Zindel himself was a high school chemistry teacher, so it is no great stretch to equate the character of Tillie, with her love of science, to Zindel. He admitted that he based the character of Beatrice, although with exaggeration, on his mother.
The most pervading image of the play is that of the mutations that derive from exposure to radiation. Tillie’s science experiment is the literal representation of this theme. The extension of this image is how exposure to difficult issues in life has mutated Beatrice and how, in turn, her actions have mutated Tillie and Ruth.
