But, since Leibniz had published first, people who sided with Leibniz said that Newton had stolen the ideas from Leibniz. He tried to establish his priority in that fashion, but what followed were accusations that Leibniz had read some of Newton’s manuscripts before he conceived his own ideas. Even a mathematician wouldn’t know from the actual translation of the sentence exactly what it was that he had done. Even though you read the sentence, it means very little to anybody. He put them in order and this was what he included in this letter to Leibniz to establish his priority for calculus. He said there are six a’s, two c’s, one d, 13 e’s, two f’s. He took that sentence and he took the individual letters a, c, d, e, and he put them just in order. In the letter, he encoded a Latin sentence that begins, “Data aequatione quotcunque…” It’s a short Latin sentence whose translation is, “Having any given equation involving never so many flowing quantities, to find the fluxions, and vice versa.” This sentence encapsulated Newton’s thinking about derivatives. Leibniz’s Paper on CalculusĮven a mathematician wouldn’t know from the actual translation of the sentence exactly what it was that he had done.īut when Newton began to realize that Leibniz had the ideas of calculus, which he himself began to realize in the 1770s, Newton’s response to ensure that he received the credit for calculus was to write a letter to Leibniz. This is a transcript from the video series Change and Motion: Calculus Made Clear. This wasn’t just hearsay, and he used the techniques of calculus in his scientific work. None of his works on calculus were published until the 18th century, but he circulated them to friends and acquaintances, so it was known what he had written. The paper he wrote in 1676 was published in 1704. The one he wrote in 1671 was published in 1736, nine years after his death in 1727. The one he wrote in 1669 was published in 1711, 42 years later. In time, these papers were eventually published. He wrote two additional papers, in 16 on calculus, but wouldn’t publish them. In 1669, he wrote a paper on it but refused to publish it. Between 16, he asserts that he invented the basic ideas of calculus. The controversy surrounds Newton’s development of the concept of calculus during the middle of the 1660s. Isaac Newton, the English physicist (Image: Godfrey Kneller/Public domain) Many other mathematicians contributed to both the development of the derivative and the development of the integral. Fermat invented some of the early concepts associated with calculus: finding derivatives and finding the maxima and minima of equations. As Newton’s teacher, his pupil presumably learned things from him. Newton’s teacher, Isaac Barrow, said “the fundamental theorem of calculus” was present in his writings but somehow he didn’t realize the significance of it nor highlight it. It is is an incremental development, as many other mathematicians had part of the idea. Sir Isaac Newton was a mathematician and scientist, and he was the first person who is credited with developing calculus.

By Michael Starbird, PhD, The University of Texas at Austin Stretching from the days of ancient Greece, calculus was developed and refined throughout the centuries, up until the time of Newton and Leibniz.
