Andrei Tarkovsky's 1972 film Solaris, in which a psychologist is sent to a space station orbiting a planet with an alien intelligence and meets his dead wife there. It is the full movie, uploaded by Mosfilm.

Developmental and synthetic biologist Michael Levin speaks at a Harvard Extension student event on bioelectricity, body intelligence and regenerative medicine. He discusses how cell electrical networks guide growth and form.

A 1984 Computer Chronicles segment in which Susan Kare explains the ergonomics and interface design of the original Macintosh. She introduces the interface step by step for newcomers.

Jacob Geller's video essay on empty cities and what they say about our relationship to places, using games, literature and aerial imagery. It touches on works such as Invisible Cities.

Louis Rossmann explains why NYC commercial landlords keep storefronts vacant rather than lowering rents. He points to commercial mortgage-backed security loan terms and inflated property valuations.

Kurzgesagt explains why exercise alone does little for weight loss, since the body compensates by adjusting its total energy expenditure. It argues exercise is still very valuable for health.

Rebecca Watson's video critiquing physicist Sabine Hossenfelder's earlier video on gender care for transgender minors, arguing it mishandled the evidence.

A NOVA documentary with neuroscientist Heather Berlin exploring the subconscious and what drives our decisions. It uses sleepwalking, anesthesia, improvised rap in an MRI and game theory to probe how much of the brain's work is hidden.

Jean-Marc Jancovici gives an MIT Media Lab talk on whether technology can save us from climate change. He argues from a physical view of energy that economic growth, energy use and climate impact are tightly linked.

Not Just Bikes argues that self-driving cars will worsen sprawl and car dependence and harm cities. The video compares car-centered and people-centered urban design and weighs what cities should do instead.

Not Just Bikes argues that urban noise comes mostly from motor vehicles, drawing on the book Curbing Traffic and a visit to Delft, a city that takes noise seriously.

DIY Perks builds a realistic artificial sun for dark winters, using a powerful water-cooled LED, a satellite dish reflector for near-parallel rays, and a scattering layer to mimic the blue sky.
