Scientist and author Astro Teller is changing the world with his projects at X, Google’s research and development facility. Along with other scientists, he's exploring out-of-this world concepts like wind-powered internet; self-driving cars; and lighter-than-air cargo ships. Believe it or not, the most important part of the research is failure. People don’t have the courage to dream up new ideas if they’re too afraid they’ll fail. Making failure welcome and encouraged is how Teller and the people at X are striving to make this world a wonderful place—and how you can, too.
