E=mc2

Albert Einstein's E=mc2 is the most famous equation in history. It has been printed on t-shirts, featured in films, and used as a shorthand for scientific genius. Yet, its profound meaning is often obscured by its simplicity. The equation is not merely a recipe for a nuclear bomb, nor is it an abstract piece of mathematics.

Kepler’s Laws of Planetary Motion — Simplified

An ellipse is like a stretched circle. Imagine a circle squeezed sideways — that’s an ellipse. An ellipse has two foci. The Sun sits at one, and the other is empty space. Planets are not moving in perfect circles; their distance to the Sun changes as they orbit.

Wave Function (Ψ)

The wave function is a mathematical function — a set of numbers you can calculate — that tells us everything possible about a quantum system. Here’s the key: Ψ itself doesn’t directly give us a physical answer. Instead, when you take its absolute square (|Ψ|²), you get the probability of finding the particle at a particular place or in a particular state.
