"One of Greg's poems is like a super bouillion cube. I read it and it brews up a whole gallon of me."

"Greg Keith's poetry makes accurate statements about physics, and at the same time elevates scientific concepts to a level that is intensely personal, emotionally and aesthetically charged, and (in the best sense of the word) spiritual."
