    Since he was going to the United States again around May, Sun Yuanqi immediately started writing a science journal after finishing writing a journal on liberal arts.

    If Sun Yuanqi only played a supporting role in the compilation of the first issue of "Journal of Private Jingshi University" in liberal arts, then he was definitely the first-class main force in the publishing process of the second issue of "Journal of Private Jingshi University" in the field of liberal arts.  From planning, selecting topics, requesting manuscripts, to reviewing, revising, and finalizing manuscripts, to cataloging, proofreading, and typesetting, everything must be done personally.

    As for planning the topic, in addition to inviting Einstein to write articles for the journal, students from various departments of the school were also encouraged to write papers on problems encountered in study and life, such as "A Brief Discussion of Water Velocity and Thermal Attenuation" written by a group of physics students.  "Relationship" are the practical problems encountered during the installation of heating in Chengqi Hall.  To keep the temperature of each room in a stable and comfortable range, the speed of hot water must be appropriate, otherwise resources will be wasted and the heating and cooling will be uneven and the desired effect will not be achieved.  Through simulation experiments and actual use conditions, the students gave a relationship curve between water flow velocity and thermal attenuation, which fit well with actual measurements.  This will lay a good theoretical foundation for the future laying of heating pipes throughout the campus.

    Another example is "A Preliminary Discussion on the Analysis Methods of Hazardous Substances in Tap Water" published by the Department of Chemistry and "On the Advantages and Disadvantages of DC AC Hydropower Generation" published by the Department of Electronics, both for the same purpose.

    "Compared to the group operations of the three departments of physics, chemistry, and electronics, the mathematics department is like the Eight Immortals crossing the sea, each showing its magical powers.  Zhang Chun's "Western Expression of Ancient Chinese Arithmetic", Zhou Da's "New Solutions to Several Calculus Problems", and Hu Dunfu's "The Theory of Straight Integral and Differential Equations" were all written based on their own interests and each has its own strengths.

    If the students' papers are still a bit immature, then the two articles of iprt are enough to establish the leading position of "Journal of Private Economics University" in China and even East Asia: one is co-signed by Einstein and Mileva  "Thoughts on the Limitations of the Theory of Relativity", the article deeply explores the nature of gravity and notes the relationship between inertial mass and gravitational mass. From a certain perspective, it has opened a window to the general theory of relativity.  There is also an article that Sun Yuanqi has been planning for a long time: "The Concept of a Cyclotron Particle Accelerator."

    Speaking of particle accelerators, ordinary people are still a little unfamiliar with them, but in real life, they are very common.  For example, big-ass TV sets, 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 relied on them to conduct systematic and in-depth research  The basic structure of the atomic nucleus and its changing laws have led to the rapid development and maturity of nuclear physics; the development of high-energy particle accelerators has enabled people to discover hundreds of particles including baryons, mesons, leptons and various resonant particles, establishing the  of particle physics.  In various fields of engineering, agriculture, and medicine, accelerators are used for isotope production, tumor diagnosis and treatment, radiation sterilization, non-destructive testing, polymer radiation polymerization, material radiation modification, ion implantation, ion beam microanalysis, and space radiation  Simulation, nuclear explosion simulation, etc.  Especially in the past 20 years, the application of accelerators has gone far beyond the fields of atomic 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, photochemistry, etc.

    In fact, ever since Sun Yuanqi announced the so-called "alchemy" in 1900, that is, using alpha rays emitted by natural radioactive elements to bombard nitrogen atoms to achieve the first artificial transformation of elements, physicists have realized that in order to further understand the structure of atomic nuclei and  To change the law, high-speed particles must be used to bombard the atomic nucleus.  However, the particle energy provided by natural radioactivity is limited, only a few trillion electron 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 of electron volts, average at  Only one falls on an area of ??one square meter, and the type, quantity and energy of particles in cosmic rays cannot be controlled, making it difficult to use for research work.  Therefore, in order to achieve experimental research with expected goals, it is very important to develop and build particle accelerators.

    Scientists¡¯ initial idea was to use a linear accelerator to accelerate charged particles. The particles would move along a nearly straight track and be accelerated step by step.  However, when high energy is required, the linear distance of the accelerator will be very long.  What methods can be used to significantly reduce the size of the accelerator?  In 1930, Ernest Lawrence, a graduate of Yale University, proposed the development of a cyclotron, inspired by the working principle of resonant acceleration of linear accelerators.  It is to add two semicircular magnetic fields in the cyclotron, so that the charged particles no longer move along a straight line, but move along an orbit that is approximately a planar spiral. This modification makes the acceleration?It has powerful destructive power that ordinary weapons do not have. For example, it can destroy thousands of enemies with one use, making them frightened and afraid to attack, achieving the purpose of defeating others without fighting.

    Jingshi University, as a comprehensive university with the purpose of managing the world and strengthening the country and benefiting the people, and focusing on cultivating academic and scientific research talents, teaching faculty in other schools, and technical strength in enterprises and institutions, is determined to be the best in these three aspects.  Make your own contribution.  We hope that readers will learn from each other and make progress together with us, so as to achieve the goal of making the motherland and the people prosperous.

    Many scholars in the history of science and technology believe that the publication of this article marked a major change in the research interests of this outstanding master of physics, 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 at this time, he just eagerly wanted to tell the future scientists of his motherland 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 when he was about to make some changes, Lao Zheng stumbled into the house, forgetting to knock on the door, and shouted at the top of his lungs: "Master, something big has happened!!"
