The Universe

The universe is vast. The origins of life and substances are hidden in the universe. "What are we? Where do we come from? Where are we going?" Let's look into the infinite mystery of the universe through the lens of science.

A Magic Square

A Magic Square is a mysterious puzzle in which numbers are inserted into boxes so that rows, columns, and diagonals always have the same sum. They are called Order-3, Order-4, Order-5, and so on, depending on the number of boxes in each row or column.

The Earth

The Earth gave birth to the firm land and ocean, and has produced new life since before the dawn of history. Massive amounts of energy are still contained deep inside, beating like the heart of a living creature. Let's learn about the true face of the "Turbulent Earth."

Cavaliere's principle

Cavaliere was a student of the noted 17th-century Italian mathematician Galileo Galilei. Cavaliere's principle is that "Area and volume do not change even if the position changes." Let's use Cavaliere's principle to try some area-related problems.


Everything in the world is made up of substances. The creation of the universe, the birth of the Earth, and our lives and nature came into existence as a result. Let's think about how our world is interlinked through "substances."

Sei Shonagon's Puzzle

"Sei Shonagon's Puzzle" starts with a square that has been broken up into seven pieces. Some say that this puzzle was the origin of the Tangram. Using these seven pieces, you can create many shapes, including animals and everyday objects.


How did simple substances evolve into life? When we reflect on the path of evolution from ancient times to the present, Our eyes may be opened to the deep connection between life and the global environment.

Unicursal Puzzles

The nature of unicursal figures was first described by the 18th-century mathematician Leonhard Euler. The people of Konigsberg were trying to figure out it was possible to walk a route that crosses each of the seven bridges only once. Euler was able to find the answer easily.

The Human Body

Each of us was born through a miraculous mechanism. From valuable images of the inside of human body, let's learn about the roles played by various body parts that sustain life, and open a door to the quest for what it means to be alive.

Pythagorean Theory

Under the banner of "The Harmony and Beauty of the Universe," the Pythagorean Order left its mark in the fields of mathematics, music, and astronomy. It is most famous for proving the theory of the right-angled triangle. The theory of the right-angled triangle is also called the "Pythagorean Theory."


The world of human beings is only a small part of the Earth. Discover the Earth's hidden world of animals that are invisible and inaudible to humans. And let's think about the reasons behind the bizarre shapes and unique lives of animals.

Pencil Rotation Method

Use the "Pencil Rotation Method" to measure the angle that the pencil has moved. The more the pencil moves, the larger the angle. The important thing is that the angle doesn't change if it is "translated" to a different position.


Plants have a mechanism of life that is totally different from animals. From ancient times, this mechanism has had a large impact on the global environment and the evolution of animals. Let's learn about the unique roles and characteristics of plants.


"Komachi-zan" is a math puzzle where you arrange the digits 1-9 and mathematical symbols like +, -, x, and ÷ so that the outcome is 100. This puzzle was named after Komachi Ono, a beautiful woman poet from Japanese history, because it expresses the balance and beauty of numbers.

Environment & Energy

The natural environment and human activities interact in diverse ways. What has happened to the balance of the two? Did massive consumption of energy and resources cause a new crisis? As a global citizen, let's think about environmental & energy problems.


The German mathematician Felix Christian Klein found that it is possible to determine values for complex shapes by changing them into simpler shapes.


By looking at the origins and the cutting edge of tools and technologies, let's think about how we are trying to face our future in the universe, on the Earth, in nature and in life. And imagine where the evolution of our species is going.

Nets of Polyhedra

If you unfold the box that a cake or pastries came in, you get all kinds of shapes. This is an "unfolded solid." Let's try some puzzles using unfolded solids.

Sports Science

This section explains the correct way to use your body, the secrets of the herculean skills of athletes, and various support mechanisms for sports with a scientific perspective. Let's try a quiz and practical skills.

Toilet Paper and String

When you carry lots of things at once, you want to use as little space as possible. When toilet paper is carried to the South Pole, it gets squashed, and then it returns to its original shape later. Now, try to find a way to make the string as short as possible when carrying the toilet paper.
