Simulations
I have developed an extensive range of computer simulations which demonstrate various concepts in Physics. These simulations are written as Java Applets so can be accessed on any computer using a web browser. For example, a Michelson Interferometer applet shows the pattern that would be seen at the exit plane of an interferometer. The user has control over mirror position and the position of the imaging camera. I use these demonstrations regularly in my teaching (first and second year) to give students a more visual picture of the concepts involved. I also promote the simulations as a way to prepare for undergraduate laboratories. A link to the main page is given here.
An applet highly used by our students is one that I have written to perform linear regression of experimental data. The results of an experiment can be pasted into the main page and the program calculates the line of best fit and displays a graph of the results. Visit this applet here.
I make these simulations available to the general Physics community via the internet. Recent downloads have included educators in USA, UK, Canada, Romania, Germany and Australia.
I have begun to investigate using newer technology such as smart phones and tablets as a platform for simulations of physics principles in a teaching environment. I have produced and distributed an uncertainty calculator for use on mobile devices (Android and iPhone). I am also using the HTML5/Javascript platform to create new simulations (which will run on computers, tablets and phones).
