I enjoyed a lot of good speeches and excellent talks from TED (Technology, Entertainment, Design) for years, and I think it is a sites many readers would enjoy!

Here are some talks that set me thinking on various issues lately:
Peter Saul: Let’s talk about dying
http://www.ted.com/talks/peter_saul_let_s_talk_about_dying.html
To talk about end-of-life wishes is not easy, yet Dr Peter Saul an ICU Specialist from Newcastle, Australia, have a profound talk on the topic and introduce the concept "occupy death".
Ayah Bdeir: Building blocks that blink, beep and teach
http://www.ted.com/talks/ayah_bdeir_building_blocks_that_blink_beep_and_teach.html
"Imagine a set of electronics as easy to play with as Legos. Ayah Bdeir introduces littleBits, a set of simple, interchangeable blocks that make programming as simple and important a part of creativity as snapping blocks together"
It is like a growing library, and I know a growing library will work in a creative way beyond our imagination!
Martin Jacques: Understanding the rise of China
http://www.youtube.com/watch?v=imhUmLtlZpw
"Speaking at a TED Salon in London, economist Martin Jacques asks: How do we in the West make sense of China and its phenomenal rise? The author of "When China Rules the World," he examines why the West often puzzles over the growing power of the Chinese economy, and offers three building blocks for understanding what China is and will become."
