Hi folks! Nearly two decades ago I wrote the interactive structure factor tutorial, to help people understand diffraction beyond the simple explanation of Bragg's law. As such it has been one of the longest lived interactive teaching tools on the web.
However time and technology have caught up with it, and it is increasingly difficult to run, requiring plugins, security exceptions, and even obsolete browsers. So new I've completely rewritten it using modern web technologies. Try it here: http://www.ysbl.york.ac.uk/~cowtan/sfapplet2/sfintro.html It should work on any version of Firefox or Chrome since about the mid Permian, and I expect Safari and Opera as well. It's even useable on tablets (although a big screen helps). Internet Explorer will probably work since version 9. Show me a userbase and willingness to help with testing and I might be able to get it running on IE 7 or 8. Problem reports very welcome. Once it's stable this version will replace the existing version. Kevin -- EMAIL DISCLAIMER: http://www.york.ac.uk/docs/disclaimer/email.htm
