Imagine the first rays of sunlight streaming through your curtain, casting a perfect Fibonacci spiral on the floor; the twinkling stars in the night sky following the elegant proportions of the golden ratio; each unique snowflake falling as a masterpiece of geometry. Mathematics is nature's most romantic poem.

In this book, we will take a stroll together through the garden of mathematics. You will discover that prime numbers are like solitary stars in the night sky, maintaining a mysterious distance from each other; infinity is like a never-ending adventure, inviting us to explore the unknown; and topology is like a magician's handkerchief, magically connecting a coffee cup and a donut.

Open it, and a child will measure the universe with geometry under the starry sky, cut pizza slices with fractions in the kitchen, and exclaim, "Math is this cool!"

Recommended by Alibaba data scientist Yuan Guanghao, this book presents the history of mathematics, formulas, geometry, and puzzles through large illustrations and engaging cartoons. It integrates interdisciplinary knowledge from art and biology, turning history, art, and biology into a playground of mathematics. With one book, it ignites the reader's passion for learning and provides an easy entry into the world of math.

In this book, readers can see the world from the shoulders of giants and unlock the secrets of mathematics – understanding the development of mathematical history and witnessing the birth of formulas, theorems and corollaries.
