Your sense of humor really helps to learn!!

I am about a year into my studies for ABO certification. I chose to self teach while working through a two year apprenticeship. You have no idea how enormously helpful these videos are. Thank you for all the material.

thank you doctor barney Stinson. ....you're awesome

This was another fantastic video. Subscribed. I'm not sure it answered my question about odd concave rays, but I still learned something. :) Thank you for your help.

All students are advised to clear their doubts by these videos.

Wow. Thank you. I'm pretty busy, though. What kind of commitment are you thinking?

Well, shoot. I'll address it directly, then! I draw only principal rays to prevent clutter. The curved mirror should be viewed as a plane mirror for every single ray that you choose to draw (incoming and outgoing angles away from the normal to the surface equal). The only difference from the curve is that the normal to the surface is NOT always parallel to the principle axis. Thanks for bearing with me.

I love the "turn your head pi/2" note

I see! That makes more sense now. You had mentioned that in one of your videos but it didn't quite click until after watching this video, so in the end it did help! :) What I'm really trying to understand is some complex philosophical thought problems I'm coming up with to explain the creation of the universe using spherical lenses and mirrors in weird combinations. I wonder if you're available to answer complex questions for a fee?

thanks a lot doc keep goinng ♥️

If only I had you as my physics teacher

thank you Doctor..

Hello, I have a question regarding the rays coming from the flower. The ray that you drew perpendicularly from the flower to the Mirror doesn't reach Newton's eye, right? But then you extended it to the back of the mirror and Newton is able to see the flower. So basically, it doesn't matter if the reflected rays from the mirror reach the eye or not? Because the rays are extended behind the mirror and Newton is able to see the image anyway? Is that how it works? Both the rays that reach his eye and the rays that don't reach his eye contribute to the formation of the image behind the mirror?

Genius

Maybe the image in the Mirror is real tho 😲

9:18 hahahahhahaha

There's a tiny mistake bout the flower lol --because all numbers of petals from a flower should be a term in a Fibonacci Sequence~ and 7 is not from the sequence...

You should read. Goodbye.
