Want to know more about the new science? These sites offer plain English (usually) explanations and discussions about subjects like high energy physics, complexity, and chaos theory.
New Scientist's Introduction: Quantum World - A great resource that explores in plain English many aspects of quantum physics and other new sciences.
Physics 2000 - An excellent interactive introduction to modern physics, developed by the University of Colorado at Boulder.
Stephen Hawking's Website - Devoted to the work of Stephen Hawking, one of the great minds of contemporary physics, this site includes some of his lectures to the general public.
Exploring Emergence - A fun site that uses interactive applets to explore examples of emergent behavior.
The Particle Adventure - An interactive tour of the inner workings of the atom, sponsored by the Particle Data Group.
Boids - This site features a java applet demonstrating the pioneering program of the same name (from 1986), which was one of the first models of emergent complex behavior.
Some Basic Ideas About Quantum Mechanics - As the title indicates, presents some basic ideas about quantum mechanics, in language a layreader can understand.
Quantum Mysteries - The latest on the mysteries of quantum physics, along with some intriguing possible explanations.
Spooky Action at a Distance - A user-friendly discussion of Bell's Theorem, which proved the quantum mechanical principle of nonlocality. According to this principle, just putting a particle in a measuring device at one location can instantly influence another particle at another, distant location.
Quantum Mechanics History - An interesting narrative covering the beginnings and development of quantum theory.
Wave-Particle Duality - An explanation provided as part of the HyperPhisics website maintained by Georgia State University.
The Uncertainty Principle - An explanation of one of the basic principles of quantum mechanics from Stanford University.
Chaos Home Page - A straightforward discussion of Chaos Theory, presented for students and others unfamiliar with the subject.
The Official String Theory Web Site - An easy to read resource on the cutting edge world of String Theory.
