Key Contents

What is the true nature of Newtonian mechanics, which still plays its role today? Why are magnets magnetic? What are the five elements? What is entropy? In what ways is Mendeleev, the creator of the periodic table, considered ahead of his time? What does "general" mean in the theory of general relativity? Is time an illusion? Why is the sky blue and the sun yellow? Why do planes landing at night turn off their cabin lights 15 minutes before landing?

This book is about thinking about these basic questions, but the true nature of which we didn't know, and finding out the reasons together.
Dedicated to all non-scientific minds, this book explains basic scientific principles and theories in an easy-to-understand manner.
The author explains scientific principles in an easy-to-understand manner and organizes terminology to help readers understand science as a whole.
Starting from the basics, to the skeleton of science that makes up today's world, to the things we commonly see around us, to the world that we cannot see or intuitively understand, it covers everything about science, but it unfolds the stories in a fun and entertaining way so that readers do not get bored.


89 Hilarious Stories About Science
Great scientists and their even more great and special lives and research

In “Matter,” we learn about the atoms that make up our world.
Beginning with the opposition to Aristotle's five elements, the story unfolds on a grand journey to the actual discovery of atoms and the remarkable figures ahead of their time.
Next comes the story of “light,” which we think we know, but in fact we don’t know much about, and which is still a subject of controversy.
The optical illusions that occur when light from the sun reaches us confuse us.
It covers all the stories about “light,” from why the sky is blue, why the sun is yellow, and even why pink isn’t really a color.

In “Electromagnetism,” there is a story about magnets and lightning.
Since ancient times, people have been deeply interested in the phenomenon of static electricity being generated when rubbing amber (not the edible amber, but the gem amber).
And I also wondered about the lightning that split the sky and tore the earth apart.
The amazing stories of Ampere, Gauss, Faraday, and Maxwell, who appeared in the course of history and discovered the relationship between magnetism and electricity, are introduced.
Turning our eyes to the sky, “Solar System” introduces all the planets that make up the solar system and the history of their discovery, and explains why “Pluto” was removed from the planets.
The stories of each planet can be said to be like the history of humanity's expansion of vision.
The author then dedicates a chapter to Guillaume Le Gentil, whose life was marked by failure.
His story shows that before a single successful scientist emerges, there are thousands of people who have failed and sacrificed themselves for the advancement of science.

In “Classical Mechanics” we learn about the true nature of Newtonian mechanics.
It tells the story of Archimedes, Galileo, Giordano Bruno, a pioneer who went against the times but was sacrificed by the Inquisition, and Isaac Newton, the great scientist who discovered the laws that govern the world we live in.
Although it is unlikely that Newton was actually hit by a falling apple, and although he hated Robert Hooke and tried to keep him from getting his due, the fact remains that Newton put forward scientific theories that people believed to be “truth” for the next 200 years.

“Life” explains the amazing things our brain does and uncovers the secrets of the wondrous human body.
In “thermodynamics,” we talk about the difference between temperature and heat, and steam engines.
The story of Francis Bacon, who opened a new way to approach science through experience and observation, is also introduced.

“Special Theory of Relativity” explains the theory of the great scientist Einstein, which changed our perception of time and space.
“General relativity” reshapes our thinking about gravity.
However, these two chapters are not theoretical analyses and interpretations of the theory of relativity, but rather interesting stories that show in what ways Einstein was a genius and in what ways his theories completely overturned the existing way of thinking about the world.
