Newton vs Leibniz (feat. Hannah Fry) - Objectivity 190

Hannah Fry returns to The Royal Society to investigate one of the juiciest debates in the history of science! More links below ↓↓↓

Featuring mathematician and broadcaster Hannah Fry speaking with Brady.

Hannah and Kieth. One is a mathematician, the other a head librarian... Together they fight crime!

[No-pmss]

Absolutely didn't come here just because of Hannah...

[WilliamLeeSims]

In both calculus and math history it was briefly mentioned that there was a controversy between Newton and Leibniz. I didn't know it involved a timeline of letters! Can you imagine a modern day version of this with a compilation of emails, tweets, texts, and saved instagram photos?

Hannah's enthusiasm is infectious, this is one of the best videos you've done Brady.

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.

My favorite Hannah Fry quote " I thought it was an integral, but it was just a curly F."

[Lupiscanis]

A) Could watch Hannah Fry all day. B) Gossip! C) A++ video.

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 :)

Well, Hannah has definitely won my prestigious Science Communicator Crush 2018 Awards and the jury decision wasn't even close. So there.

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 Leibniz had published his work first, but Newton's supporters accused Leibniz of plagiarizing Newton's unpublished ideas.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

Those are three people having a good time. Love it!

[vnceigz]

Wow, she was giddy. Mathematics fan-girling at is fullest. 😁

[antonioarroyas]

Loved that last shot of Hannah's book. Keep up the good work Ojbectivity, Brady and all the others that make this kind of content possible for the world to see.

[gasser]

Yay, Hannah! She's so magical! Her eyes...her excitement over this kind of stuff...!

[Goryllo]

Commercium epistolicum means "exchange of letters", the word commerce comes from commercium (which in fact is a form of exchange) while epistula (letter) is the root of English words like epistulary (relative to letters).

The first humans doing integrals were Greeks. For example they sandwiched the area of circle between nr^2sin(π/n)cos(π/n) <A<nr^2tan(π/n) and intuitively took n tends to infinity.

This was a great Objectivity video Brady. I really enjoyed this one. 😍

[olivierrondot]

I really like the concept of this particular video; to invite someone that is familiar with the field that is the subject of the item or document featured. I feel like it brings a new depth that makes the video even more interesting. I would love to see more of this concept in the future with other experts.

[quahntasy]

Hannah is my favorite!! Could watch her go giddy all day!

[TurdFurgeson]

Leibniz: I've got it!

Netwon: Yeah? Well I loosened it up!
