In view of the fact that he was going to the United States again around May, Sun Yuanqi immediately set about writing a science newspaper after finishing writing a science newspaper.

If Sun Yuanqi only played a role in helping idlers in the compilation of the first issue of the Journal of Private Jingshi University in the liberal arts, then in the second issue of the publication of science and engineering journals, he was definitely the main force of the first class. From planning, topic selection, manuscript commissioning, to reviewing, revising, finalizing, to cataloging, proofing, and typesetting, everything must be done personally.

In addition to inviting Einstein to write for the journal, students from all departments of the school were encouraged to write papers on the problems encountered in their study and life, such as "A Brief Discussion on the Relationship between Water Flow Speed and Thermal Attenuation" written by students of the Department of Physics, which is a practical problem encountered in the process of erecting heating in the Chengke Pavilion. To keep the temperature of each room in a stable and comfortable range, the speed of hot water must be appropriate, otherwise it will waste resources, and it will not be even hot and cold, and the desired effect will not be achieved. Through simulated experiments and actual use, the students gave a curve of the relationship between water flow velocity and thermal attenuation, which fit well with the actual measurement. This lays a good theoretical foundation for the laying of heating pipes on the whole campus in the future.

For example, the "Discussion on the Analysis Method of Hazardous Substances in Tap Water" of the Department of Chemistry and the "Pros and Cons of DC and AC in Hydroelectric Power Generation" of the Department of Electronics are all for the same purpose.

Compared with the group battles of the three departments of physics, chemistry, and electronics, the Department of Mathematics is the eight immortals who cross the sea and show their magical powers. Zhang Chun's "Western Expressions of Ancient Chinese Calculations", Zhou Da's "New Solutions to Several Calculus Problems", and Hu Dunfu's "Theory of Straight Integral Differential Equations" were all written according to their own interests, each with its own strengths.

If the students' papers are still a little immature, then two articles of IPRT are enough to establish the leading position of the Journal of Private Jingshi University in China and even East Asia: one is "Reflections on the Limitations of the Theory of Relativity" co-signed by Einstein and Mileva, which delves into the nature of gravity and pays attention to the relationship between inertial mass and gravitational mass, which in a way has opened a window to general relativity. There is also an article that Sun Yuanqi has been planning for a long time: "The Concept of a Cyclotron Particle Accelerator".

When it comes to particle accelerators, ordinary people are still a little unfamiliar, but in real life, they are very popular. For example, big-butt televisions and computer monitors (i.e., CRT monitors) and X-ray facilities are all small particle accelerators.

Particle accelerators have been indispensable in scientific research since the twentieth century: they have discovered most of the new transuranic elements, synthesized thousands of new artificial radionuclides, and with it, they have systematically and deeply studied the basic structure of the atomic nucleus and its change laws, which has promoted the rapid development and maturity of nuclear physics; The development of high-energy particle accelerators has led to the discovery of hundreds of particles, including baryons, mesons, leptons, and various resonance particles, and the establishment of particle physics. In the fields of engineering, agronomy and medicine, accelerators are used in isotope production, tumor diagnosis and treatment, radiation disinfection, non-destructive testing, polymer irradiation polymerization, material irradiation modification, ion implantation, ion beam microanalysis, space radiation simulation, nuclear explosion simulation, etc. Especially in the past 20 years, the application of accelerators has far exceeded the fields of nuclear physics and particle physics, and has also been widely and importantly used in other scientific and technological fields such as materials science, surface physics, molecular biology, and photochemistry.

In fact, since Sun Yuanqi announced the so-called "alchemy" in 1900, that is, the first artificial transformation of nitrogen atoms by bombarding nitrogen atoms with α rays emitted by natural radioactive elements, physicists have realized that in order to further understand the structure and change laws of atomic nuclei, it is necessary to bombard atomic nuclei with high-speed particles. However, natural radioactivity provides limited particle energy, only a few megaelectron volts; Although the energy of particles in natural cosmic rays is very high, the particle flow is extremely weak, for example, particles with an energy of 10 to the 14th power electron volts only arrive on average one per square meter of an area on average, and they cannot control the type, quantity, and energy of particles in cosmic rays, so it is difficult to carry out research work. Therefore, in order to achieve the desired goal of experimental research, the development and construction of particle accelerators has become very important.

Scientists originally conceived the idea of using linear accelerators to accelerate charged particles, which move along a near-linear orbit and are accelerated step by step. However, when very high energy is required, the straight-line distance of the accelerator can be very long. What can be done to drastically reduce the size of the accelerator? In 1930, Ernest Lawrence, a graduate of Yale University, was inspired by the working principle of resonant acceleration of linear accelerators and proposed the development of cyclotrons. It is to add two semicircular magnetic fields in the cyclotron, so that the charged particles no longer move in a straight line, but move along an orbit similar to a plane spiral, so that the electric field of the accelerator will not be too long to cause the loss of electric field energy, and it can also be accelerated to a very high energy by resonance step by step, and the size of the accelerator is also greatly reduced. For this invention, Lawrence was awarded the 39th Nobel Prize in Physics.

In the article "The Concept of a Cyclotron Particle Accelerator", Sun Yuanqi put forward this highly conceived design invention.

In addition, Sun Yuanqi also undertook the difficult task of writing a frontispiece for this science newspaper. In a sense, Sun Yuanqi regarded this text as more important than any paper in the journal. Because it is not only the purpose of the journal in the future, but also the most direct impression of readers on the journal. Is it propaganda and agitation, shouting the slogan "science and technology are the primary productive forces"? Or is it about the latest scientific advances in the world right now, so that readers can breathe and share the fate of the scientific community?

After much hesitation, Sun Yuanqi decided to write the wish that he wanted to do the most, had been doing, and was difficult to complete independently.

As a result, when readers awkwardly open the science edition of the "Journal of Private Jingshi University", they will see the following title: "The Direction of China's Natural Science Research - Discussion with China's Aspiring Science and Technology Savers". In the article, Sun Yuanqi solemnly wrote in the vernacular that orthodox scholars very despised:

Since Daoguang and Xianfeng, the overall backwardness of China's natural sciences is obvious. As the Western calendar entered the new century, this gap not only did not narrow or disappear because of the vigorous development of the Westernization Movement, but also became wider and wider. The gap is getting wider and wider, and it is related to the rise and fall of the country and the rise and fall of the nation.

A scholar once said that all great theories and ideas are conjectured. Reasoning and argumentation based on existing theories can only lead to some conclusions and opinions within the framework of existing theories. The students in China's primary and secondary schools are generally very intelligent, and they are rarely bound by the existing theoretical knowledge, and they are older and more mature than the students of Europe and the United States, so they may really be able to come up with something great. However, these great things cannot bring benefits to the country and the nation for a while, and in addition to increasing honor, they have little to do with the rise and fall of the country and the rise and fall of the nation. Therefore, we should pay more attention to practical scientific research.

Of course, it is undoubtedly a fool's dream that only a small number of natural science researchers in China want to fully blossom and catch up with each other in the field of natural sciences. The desirable method is to carry out in-depth research at one or a few narrow points, and then make breakthroughs, and to achieve all-round development by promoting the improvement of the level of natural science research from point to point.

Although I am not talented, I have traveled to the West for many years and have seen a little. Today, I am here to put forward three directions that China's natural science research urgently needs to pay attention to, and discuss with those who are interested in saving the country through science and technology in China. If there is any advantage, I hope everyone will work together for this!

The first is scientific research related to increasing agricultural production and income. China has been a large agricultural country since ancient times, and the number of people engaged in agricultural labor is also the largest in the world, but 40,000 people work hard every day, but they still struggle with insufficient food and clothing. People with lofty ideals are all sad! Therefore, scientific research related to increasing agricultural production and income is the first priority of scientists. Here is a reminder to all of you, please don't think that the art of farming, the Chinese people have thousands of years of experience, so they take it lightly. You must know that if you want to get a bumper harvest of crops alone, it must involve ecology, hydraulic engineering, genetics and breeding, soil and water conservation and desertification control, pest control, agricultural machinery, pesticide science, soil science, plant nutrition and many other disciplines, which is enough to make countless scholars devote their lives to it. What's more, there are also animal husbandry, breeding, fishing, tea making, fruit trees and other categories?

The second is scientific research related to the establishment of the industrial system. Since the Westernization Movement was launched in the north and south of the great river, China's industrial system has been initially established, and certain achievements have been made in coal mining and iron and steel smelting. However, on the whole, it is still very weak, especially in geology, mineral exploration, mining engineering, safety technology, metal metallurgy, material processing, machinery manufacturing, etc., far behind Western countries. A complete and healthy industrial system must be supported by solid and rich scientific knowledge, guided by active research and exploration, in order to ensure sustainable development. Only caring about importing and transplanting from foreign countries can only be regarded as parroting, and after all, it cannot be independent.

The third is scientific research related to military warfare. If there is no sufficient force to ensure the increase in agricultural production and income and the establishment of an industrial system, even if great achievements are made, they will only be slaughtered by others. Therefore, scientific research related to military warfare has always been the focus of research by scientists in various countries. The study of advanced and efficient firearms, weapons and equipment is the top priority. At a time when China's industrial system was not yet fully established, the study of military products was similar to seeking fish from a wood. However, we can take a different approach and study one or more superweapons with strategic deterrent significance. This kind of super weapon has a powerful lethality that ordinary weapons do not have, for example, it can destroy thousands of enemies at a time, so that they will not dare to attack, and achieve the goal of surrendering without a fight.

As a comprehensive university with the purpose of applying the world to the world, strengthening the country and benefiting the people, and focusing on the cultivation of academic and scientific research talents, teaching faculty of other schools, and technical strength of enterprises and institutions, Jingshi University is interested in making its own contribution in these three aspects. I hope that the majority of readers will learn from each other and make progress together, so as to achieve the goal of the situation of the motherland and the prosperity of the people.

Many scholars in the history of science and technology believe that the publication of this article marks a major shift in the research interests of this outstanding master of physics, and the beginning of the shift from theoretical research to practical technology. Since then, the development of physics in China has entered a new stage!

Sun Yuanqi didn't think much about it at this time, but he was eager to tell the future scientists of his motherland about his wishes, hoping that they could work with him to change this poor and backward country.

After finishing writing, Sun Yuanqi still felt dissatisfied, and was about to change it again, Lao Zheng staggered into the house, forgot to knock on the door, and shouted in a straight voice: "Master, something is wrong!" ”;
