"Although it’s already well known that we should pace our studies, new research suggests that we should aim for “minimal interference” during these breaks – deliberately avoiding any activity that could tamper with the delicate task of memory formation. So no running errands, checking your emails, or surfing the web on your smartphone. You really need to give your brain the chance for a complete recharge with no distractions."
“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
