Is there a good explanation of a manifold on the web somewhere? The wikipedia article isn't really working for me. I was actually hoping for a whiteboard lecture on youtube, but can't find one.
My math experience is calculus through differential equations, twenty five years ago. I also have some computer science related math; discrete structures and numerical methods.
My problem with the Wikipedia article is that I just can't visualize what they're saying.
Any sources (not just web based) are appreciated.
I stumbled upon the Wikipedia article while trying to brush up on my math. I had been talking to my daughter about primes, we wandered there from her 4th grade homework. We ventured as far as Mersene primes and perfect numbers. It was at this point that I knew I had to brush up.
Somehow I chased a link to Riemann manifolds and this was completely new to me.
Having looked at some of the suggested material from the answers, the Wikipedia article makes a lot more sense. In fact I'm trying to figure out why I found it unclear, maybe it can be improved.
