Word of the Day:

"To study the behavior of elusive animals, scientists routinely tag them with GPS location trackers. But such devices' battery capacity limits how long they operate. ... So biologist Rasmus Worsøe Havmøller of the University of Copenhagen and his colleagues turned to another abundant power source: kinetic energy generated by an animal's movements. Their kinetic tracker, which Havmøller's team recently tested on domestic dogs, a wild pony and a European bison, could theoretically survive for the entire life span of an active animal." — Rachel Crowell, Scientific American, 9 Sept. 2023

Ever watch a top spin? Or see one pool ball collide with another and send it across the felt? When you do, you’re witnessing kinetic energy—the energy of something in motion. Kinetics is a branch of science that deals with the effects of forces upon the motions of material bodies, and something described as kinetic has to do with the motion of material bodies and the forces associated with them. Both words were adopted in the 19th century from the Greek word kinētikos (meaning "of motion") for use in the field of physics, but the adjective kinetic proved too apt for broader application, and by the 1930s it was being used to describe people and things full of literal and figurative energy as well.
