A PBS Space Time episode on how the Higgs mechanism gives particles mass, prompted by Fermilab's heavier-than-expected W boson measurement. It goes beyond the usual pop-science treatment without heavy math.

PBS Space Time explains the Higgs field and how the Higgs mechanism gives particles mass within quantum field theory. It is a ten-minute overview for a lay audience.

Psychologist Robert Epstein presents a Stanford EE380 colloquium on how internet algorithms such as search rankings can manipulate opinions, purchases and votes at massive scale. He also describes a new monitoring system for tracking such influence.

Hyrum Wright shares lessons from five years of mass code migrations in Google's huge C++ codebase. He covers why to migrate, how hard it really is, and how Google updates core libraries and their users continually.

Arend Schwab demonstrates a research bicycle, the two-mass-skate design, that balances itself without gyroscopic effects or trail. It challenges the common explanations for why a moving bicycle stays upright.

A PyData London 2018 talk on how JPMorgan scaled its Athena Python platform over ten years to about 35 million lines of code and thousands of developers. It covers infrastructure, tooling and culture for analytics and visualization at that scale.

Louis Rossmann opens a new MacBook Air and reacts to its cooling design, where the fan does not appear to be thermally connected to the CPU heatsink. He calls it placebo cooling.

Thunderf00t argues that Zero Mass Water's solar-powered atmospheric water generator is essentially a dehumidifier with solar panels. He critiques its economics and physics, especially in arid places.

Official trailer for Eugene Jarecki's 2012 documentary The House I Live In, an investigative look at America's war on drugs and its effect on the criminal justice system. It won the Grand Jury Prize at Sundance.

John Oliver interviews Edward Snowden about NSA surveillance, including street interviews showing people have not thought about what the government can see. The segment famously frames the issue through private photos.
