Balancing an Equation

     I grew up on a farm and spent my middle life in a small town and now live in a city.  A sort of immigrant.  A farm girl who became a professor.  A balancing act.
     Some years back, one of my math department colleagues posted on his office door a quote from George Bernard Shaw (1856-1950) :   

     The reasonable man adapts himself to the world: the unreasonable one persists 
     in trying to adapt the world to himself. Therefore all progress depends 
     on the unreasonable man.

At one time I much agreed with the Shaw quote.  Now (perhaps because I am older or because I now live near to Washington, DC and contentious party politics) I am more admiring of balance than unreasonableness.  Here is a lovely poem by Caroline Caddy about balance and numbers.
