A wondrous scientific journey that unlocks the secrets of evolution, the universe, and all things.
The minimum scientific knowledge required by adults today
A much deeper and broader science story, now including the 'evolution of life'!

The secrets and beauty of life's evolution are revealed by evolutionary biologist Lee Dae-han.
Astronomer Ji Woong-bae clearly explains the mysteries and romance of the universe.
Physicist Kim Beom-jun's scientific methodology for unraveling the world's problems.
+ Jeong Yeong-jin's wit and sense of reality!

The popular series "See Science" from the YouTube channel "BODA" with 2.3 million subscribers has returned with its third book.
Those who conveyed the charm of science through YouTube videos lowered the barrier to science for general readers through their first book, and if their second book presented deep biological insights, this time, "Seeing Science 3" contains an even broader range of topics and diverse stories.
This book covers life and evolution, the secrets of the universe, and even scientific curiosities that we often overlook in our daily lives.
For example, it allows us to freely let our scientific imagination run wild with unconventional questions like, “Is it true that monkeys have now entered the Paleolithic Age?”, “Why didn’t dinosaurs achieve civilization like we did?”, and “Can we restore ancient creatures from the ice?”
The story, which starts with a sometimes absurd and sometimes serious question, naturally makes you nod your head as it leads to scientific evidence and witty explanations.

The greatest appeal of 『Science in the Eyes 3』 is that it addresses a topic that was once perceived as difficult in a way that is accessible to readers.
From classic questions like “Is glass a solid or a liquid?” to intriguing stories like “What happens when light collides with light?” and “Did the elements in our bodies come from stars?”, even those who have been shunned by science will find it hard to resist.
In particular, YouTube videos provide detailed explanations and interesting behind-the-scenes stories that were difficult to include due to time constraints, making them a welcome gift for readers interested in science.

As we move between playful questions and serious answers, we come to realize that science is no longer a difficult subject, but rather a delightful tool that allows us to see the world in a new way.
The moment you open the first page, you'll be immersed in the scientists' stories, and by the time you close the last, you'll have gained a new perspective and deeper knowledge about the world.
"Science 3" once again satisfies our curiosity and provides the joy of building scientific literacy.
Let's open the book and enter the world of science.

About 2.5 billion years ago, long before the five major extinctions, Earth experienced a great oxygenation event, a sudden increase in oxygen in the atmosphere.
After the Earth was first formed, its atmosphere was mainly composed of carbon dioxide, methane, and nitrogen, just like other planets in the solar system.
Over a long period of time, organisms that produce oxygen through photosynthesis evolved, and highly reactive oxygen combined with other substances to exist in the ocean in the form of sulfate, M21SO4, etc.
As the amount of oxygen in the ocean gradually increased, at some point the concentration of oxygen in the atmosphere also rose rapidly, a phenomenon called hyperoxygenation.

Although the theory of spontaneous generation was proven to be correct, a bigger question arose.
So where did the first life form in Earth's history, the origin of all life, come from?
Even Charles Darwin, known as the father of evolution, could not give a clear answer to this question.
Although he did not write about this in his book, "On the Origin of Species," he did say in a letter to a friend that he could imagine that life arose "in a warm little pond, in the presence of ammonia, phosphate, light, heat, and electricity."
Now, following the famous Miller-Urey experiment of 1953, many scientists generally agree that the Earth's primordial atmosphere and climate conditions could have provided a clue to the origin of life by allowing inorganic substances to chemically synthesize organic compounds such as amino acids.

Before the discovery of penicillin, even minor injuries, such as a fall or a thorn prick, could be fatal.
There was nothing we could do if bacteria infected the wound.
Extreme treatments included cutting out or removing the affected area, but there were many cases where infection occurred again during the process.
Considering the long history of mankind, it is not that long ago that we learned that the cause of these infections is bacteria, or germs.
In 1855, Louis Pasteur was asked by French winemakers to find out why their wine kept turning sour. While studying spoiled wine samples under a microscope, he discovered that bacteria were the culprit.
And he developed the pasteurization method, which could kill bacteria without boiling.
This is why Pasteur's name often appears in the milk and yogurt we eat.

As soon as I hear the question, the first thing that comes to mind is The Matrix.
It was a movie released in 1999, so it was 25 years ago, when I was very young.
The scene where the main character Keanu Reeves leans back to dodge countless flying bullets is very famous.
The film features a setup where machines control human consciousness by inserting a type of electrode into the back of the human head.
Even putting aside the fact that the scene depicting this was visually impressive, I remember being quite shocked by the idea that all of our consciousness and senses are the result of neural activity occurring in the brain and can be controlled by machines.
Moreover, looking at the artificial intelligence-related technology that seems to be developing at the speed of light these days, it was a scene that showed an absurd imagination based on the knowledge of people at the time, but now there are scholars who worry that the future depicted in this movie may become a reality for humanity.

When you think of a pizza-making scene on TV, you see a chef quickly turning a round ball of dough with both hands.
Then you will have a flat dough.
The gas clouds that make up celestial bodies such as stars are also lumps of cosmic dust that have gathered in a disorderly manner under the influence of gravity, like dough.
And inside this gas cloud, gravity continues to act, and the rotational motion continues, and as the speed increases, the center contracts up and down like spinning pizza dough, and the outer part expands outward due to centrifugal force, gradually forming a disk shape.
As the gas and dust within the disk continue to clump together, they eventually form stars and planets.
Not only the planets in our solar system, but also the planets in other universes that orbit their stars, are positioned almost on the same plane through this process.

If you are interested in space, you may have heard of it at least once.
It's a conspiracy theory-like claim that there's another star lurking in the outskirts of our solar system, orbiting the Sun in a very elongated, elliptical orbit.
It is called the 'Nemesis Star' after the goddess of revenge in Greek mythology.
It is said that this Nemesis periodically approaches the inner solar system and disrupts the orbits of asteroids orbiting the Sun and Earth, causing a huge number of meteorites to crash into Earth, causing a catastrophic extinction of life.
In common parlance, it is a typical 'bait'.

Perhaps the reason the Soviet Union made such a fuss about this phenomenon was that the Earth could be viewed as a three-dimensional object that rotates, and since the Earth's surface is not a perfect sphere, with high mountains and deep oceans, phenomena like the tennis racket theorem could occur.
It seems that there was concern that if the Earth's axis of rotation were to suddenly shift, a disaster on a scale that could lead to the destruction of humanity could occur.
So, it seems that for a long time, the country has been conducting research by attaching various structures to a sphere similar to the Earth or changing its shape.
But in the end, since no problems were found, they would have released the secret and made it public.

However, the interesting motive in the novel "Dividing by Zero" is that a mathematician proves through the logical process of mathematics that division by zero is possible.
Then, as in the proof above, it leads to the conclusion that all numbers are equal to other numbers.
There are two cups of water in front of us now, and it is possible to ask, 'Can we really see these as two now?'
The content of the novel develops in an interesting way, and the reason I like this novelist is because he poses provocative questions in the fields of science and mathematics, such as, 'What if the knowledge we know is not true?'
