Hi, stupidly i left university after graduating and entered the world of work, after 2 years am now looking to return, does any one have any advice on how best to go about this? Am looking to do a Phd in theoretical physics/applied maths but as of yest haven't got a firm topic in mind, so any advice on how to narrow the options down would be helpful to!

If there are any similar threads please let me know,

Thanks

Chris
