Shortly before he died, Appel's father wrote him a letter while he was still at school.

The idea of Appel's hierarchical algorithm handling the many body problem is implemented in the direct boundary element method ( BEM) for computation of 3 D VLSI parasitic capacitance.

Though American mathematician Appel and Haben declared that they had proved Four color conjecture to be correct by using computers, which ran for 1200 hours, people still expect a simple theoretical proof instead of using computer.
