These visions of the future are based in the discoveries of today, as a new science of materials emerges from the elemental building blocks of the universe, promising a future in which we can create virtually anything we want, atom by atom. I'm David Pogue, and I'm on a quest to discover how the world's smallest materials are changing our lives: swarms of nano-machines that combat cancer on the cellular level with bee venom;...

The MIT Department of Physics has been a national resource since the turn of the 20th century. Our Department has been at the center of the revolution in understanding the nature of matter and energy and the dynamics of the cosmos. Our faculty - three of whom hold Nobel Prizes and 21 of whom are members of the National Academy of Sciences - include leaders in nearly every major area of physics. World leaders in science and engineering, including 10 Nobel Prize recipients, have been educated in the physics classrooms and laboratories at MIT.
