Physicist Al Bartlett's well-known lecture on the arithmetic of exponential growth, applied to population, energy consumption and resource depletion. He argues that steady percentage growth cannot be sustained on a finite planet and that most public discussion ignores this.

A recording of physicist Albert Bartlett's well-known lecture on the arithmetic of exponential growth, applied to population and energy use. He argues that steady percentage growth in a finite world cannot continue and sneaks up suddenly.

CGP Grey argues that aging and death are a problem worth defeating, using a short animated essay. It is part of a pair with a follow-up from Kurzgesagt.

A Kurzgesagt animated explainer on whether aging could be cured within our lifetimes, made with Lifespan.io and the LEAF foundation. It introduces the idea of treating aging as a medical problem.

Physicist Albert Bartlett's full-length lecture on how steady exponential growth in population and energy use collides with finite resources. It uses examples like bacteria in a bottle and covers peak oil.

Harvard geneticist David Sinclair discusses his book Lifespan at Google. He covers the biology of aging, lifestyle interventions and possible future ways to slow or reverse it.

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.

Ramesh Raskar presents femto-photography, a technique that captures a trillion frames per second, fast enough to show light itself moving through a scene. He discusses possible uses such as cameras that see around corners or inside the body.

A PBS NewsHour report on a viral compilation of local TV anchors reading identical scripts, which raised concerns about Sinclair Broadcasting mixing partisan opinion into local news. It also covers Sinclair's reach and its bid to grow larger.

Robert Erdmann, a materials scientist at the Rijksmuseum, gives a PyCon keynote on the ultra-high-resolution imaging of Rembrandt's Night Watch. He covers the automated gantry camera system, the Python software that drives it, and the large volumes of image data involved.

Inventor Mary Lou Jepsen demonstrates using red light and sound to see inside the body and brain, aiming at tumor detection and neural activity measurement, and potentially a cheaper wearable MRI replacement.

TED talk by biochemist Cynthia Kenyon on how a simple genetic mutation can double the lifespan of the worm C. elegans, and what that suggests about extending healthy human life.

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.

Explains the proposed NASA JPL plan to use the Sun as a gravitational lens, sending solar sail craft to its focal region to image an exoplanet's surface. It covers the distances involved, how imaging with the Sun would work and the mission design.

Hans Rosling's TEDxSummit talk asks whether some religions have higher birth rates and how that affects population growth. He charts data across time and religions and reaches a surprising conclusion about fertility.

Rhonda Patrick of FoundMyFitness makes a case for isothiocyanates such as sulforaphane from cruciferous vegetables and broccoli sprouts. It covers cancer, aging, heart disease, brain and behavior, and neurodegeneration, with chapter timestamps.

Psychiatrist Daniel Amen discusses lessons from 83,000 brain scans, arguing that brain activity patterns relate to psychological symptoms and that you can improve your brain.

A short compilation of dozens of local news anchors at Sinclair-owned stations reading the same scripted promo about biased and fake news. It went viral in 2018 as an example of centralized media messaging.

MIT Media Lab shows an imaging system capturing a trillion frames per second, fast enough to film light pulses travelling through objects in slow motion.

A Rheinmetall promo clip of its truck-mounted Skynex air defence system engaging a swarm of eight small drones with a 35mm revolver gun.

A Last Week Tonight segment on how tobacco companies sustain profits by pushing sales overseas. It covers suits against countries like Australia over plain packaging through trade-deal arbitration.

PBS Space Time explains the proposal to use the Sun's gravity as a giant lens, sending a train of small light-sail spacecraft to the focal point roughly 550 AU out. It covers how such a telescope could image exoplanets in surprising detail and the engineering challenges involved.

A long Portal podcast episode in which Bret Weinstein tells Eric Weinstein the story of his lab mice telomere work, the prediction behind it, and what it means for science and aging.

A Veritasium video on the logistic map, showing how a simple population equation leads to chaos and bifurcation. It connects the idea to convection, neuron firing and the Mandelbrot set, with interactive animations.

Excerpts from Linus Torvalds's DebConf 14 talk on why desktop Linux struggles. He covers application distribution, distros breaking backwards compatibility, wasted package management effort and how Windows does app distribution better.
