On January 28, several fellows of the Royal Society visited the Baird Laboratory and inspected the Baird TV system demonstration. The report, together with the photo of the TV imaging taken by the photographer, was all published in It appeared in the Times that day.
Rutherford, president of the Royal Society, praised Baird's television system in a newspaper as a great invention.
Professor Bohr, who came to the UK from Denmark as a guest, also told reporters from The Times that Britain is a great country. From the Jenny machine to the steam engine, from generators to television systems, Britain’s development in science and technology has It has always been at the leading position in the world, and this lead has lasted for hundreds of years, and no one has been able to shake it so far.
Chen Muwu also acted as a boaster, touting Baird's great invention to reporters, saying that he also gained a lot of inspiration from the day's visit, which would be very helpful for his future scientific research.
Many Nobel Prize winners from various countries were invited to endorse it. It was difficult for Baird's invention of television not to cause a national sensation across the UK.
Chen Muwu didn't know whether several other monks, including the two above, praised the TV with only five frames per second so highly, from the bottom of their hearts or deliberately said it in front of reporters.
But everything he said was true. Baird's TV did give him two very important reminders.
After returning to Cambridge University, the part about electron microscopy can be put aside for a while, but the thing about insulating the environment around the motor must be implemented immediately. Human lives are at stake and there is no delay.
Whether Zhao Zhongyao was designing the drawings or Cockcroft was calculating the cost of building a generator, neither of them thought about insulation, so they only calculated the material price of the main part. .
After all, the generator model Chen Muwu made out of tin cans and silk ribbons could only provide "high voltage" of about a thousand volts, and the amount of charge was not much.
Even if a path is formed between this generator model and the human body, the current generated will basically be similar to the feeling of being electrocuted when taking off a sweater in winter, and it will definitely not be the numbing sensation when getting an electric shock.
But when the generator changed from a model to a real thing, the size of the spherical electrode increased to 80 centimeters, and the voltage reached the million-volt level, it was completely different.
Moreover, providing insulation for such a high-voltage generator must be expensive, and it is estimated that a large sum of money will be spent.
Chen Muwu won't feel bad about this extra expense at all. The more money he spends, the higher the price of finished generators manufactured in the future.
After learning from the capitalists at General Electric, he dared to ask for four thousand for a cost of twenty pounds.
If you add the cost of insulation, you can make a lot of money again.
It was also the same day that this "The Times" was published. After the Royal Society meeting and the TV demonstration, everyone at the University of Cambridge was finally returning to Cambridge from London.
Sitting on the return train, Chen Muwu could finally hide in the corner of the first-class carriage with peace of mind and be a little transparent without being noticed by others.
Whether it is Rutherford or his good student Bohr, these two are big figures who have absolute say in their respective laboratories or research institutes. They always say what they say and are rarely refuted by others, so over time they have become Became very talkative.
In addition, the two people, who have a deep love for each other as master and apprentice, have not seen each other for three years, and they have endless things to say to each other. They started talking from the moment they got in the car.
When Bohr was at the Institute of Theoretical Physics, he was majestic in front of the young talents in physics.
But when he got to Rutherford, his personality immediately became very docile, like a little sheep.
This is enough to show the great charm of Rutherford's personality, and also to see how much Bohr respected his teacher during his years of studying in England, and he has continued this habit to this day.
But Chen Muwu, who was quiet this time, still couldn't avoid the smoke in the carriage.
Perhaps it was because he studied under Rutherford, or perhaps because certain components in tobacco can refresh the mind and provide inspiration in physics. Bohr was also a big smoker.
Chen Muwu, who was now under the eaves, could only lower his head, but he told himself silently in his heart that after the Swedish school was built, the first thing he had to do was to put up no-smoking slogans in every corner of the campus, and to make smoking illegal. The fine is written into the school rules and motto.
Arriving at Cambridge University in the evening, Chen Muwu declined the dinner hosted by Rutherford at Trinity College in order to honor Bohr. The food there was not delicious anyway, and the rules were very cumbersome.
He got on his bicycle and hurried to another place in Cambridgeshire that Rutherford had specially found for him to build a particle accelerator.
This bicycle was modified for Eddington before, and Chen Muwu also made one himself.
He finally got rid of the three-year eleven road career and joined the Cambridge cycling army.
After decades of development, the layout of the Cavendish Laboratory has long been finalized.
There are conference rooms, libraries, lecture halls and a large open laboratory on the first floor. The second and third floors are independent experimental rooms, as well as the offices of teachers and professors.
Although the conclusion reached after calculation is that it is not necessary to build a giant spherical electrode with a diameter of nearly 20 meters and a height of 14 to 5 meters from the ground, as Chen Muwu imagined, to generate an electric potential of one million volts.
However, according to the design drawings provided by Zhao Zhongyao and Cockcroft, the height of the entire generator is still 2.5 meters.
This height must be far higher than the floor height of the old Cavendish Laboratory.
In the original time and space, in order to deal with the contradiction that the increasingly old laboratories could not meet the needs of various newer and more sophisticated instruments, Rutherford chose to be affiliated with the Royal Society in the last year of his term as president. The Maunder Foundation applied for and approved a grant, and selected a piece of land near Cambridge University to build a new Maunder Laboratory as a branch of the Cavendish Laboratory.
However, due to various factors, the Mond Laboratory had already begun construction in London many years in advance.
In the future, Kapitsa may still serve as the director of the Mond Laboratory, but he will just move his office from Cambridge to London.
But whether the Cavendish Laboratory can build a new branch has become unknown.
He had complained about Little Bragg before, saying that it was he who changed the research direction of this long-standing laboratory from radioactivity and nuclear physics to solid state physics after taking over the laboratory, which led to the gradual decline of the Cavendish Laboratory. It lost its status as the world's center for physical experiments and eventually declined.
But that was a last resort during Britain's wartime and postwar economic decline. If Little Prague hadn't done that, the Cavendish Laboratory might have declined faster.
But now it seems that the culprit is more like himself?
No, no, how is this possible!
To put it another way, if the accelerator project makes a lot of money for the Cavendish Laboratory, there seems to be no need for the teacher to use his power to go through the back door and get funding from the Royal Society to build a new laboratory independently, right?
That's right, I am not the culprit, but a great loyal minister!
Because it was far away from the Cavendish Laboratory, Rutherford's rule of finishing work on time at six o'clock was not strictly enforced in this new place prepared for the accelerator.
When Chen Muwu arrived, the room was still brightly lit.
But once inside, it became empty, except for a few sets of tables, chairs, and a movable blackboard, and not even a shadow of a motor could be seen.
Even though Cockcroft was an engineer by training, it would be absolutely wishful thinking for him and Zhao Zhongyao to make an accelerator together.
Whether it was a spherical metal electrode or a specific insulating glass pillar, neither of them could handle it.
But if you have the drawings and money, you only need to place an order with the factory that cooperates with Cavendish Laboratory. Only a fool will do it on his own.
Chen Muwu put forward his idea to them. While the customized parts were still in the factory and had not been shipped here, the room should be insulated immediately.
In an era without various polymer materials, today's mainstream insulation method is to use asphalt to bond mica sheets together.
The higher the number of bonded layers, the better the insulation.
Of course, you can also use asphalt and polystyrene with better insulation effect.
Only in 1926, polystyrene only existed in the laboratories of universities, research institutes and chemical companies, and there was no method or ability for commercial production - everyone was looking for this thing.
The BASF factory in Germany could not build a production line until the 1930s. Chen Muwu really couldn't wait.
He couldn't continue to roll polystyrene by hand like he had done before when he was producing plexiglass, and he was also too late in time.
And the products that have just been launched will be extremely expensive. In comparison, asphalt is cheap in large quantities.
Among insulating materials, the price of another kind of mica sheet is not low.
There are few mica mines in Europe, and those found on the market are basically shipped from African colonies or South America.
After telling them about the insulation, the other two people in the room also realized their negligence.
Fortunately, Chen Muwu thought of this, otherwise if someone were killed, they would probably be the first ones to taste the electric shock.
Oppenheimer was still in the United States and had not returned, so the procurement could only be left to Cockcroft.
To purchase these industrial supplies in large quantities in the UK, his identity as an engineer might make it more convenient than a lavish Jewish man like Oppenheimer.
In fact, it doesn't matter even if it is more expensive. Anyway, with six thousand pounds of funds in hand, Chen Muwu is not short of money at all.
After explaining all this, he "driven" Zhao Zhongyao and Cockcroft out of the room and asked them to go back and have a good rest. There was still a lot of work to be done in the next few days.
Chen Muwu also rode his bicycle again and returned to his room at Trinity College.
His valet at Trinity College brought him letters and telegrams that he had accumulated when he went to London for meetings in the past few days.
Maybe it’s because around the winter vacation, there is very little content about scientific exchanges and discussions in these letters and newspapers. Most of them are letters between Chinese people greeting each other on the eve of the Spring Festival.
There is also a letter sent by Yoshio Nishina from Leiden, the Netherlands.
In addition to the English delivery address and name, he also respectfully wrote the four characters "Chen Hancheng" with a calligraphy brush.
The Chinese name is followed by the title Ben, which is a sign of respect for the person, but it is not completely respectful.
However, didn’t I abolish the lunar calendar and switch to the Gregorian calendar as early as the Meiji period in order to leave Europe and join Asia and integrate with the West?
Why did Yoshio Nishina send him a Spring Festival greeting letter?
Is your face already so great?
After opening it, Chen Muwu found that the content in the letter was still the same:
First, he praised his various achievements in physics, saying he was the light of East Asia.
Then he said that he would always follow his example and not try to catch up, nor could he be left further behind.
When he saw the end of the letter, Chen Muwu didn't see the Spring Festival greetings, but he saw the true purpose hidden by Yoshio Nishina at the end.
This is not a congratulatory letter at all, but a recommendation letter!
No wonder he spent so much time praising himself and saying that some East Asians want to share the same hatred and develop together, and punish the European and American monsters in the future.
In the 1920s, Yoshio Nishina's rhetoric still had many supporters in China.
Many people believe that I defeated Russia in the Russian War, which proved that East Asians have the ability to defeat Europe.
The two peoples have the same culture and race, so they should unite to deal with Europe and the United States.
Even the former Prime Minister once had this view, but it was not necessarily true.
When his opponent was from the Feng faction, his opinions were very fierce.
When the opponents were replaced by Cao and Wu who were pro-British and American, they began to look forward to uniting with Japan to oppose Britain and the United States.
But this rhetoric can deceive others, but it cannot deceive Chen Muwu!
He read the letter to the end with the intention of having fun, and in the end he saw an even greater fun.
Yoshio Nishina recommended to him that there was a graduate of Tanglin Imperial University's Department of Physics who wanted to study in Europe.
I recommended the Cavendish Laboratory at the University of Cambridge to this graduate and informed Dr. Chen from the Light of East Asia who was also in this laboratory.
Yoshio Nishina asked Chen Muwu to open the door so that his compatriots could successfully enter Cambridge University and study superconductors with Dr. Chen.
Recommending one's compatriots is human nature and there is nothing ridiculous about it.
The key is that the person recommended by Nishina Yoshio is called Arakatsu Bunze.
During World War II, Ben's development of the atomic bomb was no later than the United States' Manhattan Project.
The most famous is the Nishiki project, which was jointly developed by the Japanese Army and the Institute of Physics and Chemistry to develop an atomic bomb. It is named after the first letter of the surname of academic leader Yoshio Nishina.
In addition to Project Ren, the Navy actually also has their atomic bomb research team.
Starting from Satsuma Domain and Choshu Domain, our navy and army began to dislike each other.
Naturally, it is impossible to participate in the development of a secret weapon like the atomic bomb.
The Army and the Institute of Physics and Chemistry have joined forces to develop Plan N, and our Navy has joined forces with Kyoto Imperial University to develop Plan "F".
The person in charge of Plan F was Arakatsu Bunce who was recommended to Chen Muwu by Yoshio Nishina.
Without knowing it, Army Red Deer recommended Navy Red Deer to him. This was the biggest fun Chen Muwu had seen recently.
