I would like to ask if there are any aspects of algebraic number theory related to physics (for example in string theory or Moonshine etc).

I am thinking of attending a course on algebraic number theory but in order to decide I would like to know how useful it might end up being for me.

  • $\begingroup$ Number theory is well known to be related to physics via moonshine. I want to know about aspects of algebraic number theory though. $\endgroup$ – Marion Feb 7 '15 at 11:27
