Help please at theoretical physics question!

  1. Oct 24, 2011 #1
    Hello guys.
    I am a molecular biology student and at my physics class I have an assignment which says "What are the top 5 unsolved problems at theoretical physics nowadays? "
    I am thinking of including the;
    *string theory,
    *quantum chromodynamics,
    *quantum gravity,
    *theory of everything.
    Could you please help me, by telling me if i am at right way or suggest me to include other theories?
    Thanks in advance! :smile:

    Ps. Please forgive my poor English.
    1. The problem statement, all variables and given/known data

    2. Relevant equations

    3. The attempt at a solution

    I'm not a huge expert but let me clarify a couple things for you. Your points 1,2,4,5 are all really the same thing in the sense that you are talking about grand unification (well not #2 strictly, but its related). Unifying quantum mechanics and general relativity is probably the #1 thing on your list, and like I said 1,2,4,5 are all directly related to that, so I don't think you get use use them more than once :). Also, #3, quantum chromodynamics is a very well established field, not sure I would really call it an unsolved problem in physics. My 2cents.

    Edit: See this link for some helpful suggestions http://en.wikipedia.org/wiki/List_of_unsolved_problems_in_physics
