Long ago, I made the conscious decision to make resources on this site free. For now and forever. I strongly believe that teachers have a hard job, and I just want to make it a little easier and hopefully contribute (in some small way) to the retention of physics teachers.
I have spent thousands of hours working on this site and we have now had almost one million downloads. If I’d charged just £1 per download then I’d have, well, a million pounds…
I’m not asking for a million pounds but if you have found me work useful then a donation on buymeacoffee would be greatly appreciated:
