   Any rotating system is real, for any sensible meaning of "real".   
      
   If the man and plumb bob are rotating with the merry-go-round, the man   
   must hold on and the plumb bob hangs inclined.   
      
   If the man and the plumb bob are not rotating, the man need not hold on,   
   and the plumb bob hangs vertically.   
      
   In no case does it matter what coordinates or reference is used, what   
   matters is whether the objects themselves are rotating.   
      
   This OUGHT to be obvious.
