At the beginning of the nineteenth century, there was a famous French probabilist and physicist named Laplace.

He, ah, from the bottom of his heart that: fate, there is!

Laplace also told us that "the future of the world is determined entirely by its past, and it is possible to predict the future by knowing mathematical information about the state of the world at any one time.

The saying is: everything knows the reason, you can know the result, everything is arranged.

Laplace was afraid that everyone would not believe him, but also specially opened a "plug-in," in 1812 in his book "Probability Theory of Analysis" compiled a mythical animal-Laplace beast.

He said that there was an intelligent and invincible divine beast in this world, called Laplace Beast, which was omnipotent and omniscient.

Usually, Laplace Beast only needs to blink at home to learn the exact position and momentum of every atom in the universe, and then use Newton's "Great God" formula to calculate the past and future of the universe.

Whenever Laplace had time, he took his Laplace beast around the streets, advertising its "fortune-telling" skills.

Folks look, wow, so cool, so like it!

They pampered Laplace as a treasure and gave it a series of pet names-determinism, historical determinism, scientific determinism, scientific determinism...

Moreover, whether it was ordinary people or senior scientists at that time, the young and old of the nearby villages all recognized this logic.

They believe that the world runs as strictly and steadily as a clock, with rules and regulations, and that we can master the rules of the clock by taking it apart and finding out the position of all its parts.

In other words, as long as humans know enough information, they can predict everything, because everything is determined by causality.

Just like the cosmic process, it can be expressed in a simple mathematical equation. The current state of the universe is the cause of what will happen next.

Later, people called this theory "mechanical theory," or Laplace determinism. The biggest fan of mechanics is the famous scientist Einstein.

Einstein once wrote to Bohr: "You believe in a God who rolls dice, but I believe in perfect laws and order. "

Fans sought after, celebrities supported, this Laplace beast can be awe-inspiring, at that time very proud!

It crossed its legs for more than a hundred years.

But the Laplacian did not know that the cat of quantum mechanics was coming and that its momentum was about to be suppressed.

In 1927, Heisenberg proposed the "uncertainty theorem," also known as the "uncertainty theorem."

The uncertainty theorem, what is it?

In short, because of wave-particle duality, the momentum and position of microscopic particles cannot be measured simultaneously.

It was later discovered that in addition to the limitations of the particle itself, the limitations of technology also affect the results of the measurement.

For example, if humans want to measure microscopic particles, the only way is to observe; if they want to observe, they have to use tools, and this tool is electromagnetic waves.

Moreover, the shorter the wavelength of this electromagnetic wave, the better, because the shorter the wavelength, the more accurate the results would be.

However, the shorter the wavelength of electromagnetic waves, the higher the frequency.

The higher the frequency, the greater the momentum, and the greater the disturbance to the object.

Therefore, the more accurate the position of your particle is, the more inaccurate the momentum will be.

To put it bluntly, microscopic particles, if you don't provoke them, they will behave obediently. If you provoke them, they will be excited!

It was just like Schrodinger's cat. If you didn't interfere, everything would be fine.

Curiosity kills the cat when you interfere.

Thus Laplace's word-of-mouth crumbled: since the momentum and position of microscopic particles could not be measured simultaneously, Laplace could not be omniscient!

Laplace's fans came to their senses: Laplace, you liar!

Or perhaps there is no Laplace at all, but people prefer to believe that Laplace exists.

But in fact, let alone in this world, the Laplace Beast was already untenable in theory, because it could not even pass the most basic logic.

Contemporary chaos science rejects the idea of Laplace determinism.

So you see, Laplace is a fairy tale.

Fairy tales are all lies.

Many years after the Laplace beast stumbled, Hawking, another famous scientist, echoed Einstein's words to Bohr in A Brief History of Time.

He said,"God not only rolls dice, but rolls them out of sight.

This is exactly the answer to an old Chinese proverb-people are not as good as God.
