  • When did you prove that h is a constant?

  • @yoshioua that is just the angular moment conservation

  • key word: "wasn't as mathematically as vigorious as I wanted". There you go! He's just showing off his math prowess. Go elsewhere.

  • @thoumaturgica Whatever Dude! Thats something bolster! I wish I could be that excited when I do math. He's a badass!

  • Kepler was a genius! Especially considering he lived in the 17th century. He was a mathematician, astronomer, and perhaps suprisingly an astrologer.

  • i didnt understand a word...mostly cuz of that accent

  • keppler stole most of it.

  • You are great! I enjoyed this proof very much. Do you teach somewhere, or offer tutoring?

  • Very interesting teaching style but it paid off. Everything you said made perfect sense and it's understandable. Congratulations. Excellent job, without a shadow of a doubt.

  • Man I'm so high right now. I've GOT to find that equation. I'm eliminating the time right now.

  • Donylee, do you mind posting more videos regarding subjects on mathematical astronomy. Recently, I am interested in knowing on calculating the period duration of a total lunar solar eclipese. Thank you!

  • Hi Donylee, I got a question here. You applied Newton's inverse square law F=Gm1m2/r2 here and may I know how Newton derived this equation using mathematics in the first place. Thanks for your video, it is really great.

  • in layman's terms, please, why are the two hemispheres of an orbital ellipse equal? why not an egg shape?

  • The Bruce Lee of math.....Asians are Freakin smart!!Good job!!!

  • That is one of the top complements I have heard thus far from my viewers. 'Bruce Lee of Math', I like it!

    I must humbly saw that while I am proud to be Asian, I am still very from the league of Nobel Laureates and Field Medalists, whom I believe are mostly from US and Europe.

  • 'my secret little formula' ... evil laugh now ^^

  • Huh? I didn't quite get that. It's really Kepler's formula, not mind.

  • @donylee He is referring to in your video at around 8:02, when you said it. Great Video!

  • Just curious. Is it fine to leave the differential quantity 'rate of change of angle' in the equation of motion on the left, eventhough it may mean nothing.

  • Hello teezie07,

    That's for your interest in Gaussian math. I get what you mean. It's somewhat inaccurate to say that the differential quantity 'rate of change of angle' means nothing. In fact, that is what it exactly means though irrelevant to the problem.

    We have left it there because, this quantity whatever it may be, will be substitute later with the equation on the right to progress towards the solution.
