“It is not knowledge, but the act of learning, not possession but the act of getting there, which grants the greatest enjoyment.” —Carl Friedrich Gauss
"If teaching is reduced to mere data transmission, if there is no sharing of excitement and wonder, if teachers themselves are passive recipients of information and not creators of new ideas, what hope is there for their students?" —Paul Lockhart, A Mathematician's Lament: www.maa.org/external_archive/devlin/LockhartsLament.pdf
Haha, yes indeed. There are a lot of different channels, but they seem to be hard to find. Also, Steven Strogatz lectures are a gem, but I could only find them on YouTube ... I would've expected that a University (Cornell or MIT) would've opened up all their resources about the course.
