Physics definition

    I find the following definition of physics
    The science of matter and energy and of interactions between the two
    Is the definition redundant in special relativity?

    I would define physics more as, human fabricated concepts used to explain our sense perception with experiment. So i would say its the interaction between the functioning of the mind and ideas formulated to explain the phenomena we perceive as being real.

    Seems like a dreary definition to me. These so-called "human fabricated concpets" are mere descriptions to real phenomena which is observed in nature. As with all things in nature we give them names so as to create a universal language of terminology so that we're all on the same page.

    but what about the redundance in the wikipedia definition of physics?

    I would say no, because light has no rest mass, for example, so there is an effective difference between mass and energy.

    It depends :smile:
