    back to math history , i am very happy :) thank you

    I'd say the Indian Period came before the Greek but after the Babylonian. The Shatapatha Brahmana from the 1000 BC shows they did know of the Pythagorean Theorem and properties of Roots (which are very Babylonian mathematically).
    Had we more history, I am confident there's a connection between Babylonian and Indian mathematics, where we'd find Babylonian Methods in Indian Mathematics.

    The irony of looking into the past to get information about the future is astounding. Empty space has never been measurable and will never be measurable. I suspect this is the point Gauss raised regarding humans can not reason an understanding of space. It appears Gauss was the first to comprehend the inadequacy of Geometry in mathematics and physics. Humans can only observe a picture of a point. It is not possible to see a point in space we can only observe the past.
    Gauss: I am becoming more and more convinced that the
    necessity of our geometry cannot be proved, at least not by human
    reason nor for human reason. Perhaps in another life we will be
    able to obtain insight into the nature of space which is now
    unattainable.

    I am amazed by ancient civilizations that did ease computations even without yet use of zero numerals - for e.g. Mesopotamian use sexagesimal numbers without zero place holders and Chinese use blank or no bead setting in counting rods and abacus. However, the later use of zero undeniably enhanced the number systems and math.

    29:45 Not so fast! Please bear with my second-language English for a short while.
    This video IMHO needs at least an annotation, as well as the other ones mentioning that spherical circles are needed in order to map distances on the Earth. Perhaps a separate video should be done in regard to what follows. The ill-advised tirade from 31:35 to 31:50 needs to be addressed with some counter-intuitive facts, not all that are needed to 100% refute the *Ball Earth* model of course, but nevertheless enough to get one to doubt the current dogma.
    I'm bringing the subject up since I'm sure elegant math such as the one discovered and outlined in such a great way on your channel will help bring closure to this subject, especially in regards to the appreciation of the effects of perspective.
    In the blue pill corner: all the telemetry from the sun-observing satellites, with Mercury recently transiting on front of the sun and lots and lots of coherent data from outer space provided by probes. The Electric Universe model is highly appealing in regard of making sense of the observations, such as comet 67P being a piece of rock instead of low-density ice and regarding the basic driving force of our observable universe. The work of Ben Davidson @ Suspicious0bservers (recent major videos to get a fast grip on current world events: The #1 Risk to Earth and The Sun and Storms: May 2, 2016) and of the ThunderboltsProject toward the goal of understanding our observable universe, both available on YT, are professional-level and very convincing.
    In the red pill corner: Both arguments used in the MathHistory30 video are demonstrably false: against the boat argument, just use a powerful zoom and you'll beat the perspective effect and get to see the ship upright up to impossible distances for the Ball Earth model, and against the shadow on the moon argument, the shadow is caused by something else (Rahu in ancient mythologies), as strange as it may seems, since both Sun and Moon have been seen at the same time in the same daytime sky during a lunar eclipse! There's (surprisingly? :O) a lot of evidence showing the Earth is a flat plane, let's state a few that come to mind right away:
    * View from airplane windows, compare the plane Earth case vs the sphere case with a radius of ~four thousand miles, think about it, the horizon should fall and it doesn't;
    * Mechanical gyroscopes, again planar vs spherical cases, they simply can't work on a spherical Earth;
    * Footage from high altitude balloon and airplanes that are showing a flat plane and the hotspot from the sun (a flat line shows on the footage taken from the inside of the Highest jump Red Bull Stratos capsule, when the door opens)
    * All the fakery from NASA, here's a short resume: the faked moon landings (Bart Sibrel got original footage of inflight fakery, Jarah White's peer-reviewed, high quality effort of debunking on YT@WhiteJarrah); ISS footage containing air bubbles and evidence of vomit comet footage ( v=9X0HgFWsNlk , at 1.18x speed using libsamplerate's best sinc resampling under VLC =O), raw footage of white-meshed blue screen technology streamed on the main screen of the ISS control room while filming G. Bush senior in a wheelchair, there's footage showing the Chinese space agency faking its first extravehicular sortie, with air bubbles present, no true image/footage of the Earth from space e.g. The most recent Earth Polychromatic Imaging Camera footage from the DSCVR satellite from 2015 with the moon flyby is so evidently faked), the 23.4/66.6 degrees tilt, plane trigonometry is used in maps at sea, the logos of the United Nations and other *plane*tary organizations, etc, etc.
    To go further, I'd suggest a recent expose outlining many facts pointing toward the flat circular Earth, (and some well-founded speculations about a dome above the atmosphere) that are well presented in an accessible format with great video addition to the original talk show footage (light PG13-rated humor is present): v=eNbjFoA8sJQ .
    Some words of caution for the younger minds surfing by themselves on Internet that are willing to go down this Rabbit Hole. It's a very mysterious and multifaceted subject, with many ramifications, both leading to and coming from it. In this day and age of Information, answers are available, as well as so much more disinformation and controlled opposition, put out there in order to lead astray, away from the truth: the more malleable minds will waste their time and energy on non-sense: you've been had, your efforts are diverted, the other camp wins; the others will be discouraged from further investigation by the shear amount of non-sense they will encounter and that they need to process if they too dare to stray away from group-think... I'll also mention Fravia+ and Charles H. Moore, just in case one need a change of fantastic subject to research and they are into the inner working of computers, magnificent elegance of the work of pioneers and digital freedom!
    It is my most sincere belief that indisputable Mathematics such as Rational Trigonometry, Universal Geometry and Chromogeometry can help bring definitive (and new!) arguments to the table in a format that anyone can understand with arguably the minimum level of mathematics required and thus firmly close many vain topics Science and Physics, such as the truth behind the Ball Earth myth or fact once for all, especially through an accessible appreciation of projective geometry and perspective in action.

      Adam Marquis There is far more evidence showing that the world is not a flat plane, of course. The idea doesn’t stand up to any amount of critical inquiry.

    Good video for someone who is new to the topic. But for someone who has already studied basic astronomy and ancient astronomy (just reading wikipedia and google) this does not add anything new. You spend almost half of the video explaining the current view and basic concepts of astronomy, then the other part just explains the celestial coordinate system. To make it worse, I could not find Part II in your playlists. Can you please share it with us? Otherwise this video isn't very useful (there are many other videos in YT explaining astronomy much better and more accurately than this).
