11 Equations That Changed The World


In Brief

The pulse of the earth is mathematics.The brightest minds in history have used mathematics to lay the foundation for how we measure and understand our universe. Time and time again, we have proved that it only takes one simple formula to alter the course of humanity. Here are 11 equations that did just that.

1. Theory of Relativity, Mass–Energy Equivalence

Before Einstein came along, classic physicists thought mass and energy were separate things. With the now-famous E = MC2 equation, Einstein showed that mass and energy are interchangeable concepts, and relate to each other through the square of the speed of light. There are two categories of relativity: special relativity, and general relativity. In special relativity, Einstein also showed that the speed of light is the absolute fastest speed any object can travel in the universe, precisely at 299,792,458 meters per second. In general relativity, Einstein postured that mass not only creates a gravitational field around them, they actually bend the space time around it. The more massive the object, the greater the bend. In fact, some objects such as black holes are so massive that time actually slows down around it.
