    For the 100th, we have the entire foundation of modern maths, an important cornerstone of classic physics, an absurdly important piece of history, and a book about fish.

    • @Garbaz

      "the entire foundation of modern maths" - NO, not at all! In fact, Newtons mathematics were rather irrelevant. Sure this book was great, but barely relevant for mathematics.

      Not sure why you linked that wiki article, it doesn't support your conclusion in the slightest. Although there were people before Newton who helped develop the field of calculus such as Kepler, its a big stretch of the history to suggest that Isaac Newton's mathematics were irrelevant. As the wiki explains, while the first book of the Principia was created almost entirely using his fluxions, he chose to couch his new math in the older analytic methods of the ancient geometers. This was done partly to pay homage to the giants upon whose shoulders he stood (Pythagoras, Euclid, ect.) as well as make sure that only the handful of other mathematicians close to his proficiency could understand. Unfortunately for him this plan backfired and caused a whole lot of headaches for him during the dispute with Leibniz over the priority of discovery.

    • @Garbaz
      @Garbaz 8 ปีที่แล้ว +2

      David W The wiki article was something for the commenter to read before writing dumb comments for cheap likes. It wasn't intended to make or support any point.
      About calculus: There is no doubt he invented calculus. But Leibniz did as well, and it's his version and notation we use today.
      By no means do I question Newtons brilliance, the fact that he invented calculus (as well) or that his maths was excellent and complicated, but neither does today's calculus nor most of mathematics depend on his work.
      *The point being, that I was annoyed by the fact that the top comment was a plainly uninformed and empty praise.*

      The fish book was probably more important than you realize, since it would indicate "this is a fish, not a sea serpent".

    I visited the Royal Society on Friday, but of all the days, most of it was closed for a function/staff Christmas dinner/other. I was allowed to look around the astronomy exhibition on the lower ground floor, and the bits around the entrance, including the Mace from Charles II! That was my favourite, but hiding around the corner was a chest with an NFC tag on the wall above it. When I touched the tag, it opened up Objectivity #33 Treasure Chests! Imagine my surprise and delight from not initially recognising the chest.

  • @jmiquelmb

    I mean, the Principia looks nice, but I bet they could have printed at least 5 more fish books with the money they used for it.

    What a way to bring up the century. After a nervous wobble on 99, a well-timed off-drive brings up the ton for Haran. He raises his bat to the crowd and salutes the dressing room. 100 not out and it looks like this partnership with Moore has a long way to go.

      And I always thought it was pronounced prinCHipia, with a 'ch' sound, like that in the word 'choose', for example. Smaakjeks K has a point -- no one truly knows exactly how it's pronounced today, since Latin is a dead language.

    Bravo Brady! Congrats to you and all who enter your camera's field of view and all who work behind the scenes.
    Your videos encompass virtually all the presentation techniques I see on TH-cam: Off-camera interviewer, on-camera interviewer, interlocutor, presenter, talking-head, and the list goes on, ending with being "just" the cameraman, knowing when to let your subject run free.
    When I started toying with the idea of making my own channel on a topic I care deeply about, the first question I had to ask myself was what "kind" of channel did I want? I've been gnawing on it for over a year, and finally hit the obvious end-point: WWBD? What Would Brady Do? The initial answer echoed in my mind: "Take a blasted videography class, dammit!"
    Any chance you'll produce your own videography class?

    Very interesting video, its always so cool to see the work of the geniuses of the past and ponder about the significance they have acquired, centuries after their very deaths.

      simontay1984 I'm writing my thesis on newton, and while i certainly agree he isn't fully appreciated by history, the book is mostly diagrams, lemmas, and definitions concerning the calculation of planetary orbits, not sure how practical that is for the everyday Joe blow these days.
