True, but you've taken it out of context. That was part 1 of a series 
in Sound On Sound that already runs to 58 parts. The first part or 
chapter of any significant work tends to be a bit lighthearted in order 
to get readers comfortable with the subject matter.

Now, tell me truly whether you fully understood the maths outlining the 
Bessel Functions in parts 12 and 13, or how S&H leads to A/D and D/A 
converters in parts 16 and 17, or the theory of Pulse Width Modulation 
in part 46, or... Well, you get my drift. If you want hard facts, 
they're all there, too. And if you would like to discuss Quantum 
Mechanics or Cosmology, we can do that as well.
