I love watching documentaries on any topic, especially if they are about architecture and design, but I especially love those short documentaries that in a short time expose something incredible; there are no better than TED talks. 

TED is an American media organization that publishes talks online for free distribution under the slogan "ideas worth spreading".

"TED" stands for Technology, Entertainment and Design, three major areas that together are shaping our future, although in reality the event includes many more topics, showcasing "ideas worth spreading" from any discipline. 

The interesting thing about this platform is that it allows you to watch, online, and for free, millions of talks on the most diverse topics. The event has been held in hundreds of countries, and people who have an interesting idea, a project to show, about art, psychology, physics, or any topic you choose, are invited to exhibit.

If you are interested in learning, TED is the best option.
