A video showing a virtual camera built in Blender that simulates lenses and film layers using path tracing, to make physically modeled photographs.

A satirical animated dialogue in which a naive developer insists MongoDB is web scale while a database expert mocks him. It parodies the NoSQL versus relational debate.

Dr. John McDougall argues at TEDxFremont that starch-based diets are what humans were born to eat, drawing on 40 years of nutrition and disease work.

Sebastian Lague explores an ant-inspired algorithm and simulates ant and slime mold behavior, using compute shaders. Source code for both simulations is available.

Wendover Productions explains counterintuitive riot control techniques based on research, showing that effective tactics tend to avoid violence.

A scene from Moneyball in which Brad Pitt's character argues with scouts who pick players on intangible impressions instead of performance data. It is a four-minute clip.

CGP Grey's six-minute explainer of the relationships the UK could have with the EU, based on Barnier's slide, shown as orbits of different closeness. It explains why the UK's red lines ruled out the closer options.

Dr. Terry Wahls tells how she used diet to manage her multiple sclerosis and get out of a wheelchair, drawing on mitochondrial biology. TED flagged the talk as health advice based on personal narrative.

The first video in Not Just Bikes' Strong Towns series explains the financial instability of North American cities, based on Strong Towns research. It argues that low-density suburban growth costs more to maintain than it brings in.

Veritasium argues that electric energy is carried by fields around the wires rather than by electrons moving through them, using a thought experiment with a large circuit.

CGP Grey compares airplane boarding methods, based on an arXiv paper, and shows why the intuitive back-to-front approach is slow while random or outside-in boarding does better.

An animated visualization of basic quantum mechanics using a free particle, with simulations based on the actual equations. It covers waves, particles, and how measurement collapses the wavefunction.
