I'm doing a PhD (particle physics) at a British university, and I'm at the point where I'm starting to think about career options. Staying in physics as a postdoc is a potential option but I've heard all about how a career in academia as a physicist is a competitive world to succeed in. However, I'm not against leaving the UK for a good job, but right now I'm limited by only knowing how to speak English. I'm considering learning another language but don't know which one tp pick. Which one would be my best bet - either to go somewhere as a physicist or as someone doing a job that physics graduates typically end up doing? Additional info: I'm not too concerned about which languages are harder to learn than others, but ideally if I leave the UK it would be for some warm & beautiful place rather than somewhere similar to the UK. Thanks.
