On 7/18 Stephen Birkett wrote on the subject of
hammer momentum physics:
"Looking at this hammer/string interaction for even a short while
indicates to me that no amount of elementary physics will
reveal very much about the process of energy transfer.
I believe arguments based on momentum, energy,
square pulses, fourier analysis etc. are all doomed to fail...sorry to
say it again...primarily because of inherent non-linearity, but also
because there are too many inter-related parameters."
Where a mathematical reasoning can be had, it is as great a folly
to make use of any other, as it is to grope for a thing in the dark
when you have a candle standing by you.
