Researchers from the Artificial Life Lab Graz introduce the Primordial Particle System, where a simple motion law for self-propelled particles produces cell-like structures that self-reproduce and show life cycles.

Thomas Garrity discusses mathematical maturity, a concept mathematicians use for professional development, and how it can inform teaching, mentoring and careers. It was given at the IAS/PCMI Park City Mathematics Institute.

A 2017 documentary filmed at the Santa Fe Institute in which novelist Cormac McCarthy talks with SFI's David Krakauer. They discuss isolation, mathematics, character and the nature of the unconscious.

Conrad Wolfram argues that the part of math taught in schools, hand calculation, is tedious and mostly irrelevant to real mathematics. He proposes teaching math through computer programming so students can tackle real problems.

Part 2 of Richard Feynman's Messenger Lectures at Cornell, The Character of Physical Law, on the relation of mathematics to physics. He explains why understanding nature requires mathematics.

A 13-minute clip from This Week in Startups in which Chamath Palihapitiya describes venture capital as a Ponzi-like scheme driven by fees and inflated valuations among VCs.

Paul Buchheit, creator of Gmail and founder of FriendFeed, speaks at Startup School 08 about listening to users. He covers feedback, features, aiming for 100 happy users, and treating "that's impossible" as a statement of limited experience.

Mike Arrington of TechCrunch speaks at Startup School 2008 about how to get press coverage for a startup and how to respond to it.

A nearly five-hour live stream from Martin Shkreli with no description. HN mentions use it to show him working in Excel.

Practical Engineering explains what a black start is: restarting a power grid after total collapse. It shows why most plants need outside power to start and why rebuilding a synchronized grid is delicate and high-stakes.

An animated 11-minute tour of the whole field of mathematics as a single map, showing how pure and applied math and their sub-fields relate to each other.

hbomberguy investigates the modern flat earth movement and why people come to believe it. The video treats the community with a measured, humorous tone and looks at the social causes behind the belief.

The opening lecture of the How to Start a Startup course at Stanford, with Sam Altman covering ideas and products and Dustin Moskovitz discussing why to start a startup.

A BSidesLV 2013 talk from the Sixteen Colors project on archiving the ANSI and ASCII art scene. It traces the scene's evolution from BBSs to the NFO and IRC era.

The first lecture of MIT 6.042J Mathematics for Computer Science, taught by Tom Leighton, introducing mathematical proofs. It covers propositions, implication and basic proof methods.

A 16-minute Y Combinator Startup School talk in which Sam Altman lays out what makes a startup succeed. It covers building a product people tell friends about, exponential markets, real versus fake trends, and having an ambitious vision.

Brandon Sanderson's keynote on AI-generated art, arguing that the artistic process and the journey matter more than the finished product. He explains why he rebels against generative AI in creative work.

Jeff Geerling looks at a Sharp NEC commercial display with a slot for a Raspberry Pi Compute Module. It is a large screen without built-in smart TV features or tracking.

Matt Parker's Royal Institution talk based on his book Humble Pi, covering everyday mathematical mistakes and spurious patterns that went wrong in engineering and software. It mixes stand-up comedy with stories of coincidence and error.

A ten-minute clip of Richard Feynman describing how mathematicians and physicists differ in their interests and customs. He argues physics rests on visualizing and applying math rather than pure abstraction.

Joel Spolsky, founder of Fog Creek Software and StackExchange, speaks at Y Combinator's Startup School in 2012. He shares his perspective on building startups.

Gregory Chaitin is interviewed on Closer To Truth about whether mathematics is invented or discovered. He gives a nuanced view that ties the question to the nature of reality.
