Molecules for the masses: App puts chemistry at the tips of users' fingers

Although molecules make up everything around us, most people encounter these groups of atoms held together by chemical bonds in the pages of a textbook. They read text and see a drawing of chemical symbols or colorful circles—a one-dimensional view of the microscopic structures. Other representations have drawbacks as well: three-dimensional models are made of materials that can't replicate the rapid and continuous molecular movement. Molecules are wiggling and jiggling in a never-ending dance
