Human computers were used to compile 18th and 19th century Western European mathematical tables, for example those for trigonometry and logarithms.Although these tables were most often known by the names of the principal mathematician involved in the project, such tables were often in fact the work of an army of unknown and unsung computers.

[29] [30] In 1976, Steve Jobs and Steve Wozniak sold the Apple I computer circuit board, which was fully prepared and contained about 30 chips ...
A chart with descriptions of each Myers–Briggs personality type and the four dichotomies central to the theory. The Myers–Briggs Type Indicator (MBTI) is a self-report questionnaire that makes pseudoscientific claims [6] to categorize individuals into 16 distinct "psychological types" or "personality types".
The term type has not been used consistently in psychology and has become the source of some confusion. Furthermore, because personality test scores usually fall on a bell curve rather than in distinct categories, [6] personality type theories have received considerable criticism among psychometric researchers.
