June 18 Chemistry class

Majority students of this class will take Physics / AP Physics next school year ( survey result at our 06/11 class).  In the class meet on 06/18, I will teach contents of interface of high school Physics and Chemistry, including Wave Properties of Matter, Atomic Spectra, etc.

The division between chemistry and physics melds at their interface where the extrinsic and intrinsic systems of matter combine, notably in such fields as physical chemistry (my  Ph.D. is in physical chemistry), chemical physics, quantum mechanics, nuclear physics/chemistry, materials science, spectroscopy, solid state physics, solid-state chemistry, crystallography, and nanotechnology.

Marie Curie is the only individual to be awarded Nobel Prizes in both chemistry and physics.
