This is a free site!

All of the educational materials and resources which I have written or produced on this site are provided free of charge for anyone in the world to make use of. I didn't make this site and the resources in it to make money, but rather because scientific education is important. If you want to have any of it for yourself, please help yourself to it by downloading it.

This is also a free site in a second sense: you are free to use and/or modify all of the material which I have written, except anywhere where another author is named (e.g. many photographs), under the CC BY-NC-SA 4.0 license. This kind of freedom is often termed copyleft. You are particularly welcome to use my materials for educational purposes

In detail, this means that you are free to share (copy, distribute and transmit), and to remix (adapt and change) the materials and resources, so long as you attribute me as the author (but not in any way that suggests that I endorse you or your use of them), you do not use them for commercial purposes, and if you alter, transform, or build upon them, you may distribute the resulting works only under the same or similar license to this one.

This in no way diminishes my right, which I assert, to be identified as the author of those materials and resources on this site which I have written, in accordance with the Copyright, Designs and Patents Act 1988.

If you have any specific questions regarding whether a particular resource is available under the CC license, or how to attribute a resource, please email me at ACN.Norman@radley.org.uk or contact me using my contact details and provide the URL of the resource in question.

Examples of crediting

Ask yourself whether an interested viewer/reader/listener/other user is able to easily see that I wrote the original, and the freedoms associated with that (license notice). If they can, great!
