Text errata:
Page 255, 4th line under Particulates: I would prefer the definitions of particulates and aerosols given on page 250: particulates are solids suspended in air; aerosols are droplets of liquid suspended in air.
Page 274, 7th line under Settling chamber paragraph: In the statement of the analogy of the masses on a spinning record, the result is incorrect. The order in which an object is thrown off a spinning disk is independent of the mass of the object. The order does depend upon the characteristics of the surfaces of the object and the disk (the maximum coefficient of static friction).
