I have this guide "Math on Call: A Mathematics Handbook (Paperback) by Andrew Kaplan". When DS8 forgets a formula, he runs to grab his Edward Zaccaro/MM (quickly flips to the page he knows) or this guide.

Edit to add: I realised the Usborne Physics and Chemistry Guides are on my "wish list". smile
