In mid-July, Albert Einstein arrived from the Middle East with a research team.
Laser and light conduction and electronic computer research work was added.
However, Zhang Chun said that it is best to study laser ranging and navigation technology first, and at the same time study multi-band remote sensing and solar power generation, which are all very useful technologies.
Zhang Chun Induction Institute and Albert Einstein said: "What is our most advanced technology?
It's rockets, and if we increase the speed of rockets to the point where we can break away from the gravitational pull of the Earth, we can send things into space.
If we can build a device that can use multi-band measurements, plus solar panels.
What do you think I can do?
Can you monitor the clouds in the sky and predict the weather?
Can you measure the terrain, right?
Let's be able to measure all kinds of galaxies.
Maybe you will be able to reveal all the phenomena of the universe. ” Albert Einstein nodded wildly.
Wait for the people in the institute to leave.
Zhang Chuncai said to Einstein: "That old love, there is one thing you must remember, they actually want to do a very dangerous thing.
They want to control the nuclear transformation artificially, or they want to build a big nuclear bomb.
Think about it, what would happen if they could get the nuclear transformation past the tipping point?
” Einstein blinked: "Can they do it?"
” Zhang Chun smiled: "They were taken into the ditch by me, do you know what it means to be brought into the ditch?"
” Einstein nodded: "It's that they will fall." ” "That's right, the Xinmin Research Institute is very particular about the environment, and according to your theory, it can be deduced not only nuclear fission, but also nuclear fusion.
Isotopes of hydrogen are used to create nuclear fusion.
It is a relatively clean energy source, an inexhaustible source of energy.
However, nuclear fusion is very difficult and cannot be successful in a short period of time. ” Einstein thought for a moment and said, "Indeed."
Nuclear fission is much simpler, they just need to bombard it with neutrons, and you're doing this experiment. ” "Yes, but what is produced by nuclear fission is very radioactive and difficult to deal with.
The nuclear bomb is a devil, let's not touch it, at least not in the first place.
Can you imagine the bombing of a city with a nuclear bomb?
It will cause more than 100,000 deaths in an instant.
It doesn't matter if it's a woman or a child.
You have to find a way to delay their research, you don't underestimate their stubbornness and ability, they won't give up if they don't research it.
However, many of the results of their peripheral research can be applied to society.
For the benefit of society.
For example, lasers, lasers can operate on people, the wound will be small, and there will be less bleeding.
Lasers are capable of distance measurement.
Scan.
A lot can be done through the conversion of electronic signals and visual signals.
Anyway, you're going to use this to interfere with their research. ” Albert Einstein laughed: "You're cunning, but one thing you forgot is that these technologies will also speed up their nuclear research, such as computer technology that will make complex calculations simple."
This will save them a lot of time.
So you can't avoid it. ” Zhang Chun sighed: "Anyway, I don't plan to be the first to study it, I don't want to be a sinner of mankind." ” In August, the Yangtze River Bridge was closed.
It's just that Zhan Tianyou still couldn't see the connection between the Jinghan Railway and the Guangdong-Hanzhou Railway, and he suddenly suffered a stroke at the bridge deck construction site of the Yangtze River Bridge.
After rescue failed, he died in Wuhan Xinmin Hospital.
Ships on the Yangtze River and trains at the Wuhan railway station mourn with their whistles.
Zhang Chun, who was giving a lecture at Wuhan University, took the students to pay a moment of silence.
Then he said, "Don't forget to carry on the legacy of the deceased." ” Zhan Tianyou was cremated in accordance with the suicide note.
His family was scattered in the Yangtze River, and he wanted to watch the train roar across the Yangtze River.
Cremation is a plan proposed by the Ministry of Agriculture in order not to deplete the land reserve.
Zhan Tianyou, Liang Qichao, Cai Yuanpei and other older generations have signed to support.
The Kuomintang's purging of the party led to the complete collapse of the grassroots party organizations, but the number of party members did not decrease, because the workers and peasants killed and expelled the party members.

But some landlords, gentry, and merchants were raiding into the party.
Tens of thousands of party members who did not pass the organizational review entered the KMT.
The original slogan of Chiang Kai-shek to crack down on the reactionaries at the same time as the purging of the party came to naught.
This time, although Chiang Kai-shek re-elected the party chairman and unified the opinions of the party, he completely lost the countryside and the factories and became a bourgeois party through and through.
In October, because the ** staff surging in Hailufeng, which was too far away from Hunan and was surrounded by enemy troops, he took more than 800 core members to Jiujiang on the Saas cruise ship.
However, Cai Tingkai still attacked Fujian on the grounds that the National Revolutionary Army was counterinsurgent, and Sun Chuanfang was afraid that the Wuhan government, which was reorganizing the army, would attack Anhui, so he concentrated his main forces in Jiangbei and was unable to counterattack.
Wealthy merchants in Jiangsu and Zhejiang, who supported Chiang Kai-shek's hardliners, turned to the Nanjing government, which frightened them and even the Jin merchants in Shanxi.
Sun Chuanfang's attitude made them lose hope.
Chiang Kai-shek decisively launched the Second Northern Expedition, attacking Fujian and Jiangxi.
Sun Chuanfang stabilized his position on the front line of Shangrao and Wenzhou and launched a counterattack.
A confrontation was formed with Chiang Kai-shek.
The negotiations between H.E.
Arnold and Cai Wuji changed again and again, and originally Cai Wuji only wanted an underwater exploration submarine for scientific research, after all, the Wuhan shipyard was used to dismantle it.
But after Germany was restricted in military development, the Hardway shipyard in Kiel was in the most difficult period.
The Hardway Shipyard negotiated the possibility of conmodifying an unfinished UC-type submarine and selling it to China as an underwater research submarine.
Cai Wuji also told others that this submarine was too big, and Xinmin Academy mainly conducted scientific research in inland lakes, so it was not needed.
The Hardway Shipyard said that it could design a small submarine that could carry personnel for deep diving, but there was no engine, only a battery, which was propelled by electricity and charged by a submarine.
Cai Wuji agreed.
When the conflict between the Kuomintang and Sun Chuanfang broke out, Cai Wuji said that the U-boat was too big to sail in the Yangtze River, and it was unsafe to sail in the Yangtze River, and it needed to be delivered as soon as possible.
Because of its small size, small submarines can be brought by merchant ships.
Otherwise, as soon as the battle starts, the contract will have to be nullified.
H.E.
Arnold also felt the atmosphere of the great war in Hong Kong and was very anxious.
However, the Hardway Shipyard still finished the UC-type submarine one by one, and they said that the quality and reputation were gone, and the Hardway Shipyard had no need to exist, and they wanted to maintain the last glory of Germany.
In fact, in 1928, the situation in Germany had improved, but the rigid and grudgeful character of the Germans gave Zhang Chun a profound experience, and it is no wonder that there was World War II.
In November, a submarine that had been out of order for almost a decade secretly drove into the Wuhan shipyard.
It also carried a crew of 16 people, which was used to train the researchers who operated the submarine.
Li Zhilong was overjoyed, and while inviting these crew members to give lectures at the Naval Engineering College, he sent technicians to measure the hull structure.
As for the engine inside, the machine plant is not yet in sight.
However, the Germans did not know this, and they took the power plant to a certain extent, believing that this would lead to a subsequent maintenance contract.
The big one of this submarine belongs to the navy, and the small one belongs to the Xinmin Academy.
The Germans also knew that China was not only selling this submarine for scientific research, so they also acquiesced.
The only flaw was that the submarine was not equipped with sonar.
However, the Wuhan shipyard found passive sonar when salvaging the fleet of the four countries.
And on this basis, the study of passive and active sonar was carried out.
The gyroscope and inertial positioning measurement and calculation developed by Yanmen Precision Instrument Factory have formed a complete set of methods, but it is a little troublesome for technicians to pull the slide rule.
As for small submarines, they are powered entirely by electricity, requiring small size, flexible operation, high safety, and personnel being able to go out of the cabin for activities, which requires complete shallow water equipment.
Although this set of things must be completed in accordance with the contract's one-year timeframe, this is the result of repeated concessions.
After the submarine drove back to the shipyard, it entered a special dock.
Confidentiality measures have also been taken to the outside world.
Researchers at the Naval Engineering College used drawings and their own measurements to carry out the checks.
It was found that the Germans, though masked, were frighteningly accurate in their dimensions, and perhaps attached great importance to the relationship of the contract, except for the removal of the power system.
Other instructions and drawings are almost identical to the actual dimensions.
So the researchers believe that the structure and submarine principles on the drawings and instructions are credible.
It's really not good, and it can be tested if it is made.

Based on the tradition of Xinmin University, even a building model is analyzed and tested mechanically and structurally.
They tried to do a comprehensive calculation of the hull, but they still took it to the computer of the Institute of Physics.
At this time, the computers of the Institute of Physics were just standard "calculators" that could only calculate.
And the designers have already begun to design their own submarines.
Because you can't really throw money at the Germans.
