I like how you elaborate the information on ellipse, the T^2=a^3 only got typo. Great explanation sir. Thanks 👍

You are welcome! Glad it was helpful.

I like your presentation - well organized, clear and easy to follow. A typo @ 14:20, should be T^2 proportionate to a^3.

I kayaked from Vedbeg to Tycho Brahe's observatory Uraniborg on the island of Hven. Taking your time to travel to locations of scientific importance, allowed me to think about how somebody was wise enough to formulate the questions that led to our understanding of gravity, eliptical orbits and the universe. It is always the quest/question that is the seed to progress, rather than the answer. When the right questions are asked, scientific progress will follow. If progress has been lacking, persevere in reformulating your questions and challenge the '99% of experts agree' argument, brandished by people who never met an expert, never studied the subject and never took the trouble to get into a kayak to learn.

Why use 2*Pi*r when we are dealing with ellipses? Don't get it.

You should consider doing a video that is targeted to those who don't need another elementary explanation of orbits. There are plenty of Kepler videos but they all say the same thing.

Yes, that is true and 2,000 years before Copernicus. I should have said that in the video.

Actually, Kepler hypothesized that the planets moved in elliptical path. He wrote a letter to new asking the question about the path of planets..." If a body moves about another with regard to an inverse square field what would be the path. Newton said ellipse of course and that he proved it mathematical some 20 years prior.... Kepler saw the information in data but his mathematical prowess with polar mathematical forms was not good enough to mathematically prove the path of planets....Thank Newton for that....m
