The uncertainty principle was proposed by the famous German physicist Heisenberg. The uncertainty principle is that for microscopic particles, its velocity and position cannot be accurately measured, and the more accurately one of the physical quantities is measured, the more obscure the other is, and the product of the error of the two is greater than h/4π (h is Planck's constant).
The uncertainty principle was shocking when it was first proposed, because for thousands of years people have lived in a world of certainty. In particular, Newton's classical physics, time, space, matter, etc., all physical quantities can be measured precisely.
Heisenberg's explanation of the uncertainty principle is that during the measurement process, people inevitably interact with the measurement object. At the very least, a photon is also needed to probe him. In the measurement process, it is inevitable to interfere with the measuring object, so it is impossible to achieve accurate measurements. This disturbance theory once dominated. However, Bohr, the leader of the Copenhagen School, was dismissive of the disturbance. He argues that the reason for inaccuracy is not because of perturbation, but because inexpensiveness itself is one of the profound laws of the universe. He argues that Heisenberg's uncertainty principle, derived from series, is based on a premise that is only a mathematical hypothesis and therefore cannot be used as a precondition for the most fundamental principle of the universe. He believes that the explanation of the uncertainty principle should start from the nature of the universe. And he thinks that this essence is wave-particle duality. He believed that everything in the universe, whether macroscopic or microscopic, was wave-particle dualistic. That is, there are both the characteristics of waves and the characteristics of particles, which is how things exist. In the observation of wave-particle duality, human consciousness causes the collapse of the wave or particle state, thus creating uncertainty in the measurement. In this way, for the uncertainty principle, the Copenhagen School, after a circle, returned to the origin of consciousness. Consciousness's participation in the material world has always been a core criterion of the Copenhagen School.
With the development of physics. Increasingly, the characteristics of fluctuations in the entire universe have been discovered, and the material waves of De Broglie in particular have made macrophysical fluctuations more explicit. At the same time, with the advancement of experimental means, people have successfully realized double-slit interference experiments by entangling photons. It can be said that the success avoids interference. However, microscopic particles were still found to be successful in hiding from human observation. The Ben Hago schools increasingly became the mainstream of the explanation of the uncertainty principle.
If this is true, then our world is naturally uncertain. And this uncertainty is precisely because of the participation of human consciousness. Man's consciousness wants to know the world precisely, but it is precisely because of the participation of man's consciousness that the world becomes uncertain. How interesting that is.
