(Sunday, October 21, 2012; stairwell)

By the time Sora Akiyama and Yuta Tomigashi returned to their apartment, it was already completely dark. The orange lights of the pen %fun %pavilion www.biquge.info add a bit of warmth to the cold corridor.

Yuta Tomigashi lives on the second floor, so he is the first to say goodbye, and then the bird Yujuka and Chixia arrive at the doorstep. Unexpectedly, as Sora Akiyama was about to step up the steps leading to the fourth floor, Toka Totori covered the door and stopped him.

"Miss Shihua, what's the matter?"

"Akiyama...... Professor, you're really low-key. The other party looked at him with a strange look, "A seventeen-year-old professor, a genius scholar who straddles the three major fields of mathematics, computer science, and neuroscience, can ......."

She didn't finish her sentence, just looked at him quietly.

"Well, that's what you're talking about. I didn't expect to be discovered. Sora Akiyama wasn't surprised. Although he has a very low-key life, it is not surprising that as long as he conducts academic research and publishes results, his name will appear in journals and be searched by search engines.

Hey, hey, this is not something I can control, if I make up the script and then transmit it, then I will play with a yarn! Damn! I knew that I would not transmit the strange things such as "The Thirty-six Volumes of the Daomen Number Theory" and "The Seven Chapters of the Taiqing Field Theory".

Alas, it's all too hilarious to play in the last world.

"To be bold, you really don't look like you're that age. ”

"It's just a little disguise. Sora Akiyama took off his glasses, which had no real effect, and then scratched his hair, "Like this, it is inevitable that some tedious things will arise when teaching. ”

The little bird Yu Shihua was silent for a moment and said, "I don't want Liuhua's ......"

"Miss Shihua, I think you misunderstood. Sora Akiyama interrupted, "Human beings are not purely rational creatures, and civilization is definitely not just born of reason, so why force her?"

"But ......"

"In today's world, the development of science and technology is getting faster and faster, and it will be followed by profound changes in the whole society. When material needs are satisfied, people's pursuits will naturally turn to the spiritual realm, and how can Rokuka's talent be said to be wasted? When virtual reality and augmented reality become popular, is her 'delusional' still nonsense?" said Sora Akiyama and paused deliberately, "You are a senior chef, I don't know if you have paid attention to the research progress of taste. Taking saltiness as an example, the reason why table salt has a salty taste is because sodium ions are transported into taste cells by sodium ion channels, and then the cell membrane potential changes to produce a series of nerve signaling. My main focus is on brain-computer interfaces. I can responsibly say that in ten years' time, virtual gastronomy will no longer be a dream, but only a small and inconspicuous development. ”

In the past few months, Akiyama has invaded the network of the [Galaxy Federation] several times. Limited by the human body, he could only glimpse the tip of the iceberg, but it was enough. The strong artificial intelligence life of the [Wise Man] is not a single race, but a group with a large number of branches. Among them, there are not only logical thinkers who are close to pure rationality, but also artists who are free to let their minds fly; some [wise men] control hundreds of millions of weak artificial intelligence, responsible for coordinating the construction of civilized star fields, and some [wise men] are born from the spark of the hearts of tens of millions of mortals, and sensibility and reason are fused. In a sense, the collection of the [Galactic Federation] as a whole is an incomparably large, impersonal being.

As an outsider, Sora Akiyama was confident that the "Other Shore" plan would go smoothly.

"Of course, I will use a guided way to make Liuhua turn her attention to learning. It was almost time to pretend to be forced, and he told the other party publicly.

“…… Hawkers, although I don't know why I feel very uncomfortable," Little Bird Yu Shihua pouted, "but I really thank you." ”

She bowed slightly and said, "Please." ”

"Huh, do us magic training?" Yuta Tomigashi's eyes widened.

"Yes, to be precise," Akiyama paused, "at the request of the Holy Counselors, you were given special training. ”

"[Reincarnation Master], I didn't expect that even you would be ...... by the [Holy Temperer]" Xiao Bird You Liuhua's expression was grim, and his face was unkind, "Sure enough, the power of the Magic Administration is everywhere?"

"Hmph! The Magic Administration doesn't deserve to carry shoes for this seat. [Evil King's True Eye], although this seat admires your combat prowess, but now it seems that you are still too naive![Holy Temperer] If he wants to deal with you, why should he cook for you every day?"

"Hmm...... What's this...... This is because...... "Little Bird You Liuhua seems to be a little lacking in confidence," in the end, this is just a battle of ideas! Yes, that's it!"

"Hey, you!" Tomigashi on the side couldn't help but laugh.

"And then on to the matter of special training, this special training is aimed at the problem of your weak foundation in magic theory. Sora Akiyama ignored Yuta Tomigashi's continuous glances, "A true great magician should never be satisfied with being a rude battle maniac. ”

"The [Evil King's True Eye] is the strongest, I don't know if Your Excellency has any advice?" said the little bird You Liuhua proudly.

"The power of the True Eye of the Evil King is indeed very powerful, but what do you have besides it? Do you know how the life magic modifies the ingredients of herbs? Do you know how the trajectory of the arcane missile is calculated? Do you know the algorithm behind the magic machine? That's why the Holy Therapist commissioned me to train you. ”

"Well, okay. ”

"Unfortunately, I don't have enough time to teach you personally, so it's up to you to do so. The essence of science and magic is the same, both are systems for constructing ordered knowledge based on testable explanations and predictions about the form, organization, etc. of objective things. Therefore, to learn magic well, you must also learn science well. ”

Sora Akiyama unceremoniously brought out the knowledge of the previous world. Considering the difference in the laws of the world, he hesitated for a while, and finally decided to stop at the point.

"So what books does Mr. Akiyama recommend?" Yuta Tomigashi gave him an admiring look.

"Ahem, what's this...... First of all, the content in the textbook must be learned well as the foundation, and then it can be expanded to a deeper level. For example, physical ...... Ahem, it can also be called the basis of the arcane system, you can start with the "Feynman Lectures on Physics", and then consider the "Landau Ten Volumes" and the like......"

Isn't it too much for me to fool me like this? Forget it, anyway, I don't expect them to really watch it, even if they do, there is no loss, it is estimated that the [Galaxy Federation] will also support it remotely, and I don't have to worry about not being able to understand it.

After sending off Yuta Tomigashi and the others, Sora Akiyama looked at the empty living room, then turned his head to look at the kitchen, and suddenly remembered that there seemed to be no ingredients in the refrigerator, and he hadn't bought food today.

"Damn, my dignified [observer] has actually fallen to this point sometimes! No, no, no, let's order a takeout first. ”

(Monday, October 29, 2012 night; apartment 4th floor, Akiyama Sora House)

At the end of a busy day, Sora Akiyama lazily reclined on a comfortable recliner, tablet in hand, ready to read the cutting-edge content of the new release.

After the last conversation, Yuta Tomigashi and Yuroka Kotori, two patients with secondary two diseases, can be regarded as untying their hearts, and finally went to the dojo of European swordsmanship to learn according to Sora Akiyama's script. Funny to say, Yurokuka, a bird who has always been fond of heavy weapons, planned to use the heaviest two-handed sword, but because of her lack of strength, she finally turned to the slender Western sword.

According to her, it was because "these unenchanted weapons are quite difficult to use".

Shaking his head, Sora Akiyama refocused his attention on the tablet. Soon, he was caught up in a paper from Harvard's Charles Lieber lab on a new brain-computer interface.

This is a paper published in nature_methods that introduces a novel flexible grid electronics-based platform for chronic in vivo recording and stimulation. This is an injectable, flexible mesh brain electrode that enables long-term, stable monitoring of cellular activity at the level of single neuron cells in the mouse brain, and is expected to be used to study mapping, regulation, and learning, as well as changes associated with aging and neurodegenerative diseases.

Instead of the rigid, dense electrodes previously used, the brain-computer interface designed by the team is an extremely flexible strip-like grid electrode consisting of two thin layers of flexible polymer and a gold wire layer sandwiched in between. They designed a series of experiments in which flexible mesh electrodes were curled into elongated needles and injected into the brain through a perforated skull in mice, while the other part was connected to a computer to control the application of electrical stimulation and monitor neuronal activity.

In the article, the researchers claim that the control and power supply parts will eventually be fully implanted in vivo, which reminds Sora Akiyama of research progress in another field – a new programming language called the "chain language" co-created by Brandon Lucia, an assistant professor of electrical and computer engineering at Carnegie Mellon University, and his PhD student Alexei Colin. The language is designed to provide reliable software support for computers that work intermittently. A "chain" program is a set of tasks defined by a programmer that can compute and exchange data through a "channel". Since its input and output channels are separated, it guarantees progress at the task granularity when the device's energy supply is interrupted and then restored, allowing the task to be restarted without inconsistencies. The researchers implemented "chain" as a C language extension and runtime library, and used "chain" to implement machine learning, encryption, compression, and sensing. This means that the control part implanted in the body in BCI research will not have to worry about errors due to the termination of the energy supply.

"It's still a long way from Akihiko Kayaba's vision, but at this rate of progress, I'm afraid that within ten years, nay, maybe even shorter, we will be able to reach that level...... In other words, will this have anything to do with the [Galaxy Federation]?"

Sora Akiyama recalled the amazing [Spiritual Network]. Unfortunately, the [Mind Network] involves so many esoteric mathematical principles that the human brain simply cannot handle it. But his intuition told him that there must be some connection between the two. It is estimated that nine times out of ten, Kayaba Jinghiko has been secretly affected by the [Galaxy Federation].

"Well, let's see if there's anything else...... Eh, Xu Mingshan's email?"

During this time, Akiyama Kong and Du Mu have also contacted each other through QQ, and it is a little unusual to send an email, but it may also be that the other party does not want to disturb his work.

"Lab internship?"

Xu Mingshan said in the email that he wanted to use the vacation time to apply for an internship in the laboratory to enrich his resume, and also planned to learn about the points of interest in the field of scientific research.

Each laboratory usually has a few places for summer research every year, and Akiyama's own laboratory has also had undergraduate students come to intern. He thought for a moment and replied:

"It's great to see that you started preparing so early, and with limited space, it's only natural that the sooner you apply, the better. Generally, this type of internship is available during the summer vacation, but you certainly can't wait until the summer vacation to start applying. ”

"In terms of application letters, the first thing is to express your interest in the professor's research direction, then to self-finance, after all, you are not a graduate student or a doctor, and you don't need to think about the salary for summer internships; secondly, personal education and professional interests, as well as self-introduction, internship time, etc. For internships, relevant knowledge reserves are indispensable, and the professor's articles published in the last year should be read more or less, so as not to be confused during the internship. ”

"In terms of information, you can refer to some related rankings, such as usnews, etc., of course, it is better if you have already paid attention to laboratories in related fields. ”

"If you're interested in cognitive science, neurobiology, or computer engineering, you can also consider interning with me. However, I don't know how to release water, so if you want to come, you should stock up on the corresponding knowledge. ”

Pressing "send", Sora Akiyama got up from the recliner, moved his muscles, and prepared to go to bed.

"I don't know who is a little higher in force than Du Mu and Yuta Tomigashi and Little Bird You Liuhua?"
