Continuing to take readers on a uniquely accessible journey through physics, Superstrings and Other Things: A Guide to Physics, Third Edition, explains the basic concepts of motion, energy, and gravity, right up to the latest theories about the structure of matter, the origin and structure of the universe, and the beginning of time. Fully updated throughout, this book explores major historical discoveries and the scientists behind them. In addition, this comprehensive text details the breathtaking frontiers of physics being explored today. Offering nonscience students access to the highest peaks of physics, Dr.
In physics , string theory    is a theoretical framework in which the point-like particles of particle physics are replaced by one-dimensional objects called strings. String theory describes how these strings propagate through space and interact with each other. On distance scales larger than the string scale, a string looks just like an ordinary particle, with its mass , charge , and other properties determined by the vibrational state of the string. In string theory, one of the many vibrational states of the string corresponds to the graviton , a quantum mechanical particle that carries gravitational force. Thus string theory is a theory of quantum gravity. String theory is a broad and varied subject that attempts to address a number of deep questions of fundamental physics. String theory has contributed a number of advances to mathematical physics , which have been applied to a variety of problems in black hole physics, early universe cosmology , nuclear physics , and condensed matter physics , and it has stimulated a number of major developments in pure mathematics.
December 11, When someone mentions "different dimensions," we tend to think of things like parallel universes — alternate realities that exist parallel to our own, but where things work or happened differently. However, the reality of dimensions and how they play a role in the ordering of our Universe is really quite different from this popular characterization. To break it down, dimensions are simply the different facets of what we perceive to be reality. We are immediately aware of the three dimensions that surround us on a daily basis — those that define the length, width, and depth of all objects in our universes the x, y, and z axes, respectively. Beyond these three visible dimensions, scientists believe that there may be many more.
