We will discuss the problem of time reversal symmetry and tests of this symmetry in nuclei and atoms. An effective method to test time reversal invariance in the non-strange sector is to measure parity and time reversal violating (T-P-odd) electromagnetic moments, (such as the static electric dipole moment). Parity and time reversal violating components in the nuclear force may produce P-T-odd moments in nuclei which in turn induce such moments in atoms. We will discuss the possibility that in some reflection asymmetric, heavy nuclei (which are radioactive) these moments are enhanced by three orders of magnitude. This opens the possibility to improve very significantly the limits on time reversal invariance.
