there is a formula, it can be calculated.

Harrov called it Olympiad thinking!

This is undoubtedly something that the Wizarding Lands lacks, and perhaps it is the reason why the Arcane Society has been able to advance by leaps and bounds in the study of magic.

Thinking of this, Haroff implored Lynn to compile some basic knowledge of the Olympiad into a book, and he was ready to apply to the council to make the Olympiad a mainstream subject for all schools to study.

Lynn was gladly agreed, he had long wanted to unify all the messy operation symbols in the wizarding land, so that he wouldn't have to spend a lot of time figuring out what each symbol represented every time he looked through the magic book.

The most hateful thing is that sometimes each school of thought has different notation for the same formula, for example, there are several π representing pi, which makes his head bigger.

"Now that we've figured out the data on the planet under our feet, can we tell me what that gravitational constant is?" Harrov asked curiously.

Lynn's previous pendulum experiments and planetary calculations are undoubtedly preparing for this most important thing!

"Lord Harrov, I'm afraid you'll have to wait a few more days, and if you want to calculate the gravitational constant, there is still a very important thing missing, and then we can all intuitively 'see' the effects of gravity and space being distorted." Lynn explained with ease.

"Oh?" Harrov was immediately interested.

Gravity is an invisible and intangible force that he can only compare to water waves in order to understand the changes in space, but Lynn says that there is a way for them to 'see' the action of gravity, and this does not make him curious.

"Is there anything we can do to help?" Harrov hurriedly asked.

"I'm looking for a few ingredients for experiments." Lynn gave a general description of the appearance and nature of quartz and feldspar.

The method he used to calculate the gravitational constant was, of course, the famous Cavendish torsion scale!

To replicate this experiment, you need to use light and a few mirrors to reflect it!

After all, the influence of gravity is very weak, and only by using light projection to amplify the subtle disturbances can the changes be perfectly presented.

Quartz stone and feldspar are the two raw materials used to make glass.

Of course, it is not impossible to melt the sand directly at high temperature, but in addition to silica, the sand will inevitably be doped with many impurities, which will affect the quality of the finished product.

In addition to this, fluxes such as limestone and soda ash are also needed, these two things are still very easy to get, limestone is everywhere near the harbor of Iyeta, and soda ash can be synthesized by itself.

……

The council moved faster than Lynn had imagined, and the day after he returned to Greenriel, Harrov sent dozens of camels to transport tons of quartz sand and feldspar and piled them high in front of the temporary shelter, causing crowds to watch.

"Lord Lynn, if the quantity is not enough, I will have someone get another batch tomorrow." Krol said in a very respectful tone.

As a disciple of Harrov, Krol did not dare to underestimate this young wizard who had become famous in the land of wizards, and he was not dissatisfied with the fact that the other party had won Harrov's appreciation, after all, Theresa's fate was a warning.

"That's enough, it's definitely enough!" Lynn looked at the quartz sand and feldspar piled up into two small hills, and the corners of his mouth couldn't help twitching, with so many raw materials, he had no problem opening a glass factory!

After refusing the other party's offer of help, Lynn asked Lydia, Darren and other halflings to take some of the ingredients and return to the house.

The melting point of quartz sand is 1750 degrees, but the melting point of soda ash and limestone is reduced a lot, and it is no problem for Lynn to create this level of high temperature with magic.

Under the curious gaze of Lydia and others, the decomposed granular quartz sand gradually melted under the effect of fire magic, turning into a red liquid shape that continued to circulate in the palm of the hand, and then put it into the round mold that had been made long ago.

Once the glass was completely formed, Lynn applied tin foil to one side and poured mercury over it.

Mercury is a liquid metal that dissolves tin so that it clings tightly to the glass plate, and when it is completely solidified, a smooth glass mirror that clearly reflects the human figure is presented to everyone.
