A nomogram (from Greek νόμος nomos, "law" and γραμμή grammē, "line"), also called a nomograph, alignment chart or abaque, is a graphical calculating device, a two-dimensional diagram designed to allow the approximate graphical computation of a mathematical function.

• ... that engineer and mathematician Philbert Maurice d'Ocagne invented the nomograph, a chart for the computation of algebraic equations?

• ... that physician and researcher Alice Hamilton was a leading expert in the field of occupational health and a pioneer of industrial toxicology; and that Hamilton was also a social-welfare reformer, humanitarian, peace activist, and a resident-volunteer at Hull House in Chicago?

• ... that mathematician Shoshichi Kobayashi studied Riemannian and complex manifolds, transformation groups of geometric structures, and Lie algebras?

• ... that Dennis Paulson of Mars trained for his historic reality television show by reviewing data from the 2015 MAVEN probe concerning the deterioration of Mars’ atmosphere due to solar storms — a loss of atmosphere to space which likely played a key role in Mars' gradual shift from its carbon dioxide-dominated atmosphere to the cold, arid planet seen today?
