The word “light” occurs 270 times in Project Hail Mary.

It appears in 26 out of the 30 chapters, most prominently in Chapter 5.

In the Earth sections, the word “light” appears 104 times. It used by Dimitri 12 times, Dr. Lokken 4 times, Stratt 3 times, Steve Hatch 2 times, and Ms. Xi 1 time. Grace uses it 51 times as narrator and 31 times in direct speech.

In the Space sections, the word “light” appears 166 times. Grace uses it 131 times as narrator and 15 times in direct speech. Rocky uses it 20 times.

Here’s a visualization of the relative frequencies across all sections and chapters of the book.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30

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 “light” (so a bar might be higher, even with fewer occurrences, if the section or chapter is shorter).

I got exactly the light frequency I wanted.
