New in the collection: NC State aeronautics paperweight

If you know the story on this 2-inch by 3-inch cast iron paperweight (?), you’re one up on me — and on the experts at North Carolina State. “The university archivist,” I’m told, “thinks this likely dates from the 1930s or the 1940s and suggested that perhaps it was a student project rather than an item that was mass produced.”

Regardless, its simple depiction of Bernoulli’s Principle dates it no earlier than 1738.
