Xia Lao is 72 years old this year and is the first batch of members of the Chinese Academy of Sciences, and later the members of the department were renamed academicians.

She successively studied under Hua Luogeng in the Institute of Mathematics and Qian Sanqiang in the Institute of Modern Physics, and under the leadership of the two great bulls, she participated in the preparation of the first computing institute in China, and finally presided over the successful development of the first general-purpose electronic digital computer 107 in China in 1960.

At that time, the birth of the 107 machine was just in time, and immediately after its inception, it played a huge role in various cutting-edge fields of science and technology, such as artillery trajectory calculation, atomic reactor ray energy distribution calculation, matrix eigenvalue and eigenvector calculation in atomic nuclear structure theory, and blast wave propagation calculation.

After that, Xia Lao began to shift his focus to computer teaching, which has been a peach and plum for decades.

Xia Lao sat down in the conference room and immediately said: "I don't want to make a special trip, the Ministry of Education has a meeting today, and I brought two graduate students to participate, remembering yesterday's paper, by the way, come and ask." I heard it was written by a junior high school student?"

Speaking of this, Xia Lao nodded and continued: "This paper is really not simple. Yesterday, in the Institute of Computing, several graduate students I took with me were looking through this paper and asking me, and when I looked at it, they asked them to verify it at that time, and the results were very good. A few of them stayed up all night, and there was no problem at all, and today they are going to use Intel's 486 to build a model to try. ”

Dai Xinfang said: "Things are good things, but because the author is too young, we really don't feel at ease, so we sent them to calculate and verify." ”

Xia Lao smiled: "I don't mean to force you, but I heard that if you win the first place in this competition, you can go to Beidu to participate in the awards, and I want to meet that student in Beidu." ”

When Dai Xinfang heard this, he thought: "Well, you are not called coercion, you have already made up your mind." ”

Shen Juan asked cautiously: "Do you want to wait for the results of the model verification to come out?"

Xia Lao shook his head impatiently and said, "Don't study it, this paper is fresh even to me, where to copy it." I read so many papers every year, but I have never seen such an algorithm and system design, who has the leisure time to write it hard, but use it to participate in the science and technology competition for middle school students? How many people have tried their best to become a professor, but they are short of such a weighty paper. So I said, a grand prize is more than enough. ”

Zhang Lian said: "That's it. Thank you, Mr. Xia, for your attention to the computer project of our National Science and Technology Competition for Middle School Students. I couldn't agree more. ”

Dai Xinfang was right when he thought about it, and suddenly felt that his eyes suddenly brightened, and said with a smile: "Old Xia, look at my brain, you woke me up with a word, this is indeed the reason." ”

Hearing this, Xia Lao stood up with a smile, waved his hand as he walked out, and said, "Don't be a sycophant, I didn't bring you sugar, I'm going back, and the two students are still waiting for me outside." ”

The three of them hurriedly sent Xia Lao out of the door, and watched Xia Lao leave with the two graduate students of the Chinese Academy of Sciences who were guarding the door she brought.

When Hu Yiting returned to Hushan, it was already Saturday evening.

After Hu Yanan took his son home, the two had a long talk that night.

"The song you write can sell for more than 10,000 yuan?"

"Eight songs, each with 900 words and 900 songs, a total of 14,004. ”

Hu Yanan felt that the amount of information was a bit large, frowned and thought for a while: "When your mother called me yesterday, I couldn't believe it, I didn't expect the money in the south to be so easy to earn." ”

Hu Yiting said: "It's not so easy to earn, the SAR is not prosperous 9 to 5, the workers work day and night, the businessmen don't work in vain and black, and the shops get up early and are greedy for business, and they earn hard money." ”

Hu Yanan said: "What kind of Huachuang are you talking about, I have also heard of it, and our daily newspaper has also published their advertisements. Do they really give you five million just to buy your patents?"

Hu Yiting said: "It's not to buy a patent, it's a patent fee, and the money will not arrive until the tape-out is successful and the order is officially placed." ”

Hu Yanan was puzzled: "Where did you learn electronic technology? I remember that you didn't even know how to repair a radio before, so you still took it outside to find a maintenance department to spend money to repair it." ”

Hu Yiting said far-fetchedly: "That's not the same, you are a newspaper editor, do you know how to repair the printing press?"

Hu Yanan shook his head, feeling a little wrong, but he couldn't say what was wrong, so he had to say: "Of course it's good that you can be self-taught, but you can't go to school, right? ”

Hu Yiting said: "I promise you, every exam in the future will be in the top five of the grade, this is always okay, right? But you must support my work and help me get a long-term sick leave, and if it is not the end of the semester exam, I will not go to school to waste time." ”

Hu Yanan said: "You can really do it, I have no opinion, but when I listen to this, how can I feel so unreliable?"

Hu Yiting said: "Your son is a genius, you are not happy? ”

Hu Yanan said: "Don't pour me into the soup, in short, if you fall behind in your grades, you have to go to school for me." ”

Hu Yiting said: "Then it's decided, you and I will go to the top floor of Hushan Mall tomorrow to buy two monitors and come back, as well as the peripherals such as keyboard and mouse, and you also have to buy a hundred floppy disks." ”

Hu Yanan said: "How much does it cost?"

Hu Yiting said: "It should be within 5,000 yuan, and you can bring 6,000 yuan." ”

Hu Yanan was startled, and said in pain: "It's so expensive! Your mother wants a big color TV, and I haven't been willing to buy it for so long, it's good for you to buy two big computers! Tell me, how much do you cost to bring back those two cases?"

Hu Yiting said honestly: "The two add up to more than 36,000 yuan. ”

Hu Yanan's eyes darkened: "It's so expensive? People are willing to give it to you? How dare you ask for it? You won't be a liar, right?"

Hu Yiting said: "If you don't understand computers, don't worry so much." People are willing to give, just believe that I can afford it, outsiders believe in me, and you still don't believe me?"

Hu Yanan sighed and said: "Hu Yiting, you are too good at tossing, the savings of my life can be regarded as being taken into it by you." You can cherish this computer for me, use it well, don't break it, in case something goes wrong, we'll send it back as it is. ”

On Sunday morning, Hu Yanan first took Hu Yiting to the bank to withdraw money, and found that there was an extra 10,000 yuan in the account, and the remittance note was Bai Ping.

The two came to Hushan Mall, bought two 14-inch Great Wall monitors on the top floor, equipped with keyboards, mice and floppy disks, and after bargaining, they spent 5,000 yuan.

Hu Yiting said: "Dad, I've bought everything, I can't put it without a place, I have to have a big table." ”

Hu Yanan said: "Your house is so small, where can you buy a computer desk?"

Hu Yiting said: "The computer desk is so small, you have to buy two to put it down." ”

The name of this store is Great Wall Computer, and the boss's business card is printed with Yang Huaiyuan.

Boss Yang Huaiyuan heard the two say this, and was surprised: "You have two computers at home?"

Hu Yiting said: "Yes, but it would be too ugly to buy two computer desks." ”

Yang Huaiyuan said with a smile: "That's the same, otherwise, what do you think of my monitor bench? It's no problem to put two computers and two cases, if you don't feel too old, just take it, the price is negotiable." ”

Hu Yiting took a closer look at the long table where the monitors were placed in the store, and saw that it was made of solid wood, painted with white paint, and four monitors side by side were more than enough.

"How much?"

"When I opened the shop last year, I found a carpenter, and it didn't cost much. Now there are too many goods in the store, and they are almost full, and it is troublesome to turn around. This shelf takes up too much space, and the display of the monitor is also dusty, so you can watch it. ”

Hu Yanan hurriedly said, "Fifty." ”

Yang Huaiyuan said with a smile: "This uncle, you are really good at business, such a big platform is only fifty? Don't you look at how thick and strong this wood is, and there are eight anti-deformation triangle braces next to the four legs." ”

Hu Yanan said: "No matter how strong it is, it's old, you don't need it, and it will take up space in the store, and fifty will be counted for us." ”

Yang Huaiyuan smiled bitterly: "Yes, fifty is fifty, everyone plays with computers, and I will take care of my business more in the future." If you can buy two computers at home, you must be a professional, and if you introduce more friends in the circle in the future, I will be content. ”

Hu Yiting said: "Okay, that's it, I will definitely take care of your business in the future, and I will have your benefits." But you're too big to move. ”

Yang Huaiyuan heard Hu Yiting's tone loud, smiled bitterly and wiped his sweat and said: "Otherwise, you give me an address, and when I close the store at night, I will send it to you, I have a three-wheeler downstairs, which is convenient." ”

Hu Yiting said: "Then why don't you help me send it now, I will carry these two dead old-fashioned CRT monitors all the way back, this is not LCD." ”

Yang Huaiyuan said confusedly: "What LCD?"

Hu Yiting knew that he was speechless, and said, "Do me a favor, you can run now." ”

Yang Huaiyuan was also refreshed, and after a little thought, he agreed, and asked his wife to stay and watch the store.

So Boss Yang carried the table, Hu Yiting and his father picked up a monitor, and the three of them went downstairs.
