The Third Industrial Revolution: A Radical New Sharing Economy
Jeremy Rifkin, the economic theorist behind the phrase, argues that a new economic system is emerging from the convergence of three infrastructures: an ultra-fast 5G communication network, a renewable energy grid, and a driverless transportation network, all wired together through the Internet of Things. The film follows his case that this convergence is not just technological but structural, replacing centralized industrial-era ownership with a distributed, shared economy where access matters more than possession. Rifkin lays out why the current model, built on finite resources, slowing productivity, and widening inequality, cannot keep running as is, and treats climate change as the deadline forcing the transition rather than a side effect of it. He frames the shift as requiring more than new hardware: a change in political will and economic ideology strong enough to rebuild how societies manage power, movement, and goods. The film stays close to Rifkin's own framework throughout, presenting his road map as both diagnosis and prescription for what comes after the current industrial system.
The Map of Mathematics
Physicist Dominic Walliman draws the entire field of mathematics as a single map, then walks through it region by region. He starts with the earliest human counting systems and the invention of zero and negative numbers, before splitting the map into two territories: pure mathematics, covering number theory, algebra, geometry, and topology, and applied mathematics, covering probability, mathematical physics, and the tools behind engineering and computing. He traces how ideas move between the two sides, from complex numbers emerging out of impossible equations to trigonometry problems he flags and corrects afterward in his own errata. The map also marks the field's rougher edges, including a brief, later-retracted claim about what Gödel's Incompleteness Theorems mean for whether mathematics is invented or discovered. It's part of a series of subject maps Walliman has drawn for physics, chemistry, and computer science, and this one runs just over ten minutes as an orientation to where every branch of math sits relative to the others.
