Pang Xuelin is interested in neutrino detectors, to be exact, he is interested in neutrinos.

The discovery of neutrinos is related to the famous β decay energy theft case in history.

In the twenties of the twentieth century, physicists discovered that neutrons lose energy when they decay into protons and electrons (β decay).

Nils Bohr, the founder of the Copenhagen School at that time, believed that the loss of energy during the decay of β indicates the failure of the law of conservation of energy.

In the spring of 1931, the International Conference on Nuclear Physics was held in Rome, bringing together the world's top nuclear physicists, including Heisenberg, Pauli, Marie Curie, etc.

Pauli proposed at the meeting that the law of conservation of energy in β decay process is still correct, and the reason for the energy loss is because neutrons, as a mass neutral particle, become protons, electrons, and a neutral particle with a small mass during decay, and it is this small mass particle that carries the energy away.

The energy-stealing "thief" predicted by Pauli is the neutrino.

But at that time, there were no experiments in the physics community that could prove the existence of neutrinos.

It was not until 1956 that American physicists such as Cowan and Rine directly detected neutrinos through experiments for the first time.

For the first time, neutrinos were revealed to the world.

Neutrino is a kind of lepton, is one of the most basic particles in nature, neutrino is not charged, the mass is extremely small, the spin is 1/2, the mass is very light (some are less than one millionth of an electron), moving at close to the speed of light, the interaction with other matter is very weak, almost does not interact with other matter, and is widely present in nature.

It can freely pass through human bodies, walls, mountains, and even entire planets, making it difficult to capture and detect, so it is called the "invisible man" in the universe.

Nuclear reactions involving weak interactions in the Sun's interior produce 10 neutrinos to the power of 38 per second, which flow unimpeded from the Sun to space. Every second, 1,000 trillion neutrinos from the Sun pass through everyone's body, even at night, when the Sun is on the other side of the Earth.

In the Standard Model proposed later, there are 12 kinds of most basic particles that make up the material world, including 6 kinds of quarks (upper, lower, odd, can, bottom, and quark top, each quark has three colors, and the antiquark of the aforementioned quark), 3 charged leptons (electron, μ, and τ), and 3 neutrinos (electron neutrino, μ neutrino, and τ neutrino), and each neutrino has its corresponding antimatter.

But at present, there are still many mysteries about neutrinos.

First of all, the mass of neutrinos has not been directly measured, and their size is also unknown.

Second, it is not known whether the neutrino and its antiparticle, the antineutrino, are the same particle.

Third, there are two parameters of neutrino oscillations that have not been measured, and these two parameters may be related to the mystery of the absence of antimatter in the universe.

Fourth, whether neutrinos have magnetic moments or not, and so on.

In the real world, as long as one of these questions can be answered, the Nobel Prize is basically a matter of hand.

……

It took Pang Xuelin a week to finish a hundred papers, and he found that he had accumulated more problems in his mind.

The world's research on neutrinos is far more in-depth than he imagined.

He had to put the neutrino detector aside and focus back on the mission.

Fortunately, the world is not much ahead of the real world in the research of quantum computers and artificial intelligence.

As a result, the world's network is one-way transparent to MOSS mounted on a quantum computer.

By hacking into the databases of the CIA and FBI, as well as the information queried from the dark web, Pang Xuelin basically grasped the general information of Uncle Werner's drug trafficking network.

In addition, he also has a further understanding of the "Poseidon" program of the US military.

Since David Hopkins left the U.S. military's research institute, the U.S. Navy has not completely terminated the "Poseidon" program, but has maintained a small research team.

The team is currently affiliated with the U.S. Naval Research Laboratory (NRL), and their experimental base is actually located in a bay not far from Los Angeles.

The base is also home to more than a dozen dolphins and sharks that are equipped with electrodes and control systems.

……

A week later in the evening.

"Professor Pang, this is what I found out about David Hopkins and Werner Jr. through surveillance and the Internet. Werner Jr. posted a bounty on the dark web a week ago, the goal of which is to find a safe route to the United States without passing through the neutrino detector, the reward amount is as high as 50 million US dollars, and I also found the account of Davy Hopkins on the dark web, he seems to be trying to make a lot of money with the blue whale "Poseidon" he controls, but he has not found a suitable way to do so. I don't think it won't be long before Hopkins sees Werner's bounty. ”

Pang Xuelin nodded, and did not explain how Hopkins connected with Werner Jr., after MOSS's investigation, Pang Xuelin understood.

Although David Hopkins is currently a professor of marine biology at the California Institute of Technology, he is not well-known in the academic community, and marine biology is not a popular major, so David Hopkins' income is relatively limited.

But not long ago, his wife divorced him and took a large amount of property.

As a result, Hopkins' financial situation is very tight, and it has reached the point where he can't afford to pay off his credit card.

It just so happened that little Werner posted such a message on the dark web, and after David Hopkins saw it, his heart was normal.

Pang Xuelin lowered his head and pondered, he was thinking about the next course of action.

In order to complete the system tasks, there are two main problems.

First, how to destroy Werner's yacht.

It is not realistic to let Pang Xuelin sneak in and launch an attack secretly like a special forces frogman.

Secondly, how to gain control of "Poseidon", the latter is even more important than the former.

Because according to Pang Xuelin's plan, if he wants to destroy Werner's yacht, "Poseidon" will play a crucial role.

It's just that until now, MOSS has not found the control method of "Poseidon" in Werner's computer, and there is not even any information related to "Poseidon", so if you want to get "Poseidon", you must kill Davy Hopkins, you have to find another way.

"MOSS, YOU TAKE OVER HOPKINS' COMPUTER FIRST SO THAT HE CAN'T VIEW LITTLE WERNER'S BOUNTY ON THE DARK WEB. At the same time, you post a bounty similar to Werner Jr. on the dark web, and then show it to David Hopkins in due course. ”

MOSS: "Professor Pang, are you going to fish for law enforcement?" ”

Pang Xuelin was slightly stunned and laughed: "Yes, it's fishing law enforcement." ”
