  • How much did Kepler know about gravity? A lot, it turns out.

    This is one of the best parts of the story, but your original Kepler videos were certainly not lacking in quality because of its omission. This followup video is just icing on the cake.

    Honestly, this is one of the best channels on RUclips.
    It seems like the "forces" were defined in terms of gods and angels by the ancients. In fact, today, we're getting away from calling gravity a "force" because of how we observe it working. It's more like acceleration - the result of a force having been or being applied.
    Matter plus the space it occupies results in gravity and is not a force being generated by an object. It's like we're learning that it's not gods and angels all over again.

      I don't follow this argument that gravity is not a force. You don't feel gravity because it's a force that's spread out evenly throughput your body. If the same could be achieved with a different force it would also not feel like a force, because your whole body would be accelerating.

      @@trucid2 gravity is defined as a force in Newtonian mechanics, in Einstein’s relativity it is an effect caused by the curvatures mass makes on spacetime. Same reason why even light bends around massive objects.
      There’s videos on RUclips that explain why gravity is not a force, i.e. how relativity explains the attraction masses feel.

      @@pansepot1490 Yes, I think once we unify QM and GR we'll see that gravity is just another force. For example there's a formulation of GR through a variable speed of light.

    I'm always fascinated to discover what knowledge was known or theorized at any given time in history. In school, there's only so much time to spend on history that you're only really taught the highlights, but man there's so much more! Thanks for filling in so many of the gaps with all your videos!

    I like these little 'microdoses' you've begun sprinkling in wih the larger treats!
    Partly because they bridge the gaps, and partly because I hope they're a litle quicker and easier to produce and will therefore be a little more algorithm-friendly.
    I do feel your channel deserves to be bigger than it is but, at the same time I want you to continue with your beautidully researched content with it's scintillating narration which must take at least as much crafting as the factual research iself.
    Your channel is an absolute jewel in a sea of mediocrity and well do I love it!

    It would seem Kepler was not nearly enough credited with just how incredibly ahead of his time he really was. Thank you for this insight. Im always amazed that somewhere in history almost everything we take for granted today was hypothesized and to some degree first understood by a single man. Those single men deserve every accolade we could possibly bestow. Rockstars the the lot, even the ones who were somewhat off the mark but got the conversation going.

    Ok so this is something unexpected and, humbling too. I never noticed any of this; duh. You know, it strikes me as an interesting time to have missed. I mean there was a lot of good and important work going on but it was still all a bit of a train wreck until that Brit and German started scraping, ( and now we celebrate Newtonmass on the 25th of December). What I am failing at expressing is that I have empathy for the Kepster. He was so close so many times and then, there were all those times he was just throwing fish to Cthulhu...way out there man. I don't expect there is an afterlife, I have no idea just a tingling sense of mortality but, if there is I expect Kepler may have had a hard time you see. "No Kepler," says the archangel."It all goes like this."
    "You mean it doesn't..." replies Kepler.
    "No no not even a little."
    "Ohhh." scoffs Kepler."Why s the grass green then?" He demands.
    Smiling the angel answers."Because of the chlorophyll."
    He had a rough slot in history but I think he did ok. Did better than his whack job mentore. People get the Kepler award and, isn't Tycho Brahe a brand of cheep liquor? Nose cream! My mom used Tycho Brahe nose cream.

    Newton, himself acknowledged his precursors "If I have seen further than most most, it is by standing on the shoulders of giants." Kepler noted the elliptical orbits of planets (which Galileo denied). Galileo noted the parabolic nature of gravitational acceleration. Newton formulated a gravitational theory, from which both observations would follow.

    This is what learning used to be like. Instead of this rote memorization and spill of facts and theory unto inquisitive minds. Which seems the norm in the educational system today.
    Someone talks about what they know, someone else asks a question, and both are better off and more learned in the end!

    Ah, the cult of the genius. I think the average person imagines science as long stretches of ignorance punctuated by a brilliant genius who reveals a major truth to us, like a prophet of a God of Science. So, Newton "discovered" gravity and Einstein "discovered" relativity. In reality, of course, it's a long process, and you can trace a line of development in thought and conversations that led to a final and more complete formulation.
    Which, now I think about it, is actually the point behind this series. You're outlining more of that conversation from geocentrism to heliocentrism, and how that conversation developed, and who some of the louder voices where (and you even touch on some of the quieter voices). So that question actually makes a lot of sense in that context: "How did people know about gravity before Newton?" answer: "Newton didn't discover it, he just created the most complete formulation of it until Einstein. He was the capstone of a very long movement."

    • @manofcultura

      Yeah this is what I like about Nicks narrative style. The science of discoveries and their acceptance by wider academia is a fascinating historical journey. It makes me think about how confident we are in our current understanding and how it must be something that will be viewed as quaint and chuckled at 300+ years from now.
