I really don’t know why some silly people dislike Khan academy’s videos Either they lack sense to understand anything or they become mad by seeing that khan academy provide free education to everyone and helps us to understand easily Seriously they are too bad My heart got broken when I saw that there 13 dislikes only on 143 likes 😭😭😫😫😖😣

Don’t worry, it’s the KZbin’s algorithm that cause some people to dislike the video.

No skeptic, this man has deep understanding of physics.

wow, thanks, super clear and concise presentation. I finally get the reason for making up a derivative quantity like 1/(focal length), the adding of powers (also that no correction = 0 diopters instead of infinite focal length).

Sketchbook, a freeware, for writing and Camtasia studios, a non-freeware, for screen capture and editing.
