Hey Man great videos but in this particular one I wish you explained a bit better (graphically) what ^e1 and ^e2 are. You lost me at the beginning and it was hard to catch up.
@jfaller4454 sorry I went quickly! I always get too excited when recording mathematics! I will try my best to slow down! Can you guess the most frequent comment on my student evaluations? “The guy flys! He gets too excited!”
can you explain what is meant by hat(e1) and hat(e2)? Does hat(e1) just describe the coordinates of the circle around the sun, parametrized in theta while hat(e2) is always orthogonal to it?
Sure thing! e_1 =(cos theta, sin theta) is the unit radial vector and measures the angle between the line segment from the origin and the particle. It changes over time. The hat simply means it is a unit vector. e_2 (hat) is the unit vector orthogonal to this to form a basis! Since the force is radial, only the e_1 component is non-zero!
Easy, you can do that yourself. Take some marker and write something so that is visible on the other side. You will make a glass board from the paper. Then take a picture of the see through side with your phone, and flip the image horizontally. That's why Mike appears lefty in the video. He really is right handed... Unless he is and writes everything backwards on the spot xD
I subscribed as soon as I saw the glass writing board, I love it
@piotr5432 Thanks! Any video requests? I am filming tomorrow!
Can you make a lectures for Electronics and communication engineering?

Excellent 👌🏻
@juancarlossanchezveana1812 Thank you!
can you pls explain to me the sorcery you are doing while writing like are you writing backwards or what just tell me !
he writes normally and flips the frame of video in post
Thanks! @@kanchannegi3476
@kanchannegi3476 is right! I have the camera mirror the image!
