  1.  @atomictraveller  There are plenty of baseball, basketball, and football players who never took physics or engineering, but their muscles know how to make a projectile follow the ballistic path they want or how much spin to put on a ball to make it stay in the air or curve away from the batter at the right time. Either way it takes a lot of study, but it depends on how you want to apply it.

  2. Mmmmmm pie!

  3.  @atomictraveller  You actually do use e. It is the inverse of the natural logarithmic function (Ln). Perhaps you only deal with Ln, but e is related to what you do.

  4. Good for you! He does make it fascinating!

  5. Mmmmmm pi(e) 🤪

  6. Also, thanks for your expertise. You're right. It's all related, but I think math and science are better at describing things that exist rather than create new ideas and pieces.

  7. Elegant! I love these videos because they are about my comprehension and beyond. Were I to take up mathematics in my spare time and study it beyond the necessary cramming to pass university classes, I will already have been exposed to these higher mathematical concepts. Exposure is the first step to go from clueless to mastership, so I have that first advantage. Thank you for going beyond the Maths concepts that many instructors stop at (i.e. Algebra).

  8. Can you illustrate how the long division of square roots works? Why are some digits doubled?

  9. Maybe that's um... Maybe that's enough for today. 😊

  10. Smoothe!

  11. All the "flowers" that descend to the middle reflect back out to the circle perimeter! Wicked! Like a previous poster said, math is trippy!

  12. In geometry in high school, the first few lessons were to teach us that a proof can be done using complete nonsense as long as you can infer stuff from your axioms. In these chapters, the first group corresponded by mapping one of the widgets called "evitans" to 2 "edobas" and each edoba accommodates up to 3 evitans. Pure nonsense. I could map 4 of one to 4 of see other. But when they said prove six of the first map to 4 of the other, I gave up. Nothing made sense. Not even reversing the names to "native" and "abode." I looked at the next page and saw a diagram of 4 points mapped to 6 lines (4 that made a square and 2 diagonals that crossed) Now it all made sense. Why didn't they do that to begin with? I guess that's also a lesson to teachers to make their subjects eminently accessible by bringing up real - life examples.

  13. Maybe not with straightedge and compass, but it seems like I've come very close to trisecting an angle with origami folds! I have seen it emerge from folding patterns numerous times. But I am sure you would find some way of breaking that down as a pure mathematician could.

  14. At least if trying to trisect an angle with origami is a useless pursuit, I would have a pretty figure when I finish. 😉

  15. I like seeing true - life projects emerge from classroom activities. I expect to see a lot of creative flourishing happening as this pandemic turns us inside out.

  16. FINGER PROOF! 👍👏

  17. What's nice about these videos is that I don't have to take notes anymore. I can just watch as the concepts unfold! And I can re-watch it as I please.

  19. Okay. I saw a video about how there is no formula to do anything more than approximate the perimeter of an ellipse. I think it's bull cookies. How could Apollo get to the Moon if all you could do was estimate where the Earth and Moon were? Please tell me there really is a way of getting the exact perimeter of an ellipse. Please save the astronauts.

  20. Are Neptune and Pluto a double planet system?

  21. Oops! You meant to say the square of i is -1 to Homer, I'm sure, not 1.

  22. Zeroes of arbitrary length?!

  23.  @alapandas6398  New Angle System? 😉Tom Lehrer! Where are you when we need you!

  24. How much of higher mathematics is proof by contradiction?

  25. Yeah! Why DIDN'T they teach this in my college Calculus? Neither Calculus for non - engineers nor Calculus for engineers had this!

  26. Where the blazes did Madhuva get 355/113 ?! Unless that corresponds to a trait of pi, that's just pulling a random number out of the proverbial backside. So unless he proved all mathematical roads lead to pi, I ain't buying it. The proof is all bogus unless there is at least some demonstration of pi connection. Otherwise it's pretty pictures of "mentable gymnasticals" As Walt Kelly's character Pogo would call it. (actually, I think it was Albert Alligator)

  27. I did not learn this in public school (USA). As I was a Biology major in university, I did not learn it there, either, nor in my Education Master's degree (MAT). The farthest I got was engineering analysis for 3 semesters —i.e. Calculus for engineers. I was about to take Linear Equations when my money ran out and I had to leave university. 😔 But I love math! And these lectures are excellent for me to stretch my brain! I'm going to try the sqrt2+sqrt3 = pi

  28. Oh, and how does ANYONE do this kind of math with any speed besides using pencil and paper?!

  29. Why couldn't my math teachers have shown us some of these beautiful visual proofs!?! Ah! If the Internet were only available in 1977 like it is today! I'd look up these proofs and be amazed but more completely enlightened at how simple and elegant they are! 💜

  30. Yes. I've seen all these mathematical proofs in high school. The arguments are as airtight as you can get them. But I always still felt that there was infinitesimal cheating and adding of an additional tiny magnitude with the digit 9 appearing out of nowhere. My brain is way too finite to grasp the size of infinity, but I've seen manipulations of infinity and axioms of "different kinds of infinity." That confused me to no end. But I must sigh and accept this all as true because of extensive testing on it. Maybe in Paradise the infinite fraction is conceivable.

  31. In the last picture, phi is crossing over several of the hurricane spirals. So it is completely off!
