James Clerk Maxwell of GlenlairFRS FRSE (13 June 1831 – 5 November 1879) was a Scottishphysicist and mathematician. His most prominent achievement was formulating classical electromagnetic theory. This unites all previously unrelated observations, experiments, and equations of electricity, magnetism, and optics into a consistent theory.Maxwell's equations demonstrate that electricity, magnetism and light are all manifestations of the same phenomenon, namely the electromagnetic field. Subsequently, all other classic laws or equations of these disciplines became simplified cases of Maxwell's equations. Maxwell's achievements concerning electromagnetism have been called the "second great unification in physics", after the first one realised by Isaac Newton.

Maxwell demonstrated that electric and magnetic fields travel through space in the form of waves and at the constant speed of light. In 1865, Maxwell published A Dynamical Theory of the Electromagnetic Field. It was with this that he first proposed that light was in fact undulations in the same medium that is the cause of electric and magnetic phenomena. His work in producing a unified model of electromagnetism is one of the greatest advances in physics.

Peter Achinstein (30 June 1935, New York) is a distinguished American Philosopher of Science. He is the author of numerous influential books and articles. He is the Jay and Jeanie Schottenstein University Professor of Philosophy at Yeshiva University, director of the Yeshiva Center for History and Philosophy of Science, and a professor at Johns Hopkins University.

Achinstein received his B.A. and Ph.D. from Harvard. He specializes in philosophy of science with strong interests in the history of science.

Achinstein has taught for many years at Johns Hopkins University, where he is currently Professor of Philosophy. In Spring 2009, Achinstein began teaching at Yeshiva University as the Jay and Jeanie Schottenstein University Professor of Philosophy and is the founder and director of the Center for History and Philosophy of Science of Yeshiva University, New York. He returned to Johns Hopkins in Spring 2011. He has held Guggenheim, NEH, and NSF fellowships, and has served as a visiting professor at MIT, Stanford, and the Hebrew University of Jerusalem.

"The Man" is a slang phrase that may refer to the government or to some other authority in a position of power. In addition to this derogatory connotation, it may also serve as a term of respect and praise.

The phrase "the Man is keeping me down" is commonly used to describe oppression. The phrase "stick it to the Man" encourages resistance to authority, and essentially means "fight back" or "resist", either openly or via sabotage.

The earliest recorded use^{[citation needed]} of the term "the Man" in the American sense dates back to a letter written by a young Alexander Hamilton in September 1772, when he was 15. In a letter to his father James Hamilton, published in the Royal Dutch-American Gazette, he described the response of the Dutch governor of St. Croix to a hurricane that raked that island on August 31, 1772. "Our General has issued several very salutary and humane regulations and both in his publick and private measures, has shewn himself the Man." ^{[dubious – discuss]} In the Southern U.S. states, the phrase came to be applied to any man or any group in a position of authority, or to authority in the abstract. From about the 1950s the phrase was also an underworld code word for police, the warden of a prison or other law enforcement or penal authorities.
