[pct-l] Testing of Bear Cannisters / URSACK

[tom aterno]

That drive to understand the unknown and correct problems is what drives most engineers, particularly this engineer, and explorers, of which I classify thru hikers.  What is over that next ridge? Can I hike 33 miles in a day to reach the next resupply? Or, how can I prevent that machine from scrapping product again? I look forward to solving manufacturing problems every day. Now, if I could only solve my achilles tendonitis problem, my life would be better.

Do you REALLY want to be citing "Paghat the Ratgirl" as your authority on engineering?  :)

Actually, in my profession, what you are doing is "concrete thinking".  In fact, what I meant, and which was understood by the person to whom I was responding, is that engineering cannot describe everything, at all times.  There are things which evade understanding or description, and it therefore does not leave the totally accurate and complete description of everything, at all times, to engineering.

As this other website says:

"Conventional aerodymic analysis methods simply don't apply to insect wings.
Big deal! It doesn't mean bees can't fly, or that engineers say they can't fly. It just means that insect flight is very complicated and, even with computers, our fluid dynamic modeling techniques aren't yet able to quite handle such a complicated problem. Then there's the problem of verification. If you can't measure the pressures and velocities around a wing, how can you verify your calculations?"

"Ahem.  Wrong about the bee thing.  Its an old urban legend.  http://www.paghat.com/beeflight.html"
