NOTE: The intro screen says Lagrange, but this is indeed Cauchy!
In this episode, we cover the history of Augustin-Louis Cauchy, a 19th century French mathematician, engineer, and physicist who was notable for developing a great majority of the foundations of complex analysis, and is only second to Euler in terms of mathematical productivity.
I go a bit deeper into the mathematics in this video, but still the primary focus is on Cauchy's history.

Learning about the history of mathematics/mathematicians makes the study of mathematical theories much more interesting ! Great video by the way.

100% agree

@EMC273 6 месяцев назад

agreed

@anthonyvargas7564 3 месяца назад

Agreed! Honestly if math was taught like this from the beginning starting with the historical context and the methodologies that sprung out of that context I think it would make that whole subject and feel a lot more appealing to people who hate math, honestly not sure why that's not hot in that way cuz Jimmy has 32 blueberries and what the hell else ever theyre always yappin about in schools

@franciscorosalbarran4857 2 года назад

Thank you Andrew!! I just knew Cauchy from the Cauchy convergence of a serie. He actually did many things. Love those videos Can you do one about Hermann Schwarz? 🙏 PD: I think the title at the beginning of the video mentions Lagrange?

@moderndaymath 2 года назад

Yeah I finished the video very late and forgot to change my template for the intro screen 😂 I made note of it in the YT description. I'm hoping to make a video on Schwarz next year!

@karabodibakoane3202 2 года назад

Convergence of a series you say. So basically you're saying you didn't learn about the epsilon-delta definition of a limit?

@thea.igamer3958 2 года назад

Excellent. Your efforts are highly appreciable. Indeed, a great distinguished service, here in RU-vid. There are lot of interesting mathematicians on the list. Consider Hermann Grassmann, George Boole, Stefan Banach etc.

@pabloa2228 11 месяцев назад

I just learned the Cauchy-Euler equation in Diff-EQ and had no idea who this dude was. Thank you for your help

@yeonil946 2 года назад

Thank you for the video :))) I notice his name quite often both in my differential and numerical analysis classes… no wonder why 800 research paper 🤯

@Nylspider 2 года назад

Hell yeah dude

@thomasmurff3471 2 года назад

You should do Galois!!

@morgengabe1 10 месяцев назад

I imagine Cauchy just didn't want to argue with Abel and didn't feel inclined to hold any punches that weren't made in the interest of reason. These people came up with limits, they were not wreckless/unscrupulous. Overly cautious, perhaps.

@adambruce1688 2 года назад

This is a rather bigoted view of the personality of such a great man, brought about, no doubt, by too much reading of left-wing French sources (who, yes, hated him solely for his religious and political convictions).

@jontallen3319 2 года назад

It may sound bigoted, but its accurate. Being great is uncorrelated to being a bone-head, or having an opinion that is hard to justify. Cauchy was what he was, and this video is quite accurate as far as I can tell.

@adambruce1688 2 года назад

@@jontallen3319 His history is about as accurate as his French pronunciation. Cauchy *was* what he was--an incredible genius to whom we are all indebted.

@trubblman Год назад

This sounds a lot like the characterizations written by mathematicians. Catchy apparently was a royalist and strict Catholic. With such beliefs his math talent is startling

@ZarNakano Год назад

@trubblman you're not going to believe how religious people like Newton, Leibniz or Euler were Personal beliefs have nothing to do with your ability to do math

@trubblman Год назад

@@ZarNakano I wrote religious AND political. However religious a person is, no one who has use of reason believes in transubstantiation. I have no doubt that as a staunch Catholic Cauchy took such foolishness literally

@jontallen3319 2 года назад

This is a really important review of Cauchy's life. I learned a lot of important details. Thank you for making this video. There is also a somewhat minor mistake at the end during the summary where it says he contributed to Fourier Transforms. I think that should be the Laplace transform. See the discussions in my book on Cauchy's important math contributions: jontalle.web.engr.illinois.edu/MISC/Springer.19/2020_Book_AnInvitationToMathematicalPhys.pdf
