Greetings: Coffee is an important engineering
subject, so I tought you might like knowing about
this tidbit I read in Scientific Amercan about how
to aviod siplling your coffee while wlaking from
the break room to your cubicle or to a meeting.
The writer, Rod Roduin, notes that the secret
can be found by observing waiters in restaurants.
They manage to carry multiple drinks, filled nearly
to the top of the cups and/or glasses, without spilling
a drop while walking quickly around the dining area.
Their secret: Long stride, short stride.
Long stride, short stride.
Break up any rhythm that could set up a
resonance in the vessles, and the sloshing is prevented.
I'll have to remember that.

holding a tray full of full glasses is much easier.
the resonant frequency for the whole system is much
much lower (many times greater moment of inertia).
also they are holding it from below and use the
elbow joint as suspension to absorb variations in
height. that's my observation as a physicist
anyway
