I have recently reviewed the history of quantum physics (I have read it once before and strongly recommend it, which may change your entire world view ), quantum theory is used to solve a world-famous "zhinuo paradox". The content of this paradox is as follows:
Achilles is a Greek hero in the epic Iliad. One day when he met a tortoise, the tortoise laughed at him and said, "Everyone else says you are amazing, but I think if you are racing against me, you will not be able to catch up with me ."
"How is this possible. Even if I run slowly, the speed is 10 times faster than yours. Why can't I catch up with you ?"
The tortoise said, "Okay, let's assume. You are 100 metres away from me, and you are 10 times faster than me. Now you are chasing me, but when you run to my current position, that is, when you ran 100 meters, I ran another 10 meters. When you catch up with this position, I ran another 1 meter forward, you chased another 1 meter, and I ran another 1/10 meters ...... In short, you can only approach me infinitely, but you can never catch up with me ."
Q: How can I hear about achilith? I am confused by the second monk.
This is a correct answer for elementary school mathematics. But what is the point?
If you understand the problem correctly, it is estimated that most people cannot tell where the tortoise is wrong, but if you use calculus, it is correct to verify the tortoise.
In quantum theory, this problem can be easily solved, because quantum theory deems that space in the real world is not continuous, and it is not infinitely severable. It must have a minimum value. The theory of turtles is based on the ideal space that is infinitely severable, but in fact, distance (Space) has a minimum value, when the distance between Achilles and turtles reaches this minimum value, and the minimum value cannot be further divided, then Achilles naturally catches up with the turtles.
In fact, in this special case, the minimum value is the step size of the tortoise. What if we replace Achilles and turtles with two different rolling balls with different speeds? There are still some minimum values, that is, a distance quantum (the specific value does not need to be concerned ).
I did not expect a question that was answered a thousand years ago. If we are more intelligent, we can use this paradox thousands of years ago to draw a quantum theory where space is not infinitely severable. However, it is a pity that the people who raised this question a thousand years ago (barmenide) came to the conclusion that "existence" is absolutely static, and that sports are absurd. The movement we understand is just a false one. (Is it true that this is true ?)
The Zeno paradox reveals that space is not an infinitely severable nature. So is there any paradox that can reveal that time is not the essence of infinite differentiation? The answer is yes. This is also the well-known "Paradox of flying and moving". The content of this paradox is as follows:
A flying arrow is static.
Because the arrow has its fixed position at every moment, it is still, so the arrow cannot be in motion.
With the foundation above, it is easy to point out the true paradox of the flying Vector Based on quantum theory, that is, it assumes that time is infinitely severable like the zhino paradox. Because we assume that time is infinitely severable, the arrow position remains unchanged between the time points of each phase that can be infinitely divided, and all the time points are connected, the arrow becomes absolutely static. However, quantum theory tells us that time is not infinitely sharded, and there is a minimum value. It is easy to do with a minimum value. The arrows actually have a passing time between the two minimum values in phase sequence, that is to say, the arrow is in different positions. Now we can see why the arrow is not static but moving.
If you haven't understood it yet, read it several times, because many world-class scientists have been confused in quantum theory, including Einstein.
It will certainly be interesting to understand it. There are many interesting aspects in quantum theory, and I will share them with you later.
