Throwback to the research trail - Château de Chillon on Lake Geneva

From 1755 a swirling map of claims showing locations of native lands, British Claims east of the Mississippi, French to the west. Note the Cherokee lands throughout what would be western North Carolina, Tennessee, etc., clusters of native towns across the region. Shows the vast "Six Nations" confederation of the Iroquois stretching from Illinois to upstate New York. #map #maps #nativeamerican #Cherokee #history #USA

My new book, Language and the Rise of the Algorithm, was featured on the Page 99 Test, a blog based on the premise that opening a book to page 99 can give a good idea of its contents. Page 99 of my book discusses an #18thCentury debate about whether #algebra should be considered a #language—a debate that gained a newfound relevance in the computer era.

The mathematician Nikolai Ivanovich Lobachevsky was born #OTD in 1792. He developed a non-Euclidean geometry that shows up in areas ranging from relativity to the designs of M.C. Escher.

In Lobachevsky's geometry there exists more than one line parallel to a given line and passing through a point not on that line. Although the term "Lobachevsky geometry" is still used, we more frequently refer to it as "hyperbolic geometry" – a term introduced by Felix Klein.

All roads lead to Rome. Meet the earliest known European map with a scale: This woodcut "south up" map by Erhard Etzlaub offers a route to Rome - located on the top of the map - through early modern German speaking Europe. The map was printed as a single-sheet item, and was made in Nuremberg for the Holy Year 1500.

Etzlaub wanted his "Rom-Weg" map to be bought, so he offered colored versions too, like the one you see, because these were more expensive.

Inspired by the vibe here, I just posted my first new blog post in a long time: "Medieval Manuscript Fragments in the Classroom". Read here: https://tinyurl.com/yc6bkf7n

The post discusses fragments as survivors of systematic book destruction, shares my experiencing of teaching with them, and details a new frame design #UBC is implementing. Happy to discuss teaching with these hidden gems!
