Today at the University of Minnesota Industrial Hygiene lab
we return to the on-going saga of our grad student's valiant efforts to get data.
We open on the scene of her meeting with her research adviser,
meet with Pete - ok
missing peak in last experiment - just what we wanted
annoying peak at 0.7 still there - hmmm
check out experimental set up - looks ok
find wiggly thing that's not supposed to be wiggly - hmmm
find leak - good
annoying peak at 0.7 gone - great
set up power source - good
turn power source on
power source "on" light lights up - yea!
power source makes the right ticking noises - good
fiddle with voltage regulator - looks right
loud pop - huh?
flash of white light at ammeter scale - wow, pretty lights
no more voltage
no more joy
Pete & I looked at each other and sighed ...
I'm now experiencing the joys of trying to get someone at the U's electronics shop to come fix my power source.
Maybe I'll go mattress shopping today. If it was an hour earlier, I might have called Mr.Gopher and suggested doing lunch.
I have nothing else to do in the lab until the power source gets fixed ...
I might as well laugh - it doesn't make my nose run afterwards.
