Amazing Uses of Calculus in Real Life
The universe is constantly in motion, stars, planets, and galaxies are constantly changing. Elements, particles and subatomic matter bodily matter are not static either. Before the invention of calculus, Mathematics was static. Calculus is a branch of math that calculates how matter, particles and heavenly bodies actually move. Calculus is used to calculate the rate of change in real-time.
In the latter part of the 17th century, two scientists Sir Isaac Newton and Gottfried Leibniz. Leibniz developed mathematical notations used today (+, -, x, and ÷) Isaac Newton developed calculus and applied it directly to calculating physical systems.
With these tools, Mathematicians could calculate slopes, curvatures, rate of change and motion. It enabled them to understand motion and the dynamics of a changing universe and the elements in the world and the orbit of galactic planets.
‘Calculus’ singular or ‘Calculi’ plural – is a Latin word which means ‘small pebble’ – small stones used for counting in the abacus by the Romans. It was used for the counting of infinitely small numbers. Calculus is math in motion. It’s the calculation of change used to help describe the dynamic nature of our world.
It has two branches, differential calculus which calculates the behavior and rate at which quantities change e.g. distance changes over time. It involves the concept of derivatives of functions. The second branch is integration calculus; this is the reverse process of differentiation. It helps describe, for example, the volume of a 3d object with a curved boundary and many other similar applications. Differentiation is the opposite or the inverse of integration.
Integration breaks the region apart into thin unlimited vertical rectangles of equal width until they become a Limit. A process which allows mathematicians to calculate volumes, area, and precision. If you differentiate a function and then integrate it, it will always take you back to where you started.
Calculus is used in lots of fields, physics, engineering, medicine, economics, biology, engineering, space exploration, statistics, pharmacology and many more. Without calculus architects and engineers couldn’t build safe structures.
It is used to calculate changes in quantities and systems. Calculus helps to analyze, find optimal solutions and predict the future. Calculus has given us incredible power over the world because of its ability to model and control systems.
