The page explores the Dzhanibekov effect, also known as the tennis racket theorem or intermediate axis theorem, which describes a surprising phenomenon observed in rotating bodies. It highlights the involvement of cosmonaut Vladimir Dzhanibekov during a critical 1985 mission to salvage the Soviet space station Salyut 7 after a complete shutdown. This event was so significant that it inspired a Russian film released in 2017. The phenomenon is notable for its unexpected and counterintuitive behavior when objects rotate around certain axes.
