Scholar’s Starry Sea

"Teacher Cai said, is it your first time to participate in a Physics competition?"

After learning about Wu Bin a little bit, Bi Wanqing laughed The core issue of today is out.

"Yes." Wu Bin nodded.

"I believe that Teacher Cai has already told you about everything you should know, so I won’t say more about it. Today, I will tell you something more interesting in the Physics competition. You Come with me."

After Bi Wanqing said, he took Wu Bin to an empty classroom, signaled Wu Bin to find a place to sit casually, then picked up the chalk and wrote three on the blackboard. Character.

【mix-up 】

After writing, the patted hand starts to speak.

"In high school Physics, how to take the test, you can hardly jump out of strength and electricity. It is easy to lock the range during study or review, so it is not very laborious."

Wu Bin couldn't help but vomit, "I'm afraid the Physics scum will vomit blood when they hear this sentence. '

"But the Physics competition is completely different. It contains a lot of things. Some people can specialize in one, but if the research direction changes, the brain will start to be confused. The Physics competition is Those who can't mess up can play the game."

Bi Wanqing turned around and started writing on the blackboard.

"The research scope of modern Physics is too large, and there are fewer and fewer intercommunication points. For example, those who do condensed matter do not understand plasma, those who do plasma do not understand black holes, and those who do black holes cannot Those who repair radios can't build houses, and those who build houses can't put satellites, but they all learn Physics."

Speaking of this, Bi Wanqing knocked on the blackboard with chalk.

"And the competition is to ask you to know everything."

"The purpose is to make us a black hole research expert who can repair radios?" Wu Bin couldn't bear to hear this. Take a look at it.

Bi Wanqing smiled after listening to haha, "In fact, it's almost the same. You don't need to be proficient, but you must have an understanding."

After laughing, Bi Wanqing asked Wu Bin:" Tell me about it, why do you want to participate in the Physics competition?"

"Because it is interesting."

"Hahaha, is it interesting? It is indeed a very interesting answer."

Bi Wanqing walked off the podium with a smile and looked at Wu Bin, "Many people think that the biggest help for them in the competition is to go to school and send them. In fact, it is not. I think the greatest significance of the Physics competition for you students is Let you have a framework and systematic insights over the entire contemporary Physics, including engineering and so on.

Bi Wanqing walked back to the podium and continued to pick up the chalk while writing.

"If you can perform well, enter the semi-finals, or even the national competitions, then you will be able to see what Physics' research is like, what is the paper like, by the way, how is your English score? "

"Also...it's okay. "

Faced with Bi Wanqing’s sudden question, Wu Bin brace oneself replied.

"There is a document collection website called arXiv. It is very interesting that many foreign Mathematics experts, Physics scientists and scientists are used to upload their papers to arXiv first, and then submit them to professional academic journals. "

"Why?" Is this document's website authoritative? "Wu Bin asked.

"This process is more interesting. "

Bi Wanqing said and wrote his name on the blackboard.

【Paul Ginsparg 】

After writing Bi Wanqing knocked on the blackboard, "arXiv is Established by this Physics scientist in 1991, the original intention of the website was to collect preprints of Physics papers, but later, Mathematics, astronomy and other fields were gradually expanded into it. "

"Oh~" Wu Bin is nodded as if he understands but he does not understand.

Bi Wanqing slightly smiled: "Do you know what kind of influence this website has had afterwards?" "

"I don't know. "Wu Bin shook his head decisively.

"The existence of arXiv is one of the factors that created the so-called open access movement in the scientific publishing industry. Nowadays, Mathematics experts and scientists are used to uploading their papers to arXiv before submitting. For professional academic journals, this trend has had an objective impact on the business model of traditional academic journals. "

"It's a bit like...the high-end version of Baidu Baike? "

"You understand that... it's okay, but this is high, probably as high as Yao Ming. "Bi Wanqing said somewhat humorously.

"Later, Paul Ginsparg won the MacArthur Fellowship in 2002 by relying on this website. This is the genius award commonly known in the United States and is regarded as one of the highest awards in cross-fields. The commendations are all creative talents who have played an important role in social development. "

"It looks like very difficult to deal with. "Unclear Wu Bin nodded.

Bi Wanqing nodded, continue to say.

"Now those scientists upload their papers to arXiv, one is to prevent their ideas from being used in the papers. It was plagiarized before being included, uploaded to it to make a pre-recording, and finally proved that it was his original according to the upload timestamp. "

"The second is for the above'recognition' system, the vernacular is peer review, that is, after the paper you submit is strictly reviewed by the manager, then another person with recognized qualifications on the forum will come I'll endorse it for you, but what's interesting is that some of the articles that won the Nobel Physics Prize in Brian Josephson were rejected by the manager because his articles contradicted the orthodox view of string theory. "

"Then this big guy won the prize later as a slap in the face?" "

"Otherwise, why do I say something interesting?" "

Wu Bin smiled after listening to haha, and found this teacher more interesting.

"In short, what I want to tell you is that arXiv is a very interesting website. It learns a lot of knowledge that is not accessible in schools. For example, Grigori Perelman's proof of Poincaré Conjecture has been kept in the form of a preprint. "

"Oh oh..."Although Wu Bin is not very familiar with these big guys, he has already ignited a huge curiosity about this website.

"So again Turn back to the question I started asking you, how is your English? "

Listening to Bi Wanqing asking himself again, Wu Bin knew that this teacher must have seen his results in other subjects, so he touched his nose and said: "Not so good..."

p>

"hahaha, I am not asking you to embarrass you, but to make you understand that English is of great use for you to learn any science, so it is not too bad. "

"English also helps Physics? "

It’s really ignorance that limits his imagination. He can understand Mathematics and it’s very helpful to Physics, but English can also be involved?

Bi Wanqing laughed and turned around Three words are written on the blackboard.

[Knowledge Base]

"Because the knowledge base of the world is mainly in English, such as teaching materials, such as online knowledge base, and Baidu Baike you just mentioned is a knowledge base shared with foreign Wikipedia, these all are world. "

"Russia..." Wu Bin scratched his head, still a little confused.

"Don't understand, listen to me give you an example. "Bi Wanqing said and picked up the chalk.
