Dear God, please take note

As an engineer I spend much of my day writing observations and change requests because there is something wrong with the product I am involved in engineering/validating. Therefore I feel compelled to comment on something that pissed me off today about physics.

Although physics in the majority of applications is a decidedly clever beast it does have one rather annoying feature which would be good to have removed:

When I stick my finger in my pint glass to remove a spec of unidentified something that is floating in my precious beer, I always manage to successful corner the offending spec against the side of the glass. BUT every time just as I go in for the kill and try to press it up against the side of the glass so I can pull it out, the little bastard slips around my finger into an ocean of un-patrolled beer. Damn fluid dynamics!
