  It is shown how to obtain conformal blocks from embedding space with the help
of the operator product expansion. The minimal conformal block originates from
scalar exchange in a four-point correlation functions of four scalars. All
remaining conformal blocks are simple derivatives of the minimal conformal
block. With the help of the orthogonality properties of the conformal blocks,
the analytic conformal bootstrap can be implemented directly in embedding
space, leading to a Jacobi-like definition of conformal field theories.
