Merriam Webster’s dictionary defines ‘genius’ as a person who exhibits “extraordinary intellectual power, especially as manifested in creative activity.” These great innovators fill the pages of our history books with their creative exploits, but what about a modern day genius?

When searching for a recent example, to us the quintessential genius of the 20th and 21st centuries is Bill Gates. A man who has not only influenced and revolutionized the technology industry, but has creatively charged the world with his philanthropy and ideas.

In this lengthy, but poignant, TEDTalk, we’re able to get a glimpse inside the brain of one of the most successful men in the world, but not about his business or his charity. Bill Gates’ genius lies in the fact that he is a problem-solver; he innovates no matter what he does, and his new passion is helping solve our energy crisis.

Bill Gates, and this Talk in particular, perfectly embodies the core of what TED is: innovators getting together, sharing ideas worth spreading, and changing the world.
