As long as I could transform more creatures, study their ability to perceive light, and even dissect them to find the so-called photoreceptor cells, and write a summary report, wouldn't I get the Morning Star Medal?

"If I had known earlier, I would have specialized in shaping!" Alok said with a sigh. He was better at elements and alchemy, and his shaping was just barely passing.

Unfortunately, the Morning Star Medal, which is the easiest to obtain, is about to be lost to me! However, Peirce, who is proficient in plastic science, is also extremely worried. Looking around, he knows that there are too many people competing for this medal. In a few weeks, the relevant magic theories will fill the parliament, and it may not be his turn.

Glenn and others on the platform looked at each other in bewilderment. They had no knowledge of plastic surgery, and it would be difficult for them to catch up with others in the study of invisible light.

Lin En also took into account the enthusiasm of non-Shape School wizards for optics, and after a pause, he continued, "In addition to looking for invisible light, you can also start research from another aspect... such as measuring the speed of light!"

Measuring the speed of light? Raphael and the others were stunned for a moment. There were naturally many people interested in something as omnipresent and magical as light, but they could not sense the "light element", so it was difficult to observe and measure it.

More than a decade ago, the legendary Speaker Aurora conducted an experiment in which she placed a wizard one kilometer away from herself, and then used magic to reflect light to the other person, and measured the speed of light based on the time it took to arrive.

However, this thing is so fast that even the legendary wizard's reaction speed cannot detect this tiny difference. In the end, the legendary witch could only guess that the speed of light may be more than one thousand kilometers per second, and it needs to be measured from a farther distance.

But this leads to the second problem, that is, light will scatter, and the distance will cause the transmitted light to become weaker and weaker, and it is impossible to make a more accurate measurement... so that some people doubt that light arrives instantly! However, this experiment did have an unexpected gain, that is, it was successfully measured that the propagation speed of sound is between 300 and 400 meters, and it will fluctuate according to different regions...

Sanchez explained to Lynn in detail the experiment that Speaker Aurora had done to measure the speed of light.

One kilometer? It was indeed too close, and without more professional equipment, it was normal for it to fail...

Lin En doesn’t know the exact speed of light in this world yet... but it is definitely not slow. According to the data from his previous life, a distance of one kilometer is only a few hundred thousandths of a second. Even a legendary wizard cannot measure it simply by reaction speed.

Lin En pondered for a while and looked at the wizards at the seminar. "I have some ideas about measuring the speed of light, but I haven't verified them yet. It will take a few days to prepare, probably after the seminar, and the possibility of failure cannot be ruled out. During this time, if anyone can accurately measure the speed of light, I will propose to the parliament to award him a Silver Moon Medal!"

"Silver Moon Medal? Master Lin, isn't this too exaggerated?" Sanchez interrupted quickly.

There are two conditions for issuing the Silver Moon Medal. The first is to propose a theory that is sufficient to change a mainstream magic system.

At the last seminar, when Lin En proposed the law of universal gravitation, they had planned to award him a Silver Moon Medal.

It was only because the legendary Speaker Harrolf overcame all objections, and Lin En calculated the various speeds of the planets under his feet, and proved through experiments that the planets were constantly rotating and revolving around the sun, which overturned everyone's view of the world. Only then did he receive the more glorious Corona Medal! The second method is to make a significant contribution to the Wizarding Land or the Parliament.

"I don't think this is an exaggeration. A legendary wizard in the [Arcane Society] once said that compared with optics, existing magic theories can only be described as simple or even crude. It is just an explanation of macroscopic phenomena, while optics is one of the most important keys to uncovering the real microscopic world!" Lin En said solemnly.

The speed of light is different from the speed of sound, air resistance, gravity, etc., which change when you move to another planet.

The same properties as it include the gravitational constant that Linn had previously measured, as well as the absolute zero, Hubble constant, Planck constant, etc. that have not yet been measured...

These values ​​are not limited to just one planet, but are the laws that govern objects throughout the universe... at least within the visible and cognitive range of humans, they are unchanging!

The speed of light is particularly important, and many famous formulas are inseparable from this constant!

One example is the famous mass-energy equation – E=mc^2!

The E on the left represents energy, the m on the right represents mass, and c is the speed of light. This formula contains the secret of mass and energy conversion. Whether it is a nuclear explosion or the more powerful antimatter annihilation, it can be calculated using this formula! Of course, whether the theory of the constancy of the speed of light is universal in the world is still a question mark, and all of this needs to be verified by experiments.

Lin En has always wanted to calculate these basic constants, but he had focused most of his energy on the war in the kingdom, which had delayed it.

It can be said that it was only when they began to study optics that they uncovered a corner of the real world, from the orderly macroscopic world to a chaotic and strange microscopic world.

Even though the Federation in the previous life was not able to fully study quantum theory, even a small gain would be enough to accomplish such a feat as interstellar travel...

Lin En's overly straightforward words made the wizards present feel a little difficult to accept. The wizarding land has developed magic for hundreds of years, but the other party described it with just one word: simple and crude. It was really sensational!

“Could it be that this legendary master of the Secret Law Society went insane while studying light?” A great wizard in the audience sneered and said, very dissatisfied with Lin En’s words that belittled the existing magic theory. Although the element of light is magical, it is at best just one of the bricks and tiles that make up the magic building…

The theory of light elements in the wizarding land has gone through decades of development and improvement and has already built a general framework, but it has not yet undergone final verification.
