Among all fundamental particles, the top quark is the heaviest. Its mass
is a key parameter for making predictions at all energy scales. However,
the definition of the top quark mass is ambiguous. In addition, it is
not clear what is actually being measured by experiments. Does this mean
that experimentalists should give up their efforts to measure the top
quark mass more precisely at the LHC or is there hope to force a
breakthrough any time soon? I will give a flavour of recent measurements
and theoretical developments as well as mention a few ideas for what
could be the next steps to measure this much debated parameter more
precisely in the near future.
