The 3-plate technique for generating a flat surface. Archimedes' Principle. The photoelectric effect. Gunpowder and nitroglycerin and nitrocellulose (guncotton) syntheses. Agriculture. Plumbing and the concept of sewage handling. DNA. The transistor. ENIAC.
All infinitely more useful than the stoichiometric formulae for anything, which tell you nothing at all about how to actually make it (since there's no structure information).
The aerodynamics section is woefully misleading; generating lift was never the problem, it was getting a sufficient power-to-weight ratio. The Wrights' chief achievment was in obtaining a new, lightweight engine.
