We show that learning a convex body in $RR^d$, given random samples from the body, requires $2^{Omega(sqrt{d/eps})}$ samples. By learning a convex body we mean finding a set having at most $eps$ relative symmetric difference with the input body. To prove the lower bound we construct a hard to learn family of convex bodies. Our construction of this family is very simple and based on error correcting codes.
