A one-minute clip where an AM radio station can be heard through the arcing of a high-power transmitter tower.

CGP Grey's animated adaptation of The Dictator's Handbook, explaining how rulers stay in power by keeping a small group of key supporters happy rather than ruling fairly. It lays out selectorate theory and how resources shape regimes.

Alan Kay's 2015 talk on the power of simplicity, arguing that systems become simpler by building on more sophisticated fundamental building blocks and that big research horizons drove invention at Xerox PARC. It ranges across computing, tools and scaling software.

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.

3Blue1Brown presents the Triangle of Power, an alternate notation that unifies powers, logarithms and roots in a single triangular symbol. The video shows how the inverse operations relate and how the notation could help.

Alex Russell's Chrome Dev Summit 2016 talk on building web experiences that work on slow, flaky networks and low-power devices. It argues developers should focus on the performance of real-world mobile hardware rather than desktop machines.

Michael Shellenberger argues in a TEDx talk that solar and wind need huge amounts of land and mining, and says nuclear power is a better path to protecting both the climate and nature.

The opening lecture of Ian Shapiro's Yale course Power and Politics in Today's World, which examines political dynamics and institutions over the past quarter century, including inequality, declining unions and new forms of authoritarianism.

An Al Jazeera English People & Power investigation from 2010 into safety problems with the Boeing 737NG, featuring whistleblowers on cracking parts, hand-made structural components and an alleged cover-up.

CGP Grey, adapting The Dictator's Handbook, explains how rulers keep power and why succession causes trouble when they die. It is the sequel to his video on the rules for rulers.

Bobby Powers presents Mesh, a drop-in malloc replacement that eliminates memory fragmentation in unmodified C/C++ programs by compacting memory. The talk covers how it works despite C's fixed object addresses, and its benefits for programs like Redis.

Aamer Rahman of Fear of a Brown Planet delivers a stand-up routine on so-called reverse racism, arguing about power imbalance and why criticism of a dominant group is not equivalent to racism.

Tech Ingredients builds a larger solar-powered desiccant air conditioner that uses a calcium chloride liquid desiccant with evaporative cooling to cool their lab. The video includes the engineering calculations.
