Despite my best efforts and those of several others, there are, inevitably, some errors in A Map of the Invisible/Atom Land. Apologies.
When they get spotted and reported, they get fixed in future editions. Where they might cause confusion to the reader who have older editions, I am collecting them on this page. I’ll also add any note or queries which come up and seem like they might be interesting, just as I did with Smashing Physics.
