The history of mathematics, as of any science, is to some extent the story of the continual replacement of one set of misconceptions by another. This is of course no cause for despair, for the newly instated assumptions very often possess the merit of being closer approximations to truth than those that they replace.
— Frank C. DeSua, American mathematician (born 26 Oct 1921). quote icon
Thumbnail of Alfred Tarski
It may be unpopular and out-of-date to say—but I do not think that a scientific result which gives us a better understanding of the world and makes it more harmonious in our eyes should be held in lower esteem than, say, an invention which reduces the cost of paving roads, or improves household plumbing.
— Alfred Tarski, Polish-American mathematician and logician (died 26 Oct 1983). quote icon

Thumbnail of  Giovanni Maria Lancisi,

A decade after that, he identified malaria as being transmitted by flies, and not due to “bad air.”
In what century was he born? (i.e. in which century was the carrier of malaria understood?)

On 26 Oct 1948, a killing smog blanketed the small town of Donora, Pennsylvania, in the U.S.. The people of that working class community went to bed not knowing that a suffocating cloud of industrial gases would descend upon them during the night. The cloud, a poisonous mix of sulfur dioxide, carbon monoxide and metal dust, came from the smokestacks of the local smelter where most of the town worked. Over the next five days, twenty residents died and half the town's population were hospitalized.
What metal was produced by the smelting plant outside Donora?
