They are all from TED and I suggest you watch in this order (but watch as you please):
David Merrill: Siftables, the toy blocks that think -
http://www.ted.com/talks/david_merrill_demos_siftables_the_smart_blocks.html
MIT grad student David Merrill demos Siftables -- cookie-sized,
computerized tiles you can stack and shuffle in your hands. These
future-toys can do math, play music, and talk to their friends, too. Is
this the next thing in hands-on learning?
Barry Schwartz: The real crisis? We stopped being wise - http://www.ted.com/talks/barry_schwartz_on_our_loss_of_wisdom.html
DESCRIPTION: Barry Schwartz makes a passionate call for "practical
wisdom" as an antidote to a society gone mad with bureaucracy. He
argues powerfully that rules often fail us, incentives often backfire,
and practical, everyday wisdom will help rebuild our world.
Elizabeth Gilbert: A different way to think about creative genius - http://www.ted.com/talks/elizabeth_gilbert_on_genius.html
DESCRIPTION: Elizabeth Gilbert muses on the impossible things we expect
from artists and geniuses -- and shares the radical idea that, instead
of the rare person "being" a genius, all of us "have" a genius. It's a
funny, personal and surprisingly moving talk.
Jill Bolte Taylor: My stroke of insight -
http://www.ted.com/index.php/talks/jill_bolte_taylor_s_powerful_stroke_of_insight.html
Jill Bolte Taylor got a research opportunity few brain scientists would
wish for: She had a massive stroke, and watched as her brain functions
-- motion, speech, self-awareness -- shut down one by one. An
astonishing story.
Bill Gates: How I'm trying to change the world now - http://www.ted.com/talks/bill_gates_unplugged.html
Bill Gates hopes to solve some of the world's biggest problems using a
new kind of philanthropy. In a passionate and, yes, funny 18 minutes,
he asks us to consider two big questions and how we might answer them.
