Computing is a work in progress, but all of the errors below are ours and ours alone.
p. 16 — “Sumerian Abacus” — The Hebrew word אבק (abaq) is appears backwards due to an oversight during production.
p. 131 — “Artificial Intelligence Coined” (graphic) — This math in the graphic is incorrect:
It should read:
(Thanks to Carl Hoffman)
p. 244 — “NP-Completeness” — The Cook-Levin Theorem refers specifically to the statement that SAT is NP-complete, not to the entire theory of NP completeness. Cook later stated that he was surprised that so many other problems were found to also be NP complete (the current list is in the hundreds). (Thanks to Scott Aaronson.)
p. 358 — “VPL Research, Inc.” — VPL created the first “motion capture suit,” not the first “motion picture capture suit.” (Thanks to Michael Cohen for reporting this.)
p. 508 — “Augmented Reality Goes Mainstream” — The phrase “and one out of every seven people use a cell phone” should read “one out of every seven people who use a cell phone.”
p. 514 — “The Limits of Computation?” — Although Yin, Juan, et al. “Bounding the Speed of ‘Spooky Action at a Distance.’” Physical Review Letters 110, no. 26 (2013) claim to measure the speed of information propagation due to quantum entanglement and find it to be at least 10,000 times faster than the speed of light, the idea of using entanglement to send information faster than light is not a matter of debate or interpretation among mainstream physicists.
