The Open University's OpenLearn website is a free and open educational resources for learners and educators around the world. In the LearningSpace, where Open University learning materials are freely available, you may study in your own time, away from any formal teaching environment. Visit the LabSpace to share and reuse educational resources. Download some learning materials, adapt to your needs: translate, shorten, extend, add examples... and then of course, place it back for others to benefit!

This applet demonstrates an artificial chemistry. Each circle is an atom, that floats around and can become bonded to others to form a molecule. The reason for using a strange abstraction of chemistry like this is that you can do some really cool things in a simple system. The applet above takes you through some of the possibilities. Perhaps the coolest thing you can do is template replication - the process DNA uses to make copies of itself. If you choose the right rules in the applet above you can actually get this working - follow through the challenges to find out how.

PhysicalGeography.net is an educational web portal that focuses on a specific area knowledge known as Physical Geography. Physical Geography is a sub-discipline of two much larger fields of study - Geography and Earth Sciences. The main purpose of Physical Geography is to explain the spatial characteristics of the various natural phenomena that exist in Earth's hydrosphere, biosphere, atmosphere, and lithosphere.

The goals of the Physics2000 Educational Initiative are to make physics more accessible to students and people of all ages by developing an innovative Internet Website, aimed at all ages, emphasizing imagery, interactivity and hierarchical organization, and by developing live classroom courses for undergraduate non-science majors with unconventional topical organization and web support; to demonstrate the connection between modern technology and earlier basic research by working backwards from familiar current devices and technologies to general principles established much earlier by basic experiment and theory; to foster an appreciation of the accomplishments of 20th century physics, as we approach the year 2000 by focusing public attention on current research achievements in physics and explaining their significance and by developing new inderdisciplinary and cross-topical undergraduate courses for both majors and non-majors.

Fun, interactive simulations of physical phenomena that make bridges to the real world, from the Physics Education Technology project at the University of Colorado. The simulations can be run directly from this site (click here), or downloaded to your computer for off-line use (click here).

Online texts and study materials covering classical physics, computer science, quantum physics, relativity, pedagogy, statistics and data analysis, and modern physics. Hosted by UPSCALE: Undergraduate Physics Student Computing and Learning Environment, Department of Physics, University of Toronto.

National Oceanographic Partnership Program (NOPP). Partnering ocean science. education, and technology. Educators: Use data from ocean drifting buoys to integrate ocean science into your classroom science and math instruction. Enhance your lessons with suggested educational activities and curriculum materials developed and tested by teachers, or you can use only the data, background information and reference images. Scientists: Utilize near real-time data on flow, sea surface temperature, wind and ocean color to augment your current research or future investigation plans.

In 1993 an international group of six scientists, including IBM Fellow Charles H. Bennett, confirmed the intuitions of the majority of science fiction writers by showing that perfect teleportation is indeed possible in principle, but only if the original is destroyed. Teleportation promises to be quite useful as an information processing primitive, facilitating long range quantum communication (perhaps unltimately leading to a "quantum internet"), and making it much easier to build a working quantum computer.

At the start of the twentieth century, scientists believed that they understood the most fundamental principles of nature. Atoms were solid building blocks of nature; people trusted Newtonian laws of motion; most of the problems of physics seemed to be solved. However, starting with Einstein's theory of relativity which replaced Newtonian mechanics, scientists gradually realized that their knowledge was far from complete. Of particular interest was the growing field of quantum mechanics, which completely altered the fundamental precepts of physics.

What does Quantum Universe mean?
To discover what the universe is made of and how it works is the challenge of particle physics. Quantum Universe presents the quest to explain the universe in terms of quantum physics, which governs the behavior of the microscopic, subatomic world. It describes a revolution in particle physics and a quantum leap in our understanding of the mystery and beauty of the universe.
