Neuroscientist Anil Seth argues in this TED talk that perception is a controlled hallucination: the brain constantly predicts the world and our shared agreement is what we call reality. He also touches on the construction of the self.

A roughly 14-minute interview with OpenBSD founder Theo de Raadt at ruBSD 2013. He talks about making painful changes, getting real feedback, mitigation techniques compared to other OSs, and virtualization.

A one-month review of the Xreal (formerly Nreal) Air AR glasses by The Tech Chap, covering unboxing, setup, what the display looks like, and how mixed reality differs from AR. It ends with the reviewer's overall thoughts. The video is sponsored.

PBS Space Time explains Noether's theorem: conservation laws such as energy and momentum are consequences of deeper symmetries. It also covers why those laws hold only under certain conditions.

David MacKay's TEDxWarwick talk uses basic arithmetic to show how much land and energy renewables would need to power a country like the UK. It explains the limits of sustainable options and why they should still be pursued.

A CAD-based animation from the Max Planck Institute for Plasma Physics showing how the Wendelstein 7-X stellarator is configured and what its fusion research aims to achieve. It runs about 11 minutes.

Mitchell Hashimoto walks through his setup for running a NixOS virtual machine on a Mac as his development environment, with a config repo on GitHub.

A parody video contrasting Nokia's polished N97 promotional material with the sluggish, buggy reality of using the phone.

Brian Peiris demonstrates RiftSketch, a web app where you write JavaScript with Three.js while wearing an Oculus Rift and watch the world around you change live. It runs on Firefox builds with WebVR.

Johnny Lee demonstrates head tracking with a Wii remote and a head-mounted pair of IR LEDs, so a screen acts like a window into a 3D scene as your head moves.

Linus Tech Tips reviews the Looking Glass 8K holographic display, a glasses-free 3D monitor. The video shows the display in action and explains how it works.

Tom Scott visits the Swiss Military Museum to see the last surviving 1970s tank-driving simulator. It uses a real camera moving over a miniature model landscape rather than any computer graphics.
