The Essence of Science Explained in 63 Seconds
Here it is, in a nutshell: The logic of science boiled down to one, essential idea. It comes from Richard Feynman, one of the great scientists of the 20th century, who wrote it on the blackboard during a class at Cornell in 1964.
Think about what he's saying. Science is our way of describing--as best we can--how the world works. The world, it is presumed, works perfectly well without us. Our thinking about it makes no important difference. It is out there, being the world. We are locked in, busy in our minds. And when our minds make a guess about what's happening out there, if we put our guess to the test, and we don't get the results we expect, as Feynman says, there can be only one conclusion: we're wrong.
The world knows. Our minds guess. In any contest between the two, The World Out There wins. It doesn't matter, Feynman tells the class, "how smart you are, who made the guess, or what his name is, if it disagrees with the experiment, it is wrong."

PODCAST & VIDEO: 3D Printing Replacement Body Parts
Regenerative medicine, a fledgling field with the aim of regrowing parts from a person’s own cells, is being amplified with 3D-printing technology, which can now use organic materials to create scaffolds that cells need to grow into their final forms. Richard Wysk, a professor of industrial and systems engineering at North Carolina State University, discusses the latest successes with this research, and the timeline for creating more complicated structures.
