Chen Ya said calmly, "It's just a simple friendship."
"friend?"
"Yeah, just a good friend."
Yan Yiting suddenly turned around and looked at Chen Ya:
"There really are beautiful female executives in big companies!"
"Yes." Lu Aiai and Chen Ya answered seriously at the same time.
Yan Yiting is really at a loss.
Chen Ya and Gu Yuqing are not boyfriend and girlfriend in name. Although they are very close and maintain a very ambiguous tacit understanding, they still cannot let go of the fact that they are in a boyfriend-girlfriend relationship.
The main reason is that there is pressure from Gu Yuqing's family, and Gu Yuqing cannot fall in love or get married in her life.
If she was caught, Gu Yuqing's life trajectory would be rewritten.
So no matter where he goes, Chen Ya will insist on being loyal to Gu Yuqing and that he and Gu Yuqing are just friends.
Despite all the reasons, what Lu Aiai heard was completely different from what Chen Ya thought.
After hearing Chen Ya's denial, she felt her body was very light, and her heart seemed to float into the air. An inexplicable and happy emotion filled her body.
As for why Chen Ya kissed Gu Yuqing and they were so close, it was no longer important to her now, or she had selectively forgotten it.
"I came to Professor Yang this time because I had a request for him," Chen Ya said. "I want to make some breakthroughs in room-temperature superconductivity, and I must use the laboratories of mature domestic teams."
Lu Aiai’s mind was full of “borrow, borrow, borrow”, but she still had no expression because she had forgotten how to speak.
"Ah? Aren't you from a gaming company? Why would you want to do this?" Yan Yiting asked curiously, "Aren't you busy with work?"
What she actually wanted to ask was why Chen Ya’s work was so unsatisfactory, and whether he had no more games to make.
Chen Ya said frankly, "Our company's next step must involve major breakthroughs in several technological areas, including room-temperature superconductivity. If we want the company to develop smoothly, we must start planning now."
Yan Yiting has always been immersed in an academic environment and doesn't know much about the transformation of technology into civilian applications. She especially doesn't understand how a game company could be related to room-temperature superconductivity.
"Room-temperature superconductivity, if I remember correctly, simply refers to the realization of superconductivity under room temperature conditions, right? Does this have anything to do with your company's business?"
Chen Ya smiled and said, "Of course it is related. It's better to say that it is related to everyone in the world."
"What do you mean?" Yan Yiting looked at Chen Ya with confusion.
She only knew that room-temperature superconductivity was of great interest to the academic community, and every breakthrough was big news. Some even said it would be the trigger for the Fourth Industrial Revolution.
But she didn't know exactly why this happened.
"Well, to understand room-temperature superconductivity, you first need to know some of the underlying prospects," Chen Ya said. "You know about direct current and alternating current, right?"
Yan Yiting rolled her eyes. "Of course I know this. It's junior high school knowledge, right? Direct current is current that flows from the positive electrode to the negative electrode, and the direction and magnitude of the current do not change. Alternating current is current that changes periodically between the positive and negative electrodes."
Chen Ya nodded. "Yeah, that's a very physics-oriented answer. Then do you know which electrical appliances you use use alternating current and which use direct current?"
"Well……"
When asked this question suddenly, Yan Yiting was a little confused at first, but she quickly counted on her fingers:
"Washing machines, refrigerators, air conditioners, light bulbs... these all use AC power, right? Actually, all home appliances basically use AC power. What about DC power... computers?"
Chen Ya took out his cell phone and waved it in front of her: "And this."
"Oh yeah, and a cell phone."
Chen Ya nodded and said, "Mobile phones and computers, these electrical appliances with precision components inside, need to identify high and low potential differences and cannot use alternating current, so they all use direct current."
After a pause, he continued, "In fact, in the early days of mankind's invention of electricity, there was a long period of competition between direct current and alternating current."
In the early days of electricity use, General Electric Company, headed by Edison, had been promoting direct current.
Compared with alternating current, direct current has a fatal weakness - when transmitted over long distances, the voltage of direct current will drop significantly.
With the technology at the time, the DC voltage was not enough to light a light bulb if the distance was more than one kilometer.
Therefore, General Motors invested heavily in power plants, building an average of one power plant per kilometer in the city.
At that time, Tesla was an electrical engineer under Edison. He pointed out the advantages of alternating current many times, but Edison did not adopt it in the end for commercial reasons.
Later, Tesla suffered a lot of unfair treatment at work (Edison was not a good boss), and finally left in anger and joined Westinghouse to promote the commercialization of alternating current.
In order to fight against alternating current, Edison used many despicable means to demonize alternating current, which initially created a great obstacle to the promotion of alternating current.
But thanks to a World Expo, Westinghouse made a comeback and ultimately helped alternating current achieve great success.
Because of the failure of direct current, the financial situation of Edison's General Electric Company deteriorated sharply, eventually leading to its merger into General Electric.
"To discuss room-temperature superconductivity, we must first understand this case. Only then can we more deeply grasp its significance," Chen Ya said. "We all know that direct current was eliminated due to power loss, and power loss is due to the resistance in the conductor."
