Hello, I'd really appreciate some opinions on this- I'll get a chance to do an extended essay for the IB program and I'm choosing physics, obviously. I'm not quite sure what to work on. I can choose to research something relating to experimental physics (where I design an experiment to find a relation between different physical quantities) or relating to theoretical physics (where I create a model for something, or maybe give an analytical discussion of a topic). It can't be something too broad, since the essay has a word limit of 4000. I get about 6 months to do this project, so once I start I'll have a long time to learn stuff if I need to. I'd rather do something more theoretical than experimental. Any thoughts on what could be good? I'm thinking classical field theory could be interesting to look into, but I have no idea what I could do related to that subject.
