The differential problem of university physics
In university physics, differential equations were very important.
Speed was the derivative of displacement versus time. In a geometric sense, the derivative (speed) of a function (displacement versus time) reflected the instantaneous rate of change of the function at a certain point, which was the slope of the displacement versus time curve at a certain point. For example, in a free-falling motion, if the displacement function is <<s =<frac>{1}<2}>^{2}>, the velocity can be obtained from the derivative definition <v =<<p>>.</p>
Acceleration was the derivative of speed with respect to time. It described the instantaneous change in speed. For example, for uniform linear motion, the velocity function is a constant, and the acceleration is a constant.
The function of the differential equation in the analysis of kinetic problems was also reflected in the detailed description of the motion process. For example, in complex variable speed motion, by differential analysis of physical quantities such as displacement or velocity, one could more accurately study the motion state of the object at each moment and the relationship between the physical quantities. This would help to solve problems such as the instantaneous velocity and acceleration of the object at a certain moment, which would lay the foundation for further analysis of the object's motion trajectory and energy change.

What was the physics knowledge in " The Three-Body Problem "?
" The Three-Body Problem " was a science fiction novel by Liu Cixin that described the communication and conflict between humans and alien civilizations. Some physics knowledge was involved in the novel, such as:
1. Gravity: The novel described that the Tristani came from the Tristani Galaxy, where the planets had a strange gravitational force that forced the Tristani to use a special method to move. In physics, gravity was a force that described the interaction between objects. It was the foundation of Newton's mechanics.
2. Quantum physics: The novel involves quantum physics knowledge such as quantum entanglement, quantum tunnelling effect, and quantum teleportation. These concepts were very basic and important in physics, and they were very helpful in understanding the behavior and thinking of the trisomatics.
Cosmology: The novel also involves the knowledge of Cosmology such as the expansion of the universe, black holes, dark matter, and dark energy. These concepts were very important for understanding the nature and evolution of the universe.
4. Life Physics: The novel described the form and evolution of the trisomatics, including their cell structure, metabolism, and evolution. Life physics is a fundamental subject that studies the phenomenon of life. It is very important to understand the nature and evolution of life.
The physics knowledge in " The Three-Body Problem " involved many important physics concepts and theories. This knowledge was very helpful in understanding the plot and characters in the novel.

What's the problem with the slow response of the loading machine?
The reasons for the slow gear shift of the tractor were as follows:
1. Low oil pressure: Low oil pressure will cause the main oil pressure to be insufficient, causing the working oil pressure to fluctuate, thus affecting the gear shift response speed. Usually, it takes 3 - 4 seconds to start. This may be caused by the low oil level, which can be solved by adding the right amount of oil to the clutch. When selecting oil, it is advisable to choose high-quality oil to provide better power support for the engine and clutch.
2. Worn out oil pump of the tractor: Worn out oil pump will result in slow gear shift response, and the tractor oil pump needs to be replaced. Before the replacement, the damaged old oil pump needed to be removed and a new oil pump needed to be installed with the help of relevant tools.
3. The gear teeth were severely worn: this situation could also cause the gear change to be slow.
4. The transmission oil is not enough or the transmission oil filter is blocked: this will affect the gear shifting speed.
5. Clutch problem: For example, the clutch problem during the same gear, you can use the short inertia of reversing the gear and stepping on the brake to change the first gear.

The machine has a problem. How do you say it in English?
The following English expressions could be used for machine problems:
1. break down, as in "My car has broken down." (Used for machines, vehicles, etc. to break down or malfunction. It can also indicate the collapse of a person's mental and physical strength.)
2. There's something wrong with...，For example,"There's something wrong with the electric cooker."
3. machine stop page (more formal, used in economic, industrial, and other fields to describe the machine stopping);
4. machine fault or machine error;
5. On the blink, for example,"Too bad, the coffee maker is on the blink again."

What was the experience of a physics major reading science fiction novels like " The Three-Body Problem "?
Physics majors might be surprised and shocked when they read science fiction novels such as the Three-Body Problem because these novels contained many basic principles and concepts of physics such as the Dark Forest Theory, the Three-Body Problem, gravitational waves, and so on.
They may find that the physics concepts in these novels are very similar to their professional knowledge, but there is a broader application and explanation space. At the same time, they might also question the fictional technology and scientific assumptions in these novels and consider the possibility and feasibility of these assumptions in reality.
Reading science fiction could be an opportunity for physics majors to explore the unknown world and expand their knowledge.

Is cartoon physics stronger than anime physics?
Cartoon physics can often be more fantastical and over-the-top, making it seem stronger. However, anime also has its moments of intense and creative physics, so it's not a clear-cut answer. It all comes down to the specific shows and their creative directions.

Why did the Three-Body Man in " The Three-Body Problem " kill the basic physics scientists on Earth?
In " The Three-Body Problem ", there was no clear answer to the question of why the Three-Body Man wanted to kill the basic physics scientists on Earth, but it could be considered from the plot and logic of the novel.
In the novel, the trisomatics were described as a highly civilized alien creature with powerful technology and the ability to understand human thoughts. When facing the scientists on Earth, the Three-Body People showed a strange fear and hostility. They believed that the scientists on Earth would threaten the survival of the Three-Body People. Therefore, they tried to kill the fundamental physics scientists on Earth to eliminate this potential threat.
In addition, the novel also mentioned that the existence of the Three-Body People on Earth was affected by some factors that forced them to come to Earth and attack humans. Therefore, killing the basic physics scientists on Earth might be a means for the Trisolaris to try to eliminate the influence of this factor.
It should be noted that the plot in the novel was fictional and not a real historical event. Therefore, the plot in the novel should be viewed rationally and not as a reference to reality.
