Quantum mechanics characterizes how time comes about

The uncertainty of energy and time.

It is not deduced in this way, it is at most a means to help you understand, and if any book claims that it can be used to introduce the uncertainty of energy time, it is irresponsible for the person who wrote the book.

How did this formula come about? Very simple.

Suppose the system has two energy eigenstates, ·|e1>, e2>

The general state of the system is evolved over time, which can be written as.

c1exp(-ie1t/h)|e1>+c2exp(-ie2t/h)|e2>

For wave functions.

It is possible to differ by an overall phase.

That is, when two exponential functions.

When the phase difference is the same as the initial, the wave function of the system returns to its original state, and the phase difference is a periodic function with a period of 2pi.

And then there's the formulas you wrote.

In fact, you can analyze that the simplest harmonic oscillator model and a one-dimensional square potential well, no matter how many energy levels are superimposed, there is a maximum period, especially in the case of harmonic oscillators, this period and the period of the harmonic oscillator are the same, so you can call the characteristic time of the system.

This should be a relevant inference of the quantum properties of position and momentum in the uncertainty principle: that is, energy and time cannot be accurate at the same time, and some books may not talk about the relationship between energy and time in quantum physics.

A new study shows that the flow of time at the quantum level does not necessarily have only one direction. In some environments, it is possible for quantum system software to move forward and backward in time. It was a very exciting discovery.

We're not talking about time travel machines or the quantum industry of the Marvel Cinematic Universe here. However, at the level at which we stand, how we perceive time may not be entirely the true essence of time.

One of the biggest mysteries in the universe of time. We've all experienced it, and we all know that it works in a certain way, in the same direction from the past to the future. This particular direction—which is called the arrow of time—is related to the concept of entropy, which is a measure of the disorder of a system's software.

In a self-contained system, such as our universe, entropy will always increase, and the direction of ascension will coincide with the direction of time passing.

According to the journal Communications Physics, researchers observed that the entropy shift was not significant. Depending on the fundamental properties of quantum structural mechanics, entropy may decrease spontaneously (as in the case of time regression). They also make use of another important quantum mechanical property:

Accumulate. In such a situation, your physics system can be equipped in a variety of configurations. "If a situation creates a lot of entropy, it is so unlikely to observe it being flipped in duration that it is inherently impossible.

> However, when the entropy generated is sufficient, of course, the probability of a time flip is not negligible. Dr Julia Rubino, a key creator at the University of Bristol, said in a statement. He said

You can take the logical order of the morning as an example. If we were to see their whitening toothpaste move from the soft-bristled toothbrush back into the toothbrush's pipe, we would undoubtedly see that this is our day's rewind recording. However, if we slowly squeeze the toothpaste tube and only a small part of the whitening toothpaste goes out, it is unlikely that we will observe the whitening toothpaste entering the tube again and being inhaled according to the relieving pressure of the tube.

> an international elite team observed a kind of quantum accumulation, which has not only a backward trend in time, but also a forward development. They found that, in general, this could lead to a shift in time. But for a small entropy shift, the system software can continue to evolve forward and backward in time.

This work is biased towards a great unknown, and that is time at its most basic level. The scientific study suggests that there may be less and less knowledge about it than we previously thought. "Although duration is often referred to as a growing major parameter, our research shows that the flow of time is much more complex in the context of quantum structural mechanics.

This may suggest that we should rethink the way in which this quantity is revealed in all the natural worlds in which quantum fundamental laws play a dominant role. Dr. Rubino concluded.

Of course not. In the world of quantum mechanics, time does not exist at all, and it is impossible to distinguish the specific direction of flow.

Yes, after all, there is no time limit in the study of quantum mechanics, so there is no trajectory of motion.

Yes, it does, motion in the quantum world does not take time.

100 After the advent of the special theory of relativity (SR), people realized that time is no longer a simple dimensional general relativity (gr), and after the advent of the general theory of relativity (gr), people said that time and space are one, and it is called four-dimensional space-time, which is expressed in general relativity, and they are four-dimensional manifolds In Einstein's understanding, space-time is flat, that is, he thinks that time is continuous This may seem like a true view, but if you think about Zeno's paradox, the athlete and the tortoise race if time is continuous, Athletes will be proven to never outrun the turtle Stephen Hawking once said that time is not flat, it has a lot of folds and cracks on it and things like wormholes, which people call quantum bubbles. But if time is quantized, then it has a basic unit, then for a moving object, every basic unit of time is stationary, so why is a large number of stationary events connected together in motion? (See Zeno Paradox for details) In other words:

If time is quantized, then what makes motion? Besides, if time is quantized, then both theories of relativity will have to be rewritten, not to mention that both relativity and quantum mechanics have an indelible infinity, and neither of them looks like the ultimate truth (they are all image-only) and the current M theory is still not mature, and the problem of supersymmetry remains unsolved. I don't know what the fate of the M theory will be, and I can't be sure if he will be the truth.

I've heard that time seems to have a minimum unit, like 10 -34 s or something, but is the answer to this question in a superposition similar to that of Schrödinger's cat? Is it somewhere in between? Wait for the expert to answer ing....

Addendum: The one on the first floor is a bit like what Kant's "Critique of Pure Reason" wrote, but I guess what you want to clarify is the view of Buddhism or Zen, which advocates that the bird is to return to the heart to find the answer, but this requires the shocking guessing belt at the bottom of life to catch up with the "original consciousness", and then find the ultimate answer that science can't solve. If you think that things only exist under human cognition, then who asks this question?

According to the famous theory of relativity, if there is time, then there must be space, and the combination of the two forms the so-called time and short. The famous physicist Fidoke believes that space-time has a great relationship with quantum mechanics, because space-time is composed of quantum particles. Take a smooth stone distance, from the appearance of the macroscopic point of view, it is very smooth and a whole, but from the onlooker's point of view, it is composed of countless particles, which is the same as the time and space we live in, from the overall point of view, it is a smooth whole, but from the point of view, it is composed of countless quantum particles in the bright posture, and these quantum particles are also made up of space-time atoms by Fidoch.

What is time? Physicist: In quantum mechanics, time is made up of space-time atoms.

So how small are space-time atoms? Since it is a space-time atom, then it must be composed according to our time, the middle bond beat is like a stone is composed of carbonate particles, and the sugar cube is composed of sugar molecules, so the unit of space-time atom is also a unit of time, but this time unit is incredibly small, as small as a million trillions of a second, and this is also the smallest unit of time that Fiddock thinks, and it cannot be smaller. The passage of time is composed of this space-time atom, that is to say, the past is the part of space-time atoms that have been composed, and the present is the part of space-time atoms that have not yet been composed, and the future is the part of space-time atoms that have not yet been formed, that is, just like a water pipe, when you turn it on, the place where the water has passed is the past, and the place that is passing through is the present, and the place that has not passed is the future.

The name sounds very mysterious, but it's actually very simple, an electron moves in an electrostatic field, and if the direction of the terminal velocity is reversed, then it will return to the initial position according to the original path, as if the film is upside down. In other words, the reverse evolution of time is also a way of motion that follows all the laws, corresponding to the situation that the direction of motion is reversed at every moment. If a person jumps from the upstairs in the film, in the absence of air resistance, the film is upside down**, as if the person jumped from the ground to the upstairs, and the audience of the **film can't see any problems, because there is no resistance, the positive and negative** follow the law of motion, which means that the person jumping from the upstairs is time reversal symmetry.

But if a girl in a skirt jumps down from upstairs, because of air resistance, the skirt will float up, and if the film is upside down, there will be a problem, how can the skirt float upstairs when jumping upstairs, that is to say, in the case of resistance, jumping from the upstairs is not time reversal symmetry.

In the same way, the evolution of states over time in quantum mechanics is the same, and if the evolution of time in reverse can also be an actual evolutionary process, it is said that this quantum mechanical process has time reversal symmetry.

There is no corresponding conservation law for time-reversal symmetry in quantum mechanics!! In classical mechanics, due to the existence of the second law of thermodynamics, the inversion symmetry of time will mean that the entropy will spontaneously decrease, and the arrow of time will be reversed, which will violate the second law of thermodynamics. This is also an important difference between quantum mechanics and classical mechanics.

Therefore, in the macrocosm, the little girl jumping up and down always fails to meet the symmetry of time reversal

In both classical and quantum physics, the concept of the evolution of time is everywhere. We are already very familiar with the determinism of the Newtonian system, and although quantum physics rejects this determinism, the quantum mechanical system still uses the concept of time evolution, which is very important in determinism.

In the quantum mechanical system, there are two equivalent descriptions of this temporal evolution, namely Schrödinger and Heisenberg. In the former, the mechanical quantity (operator) is fixed, while the quantum state of the system evolves with time; In the latter, it is the mechanical quantity (operator) that evolves, and the state of the system does not change. Although, mathematically, they can be converted into each other, but in physics they seem to be different.

Let's start with the upstairs. Upstairs, m is quantized, and p is also quantized. Indeed it is.

m is quantized, indeed weird. But you have to consider that m is the moving mass in the mass-energy equation, and the moving mass is related to the velocity and the static mass. Although the static mass is not quantized, the velocity is quantized, resulting in the dynamic mass being also quantized.

Let's talk about your questions again. Time quantization is wrong. The inference that the frequency is quantized is correct.

However, the inference process should not be corrected by dimensions, but by physical formulas. The correct conclusion is that the frequency is the reciprocal of the period, so the period is quantized. And not time.

According to a report published in Global Technology in 07 (or 06), according to the quantum theory of circles (similar to string theory), time is discontinuous, that is to say, the next second and the previous second are discontinuous, about 10 to minus 33 to minus 34 seconds, that is to say, time is discontinuous, but it does not mean that it is ionic. These are the conclusions of theoretical physics, and there is no experimental proof for the time being

Time cannot be subdivided, so time is not quantized in any way.

Time is the quantity introduced by humans to characterize the change of matter, there is no time without change, and time without matter is meaningless.

If e=mc 2 and c are fixed values, as you say, can we say that m is also quantized? m=pv, does that mean that p is also quantized?
