I'm sure many of you have seen TED talks, so I though it would be a good idea to create a thread so people can post their favourite ones. For those who don't know what the TED talks are, they're basically a series of lectures from conferences that address a wide range of topics; including technology, entertainment, science, mind-blasting physics, and global issues. I find that they're a great way to procrastinate, and a good use of study breaks.
Here are a few I watched recently:
