[Full text] Before the first emperor started his business, the Middle Road collapsed. The next three points, Yizhou exhausted its disadvantages, is also a crucial autumn. But the guards worked tirelessly at home, and those who were loyal to their ambitions forgot to be outside, covering up the special experience of the former emperor and wanting to report to your majesty. Sincerely, it is advisable to open a holy court, with the honor of the late emperor and the spirit of the people. It is not advisable to belittle yourself, quote wrong words, and block the way of advice from loyal ministers.
In the palace, everything is an organic whole and should not be punished or denied. If there are criminals who are honest and kind, they should be rewarded by this department to show your majesty's understanding, and you should not favor one over the other, making the internal and external laws different.
Question 3: Ask others, what does good mean? It comes from "mode" and generally refers to being good at listening to other people's opinions.
My personal opinion, I hope the landlord will adopt it.
Question 4: We can find that the data of relativity may be somewhat repetitive, but it is by no means copied upstairs.
Relativity is a basic theory about space-time and gravity, which was mainly founded by Einstein. It can be divided into special relativity (special relativity) and general relativity (general relativity). The basic assumptions of relativity are the principle of invariance of light speed, the principle of relativity and the principle of equivalence. Relativity and quantum mechanics are two basic pillars of modern physics. Classical mechanics, which laid the foundation of classical physics, is not suitable for high-speed moving objects and objects under microscopic conditions. Relativity solves the problem of high-speed motion; Quantum mechanics solves problems under microscopic subatomic conditions. Relativity has greatly changed the common sense concepts of the universe and nature, and put forward new concepts such as simultaneous relativity, four-dimensional space-time and curved space.
Theory of relativity
An incredible world.

Interpretation of basic concepts of general relativity;
Before reading this passage and understanding the key features of general relativity, we must assume one thing: the special relativity is correct. In other words, general relativity is based on special relativity. If the latter is proved wrong, then the whole theoretical building will collapse.
In order to understand general relativity, we must know how mass is defined in classical mechanics.
Two different expressions of quality:
First of all, let's think about what quality stands for in our daily life. "Weight"? In fact, we think that mass is something that can be weighed, just like we measure it: we put the object that needs to be measured on the balance. What kind of quality do we use to do this? It is the fact that the earth and the measured object attract each other. This mass is called "gravitational mass". We call it "gravity" because it determines the motion of all stars in the universe: the gravitational mass between the earth and the sun drives the earth to move around the latter in a nearly circular motion.
Now, try to push your car on a flat ground. You can't deny that your car strongly resists the acceleration you want to give it. This is because your car is of great quality. It is easier to move light objects than heavy ones. Mass can also be defined in another way: "It opposes acceleration". This mass is called "inertial mass".
So we come to the conclusion that we can measure quality in two ways. Either we weigh it (very simply) or we measure its resistance to acceleration (using Newton's law).
Many experiments have been done to measure the inertial mass and gravitational mass of the same object. All experimental results come to the same conclusion: inertial mass is equal to gravitational mass.
Newton himself realized that this kind of mass equivalence was caused by some reason that his theory could not explain. But he thinks this result is a simple coincidence. On the contrary, Einstein found that there is a channel in this equation that can replace Newton's theory.
Everyday experience proves this equivalence: two objects (one light and one heavy) will "fall" at the same speed. However, heavy objects are subject to greater gravity than light objects. So why didn't it "fall" faster? Because it is more resistant to acceleration. The conclusion is that the acceleration of an object in the gravitational field has nothing to do with its mass. Galileo was the first person to notice this phenomenon. It is important for you to understand that all objects in the gravitational field "fall at the same speed" are the result of the equivalence of inertial mass and gravitational mass.
Now let's pay attention to the expression "whereabouts". Objects "fall" because the gravitational mass of the earth produces the gravitational field of the earth. Two objects have the same speed in the same gravitational field. Whether it's the moon or the sun, their acceleration speed is the same. In other words, their speed increases by the same amount every second. (Acceleration is the increment of speed per second)
The third hypothesis in Einstein's argument is that gravitational mass and inertial mass are equal.
Einstein has been looking for the explanation that "gravitational mass equals inertial mass". To this end, he put forward a third hypothesis, called "equivalence principle". It shows that if an inertial system is uniformly accelerated relative to a Galileo system, then we can consider it (inertial system) to be stationary by introducing a uniformly accelerated gravitational field relative to it.
Let's examine an inertial system K', which has a uniform acceleration motion relative to Galileo system. There are many objects around k and k'. This object is stationary with respect to K, so these objects have the same accelerated motion with respect to K'. This acceleration affects all objects ... >>
Question 5: Look up the Chinese characters of the yayan idiom. Look up the Yayan character and use the correct remarks. Interpretation of words: inspection and adoption. Elegant character: correct opinion: adopt the combination of idiom nature, commendatory words and idiom usage; As predicate, object, attribute and adverbial. As the king of a country, it is necessary to be polite to make sentences in order to be loved by the people. The origin of the idiom is 1, Three Kingdoms? Shu? Zhuge Liang's "Demonstration": "Your Majesty should also ask for it himself, consult the good way and judge the elegant words."
