The Course • Physics, chemistry, and engineering all deal with the same topic… – The functioning of the universe • But, each discipline deals with the functioning of the universe in a different way. 4
Background image of page 4
The Course • Physics is concerned with mathematically describing how the universe functions. – Conservation laws: momentum, energy – Fundamental interactions: Strong, Weak, Electromagnetic, Gravitational • Physicists start by seeking to understand very simple idealized systems so as to deduce general principles. 5

The Course • A chemist examines the universe using a different technique. – A chemist works with a large set of heuristic laws (laws that provide aid or direction in the solution of a problem but are incapable of justification) and develops an encyclopedic knowledge of the behavior of chemicals. –B lack Box
