Calculus is a field of mathematics that studies functions, limits, integrals, derivatives, and infinite series. It is a fundamental concept in modern science, engineering, and economics. It was a field of study developed independently by Sir Isaac Newton and Gottfried Wilhelm Leibniz in the late 17th century. The history of calculus is a fascinating story involving many mathematicians’ contributions over several centuries. In this article, we detail how calculus, as we know it today, came about.

The beginning 

The roots of calculus can be traced back to ancient Greece, where mathematicians like Archimedes and Eudoxus used methods of exhaustion to calculate areas and volumes of various shapes. However, it was not until the 17th century that calculus was developed as a systematic mathematical tool.

Sir Isaac Newton

Sir Isaac Newton, an English mathematician and physicist, is widely regarded as the father of calculus. He developed his ideas about calculus in the 1660s and 1670s, although he did not publish his work until much later. Newton’s method of calculus, which he called “fluxions,” was based on the concept of infinitesimals, which are amounts that are infinitely tiny but do not equal zero. He used fluxions to solve problems related to motion and change, including the famous problem of the motion of planets.

Gottfried Wilhelm Leibniz

Almost concurrently, a German mathematician and philosopher, Gottfried Wilhelm Leibniz, also independently developed calculus in the late 17th century. Leibniz’s method of calculus, which he called differential calculus, was based on the concept of the derivative, which measures the rate of change of a function at a particular point. Leibniz’s notation for calculus is still used today, including the integral symbol, representing the area under a curve.

Controversy

The development of calculus was not without conflict. Newton and Leibniz became embroiled in a bitter dispute over who deserved credit for discovering calculus. The controversy lasted for several decades and involved many prominent mathematicians of the time. Ultimately, both Newton and Leibniz are now credited with the development of calculus. However, Newton’s ideas were more widely accepted in England, while Leibniz’s ideas were more popular on the continent.

Real-life applications of calculus

One of the key applications of calculus is in physics, where it is used to study motion and change. Calculus can be used to derive equations for the movement of objects, including the famous laws of motion developed by Newton. Calculus can be utilised in many other areas of physics, including electromagnetism, quantum mechanics, and relativity.

Calculus is also widely used in engineering, where it is used to design and analyse structures, machines, and systems. Engineers use calculus to optimise designs, calculate stresses and strains, and develop models of complex systems. Additionally, it is employed in economics, where it is used to model and analyse economic systems, including supply and demand, production, and pricing.

Today, calculus is a fundamental subject in universities and high schools worldwide. It is taught as a core subject in mathematics and is a prerequisite for many other disciplines, including physics, engineering, and economics. Calculus is also widely used in computer science, where it helps to develop algorithms, model complex systems, and analyse data.

Conclusion

The history of calculus is a fascinating story that involves the contributions of many great mathematicians over several centuries. Sir Isaac Newton and Gottfried Wilhelm Leibniz are credited with the development of calculus, although their ideas were developed independently and caused controversy at the time. Today, calculus is a fundamental concept in modern science, and its applications are endless. It is a subject that has played a crucial role in the development of modern science and technology and continues to be an essential tool for solving complex problems in a wide range of fields.
