I would like to introduce the spinor-helicity formalism for massless particles, which drastically simplifies the calculation of their scattering amplitudes. I will then discuss some of the physical significance of the appearance of poles in amplitudes. A combination of these ideas will lead us to the conclusion that a theory with interacting massless spin-1 particles must be based on a Lie algebra.
