The Discovery Channel and AOL are using a scientific method to determine who exactly is the Greatest American of All Time: They're taking an online poll, of course.
It's narrowed down to 100, so now each candidate is going to be profiled in a four-part weekly show. But no purchase is necessary. You can see the candidates and voice your opinions on Discovery's blog.
Among the nominees that might interest NanoBot readers:
Alexander Graham Bell, Thomas Edison, Albert Einstein, Benjamin Franklin, Bill Gates, Orville and Wilbur Wright, Jonas Salk, Carl Sagan and, of course, Tom Cruise ("Minority Report" featured some cool nano.)
