Chapter 299 Lei Bushi's Self-esteem Xiaomi 1 already had everything ready, but people had other ideas about the hardware. Hardware matters are actually simple. If Lei Jun can ask Lu Shan to cooperate on the Extreme Browser, then he can also ask for cooperation on hardware? The performance of BanSi's memory and storage products is obvious to all, with a very high cost-performance ratio. They use new materials and there is still much room for improvement in the future. By that time, I don’t know how much it would cost to cooperate with Bansi again. It would be better to secure the long-term cooperation rights now before BanSi grows into a giant. "Let's talk about it later when there's a chance." Lei Jun rejected the following proposal in this way. If there is a chance in the future, it means there is no chance now. Naturally, his subordinates were very confused and tried to ask for the reason indirectly, but Lei Jun did not give a clear answer. This made his subordinates even more confused. BanSi is a domestic brand with excellent quality and is very popular. Wouldn't it be easier for a startup like Xiaomi to become a hit by cooperating with it?
Lei Jun has his own considerations. The first thing to consider is the constraints. At present, Xiao Mi has introduced Ji Yue in the browser, which is equivalent to giving up the bargaining power and accepting Lu Shan’s conditions in full. Although Lu Shan hasn't stated any conditions now, he will always bring up the idea of cooperation. Xiao Mi and Lu Shan are not qualified to discuss conditions at all. When the time comes, Lei Jun will have to agree to whatever Lu Shan says, otherwise it will be useless. If I continue to cooperate with Lu Shan on hardware, then I will be giving the right to speak on hardware to Lu Shan. For a mobile phone brand, the cooperation with browser and part of the hardware are all handed over to one person. It is too dependent on one person, and Lu Shan has too much control. In the future, who will have the final say in Xiaomi Company? If you have different ideas, who should you listen to? What Lei Jun wanted when he started his own business was absolute control. If he had to listen to others all the time and failed to realize his own ideas, Lei Jun would not have started his own business and would have continued to stay in his old company or stare at the cold and huge amount of money in his card for retirement. The second reason lies in a more complex emotion, which can be described as self-esteem. Lu Shan was just a young man in his early twenties, ridiculously young. Although he is a mathematician, he is just a newcomer in the computer field. And Lei Jun himself is also a young hero, different from ordinary people, who took on important responsibilities at a young age. So he always subconsciously compares himself with Lu Shan. If you can’t compare your achievements in mathematics, then compare your achievements in computers. If that doesn’t work, then compare your looks. If that doesn’t work, then compare the thickness of your hair… A man stays young until he dies. His desire to win never disappears, and it may even lead to strange projects. In a word, Lei Jun is not convinced by Lu Shan! The last reason is industry related.
Domestic mobile phone manufacturers basically buy accessories from foreign countries. Everyone is the same. No one should laugh at anyone else. After all, domestic accessories are really lousy, and there are not even decent mobile phone accessories manufacturers. People say that Compaq is good, but it has never seriously produced mobile phone hardware, right? In this case, it is not necessary to buy things related to silicon. Even if we want to buy it, we have to wait and see until Lushan has a related production line. Regarding Jiyue’s authorization, a contract still needs to be signed. Before that, we will do an internal test to see the effect. So Lei Bushi boarded the plane to Jiangzhou, and went directly to Jiyue Company after landing. Lu Shan also showed up at Jiyue on time. Looking at Lei Bushi, Lu Shan really admired him in his heart. Putting aside the messy comments made in later generations, at least this guy was really passionate. As for the many shady operations behind Xiao Mi, whether they were carried out after the funds came in, Lei Jun could not completely control it. Lu Shan did not know and did not comment. At the very least, Lei Jun is a real expert in technology, and his technical skills are also quite good for Ji Yue and Ze Meng. Thinking of this, Lu Shan himself found it funny. Everyone was waiting for guidance from an expert, but he actually wanted to give guidance to an expert and let Lei Jun write code for him. Putting aside these messy thoughts, Lu Shan had a good chat with Lei Jun, and the cooperation contract for Jiyue Browser was also signed. Lu Shan still did not make Lei Bushi pay any price, but reserved the right to terminate the cooperation at any time to prevent Xiao Mi from messing around. At this time, Zheng Kaige was a little conflicted. He thought about the hardware issue, but his boss didn't mention it, and neither did Lei Jun. It seemed inappropriate to bring it up at his level. When he found an opportunity, Zheng Kaige asked the question tactfully, but Lei Jun also tactfully refused. Zheng Kaige is no longer the young man he was back then (a year ago), and he understood Lei Jun’s refusal. Unable to figure it out, he reported the matter to Lu Shan. Lu Shan understood it after thinking about it for a moment, and just laughed it off, not taking it seriously at all. Lei Jun is right not to put all his eggs in one basket. I would do the same if I were in his shoes. But what should we do if there is only one basket in the market in the future? If you don’t put it in my, Lu Shan’s, basket, how can other people’s broken baskets hold it? Lu Shan cooperated with Lei Bushi mainly to see what else this smart man could accomplish in this life. This is called mutual appreciation. So this negotiation went very smoothly. Lei Jun was worried that Lu Shan might ask some harsh questions. In the end, Lu Shan didn't mention any of them. After sending Lei Jun away, Lu Shan returned to Singularity Labs and began to work on graphene batteries. Who wouldn't be excited about a battery that can be charged by relying on the properties of microscopic physical materials? The research ideas are already very clear and have a certain theoretical reserve. "The crystal structure of graphene is a single-atomic-layer two-dimensional crystal, formed by carbon atoms connected by SP2 hybridization and regularly arranged in a honeycomb lattice structure unit. In addition to being connected to three other carbon atoms by σ bonds, each carbon atom's remaining π electrons form delocalized large π bonds with the π electrons of other carbon atoms. Electrons can move freely in this area, giving graphene excellent electrical conductivity." "With this feature, we can build models to observe the movement characteristics of electrons and collect data." At this time, Mary was a little confused: "But when electrons pass through the graphene ribbon, will they have no mass?"
"Chemical bonds are localized, that is, chemical bonds are only between two atoms or a few atoms." "The large π bonds in graphene determine that its electrons can move freely within the graphene. The energy band diagram shows two linear straight lines. The effective mass is proportional to the second derivative of the energy band... In other words, they actually pass through the graphene range in the form of waves." "I see. Wave-particle duality?" "It's similar to this statement. But we still need to verify this step again. I can't fully believe what other laboratories say." "So what structure form will our battery take?" Mary asked the most realistic question. As we all know, graphene is only one carbon atom thick. The carbon atoms are arranged in a planar hexagonal structure and extended into a planar structure in a honeycomb shape. This structure not only gives graphene excellent mechanical, electrical and optical properties, but also enables it to construct fullerenes (C60), graphene quantum dots, carbon nanotubes, nanoribbons, multi-walled carbon nanotubes and nanohorns. This is where the problem arises. What the structure is does not entirely depend on what Lu Shan thinks, but on the stage of the graphene extraction process. Graphene can be roughly divided into single-layer, double-layer and few-layer graphene according to the number of layers. The first two categories have similar electronic spectra, both are zero-bandgap semiconductors (semimetals with valence band and conduction band at one point), with two types of carriers: holes and electrons. So how should multilayer graphene be applied? Are single-layer graphene simply stacked or rolled up to increase performance? The disadvantages of superposition are visible to the naked eye. It is unstable. Just imagine putting those very slippery and thin iron sheets together. A little force will cause these iron sheets to separate. If it is rolled or folded, you have to consider how big the individual boards are. Moreover, it is not necessarily the case that the effect will be stronger just because it is rolled up. We really need to do experiments to evaluate it. The difficulty lies in production and preparation. This link is based on basic theory, but it involves the arrangement of graphene crystal structure and the force and dispersion problems when electrons shuttle. These all require the construction of mathematical models and calculations on supercomputers. So Poincare and Turing got involved and actively put forward their own opinions. Poincare knew a lot about physics, and Turing had absolute say in computers. The four of them continued to evolve their ideas into feasible models. When the IQ reaches this level, the brain is like a computer. After calculations by four super brains, the feasibility is determined and then put into the supercomputer for calculation. It’s not that Lu Shan doesn’t have the money to buy production equipment for experiments, but that the place is too small to accommodate them. So everyone had to decide to run it on the supercomputer first. Otherwise, they would have to order equipment from outside, and it would take time to produce it, and the key was that it might not even work. Lu Shan has two supercomputers, one in the virtual laboratory, which is used by Turing. Its current task is to optimize Cocoa Assistant and prepare to design an operating system. Another set of running coco assistants in the real world. This time, the supercomputer in the Singularity Laboratory has a new task, and Lu Shan wants to try something new. "You mean, this time we are not only simulating the working model of graphene, but also simulating the normal production process?" Mary frowned. "Can the production process be simulated? Will the deviation be too big?" Turing spoke first at this time: "As long as there are enough conditions and variables, the model calculation process is almost the same as the actual one. The previous topological semimetal semiconductor material was run on a computer with a mathematical model, and the calculation and experimental process were all calculated." “The production process is actually a more complex and specific experimental process.” The reason is clear. There are many environmental conditions in production. How detailed the calculation model must be and how powerful the computer performance must be to take so many into consideration? If the computer cannot keep up, it will definitely crash.
Mary was still a little skeptical. She had experienced the power of computers and believed that they could calculate mathematical problems, but this already involved practical issues. Unless the computer was directly connected to reality and could sense the temperature, air, moisture, voltage and so on of reality. Turing patiently explained: "The reason why computers can simulate the experimental process and find problems in it is because the logic has not changed. Computers don’t understand the feelings brought by these environments in reality, but they understand logic. Mr. Lu Shan’s computer model building logic is no longer the same as in the past. After the Riemann hypothesis has been achieved, we can better let computers understand the logic in reality. For example, the combustion of oxygen and hydrogen produces water. This is logic and the truth of all things in the universe. We only need to input the many parameters that constitute the logic into the model to get the process. Of course, we use the building blocks approach to verify this.” “Building with blocks?” Mary was puzzled. "It means to make the small logics work first, and then stack the small logics together to form a larger logic. After the larger logic works, they are pieced together to form the large logic. This way, the logic can be guaranteed to be smooth at all times." Poincare also answered his fellow villager at this time. To be honest, this is not shameful. When I first heard Turing say this, I also thought Turing was talking nonsense. Facts have proved that Turing's computer logic is indeed unique. There are definitely people who are better than him in mathematics, but no one can beat him in computer logic. Mary is also smart: "In this case, the workload of calculation is very considerable. Do we need to build so many small logics one by one?" "No, all the repetitive work is done by Coco Assistant. We just need to check it." Speaking of this, Poincare looked relieved. All current research requires building models. If I have to build them one by one, I’ll want to die. Fortunately, Cocoa Assistant has the ability to learn. It has learned all the logic. No matter what reaction model you want, it will automatically adjust and build it without having to be taught again. It’s still the same analogy. Once you tell Coco Assistant about the reactions of different elements, Coco will automatically build the model when it sees the molecular formula, and it will react automatically. When iron reacts with air, iron oxide is produced at first. If you leave it alone, Coco Assistant will continue to react and give you iron oxide. That's pretty much the principle. So you really have to keep an eye on the time, at least say hello to Coco Assistant, and fix the results when the reaction reaches a certain level and the product appears. It does not have the ability to perform segmented operations yet, so you still have to watch it. In time, Coco Assistant will surely be that smart. "Okay." Mary nodded, her heart full of anticipation. So the most complicated prerequisite work began, which was to input the basic experimental data given by Mary. There were too many variables, and Turing spent a whole day typing but still couldn't get it right. Turing, whose hands were numb from typing, turned around to ask Poincare to take over, but found Poincare eating a watermelon. He became furious. (End of this chapter)
