Just finished rereading Project Hail Mary again and itās really interesting that Stratt is not a scientist. Sheās an administrator, a politician, a leader. Not a scientist. Sheās surrounded by some of the smartest people in the world, and theyāre speaking in very science-y terms, and she has no idea what is going on. So what does she do? She turns to Grace and asks him to explain it to her. And he does, he explains the very complicated stuff in a way she, a non-scientist, can understand, because heās a teacher. Thatās what he does. It works very well from a narrative perspective because you, the reader, also donāt know what all this stuff means, so Grace explaining it to Stratt also explains it to you. But I also think maybe this is part of the reason Grace became so important to Project Hail Mary, why Stratt dragged him around everywhere- and she really does take him everywhere with her- not in spite of the fact that heās a junior high school teacher, but because of it.Ā
