It should be corrected that at 4:30, it was not the first time someone integrated. Bonaventura Cavalieri had been integrated specific functions many years before Newton, and John Wallis in the generation before Newton had expanded the range of functions that integrals could be applied to. Newton (and Leibniz) were the first to join differentiation and integration together in a coherent comprehensive theory.

Leibniz invented the integral symbol : ∫ and also made calculus much "user friendly" than Newton's geometrical approach. He also was more interested in the mathematical side of it rather than Newton who came to it via physics. Anyway, both of them invented/discovered calculus at the same time via different ways.

Wiki: "The calculus controversy (German: Prioritätsstreit, "priority dispute") was an argument between the mathematicians Isaac Newton and Gottfried Wilhelm Leibniz over who had first invented calculus. The question was a major intellectual controversy, which began simmering in 1699 and broke out in full force in 1711. Leibniz had published his work first, but Newton's supporters accused Leibniz of plagiarizing Newton's unpublished ideas. Leibniz died in disfavor in 1716 after his patron, the Elector Georg Ludwig of Hanover, became King George I of Great Britain in 1714. The modern consensus is that both men developed their ideas independently."

This is interesting so I looked it up in some history books and it seems that Leibniz and Newton independently invented the same thing. However, Leibniz first developed integration and Newton differentiation. So they are both right and wrong at the same time.

Newton first used it in 1666 and Leibniz in 1675. The controversy is where Leibniz got inspired by letters he may have read from Newton during those nine years. But Leibniz developed the calculus further with a more approachable way than Newton, so both deserve credit. I’ve seen someone say Newton set the seed and Leibniz watered it

I can't remember the last time I used Newton's notation for differentiation. It has been useless to me in studying differential geometry. Leibniz notation is much clearer when visualizing the geometry even if it's more to write.

Thanks Hannah, i got excited as soon as i read the title of this video! Math passionados could never walk past such a find and not say something

They both have equal credit in the discovery of Calculus, since they both arrived to the notion from a different perspective that is pretty much impossible to fake in such short amount of time, specially at the rate speed information spread at the time. Is just that the british are a tad jingoistic and think their s**t smells better, particularly when it comes to continental Europe. But in an ironic twist of fate, we all use Leibniz notation for differential and integral calculus, simply because is far better than Newton's.
