Physicist...because i hated physics and it was mean to me so they must be uber clever to like it firstly and then be good at it!
I voted mathematician, but who can really tell? Intellect doesn't have much effect on someone's interests. Someone could have made a great mathematician, but his/her heart lied with Biology, or even Literature or something for that matter.
There's no option to vote for myself
I say physicist since they learn Physics and have to occasionally link their knowledge to all three sciences and frequently Maths also.
