You are at least an order of magnitude clearer, more interesting, and more enthusiastic than my physics professor. Thank you for these videos!

Absolutely love how animated you are! Keeps me paying attention, thanks!

Thank you for actually making physics fun to learn. I was falling asleep studying for my final and this video actually made me laugh and learn. I never thought I could find physics this entertaining.

you've taught me everything i have done for a month in this video, thank you so much!

The best Physics teacher that I had came across ;)

I really love ur mode of teaching which makes Physics not a hard,boring subject but the easiest one.U have really inspired me to read Physics throughout my life.Thanks a lot from BD.

Upbeat, rational, understandable, an excellent source.

Thankyou so much man, saved me at the eleventh hour

I love how his teaching is so raw. He makes the same errors we all would doing this for the first time, and exhibits the type of calm, rational thinking that yealed great results!!!!

I had a short quiz last week. I aced it, thank you sir. You're awesome 😁

This teacher is too good to be true

very entertaining to watch. I used to be TERRIFIED of lenses and mirrors in physics

such a great teacher ☺️ I was in tears at 4:30😂

You should get the prize of the best teacher in the world 🌸 . So much fun to watch your videos though I am a MS physics student 😅

I have a science exam this morning so this helps! thanks! ^^

going to have the exam soon! thanks for all the vid!

I am loocking for the 5 of 5 video . . . Thanks, very good your videos ...

By the way, the unlikely result at 4:30 is due to inaccuracy in spotting the focal points to be at the same distance from the lense axes

Thank you so much !!!

meep help please. What happens when you have to draw a graph where you don't know how high the object is or where you should be drawing the eye/source of light?

Excellentttttttt

doc, is the formula for mirros and lens the same?

Thank you sir

THANK YOUUUUUUU!!

very nice

if the image is formed at near point then where is the object placed?

Too good Sir! Keep it up!

This is awesome ahahahaha (also, at 1.5x speed it's even better)

I gotta learn this cause I'm lost in our current lesson

This in geogebra: geogebra.org/m/pt2t2deh So that you can play with it and see what happens.

very helpful and presented in a fun way

Lol you ALWAYS forget the line of action😂

Is there a C ray with this type of lens?

this guy is funny i like him

Ahahha you keep saying mirror for lens! XD But great video!

THANK YOU SO MUCH!! sorry for the caps spam, but i was so lost with this, as it is my optional and had to study it in alone with just a book. This was really helpful and interesting thank you :)

Damnn nighas good at teachin and funny tho

Yo

He sounds like Ryan Reynolds, do you agree?

Your voice sounds like an older Cole sprouse😂

Thank you so much!
