Experimental physics Definition and 145 Threads

Experimental physics is the category of disciplines and sub-disciplines in the field of physics that are concerned with the observation of physical phenomena and experiments. Methods vary from discipline to discipline, from simple experiments and observations, such as the Cavendish experiment, to more complicated ones, such as the Large Hadron Collider.

    Physics Documenting in Physics: Theory vs Experiment

    Is documentation and meticulous lab book keeping as big a part of theoretical physics as it is in experimental physics? From what I've seen, it seems like in experimental physics a big part is organizing files, noting where small changes have occurred, etc. Is it the same in theory? Does it vary...
