   "So the legendary wizard named Isaac discovered the existence of gravity after being hit in the head by an apple?" Harov asked curiously.

"Yes, it is said that Sir Isaac was just an official wizard at that time. After an academic discussion on the movement of stars, he suspected that there must be an invisible force that was pulling the planets in the galaxy to revolve around the sun until they left. When he was under the apple tree, he was hit by a falling apple, and he woke up..." Lin En explained with a headache.

I don't know what went wrong. On the way back in the airship, Harov suddenly became interested in the fictional legendary wizards of the [Secret Society], and as a last resort, Lin En had to tamper with some celebrities' short stories. Stories, easy to fool the past.

   But Harroff obviously didn't know this, and was immersed in the celebrity stories told by Lynn.

What surprised him the most was that when the legendary wizards of the [Secretary Society] researched many magical theories, they were still apprentices, official wizards, or even ordinary people who could not use magic. Rely on the mysteries, amazing intuition and extraordinary imagination to discover the truth contained in it.

  For example, Isaac, who discovered the phenomenon of gravity because of a falling apple, and another example, judging from the phenomenon of lunar eclipse that the planet under his feet is a spherical Kepler.

   Maybe this is genius!

   Harov couldn't help thinking that after he became a great wizard, he discovered the existence of gravity because of the increase in magic power and calculation power. When he released magic, he caused a certain disturbance in the space.

  Compared with the experience of those legendary wizards, Harov couldn't help feeling a little ashamed.

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

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

   Simplifies many complex explanations, and can be calculated as long as there is a formula.

  Harov called it Mathematical Thinking!

   This is undoubtedly something that is lacking in the land of wizards, and it may also be the reason why the [Secret Society] can make rapid progress in the study of magic.

  Thinking of this, Harov begged Lynn to summarize some basic knowledge of Mathematical Olympiad into a book. He was going to apply to the parliament to make Mathematical Olympiad a mainstream subject for all schools to learn.

Lynn naturally readily agreed. He had long wanted to unify all the messy arithmetic symbols in the wizard's land, so that he would not need to spend a lot of time figuring out what each symbol represented each time he read the magic book. wearing something.

  The most abominable thing is that sometimes each school of thought has different operation symbols for the same formula. For example, there are several π representing pi, which makes his head big.

   "Since we have calculated the various data of the planet under our feet, can you tell me what the gravitational constant is?" Harov asked curiously.

  The pendulum experiment and calculation of the planetary data that Lynn made before are undoubtedly preparations for this most important thing!

"Master Harrov, I'm afraid you still need to wait a few more days. If you want to calculate the gravitational constant, there is still a very important thing missing. At that time, we will all be able to intuitively 'see' the gravitational force and the distortion of space. Influence." Lynn explained freely.

   "Oh?" Harov immediately became interested.

Gravity is an invisible and intangible force. He can only compare it to water waves to understand the changes in space, but Lin En said that there is a way for them to 'see' the effect of gravity. He was curious.

   "Is there anything we can help with?" Harov asked hastily.

   "I'm looking for several raw materials for experiments." Lynn gave a rough description of the appearance and properties of quartz stone and feldspar.

  The method he used to measure the gravitational constant is naturally the famous Cavendish torsion balance!

  If you want to reproduce this experiment, you need to use light and a few mirrors to reflect light!

  After all, the influence of gravity is very weak. Only by using light projection to amplify the subtle disturbance twice can the changes be perfectly presented.

   Quartz stone and feldspar are two raw materials for making glass.

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

   In addition, fluxes such as limestone and soda ash are needed. These two things are still easy to get. Limestone is everywhere near the harbor of Iyeta, and soda ash can be synthesized by yourself.

The actions of the council were faster than Lynn had imagined. On the second day after he returned to Greenriel, Harov sent people to transport the quartz sand and feldspar weighing several tons with dozens of camel beasts. They were transported over and piled high in front of the temporary residence, attracting crowds of onlookers.

   "Your Excellency Lynn, if the quantity is not enough, I will send someone to get another batch tomorrow." Koror said in a very respectful tone.

As a disciple of Harov, Koror did not dare to underestimate this young wizard who had risen to fame in the Land of Wizards, nor was he dissatisfied because the other party was appreciated by Harov. After all, Teresa's fate Just a warning.

   "Enough, this is definitely enough!" Lynn looked at the quartz sand and feldspar piled up into two small hills, and the corners of his mouth twitched. With so many raw materials, he can open a glass factory without any problem!

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

The production process of glass is not complicated, it only needs to be dissolved at high temperature. The melting point of quartz sand is 1750 degrees, but adding soda ash and limestone lowers the melting point a lot. Using magic to create such a high temperature is not enough for Lynn. Words are still okay.

Under the curious eyes of Lydia and others, the decomposed granulated quartz sand gradually melted under the action of flame magic, turning into a red liquid shape that circulated continuously in the palm of the hand, and then put it into the circle that had been prepared earlier. inside the mold.

   Once the glass was fully formed, Lynn put tin foil on one side, and finally poured mercury.

  Mercury is a liquid metal that can dissolve tin and make it stick tightly to the glass plate. After it is completely solidified, a smooth and flawless glass mirror that can clearly reflect the shadow of a person is presented in front of everyone.
