An overview of some recent results from the Mainz Microtron MAMI is given.
The selection comprises the electric form factor of the neutron, the amplit
ude ratios (E2/M1)(I=3/2) and (C2/M1) of the Delta (1232) excitation, the G
erasimov-Drell-Hearn (GDH) sum rule and the measurement of helicity depende
nt pi (+) and pi (0) photo-production cross sections, the electric and magn
etic polarizabilities from real Compton scattering and the generalized pola
rizabilities from virtual Compton scattering VCS and finally a determinatio
n of the s- and p-wave threshold amplitudes for pi (0) photo production.
