"Listen to Mr. Cai, is it your first time participating in a physics competition?"

After getting to know Wu Bin a little, Bi Wanqing smiled and threw out today's core question.

"Yes." Wu Bin nodded.

"I believe Mr. Cai has told you what you should know, I won't say more, I'm going to tell you something more interesting in the physics competition today, you come with me."

After speaking, Wan Qing took Wu Bin to a classroom where no one was, motioned for Wu Bin to find a random seat to sit, and then picked up the chalk and wrote three words on the blackboard.

【Hodgepodge】

After writing, he clapped his hands and began to speak.

"As for high school physics, no matter how you take the test, you basically can't jump out of force and electricity, and the range is easy to lock in when you study or review, so it's not very strenuous."

Hearing this, Wu Bin couldn't help but complain in his heart, "This sentence was heard by those physical scumbags, and I was afraid that I would vomit blood." ’

"But the physics competition is completely different, it contains a lot of things, some people can specialize in one thing, but if the research direction becomes more, the brain will start to mess up, and the physics competition is a game that can only be played by those who can't mess around."

After Bi Wanqing finished speaking, he turned around and wrote on the blackboard and said.

"The research scope of modern physics is too large, and there are fewer and fewer points of communication between them, for example, those who engage in condensed matter do not understand plasma, those who engage in plasma do not understand black holes, those who engage in black holes do not know how to repair radios, those who repair radios cannot build houses, and those who build houses do not put satellites, but they all learn physics."

Speaking of this, Bi Wanqing tapped the blackboard with chalk.

"And the competition is to ask you to know a little bit of everything."

"So we're going to be black hole experts who can fix radios?" Wu Bin couldn't help but feel a little skinny when he heard this.

Bi Wanqing laughed after hearing this, "Actually, it's almost like that, you can not be proficient, but you must have understanding." ”

After laughing, Wan Qing asked Wu Bin: "Tell me, why do you want to participate in the physics competition?" ”

"Because it's so interesting."

"Hahaha, is it interesting, but 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 on to higher education and escort, but in fact, I think the biggest significance of the physics competition for you students is to let you have a framework and a systematic view of the entire contemporary physics, including engineering and so on."

After Bi Wanqing finished speaking, he walked back to the podium and continued to pick up the chalk and write and speak.

"If you can perform well and enter the semi-finals, or even the national competition, then you will be able to see what the scientific research of physics is like, what the thesis is like, by the way, how is your English score?"

"Also...... It's okay. ”

Faced with Bi Wanqing's sudden question, Wu Bin replied stiffly.

"There's a website called arXiv, you can go and browse around, and it's a very interesting place, there are many foreign mathematicians, physicists and scientists who are used to uploading their papers to arXiv and then submitting them to professional academic journals."

"Why? Is this documentation site authoritative? Wu Bin asked.

"It's more fun."

Bi Wanqing said and wrote his name on the blackboard.

Paul Kingsbarger

After writing, Wan Qing tapped on the blackboard, "arXiv was established by this physicist in 1991, and the original intention of the website was to collect preprints of physics papers, but later, mathematics, astronomy and other fields were slowly expanded. ”

"Oh~" Wu Bin nodded as if he didn't understand.

Bi Wanqing smiled slightly: "Do you know what kind of impact this website has caused later? ”

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

"The existence of arXiv is one of the factors that have created the so-called open access movement in the scientific publishing industry, and mathematicians and scientists are now accustomed to uploading their papers to arXiv before submitting them to professional academic journals, which has caused an objective impact on the business model of traditional academic journals."

"It's kind of like ...... High-end version of Baidu Encyclopedia? ”

"You understand it that way...... It's okay, but this one is high, probably as high as Yao Ming. Bi Wanqing said with some humor.

"Paul Ginsbag's 2002 MacArthur Award, commonly known as the Genius Awards, is regarded as one of the highest awards in the field of science, recognizing creative talents who play an important role in the development of society."

"It looks like it's amazing." Wu Bin, who was unconscious, nodded.

Bi Wanqing nodded and continued.

"Now those scientists upload their papers to arXiv, one is to prevent their ideas from being plagiarized before the papers are accepted, upload them for pre-inclusion, and finally prove that it is 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 has passed the strict review of the administrator, and then let another person with accreditation qualifications on the forum to endorse you, but the interesting thing is that some of the articles of Brian Josephson, who won the Nobel Prize in Physics, were rejected by the administrators because his articles contradicted the orthodox view of string theory."

"Then is this big guy a slap in the face when he won the award later?"

"Why else would I say something interesting?"

Wu Bin laughed after hearing this, and felt more and more that this teacher was very interesting.

"Anyway, I'm going to tell you that arXiv is a very interesting website, and you can learn a lot of things that you can't get in school, such as Grigory Perelman's proof of the Poincaré conjecture 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 going back to the question I started asking you, are you good at English?"

Hearing Bi Wanqing ask himself again, Wu Bin understood that the teacher must have seen his grades in other subjects, so he had to touch his nose and say, "It's not very good......

"Hahaha, I'm not asking you this to embarrass you, but to make you understand that English has a huge effect on your learning of any science, so you can't do it."

"English also helps with physics?"

This is really ignorance that limits his imagination, mathematics he can understand is very helpful for physics, but English can also be relate?

Bi Wanqing smiled, turned around and wrote three words on the blackboard.

【Knowledge Base】

"Because the world's knowledge base is mainly in English, such as textbooks, such as the Internet knowledge base, as well as the Baidu Encyclopedia you just mentioned, and foreign Wikipedia, these are all knowledge bases shared by the world."

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

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