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.

@postyoda1623 5 лет назад

Should not forget about Alhazen.

@jaimeduncan6167 5 лет назад

Ferrusian Gambit interesting. I understand that Newton was the first to come with the idea of limits, it’s that but also questionable? The other point is finding the areas below a curve is not. The same as integration l: did this guys found a general approach ?

@thejiminator8816 5 лет назад

Or archimedes?

@thejiminator8816 5 лет назад

@@jaimeduncan6167 That's precisely the point, if your saying about Alhazen (who found the area under the Paraboloid using polynomials) this is just what archimedes did in the sense of finding areas and volumes of things. But integration isnt just about areas and volumes!, its the inverse of differentiation. Cavalieri like alhazen , could integrate x^n , cavalieri also came up with his wonderful principle.

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. Great video, thanks as always :)

@m93sek 5 лет назад

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 Leibniz had published his work first, but Newton's supporters accused Leibniz of plagiarizing Newton's unpublished ideas.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."

@eprjct 2 года назад

I always go for Leibniz on Calculus. The way we view calculus today is almost identical to how he viewed. His view is way more intuitive and also better to navigate. If you think Newton and Leibniz are equally important, try using his way of Calculus.

@boogerie Месяц назад

Touche'. And in fact for more than a century after Newton's death his notation (using a dot) was the one taught in the UK, while on the continent Leibniz's notation (using a "d") prevailed. As a result science stagnated in the UK while it progressed by leaps and bounds. Leibniz's system was adopted when some young upstart mathematicians argued for its superiority. Among them was young Charles Babbage who wrote a satirical essay about British mathematics "dot-age" as opposed to continental "d-ism."

@reinerjung1613 2 года назад

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.

@archivesoffantasy5560 2 года назад

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

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.

Depends on your philosophical bent. Not many Physicists think that our math describes the universe directly; so they’d say that they had indeed invented a tool which can be used to model the universe.
