Vaccines: everyone has had them, but not everyone understands them!
First, let's understand what vaccines are. How many types of vaccines are there? A vaccine is a biological product made from various pathogenic microorganisms (bacteria, viruses, tumor cells, etc.). Vaccinations are administered. In addition, the use of bacteria or spirochetes to make a vaccine can also be called a vaccine.

How did earthworms become the favorite food of fish, two species that rarely meet in a lifetime?
Earthworms are one of the most basic creatures in the world and live in the soil all year round due to their habits, except for weather factors such as heavy rains. However, due to the life cycle of earthworms, from which many places are born, it can be said that earthworms live in the soil almost all their lives.

Haunted beds: a nightmare that hits multiple human weaknesses! So you get scared!
I'm sure many people have had the experience of waking up suddenly, only to find that they can't move or even make a sound, but their sense of sight and hearing have become more acute than usual. At this point fear ensues, perhaps because of the visual or auditory senses, but more likely psychologically. This is called ghost pressure, also known as nightmares.

Entropy: the thermodynamic unit that speaks to the rules of nature, so against the rules of nature you can hardly discipline yourself!
Firstly, an introduction to Clausius who proposed the unit of entropy. Clausius, whose full name was Rudolf Julius Emanuel Clausius, was a German physicist and mathematician who was one of the main founders of thermodynamics. He restated the Nicolas Carnot law (Carnot cycle) and pushed the theory of heat to a more realistic and sound basis. The basic concept of the second law of thermodynamics was later clearly stated and the concept of entropy was introduced.

Scientists calculate that there are 100,000 extraterrestrial civilizations in the galaxy, but it is not very realistic to reach humans
It has been 13.8 billion years since the universe was born. During these 13.8 billion years, the universe has expanded faster than the speed of light, and its diameter has exceeded 93 billion light-years (93 billion light years, which is an observable space. As for the observable distance, it is still unknown how big the outer part of the universe is).

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.

Electric eels that are hard on others and even harder on themselves, dare to electrocute themselves into baked fish at the drop of a hat
In the 18th century, electricity was gradually tamed by humans, who learned to store and release it. But at first, people were curious about electricity and wanted to know what it felt like when it passed through the body, that is, people wanted to try the taste of electric shock.

Schrödinger's cat: the most famous cat in science, explaining quantum mechanics with the power of a cat!
Schrödinger's cat is the most famous in science because he explained the baffling quantum mechanics to everyone through his own life and death. Let's start with what Schrödinger's cat is and how it explains quantum mechanics for us.

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.

Quantum mechanics: what exactly does quantum entanglement entangle? How is it entangled? A simple explanation for you!
Quantum mechanics is the most important science research today, and if we could fully understand it and apply it to our lives. then our world would change dramatically. However, quantum mechanics is still only on the way for scientists to study. Quantum mechanics is not the same as common sense we have in Okawa. After all, it takes a lot of effort to understand what quantum mechanics is all about, so it is still a long way to go.

Is the speed of light unsurpassable and does the FTL phenomenon really exist?
When it comes to the speed of light, we should first think of Albert Einstein and his theory of relativity, one of the greatest achievements of physics in the early 20th century. Relativity fundamentally changed the old concepts of time, space, and motion and established a new space-time.

Boltzmann brains and brains in tanks: do we live in reality or fantasy?
Boltzmann's brain and Schrödinger's cat are similar concepts, both belonging to the imagination of scientists. Schrödinger's cat is based on the assumption of quantum mechanics, and Boltzmann's brain is based on the assumption of entropy. My previous article just introduced what entropy is and explained how entropy increases (for those readers who do not understand entropy, please go through my previous article first to get a feel for it and to lay the foundation for understanding this article). Boltzmann's brain is a point of knowledge that unfolds in the context of entropy.
