I'm trying out different videos and I can't find ANY instructional content in them - I mean in terms of technical information, something applied that you can learn and use. It feels like watching a TED talk and not a Khan academy lecture!

I just watched the first two sequences of videos and so far they have shown how to compute midpoints of lines and how to compute the coordinates of points on parabolic arcs given three arbitrary control points, including how to prove the identities involved. They then explain how this is used in practice to generate the shape of a blade of grass. Is this not the kind of technical information you were expecting to find?

I guess it would be great if there was some sort of application that let you apply these techniques and actually see the results.

Otherwise, it's like reading the theory section of documentation without getting to use the program.

All of our lessons give you interactive tools to create and experiment with in various ways. For example this one is fun: https://www.khanacademy.org/partner-content/pixar/modeling-c...

Yeah, I take my criticism back.

I didn't go through the whole thing initially. Excellent examples.

Thanks for your hard work. It is indeed an amazing series.
