Mallett This is the dramatic and inspirational first-person story of theoretical physicist Dr. Ronald Mallett, who recently discovered the basic equations for a working time machine that he believes can be used as a transport vehicle to the past. Combining elements of Rocket Boys and Elegant Universe, Time Traveler follows Mallett's discovery of Einstein's work on space-time, his study of Godel's work on a solution of Einstein's equation that might allow for time travel, and his own research in theoretical physics spanning 30 years that culminated in his recent discovery of the effects of circulating laser light and its application to time travel.

The hyperplane formalism previously employed undergoes a natural generalization in this case to a spacelike hypersphere formalism. In the analysis of the underlying geometry, the minimal pseudo-Euclidean embedding space for the de Sitter universe plays a dominant role and suggests an intrinsic coordinate system of special interest for the representation of geodesics. The de Sitter analogs of the Minkowski space center of energy, center of spin, and center of inertia are constructed, and we find that de Sitter-center of spin to retain commuting components in our intrinsic coordinate system.

It is further shown that this gravitational Faraday effect shares many of the properties of the standard electromagnetic Faraday effect. An experimental arrangement is then suggested for the observation of this gravitational Faraday effect induced by the ring laser. KEY WORDS: general relativity; gravitation; lasers; Maxwell’s equations; Faraday effect.

Devastated, he found solace in the science fiction of H.G. Wells, believing that if he could build a time machine, he could go back into the past, warn his father and perhaps save his life. Ronald Mallett is now a professor of theoretical physics. Remarkably, this working-class African American boy from the Bronx stuck with his vision, overcoming poverty and prejudice in the pursuit of his obsession. This is the story of his extraordinary journey of self- and scientific discovery. With simple language and elegant metaphor he lays out his theories and presents the reader with what is an actual blue print for a time machine. A dramatic and compelling memoir, it is also a brilliant introduction to a riveting but generally baffling subject, and a truly inspirational account of astonishing achievement.

It is shown that this leads to a wavefunction of the universe with a conserved current and a positive-definite probability density.

The particles are therefore expected to condense into a degenerate Bose-Einstein gas, providing a potential candidate for nonbaryonic nonluminous matter.

In addition, Huang neglects to mention an alternative method of calculating quantum effects of this type, which leads to results in agreement with the classical model.

The general relativistic spin equations are then used to study the behavior of a massive spinning neutral particle at the center of the ring laser. It is found that the particle exhibits the phenomenon known as inertial frame-dragging. q
