Abstract
The three-dimensional space of plane parabolas y=ax^2+bx+c admits a natural conformal structure: Two points are null separated if the corresponding parabolas are tangent. I shall demonstrate how Riemannian conformal structures in seven dimensions with G_2 structure group arise onmoduli spaces of rational curves with self-intersection number six, or on solution spaces of certain 7th order ODEs.
