9 Physics Facts That Actually Explain How Reality Works
Physics is treated as a subject full of formulas that nobody needs after school. In practice, it explains why GPS works, why airplanes stay up, and why the sky looks the way it does at night.

Mathematics has a reputation for being dry — rows of formulas, endless equations, homework nobody wanted to finish. But behind the symbols lies one of the strangest and most creative fields humans have ever explored. From infinite primes to shapes that defy intuition, math is full of surprises that feel closer to magic than logic.
Physicians developed the ketogenic approach in the 1920s to treat epilepsy in children. Russell Wilder at Mayo Clinic coined the term in 1921 after observing that fasting reduced seizures. The diet mimicked starvation effects by limiting carbohydrates, forcing the body to burn fat. Before modern medication,s it controlled seizures in many cases.
Adolphe Quetelet developed the BMI formula in the 1830s as a statistical tool for average men in populations. A Belgian astronomer and mathematician created it without medical intent. Ancel Keys renamed it Body Mass Index in 1972, promoting individual use. Originally called the Quetelet Index, it measured social physics rather than health.
Geometry began in practical needs. Egyptians surveyed land after Nile floods using ropes with knots, creating early right-angle tools around 3000 BC. The Greeks transformed these methods into deductive science. Euclid compiled the Elements around 300 BC, organizing 465 propositions from basic axioms. This work defined points, lines, and planes without coordinates, influencing mathematics for centuries.
