After the record was recorded, Alex took away the master belt.

However, he left behind several suppressed records for Rudy, and others also received one for memorial. In the end, only two or three of these first editions remained until the 21st century, one of which was in hand by Alex.

Someone once took out one for auction in 1970, but it ended up being sold at a sky-high price of one million US dollars. I have never heard of this kind of thing again, and the value of this record has become increasingly high, and it has reached a priceless level.

After these days of recording work, Alex realized that it was so inconvenient to live in an era without computers.

"It would be great if there was a computer! It would be much more convenient to record a record like that. Unfortunately, the computers in this era are still military supplies. More importantly, the computers are still the first generation, and the size is terrifying." Alex couldn't help but complain.

Wait! The computers that were just starting out were all electronic tube digital machines, so they didn’t use transistors yet!

Alex suddenly realized a big question, that is, whether to push it properly! Put the computer technology in this world a little in advance so that the era of popularization of computers will come soon. The question is, what should he do so so as not to attract the attention of the people in the Pentagon.

You should know that from electron tubes to transistors, the computing speed of computers has increased from thousands to tens of thousands per second, which has increased by more than 10 times. The most important thing is that the volume has been reduced a lot. This technology appears in the hands of an eight-year-old child, and it is chilling to think about it.

Alex thought for a long time and found that he didn't seem to know much about computer hardware knowledge. However, he did know that the transition from a computer to a transistor is very smooth, and it only takes a lot of time to replace the original tube with a transistor. The problem is that there are not so many types of transistors now, and it will take a few years before there are enough transistors to replace the tube.

The first transistor was manufactured in 1947, and in 1950, there were already bipolar transistors, and it would not be truly commercialized until 1953. The question now is not whether Alex can invent it, but whether he can get high-tech products such as transistors.

He smiled self-deprecatingly: "It's really a worry. Whether I can get the transistor is a problem."

After he figured out the problem, he put the problem aside, but he still planned to ask someone to ask. If he could get a transistor, he wouldn't mind pretending to be a genius inventor. There are so many strange things in this world, why should he tie his hands and feet? People should be free and easy when they live.

The person Alex looked for was a professor at the University of Chicago. Those professors still remember him fresh and they often contacted him. This time he happened to ask them to help. He was looking for the professor of mathematics, Sawyer, who had been teaching in Chicago for more than ten years.

Soon, Professor Sawyer had news. He was not an expert in this field, but some of his colleagues and friends knew about it. A friend happened to be in Bell Labs and knew about transistors well.

His friend was named William Shockley, who happened to be one of the three people who invented the transistor. When Shockley received a call from an old friend, he was studying bipolar transistors and he said everything he could say. The information about the transistor was no longer confidential. He had applied for a patent in 1947, which was a sensational news around the world.

"Sayer, why did you suddenly ask about these things? I remember you were not very interested in transistors before." Shockley asked strangely.

Sawyer said without any concealment: "Yes, I'm not interested yet. However, I have a kid who is very curious about your research, so ask me for it. By the way, do you have any information there? I want a copy, the more detailed it is. Of course, don't give me the secrets of your laboratory. If someone knows it, it will be difficult for you and I to be kind."

Shockley laughed and said, "You still want confidentiality, dream! No problem, I have some outdated things here, you can take them. By the way, who are you talking about?"

Sawyer then told Alix about it, and emphasized that he had tested an IQ of up to 220. He was very confident in Alex and had been in contact with Alex over the past few years. Other professors in the school did not think Alex had that high IQ, so this was the test method used by Sawyer to make a mistake.

He has been studying IQ testing issues, but after being denied, he was very annoyed. So he tried to find evidence from it and prove that his opinion was correct.

"Wow! The IQ of 220 is much higher than mine!" Shockley said jokingly. He was not very interested in the IQ test set.

However, people in this era are superstitious about these things, and many people are studying them. Sawyer is one of the experts. Mathematics professors are just his means of making a living, and IQ testing is his hobby.

"This child has such a high IQ, what's his name? Maybe I'll see him in the newspaper in the future."

"Sorry, I can't tell you his name. I have made an agreement with his parents to keep a secret for them."

"Okay, okay! You've been studying IQ tests all the time. Is this thing effective?"

"If you don't believe it, then I think IQ tests are useful anyway, which can help us find ways to improve human quality throughout the day. Through eugenics and eugenics, we can selectively retain people with high IQ and eliminate people with low IQ."

"Your remarks are dangerous, my friend! I remember the Nazis had done this."

IQ tests have been around for more than a hundred years. During World War II, the Germans believed in this method and believed that people could be divided into different levels by passing one test. They shouted that the Aryans were the best race!

Not only Germany, but also in the United States, there was an era of crazy superstitious IQ. The United States first launched a campaign of eugenics and eugenics in human history. More than 30 states in the United States have successively performed compulsory or secret sterilization surgery on the "non-eugenic groups" because the government believes that the IQ of these people is too low, and if they give birth to offspring, it will lower the IQ level of Americans.

There are also some states in the United States that laws stipulate that death row prisoners must undergo IQ tests. Once their IQ is less than 70, they will be regarded as mentally retarded and cannot be held responsible for their actions. The government cannot execute them.

Sawyer naturally knew the dark history, and he retorted: "Since you don't believe in the accuracy of IQ tests, what are you worried about?"

Shockley was speechless by his words. The two hung up the phone after chatting for a while. Sawyer ignored Shockley's jokes. He believed in his research and believed that Alex could eventually prove that his test was right.

The information was quickly delivered to Alex's hands. After just a casual look, he found that the bipolar transistor had not been invented until now. He only knew that it should have been invented in 1950, but he just didn't know who invented it.

As a science and engineering student, Alex certainly knows the principles and structure of bipolar transistors. This is the best thing about education in the Celestial Empire. No matter what kind of knowledge is useful or not, the school will try its best to put it into the students' minds.

The so-called bipolar transistor is actually made of two back-to-back PN structures, with current amplification. In this era, point-contact transistors have just been made, and have not yet developed into junction transistors. For manufacturing technology, the conditions are already ripe, but people have not thought of using PN structures to manufacture them.

Bipolar transistors have two basic structures: PNP type and NPN type. In these three-layer semiconductors, the middle layer is called the base region, and the outer two layers are called the transmitting region and the collecting region respectively. When a small amount of current is injected into the base region, a larger current will be formed between the transmitting region and the collecting region, which is the amplification effect of the transistor.

Alex hesitated for a moment, and he wrote down what he knew on a piece of paper and listed the structure and voltage parameters of various transistors casually. Of course, they were all explained in a conjecture-based tone.

Bipolar transistors are also called semiconductor diodes. They mainly rely on PN junction wages. Depending on the PN structure surface, there will be different diode types.

Point-contact diodes are formed by pressing a metal needle on a single wafer of germanium or silicon, and then using the current method. This type of diode is simple to construct, cheaper, and has a wide range of applications.

There are also key diodes, alloy diodes, diffusion diodes, tabletop diodes, plane diodes, etc., all of which were written on paper one by one by one by Alex in his spare time to sing. He just learned it for a while in his spare time and drew it well.

Some of them have not been written out, and those are diodes that use alloy technology, and the current technology is difficult to implement.

Alex wrote in great detail. This kind of thing was already a mess in later generations, but it was the most advanced thing in this era.

The most important thing is the theoretical parameters. With this part of the content, people familiar with transistor production can see it, which is a detailed design description drawing.

When Alex checked the information and wrote the bipolar transistor structure description, Sawyer was not idle either. He had been staring at Alex's movements and expressions, and he had also read the information given by Shockley, and he could not understand the things on it.

Unexpectedly, after Alex finished reading it, he pondered for a moment and then came to paper and pen, drawing and writing. The content above was a structural design diagram of the transistor. What he cared about was that the transistors also listed the parameters.

"How did he do it?" Sawyer remained calm on the surface, but was already shocked in his heart.

Science is not about singing and drawing, and you can produce results by patting your head. If anyone dares to do this, he will definitely be attacked by evil scientists. For example, Nikola Tesla, who claims to be able to do experiments in his brain, has his achievements that are obvious to all. Modern society is based on his invention of alternating current. However, he was rejected by the entire scientific community and even slandered as a liar. His fate in his later years was extremely desolate.

Ordinary people may not understand the legend of Nikola Tesla in the scientific community, but Sawyer's generation is very clear. People who do not understand Tesla will strongly deny Tesla's achievements, believing that this kind of invention and creation in their minds without experiments is a charlatan's words, and it is completely crazy nonsense.

Science is classified as superstitious about things that cannot be understood. For the aliens among scientists, they will even come up with religious guards to deal with witches and try every means to erase the other party. Shortly after Tesla's death, all his achievements were wiped out by these people, so that decades later, people could only understand him through some unofficial records.

Only those who know Tesla will be impressed by the other party's intelligence. For example, Mark Twain once had a deep friendship with Tesla, and he believed in Tesla's remarks. Mark Twain saw Tesla create a lightning ball and play with it in his hand. In his eyes, Tesla is full of mysterious colors, difficult to understand, but it is not a liar.

For this reason, he also wrote a novel based on Tesla. The name of this novel is "The Mysterious Stranger".

Sawyer was fortunate to meet with Tesla. In his judgment, Tesla is a very unique scientist. Others may not be able to understand Tesla and therefore attack Tesla's personality. Sawyer has no way to understand it, but he believes that Tesla may be a bit naive, but is definitely not a liar.

Since that's the case, Tesla must be a genius that ordinary people cannot understand. So what is the difference between them? IQ? Sawyer thought for a long time and finally devoted himself to the research of IQ tests, trying to find out the secrets.

Less than ten years after Tesla died, Sawyer saw another genius, how could he not be surprised?
