General notes on use of Mathematica Demonstrations
The Wolfram Demonstrations Project is a collection of interactive simulations in many areas including physics. Weblinks to demonstrations, which provide supplementary material, appear throughout this course. Bear in mind that some of the demonstrations are beyond the scope of this course, purely included for interest and as an insight into the work you may come across in later years. None are directly examinable.
To use these demonstrations a copy of the (free) Mathematica 6 Player is needed. This is already installed on all computers in public access labs... (If you have your own machine, you might want to install the free player yourself - but be warned that this is a large file and with a slow internet connection it will take a very long time!)
The weblinks for the Mathematica Demonstrations (the first one is down below....) will take you to the specific demonstration. Choose the ’Download Live Version’ option. Here you will find the option to download Mathematica Player if you need to, else just select the download of the file at the bottom of the page.
Depending on the computer you are using, it will either recognise this download as a Mathematica file and open the Player application, or you might need to save the file to disk and open the downloaded file in the Mathematica Player manually. (You will find the software in Start / Departmental Software / Science and Engineering / Physics).
Watch out for security settings on good ol’ Internet Explorer complaining about pop-up windows (just allow pop-ups from this site) and you should be on your way.....
Some simulations will offer you some guidance on how to use them to get the most out of them. This one is pretty self-explanatory.....
