When it comes to online sources, it is always hard to decide which ones to use. There are plenty websites with useful information on almost all topics. The website I find interesting and use it myself is TED talks.
TED which stands for Technology, Entertainment, Design runs under the slogan “Ideas Worth Spreading” and is an online conference website. It was discovered by architect and graphic designer Richard Saul Wurman in 1984. He observed convergence in technology, entertainment and design therefore its name.
The talks address a wide range of topics from science, research, culture as well as on media. The speakers are given 18 minutes to deliver the speech in the most interesting way. Some of the speakers include Bill Gates, Google founders Larry Page and Sergey Brin and also many Nobel Prize winners.
No matter in what subject you are interested in there is something for everyone. Furthermore, the talks are free, you can watch them from home, on your flight or your daily commute to work. They are easy to access either from ted.com or on their YouTube channel. You can choose from the most popular ones or browse through different topics or type the subject you are interested in in the search bar. Moreover, they offer subtitles in many languages, which makes it convenient and appeals to a wider audience.
I personally highly recommend it and if you have not used it yet, give it a try!
