If I had more time, I would read original treatises in mathematics. The reason is because — when I do get a chance to go over such writings — it is so much clearer to me that math isn’t just a bunch of static pronouncements that everyone agrees about, but a conversation built on emergent […]

I have a new historical figure that I want to invite to my imaginary dinner party with fascinating but dead people I wish I could talk to. And that’s this guy, Karl Pearson. A British Germanophile who lived from 1857-1936, Karl was a quirky, free-thinking mathematical giant in the field of statistics. He had a
Today I post on maths, and games, and a puzzle. In 1883 the brilliant mathematician Édouard Lucas brought a logic game to Western audiences in 1883 he called “the Tower of Hanoi.” Cottoning onto the Orientalism that made Asia and Asia Minor seem exotic and fascinating to Westerners, he marketed it as a kids’ puzzle.

Tycho Brahe (d. 1601), arguably one of the best naked-eye astronomers in history, also had one of the most famous noses in history. Mostly remembered for his accurate and detailed observations on the locations of stars and planets, twenty-year-old Tycho got into a drunken argument with a distant cousin about who was the better mathematician.
I love that as I get ready to write up my syllabi for this coming fall semester, perhaps a wee bit wistful of my fabulous summer coming to an end, I am reading about a time in the early 20th century when teaching college students was a lot more stressful. And that’s where the great

This is Hertha Ayerton, a British Engineer whose discoveries unveiled mysteries about the behavior of electricity and helped develop technology to protect soldiers in the trenches of the First World War from poisonous gasses. Sarah Phoebe Banks was born in 1854 to a family of eight children, her father dying when she was just eight.
Scholars think that the diameters of these various circles on the wall of this church of San Nicola, in Pisa, Italy, were an intentional representation of the famed Fibonacci sequence made in the 13th century. (They represent the first nine numbers: 1, 2, 3, 5, 8, 13, 21, 34, and 55.) Leonardo Fibonacci was from

This is maybe the first computer bug, and relates to one of the more famous anecdotes adorning the legendary reputation of Grace Hopper, one of the most important developers of the computer in the 20th century. Hopper (d. 1992 age 85) earned her Ph.D. in mathematics from Yale and was working as a professor until

I think maps are really interesting, and often I think the older ones are the best. This is a picture of the very oldest known map of the world, and it comes from the ancient Babylonian civilization (700-500 BCE). Maps are by nature symbolic representations, and so looking at how the cartographer imagined the space
This is a 16th century translation of “The Emerald Tablet”, among the most famous texts on alchemy ever. Although it purports to be from Egypt (that’s where a lot of medieval alchemists thought their sources originated), the first text we know of comes from an Arabic 6th/7th century source. Isaac Newton, himself an occultist, translated

This is Plympton 322, and this mathematical tablet written in cuneiform has been studied a lot to work out how much the Babylonians understood trigonometry. I love how much we still can learn and study about the history of math!
Fibonacci was an early 13th-century Italian who made Europeans aware that the Arabic number system we use today is much better for doing math than the Roman Numeral system medieval people had been using. Plus he wrote out the Fibonacci numbers, which are shown here in his most important book, _Liber Abaci_ (Book of Calculations).

M.C. Escher, “Angels and Demons,” part of a series called “Capturing Infinity,” 1960. Escher worked on consultations with several mathematicians to develop much of his artwork.
I would have liked to have met this man, who was as eccentric as this visage here implies. This is none other than Paul Erdös, a Hungarian mathematician who published more papers than any other to date (over 1,500) and worked with so many other scholars (he co-authored with over 500) that math geeks know
