"What do we college students need to do when a country is made up of hundreds of millions of people, and the peasant uncle grows food for everyone to keep people from starvation, the construction worker builds the city so that we have a place to live, and the worker master makes goods so that we can enjoy a better life?

It seems that we will not do anything, but in fact, we have to do everything, we can use knowledge to transform the world, use knowledge to expand agricultural production, use knowledge to build higher buildings, use knowledge to improve productivity, and make better quality goods, this is the essential work of our college students.

But it is not easy to do these well, and a spirit is needed, and that is the spirit of innovation!

There are two kinds of innovation, one is to invent and innovate, to create things that did not exist before, such as Watt's invention of the steam engine, which brought the whole world from an agricultural society to an industrial society, such as Edison's invention of electrical appliances, and brought the world from the age of steam to the age of electrical appliances.

There is also a kind of improvement innovation, that is, the low productivity of the technology to improve, in order to achieve higher efficiency, such as Professor Xiong Huaizhi is leading the staff of Huaxia Industrial Technology Co., Ltd. to study German machine tools, once a breakthrough is achieved, to achieve the localization of advanced machine tools, then our country's industrial level will be instantly increased several times, and many machinery that can not be made before can not be a problem.

Our world is born in the continuous invention and creation and evolution and improvement, with innovation, the world's productive forces will become stronger and stronger, in the future, our farmers will drive automatic harvesters to gallop in the vast farmland to harvest grain, thousands of acres of land and thousands of tons of grain can be harvested in one day; our construction workers will use the latest construction materials to build buildings hundreds of meters high, standing on the roof of the building is enough to overlook the mountains; our workers will control advanced machine tools, manufacture incomparably precise instruments, lead mankind into an unknown territory, explore the latest mysteries, these are to be realized by us intellectuals。

I can tell you with certainty that scientific innovation is the ultimate driving force for the progress of our entire human race, and all people must work around scientific innovation, and we intellectuals must study science, understand science, and then realize innovation, while the national government should ensure the development of science, organize and coordinate the greatest force, so that intellectuals can settle down to innovate, as long as this is the case, a country and a nation will become strong, and those crooked ways, conspiracies and tricks are nothing but ghosts in front of them.

So, how do we innovate scientifically? First of all, we keep learning, and mastering a solid foundation is the foundation of innovation.

Innovation is a process of breaking the stereotype, breaking the original common sense, and sometimes challenging authority.

This requires not only a strong reserve of knowledge, but also a spirit of questioning, the essence of which is loyalty to science, not obedience to authority......... A great scientist must have a strong will, just like Einstein, the whole world does not understand the theory of relativity, but he still discovered the mystery of the universe, this is not accidental but inevitable, because all innovation is like the jewel in the crown, only the best people can step on the peak to pick up that brilliant treasure!"

In this speech, Liu Lang told everyone that as intellectuals, we should maintain the highest reverence for science, what is science? Science is the most objective embodiment of this world, and it will not change with human consciousness.

Why does water freeze and why does the sun heat up? These are all objective laws, and scientists just want to sum up the objective laws in nature, and the objective laws exist there for eternity, just waiting for people to discover them.

But discovering these laws is not an easy task, and it requires scientists to have a strong will, and sometimes even face threats to their lives, such as Bruno, who was burned alive by the church in order to defend heliocentrism.

Such things seem absurd in the eyes of modern people, but in fact they happen all the time, for example, if your research conflicts with some authoritative figures, it will cause losses to the other party, and it is likely to be suppressed by authoritative figures, what should you do in this case?

So that's where you have to be determined.

After Liu Lang finished speaking, the students in the auditorium burst into the warmest applause, mixed with cheers, they are all students, and they are college students after the reform and opening up, and they have formed their own values after the impact of some foreign ideas, the core of this value is freedom and equality, and these concepts coincide with Liu Lang's concept of not being afraid of authority.

The applause lasted for several minutes.

"I know why you applaud, because we are all hot-blooded young people who want us to be freer......... I am the same, but in my heart, the basis of freedom is not to let go of something, but to the construction of legal equality, a fair society is the standard for a country's strength, our country is now in the early stage of reform and opening up, there are various problems, which takes time to build, not a handful of formation, just think of ourselves, in the process of growing up made a lot of mistakes, these mistakes let us sum up the lessons, and then improve themselves, the same is true of the country, when he finds his mistakes, if he does not make changes, then he will also be punished………。

I always wonder what kind of world the future holds.

In terms of science and technology, with the continuous development of science and technology, there will be a large number of new things in front of us, ten years from now we need 50 percent of the things we need have not yet appeared, 20 years from now 100 percent of the things, we don't know now, for example, cars, there will be cars in the future, but at that time cars no longer need people to drive themselves, cars can be autonomous, through the sky of communication satellites for real-time guidance.

The future buildings will be four or five hundred meters high, and thousands or even tens of thousands of people will live and work in one building, and the use of space will be maximized.

The future of communication is beyond our imagination, we play around with a small phone in our hands, the signal is transmitted by satellite, and even friends in the United States can immediately answer my call and communicate in real time!

At that time, the whole world was connected by advanced science and technology, we can know what happened in the United States in an instant, and in the same way, all kinds of information about our country will be immediately known by foreign countries, and human beings at that time have been integrated by technology, and the distance between hundreds of countries is no longer out of reach, and the situation can be summarized in one word, that is, the global village, our earth has become a village, and when someone in China shouts, Americans can hear it immediately.

And the country will also change under these powerful technological shocks, the so-called ideology has become unimportant, people only care about whether they live a better life, this development is the general trend can not be resisted, and many people here can see the arrival of this general trend.

All of us must look forward, what we do must also move forward, to contribute to the development of this world, rather than to make a behavior against the development of the world, as long as we control the trend of world development, we will become a trendsetter, and endless scenery will gradually appear in front of us.

All of us are at the juncture of a great historical process, and the next 30 years will be far more wonderful than the sum of the previous thousands of years, so I hope that all of you here can keep up with the pace of the times, stand on a high place to appreciate the style of the great era, time flies, when this era enters the 21st century, we look back at the present, then we will find how ridiculous and naïve our thoughts are now, I hope that at that time, we will sit together again and reflect on everything that happened in these years, which will be the best twenty years of our short life, not a bitter memory！”
