Don't know what a TED Talk is? Well then you're going to want to continue reading because they are a great source of information and entertainment and I enjoy watching them very much!
The About section on TED.com explains that "TED is a nonprofit devoted to spreading ideas, usually in the form of short, powerful talks (18 minutes or less). TED began in 1984 as a conference where Technology, Entertainment and Design converged, and today covers almost all topics — from science to business to global issues — in more than 100 languages. Meanwhile, independently run TEDx events help share ideas in communities around the world."
You can also find many TED Talks on YouTube and I encourage you to see what they are all about, I don't think you will be disappointed. Over the next couple of days I will be sharing some of my favorite talks (in no specific order), let me know what you think, or if you are familiar with TED and you have some favorites please share them with me in the comments section!
