Hofstadter as an 8-year-old was fascinated by exponents and subscripts; upon seeing his physicist father's papers with notation like 'X sub 1, X sub 2', he hypothesized that subscripting might be an operation on numbers analogous to superscripting's exponentiation, but was disappointed when his father explained subscripts were merely a naming convention for variables.

“when I was a kid, I was 8 years old as I recall when I found out about uh exponents...I saw a paper uh that my dad was reading...there were uh there there little things that said X sub 1, X sub 2...My dad told me, 'Oh, that doesn't do anything. It's just the way of naming variables.' And I was so so disappointed. [21:01]”
