Master of time and space

Dong Qiuhong took Yang Wentian and came to stand in front of a large group of data model conversion equipment. This group of equipment is particularly special compared to other devices. The device doesn't have many physical components, just a swivel chair that adjusts in height, a VR eye mask, and a pair of operating gloves, but it is equipped with a holographic projection platform with a large footprint.

"This is a multifunctional holographic imaging design instrument, which users can use to design product drawings and create and synthesize physical simulations." At this time, there happened to be an eight-year-old flat-headed boy in a leather jacket operating the equipment, and Dong Qiuhong signaled Yang Wentian to pay attention to watching, while explaining: "The ultimate goal of most scientific research projects is to invent and manufacture specific product entities, and designing relevant drawings is the most critical step, and specific drawings can be used for factory production."

"Inventing a new product today is not as difficult as it was a hundred years ago. With the help of this designer, people only need to synthesize the data of various basic components like building blocks to obtain drawings and even models of the new products they want. When Dong Qiuhong spoke, Yang Wentian saw the flat-headed boy sitting in the swivel chair, designing a drawing of a gun, the gun in the holographic projection screen has been built more than half, the base of the gun, the breech bolt, etc. have been simulated, but he has been switching between different artillery barrels, replacing several types, before deciding, and then selecting a few fine accessories, a holographic design of a ship-based large-caliber gun was presented in front of everyone. After some fine adjustments, the flat-headed boy was satisfied, made a note of the drawings, got out of the swivel chair, and ran to other study and research equipment.

"Now let you see the scientific research projects that my mentor has been working on." In order to inspire Yang Wentian to work hard, Dong Qiuhong sat on the control swivel chair of the holographic imaging design instrument and brought up a hologram.

"Oh, what a big spaceship!" As soon as the hologram was tuned out, it occupied the entire projection platform, and a huge ship model appeared in front of Yang Wentian's eyes, at a glance, it looked like an ancient Mengchong ship of the Huaxia Kingdom, and it was only after looking at Yang Wentian that he realized that this was the design drawing of a spaceship.

"This is a shuttle spacecraft designed to accommodate 10 Earth humans to explore deep space in and around the solar system." As soon as the design model of the spacecraft appeared, Dong Qiuhong's eyes flashed with a feverish light, and he whispered to Yang Wentian: "With the increasing population of human beings and the depletion of resources, human beings are more and more eager to go out of the earth and into the universe. Over the past hundred years, humans have launched many unmanned exploration spacecraft into the solar system and beyond. The farthest have reached space a light-year away. Speaking of this, Dong Qiuhong's tone changed from excited to slightly frustrated, "However, the space exploration of manned spacecraft is extremely limited, even Mars, the closest to the earth, has only landed twice, and even attempts to establish an observation base on the moon have repeatedly failed, and the exploration is still based on obtaining alien soil samples."

"In this way, once the manned spacecraft you study is successful, humanity will be able to move towards the universe." Yang Wentian did not understand Dong Qiuhong's mood deeply, his own peony suit had just turned on 50% of its combat effectiveness, and after having a vacuum propulsion system, if Yang Wentian wanted to fly away from the earth now, it could also be done.

"Yes, only by moving towards the universe, can human development have a future." Dong Qiuhong glanced at Yang Wentian and saw that Yang Wentian was not shocked by the holographic model of the spacecraft, so he put on a pair of operating gloves and reached out to operate on the projection platform. With his movements, the model of the spacecraft was disassembled one component by another, revealing layers of structure in the hull, and even component parts.

"It's not easy to complete the blueprint design of this spacecraft and put it into production." Such a huge project requires the unremitting efforts of one generation, two or even several generations. There is no shortage of geniuses in this world, but it is extremely lacking in multidisciplinary comprehensive geniuses, undoubtedly Dong Qiuhong is such a genius, and Yang Wentian also has such potential, and presiding over the design of the spacecraft requires such a genius to lead the center.

"Mentor, you said so much, is there any task entrusted to me?" Yang Wentian stood by with his back to watch Dong Qiuhong disassemble the drawing model of the spacecraft into parts.

"To avoid you wasting time, I'm going to put some pressure on you." Dong Qiuhong pulled out several parts marked with unfinished marks in the spacecraft design drawings from the spacecraft model and enlarged them slightly, "You choose one of these spacecraft component topics as your first research direction in the future."

"Please ask the mentor, which of these topics is more critical and important?" Yang Wen's dark eyes quickly scanned the information content displayed by the hologram. There are three parts taken out by Dong Qiuhong, one is the armored defense part of the spacecraft, one is the crew support module part of the spacecraft, and the other is the nano-engine part of the spacecraft's propulsion system.

"These three components are all critical, and if I have to say which one is more important, I personally think that the nano engine components are more important." Hearing Yang Wentian's inquiry, Dong Qiuhong closed his eyes slightly and thought for a while before reaching out and nodding on the holographic screen, further enlarging the engine parts in it.

"The universe is too vast, and the biggest obstacle that restricts human exploration of the universe is the speed of the aircraft." Dong Qiuhong said in a vivid tone: "Among the scientific phenomena known to mankind, the speed of light moving in the universe is the fastest, reaching 300,000 km/s. The first cosmic speed around the Earth is 7.9km/s, the second cosmic speed away from the Earth is 11.2km/s, and the third cosmic speed required to fly out of the solar system is 16.7km/s.

"Let's not talk about the speed of light, even if it is the speed of light, the aircraft made by the technology that we humans have mastered are far from reaching the speed of light." The vastness of the universe and the insignificance of human beings, the more knowledgeable scientists experience, the more profound they feel, "The fastest unmanned space exploration spacecraft built by human beings today only reaches a maximum speed of 60km/s."

"This spacecraft project, designed by the Ministry of Aviation of the Chinese Academy of Sciences, the maximum speed of the spacecraft is designed to be 100km/s, which is close to the fourth cosmic speed of 110km/s ~ 120km/s that can fly out of the galaxy." This is a matter of high national secrecy, Dong Qiuhong said with words like gold, "Today's engine parts production technology, most countries in the world use relatively perfect nanotechnology to manufacture.

"So what problems have you encountered in the design of the engine parts of this spaceship today?" Dong Qiuhong said a lot of words, Yang Wentian nodded understandingly, pointed to the image of the engine parts in front of him and asked with interest.

"It's hard to say, it's easy to say." Dong Qiuhong stared at Yang Wentian for several seconds, due to various reasons, Yang Wentian's appearance has attracted the attention of the high-level officials of many departments of Huaxia State, and Dong Qiuhong received the task personally issued by the president of the Central Academy of Sciences today to test Yang Wentian.

"The core of nanotechnology is to use as few nanomaterials as possible to build a variety of nanocircuits with specific functions, and then build nano elements from a large number of nanocircuits that can be connected in parallel or in series, and then a batch of nanocomponents to form a nanopart with a certain use, nanoparts and other parts to assemble into nano engine components, and finally synthesize multiple engine components into a complete spaceship nanoengine." After saying so much in one breath, Dong Qiuhong also had to swallow his saliva before continuing: "If you choose this engine topic as your research direction, you must first solve the problem of nanocircuits, first build a new nanoloop module with a smaller number of particles and more powerful functions, and other engine problems will be easily solved." At the end, Dong Qiuhong did not forget to flicker: "In fact, it is a fun building block game of playing with a few nanomaterials, which is quite simple for children."

"Answering questions and playing games have always been my strengths, so I will choose this nano engine subject." At this time, Yang Wentian was very pure and naïve, "But when I answer questions and play games, I need to eat candy." "
