horizon

PBS Space Time explains what happens as you approach and cross a black hole's event horizon, using Penrose diagrams and light cones as the tool for understanding spacetime there.

The 1993 BBC Horizon documentary on Richard Feynman, using interviews with colleagues and Feynman's own storytelling. It covers his life and work through to his final illness.

Stanford physicist Leonard Susskind gives the first of two mini-lectures on "ER = EPR", the idea that quantum entanglement and wormholes are related. It covers what lies behind black hole horizons.

A two-minute BBC Horizon clip demonstrating the McGurk effect, where what you see of a speaker's mouth changes the sound you hear.

A short clip shows the horizontal stabilizer jackscrew of a Boeing 737NG cycling through its motion. It illustrates how pitch trim is physically adjusted.

Adam Neely's Ableton Loop 2017 talk links rhythm, pitch and synaesthesia. He shows that polyrhythms sped up become chords, so tempo and pitch are related by ratios.

A PBS Space Time episode explaining how space and time swap roles inside a black hole's event horizon. It is part of the channel's black hole series.

A PBS Space Time episode asking what black holes really are and whether events can happen inside them. It covers event horizons, time dilation and common misconceptions about black holes.

Part one of a four-part upload of a BBC Horizon documentary featuring Richard Feynman, in which he talks about physics and looking at the world from another point of view.

PBS Space Time episode on the black hole information paradox, covering how black holes seem to destroy information, the no-hair conjecture and the proposed role of the event horizon. It is part of a series on black holes.

ScienceClic visualizes what you would see falling into a black hole, from the approach and the accretion disc to crossing the horizon, in 15 minutes.

Veritasium explains what a black hole should look like, using J.P. Luminet's 1979 work and a cardboard 3D model to show how light bends around it. It was made just as the first black hole image was released.

Alan Kay's 2015 talk on the power of simplicity, arguing that systems become simpler by building on more sophisticated fundamental building blocks and that big research horizons drove invention at Xerox PARC. It ranges across computing, tools and scaling software.

A Boeing 737 pilot explains the runaway stabilizer checklist, the procedure for stopping unwanted horizontal stabilizer movement such as an MCAS activation on the 737 MAX. He walks through the steps, the trim cutout switches and the jackscrew mechanism, and shows a simulator run including the manual trim wheel effort.

A short unofficial NASA-style spot from Reid Gower's Sagan Series, setting Carl Sagan's words about humanity spreading through the Solar System to visuals and music.

People Make Games explores VRChat, the social virtual world that many consider the metaverse people actually like, interviewing users and covering its communities and uncertain future.

A BBC Horizon clip demonstrating the McGurk effect, where the same audio sounds like different syllables depending on the mouth movements you see. It shows that people integrate visual speech information into what they hear.

Part one of Capt. Grace Hopper's 1982 NSA lecture on the future of data, hardware, software and people. It includes her humor, her nanosecond demonstration and views on scaling and resisting old ways of doing things.

Planets is a track from the audiovisual album Oscilloscope Music, in which the audio signal drives an analog oscilloscope directly. The left channel sets horizontal deflection and the right sets vertical, so the sound draws vector graphics.
