Some things really bring out the scientist in OneMonkey. Questions of paper weights (or, if we’re being picky, the mass of a square metre sheet) allowed him a happy half-hour with Vernier calipers, a conversion table, and a stack of comics and books. How thick does paper have to be before it looks and feels like a book cover? How thin before it starts to seem inconsequential (by which I mean amateur, not see-through)? The three of us sat rubbing pages between our fingertips, hmm-ing and considering, ranking our preferences (if we had the cover like this comic and the pages like that book…?). Entertaining, useful, and it makes us feel like we’re progressing. Hopefully fast enough.
