  1. All problems fromPhysics III to VI can be solved 'by heart' by memorizing six simple numbers (correct to a few percent): c = 3·108 m/s α= 1/137 ≡ e2/(4πε0ħc) m = 511 keV ≈ ½ MeV/c2 mN = 1836 m ≈ 1 GeV/c2 k = 25 meV/300K + for transition to SI-system: e = 1.6·10−19 C → 1eV = 1.6·10−19 J ε0 = 107/4πc2 C/Vm μ0 = 1/ε0c2 = 4π·10−7 T/(A/m) (T = Tesla) NA = 6·1023 molecules/mole and: ħc = hc/2π ≈ 200 eV·nm (← AP) = 200 MeV·fm (← NP) = 0.2 GeV·fm (← PP) Natural constants
