Instead of an apology, he got a counterattack: a letter spelling out all of the claims against Leibniz in greater detail. He wrote, enraged, to the Royal Society of London demanding an apology. He stated that Newton was the inventor “beyond any shadow of doubt” and that Leibniz had published it “having changed the name and symbolism.” This was too much for Leibniz. Soon, this friend published a paper in which he cut right to the chase. Was Leibniz trying to say the same about himself and Newton? Another friend of Newton, however, pointed out that the analogy could be interpreted a different way: one of the two mathematicians Leibniz mentioned had probably plagiarized the other. Leibniz probably just meant to say that he and Newton, like this other pair, had combined their ideas to come up with greater ideas. In it, he compared Newton and himself to two other mathematicians. This referred to the letter Newton sent Leibniz with the inscrutable jumbled message-apparently the idea was that Leibniz could have both unscrambled it (not likely) and gleaned its meaning (even less likely).Īfter this episode, the controversy cooled until Leibniz wrote a review of two of Newton’s works in 1705. But Leibniz, who was a careless worker, wrote an article about the problem that seemed (to Newton’s friends) to imply that Leibniz had invented calculus and that Newton was Leibniz’s student.Ī friend of Newton’s then angrily wrote an analysis of the challenge problem in which he indirectly accused Leibniz of plagiarism:Īs to whether Leibniz, second inventor, borrowed anything from him, I prefer to let those judge who have seen Newton’s letters and other manuscript papers, not myself. Newton, of course, solved the problem easily, as did Leibniz. It started in 1696 when a friend of Leibniz published a challenge problem that required calculus in the Leipzig Acta hoping that Newton wouldn’t be able to solve it, thus proving that Newton had stolen calculus from Leibniz. It was their friends who really turned them against each other. Newton’s point was that he had staked a claim to the concepts in 1676, even though the secret message didn’t really communicate anything to Leibniz…or anyone else.Īt first, Newton and Leibniz were both inclined to give the other credit for being an independent discoverer. Also never mind that Leibniz couldn’t read the message because the letters were all out of order. Never mind that no one knew what “fluxions” were, since Newton had invented the word. That way, he could point to it later for proof, but Leibniz couldn’t steal it. The secret message was “Given any equation involving flowing quantities, to find the fluxions, and vice-versa.” When Newton wrote the letter, he had wanted to establish proof that he had discovered a fundamental theorem of calculus, but he didn’t want Leibniz to know it, so he scrambled all the letters of it together. In this letter, Newton had concealed the meaning of a sentence by jumbling all of its letters. In fact, in a note on this theorem, Newton revealed a secret message from one of his letters to Leibniz. But his first public hint was in his greatest work published in his lifetime, Principia Mathematica (1687), when Newton tossed in a theorem about differentiation, one of the basic operations of calculus. Two letters about calculus topics even went to Leibniz that year. Starting in 1676, he circulated unfinished papers privately among his friends that hinted at calculus concepts. However, Newton had planted a few clues about his pioneering work in calculus. Leibniz, a leading philosopher and mathematician, beat him to the punch by publishing a brief summary in the Leipzig periodical Acta Eruditorum in October 1684. Because of his hesitation, he didn’t get any of his work on calculus into print until 1704. He was one of the most innovative thinkers of his day, making breakthroughs in physics and mathematics that inspired vast new fields of study, but he never felt his work was quite ready to go to the printer-he always wanted to make changes or write another draft. None of these coincidences, however, snowballed into an argument as ugly as the one that developed between Isaac Newton and Gottfried Wilhelm Leibniz over the invention of calculus. Charles Darwin and Alfred Russel Wallace both hit upon the idea of natural selection. Michael Faraday and Joseph Henry independently discovered electromagnetic induction. Science has seen a number of simultaneous discoveries. Leibniz had probably both reached their limit as well. By the time they were done arguing about who had invented it, Isaac Newton and G. The following is an article from Uncle John’s Bathroom ReaderĬalculus involves the study of limits.
