A short MIT Math Lab video showing millimetric droplets bouncing and walking across a vibrating fluid bath, guided by their own pilot waves. These droplets show diffraction, tunneling and quantized orbits, which were once thought to belong only to quantum systems.

Veritasium explains in detail how LIGO detects gravitational waves, with a laser interferometer measuring displacements smaller than a proton. The video focuses on the extreme precision and the techniques needed rather than the general discovery story.

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.

Sabine Hossenfelder explains why she thinks faster-than-light travel may not be ruled out. She argues that the standard objections from special relativity are inconclusive.

A short demo of a walking droplet on a vibrating silicone oil bath passing through a double slit and producing interference, a macro-scale analogue of pilot-wave behavior.

A PBS Space Time episode introducing de Broglie-Bohm pilot wave theory, an interpretation of quantum mechanics that avoids much of the strangeness of the mainstream views. It is aimed at curious lay viewers.

Huygens Optics explores the idea that space is a non-linear elastic medium, and uses simulations to show how wave energy might be confined locally into particle-like objects. It touches on inertia, the Schwinger limit and the vacuum as a medium.

PBS Space Time surveys five realistic options for interstellar travel, from conventional rocket fuel to antimatter and nuclear pulse propulsion. The options rely only on known physics.

A Bell Labs film in which Dr. J.N. Shive uses a mechanical wave machine to demonstrate reflection, standing waves, resonance and impedance matching. He includes some equations but relies mostly on real-world examples a layperson can follow.

A short video from the trafficwaves.org site showing how traffic jams and standing waves form, including the fight between cheaters and blockers at an exit-lane backup. It also touches on how individual driving behavior affects the flow.

The Google I/O 2009 keynote introducing Google Wave, a real-time collaborative communication and document platform. It includes a long live demo and the developer preview announcement.

Technology Connections examines an old feature-rich microwave and shows how it uses a humidity or steam sensor and lookup data to cook food well, arguing it beats many modern ones.

Smarter Every Day uses high-speed and Schlieren photography to show how a whip crack is a supersonic shockwave formed at the tip. It references academic papers on whip physics.

Tech Ingredients demonstrates how microwaves work and how they affect objects at range, then shows ways to defend against them. It includes a correction about rectifier output frequency.

A CNN report in which Nima Elbagir witnesses migrants being auctioned as slaves at a property outside Tripoli, Libya.

Cleared Defense Department footage of Raytheon's Phaser high-power microwave weapon bringing down drones during a 2013 live-fire demonstration at Fort Sill. Raytheon says it has halved the payload size and is offering the system for operational use.

Looking Glass Universe explains de Broglie-Bohm pilot wave theory (Bohmian mechanics) as an alternative to the standard interpretation of quantum mechanics. The video lays out the pros and cons of the theory and links to related videos on contextuality and entanglement.

Physicist Jacob Barandes discusses his view that quantum mechanics can be formulated without wave functions, using a stochastic, probabilistic approach. The long interview covers measurement, the foundations of quantum theory and the history of the field.

Lex Fridman interviews Mark Zuckerberg in the metaverse, with both appearing as photorealistic avatars from separate locations. They discuss Meta's AI, VR and the future of avatars.

Guardian News coverage of Mark Zuckerberg's 2021 reveal of Facebook's metaverse plans alongside the rename to Meta. It shows a glimpse of the VR and AR vision.

The original Broadway cast performs 'The Internet Is For Porn' from the musical Avenue Q, with press-reel footage synced to the live performance.

Dave Plummer interviews Dave Cutler, architect of VMS and Windows NT, in a roughly three-hour conversation about his career and the history of Windows.

Dollar Shave Club's low-budget launch ad, in which the founder jokes his way through the case for cheap mail-order razors.

The official music video for Blues Traveler's song Hook, remastered in HD. The song is known for using the melody of Pachelbel's Canon while its lyrics comment on how hooks work.

Oskar Stalberg explains how Wave Function Collapse assembles island dioramas from handcrafted tilesets in Bad North. He covers the theory, implementation, tooling, and how he blends art and technology.

The first part of a long series documenting Dave Bull's Tokyo woodblock workshop as it produces a reproduction of Hokusai's The Great Wave. It follows the carving, proofing and printing of the reward print for Kickstarter backers.

A one-minute New Scientist clip showing a Japanese experiment in which drivers on a circular track produce a spontaneous traffic jam that travels backward. It illustrates phantom traffic jams without any obstacle.

Dr. John Campbell reviews a mouse study on accidental intravenous injection of an mRNA COVID-19 vaccine and its potential to cause myopericarditis. He walks through the methods and findings and discusses the aspiration technique.

A one-minute clip from Chappelle's Show in which Dave Chappelle riffs on Ja Rule and the 'what does Ja Rule say' bit. It is a short comedy sketch with no technical content.

Dave Thomas, a co-author of the Agile Manifesto, argues at GOTO Amsterdam 2015 that Agile as a branded industry has lost its meaning. He says agile is an adjective, not a noun, and urges developers to reclaim agility.

Dan Abramov live-codes hot reloading with time-travel debugging at React Europe 2015, debuting Redux and its devtools. The slides themselves are driven by application state.

Tom Scott investigates the claim that the microwave was invented to heat hamsters, and interviews James Lovelock about freezing and microwave-thawing hamsters in the 1950s. It traces early magnetron uses beyond radar.

A roughly three-hour Lex Fridman podcast conversation with Brendan Eich, creator of JavaScript and co-founder of Mozilla and Brave. It covers JavaScript's rushed creation at Netscape, the browser wars, Firefox and Mozilla, and Brave's privacy approach.

A long documentary-style video arguing that slavery in the US effectively continued through convict leasing and the prison system until around 1942. It covers the constitutional carveout and the history of neoslavery.

Martin Donald explains the Wave Function Collapse algorithm using Sudoku-like constraint solving and shows how he implemented it with Blender and Godot. It links demos and reference articles.

Edward Kmett's talk to the NY Haskell User Group on the lens library, building from fmap and function composition up to lenses, folds and traversals. It shows how these composable combinators access and modify parts of data structures.

Admiral William McRaven's 2014 University of Texas commencement address, built around lessons from Navy SEAL training. It famously opens with the case for making your bed every morning.
