Your videos are a great help and and a joy to watch. You present information in a straight-forward and easily understandable way, while keeping the viewer interested and involved. I'm reviewing for a college entrance exam with your videos as my guide, and thanks to your work, I'm confident I will do well. Thank you, thank you, thank you!

How did it go with the tech awards?

Utterly. Thoroughly. Admirable!
I'm genuflecting like the friggin' Fist of The North Star here!
Consider yourself highly appreciated and respected by this one!
The world is greedy and treacherous and hampered by so many things, and people like you are the shining ray that pierces the darkness and keeps the spirit of the betterment of mankind alive.
This might sound sappy, but I don't care, Math is tremendous power and We can (virtually) parametrize anything, which allows us to eventually unlock more knowledge to share!
Knowledge like this, should always be free for anyone, since it, in my humble opinion, can only help us in the long run.
Again, I bow to you, good Sir!
Many thanks, and keep up the good work!
Cheers!

keep on rockin sir dude \m/

One of the best youtube channels, thanks Mr Khan!!

Thank you mr. Khan! I am participating with the EUSO(European union science Olympiad), and I'm going to the dutch nationals! But physics is my weakest subject, and luckily you have more than 100 videos about it :) Thanks!
