These 17 Equations Changed The World

@science

There is math in every nook and cranny, folks. It fashions the world in more than one methods. Ian Stewart is a mathematician who published a book called 17 Equations That Changed The World. Let us educate you on how all of these equations fashioned the history of humans and math altogether.

The Pythagorean Theorem

The understanding of geometry is buoyed by this particular theorem. The relationship between each side of a right triangle is explained here before the length of each short side is squared and added and this equals the square of the length of the longest side.

Logarithms

These are opposites of what we know as exponential functions. Logarithms for specific bases demonstrate which power is needed to lift the base to arrive at a number. Prior to the invention of computers this used to be the way to multiply large numbers in no time which not only helped the field of physics, but also engineering and astronomy.

Calculus

This is a measure of the rate at which quantities change. Many fields of science deal with the logic of change in things along with the derivative. These aspects are key to fields such as science as well as mathematics.

Law of gravity

Law of gravitation highlights force of gravity between a couple of objects as universal constant G, mass of a couple of objects and distance between a couple of objects. The theory of gravity proposed by Newton stayed intact for 200 years before Einstein presented his theory of general relativity.

Square root of -1

The square root of -1 is written as ‘I’. It results in complex numbers. There is a great amount of intersection between calculus and complex numbers. As a result, complex numbers are fundamental to electronics as well as signal processing.

Euler’s Polyhedra Formula

According to this formula, once the faces and vertices are added and the edges subtracted, the result is always 2. This rule holds regardless of the number of faces that the polyhedron contains. The observation by Euler is a primary example of topological invariant – property or number shared by a group of shapes which mimic the same postulates.

Normal distribution

The usual curve that we know is utilized in fields of biology, physics as well as social sciences. The curve demonstrates the behaviour of big groups of independent procedures.

Wave equation

This differential equation describes the way properties varies as time wears on in shape of the derivative of the properties. It describes the behaviour of waves, be it ripples in a pond or a vibrating string of a guitar.

Fourier Transform

This is important for understanding complex wave structures such as human speech. It lets people break messy wave functions in groups of numbers of simple waves. This significantly simplifies analysis. Infact, it is fundamental to the concept of data compression and signal processing.

Navier-Stokes Equations

This is also a differential equation which describes how flowing fluids behave. It could be air flow from the wing of an airplane or water moving along the pipe. These equations let computers simulate fluid motion.
