Greetings, Mister Principal: Within the light cone

It only takes a genius to remember the address of this website: (Dianping Chinese), the fastest update! No ads!? World line? Light cone?

After so many years of becoming a high-level mage, Broly Augustine felt for the first time that he could not keep up with the progress. Although Reiner's statement and the moving light point demonstration were very intuitive, it was difficult for Austrian to keep up with the progress. It was still difficult for Gustin to accept a new concept so quickly.

"Simply put, your Excellencies, if we can clearly know where a particle is now and its trajectory, then we can naturally deduce where it will be at any time in the past, present and future. , these positions are connected to form a line, which is the world line of this particle. The world line points from the past to the future, and the specific coordinates are presented in real space."

Seeing that everyone was still a little confused, Reiner drew a three-dimensional rectangular coordinate system. A point started from the origin and moved in one direction, showing a clear trajectory.

“For the convenience of understanding, we can not discuss the situation of real space and assume that there is a two-dimensional world with only a plane.”

With a wave of Reiner's hand, the three-dimensional rectangular coordinate system suddenly became a plane rectangular coordinate system. A point moves in the plane and draws a curve.

“If we change the original vertical axis Z to time, then the trajectory of this point will show three-dimensional characteristics, and this will also appear in the three-dimensional coordinate system, but the axis of time is not what we see visually. ”

"You mean high-dimensional space?"

Mr. Braggs looked at Reiner's demonstration and said in a low voice.

"It can be understood so simply, Mr. Braggs. In fact, I prefer to call it Iain Gray space, because it is not simply a space with one more dimension than length, width and height, but is composed of time and space. time and space."

Reiner smiled, and then he carried out relevant calculations and demonstrations, deriving in detail the Inglen space and the way the world line is presented in the Inglen space.

"This could be a whole other paper, Reiner."

After listening to Reiner’s derivation, President Dmitry nodded slightly.

"Ingle space is not an independent theory, but knowledge that is closely integrated with the theory of relativity. I thought you only solved the problem of the speed of light, but I didn't expect that you have subverted the entire concept of time and space of mankind since ancient times."

Whether it is that time is not absolute, or that the speed of light is insurmountable, whether it is Reiner's theory of relativity, or this weird but harmonious Igre space, these are all contrary to people's past experience, intuition and common sense, but they are Something with a mathematical basis.

After this meeting, the high-level mages present here have truly realized the importance of mathematics in magic learning. As people's research fields become more and more in-depth, magic will no longer be limited to what people can see and touch. The things we see, whether they are macroscopic changes in nebulae or microscopic atom gathering and dispersion, are extremely difficult to directly observe with ordinary means, not to mention some extreme situations that cannot be achieved even in the future with current means. It is impossible to conduct experiments, and abstract thinking and mathematical logic will gradually become the mainstream of mages' research.

Perhaps this is what Reiner said before. Mathematicians are responsible for discovering formulas, while mages are responsible for finding their meaning.

“Now it seems that Alberton’s three laws of motion are more like low-speed, macroscopic approximations of the motion described in the theory of relativity, at least in the movement of stars and most of the things we can come into contact with. The three laws still apply."

Your Excellency Alberton let out a long sigh, with mixed emotions. He didn't know whether it was because his lifelong efforts were proved to be false, or because he was lamenting that the current magic system based on this did not need to experience a devastating earthquake.

But when these words came out of his mouth, it was indeed quite desolate and helpless.

Ludwig Stein remained silent, but there was already a huge storm in his heart.

Among the two dark clouds hanging over the magical world, the problem of black body radiation finally led people to re-understand light from a microscopic perspective, while the problem of ether drift led mages to redefine time and space from a macroscopic perspective. Questions from seemingly completely different fields actually ended up pointing to the same thing.

Coupled with the proposal of the atomic nuclear structure model, the huge movement of stars is connected with the movement of small atoms, which makes people endlessly daydream.

"We are in the worst era. The knowledge of the past thousands of years is falling apart. Experience and common sense are broken. If you are not careful, you will be left far behind by the rapid development of magic."

The stars and moon on the robe were shining brightly, Her Excellency Rumia Calvados said softly.

“But we are also in the best of times, where microscopic secrets can be glimpsed, macroscopic truths can be traced, and thousands of years of accumulation guide us towards the end of exploration. ~IndoMTL.com~ Her words are also true The voices of many people here are that the mages are extremely uneasy, because any discovery may overturn the past knowledge and destroy the academic tower that has been built for many years. However, at the same time, the mages are extremely looking forward to it because of the two dark clouds. Dissipated, people have taken a major step before comparing both the micro and macro realms. The mages are closer to the truth they are seeking than ever before, and hope is within easy reach.

"It's just Reiner."

Lord Braggs said, he looked at Reiner, his wise sea-blue eyes reflected the handsome face of the young mage.

“The content of the theory of relativity is too impactful for mid-level mages. This is different from the dispute between the wave theory and the particle theory of light. After all, that war cannot be separated from the categories of waves and particles. The concept of space and time in the theory of relativity , the shrinkage effect and the time dilation effect, if they are known to mid-level mages and some high-level mages without any foreshadowing, it is likely to cause a huge cognitive impact, causing a large-scale cognitive collapse phenomenon, thus triggering a real academic earthquake."

What he said is exactly what Reiner considered. The subversion of the concept of space and time by the theory of relativity is not simply a further step, but a complete break and recombination. It is extremely dangerous for high-level mages.

"So, although the High Council recognizes the correctness of the theory of relativity, my suggestion is that this theory and this paper will only be circulated among high-level mages for the time being and will not be published in any public academic journals until we The theory is gradually improved and open to everyone step by step. What do you think?"

Your Excellency Braggs's opinion is very reasonable and no one has any objection.

Reiner doesn't care about these reputations. He only has one idea in his mind now, and that is to perfect the third equation as soon as possible.

Mass-energy equation.
