Cheng Lou's react-europe 2016 talk lays out a mental framework for thinking about abstraction levels in JavaScript tooling, from Angular and Grunt to Webpack and React. It uses that framework to reason about the cost of abstractions and how to choose between competing solutions.

Mathologer uses continued fractions to show why the golden ratio is the most irrational number, comparing it with root 2, e and pi and pointing to where this shows up in nature.

An excerpt of a C-SPAN interview in which Thomas Sowell argues that preferential admission policies produce mismatch, dropouts and resentment.

A demo of the Cubli, a 15 cm cube that uses reaction wheels to jump up onto a corner, balance there and fall in a controlled way to move. The video shows these three abilities chained into locomotion.

Huygens Optics shows how DIY photon sieves shape a laser's wave front, explaining how they differ from zone plates and how aperture count affects the focal point, with time-resolved visualizations of the diffraction.

A Veritasium video that follows the principle of least action from Bernoulli and Newton to quantum mechanics, asking whether light takes all possible paths at once. It includes experiments showing quantum waves.

A very short clip of Carl Sagan saying that to make an apple pie from scratch you must first invent the universe. It illustrates how everything depends on a chain of prior things.

A short clip of the audience at Valve's 2017 announcement of Artifact, a Dota 2 card game, reacting with visible disappointment. The footage captures the awkward silence and the logo reveal.

A very short clip from Taken 3 of Liam Neeson's character jumping a fence, edited with extremely rapid cuts.

Sandi Metz takes an ugly section of conditional code and refactors it into a few simple objects, bridging object-oriented theory and practice. The talk includes her take on the Gilded Rose refactoring kata and the idea that duplication is cheaper than the wrong abstraction.

Andrew Huberman's long Huberman Lab episode is a masterclass on dopamine. It covers the neural circuits, peaks and baselines, dopamine depletion, and 14 tools for motivation, focus and avoiding addiction.

Veritasium explains quantum entanglement and spooky action at a distance, walking through Bell's inequality and the experiments that rule out hidden variables, in under ten minutes.

Simon Sinek's TEDx talk arguing that great leaders and companies inspire action by communicating why they do something before how or what. He uses Apple as his main example.

Simon Sinek's TED talk presents the 'golden circle' model: great leaders and companies inspire action by starting with why they do something, before how or what. He illustrates it with Apple, Martin Luther King, the Wright brothers and, as a counterexample, TiVo.

Elm creator Evan Czaplicki's talk on how a file grows and when to split code up. He argues for keeping code in one file until it hurts and warns against premature extraction.

A two-minute satirical short film in which a woman leaves her phone at home and notices how everyone around her is absorbed in their screens. It became a viral comment on phone distraction and social disconnection.

A BBC Four documentary following Alan Bond and Reaction Engines as they pursue the Skylon spaceplane and its SABRE engine. It covers the history from HOTOL and the heat-exchanger breakthrough.

Scott Jenson, a veteran UX designer formerly at Apple and Google, argues that the 'UX/UI' split pits programmers against designers and narrows ambition in open source. He makes the case that desktop UX has stagnated and that open source projects could lead experimentation beyond current interaction models.

Professor Mike Merrifield of Nottingham explains in a mostly uncut conversation why light travels slower in glass. He treats light as a wave and describes how the material's electrons produce secondary waves that combine to slow it.

A short CNET demo of Bose's electromagnetic active suspension, which gave a very smooth ride but never reached the market. It shows the system in action.

Coast Guard footage of a Cirrus SR-22 pilot who ran out of fuel over the Pacific and deployed the airframe parachute, then escaped into a life raft. It shows the Cirrus Airframe Parachute System working in a real emergency.

The first lecture of MIT's 6.001 (SICP) with Abelson and Sussman, giving an overview of the course and an introduction to Lisp. It argues that computer science is about managing complexity and abstraction, not computers.

Jonathan Blow's DevGAMM 2019 talk argues that software knowledge is being lost between generations and that growing layers of abstraction could lead to a decline in technological civilization.

Casey Muratori's University of Twente guest lecture is a case study in how straightforward code can cut thousands of lines and tens of seconds of runtime down to a few dozen lines running in under a second. It uses concrete examples to show why software is often an order of magnitude slower than it should be.

Veritasium explains magnetism as a consequence of special relativity. Length contraction of moving charges makes a current in a wire attract or repel a nearby moving charge.

Episode 4 of Mike Maloney's Hidden Secrets of Money, explaining how currency is created through a chain of IOUs among the Treasury, banks and the Federal Reserve. It covers bonds, Fed checks, debt, taxes and fractional reserve lending, from a gold-and-silver advocate's viewpoint.

Runar Bjarnason's Scala World talk argues that restraint and precision in components beat power and flexibility. Constraints on parts make them easier to compose into systems.

Numberphile's Ben Sparks shows why the golden ratio is the most irrational number, using seeds, continued fractions and rational approximations. He also explains why plants use it for spacing leaves and seeds.

Sandi Metz argues that hidden assumptions in code are missing concepts, and shows how to name and expose them so code is easier to understand and change. It covers null objects and messages in Ruby.

Paul Grignon's animated documentary presenting his view of how banks create money as debt and why that system requires continuous growth. It outlines the historical background of modern banking.
