I never heard of the website TED before, so I took a look. Interesting. Searching on the terms "investing" and "finance" turned up a number of items. Did you try clicking on the magnifying glass at the top right of each page?
A whole new world has just opened up for you! TED talks are brilliant - it's rare that you'll find experts in their field give such concise and interesting overviews of their latest work. Plus, it'll no doubt trigger further reading/research, which is always good. Just as an aside, I like to get exposure to topics which on the face of it don't seem to have anything to do with investing, but actually have weird underlying lessons that apply to the markets and trading. Crowd psychology is something that can inform your understanding of how other people respond to market movements, and give you a chance to second guess what will happen given certain conditions.
