The Science of Everything - David Pogue

There are scientific laws and principles at play in nearly every invention that makes the world tick: washing machines apply Newton's First Law of Motion, GPS uses any three of 24 satellites installed by the U.S. government to triangulate locations on earth, and aluminum was once a rare, valuable element. Science writer David Pogue discusses National Geographic's new book, The Science of Everything, which breaks down the underlying science that might not seem obvious, but is necessary for many of the modern comforts to which we've grown accustomed.
