Hello from Canada Mr. Wildberger. Your former stomping grounds. 80 cm of snow on the ground outside! I've been following your lectures. Is there a textbook that you use to accompany these differential geometry lectures?
njwildberger Dear professor,What does it mean to say something is Linear ? Can u give me an intuition about something as Linear or bilinear.My proff often say Linear mapping, linear relation , bilinear or it acts in a linear fashion..etc. I know the mathematical definition ,But i wish to get to really know in an intuitive way or the historical way of how /why it was named "Linear"--Can u provide lectuers on Tensor algebra? Is there some tricks to understandd abstract algebra..or Am I less intelligent to learn such hard topics? Do really people think in terms of Abstract way or do they think in normal way and make it abstract so that they want people to think of them as "Intelligent "..:)

I know he has been reading his book Divine Proportions when lecturing. wildegg.com/products.htm. There is a chapter about tangent conics.
You are probably looking forward for some more global warming! Actually there is no textbook that I am following for this course.

Naseefabdurazack Please start watching my WildLinAlg series on Linear Algebra. There you will get a really good understanding of what linear means.
