  The status of the uncertainty relations varies between the different
interpretations of quantum mechanics. The aim of the current paper is to
explore their meanings within a certain neo-Everettian many worlds
interpretation. We will also look at questions that have been linked with the
uncertainty relations since Heisenberg's uncertainty principle: those of joint
and repeated measurement of non-commuting (or otherwise `incompatible')
observables. This will have implications beyond the uncertainty relations, as
we will see the fundamentally different way in which statistical statements are
interpreted in the neo-Everett theory that we use.
