I'm planning on doing my 4000-word extended essay for International Baccalaureate on virtual particles (theoretical and particle physics really interest me). I'm starting to get quite stressed, though, as summer is half over, and we were advised to have, at the least, our research done by September, and I barely have a thesis! I was wondering what sort of topics would be good with particle physics. I was thinking of maybe doing a study on results from a Casimir effect experiment, but I don't want to get bored with this topic. Is there anything interesting that would be easy to write 4000 words on that I could do? Thank you for helping!!!!
