The Ballmer Peak is a humorous concept from xkcd creator Randall Munroe suggesting programmers achieve peak productivity at a specific blood alcohol level (0.1337% BAC). Named as a play on Steve Ballmer and the Balmer series, the concept has no scientific basis but has inspired events like Originate's Ballmer Peak-A-Thon and satirical academic studies, including a 2024 SIGBOVIK paper that found no evidence of a productivity peak.
