Conceptual Physics Alive: Atoms

Conceptual Physics Alive: Atoms includes a digital video and questions set with answers. Observe Paul Hewitt teach in a classroom with real students, using engaging demonstrations and artwork. In this video, Bohr's atomic model is described, with emphasis on the smallness, emptiness, and plentifulness of atoms. Atomic number, atomic mass, relative atomic sizes, and the wave properties of matter are also discussed.

Consequences of the smallness of helium and fluorine. Diagram and description of various atoms. Empty space of atoms. Neutrinos and their incidence upon us. Notion of touching at atomic level. Appearance of atoms. Analogy of water diffraction to diffraction of light waves. Electron microscopes and tunneling microscopes. Brownian motion. Comparison of atomic size to humans and the sun.
