thanx 2 to autoplay i am enjoying series...dunno how many yet to see....great presentation...very explanatory no insult 2 intellect, great humor, exciting & informative demonstrations...rock on mr. n mrs. rojas (sp?)
-
that was coo
-
Tip: use smoke to make light paths visible. It does not go away as quickly as water spray, and it wil not affect the lens/mirror surfaces.
-
great demonstration man!
-
if you put the fresnel lens in between the mirrorwill it make that bat man brighter?
-
its explained in detail in the standard physics II class. just look up lenses/mirrors and refraction and whatnot
you can even calculate the curvature required of a mirror so that an object behind the mirror looks like its closer to you than the lens itself
:) enjoy

This video is fantastic. Best video of its kind. I read the book for hours and it didn't really click until I watched this video. I'm self studying physics so I don't have a teacher or lecturer or other students to ask questions when I don't understand something.This stuff is brilliant. You are now my new physics teacher.

You would make a good science teacher, and I wouldn't be bored at all. I'm a professional photographer and you've taught me more about Focal Length than I ever understood in photography class, honestly.
