To work through the questions that form the heart of Schrödinger's Cormorant, you are going to need a little bit of mathematical know-how, but not too much. When I wrote the content, I had in mind someone who is, perhaps, in their last year of high school and has studied maths to that sort of level. But I really hope it will be more widely useful than that. If there are a few bits of maths and physics you need to brush up on, this can easily be done through other web resources. There are links to a few suggestions included below (they are only suggestions - in no way connected to Schrödinger's Cormorant - and there are plenty of all alternatives that are quite easy to find).
Things worth knowing a bit about before you get stuck in:
Basic algebra. Nothing fancy but there'll be lots of constructing equations to express physical relationships, rearranging and simplifying equations, and substituting one expression into another etc.
Basic calculus: Differentiation, including 1st and 2nd derivatives, chain rule and product rule; Integration, including definite and indefinite integrals, integration by parts and by substitution.
Trigonometry: We'll make a lot of use of Pythagoras' theorem and of sine and cosine functions. In addition, we'll occasionally use some trigonometric identities, such as double angle formulae.
The guiding principle of Schrödinger's Cormorant is that the maths should be accessible, so that you can work through all - or at least most - of the derivations and examples yourself.
