When you hear the word creative you don't necessarily think of science. But science is an extremely creative process and has occupied some of the most creative thinkers in human history. Many of the problems in the world can be solved by science, such as rising energy costs, global warming, starvation, and disease.
Admittedly, the following video was made for corporate propaganda purposes, but it does a beautiful job of illustrating why science is an alluring, creative field with the mission to change the world.
I am a scientist because I love the thrill of creatively solving a difficult problem. The prospect that in some small way my work might change the world for the better turns a fun career into a great one.
And of course, nothing says science like Asians in lab coats. :D
