If you haven't already, go visit the TED website. It is the best thing about the internet. Top minds in all fields demonstrate and speak on such profound topics.
While growing up, what things did you hope to see come to fruition one day? I wanted to see people's faces displayed on phones. Check. Flying cars like the Jetson's. Not yet affordable for me, but for some of you perhaps. Check. Lastly, I want to see the discovery of extraterrestrials amongst us.
Watch this short film about past and future discoveries, but go to TED for the rest of the story. So thought provoking and wonderful.
