The Birth of Graph Theory
In 1736, a mathematician in the city of Königsberg was asked a curious question. The city was divided by a river and connected by seven bridges. Residents amused themselves by attempting a simple walk: cross every bridge exactly once and return home without repeating any. Many tried. None succeeded. The puzzle eventually reached a Swiss…

Combinatorics: The Mathematics of Choice
Every day feels full of decisions. What to say. What to prioritise. Which path to take. We experience choice as something psychological, even emotional. A matter of preference, intuition, or circumstance. Mathematics sees something different. It sees structure. Long before probability theory, mathematicians confronted a deceptively simple question. This occurred long before algorithms and artificial…

What Actually Holds Systems Together
At first glance, a set is a lonely thing. It is a collection of elements, neatly grouped, carefully defined, and entirely self-contained. A set of numbers. A set of people. A set of possible outcomes. Each element exists, but nothing happens yet. There is no movement, no interaction, no consequence. Just membership. On their own,…

The Architecture of If-Then
In 1847, a British mathematician named George Boole published a book. He made an audacious claim: human thought could be reduced to algebra. Not metaphorically, literally. The messy, intuitive, seemingly ineffable process of reasoning could be expressed as equations, manipulated like numbers, proven like geometry. His contemporaries thought he was mad. Thought, after all, is…

The mathematics that runs your life
In 1936, a young British mathematician named Alan Turing wrote a paper that most people ignored. It wasn’t about building computers; those didn’t exist yet. It was about something stranger: whether certain mathematical questions could ever be answered by following a set of mechanical steps. The paper was theoretical, abstract, obscure. But buried in it…

The mathematics of everything you can touch
Here’s a question that sounds simple but isn’t: What’s the difference between water and coins? Water flows. You can pour it, divide it infinitely, and measure it in fractions. There’s no “smallest unit” of water that matters; you can always split it further. Half a cup, a quarter cup, a molecule, an atom. Coins don’t…

The unlikely peace treaty
Here’s a question that doesn’t get asked often enough: What do nuclear physicists and subsistence farmers in Bangladesh have in common? The answer, as of November 10, 2001, is a holiday. World Science Day for Peace and Development. And if that sounds like bureaucratic window dressing, another UNESCO initiative designed to make us feel good…

How linear algebra powers AI, physics, and cryptography
When most people hear the term linear algebra, they imagine rows of numbers in matrices or tedious exercises with vectors. Yet, far from being an isolated branch of mathematics, linear algebra is the hidden architecture of modern science and technology. It is the language that allows people to describe relationships, transformations, and patterns in systems…

Montreal Protocol saved the Ozone layer
Science Days: 16th of September On the 16th of September, the world commemorates the International Day for the Preservation of the Ozone Layer, a day dedicated to raising awareness about the importance of the ozone layer and the global efforts to protect it. Established by the United Nations in 1994, this day marks the signing…

Understanding eigenvectors and eigenvalues
At first glance, words like eigenvector and eigenvalue look like they belong in some obscure math museum. But behind the heavy names are surprisingly simple ideas. They’re not about memorising formulas. They’re about uncovering the hidden rules that shape change: in geometry, in data, and even across the internet.
