Do I need a mathematical background to study astrophysics? [closed] Ask Question

Speaking from my experience of doing an astrophysics degree in the UK, I would say that you don't need to do a transition year beforehand.

University lecturers are aware that students will be coming from a variety of backgrounds and structure the course to accommodate that. In particular, there will be at least one or two mathematics courses in the first year designed to get everyone on the same page mathematically. For example, in the first semester of my degree I had a module called "Algebra and Calculus" which covered things like set theory, matrices, differentiation, integration etc. Then we had "Further Algebra and Calculus" in the second semester and "Mathematical Physics" (this was about modelling heat transfer, waves on a string etc) in the second year.

Furthermore, if you've already been accepted by a university, then they clearly think you are mathematically prepared enough. If you're still not sure, get in touch with a lecturer or two there and ask about suitable preparation materials; for example, a textbook or old problem sheets you could work on over the summer. If you're in the UK, take a look at the A Level Maths syllabus. This will give you an idea of the typical maths knowledge a first year physics undergrad will be starting with.

Also note that unless you go into very theoretical parts of astrophysics, you won't need that much complex mathematics, and certainly hardly any pure maths, so I wouldn't recommend studying too much of that beforehand, it's not necessary. If you can differentiate, integrate and know what a Fourier transform is, you're basically set.

One caveat: don't go into an astrophysics degree expecting every lecture to have an astro angle. The first half of my degree was almost purely maths and "classical*" physics-- you need that solid foundation before moving on to the specialised topics. Having said that, it makes it all the more worth it when you get there.
