[ARC5] Environment - unexplained effects.

  Hmmm.  Well, about 40 years ago (the topic is now environment, not
  ARC-5) I was a farmer.
  Local wisdom precluded doing certain things when an east wind was
  blowing.
  Part way thru studying maths and physics, I regarded this advice with,
  (how shall I say this) - some caution, perhaps even quiet amusement.

  One summer I was mowing (hay) and the shuttle mower was just cranky.
  The overload kept tripping, and I had to 'back-up' constantly to
  re-engage the mechanism.
  I didn't get much hay mowed.

  That was before lunch.  After lunch, exactly one hour later, using the
  same mower, in the same paddock etc, the mower ran sweetly.
  I noticed the wind had swung 180 degrees - from east to west.  
  Sometimes environment DOES affect "things".
  That's all I can say ... except I certainly don't understand how the
  wind could affect the mower.
