Pomegranate revisited: everything you've experienced could happen again in the future!
We've talked about entropy before, extending Boltzmann's brain in the context of entropy. (I haven't read it yet, so for those interested, feel free to read my previous post.) The reproduction of Poincaré is also related to entropy. It may seem to conflict with the principle of entropy increase, but it does not.

To save money, U.S. astronauts in space, grabbing a 4-ton satellite with their bare hands for repairs
In one of the most thrilling emergency repair missions in the history of space flight, three astronauts left the cabin and decided to give it a try by grabbing the 4-ton satellite, which was moving and spinning at high speed, with their bare hands. If there is a slight failure in this process, leaving the astronauts only a short 20 seconds to save themselves. It can be said that life is at stake, life, and death only in a moment.

Cosmic holography: the world as you perceive it is only a projection, every atom is a universe!
What is the universe anyway? What is it like? According to our current knowledge, simply put, there are countless luminous stars and nebulae, and countless planets in complete darkness. We don't know the edge, the size, or even what the universe is. We are just a drop in the ocean in this vast universe, small and insignificant. Yet we are tirelessly and persistently pursuing the truth of the universe.

The Zeno Tortoise: Can man never catch up with the tortoise? A dialectic of the past, cracked by modern science!
In our last article, we talked about a cat, Schrödinger's cat, but this cat has confused many people. Other animals should be difficult for such people to get along with, such as the tortoise we are talking about today. This tortoise is a figment of Zeno's imagination and has the advantage of being ahead of Achilles, who always runs well.

The Laplace Demon: Knowing everything about the universe, knowing the past and the future, and finally being put to an end by quantum mechanics!
Jokes are circulating on the internet about the four great beasts of physics. They are Schrödinger's cat, Zeno's turtle, Maxwell's demon, and Laplace's demon. Schrödinger's cat I talked to you about a long time ago. The first two articles talked about the Zeno Turtle and the Maxwell Demon. Today's article on the Laplace Demon is the end of the four great beasts.

Superbugs: an invisible battle lurking around everyone, pay attention!
Three years have passed since the outbreak of the new crown pneumonia outbreak in late 2019. Thanks to our effective measures, the outbreak has been largely under control since the middle of the year. The country has now largely returned to normal functioning. However, this is not the case abroad. The epidemic is raging in most countries and the number of patients is on the rise.
