There was a lot of discussion in the auditorium, and the wizards who were proficient in shaping were particularly excited. Lynn and Sanchez undoubtedly pointed the direction for optical research.
As long as he transforms into more creatures, studies their ability to perceive light, and even dissects and finds the so-called photoreceptor cells, and writes a summary report, wouldn't he get the Morning Star Medal?
"If I had known, I would have gone to study Shaping!" Alok sighed. He was better at elements and alchemy, and Shaping was only at a barely passing level.
It's a pity that the most easily obtained Morning Star Medal is about to leave me!
However, Peirce, who is proficient in plastic surgery, is also extremely worried. Just look around and you will know that there are not many people competing for this medal. Otherwise, in a few weeks, the relevant magic theories will be piled up in the Parliament, and it may not be able to take turns. Get yourself.
Glenn and others on the high platform looked at each other in confusion. They had no experience in plastic surgery, and it would be difficult for them to keep up with others in research on invisible light.
Linn also took into account the enthusiasm for optics among wizards who were not from the plastic school. 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 others were stunned for a moment. There are naturally many people interested in something as ubiquitous and magical as light. However, they cannot sense the 'light element', so it is difficult to observe it. and measurement.
More than ten years ago, the legendary Speaker Aurora conducted an experiment where a wizard was one kilometer away from herself, and then used magic to reflect light to another person, and measured the speed of the light based on the arrival time.
However, this thing is so fast that even the reaction speed of the legendary wizard cannot detect this small difference. In the end, the legendary witch can only guess that the speed of light may exceed one thousand kilometers per second, and it needs to be carried out from a longer distance. Determination.
But the second problem that arises is that light scatters. If the distance is too far, the transmitted light will become weaker and weaker, making it impossible to make more accurate measurements...so that some people suspect that the light arrives instantaneously. of!
However, this experiment had an unexpected gain, that is, it was successfully measured that the propagation speed of sound is between 300 and 400 meters, and will fluctuate depending on the region...
Sanchez explained to Linn in detail the experiment that Speaker Aurora had done to determine the speed of light.
One kilometer? It is indeed too close, and there is a lack of more professional instruments, so failure is normal...
Lin En still doesn't know what the speed of light is in this world... but it's definitely not much slower. According to the data from the previous life, the distance of one kilometer is only one hundred thousandth of a second. Even for the legendary wizard Nor can it be measured solely on the basis of reaction speed.
Linn pondered for a while and looked at the wizards at the seminar. "I already have some ideas about the determination of the speed of light, but I haven't verified it yet. It will take a few days to prepare, probably after the seminar. The possibility of failure is not ruled out. During this time, if anyone can accurately If you find out what the speed of light is, I will propose to the Congress that he be awarded a Silver Moon Medal!"
"Silver Moon Medal? Master Linn, is this too exaggerated?" Sanchez quickly interrupted.
There are two conditions for issuing the Silver Moon Medal. The first is to propose a theory that can change a certain 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 just the legendary Speaker Harrov who had the power to override all opinions, and Lin En calculated the speed of the planet under his feet, and used experiments to prove that the planet is constantly rotating and revolving around the sun, subverting everyone's view of the world. Only then did he receive the even more glorious Corona Medal!
The second method is to make a significant contribution to the Wizarding Land or the Parliament.
But now it is just to measure the speed of light, not to analyze the properties of light. He feels that a Morning Star Medal is enough...
"I don't think this is an exaggeration. A legendary wizard in the [Arcane Society] said that compared with optics, the existing magic theory can only be described as simple, even rudimentary. It is just an explanation of macroscopic phenomena, and Optics is one of the most important keys to revealing the microscopic real world!" Lin En said solemnly.
The speed of light is not different from the speed of sound, air resistance, and gravity, which will change if you change the planet.
It has the same properties as the gravitational constant previously measured by Lynn, as well as the absolute zero, Hubble constant, Planck constant, etc. that have not yet been measured...
These values are not limited to one planet, but are the laws of objects that prevail in the universe... At least within the scope of human visibility and cognition, they are unchanged!
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 mystery of mass and energy conversion. Whether it is a nuclear explosion or a more powerful antimatter annihilation, you can use this formula to calculate it!
Of course, there is still a question mark as to whether the theory of constant speed of light is accepted in the world, and these all need to be verified experimentally.
Lin En has always wanted to calculate these basic constants, but he had put most of his energy into the war in the kingdom, so he kept delaying it.
It can be said that starting from the study of optics, they have opened up a corner of the real world, from the orderly macroscopic realm to a chaotic and strange microscopic realm.
Even the Federation in the previous life failed to fully study quantum theory, but even a small gain was enough to complete a feat such as interstellar voyage...
Lin En's overly straightforward words made the wizards present find it a bit difficult to accept. The magical science that has been developed in the Wizarding Land for hundreds of years was described by the other party as simple and crude. It is really a bit sensational!
"Could this legendary master of the Secret Magic Society have become obsessed while studying light?" A great wizard in the audience said with a sneer. He was very dissatisfied with Lin En's words that belittled the existing magic theory. The element of light is indeed magical, but at best it is just one of the bricks that make up the magic building...
After decades of development and improvement, the light element theory of the Wizarding Land has established a general framework, but it has not yet undergone final verification.
