I find discussion about money rather distasteful and I apologise. I don't want to be thought of as a money-grubber (which is why I would not last two minutes in The City).
I remain committed to the site being freely available so that students can access it at any time both in and out of college. I will continue to maintain the site as long as it's relevant and useful.
Therefore I am going to suggest a voluntary donation system. I would ask colleges and schools who use the site regularly to make an annual donation. I know that this will impact on budgets that are tight as they are, but in effect it is the cost of two physics textbooks.
I have also felt it to be necessary to increase the price of my resources to £10. Even so I hope you would agree that it still represents very good value for money.
I have now set up a PayPal Account to make it easier. It is as secure as any internet transaction.
To donate by cheque:
Please e-mail me at
I will give you my address.
Please make cheques payable to James Irvine.
Please do NOT send cash for obvious reasons.
Please do NOT e-mail me your credit card number for security reasons. Besides, I would not know what to do with it.
