Made in 1923, this short film is one of the earliest attempts to put Albert Einstein's physics on screen for a general audience, using animated diagrams and title cards rather than the archival photography or expert interviews later documentaries would rely on. It walks through the two pillars of his work: special relativity, which Einstein published in 1905, and general relativity, which he spent roughly the following decade, from 1907 to 1915, developing into its final form. The film's animations try to render ideas that resist plain illustration, like the bending of light around mass and the relationship between space, time, and gravity, using the visual vocabulary available to filmmakers in the early 1920s, just years after Einstein's theories had upended physics and made headlines worldwide. As a historical artifact it says as much about how science was popularized in the silent-film era as it does about relativity itself, a snapshot of physics education before television, before CGI, and before relativity had fully settled into scientific orthodoxy.
