Virtual Experiments are multi-dimensional nonlinear movies of real experiments available on the web in any modern browser.
Virtual Experiments are not simulations. The user has full control of various parameters in the experiments so that he/she can carry out the experiment in their browser* just as if they were remotely controlling the real experiment. No physics or other science is coded into a VE, and whatever may be discovered in the real experiment can also be discovered in the VE.
Virtual Experiments are not intended to replace the real hands-on laboratory, but they can offer value as warm-ups to the real thing, or when equipment is scarce, dangerous, or expensive. They can be repeated as often as you like, and can't be broken.
Virtual Experiments are developed at the University of Reading (UK) Department of Physics for student levels from GCSE through to final-year university using a well equipped photographic studio and staff who contribute to their design, production, and programming.
