## Who Invented Calculus?

Sir Isaac Newton and the German polymath Gottfried Wilhelm Leibniz are both credited with inventing calculus. These two 17th-century geniuses managed to independently develop the basics of calculus in their lifetimes. Sometime in the following century, it became a hot debate as to *which* of these men really invented calculus, but nowadays, we concede that they both did.

### Who is the Father of Calculus?

Generally, Gottfried Leibniz is counted as the “Father of Calculus” and only because he also happened to give it its name. Newton had called it “the science of fluents and fluxions,” which is very on-brand for him. Both names are used today, though we can admit “calculus” is so much easier to say. Depending on what circles you run in, either Newton or Leibniz can be referred to as “Father of Calculus.”

The only other competition (besides Sir Isaac Newton) Leibniz has for the title is, surprisingly, the Greek mathematician Archimedes. Despite living two millennia before calculus’ official conception, Archimedes developed a method similar to differential calculus to find the tangent of a curve. Although not exactly like calculus today, Archimedes was the first person to get close to it with his early concepts, beating out Leibniz and Newton.

## When Was Calculus Invented?

Calculus was independently invented in the later 17th century by the great mathematicians Sir Isaac Newton and Gottfried Leibniz. Their competitiveness peaked by the 18th century when the “who did what when” scandal was called the Newton-Leibniz Calculus Controversy. According to the drama, Newton claimed he invented this new mathematical system, and that he had multiple papers to support his claim – which, were not published. However, he did exchange letters with friends and colleagues, confirming his invention of calculus sometime in the mid-1660s.

Unlike Newton, Leibniz published his findings in 1684, called “A New Method for Maximums and Minimums.” This paper, in support of Leibniz, made cases for differential and integral calculus and helped lead to the development of modern calculus. Despite the heated back and forth of the Newton-Leibniz Calculus Controversy, historians agree that calculus was independently invented by both great minds respectively, as both were inspired by mathematical developments from Isaac Barrow and Pierre de Fermat.

### Calculus in Antiquity

The roots of calculus can be traced back to antiquity, where several ancient civilizations made significant contributions to mathematical concepts that would later pave the way for the development of calculus. Among these early precursors, the ancient Greeks and Egyptians stand out for their foundational work.

The ancient Greeks, renowned for their mathematical acumen and Greek mathematics, laid the groundwork for calculus with concepts like the Method of Exhaustion. This method, championed by mathematicians like Eudoxus and Archimedes (unsurprisingly), involved approximating the area of irregular shapes by inscribing and circumscribing them with simpler polygons. This ancient approach to dealing with infinitesimal quantities foreshadowed the calculus concept of limits and infinitesimal calculus.

Otherwise, Archimedes, one of the most brilliant mathematicians of antiquity, made crucial contributions to integral calculus. His method of exhaustion was employed to calculate the area under curves and the volume of irregular solids, demonstrating a primitive form of integral calculus centuries before its formalization.

Egypt has a rich mathematics history itself, with its contributions to early calculus being comparative to the Greeks. They had calculations for the area and volume of concrete numbers, though their system was unrefined overall. Early Egyptian mathematical systems are largely drawn from the knowledge within the Moscow Mathematical Papyrus.

While these early mathematical insights were remarkable, they lacked the systematic framework that would come to define calculus. Nevertheless, they served as essential precursors to the revolutionary developments that would take place in the 17th century, ushering in the era of modern calculus.

### Calculus of the 17th century

The true birth of calculus occurred during the transformative 17th century when two remarkable mathematicians, Isaac Newton and Gottfried Wilhelm Leibniz, independently made groundbreaking strides in calculus development.

In England, Sir Isaac Newton was at the forefront of this mathematical revolution. He is known for scientific calculations and the invention of calculus, particularly his progress in physics and universal gravitation. As it is, Newton devised a novel branch of calculus known as differential calculus.

Newton’s genius lay in his formulation of the fundamental concept of derivatives, which allowed for the precise calculation of rates of change. He introduced the notion of instantaneous velocity and change in his seminal work “Philosophiæ Naturalis Principia Mathematica” (Mathematical Principles of Natural Philosophy), published in 1687. This work, commonly referred to as the Principia, laid the foundation for modern physics and engineering.

Simultaneously, on the European continent, the German mathematician and philosopher Gottfried Wilhelm Leibniz was independently developing integral calculus. Leibniz introduced the concept of the integral sign (∫) and a comprehensive notation system, making calculus more accessible and adaptable. His notation, still in use today, greatly simplified the representation of mathematical operations. Leibniz’s pivotal work in this field culminated in the publication of “Nova Methodus pro Maximis et Minimis” (A New Method for Maxima and Minima) in 1684.

As the development of calculus progressed, a bitter dispute erupted over who should be credited as its true inventor. Newton and Leibniz, unaware of each other’s work, published their findings independently, which led to accusations of plagiarism and priority disputes between their respective supporters.

Oh boy…who could have guessed there was so much drama in the math community?

## Global Recognation of Newton and Leibniz

The Newton-Leibniz priority dispute persisted for decades, with the scientific community divided over who deserved credit for inventing calculus. Eventually, both mathematicians were recognized for their significant contributions, with the recognition that they had independently developed different aspects of calculus. Guess one could say great minds think alike.

In 1712, the Royal Society of London declared Newton as the original inventor of calculus, acknowledging his foundational work in differential calculus. This recognition solidified Newton’s place in history as a key figure in the development of calculus. On the other hand, Leibniz’s notation and integral calculus notation became widely adopted due to their simplicity and utility. While he was not credited with the invention of calculus as a whole, Leibniz’s notation system revolutionized the field and ensured his enduring legacy.

The recognition of both Newton and Leibniz highlights the complex and collaborative nature of scientific discovery, where multiple individuals can contribute to a groundbreaking field simultaneously, each leaving an indelible mark on the history of mathematics. Thus, the question “Who invented calculus?” cannot be easily answered.

## Why Was Calculus Invented?

The invention of calculus was the natural product of trying to understand the world around us. Since calculus can be used in physics, engineering, and astronomy, it is a universal tool that makes life a little easier. Well, for those that are mathematically savvy. Otherwise, calculus could seem extremely obscure to some folks.

In short, calculus was invented because it needed to be. Early mathematicians and scientists may not have exactly known this, but they knew it was a necessity to understand other formulations and systems. Calculus was one of many keys needed to unlock the doors of physics, algebra, economics, and other sciences.

## Predecessors and Influences of Calculus

The roots of calculus extend far into antiquity, where mathematical concepts and methodologies began to take shape, setting the stage for the eventual development of calculus.

The ancient Greeks, renowned for their mathematical prowess, laid the groundwork for calculus with concepts such as the Method of Exhaustion. Mathematicians like Eudoxus and Archimedes employed this method to approximate the areas of irregular shapes by inscribing and circumscribing them with simpler polygons. This ancient approach to dealing with infinitesimally small quantities foreshadowed the calculus concept of limits.

More specifically, Archimedes’ Method of Exhaustion was employed to calculate the area under curves and the volume of irregular solids, demonstrating a primitive form of integral calculus centuries before its formalization. His insights laid the foundation for understanding the accumulation of quantities over infinitesimal intervals.

If we skip ahead to the Islamic Golden Age, we have Ibn al-Haytham, the “Father of Modern Optics” who contributed to mathematics by creating a system for infinitesimal calculus. The system was largely expanded upon from previous works by Euclid and Thabit ibn Qurra.

### Calculus in the Renaissance

There are several Renaissance minds that predate Newton’s work and acted as an inspiration to the polymaths of the 17th century. Johannes Kepler, the renowned astronomer, introduced the concept of infinitesimals in his work on planetary motion, contributing to the development of calculus. Additionally, René Descartes’ development of coordinate geometry provided a crucial framework for understanding curves and functions, a fundamental aspect of calculus.

By the 17th century, mathematicians like John Wallis and Pierre de Fermat made significant strides in understanding mathematical principles related to calculus. Wallis, for instance, introduced the concept of the infinite product for calculating π (pi), while Fermat explored techniques for finding maximum and minimum values of functions.

## Calculus and Collaboration in Mathematics History

Throughout history, mathematicians communicated their findings through letters and publications, sharing insights and building upon each other’s work. This exchange of ideas helped refine and develop mathematical concepts, ultimately leading to the formalization of calculus.

While Newton and Leibniz are often credited with inventing calculus, it is important to acknowledge the contributions of countless mathematicians who came before them. From ancient Greeks to Renaissance thinkers, these individuals played crucial roles in shaping the mathematical landscape, paving the way for the revolutionary developments of the 17th century.
