The words "happy" and "sad" occur 57 times in Project Hail Mary.

The word happy appears 40 times in total: 8 times in Earth sections and 32 times in Space sections.

The word sad appears 17 times in total, entirely in Space sections.

By speaker, Rocky dominates both words. He says happy 23 times and sad 12 times. Grace says happy only 3 times (1 time on Earth, 2 times in Space) and sad once. The narrator uses happy 9 times (2 times on Earth, seven in Space) and sad 4 times (all in Space). On Earth, happy is used by Dimitri (2 times), Dr. Lamai, Dr. Lokken, Grace, and Steve Hatch (once each).

Here’s a visualization of the relative frequencies of each word across all sections and chapters of the book. The charts show “happy” and “sad” respectively.

Each coloured bar represents a section and is colour-coded for Earth sections (green) and Space sections (purple).

The grey bars represent the chapters, which are marked with ticks and numbers.

The y-axis is the relative frequency, i.e. the proportion of tokens in that section (or chapter) that match (so a bar might be higher, even with fewer occurrences, if the section or chapter is shorter).

This is happy!
