The world of reality has its limits; the world of imagination is boundless. - Jean Jacques Rousseau
We say "a picture is worth a thousand words" and then ask our students to imagine things they cannot see.
In chemistry, we show two-dimensional representations of atoms, create crude drawings of molecules on classroom boards, and use abstract notations to show where the electrons are. We constantly look for videos - some better than others - to show things and processes so small terms such as "nanotechnology" were invented to classify them. As technology miniaturization becomes more extensive the understanding of it becomes more paramount. But how can we make learning of such concepts more real, more vivid, and more effective?
