ACKNOWLEDGMENTS
 
As is always the case, there are people to thank.
 
Russ, for his excruciatingly patient education in physics (the mistakes are mine, not his);
 
Barry, for his insights;
 
Steve, for the mind-set;
 
Ralph, for his analysis;
 
John, for the law;
 
Fred, for the access;
 
Gerry, for his friendship;
 
Quite a few others who entertained my endless questions and ideas—even the dumb ones;
 
And all the men of goodwill who hope, as I do, that the corner may finally be turned, and were willing to talk about it.
