Yes, one example of a paradox involving mathematical sets is Russell's paradox. It was discovered by philosopher and logician Bertrand Russell in 1901 and states that the set of all sets that do not contain themselves cannot contain itself. This is because if it does contain itself, then it would be a set that does not contain itself, which contradicts the original assumption. If it doesn't contain itself, then it would be a set that does contain itself, which also contradicts the original assumption. This paradox highlights the difficulties in defining sets and set theory.
