Yup, lack of advanced science concepts and an accumulation of errors despite a pretension to working problems for the audience.
Even some basic geography errors - early in the book, he claims that the sample had to be landed in Saskatchewan for a high latitude to match the Baikonur Cosmodrome in Kazakhstan. Baikonur is at 45 N latitude, about the same as the border between North and South Dakota. Everywhere in Saskatchewan is North of the 49th parallel and south of 60. Sigh.
Yoon Ha Lee really plays with fun math concepts. Great stuff. The Ninefox trilogy was a real entry point for me to begin to appreciate Korean mythology.
