When you say it, you have to do it, this is the creed of Junxin. So even though he knew that he was being used by Principal William to some extent, he was the same.

Of course, Junxin knew that there was a reform that Principal William wanted to reform the somewhat rigid Princeton teaching system, but Junxin really couldn't resist the temptation to take on the task.

But since it's next, it's natural to do it well. Therefore, during the holidays, in addition to translation, most of the rest of the time is used to prepare textbooks for class.

Strictly speaking, the comprehensive course of mathematics required by President William was the first time in a university of this era, because it involved a lot of knowledge in various disciplines, so it was quite difficult to prepare this material in less than a month. Even if Junxin has a golden finger in his hand, there are still a lot of things to prepare. It took up most of his vacation. Even his nineteenth birthday was almost forgotten. If Gu Mengxue hadn't accompanied him to make preparations every day, and reminded him when New Year's Day came, maybe his birthday would have passed like this in a daze.

According to President William's suggestion, Junxin needs to integrate a lot of things, with mathematics as the center, including physics, chemistry, computer science and biology and other core disciplines in today's world. Junxin is not worried about physics, chemistry, computer science and other universities, but for biology, Junxin is a little bottomless. Although there is a lot of cutting-edge research on biology in his brain, in the end, he has not received systematic biology training, and what he has mastered has a feeling of being in the air. If you look at the current accumulation of biological knowledge, you may not be able to deal with the biological problems raised by the large group of elite students in Princeton, although Junxin can solve most of the problems by mathematical modeling.

Therefore, when it comes to querying documents and information, in fact, most of Junxin's time is spent on consulting biology-related materials, and most of them are quite basic biological materials.

Junxin's memory is very good, and his memory has brought him great help. It took less than a month to completely read all the basic biology materials and combine them with the memory in his brain to understand, and he had a deep understanding of biology.

In fact, of all the natural sciences, biology is the easiest one to get started. In the circle of scientists, the circle of biology is also the largest, and the reason is very simple, that is, because it is relatively easy to get started in biology, there are many people who can achieve high achievements.

Generally speaking, in the circle of scientists, the circle of mathematics is the smallest, then physics, then chemistry, then computer science, and finally biology, and the circle is the largest. The number of people in the mathematical circle is about a fraction of that of biologists.

However, the low threshold does not mean that the difficulty is low, at least the high-end technology at the frontier of biology is low. Correspondingly speaking, although the genes, signaling pathways, and genetics of the 80s are rotten in 30 years, they are stacked by tens of thousands of biologists who have done one topic after another. Again, this is the biggest reason why there is almost no leap forward in the development of biology.

For any two disciplines, if you want to do an in-depth study of their inner workings, then the most essential thing is to think about problem solving. Only the way of thinking is the key to the intrinsic connection between the different disciplines. To put it simply, a physicist may not know a biologist's conclusions, but he can judge whether the conclusions are correct by understanding the biologist's thinking plan when solving the problem.

The more he understands the inner workings of biology, the more interested Junxin is in biology. Some people say that the twentieth century was the heyday of physics, and the successive creation of quantum mechanics and the theory of relativity created an unprecedented prosperity in physics. Then the 21st century is the heyday of biology. The completion of the human genome project and the establishment of various gene libraries have led to an unprecedented prosperity in biology, and its development is no less prosperous than in the new era of physics in the early 20th century.

Perhaps Junxin is not so familiar with the study of biology, and even a master's degree with three years of postgraduate training may surpass Junxin. However, when it comes to understanding the prospects for the development of biology, then I am afraid that no one in the world today can catch up with Junxin. All kinds of instruments and equipment, all kinds of experimental methods and extended experimental systems and biological tools, no one knows better than Junxin. For example, it was not until 86 years that the simple biology technology and the PCR technology of the instrument that changed the course of biological development appeared, the discovery of cell stemness in 84, and the green fluorescent protein labeling technology of the famous Chinese scientist Professor Qian Yongjian.

Therefore, if Junxin really wants to study biology, then these technologies are not a very difficult thing for Junxin. After all, the development process and application of these technologies in his brain are clearly written, even if he doesn't know the reason, he can do it according to the script, not to mention that he used his ability to systematically study biology?

After making up for the shortcomings of biology, Junxin also has a certain idea of the teaching materials used in the preparation of the lesson. After referring to the textbook of the comprehensive mathematics course he studied in Princeton, Junxin continued to improve the lesson plan in his hand, deleting and modifying until the end of January, when the next semester was at the beginning, a rough textbook was finally completed.

After the completion of the lesson plan, Junxin was not satisfied with the little resources in his hands, so after finding Principal William, he applied to Principal William for a genetic research laboratory, on the grounds that he was not very familiar with biology and needed to verify some of his ideas through experiments.

Fortunately, at this time, a professor from the School of Biology transferred to Harvard University to teach, leaving behind a small comprehensive biology laboratory, President William decided to temporarily transfer the use of this laboratory to Junxin after thinking about it again and again, through the proposal of the professors' association, so after getting a teaching position, Junxin got a laboratory of his own for free.
