An intense electron beam, when combined with the LHC (LHeC) or, in the further future, the FCC hadron beams (FCC-he), can lead to a unique, energy frontier DIS collider at CERN. Recent measurements at the LHC and the Tevatron have lead to a very precise determination of m_top with, however, sizeable theoretical and phenomenological uncertainties inherent to hadron-hadron scattering. High precision top physics can be performed in ep scattering at the LHeC which is analysed in this presentation. Besides, it is also discussed how polarised ep scattering (at low and very high energies) can lead to very interesting prospects for measuring the scale dependence of the weak mixing angle at very small scales O(1)GeV and much beyond the Z pole where LEP/SLC provided two measurements of $\sin^2\theta(M_Z)$.
