Some of the Earliest Maps of Stonehenge, Made by a Druid-Obsessed English Vicar
These maps and illustrations appeared in British antiquarian and vicar William Stukeley’s 1740 book, Stonehenge, A Temple Restor’d to the British Druids. Harvard’s Widener Library has recently digitized its copy of the book. You can see the whole text here.
In more than 30 illustrations, Stukeley’s book documents the way Stonehenge appeared when he visited it in the early 18thcentury. The historian was only the second scholarly investigator (after the 17th-century antiquarian John Aubrey) to take an interest in the site, and the first to publish a comprehensive account of what he found on his visits, including images of the way that the monument looked in context of the surrounding farmland.

Artificial Muscles from Fishing Line and Sewing Thread. ”The high cost of powerful, large-stroke, high-stress artificial muscles has combined with performance limitations such as low cycle life, hysteresis, and low efficiency to restrict applications. We demonstrated that inexpensive high-strength polymer fibers used for fishing line and sewing thread can be easily transformed by twist insertion to provide fast, scalable, nonhysteretic, long-life tensile and torsional muscles. Extreme twisting produces coiled muscles that can contract by 49%, lift loads over 100 times heavier than can human muscle of the same length and weight, and generate 5.3 kilowatts of mechanical work per kilogram of muscle weight, similar to that produced by a jet engine.” Via.
