About the site

This web site was produced as an entry to the Royal Society of Chemistry's 'Exemplarchem' competition, 2002.
The main content is adapted from an undergraduate library project.


Although any non-original graphics or media have been used without expressed permission, all copyrights and ownerships are acknowledged.
Any original content is hereby noted to be devoid of copyright and may be freely used.


If you are experiencing problems or glitches viewing the pages in this site, the following information may help.


The site is nominally designed to work in Internet Explorer or Netscape Navigator 4.0 or later. However Netscape users are strongly encouraged to use Netscape 6.2, and for Internet Explorer, version 6.0 or later is recommended. Other suitable browsers are Opera 6.0 or Mozilla 1.0 (upon which Netscape 6.2 is built) - don't forget to download the Java-enabled versions!
The site has been tested on Microsoft Windows XP and Windows Me, with Internet Explorer 6.0 and 5.5, Netscape 6.2, Opera 6.03, Mozilla 1.0 and Netscape Navigator 4.08. Netscape Navigator 4 corrupts the layout on some pages, all other browsers format the content correctly.


To fully appreciate the site, you'll need to have the Macromedia Flash plugin (version 6) for your browser - chances are, you probably have it already, but if not, you can find it here. If you're using Internet Explorer, you will be given the opportunity to automatically the Flash plugin if it does not exist. The Welcome page will also attempt to detect and warn you about your Flash plugin, if necessary.
There are also Java applets and VRML objects in the site. You will need a plugin to view the VRML world. One example is Parallel Graphics' Cortona VRML client - get it here. Again, auto-installation occurs with Internet Explorer.
The only browsers that seems to work reliably with the Java applet are Internet Explorer and Netscape Navigator 4 - the Sun Java 2 Runtime Environment (v1.3.1) used by Netscape 6, Mozilla and Opera fails to load the applet in testing on Windows, at least.
It's also useful to have a JavaScript-enabled browser (most are, make sure you haven't turned it off).


Whilst most non-alphanumeric symbols are supported by the ASCII character set, at least one used within the site is not, for this, you will require the 'Symbol' font to be installed on your system. The rest of the site is designed with the 'Verdana' and 'Tahoma' fonts. All of these are present on Microsoft Windows computers.
Netscape Navigator 4 does not fully support the extended ASCII set, and so some characters will appear as question marks when viewed using this browser. Again, viewers are recommended to use Netscape 6.2 or Internet Explorer instead.

Schrödinger's Cat

Here's our cat superbly illustrating the paradox of two-state wavefunction mixing portrayed by Schrödinger's infamous cat thought-experiment:

Schroedinger's Cat
Fratton as Schrödinger's kitty - is she alive or is she dead?

(Training is underway for illustration of the two-catflap diffraction effect)
