He recalls: "We all felt very macho walking around campus wearing these [slide rules] like guns in holsters. Plus, we knew how to use the things, and this made a big impression on the girls." Hah! Maybe at Utah. Levin explains that the slide rule became the calculator of choice in the 1630s, when it was invented by English Episcopal minister William Oughtred (15741660).

Ever-cheaper plastic 3D printers and downloadable gun blueprints have created a new route to homemade guns and have led to legal battles to stop their proliferation. Plastic guns have been shown to shatter after firing a few shots, but a 3D-printed metal gun could be more robust. In 2013, the start-up Solid Concepts used a type of powder bed fusion to make the first 3D-printed metal shotgun to showcase the technology’s capability. For now, however, it’s much easier and less costly to assemble an untraceable metal gun out of readily available parts than to 3D print one, according to Philip Cook, a gun policy expert at Duke University. Metal 3D-printing companies say they will continue to focus on space exploration and military endeavors.
