Check out this great talk “How I’m trying to change the world now” by Bill Gates at TED. He brought few mosquitoes (of course, not infected) with him and let them roam around the auditorium. He questioned why only poor people should have this experience.

My favorite quote from this talk:

“I am an optimist. Any tough problems I think can be solved” – Bill Gates, Feb 2009

He talks about couple of problems during this talk:

  1. How do you stop a deadly disease that’s spread by  mosquitoes? (Hence the mosquitoes visit to the auditorium)
  2. How do you make a teacher great?

Great talk!
