Speed, out of time. 10. Speed, no time.

Strip. Hurt Zhongyong.

Wound Zhongyong is an essay written by the Northern Song Dynasty writer Wang Anshi. tells the story of a prodigy named "Fang Zhongyong" from Jinxi, Jiangxi Province, who was reduced to an ordinary person because his father did not let him study and was used by his father as a money-making tool. Taking Zhongyong as an example, the article warns people that they must not simply rely on aptitude without learning new knowledge, but must pay attention to acquired education and learning, emphasizing the importance of acquired education and learning for becoming talents.

Wound 1 Zhongyong. Jinxi 2 people Fang Zhongyong, Shili 3 ploughing. Zhong Yongsheng 45 years, did not know 5 books 6, and suddenly begged for 7.

The father is different from 8, borrowing nearly 9 and 10, that is, four lines of poetry, and its own name. His poems are based on adoptive parents 11 and 12 families 13, and 14 townships show talents. Since it refers to 15 things as poems16, and its texts 17 and 18 are all observable.

The people of Yi 19 odd 20, slightly 21 guests 22 their fathers, or 23 beggars in coins. Father Li Qiran 24 also, day 25 pull 26 Zhong Yonghuan 27 Yu 28 Yu Yi people, do not learn.

I have heard it for a long time. In Mingdao 29, from 30 ancestors 31 returned home, and saw it at the uncle's house, twelve or thirteen. Ordering poetry cannot be called the news of the past.32 For another seven years, he also went to his uncle's house from Yangzhou and 33 to ask questions. He said, "Nothing is clear to everyone.34 “

Wang 35 said: Zhongyong Zhitong 36 enlightenment 37, 38 heaven 39 also. The day of its acceptance is also, Xian 40 is far away from 41 materials and 42 people.

43 and he who died of 43 is many, and he who receives 44 is not 45. He is 46 the heavens that receive it, so that it is virtuous, and he who does not receive it, and he is many; The man who does not receive it will strengthen the people, and the one who will not receive it will be for the people.47 Yah, 48?

Yes, because sometimes I feel like the day goes by very quickly, and sometimes it feels very slow.

Time has no speed, time is just a jujube song unit of measurement, time itself does not exist, only because of the comparison of events, people conceived the concept of time.

Time has no speed. Because people can't directly observe time. The present time is only a reference to an object.

To put it simply: you are based on the idea of traditional physics: that is, the "irreversibility of time" that space-time is divisible; But in Einstein's theory of relativity, time is reversible, space-time is inseparable, in this case, velocity affects time, and there is no time without velocity.

If the universe had no speed, there would be no Earth. "Speed" itself is a "space-time" concept. If you put aside the concept of "space" and only talk about the relationship between "speed" and "time", it is also an inconsistency statement.

Actually, speed is a relative quantity. In fact, you confuse the difference between "speed" and "rate" in your statement.

Velocity is a vector, and both average and instantaneous velocity are vectors. The only criterion for distinguishing velocity from velocity is that velocity has magnitude and direction, and velocity has magnitude and no direction.

Looking at the theory of relativity, for people in one speed system, their time does not change, but for people in another system, they pass time at different speeds, each walking an hour relative to himself, and in reality an hour on one side may be two hours for the other.

The clock is just a tool to measure time, what is the relationship between speed and time?

The two of them saw each other's car lengths, so Xiao Zhang saw 120 meters, and Xiao Biqiao Pants King saw that Jane was 150 meters, because the relative speed of the two was the same, and they were both the sum of the speeds of the two cars; Therefore, the ratio of time for the two to see each other's cars is the ratio of each other's car length, so Xiao Zhang saw 8 seconds, and Xiao Wang saw 8 120 150 = 10 seconds.

Let the distance from A to B be l, then: the drift from A to B is l v.

There is a downstream flow: l u+v=3, that is: 2l=6u+6v upstream:

l u-v=6, i.e.: l=6u-6v, will be formula: 2l=6u+6v minus formula:

L=6U-6V gives L=12V, and substituting L=12V into L V gives 12Vv=12 hours.

t1=s/(u+v)

t2=s/(u-v)

u+v=s/t1

u-v=s/t2

Subtract the two formulas: 2v=s t1-s t2

s/v=2/(1/t1-1/t2)

2/(1/3-1/6)=12 h

How many 12 hours does it take to drift from A to B

According to the known conditions, according to the formula: s=vt, and calculate the t. in it

The theory of relativity holds that "time is only a subjective reference to the feelings, not an objective existence". Velocity is a physical quantity defined by a ratio.

The physical dimension of time is "seconds". If time has "speed", who does it compare with, and who compares with it?

"That is to say, time is the same, but when it is faster, it magnifies time and slows down."

This statement is not true. In the range well below the speed of light, a higher velocity only indicates that the object has passed more units of space in fewer units of time. It does not measure the unit of space in terms of the unit of time, and it cannot measure the unit of time in the unit of space.

Because at low speeds, the rate of time is equal on any object, and the clock placed on a fast trolley travels at an equal rate with a clock placed on a slow trolley, regardless of the speed of the trolley.

In addition, the statement that "time is the same as the same progress" is inherently wrong. Regardless of the typo, how can the discussion time be evaluated in terms of the concept of "simultaneous"? You can measure and calculate the rate of time, define the direction of time, but talking about time itself in terms of the concept of "simultaneity" is inherently a logical loop.

According to Einstein's theory of relativity, when the speed is greater than the speed of light, time will be reversed."

There is no such thing in the theory of relativity, which is a false proposition.

Is that the fastest speed of light as a reference, the object is infinitely close to the speed of light, time will only be relatively slower and slower, when it is greater than the speed of light, there is a fixed value, and time will be reversed."

At present, there is no such theory in physics as "the behavior of objects greater than the speed of light". Some equivalent "faster-than-light" effect may be discovered in the future, but it is too early to discuss these.

Is it all relative?".

The theory of relativity simply gives a method for analyzing the state of motion between different frames of reference in the field of physics, rather than the philosophical extrapolation-like speculation that purely discusses velocity as described above. A distinction should be made between the concept of "relative" in physics and the concept of "relative" in philosophy, the former must have a definite physical meaning, and the latter is much broader.

I recommend two books, one is called "The Shape of Time" and the other is "Let's Talk about Special Relativity", which is a very good popular science book about the theory of relativity in the past two years. I suggest you take a look at it, and don't just hear a few words about the theory of relativity and think about it.
