About

Echoes of Science is a YouTube channel (@echoesof.science) and an online encyclopedia of true, surprising moments in history, and the science that explains them.

How we make the films

Every story starts with research: primary sources, scientific papers and reputable histories, each linked on the story's page. Where historians disagree or the evidence is thin, we say so in the film.

The films mix real archive material with our own animation. Photographs, footage, maps and documents come from public-domain and openly licensed collections around the world (NASA, Wikimedia Commons, Europeana, national archives and museums), and every item is credited in the film and its description. Maps, diagrams and animation are drawn in code (Python) and 3D scenes are rendered in Blender. Music is by Kevin MacLeod (incompetech.com, CC BY 4.0). The narration uses an open-source text-to-speech voice (Kokoro). Reconstructions and illustrations are labelled as such; we never present AI-generated images as real photographs.
