Chapter 675 Attack (2)

In midsummer, Tokyo is hot.

Shen Guanglin took Li Li back to the capital, and it was still cool in the capital.

Professor Shen is finally back!
In fact, scholars in Fusang have long been looking forward to it.

Last time he left in a hurry, many people wanted to exchange ideas with Professor Shen, but they didn't have this opportunity.

Now, Professor Shen Guanglin is back again, you can't miss it anymore.

To be honest, Shen Guanglin felt that the feeling in Fusang was better than that in Citigroup.

Or the rich and scholars here will respect people more.

In Citigroup, in New York, they didn't regard you as a scientist, they regarded you as a business competitor, so some of the methods they used made Shen Guanglin, who was used to being flattered, very unhappy.

In Fusang, no one mentioned this, including Takeda, they were unwilling to invest in the Human Genome Project, and they said it very euphemistically.

Of course, from the perspective of national sentiment, Shen Guanglin actually hates Fusang people, especially since his hometown is still from Jinling.

But sometimes it's hard to really hate them when you see them being extremely polite and feel that they're being polite.

It would be fine if Shen Guanglin faced only those bald middle-aged men, after all, people really don't want to see that wretched face.

However, they actually sent some gentle and amiable young ladies over, which is a bit seductive.

Moreover, they are also very polite, bowing at every turn.

The gentleness of bowing your head can let you see that there are many things hidden in the ditch.

Look, entanglement, my wife is still in front of me.

Don't look at it, it seems a bit hypocritical.

Of course, Shen Guanglin came back to the capital again, and the Fusang people also made requests.

They did it more implicitly, while praising Shen Guanglin, they appealed: "Professor Shen, give us a lecture too. Shen Sang hasn't given a lecture for a long time."

It is true that Shen Guanglin has not given lectures in Fusang for a long time. He is not short of money, so he lacks the motivation to give lectures.

What's more, Shen Guanglin's value has increased again this time. It used to be 5 US dollars per class, but now it's 8 US dollars, and there are still many people who can't hear it.

Since hospitality is so hard to get rid of, let's hold a lecture. Anyway, there were several lectures held in Citigroup some time ago.

So, the matter of organizing the lectures is left to those young ladies.
Shen Guanglin just needs to take Li Li to play around.

Kyoto in midsummer is also a season suitable for tourism. The two of them are like ordinary couples, leaving a lot of laughter in various scenic spots.

With a beautiful girl by my side, it is suitable to go out at any time.

It's just that the assistant they sent to Shen Guanglin recently is gentle and gentle, but her efficiency is not very good.

It's been a few days before I can arrange the lecture.

In the end, the location of the lecture was chosen in the largest auditorium of Kyoto University.

Moreover, the notice has already been sent out, and the lecture will officially start in three days.

In fact, Shen Guanglin is very familiar with the matter of holding lectures, and he doesn't even need to prepare lessons.

Perhaps, but for biology and medicine, Shen Guanglin's understanding and mastery are relatively poor, and he is still a little timid when he really takes the stage.

But for the application of LED and its products, Shen Guanglin has a lot to say.

Whether it is the discovery process of blue LEDs, the preparation process of gallium nitride, the research and development ideas of white LEDs, or the composition concept of color LED screens.

Any topic can be taught a good lesson.

In short, the content of this lecture is temporarily positioned as talking about LED and its industry. Shen Guanglin didn't seriously prepare the lesson, and he didn't care about what he was going to talk about.

It's really the day when the lecture starts.

What an empty house, what a house full of friends, these are not excessive adjectives.

Shen Guanglin saw many people from other places outside the auditorium, and they were all middle-aged and elderly people, and the rest were some media reporters.

Do you want so many people?Shen Guanglin just gave a lecture, is it such a sensation?
Really, I don't know why, but it seems that scholars from all over Fusang have come.

What about Tokyo, what about Nagasaki, what about Nagoya, everyone probably wants to pay their respects to Professor Shen’s British capital.

This scene made Shen Guanglin feel that his appeal is really strong.

It seems that his status has improved a bit.

Alas, such small scenes in the past could no longer arouse Shen Guanglin's desire to express, but today is different. In today's lecture, the audience in the audience obviously felt that they were more advanced.

Finally, according to the scheduled time, the lecture officially started.

Shen Guanglin carries slides with him, which is one of the lecture tool kits, in case he can use them at any time.

Moreover, this lecture in Fusang also made Shen Guanglin feel that something was wrong.

This feeling was discovered from the moment I entered the venue.

Everyone was very quiet, obviously a group of middle-aged and elderly people, but they still pretended to be students.

This scene made Shen Guanglin feel that it was a bit of a loss for him to charge 8 dollars for a class.

If I had known that there were so many old guys here, I wouldn't even double it.

After all, the knowledge that the old guy and the young guy need to receive is different. The old guy knows better. It is not so easy to gain respect from them.

However, Shen Guanglin was not afraid.

He took out his handouts, and according to his version of the story, he started from Jinmen. His original intention of studying semiconductors was to make photovoltaic panels, starting with monocrystalline silicon and polycrystalline silicon, and later extended to gallium arsenide.

Then, his interest shifted to light-emitting diodes, so Shen Guanglin thought, as long as high-efficiency blue light-emitting diodes can be manufactured, is it possible to make white light-emitting diodes?

Is the white light diode produced in this way more energy-efficient, and the light intensity emitted is brighter?

Do it when you think of it.

Then, gallium nitride was made.

Then, white LEDs were also made.

Then, colored LED tubes were also made.

The content is well-prepared and the time goes quickly.

The familiar content and rich teaching experience made Shen Guanglin feel that this was another successful speech.

Sure enough, when the time passed the predetermined node, there was programmed applause from the audience.

Then it's time for questions.

However, it was during the question-asking session that someone attacked Shen Guanglin.

"Shen Sang, you said that your laboratory was the first to successfully research the blue light diode, right?"

"Of course. Blue light diodes are the basis of white light diodes." Shen Guanglin replied with a smile.

"However, as early as last year, I had discovered a semiconductor substance that can emit blue light --- gallium nitride."

babble?Shen Guanglin was dumbfounded, and asked casually, who are you?
"I'm Shuji Nakamura."

Cut, Li Gui met Li Kui.
