      I don’t have a good memory, so I only remember the really simple ones by heart. Usually I try to understand the meaning of the equation instead, because then I can often figure out what the precise form is or look it up if necessary.

      I’m the same as Arttu!

      I remembered more equations during my A-levels than I do now! but i think the difference now is that i know how to derive them from first principles (well, the easy classical ones anyway, not the quantum ones) so I don’t need to memorise them.

      I use equations quite a lot, but I tend to use the same ones over and over and after a while they stick in your head.

      Not that many really. In day-to-day work most of the maths is already written up inside computer libraries for things like Lorentz transforms or anything else you would commonly use.
