Chapter 449

After dinner, Lena went back to his room, sat down at his desk and finished reading the journals he had not finished during the day.

He saw that after the paper on the principle of relativity of law was put forward by Mr. Alberton, a silent debate arose quietly.

In this issue of truth, Newington and Holland published a revision of the Newington Holland equations based on the non etheric environment, which is another revision of the Newington Holland equations that was questioned because of the etheric drift experiment.

In his paper, Mr. Newington mentioned a very important problem, that is, according to the description and calculation of the equations, they got the value of light speed is close to 300000 km / s, and this value will not change due to the change of observation means or reference frame.

When he saw this, there was a sound of footwork behind him, which made him turn around.

Claire's hair is still wet. She is wearing a blue Pajama with a bear pattern. She is wearing flannel slippers and holding a book in her hand. Even though she is wearing loose pajamas, Claire's figure is still indistinct.

"Why didn't you blow dry your hair? It's easy to catch a cold."

When Lena saw Claire with loose hair, he put down his journal and stood up.

He sat Claire on the bed, raised his hand, and a warm, strong wind blew from his fingers to Claire's long hair.

The long golden hair is slightly curled and lifted by the hot wind. Lena's other hand and fingers are open, gently scattered and constantly shaken, so that each hair tip can be quickly dried.

So Claire sat on the bed, hands on his knees, at Lena's disposal.

You can smell a faint fragrance in the air, which is the fragrance of shampoo. Through her blonde hair, Lena can see Claire's white back neck, over her neck, and from her point of view, she can see a little white on her chest.

"It's too much trouble blowing your hair."

Claire said she felt the palm of Lena's hand fiddling with her hair, but she felt very relieved that she wanted it to last longer.

"After that, it's better to develop a magic prop that can air dry automatically. It shouldn't be difficult to achieve."

Said Lena, caressing the tip of Clare's hair and touching her back from time to time.

"By the way, Lena, I heard from fina today. It's like you have a problem with the magic computer?"

Asked Clare, turning her head slightly and looking sideways at Lena.

"Well, there are indeed some problems. In short, the past cognition thought that the propagation of light is instantaneous, but now according to the calculation, the propagation of light has a limit speed, and the signal transmission of magic computer is essentially the transmission of electromagnetic signal like light, which leads to the problems of time calibration and signal accuracy."

Lena explained in a way that would make Claire understand as much as possible, but although Claire's magic level is not high, he will patiently listen to Lena's explanation and try his best to understand.

"So why is the speed of light limited? If you give it energy, won't you be able to increase its speed all the time? "

Clare thought about it and asked.

Her question stunned Lena. I didn't expect that Claire could find the essence of the problem in such a short time. His silence made Claire curious, and he turned to face Lena.

"What's the matter, Lena?"

Claire tilted his head and looked at Lena with wide violet eyes.

"No, your question is good."

Lena smiles and touches Claire's head.

"The problem now is that the Newington Holland equations, the equations describing the mutual transformation of electric field and magnetic field, show that the speed of light has a limit value, which is a constant value in vacuum. No matter what reference frame or angle is used, this value is fixed and cannot be surpassed."

Lena waved his hand and projected two roughly constructed carriages in mid air.

"Let me give you an example, like these two carriages. If they travel at the same speed, although the speed of the two carriages is still their own speed from the ground, the speed of the other carriage from one carriage should be the sum of the two. This is the difference between the reference frame and the basis of our current motion system."

Claire nodded as the two carriages drew closer.

"The reason for this phenomenon is that we think that time exists out of space and is a constant thing. The definition of speed is the distance that the object moves in unit time, and the relative speed is the distance that the object moves relative to the reference frame. At the same time, all the laws of motion are the same for moving or stationary objects, and they are constant in time In this case, the relative velocity is naturally the sum of the velocity of the object itself and that of the reference frame itself. "

Seeing that Clare listened with interest, Lena went on.

"But light is not the same. According to the description of the Newington Holland equations, if two beams of light emit relatively, the speed of the other beam from one beam is not the sum of the speed of the two beams, but it is still the limit value. To be exact, it is close to 300000 km / s. our past law of motion fails in the speed of light.""How is that possible?"

Claire was a little surprised, which completely overturned her common sense. If it wasn't for her and Lena's exposure to many things beyond common sense, Claire might have shaken her cognition.

"This is the contradiction. The Newington Holland equations prove this point mathematically, but they violate our cognition in real life and the laws of motion that have been established for so many years."

Lena spread out his hand, and the two carriages turned into particles and disappeared.

"To solve this problem, there are only two choices. One is to prove that the Newington Holland equations are wrong, the other is to prove that the law of relative motion is wrong. For the mage, these two choices are undoubtedly extremely difficult and painful."

"And what does Lena think?"

Claire raised her hand and touched Lena's cheek.

"I support your excellency Newington's view."

Lena grabs the hand and holds it in the palm. Claire's little hand is soft and warm.

"After all, this is the answer based on mathematics. Many times, what we see often deceives our eyes, but mathematics doesn't."

"Then you have to work hard."

Said Clare, as if tired of Lena.

"Nothing. As long as you're here, it's not hard."

Claire blushed at Lena's words and couldn't help lowering her head, but Lena had already got by.
