That’s what Atlantic tech blogger Alexis Madrigal calls Google’s Books Ngram Viewer. Google has scanned about 10 percent of all the books ever published. Enter any word or phrase into the search box, and the viewer returns a graph of its frequency of appearance in books published over the last two centuries. Note that the searches are case sensitive, and you can compare the relative frequencies of up to
four five different words or phrases, separating them by commas in the search box. Say, “Nova Scotia” and “Ontario,” for example:
Try it yourself, and please send me any interesting pairings you come up with.
Madrigal’s blog is always interesting, but today’s entries are exceptionally good. In addition to the Ngram Viewer, there’s a post on the history or weird homemade windmills that sprung up in Nebraska’s Platte River Valley during the last two decades of the 19th century, another on names for the movie projector that were tried and discarded before 1900, and an entry on the cautionary implications of the Stuxet virus for our industrial infrastructure, most especially the electrical grid. (Stuxnet is the worm that targeted a particular type of Siemens control system used to operate centrifuges critical to Iran’s nuclear program. The virus kept itself hidden until they day it instructed the centrifuges to spin so fast they purportedly self-destructed.)
