Obviously, it is impossible for China to import the required materials and processes from the UK, and Hu Weidong estimates that it will take at least 30 years to do all the research on his own (Note 1), which is too long. Therefore, Hu Weidong resolutely decided to skip the steam catapult and directly study the electromagnetic catapult that the United States began to put into use in the 21st century, because its requirements for the industrial base are relatively low, as for some of the principles and technical problems that are difficult to overcome, Tesla, the old monster, has been basically solved two years ago, China only needs to test and test on this basis, Hu Weidong estimates that it will only take ten years at most, and before that, you can consider using the sliding deck to make the transition

In addition, the difference between the carrier-based and land-based versions of jet aircraft is greater than that of piston aircraft, although the J-2 is a land-based jet fighter with excellent performance, but without special modifications, it cannot be directly on the ship. Hu Weidong handed over the job to Sukhoi, anyway, the Soviet Union does not have aircraft carriers now, and China is not in urgent need of jet carrier-based aircraft, so even if Sukhoi still misses the motherland, it doesn't matter much. However, it is better for China's historical grievances with the Soviet Union or Russia to be resolved as soon as possible, otherwise many of the so many foreign talents recruited at the beginning will not be able to use them with confidence, which really makes Hu Weidong quite uncomfortable

Among the many foreign experts, the most helpful to China's scientific and technological development is Goddard, the father of rocketry, and Tesla, the Frankenstein, but what makes Hu Weidong sad. Both died in 1946. Among them, although Goddard often consumed anti-cancer foods under the persuasion of Hu Weidong, he eventually died of throat cancer, only living more than one year longer than in history, but fortunately, Qian Lao, who has grown up now, is fully capable of taking over; Tesla lived three years longer than history, and finally died at the age of 90, it can only be said that birth, old age, sickness and death are inevitable, and in this extra three years, Tesla finally completed the unfinished masterpiece "Gravitational Dynamics" in history

Regarding the "Theory of Gravitational Dynamics", which was rumored to be miraculous in later generations, Hu Weidong had the opportunity to read part of the draft because of his close relationship with Tesla. Although I couldn't fully understand it because of the wrong major. But he was still able to find that although Tesla's theory was completely different from Einstein's relativity theory, it could still justify itself, and even derive the mass-energy equation. What makes Hu Weidong's forehead sweat even more is that the universality of Tesla's theory is even stronger than that of relativity. It's like unifying quantum theory with relativity. But here's the thing. His theories are all based on the acknowledgment of the existence of the "ether".

One theory has phenomena that cannot be explained, and another, while able to explain all known phenomena, is based on a concept that is only hypothesized and never proves to exist. This made Hu Weidong a little confused.

Hu Weidong naturally knows that the biggest possibility is that neither of the two theories is the absolute truth, but one must be chosen as the theoretical basis in scientific research and production practice, right? Students also have to make trade-offs when studying advanced physics, so which one should they choose?

Although he has a good relationship with Tesla, considering that the development of science and technology in the later world in history is based on the theory of relativity and quantum theory after all, Hu Weidong still prefers the relatively stable latter. But thinking that if Tesla's theory is closer to the truth, then doing so will make China miss the opportunity to lead a scientific and technological revolution, so in the end he feels that it is safer to walk on two legs, although China does not have such a huge reserve of scientific and technological talents for the time being, but with China's population, the potential is incomparable, and sooner or later there will be that spare power in the future

Therefore, in the end, after Hu Weidong won the support of Taizu, in the name of looking for "prodigies" across the country, every year he selected 100 teenagers with outstanding mathematical talents to be sent to the "juvenile class" of Zhongyuan University to receive special education, if Tesla's theory is finally confirmed, they will be the seeds of new physics, even if they are proved or cannot be confirmed for a long time, they are enough to become qualified electrical engineers, which is not a special waste. Far more scientists than this number are still taking the historically proven route, which is much safer.

The reason why many scientific research projects were concentrated in 1946 was certainly accidental, and the great importance attached by the party and the government should not be ignored. Since it is impossible for industry and economy to reach the ultra-high growth rate of the "First Five-Year Plan" period, the second five-year plan of the new China focuses on science and technology and education, and the enthusiasm of scientific research personnel is even higher, and the investment of human, financial and material resources is also more.

In fact, compared with the progress of materials and technology and the training of senior technicians, or the strengthening of the industrial base, the progress and growth of the team of scientists is much more rapid, even the few science and engineering students in the Republic of China period plus those thousands of young geniuses who grew up in advance under the education system that encourages skipping grades, after these five or six years of training and practice, there is already a considerable quality and quantity. Although there is still a big gap between them and the old powers, because Hu Weidong, a traverser, pointed out the correct research direction from the beginning, China's waste in scientific research is much smaller than that of other countries, and the efficiency of scientific research is naturally several times higher. Therefore, in the research of those key projects, except for those with higher requirements for the industrial base, China's scientific and technological advantages obtained by preemptive research have not only not shrunk in recent years, but are still slowly expanding.

Note 1: Because after the performance of the aircraft is improved, the requirements for the catapult will continue to increase accordingly, and the performance is not as good as the land-based aircraft jet carrier-based aircraft is meaningless, so if China wants to engage in steam catapults, it must reach the corresponding technical level of land-based jets in the same period to have practical value, unlike most technologies, if you only need to solve the problem, even if you make a product that has been available decades ago, it is considered a success. It is precisely because of this that in history, not to mention China, even superpowers such as the Soviet Union have not been able to overcome the problem of steam catapults, but this has also led to a somewhat hilarious inference that if the Soviet planes were worse, maybe they would have been able to make a steam catapult that meets the requirements (to be continued......
