This module traces the controversy over time, from Isaac Newton's "corpuscle" (particle) theory, which prevailed for centuries, to Thomas Young's groundbreaking double slit experiment, which provided evidence that light traveled in waves. This means that heat can have a Joule of energy, but can’t be measured in Newtons. Dissertation Advisor: Professor David Charbonneau Elisabeth R. In order to detect the particles, the chamber is filled with a supersaturated vapor of water or alcohol. The prefix ferro-refers to iron, because permanent magnetism was first observed in lodestone, a form of natural iron ore called magnetite, Fe 3 O 4.
