How often do theoretical physicists do labs?

Well, the answer may vary a little from subfield to subfield: in high energy physics, the divide between theory and experiment is very stark, and theorists rarely come close to the actual doing of experimental work. read more

Likewise, do not mistake doing word problems for what a theoretical physicist does on a daily basis. Second, theorists can sometimes have to deal very closely with experimental work. Theories live or die by experiment, and if there are experiments that can test some of theories that you are interested in, chances are you will be interested in these experiments. read more

Theoretical physicists must have strong skills in math and a solid understanding of both basic and advanced concepts in physics. They often rely on computers to assist them with complex calculations, so they must have strong computer skills, as well. read more

Theoretical physicists (on the quantum side anyways) have abandoned the regime of reason. Things don't have to make sense. In fact many will claim, that reason no longer applies at that level. read more
