	John Kerr (physicist) - Wikipedia, the free encyclopedia
		John Kerr (December 17, 1824 – August 15, 1907) was a Scottish physicist who inaugurated the field of electro-optics.
		Kerr's original cell was a glass block while modern cells are more commonly filled with liquids such as nitrobenzene.
		In the Kerr effect, the change in refractive index is proportional to the square of the electric field.

	Theory
		The purpose of this experiment was to measure the transverse and longitudinal magneto-optical Kerr effects for two samples of iron cobalt thin films.
		The magneto-optical Kerr effect is the rotation of polarization that occurs when linearly polarized light is reflected off of the surface of a magnetized sample.
		The longitudinal Kerr effect occurs when the magnetization, M, is parallel to the surface of the sample and in the plane of incidence.

	Kerr Coat of Arms
		The distinguished surname Kerr is a proud example of one of the more noteworthy Scottish surnames.
		The earliest forms of hereditary surnames in Scottish were the patronymic surnames, which are derived from the father's given name, and metronymic surnames, which are derived from the mother's given name.
		The surname Kerr is derived from the Gaelic name O'Ciarain or O'Ceirin,, which itself comes from the Gaelic word ciar, which means fl or dark brown.

		Ever since physicists invented particle accelerators, nearly 80 years ago, they have used them for such exotic tasks as splitting atoms, transmuting elements, producing antimatter and creating particles not previously observed in nature.
		I have never claimed to be a physicist or an expert on what the CERN laboratory is doing at any given moment so I feel it is pointless to argue about what they may be doing in the future or what "breakthroughs" they will or might have.

		Loschmidt's experimental investigations in electromagnetism figure in the prehistory of the work of Edwin Hall, John Kerr, and Heinrich Hertz.
		He undertook experiments to detect the Hall and Kerr effects, and to discover the induction of sparks by electromagnetic waves transmitted from other sparks.
		By contrast, Stefan, Maxwell, Boltzmann, and other leading physicists were very receptive to Loschmidt's determinations of molecular size and mass, and to his later work in physics.

	Kathryn Cramer: Quantum Mechanics: Not Just a Matter of Interpretation
		John Cramer is a physicist at the University of Washington in Seattle, WA.
		Afshar's trick is to find the location of the minimum points of wave interference, place one or more wires at these minimum points, and observe how much light is intercepted when one is determining the pinhole through which the photons passed.
		It has been widely accepted that the rival interpretations of quantum mechanics, e.g., the Copenhagen Interpretation, the Many-Worlds Interpretation, and my father John Cramer's Transactional Interpretation, cannot be distinguished or falsified by experiment, because the experimental predictions come from the formalism that all such interpretations describe.
