A Timelapse Video Constructed From Online Photographs

The University of Washington and Google have teamed up to create incredibly impressive timelapse videos of popular tourist locations using pictures pulled from the Internet. 

The team first collected a whopping 86 million photos and organized them by location and vantage point. They were then sorted in order of date; next, the viewpoints were warped to match, and the colors were altered to create consistency and reduce flicker. The result is several videos of different places growing, changing, or diminishing—some have a simple "seasonal rhythm," like the timelapse shots of Lombard Street in San Francisco, while others show geological changes, like at a hot spring in Yellowstone National Park. They even compiled videos of major building renovations, like at the Basilica St. Maria of Salute in Venice and Neuschwanstein Castle in Germany. The team explained their process in a paper and will soon release the code they used to create it.

Tracing a word’s origin and evolution can yield fascinating historical insights—and the weird nicknames used in some states to describe their residents are no exception. In the Mental Floss video above, host John Green explains the probable etymologies of 29 monikers that describe inhabitants of certain states across the country.

Some of these nicknames, like “Hoosiers” and “Arkies” (which denote residents of Indiana and Arkansas, respectively) may have slightly offensive connotations, while others—including "Buckeyes," "Jayhawks," "Butternuts," and "Tar Heels"—evoke the military histories of Ohio, Kansas, Tennessee, and North Carolina. And a few, like “Muskrats” and “Sourdoughs,” are even inspired by early foods eaten in Delaware and Alaska. ("Goober-grabber" sounds goofier, but it at least refers to peanuts, which are a common crop in Georgia, as well as North Carolina and Arkansas.)

Learn more fascinating facts about states' nicknames for their residents by watching the video above.
