Meet the principal

The banquet to welcome Reiner back was held as scheduled, and life at Crescent College returned to its original calm state.

Reiner paid close attention to the progress of the ruins. Every week, he received reports from the Rainbow Tower, recording every detail of the excavation of the ruins. Unfortunately, after they left, there was still little progress in the excavation of the ruins. , perhaps because this relic has been lost in the long river of time for too long, and all valuable things have been wiped out.

Turning his attention back from the ruins report, Reiner saw the latest issue of the academic journal.

The cover of "Truth" is an atom model, and what is different from the previous one is that the nucleus of this atom model is no longer a simple ball, but is composed of two different colors of particles.

Opening "Truth", the first article Reiner saw was a paper on neutrons and protons.

The first author of this paper is Reiner Ingle, and the collaborators include several legendary mages and high-level mages. The most eye-catching one is one of the names.

Auriolus von Hohenheim.

No announcement, no news, Master Hohenheim returned to people's view in the form of a paper.

Although the content of this paper is very shocking to the mages, more people's attention is still focused on the news of Master Hohenheim's return.

Not only the Tower of Rainbow, all major media across the continent are rushing to report on Master Hohenheim. Some who can get first-hand information follow and report on Master Hohenheim's movements after returning to the Tower of Rainbow, while other media Then we can only list Master Hohenheim's achievements one by one and make some special topics that are better than nothing.

Reiner's "Daily Prest" has such a special feature, but compared to the achievements of Master Hohenheim, the focus of this newspaper's special topic is more on Reiner who overturned the theory of the four basic elements. After all, Reiner is half a Priest, so he naturally needs to report more.

Retracting his gaze from the newspaper, Reiner turned over the paper and saw the following articles. The title of one of the papers caught Reiner's attention.

"Some Thoughts on Absolute Space-Time and Aether", author: Isharis Alberton.

"Absolute time and space?"

Reiner quickly began to read this paper written by the legendary mage. The starting point of the paper was the inconsistent phenomenon of time flow experienced by the mages in the ruins of Eliot's demiplane. Lord Alberton tried to find the cause of this phenomenon. The reason is that since he is good at the law system and has done a lot of research on force and space, he discussed a concept, that is, absolute space and time.

The concept of absolute time and space mentioned by Mr. Alberton is actually inherited from the recognized principle of the ancient Magic Empire, that is, the laws remain unchanged under any circumstances.

This is easy to understand. The truth that mages are committed to exploring is a formula that can explain any phenomenon. This formula can naturally adapt to all situations. And if a magic law changes as the environment changes, then this The rules are not universal.

Based on this principle, two arguments can be derived, the absoluteness of space and the absoluteness of time. This is also easy to understand. Since the law is unchanged and applicable in various situations, then the space and time described by the law It must also be unchanged. One meter is one meter no matter what the situation is, and one second is one second no matter what the situation is.

It is precisely for this reason that formulas such as Alberton's second law and F=ma can ignore various complex situations and achieve the most essential laws.

This is the principle of relativity between absolute space-time and laws. Described in relatively formal language, it means that the mathematical form of laws will not change in any reference system.

Regarding the issue of ether drift, Lord Alberton put forward a hypothesis, which was first based on the inference that the speed of light is limited.

The inference that the speed of light is limited was discovered by astrology mages when observing changes in the stars. It is known that the orbit of the planet is an ellipse. As the distance between the planet and the sun changes, the cycles of certain star changes will change. According to Regan According to Sri Lanka's three laws, the rotation time of the planet is fixed, which means that it takes time for the star changes observed by the mages to be transmitted to the planet. The farther the planet is from the observation object, the longer the light propagation time, and vice versa. Short, which goes against the past belief that the propagation of light is instantaneous. The Newington-Holland equations were proposed to calculate the speed of light, which also verified this inference.

Sir Alberton assumes that there are two moving observers A and B in the ether. They are separated by a certain distance and synchronize their watches through optical signals. Since they both think they are stationary, synchronizing the clocks only requires Just calculate the time it takes for the signal to be transmitted.

But if there is a third observer C, who is stationary relative to the ether, then in his observation, the two moving observers A and B do not actually synchronize their own watches, but only receive their own watches. The time of the location.

At the same time, due to the definition of ether, people cannot feel the flow of ether, so they do not know whether they are moving. Then all behaviors that use light to calibrate time will have errors.

According to the principle of relativity of laws, this should not happen, because it means that the laws change during motion.

Or mages can choose to abandon the aether doctrine, but even so, similar problems will still arise under certain circumstances. Starting from the aether drift experiment, the foundation of the entire magic is shaking in the wind and rain.

If the discovery of protons and neutrons in atomic nuclei gave mages hope of penetrating into the microscopic world, then the drift of ether and the problems it derived gave mages a sense of despair.

Because for mages, formulas and theorems are like tools for understanding the world, and they are precious crystallizations gained from exploring the world. If the principle of relativity of laws did not exist, then the towers built by mages for thousands of years would instantly disappear. Collapse, because all known laws are not fixed and can be changed. The world will change from knowable to unknowable, which means that the mages' exploration will ultimately yield nothing.

This is no less than the memory from the last era that drove Master Hohenheim crazy. If it weren't for the fact that Lord Alberton's paper did not delve too deeply into the loopholes of the principle of law relativity, plus this basic theory There are not many people doing research, so it is very likely to lead to large-scale academic panic. ...
