摘要：

We rewrite the 1+1 Dirac equation in light cone coordinates in two significant forms, and solve them exactly using the classical calculus of finite differences, The complex form yields ''Feynman's checkerboard'' - a weighted sum over lattice paths. The rational, real form can also be interpreted in terms of bit-strings.
