Chapter 676 Mutual Encouragement
Beijing Institute of Technology is not affiliated with the Ministry of Education. As one of the "Seven Sons of Military Industry", it has always been affiliated with the military industry system, and now it is affiliated with the Ministry of Machinery and Electronics Industry.
It is one of the earliest universities in China to have a computer room and set up computer-related majors, and its computer professional capabilities have always been top in the country.
In aerospace, materials, electromechanical, machinery, optoelectronics, automation, computer, software and other majors, Beijing Institute of Technology is the best in the country.
Being a student of Beijing Institute of Technology is undoubtedly happy. Because in addition to the monthly subsidies from the state, the school also gives students a living allowance, so that students can study without worries, and even save some money and send some money to their families to subsidize household expenses.
Moreover, students of Beijing Institute of Technology have many choices. They can choose to go to Panshan Group, the Ministry of Machinery and Electronics Industry, or military factories and military scientific research units.
Among the many choices, it is undoubtedly proved that going to the ministry is not the best choice, and going to Panshan Group is the best choice.
It’s just that not everyone can go to Panshan Group, but only graduates with excellent character and academic performance can go.
The number of places is limited, so any student who has something to pursue will often work hard to study seriously.
While the students were discussing in low voices, the host came on stage in the auditorium. Under the control of the host, the whole auditorium became quiet and everyone stopped whispering.
"Now let us invite Professor Liu Tao to give us a unique lecture on the theme of "The Development and Future of Computers."
As the host finished speaking, warm applause rang out in the auditorium, welcoming Liu Tao.
Liu Tao walked out from the backstage and waved to everyone. He walked to a table and connected the projector to his laptop. Then he saw that the projector changed when it was projected on the screen. A strange item appeared on the big screen - counting sticks.
Liu Tao talked about the development of computers. He first talked about the invention of counting sticks in China in the late Spring and Autumn Period and the early Warring States Period, and the invention of abacus in the 5th century BC.
These are all manual calculation tools.
"In 1623, German scientist Chickard created the first mechanical computer in human history, which can perform addition, subtraction, multiplication and division of six-digit numbers." Liu Tao pressed a button, and the first mechanical computer in human history appeared on the big screen. It was very simple and did not look like a modern computer at all.
"In 1624, French mathematician and physicist Pascal invented a mechanical adder, which solved the key problem of automatic carry. In 1974, German mathematician and philosopher Leibniz designed a multiplication automatic computer and proposed the important idea that "mechanical arms can be used to perform tedious and repetitive calculations on behalf of people."
This is the development process of the entire computer!
Everyone clearly saw the evolution of computers.
Then they saw that the computing power of a small computer now far exceeded those giant computers thirty or forty years ago.
Liu Tao introduced the development of personal computers, including desktop computers and laptop computers.
These are currently in a very fierce competition. Major computer manufacturers are constantly upgrading their technology and launching new desktop and laptop computers.
The development speed of personal computers is very fast, and the performance improvement is also very rapid.
When talking about personal computers, we have to mention Jinlong Computer, which is currently the world's largest computer manufacturer and firmly occupies the first place in market share.
In 1986, Jinlong Computer defeated IBM to win a huge order of 480 million US dollars from the US Air Force. In 1987, it defeated its competitors again to win a huge order of 890 million US dollars from the US Army.
In terms of desktop computers, the prices are also very different, ranging from 500 to 15,000 US dollars. Laptops are generally more than 3,000 US dollars, and the highest ones even reach 100,000 US dollars.
At present, China accounts for 62% of the world's computer market share!
If it were not for the protection of some policies in the United States and Japan, this market share would increase to 70%!
"The development of computers in the future will continue to keep changing with each passing day, and laptops will become more and more common. Maybe in ten years, every college student will have a computer, and in twenty years, every college student will have a laptop!" Liu Tao made a fantasy prediction.
Although no one believed this, it did not prevent everyone from giving Liu Tao applause.
Many people don't know the history of computer development, but Liu Tao's slow talk has given everyone a clear understanding of the history of computer development.
Then, Liu Tao finished his speech and entered the exchange session.
The first person to get the chance to ask questions was a very gentle girl who was sitting on the floor in the first row. When she saw that she got the first chance to ask questions, she couldn't help but get excited and stood up immediately: "Dear Professor Liu, I am confused now. I think China has many problems. Our cadres are corrupt at an alarming rate. Our national quality is not good. Our compatriots are ignorant. Is there any hope for China?"
"Then I want to ask you, do you think China has developed rapidly since the reform and opening up?" Liu Tao did not answer directly, but asked back.
"Fast, it has developed very quickly!" The girl answered without hesitation.
"Yes, China has developed very quickly after the reform and opening up, which shows that we are on the right path. We are now much better and stronger than we were ten years ago!" Liu Tao nodded and said, "Here, I give you a word, and also to everyone present."
"If you think the motherland is not good, you should build it. If you think the government is not good, you should take the civil service exam and go into politics. If you think the citizens' quality is not good, then start with yourself and become a high-quality citizen. If you think your compatriots are ignorant, then start with yourself and change the people around you. If there are shortcomings, correct them together instead of just scolding and complaining!" Liu Tao said in a resounding voice: "Don't ask what this country can do for you first, ask what you have done for this country first!"
As soon as Liu Tao finished speaking, the applause in the entire auditorium sounded like a storm, like waves one after another rushing towards Liu Tao.
Countless people showed excitement, as if they were injected with chicken blood, as if they were no longer confused, and countless motivations surged in their hearts.
Liu Tao was also very excited when he saw this group of excited people, because he saw hope and saw that this career had a constant influx of fresh blood.
His belief in China has never wavered, because he has experienced it personally, and he knows that China is on the right path. But he knows that for those who have not experienced all this, facing more and more European and American information, coupled with the dissemination of some public intellectuals, it is easy to have self-doubt, and thus blindly worship Europe and the United States and deny themselves.
