A Brazilian mathematician confronts unequal publishing networks

Polynomial values could be generated through repeated addition, allowing gears to carry out a systematic mathematical method.

The machine transferred parts of calculation from human computers to mechanisms but still depended on designers, machinists and operators.

Accurate tables supported navigation, surveying, taxation and astronomy, activities closely tied to British administrative and maritime power.

The Brazilian mathematician known as Souzinha became the first Brazilian awarded a doctorate in mathematics.

His work sought solutions and general methods in areas then central to European mathematical research.

His career linked scientific ambition, education and nation-building in a former Portuguese colony.

Her translation of Menabrea's account appeared with notes much longer than the original and explained the unrealized machine's operations.

The table specifies operations, variables and repetitions in a form recognizable as an algorithm.

She argued that the Engine could follow operations supplied to it but could not originate ideas on its own.

Lovelace compared punched-card control with the Jacquard loom, linking patterns in textiles with patterns in symbolic computation.
