Be careful, while learning from Feynman, that not all
formulas are in SI units. The formula 11.11, for example
(page 11.2 vol II) gives a ridicule result for the ionization
energy of hydrogen) if the m, e and h-bar are in SI units.
To get the correct result use old CGSE units: m=9.1*10^-28,
e=4.8*10^-10 and H-bar=1.06*10^-27. The same is true
for the formula for omega-zero (natural frequency of oscillating
electrons. I was surprised by this because the formula 11-1
(on the previous page contains epsilon-zero, which would
not appear in the CGS).
