Dendrochronology (or tree-ring dating) is the scientific method of dating tree rings (also called growth rings) to the exact year they were formed in a tree. As well as dating them, this can give data for dendroclimatology , the study of climate and atmospheric conditions during different periods in history from the wood of old trees.
In 1921, the last time the eye of a major storm like Hurricane Milton struck Tampa Bay, the city was only home to a few hundred thousand Floridians. Now, it’s one of the fastest-growing cities ...
Time-lapse photography of biological phenomena was pioneered by Jean Comandon in collaboration with Pathé Frères from 1909, [6] [7] by F. Percy Smith in 1910 and Roman Vishniac from 1915 to 1918. Time-lapse photography was further pioneered in the 1920s via a series of feature films called Bergfilme ( mountain films ) by Arnold Fanck ...
