In this way, Kerry slowly adjusted, and began to pay attention to Arecivo's tedious ionospheric research, and Lipper and his cooperation were still close, seeing Kerry's interest in the ionosphere, Lipper spent significantly more time in the observation room.

Fast forward to 1973, and in the summer of that year, truckloads of supplies were brought from the naval base, and the engineers unloaded pieces of aluminum plates from the trucks, and removed all the metal mesh of the Arecivo telescope, and they riveted millions of aluminum plates one by one on the mirror surface, and when the sun came out, the people with shiny aluminum plates could not open their eyes, and the seabirds flew past the focus and fled in horror.

Emily doesn't understand why, so she asks Kerry, who only knows that aluminum plates reflect shorter wavelengths, but can't guess why. While they were guessing, a vehicle was sent from the naval base to pick up Kerry and Lipper.

It was Anderson who met them, I hadn't seen him for a few years, Anderson was already full of gray hair, and there was a young man in the office, "This is Mr. Clifford," Anderson introduced the young man after a cold talk with them, "He was sent by NASA, don't look at his youth, he was the chief engineer of Westinghouse Electric before he came to NASA." ”

"General, you summoned us after so many years, won't it be just for us to meet this new friend?" Lipper ignored Clifford's outstretched hand and remained lukewarm to Anderson.

"It seems that you haven't forgiven me yet, I really envy your free days in Arecivo, you don't know how I survived the past few years in the naval communication station, now the Soviets are overwhelmed in space, in the ocean, and on land, and the brainwave project has been going on for ten years without progress, which has cheapened IBM, their supercomputer is getting faster and faster, but my pressure is increasing day by day, you look at my gray hair."

Anderson pointed to his head, "Then again, I still have to thank the Soviets, without them, the Admiralty wouldn't have been allocating funds to Arecivo." As you can see, the radar is all equipped with aluminum plates, and we are going to search for brain waves in the centimeter band. ”

Kerry and Lipper finally understood why Arecivo had embarked on such a major project. "However, now that the country has reached an anti-war upsurge, it is more difficult to increase military spending than to ascend to the sky. I want to thank you for that, because without the two of you in Arecivo, the MPs really wouldn't have believed that this was a scientific project. ”

Anderson laughed inexplicably, "Now we need you to complete a project that will make the world more visible, so that our super radar is more like a scientific research project, for peace rather than war." Clifford, it's better for you to tell these two seniors. ”

Clifford stood up, it turned out that the Admiralty had been difficult to ride a tiger, and it had cost countless dollars in ten years, so it had to propose a supplementary budget to the Department of Defense to expand the search range to the centimeter level.

In order to pass Congress, the Arecivo project was packaged as an astronomical project to find extraterrestrial civilizations, and the telescope was given the task of receiving radio waves of intelligent life in the universe and handing it over to the computers of the Navy's communications station for analysis in the hope of finding extraterrestrial signals.

Clifford came to Puerto Rico to plan a propaganda project, and after the renovation was completed, a beam of electromagnetic waves carrying signals of human civilization would be sent into space through the Arecivo super radar, which was a plan that Nixon himself had finalized.

He had already visited China the year before, in 1973 he had decided to stop interfering in Vietnam, Nixon needed a striking symbol to assert his political image, and finally, he fell in love with the Aresivo project, which would both establish his image and increase his legitimacy against the Soviet Union.

"So that's it, ugly politician!" Lipper cursed indignantly.

Anderson knocked on the table, "Cherish the opportunity of Arecivo, either close the door or return to the naval base!" Kerry and Lipper had no choice but to accept Anderson's request and return to Arecivo unconditionally.

Clifford came to Arecivo, and his only mission was to wait for the super radar to be completed, press the button, launch the radio waves of human civilization information into space, and then report to the president.

Clifford showed Kerry the information of the radio waves he was going to emit, from top to bottom, there were seven sequences, the first group was the ten numbers from 1 to 10 expressed in binary, according to Clifford, the preferred communication language in the universe was mathematics, the second group was the serial number of the chemical elements contained in human DNA, the third group was the chemical formula of nucleotide, the fourth group was the double helix shape of DNA, the fifth group was the shape of a person, the sixth group was the composition of the solar system, and the seventh group was the aperture and wavelength of Arecivo's telescope.

After reading this information, Lipper laughed, "You guys are ridiculous, that's right, intelligent beings must use mathematics to communicate with each other, but the form of life in the universe is not just proteins, you see electromagnetic waves, we humans can't see or touch, maybe it's a form of life." ”

Clifford's face twitched in embarrassment: "I'm just in charge of the execution, and this is the collective wisdom of NASA's scientists that is finally decided by the president." ”

"I heard Anderson say that you used to be the chief scientist of Westinghouse, and we have received a strange signal here before, maybe it is alien, you can take a look." Clifford listened to Kerry's words and immediately became interested, he and Kerry entered the observation room, Lipper turned on the oscilloscope's 1965 storage signal, Clifford glanced at it and said, "Where are you from?" ”

"Telescope in Arecivo, early morning August 3, 1965." Kerry replied.

"It's not a signal from aliens, it's a signal from humanity itself." Clifford whispered, his voice not loud, but startling Kerry and Liverpool.

Clifford recounted the story that Frank told to Dr. Tadashi Ito, and seeing that Kerry and Lipper listened attentively, Clifford continued: "Actually, everyone said that Edison didn't get the data, which is true, but the data was still sent out. The alternator that Edison bought on the black market was produced by our Westinghouse company, when Edison asked someone to buy such a high-power alternator on the black market, it attracted the attention of Westinghouse, because Edison insisted on direct current technology, the company lacked alternating current experts, when the Ministry of Justice asked Edison to send someone to the prison to install and debug the alternator, Edison panicked, so he had to spend a lot of money to hire engineers from black market agents, and Westinghouse just sent its own engineers to the prison, When they discovered Edison's secret, they secretly installed a line to introduce the capillary electrometer signal into the telephone line. The warden thinks he's destroyed the secret, but he doesn't know that the Westinghouse engineers have already gotten the secret of the electric chair. ”

"And then," Kerry asked with Lipper.

"Westinghouse doesn't take this seriously, but there is an engineer in it, Cesazhong? Lombso was inspired by this to invent the pulse polygraph instrument, and Westinghouse data was sealed for decades until the end of World War II. Based on this, Reed invented the Reed multispectral scanner, which can measure the bioelectric changes of pulse, breathing, and muscles in all directions, and use it for polygraph. The persecution of Communism during the Truman era increased funding for research in this area, and Westinghouse was hired to do such research. Later, I joined this project, by chance, I wanted to try the stimulation of the Tesla high-voltage coil on the human body, when I connected the measuring instrument, stood on the side of the Tesla high-voltage coil and turned on the electricity, something strange happened, I actually saw the same pulse signal on the ECG and the same pulse signal you just played on the oscilloscope, I repeated the experiment, and realized that this signal is hidden between the sharp wave frequencies of the heart, which may be excited by the special environment of the Tesla coil. But before I could go any further, I left Westinghouse. ”

"Why doesn't the government have this information? Nearly a decade after Anderson's discovery in 1965, he still knows nothing. Kerry asked.

"You know why I left this project, my father was assassinated by McCarthy, why should I hand over the research results, they were obviously suspicious of me, and quickly ruled me out." Clifford looked agitated.

"Why are you telling us?" Lipper was very suspicious that Clifford had been sent by Anderson to trick them.

"I'm the chief engineer of Westinghouse, and I was the first to discover this phenomenon, but there is no condition to solve this secret, only you have received this pulse wave, and only the supercomputer in the naval communication station has the conditions to decipher this pulse signal."

"It's a pity that we've been ruled out as well." Kerry sighed, and just as they were talking, Assanzi walked in with a sad expression, "Dad, tell you bad news, Mom doesn't know yet, I'm going to go to the battlefield in Vietnam." ”

"What!" Kerry couldn't believe his ears, "Didn't President Nixon announce the cessation of interfering in Vietnam?" ”

"This is the last group of soldiers, said to replace the front." Assanzi was weak, "Dad, I don't want to go." ”

"You're only eighteen years old, you've just graduated from high school, and you can't imagine that we can't escape so far from the United States." Kerry was sad for a while, he really regretted it, if he still stayed at the naval communication station, maybe he could still try to get Kerry to escape military service, but now, who can he beg for.

"Eighty percent of the hell is Anderson's fuck, this bastard." Lipper cursed, Kerry couldn't hear what they were saying, and he was wondering what to say to Emily.

When the Arecivo telescope was being renovated, after several years of frenzy in China across the world, the Red Guards had already been sent into the vast countryside by the movement to go to the mountains and go to the countryside, and the **** escape shocked the whole country.

Liu Weiping, who has grown into a young man, is indifferent to these, when his classmates are keen on the national series, he locks himself in a house in the countryside of Xinyang, and reads the books left to him by Lin Sen all day long, he is the most educated person in the village, because of his brother who died on the Korean battlefield, his red and dedicated family composition saves him from attack, and reading the "People's Daily" to the people of the village is his main job every day.

On the morning of August 26, the members of the People's Commune had just finished pulling grass from the field, and everyone sat on the threshing floor and began to listen to Liu Weiping read the newspaper again, "Peking University, Beijing Cable Power Plant, the Ministry of Combustion and Chemical Industry and other units have jointly tackled key problems, and China's first integrated circuit electronic computer with one million operations per second has been successfully trial-produced!" ”

The members didn't know what he was reading, and Liu Weiping didn't know what an integrated circuit electronic computer was, so he decided to figure it out so he could explain it to the members. At this time, Liu Weiping did not know that this would be a decision that would change his life.
