The Elementary Particles:
An overview of the elementary particles, their properties, and the quantum-mechanical laws that govern them.
Special and General
A look at the development and implications of Einstein's most famous idea.
The Uncertainty Principle:
The basic tenet of quantum mechanics, examined logically and comprehensively.
A peek into the exciting and controversial world of wormholes connecting vastly separated regions of space or even parallel universes.
Look beyond Euclid and Pythagoras to the world of shapes in higher dimensions.
Worldlines and Worldsheets:
Pioneered by Einstein and extended by string theorists, the concept of worldlines is examined in detail here.
The String Theory Series:
The History of String Theory:
The story of the development of one of the most remarkable theories in modern physics.
Introduction to String Theory:
An introductory overview of this exciting new field of physics.
Gravity and String Theory:
How string theory solves the major problem of modern physics: integrating quantum mechanics and general relativity.
How string theory incorporates the last of the mathematically possible symmetries in the universe.
The Dimensions of String Theory:
String theory's famous higher-dimensional formulation that may explain some of the most elusive properties of particles and the universe as a whole.
Dimensions, Wound Strings, Branes, and Calabi-Yau Spaces:
The shape of strings and their ability to encircle dimensions, giving rise to unique new properties.
The Many Types of String Theory:
The many different formulations of string theory and how they all merge into one under a complex web of dualities.
New Developments in String Theory:
New theoretical studies and discoveries involving string theory.
