The size of the glass plate that receives the silver atom beam is about the size of a palm, and theoretically, after 18 hours of heating, magnetization, and high vacuum treatment, the silver atom beam should be able to precipitate a sufficient amount of silver layer pattern on the glass plate.

Professor Woodgate carefully dismantled the glass plate and placed it under a microscope for observation.

The Professor was like a statue, the rest of his body remained motionless except for the slight movement of his fingers.

"Professor, did you observe the pattern?"

"How so?"

The professor answered the question with a question, and Li Kangping and Allen felt that something was wrong.

"All I saw was glass." Professor Woodgate frowned and said, "Lee, Alan, you guys come and observe. ”

Li Kangping moved to the microscope, and he looked intently at the glass plate, trying to find the pattern of the silver layer.

Unfortunately, Li Kangping's observations, like those of the professor, have nothing but glass. The same is true of Allen's observations.

The equipment is fine, but the experimental results that everyone wants have not been obtained.

So what exactly is the new question?

"I've always stuck to the idea that we can't get satisfactory results from one or a few experiments." Professor Woodgate said, cheering up.

"The good news is that at least the new vacuum pump meets the experimental requirements." Li Kangping is optimistic to think on the bright side.

"Let's go back and get some sleep, and at three o'clock in the afternoon, Alan and I continue our experiments. Lee, you come to the vigil at eleven o'clock in the evening, can you do it? ”

"No problem, I can do it."

Li Kangping went back to the dormitory and fell asleep, and when he woke up, at half past two, he had a meal that could not be said to be breakfast, lunch or dinner, and then made a phone call in the public telephone room of the master's dormitory building.

"Hello, it's a pleasure to serve you." The voice of an operator came from the telephone receiver.

Li Kangping said into the microphone: "This is Columbia University, Mr. KP Lee, please help me pick up Mr. Charles Alfred Strauss on Long Island." ”

Operator: "Mr. Li, please wait. ”

After a while, another voice came from the phone: "Hello, Mr. Li, I'm Reina." ”

Reina was the French butler of Strauss House, and Li Kangping had met this butler at the last banquet, and he said, "Monsieur Reina, is Mr. Strauss here?" ”

Mr. Reina: "I'm sorry, please call me in ten minutes." ”

"Okay, thanks."

Ten minutes later, Li Kangping finally contacted Mr. Strauss.

"Lee, see you at five o'clock in the warehouse in East Harlem." Mr. Strauss gave a specific address and asked Li Kangping to go there at five o'clock.

At five o'clock, Li Kangping drove to Macy's warehouse in East Harlem.

The warehouse is stacked with all kinds of goods, and the workers order the goods, and it is a busy scene.

Li Kangping's 400 sets of mahjong are quietly piled up in a corner of the warehouse.

The customs clearance, transportation and warehousing of 400 mahjong pairs from Guangzhou, China, are all operated by Macy's staff, and Li Kangping's task is to collect money and see what his mahjong looks like.

"60 pairs of ivory mahjong, 340 pairs of bamboo mahjong, the quantity is correct, the quality is qualified, and the cooperation is pleasant." Mr. Strauss shook hands with Li Kangping, and he immediately introduced a tall and thin middle-aged man to Li Kangping: "This is Samuel, and Samuel will be in charge of the next thing." ”

Mr. Strauss, who was busy with business, left, and Li Kangping accepted Samuel's business card, a manager at Macy's.

Samuel said politely: "Mr. Li, we can remit $28,000 to Li's company in Guangzhou, or we can pay you cash." ”

"Give me cash, thank you."

"Okay."

After a few minutes of pleasant and harmonious conversation, $28,000 is nothing more than three stacks of $100 bills, put them in your pocket, and you're good to go.

Li Kangping didn't seem to have done anything too complicated about this transaction, he sent a telegram to his father, remitted $5,000 back, talked to Mr. Zhou and Mr. Strauss, and made a phone call, and $5,000 became $28,000.

With Li Kangping's character, of course, it is to celebrate.

But there was a follow-up experiment in the evening, so Li Kangping postponed the celebration plan.

Professor Woodgate asked Li Kangping to keep a vigil alone in the laboratory, which fully demonstrates the professor's trust in Li Kangping.

The new vacuum pump is still strong, and the rest of the equipment is normal, Li Kangping regularly checks the equipment, records process data, and spends the rest of the time reading German books against a German dictionary.

Xueba must have a plan to do things, why did Li Kangping work so hard to learn German, because he wanted to find an opportunity to go to Germany---- before Ximo came to power.

He lived in a complex and strange time---- the now-defunct Germanic Holy Roman Empire, an era that profoundly influenced every stage of his life and every aspect of his work...... The British suspected him, France ridiculed him, he committed suicide three times, and he lived to be in his seventies......"

Li Kangping is a language genius, he has been learning German for more than two months, and he can already read German history books in the dictionary.

Why is Germany a country of genius and belligerence?

The answer is not in the dark, nor in the morning morning at seven o'clock in the morning.

"Lee, I brought you a hot dog." Alan thoughtfully brought breakfast.

"Thank you." Li Kangping quickly got rid of the hot dog.

"Lee, there's nothing wrong with that, right?" Professor Woodgate asked.

Li Kangping said: "Everything is normal, we can observe the glass plate. ”

"It's hard work to keep a vigil alone, and Alan will rotate with you in about two weeks. Now, let's see the results this time. ”

The professor disassembles the glass plate and places it under a microscope.

"Like yesterday, there's nothing but glass." The professor was a little disappointed, but the result seemed to be within his expectations.

Li Kangping immediately made a suggestion: "Professor, Allen, I think we should stop the experiment immediately and re-check the equipment, the electric furnace, the silver atomic beam generator, the vacuum system, the electromagnet, the diaphragm, the grilled steel plate, the shape and size of the exit point, and even every screw, every line, and every buckle should be carefully checked. ”

Alan hugged his head and said, "Oh, it's going to take days!" No, no, it's going to take at least a week! ”

The professor lit a cigarette and remained silent, as if in deep thought.

The professor lit a second cigarette and remained silent.

"Professor, you have something to say." Alan was in a hurry.

"As I have said a long time ago, this experiment is extremely difficult, and if it is easy to do, then someone will do it in 1919 or 1920. The truth is that until now, in April 1921, we have not seen any reports of the results. This experiment is a test of our experimental skills, but also a test of our patience and confidence. ”

Professor Woodgate, who extinguished his cigarette, said: "Do it ten times in a row, and if you still can't see the silver pattern, then stop work and check it." ”
