Sources and selection
Physical explanations connect observations to models that can be tested. Here you can explore physics, astronomy, chemistry and space exploration, from introductory demonstrations to technical talks. The topic links help separate a first explanation of a concept from a closer look at an experiment, instrument or mission.
Indie Picks is organized from video metadata and uploader descriptions; it is not a full-video editorial review. HN Library retains community discussions. Sources and data notes
