The QCD Song*
By James Hartle
On the lattice we will be
'Till we solve it, QCD
Dimensions come and dimensions go
But there's one thing that we know
Beyond four we're not meant to see
So it's in four that we'll always be
Hail to thee, oh, QCD
To thee we pledge our loyalty!
*written on the occasion of the 60th birthday celebration of Bob and Joan Sugar. Hartle shares the same birthday with the Sugars but is a year younger. He has recently taken to saying that he is much younger than they are. Unfortunately, Hartle does not have access to the sophisticated MILC data analysis codes. If he did, he would undoubtedly realize that the age difference, a 50% effect in 1940, is now less than a 2% effect. We wish them all well and hope that in the future the effect will be reduced below 1%.
