From the past to the present, the Dome has changed so much that I am afraid no one can believe it.

From men to little girls, from mediocre to talented, Dome had no idea what was really going on with her. Although she has made up her mind to cherish the present, she no longer hesitates about which is the real self. But the confusion of the two of them still comes to mind from time to time.

In fact, on the body of the dome, there is hardly a trace of a man. Not only has she gotten rid of some of the habits that she has left behind in her past consciousness that she is inclined to men, but she has even completely adapted to a feminine lifestyle, which must have been influenced by her body.

Although this body is peculiar (it suffers from two rare genetic anomalies of mirror syndrome and heterochromia iridosis at the same time), the real puzzling thing is not here, but the weirdness of consciousness inheritance.

It's not easy to describe this weirdness, so let's borrow a story to illustrate it.

It is said that at the famous University of Cambridge in England, such an incident once happened. It was a summer afternoon, and a group of Cambridge professors and their wives sat around an outdoor round table for afternoon tea. At this time, one of the women said that adding milk to tea and adding tea to milk actually results in different tastes of tea. Someone agreed, someone objected, and the story came to fruition.

The confusion of the dome is even more on it. At least theoretically, the lady was undoubtedly right (whether the human tongue can taste the difference is another question). And the confusion of Qiong Nai is that her problem is "pour the same tea into different cups, and the taste of the tea will be different", which is almost an unbelievable bizarre.

The question is very obvious here, why? No one said it clearly at all, including herself.

This kind of weirdness is not simply physical, but closer to a philosophical concept. In fact, when extended to this level, the topic often becomes meaningless and hollow.

To put it simply, it's like a dream. Sometimes I feel like I'm in a dream, and sometimes I feel like I'm in a dream.

Even if I no longer struggle with whether the present is real or not, and decide to live a good life in the present, there is no denying that this indescribable feeling still exists.

If you say that you have been affected by your body and have changed, there are some things that the two have in common. For example, attitudes towards physics.

Why did you study physics?

Whether it is the consciousness of the past or the consciousness of the present, this simple question is not so easy to answer.

In Dome Nai's past consciousness, physics didn't bring her any good memories. It is said that a truly good physicist understands the beauty of physics, but as a student of physics, Qiongno has found a similar feeling in those memories that belong to the past.

Dry, boring, hard, difficult, almost all similar words are filled with memories that belong to the past, and make people miserable to think about it.

But why did he never think of giving up physics as his father now, knowing that it was impossible to develop in this area?

She doesn't understand her past thoughts too much, but she also doesn't understand her current thoughts either.

Because, even now, I don't understand why I still have anything to do with physics, which doesn't bring any pleasant memories.

In fact, after discovering that he had his current identity, Dome had no leisure to think about this at all. But when a chance encounter with physics arose, she jumped into it again with a completely irrepressible inertia.

If there is a reason, physics is probably the only thing that can connect her past and present. Even if you can't let go of the only thing that has been preserved in the past in this memory, there is nothing strange about it.

But when she started to get into physics again, she was shocked to find that it was not the situation she remembered at all.

What I couldn't figure out before, I can now sort it out almost just by going through it in my head. And what you couldn't learn before, you can understand it almost only by reading it once.

The current dome can be said to have truly experienced the beauty of physics. Even if you just understand the equations, you can feel that the laws are so beautiful that people are deeply attracted to them. The pleasure of thinking is so tempting, and sometimes it even begins to wonder why the memory of the past self is so painful.

Actually, she didn't really know why. Because physics itself is wonderful, but my previous self couldn't learn it anyway, and if I couldn't understand it, I naturally couldn't understand it.

However, why did the past self never give up?

Dome sensed that his current father was even more talented in physics than he had been in the past. If even the current father has to give up in the end, why does the past self persist in the end?

In my own memories of the past, there is no answer to this question. And now even if I want to try to answer, it is impossible at all.

The reason is actually very simple, because physics is no longer a painful thing for oneself, and naturally there is no way to explain why physics is still painful for oneself.

The great Wolfgang Pauli may have been able to understand this as well. At least, when he later discovered the famous principle of incompatibility, it was equally inexplicable that he was still shouting that "there is something wrong with physics!" I'd rather I've never heard of physics myself!" , why not change careers to become a comedian as he himself said.

Of course, the situation of the Dome is far from being as simple as Pauli. For Dome Nai, the divide between the past and the present is too strange and obvious to be connected.

Again, the only thing that can connect the past and present of the dome is physics. Not only because physics is something that neither the past consciousness nor the present consciousness can let go, but also because both the past consciousness and the present consciousness are based on the same solid laws and the same rigorous equations for understanding the world in which they live. This can somewhat reassure the Dome who has had such an amazing experience.

However, the things it brings are also a little unreassuring. Especially, after passing the Landau barrier.

This was something that the Dome had never anticipated. Her learning pace seems to most people to be surprisingly fast, but in fact, she has been deliberately limiting herself from moving too fast. On the one hand, it's because she doesn't want too many people to find out about her anomaly; On the other hand, it is also the past experience that has been reminding her not to be rash.

However, after her own teacher came up with such a test without her knowledge (then again, her identity as an admission to Tokiwadai is indeed easy to cause criticism.) And now that all the objections are gone, those who can pass the Landau Theory Essentials exam are of course absolutely eligible to enter the Standing Desk. In that sense, her teacher wasn't completely mindless), and she was shocked to find that she didn't know enough about herself.

Although she had known that she was now quite gifted, she had never thought of her talent as amazing as her teacher. Because her teacher came to the conclusion after comparing her with the same age, she herself knew that this comparison between the same age group was not fair, after all, she had a foundation that belonged to the past.

It wasn't until she had passed the Landau barrier without her knowledge that she realized how unusual she was now.

Roughly speaking, it is similar to the concept of "I thought I would be able to occupy a place in the mainstream physics community in the future, but I didn't expect to be a physicist like Hideki Yukawa."

Your future should have been largely decided, right? If the people who passed Landau's base did not choose physics research as their goal, I am afraid that everyone would feel that it was a tyrannical thing.

Although it is in such an unbelievable way, it seems that the ideal of the past has finally come to be realized one day?

What kind of plot is this? If this is the story of a novel, it's really messy enough.

Lying in the blue sky, the dome felt the intoxicating softness of the wind. LV.4's gravitational domination turns the entire sky into a large soft bed, and there is even an urge to want to fall asleep in it.

Maybe it's a little embarrassing, it's obvious that people with so many experiences are still so obsessed with the childlike dream of being in the sky.

However, those who have really experienced it will probably understand something. In the sky, even the mundane scenery can become grand and magnificent. No matter how magnificent the scenery on the ground can be compared, they can only be a corner of the picture scroll seen in the sky at best.

It's a completely different feeling than sitting in an airplane cabin.

That's probably why skydiving is such a dangerous sport, but so many enthusiasts still enjoy it.

Just as his name reveals (the name of the dome "そらの" literally means "of the sky", and there is also the way to write "empty"), the feeling of being captured by the sky is really impossible to refuse.

The superpower explained by quantum mechanics and the revelation of the nature of gravity brought by general relativity, these two fundamental theories of physics give us gifts to ourselves in the present, which are impossible for me to imagine in the past. At this time, she is sincerely glad that her past self did not give up physics.

There are still many things that cannot be explained, but ...... It's not bad unexpectedly.

No, it's not just not bad, it can already be said to be perfect.

The only regret, or the one who can't let go, is only one point.

For some reason, she lost contact with her best friend back then.

First, the branches are stumbling first, and then the spring is on the clothes. There is no reason and there is no reason whatsoever. It's just that all of a sudden, the news of the two has been cut off.

In fact, the current Dome has been trying to change himself, hoping that he is not completely out of place with the world as he was in the memories of the past. While it's true that some things can't be changed, at least hopefully they can be like Chandrasekhar, the "gray loner". In practice, it seems to have been successful. At least everyone who has come into contact with Dome has a pretty good opinion of her, and she has a very good relationship with everyone she has come into contact with.

However, the number of people she really regarded as her best friend has never increased, not a single one.

Where are the current stumbling and dressing, what kind of life are they living, and what are they experiencing?

This is the only thing that I can't let go of anyway......

The weight of the word "best friend" has not been truly appreciated until now.

I have never experienced such a feeling, neither in the past nor in the present......

==============================================

Uploader's Note:

Saramanian Chandrasekhar: Readers interested in black holes will have heard of the name. He was the discoverer of the ultimate mass of white dwarfs, and his research in this area led directly to the discovery of the black hole theory. But I don't want to talk about his achievements here, I mainly want to talk about him as a person.

Chandrasekhar's is arguably a lone scholar all his life. His discovery was first opposed by Eddington, whom he admired, and then by Albert Einstein, the god of physics in the 20th century. The first half of his life was tragic, and in his own words, "everyone saw me as Don Quixote who wanted to murder Eddington". Perhaps it was this experience that made him accustomed to walking alone on the path of science. Most of the time, he was a true loner. Although he is said to have a good personality and people who have met him have a good opinion of him, it is rare to hear of any close friends of him. After he gained high prestige, he still lived the same life in the same gray suit. So much so that his students called the color "Chandrasekhar Gray", and the name "Gray Lone Wanderer" did not go away.

A person like Chandrasekhar, though mild-mannered, would not fit in with it in that kind of scientific organization. However, I always have a lot of respect for it.

Here, just one story told by Richard Feynman pays tribute to Chandrasekhar -

"One of the most important discoveries in my memory is the reason why stars shine. One of the people who discovered the secret was chatting with his girlfriend under the stars when he suddenly realized that nuclear energy must be the energy source that makes the stars glow. Then his girlfriend said to him, 'Look, how beautiful those twinkling stars are.' He replied: 'Yes.' At this moment, I am the only one who knows why the stars twinkle. But his girlfriend just laughed at him, she had no feelings for dating the only person who knew the secret of the stars glowing. Loneliness is sad, but the world is like that. ”
