Electromagnetic Polarizabilities of Pions and Nucleons

The response of hadrons to electromagnetic probes is highly constrained by chiral dynamics; 
but, in some cases, predictions have not compared well with experimental data. I give a 
biased review of the electromagnetic polarizabilities of pions and nucleons, including a 
slant on recent efforts to determine polarizabilities from first principles.
