The History of Non-Euclidian Geometry - Squaring the Circle - Extra History - #3
Added 2018-06-08 17:30:02 +0000 UTCEuclidean geometry eventually found its way back into Europe, inspiring René Descartes to create the Cartesian coordinate system for maps, and Isaac Newton to invent calculus. Both these tools helped humanity understand the world better.

2018-07-02 20:08:57 +0000 UTCsquaring the circle referred to constructing with a compass and straight edge which was shown to be impossible (by Galois or someone?)

2018-07-02 20:07:14 +0000 UTCI don't think it's fair to say that Newton solved the squaring the circle, since the Greeks also knew how to get a square arbitrarily close to any area via rational approximations Also it should be noted that archimedes calculation of the area of a circle basically is a more rigorous version of Newtons ideas for calculus. see here: <a href="http://www.ams.org/publicoutreach/feature-column/fc-2012-02" rel="nofollow noopener" target="_blank">http://www.ams.org/publicoutreach/feature-column/fc-2012-02</a>

2018-06-09 20:58:55 +0000 UTCNick's art and animations are *really* a great fit for the Extra Credits family of videos. Youtube education videos are always about mixing an entertaining personality and education, and I feel like this style sets the personality so well. I laughed out loud at the living triangle in motion. It's so crisp, but also super concise. Keep up the good work!

2018-06-09 17:56:07 +0000 UTCOh. Like you said, I thought an integral was just a Riemann sum to an infinite limit. So, I thought the to were phrases were interchangeable. Thanks for the clearing that up.

2018-06-09 17:49:14 +0000 UTCIt's not a Riemann sum, it's an integral. Riemann sums have finite number of rectangles. If it help you understand you can see the integral as the limit of a Reinmann sum as the number of rectangles grow to infinity. The Reimann sum itself will never be exactly equal to the area but its limit will.

2018-06-09 17:38:56 +0000 UTCGuys. it's not a math video. It's a history video. It's not teaching you math it's teaching you math's history. Stop saying that's the best math class you ever had. If you didn't know how to do an integral before watching it you still don't. Now, don't get me wrong it's a great video. You learn context, history, and a lot of useful things. But no math. And not because it fails but because it does not try. Extra History. It's great at what it does which is teaching history.

2018-06-09 05:59:47 +0000 UTCThe Riemann sum made to an infinite degree should approximately equal the area of the circle, not truly equal it. So, the equal sign should be an about equal sign (I am not sure of its official name). I just thought I should print this out.

2018-06-08 21:05:29 +0000 UTCNick has definitely been challenged by the unique requirements of this series and he worked really hard! This made him happy to hear :)

2018-06-08 19:59:02 +0000 UTCWhen the topic was proposed, I did not know it would be one of the most engrossing subjects you all would cover, yet somehow, it is.

2018-06-08 18:15:00 +0000 UTCI have to say, Nick's illustrations and animation styles fit extremely well with this particular series. Geometry's always better to understand when you can see the visualization of the concept. This is already starting to become one of my favorite series you guys have ever done!

2018-06-08 17:58:52 +0000 UTCWish I could have watched this before taking college Calculus. I managed, but it was still annoying how hard it was to relate it to anything I'd done before. I often joke now that learning Calc ruined most of my previous understanding of math.
