Are there two exactly the same things in the world?

To be precise, there are no two identical things in the world, even if they are twins, they cannot be exactly 100% alike, they are only visible to the naked eye, and there are never two identical leaves in this world.

Strictly speaking, there are no two exactly the same things in the world, this is because even if they are the same kind or the same type of things, they often have internal differences, although on the surface you may not be able to see the difference, but in fact, in their delicate texture, in his inner thoughts, these may be different, and these are often impossible for us to **, so there are no two exactly the same things in the world.

Any two things, even if they look very similar in some ways, will always have some differences in others. This is because each thing has its own unique attributes, characteristics, history, and environment, and these factors affect their performance and behavior.

For example, even if two stones look very similar, they will have some minor differences, such as their color, weight, shape, and texture, etc. Similarly, even two identical people have different DNA because they are made up of different chromosomes and gene sequences.

Therefore, it can be concluded that there are no two things in the world that are exactly the same, as each thing has its own unique properties and characteristics.

From the point of view of contradiction, contradiction is special, and all things are different.

The particularity of contradiction and the universality of contradiction are interlinked.

No two things in the world are exactly the same, and no two completely different things exist.

It's just that the objects of the macrocosm are so. It's not the same in the microcosm – for example, can you say that two electrons are not the same? Some people have retorted that the electrons are bosons and follow the Pauli incompatibility principle, so two electrons in the same orbital are different.

Note, however, that this is not "not the same" as we usually understand it. According to the landlord, the difference in macroscopic objects not only refers to the difference in position, but also refers to the perceptible difference in physical properties between themselves. For example, if different objects are in the same position in the same system, they will definitely cause a physical property of the system to be different, just like two books with different qualities, put in the same bag, will lead to different total mass of the entire "package + book" system.

But any electron, put in the same orbital, behaves the same. A hydrogen atom does not make any difference in physicochemical properties just because its electrons originally came from a gold atom or a magnesium atom. This already shows that all electrons are equal.

Of course, it can be considered that this "the same kind of particles in the microscopic world are the same as each other" is a theoretical construction; However, if one holds a realist view that these scientifically constructed particles are real things, then it is certainly wrong to say that there are no two things in the world that are exactly the same.

Philosophers have long told us the answer: we cannot step into the same river at the same time.

And from the point of view of the development of physics, this is also proven.

Classical physicists represented by Newton pushed classical physics to the highest peak, and one of the most important concepts of classical physics is that if the same initial conditions are given (but strictly speaking, there is no absolute sameness in the exact sense), then the results will be exactly the same, that is, if we know the initial conditions, we can all predict the development of the motion of all things like the prophets in mythology- Newton was enshrined as a god-like figure because she predicted the existence of an unknown planet (I forget which one) based on her own set of theories. Physics seems to have reached the era of "great unification".

But at the beginning of the 20th century, this era of "great unification" returned to the era of "Warring States Division", because of the emergence of quantum mechanics, "prediction" (ironic enough) that there is no such thing as absolute, in other words, continuing with the above example, even the same initial conditions are debatable (there is a "uncertain" principle in quantum mechanics, you can take a look at it if you are interested), not to mention that the same results can be obtained.

It is impossible to toss a coin to ensure that it will be heads every time, and it is the same, more complicated, it is impossible to have two identical rains, because so many raindrops have to ensure the full size, speed, position, and direction. It's all the same, and almost even the gods have to frown. Moving on, matter is made up of atoms, and who can guarantee that two things will be "cloned" on an atomic scale?

In fact, there is a structure inside the atom, which is not the same.

So, everything in the world is unique. Think of a stranger who passed by at an inadvertent moment in your life one day, in fact, he was also "carefully selected" from 6 billion human beings, just to have such an insignificant glimpse with you - no wonder the Buddha said that 500 times of looking back in the past life was exchanged for a brush in this life.

Everything in the world is bounded between contradiction and non-contradiction. But this contradiction and non-contradiction are relative, not absolute. Different positions, different answers and perceptions. Because people have thoughts and think the most, people are relatively the most contradictory.

a Unique expression of human life. (1) The uniqueness of human life is prominent: compared with other animals, plants, microorganisms and other life, human life is the most intelligent.

2) The uniqueness of human life is more manifested in the diversity of people's personality qualities, life paths, and ways and means to realize the value of life. In the question, "No two leaves in the world are exactly the same" illustrates the uniqueness of life.
