FortNine argues that e-bikes have injury rates and speeds closer to motorcycles than to pedal bikes. It argues riders should treat them with similar safety gear and caution.

A professor from Illinois compares the cost of building, fueling and operating a nuclear plant against a natural gas plant, using visual charts. It shows how construction time and interest rates dominate, when the investment pays off and when costs cross over.

A Kurzgesagt explainer on why the human population exploded and why growth is slowing, drawing on Our World in Data. It argues that birth rates fall as countries develop, easing overpopulation fears.

A roughly two-hour demonstration by Dan Ingalls of Smalltalk running on the Computer History Museum's restored Xerox Alto. It shows the integrated environment and language designed at Xerox PARC as personal dynamic media.

A short Stanford video in which Chao-Lin Kuo surprises Professor Andrei Linde with BICEP2 evidence supporting cosmic inflation, the first apparent images of primordial gravitational waves.

Bobby McFerrin uses audience participation at a World Science Festival event to demonstrate how instinctively people follow the pentatonic scale.

An excerpt from Richard Dawkins's lecture on Climbing Mount Improbable demonstrating how a complex eye can evolve through incremental steps. It answers the creationist irreducible complexity argument.

A clip from Channel 4's Inside Nature's Giants in which Richard Dawkins shows the recurrent laryngeal nerve of the giraffe during a dissection. The nerve takes a long detour down the neck and back up.

Mark Rober builds a third-generation glitter bomb trap and films it catching package thieves, with phone trackers and fart spray included. It shows the engineering behind the build and the comic payoff.

Ben Felix examines whether the well-known 4% retirement withdrawal rule holds up, drawing on academic papers. He argues that a safe rate may be closer to 2.7%, especially for early retirees.

A Fox News segment in which Jesse Watters interviews the moderator of the r/antiwork subreddit. The interview went badly for the moderator and led to the subreddit going private.

A short clip of Bill Gates demonstrating Visual Basic in 1991, showing drag-and-drop building of a Windows GUI.

Matt Parker explains the history behind NTSC television running at 29.97 frames per second rather than 30, tracing it to the backward-compatible addition of color. He walks through the arithmetic behind the odd ratio.

A Kurzgesagt animation on South Korea's record-low fertility rate and rapidly aging population. It explains why a demographic collapse looks hard to reverse and projects the population shrinking sharply by 2060.

Linus Tech Tips tests whether higher frame rates and refresh rates improve gaming performance, using Shroud and other players on aim and reaction tests at 60, 144 and 240Hz. The video is sponsored by Nvidia.

The opening sequence of the film Idiocracy, which satirically shows less intelligent people out-breeding more intelligent ones. It runs about three minutes.

The 1992 SIIA anti-piracy rap video Don't Copy That Floppy, warning kids against copying software, remastered and uploaded.

Sasa Juric explains what makes Erlang and Elixir suited to server-side systems, focusing on the BEAM concurrency model rather than syntax or ecosystem. He demonstrates processes, supervision, and fault tolerance.

Richard Feldman's elm-conf talk on designing models so that bugs from impossible application states cannot occur, using Elm's compiler and types. It demonstrates techniques for making invalid states unrepresentable.

Bret Victor's talk at CUSEC 2012 in which he argues that creators need immediate feedback and should organize their work around a guiding principle. He demonstrates live-coding and animation tools that show results as you type, and describes his own principle that creators must see what they are making.

CGP Grey narrates an animated adaptation of Nick Bostrom's Fable of the Dragon-Tyrant. The story uses a dragon that demands a daily toll of lives as a metaphor for aging and society's acceptance of death.

Part 1 of a lecture by physicist Albert Bartlett on the exponential function and its consequences for population growth, resource use and energy. It argues that steady growth rates quickly lead to enormous quantities.

Christian Schafmeister's Google Tech Talk on designing spiroligomer molecules and building Clasp, a Common Lisp on LLVM that interoperates with C++, to program molecular design. It covers the chemistry, automatic differentiation for force fields, and how the compiler is built.

Rich Hickey's Strange Loop 2011 keynote separates 'simple' (not intertwined) from 'easy' (familiar or near at hand) and argues that software complexity comes from complecting things. It offers a vocabulary for judging designs and abstractions.

Pete Hunt of Facebook and Instagram introduces React at JSConf EU 2013 and explains its design principles. He argues that separating templates from logic only separates technologies, not concerns, and makes the case for components.
