pattern recognition

Huygens Optics explains the Fourier transform and shows how a lens performs one optically. A DLP projector is used as a Fourier filter to do simple pattern recognition on lithographic character patterns.

Veritasium examines which experts have real expertise, drawing on chess research and work by Klein and Kahneman. It explains that expertise comes from pattern recognition built through deliberate practice in valid, feedback-rich environments.

Veritasium explains how Penrose tilings and quasicrystals overturned the belief that 5-fold symmetry and non-periodic crystals were impossible, including an interview with Paul Steinhardt.

Huygens Optics experiments with etching tiny patterns in glass, covering hydrofluoric acid risks, buffered oxide etch, photoresist and chromium masks, and laser-induced etching. It ends with attempts at microscopic Tesla valves.

Grandmaster David Howell tests Magnus Carlsen by showing him chess positions and asking which famous games they come from. Carlsen recognizes many almost instantly.

An episode of Patriot Act with Hasan Minhaj exposing how tax-prep companies like TurboTax make filing confusing and costly even though many Americans can file for free. It combines comedy with reporting on lobbying and dark patterns.

Tom Scott visits the USPS Remote Encoding Center in Salt Lake City, where keyers decipher mail images machines cannot read. It shows the lengths taken to decode bad handwriting.

A Veritasium video on the logistic map, showing how a simple population equation leads to chaos and bifurcation. It connects the idea to convection, neuron firing and the Mandelbrot set, with interactive animations.

Casey Muratori shows how typical 'clean code' object-oriented patterns can cost large factors in performance. He benchmarks them against simpler data-oriented code.

CGP Grey explains that postal codes are routing instructions for mail rather than geographic regions. He looks at the quirks and problems this causes.

Michael Levin presents his lab's work on how cellular collectives use bioelectric networks to make anatomical decisions. Topics include pattern memories, regeneration and synthetic living organisms.

Cory Doctorow's DEF CON 31 talk describes how platforms decay in a pattern he calls enshittification. He lays out a plan to stop it through antitrust, interoperability and fixing the law.

Luca Sas's ACCU 2021 talk on Modern C, a style of C and C-like C++ aligned with data-oriented design. It covers centralized memory management, zero-is-initialization, error handling and API design.

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.

Greg Wilson surveys what empirical research actually shows about software development, why we believe it, and how to share that knowledge more widely. It covers evidence on practices such as TDD and design patterns.

Linguist Geoff Lindsey explores vocal fry: what it is, who uses it, how it relates to glottal stops and accents, and why some people dislike it.

Jon Gjengset spends about three hours livecoding complex changes in a Rust codebase with agentic AI tools, testing his hypothesis that AI is weak at non-pattern work. He documents where Claude Code helps and where it struggles.

Matt Parker of Stand-up Maths examines scatter plots that were claimed to show fraudulent vote-switching in Michigan's 2020 election. He recreates the analysis and shows that the pattern arises from comparing percentages across different bases, not from fraud.

Not Just Bikes contrasts traditional and suburban development in North America. It looks at the financials behind each pattern and argues that suburban development leaves cities unable to pay for their own infrastructure.
