FAQs
How to use the site
How do I modify the spreadsheets on this site to meet my needs?
All the Excel workbooks are write protected to make it harder to corrupt them accidentally, but they are not secured with passwords. You are therefore free to modify them in any way that you wish. We do not have the resources to support further development of the workbooks and so any enhancements you make to them are "at your own risk". Please observe the conditions of the project's CC licence.
Is the site compatible across all browser platforms?
We would dearly like to say, "Yes, it is". Unfortunately, in the world of HTML coding not everything is that simple. The formulae on the site are marked up using MathML, the standard language for doing so. Unfortunately, Internet Explorer (from Microsoft) has chosen to not play ball entirely fairly with industry standards of coding. As a result, there are some fundamental, problems with the rendering of the site on IE (all versions).
Instead, we recommend (in order):
I've spotted a mistake! How do I get it corrected?
At the top of each article, just underneath the heading, the name of the principal author of that section appears. If you click on that name, you will be able to send a personal email to him/her directly from the website.
If you want to debate the rectitude or implementation of the methods described, you may post a comment on any page - although you will have to be logged in with a validated email address.
Is it possible to see a more carefully rendered image?
Yes! Simply click on the image and it will open in a temporary screen.
Clicking on the outward-arrows button at the bottom right of the image opens an even crisper version.
Press <esc> to close the image.
Is it possible to see a more carefully rendered version of the formulae?
Yes! Click on any formula to see a more detailed rendering.
Depending on your browser or browser settings, you may need to
- right-click on a formula
- Select "Format" --> "MathML"
- Select "Settings" --> "Zoom trigger" --> "Click"
- Select "Settings" --> "Zoom factor" --> "200%"
- Select "Settings" --> "Math Renderer--> "MathML"
This should need to be done only once.
