Some eagle-eyed readers of Artemis have spotted a few errors; printing, plot or maths, and have been quick to point them out.
1. The Safe[]
When Jazz tries to open Jin Chu's hotel room safe she sees that his code includes the numbers 0, 1 and 7. As the code must be 4 digits she concludes there must be 54 different combinations.
Some fans have argued that it should actually be 36 different combinations.[1]
2. Marine[]
In the first printing Andy Weir referred to Bob Lewis as an ex-marine rather than an ex-Marine. A marine (lower case m) referring to sea life whilst Marine (upper case m) refers to the military.[2]
3. Fiber Optics[]
1st hardback edition of Artemis pg 189 - Jazz says that fiber optic lines can only be 15km (9.3 miles) long without the use of repeaters but we currently have fiber optic cables in use that are 80-100km[3] (49-62 miles) long without repeaters. A single strand of fiber might only be manufactured at 15km, but they can be fusion spliced together to make longer runs.
