Article | Have Our Problems Changed as Tools Become More Powerful?
As tools become more capable, we can do more and more things—but does that mean problems become easier to solve? From calculators and drawing tools to artificial intelligence, this article explores how growing capabilities can change the way we understand problems, as well as the relationship between functionality, experience, and different abilities. As old constraints disappear, the factors that truly shape an outcome may change too. Perhaps we need not only more powerful tools, but also to reconsider the problems we want to solve.
Article | Is Mathematics the Language with Which We Converse with God?
If mathematics is a language, then who exactly is it communicating with? This article starts with mathematical notation and explores the relationship between mathematics, human cognition, and the objective world, while proposing an open-ended hypothesis: perhaps mathematics is the language through which humans formally communicate with the world.
Article | What Is Modular Arithmetic? Why Can 17 and 5 Be “Equal”?
Modular arithmetic is a mathematical system that allows us to understand integers through the idea of “cycles.” Why can 17, which clearly is not equal to 5, be written as 17 ≡ 5 (mod 12)? Starting with clocks and remainders, this article explores congruence, residue classes, and the mathematical ideas behind the symbol “≡”, and shows how a seemingly simple symbol can open the door to a whole new world of modern mathematics.
Article｜Newton’s Method of Fluxions: What Did Calculus Look Like Before Leibniz’s Notation?
Before Leibniz’s dx/dy and integral notation became the standard language of calculus, Newton used a very different way to describe change. This approach, known as the method of fluxions, raises a fascinating question: what did it actually look like? Let’s return to the birth of calculus and see how mathematicians tried to capture change in the world before they had the symbolic language we use today.
Article | Why Did Ancient Egyptians Guess the Answer First? — The Idea Behind the Method of False Position
Four thousand years ago, the ancient Egyptians had neither unknowns nor an equals sign, yet they were able to solve problems that would require equations today. They first guessed a number that was easy to work with, then repeatedly adjusted it using proportions. This was the method later known as the Method of False Position. More intriguingly, this idea of gradually approaching an answer from an initial starting point has a connection to modern numerical computation that spans thousands of years. Starting with an ancient Egyptian mathematical problem, this article explores the mathematical thinking behind the Method of False Position, and how humanity gradually moved from working with specific numbers toward studying relationships between quantities—the foundation of modern algebra.
Article | What Is a Unit Fraction? Why Didn't the Ancient Egyptians Use Ordinary Fractions?
Why did the ancient Egyptians rarely use the ordinary fractions we take for granted today? Instead, they expressed almost every fraction as a sum of unit fractions—a seemingly cumbersome system that shaped Egyptian mathematics for thousands of years. This article explores what unit fractions are, why they became the foundation of Egyptian mathematics, the way of thinking behind them, and why they were eventually replaced by the modern fraction notation we use today.
Article | What Does a New Tool Really Change?
AI led me to a question that had little to do with technology itself: when a new tool enters our lives, what does it really change?
Video | The Origins of + − × and ÷
Journey from ancient Egypt to Leibniz and uncover the remarkable story of the four basic arithmetic symbols that reshaped mathematics.
