Tower of the Rainbow.

The coldness of late autumn makes the mages who are in a hurry also change into thicker jackets. This new style of jacket combines traditional mage robe and simple dress suit design, which is the favorite of young mages.

The fourth ring mage Ora Diomudo shrank his neck, and the temperature of the Rainbow Tower was lowered, making the mage who was afraid of the cold and cold very uncomfortable.

He walked on a path with few pedestrians and turned around and walked into an inconspicuous building.

"This damn weather is so cold."

When Olayi walked into the hall, she saw Wendy, a girl at the front desk knitting a scarf. Her hands were moving the spinning needles dexterously. A scarf with beautiful patterns could be seen for the first time.

"Hello, Mr. Diomudo, it's so early today."

Wendy showed a bright smile when she saw Euler, which made Euler feel that the air was a little warmer.

The cute young lady came to the institute as the front desk six months ago and soon became friends with most of the young mages. Ora naturally felt good about her. He felt that the interaction between the two had surpassed colleagues in other institutes, and was about to wait until the winter solstice, which was the first day of the moon falling.

Now Wendy has knitted this scarf in her hand for herself!

Euler nodded slightly. He could not show it too clearly, so Eugen accelerated his pace and walked around the corner before climbing the stairs.

When he came to his laboratory, Oula sorted out her clothes that were blown by the autumn wind before she pushed the door open.

"Impossible, this is definitely not right!"

As soon as he walked in, Euler heard a quarrel. He saw two people facing a book and was excited.

"What's wrong, Robinson, has someone published another paper to verify the particle nature of light?"

Euler noticed that the book was the latest issue of "Truth". It was released today and he had not had time to read it.

The person who started yelling was Robinson, who was big and thick. It took ten years to get promoted from the Third Ring Road to the Fourth Ring Road. Although he was old, he was the most immature and showed more emotionality in everything.

Robinson is also a staunch supporter of the few light fluctuations in the institute, and he disagrees with Euler.

"No, Ola, come and take a look at this paper."

The man with glasses beside Robinson's side, Odyssey handed Ola the latest issue of "Truth".

Euler took over the thick academic journal and saw that the cover image was a tiny particle surrounded by countless shining spots of light.

This Euler has heard of, and the famous Reiner Ian Grey designed another experiment to study the internal structure of the particles and obtained an atomic model like this picture.

What a genius!

Euler admires Reiner Ian Gray very much. The rational thinking he showed is quite amazing. Euler has fantasized more than once that if he could be reborn a year ago with memories, and those discoveries were all raised by himself, then how wonderful life would be.

Of course, it's just thinking about it.

"Does this atomic model matter?"

Euler did not open the academic journal directly. He asked in a pretentious manner that he had read this paper because of his personal connection. Euler was about to wait until they asked before answering it fluently, which made him seem knowledgeable.

"No, you turn to the last article."

Odyssey skipped the previous papers directly and turned to the end.

Generally speaking, the importance of a paper in an academic journal is arranged from the front to the back. The first article is usually the most valuable and important paper in the current issue.

The last article is relatively less important and may even have a much controversial paper.

Ola was stunned for a moment, swallowed the pretentious words he was about to blurt out, and honestly turned to the position of the last paper.

"Verified Experiment on Ether Drift and Its Results Analysis".

“Ether drifting?”

Ola frowned and hurriedly continued reading.

Ether is a medium filled in space proposed by the mages of ancient magic empires to explain the role of magic transmission. In the theory of ether, light relies on ether, and the world is full of ether. The long-distance transmission of magic also relies on ether as a medium.

Of course, this theory has many flaws. In modern times, many theories have been proposed to refute the Ether theory, but none of them hurt the root cause.

The most famous of them is the ether drifting theory.

Because according to the ether theory, ether should be stationary with respect to the sun and move relative to the planet, then, according to the law of planet movement, ether should have a speed of 30 kilometers per second relative to the planet, which is also called the "ether wind".

This paper is an experimental record that verifies the existence of ether drifting.

The authors of the paper are Prous Straynold, the 6th Ring Road mage, and Newark Hartford, the fifth Ring Road mage, who geniusly thought that if the etheric wind really existed, then the propagation time of light should change along the direction of the planet's rotation and perpendicular to the planet's rotation.

So, they designed an experiment and set up mirrors in two directions parallel to the ground and perpendicular to the ground to accurately measure the propagation time of light, but they found that there was no difference in the time when light traveled back and forth in these two directions!

If this experimental conclusion is true, it means that there is no ether wind between the planets, and the theory of ether will also be fundamentally shaken.

However, the system of light derived from the existence of ether is an electromagnetic wave. If the tower of the ether theory collapses, then the fluctuation theory of light will be affected unprecedentedly!

This is also why Robinson, who insists on the fluctuation theory, is so excited.

"There must be a problem, let's do the experiment now!"

Robinson was blushing and was about to run out of the door, but he bumped into someone walking in from outside.

"What's wrong, so hurry?"

The other party did not question Robinson, but asked.

"Teacher, in the new issue of "Truth", someone proposed that an experiment denies the Ether theory, and I am preparing to repeatedly verify this experiment."

Robinson saw clearly the appearance of the opposite side before calming down and answering a little.

The mage opposite is handsome and handsome, wearing one-sided glasses, neat hair, and a trendy dress and robe. This mage is a famous playboy and has an indescribable ambiguous relationship with many women. But at the same time, he is also a high-level mage who set up his own research institute at a young age.

Ludwig Stein smiled slightly when he heard his student's words.

"We will put the experiments on ether first, and here is a more important study."

His Excellency Stein handed the research materials in his hand to the students.

On the first page of the research data, there is a simple word written.
