Science documentaries make you follow an argument, not just admire a result, taking you from the quantum scale to the edge of the cosmos and everywhere in between. This collection gathers 792 free science documentaries.
Explore physics and quantum mechanics, chemistry, evolution, genetics and DNA, neuroscience and the brain, climate and earth science, mathematics and engineering. You will find films that trace the great discoveries, profile the scientists behind them, and explain the frontiers of what we know, from broadcast science strands and independent communicators who go deeper than television allows.
Whether you want a clear explanation of a hard idea or a tour of the biggest questions in modern research, this is the collection that shows the working rather than presenting conclusions as spectacle.
