Скачать или смотреть Polygon Secrets: Liu Hui’s Ancient Formula for Pi

What if I told you that over 1,700 years ago, a Chinese mathematician calculated Pi (π) almost as accurately as we know it today—without calculators, computers, or even modern formulas?
This is the story of Liu Hui (劉徽), one of the greatest yet forgotten minds in the history of mathematics.
In the 3rd century AD, Liu Hui improved the famous Chinese text The Nine Chapters on the Mathematical Art and introduced a brilliant polygon method to approximate Pi. By inscribing a 192-sided polygon inside a circle, he achieved a value of Pi that stunned the world—centuries before Europe even caught up.
📌 In this video, you’ll discover:
How Liu Hui calculated Pi using pure geometry.
Why his method was centuries ahead of its time.
How his work laid the foundation for later mathematicians, including Archimedes and modern calculus.
Mathematics isn’t just numbers—it’s a story of human genius across cultures and centuries. And Liu Hui’s work proves that the pursuit of Pi is truly infinite.
