John Gustafson presents posits, a proposed drop-in replacement for IEEE 754 floats that is simpler in hardware and more flexible in precision. The seminar includes a live demo and machine learning results.

A long recorded seminar in which Alan Kay discusses object-oriented programming, probably from the mid-1980s. He covers the original idea of objects, messaging and the work done at Xerox.

Rick Hartley gives a roughly two-hour live training on proper grounding in PCB design. He explains how energy actually flows in the space between conductors, and how that governs noise, EMI, return paths and signal reflections.

Synthetic organic chemist James Tour gives a lecture arguing that origin-of-life research is far from explaining how life began. The talk was published by the Discovery Institute and drew sharp criticism.

Biochemist Nick Lane gives a Royal Institution lecture arguing that the Krebs cycle is central to what makes cells alive, not just genetic information. He draws on the themes of his book Transformer to link metabolism to the origin of life, death, and aging.

Turing Award winner Michael Stonebraker gives the 2018 Donald B. Gillies Memorial Lecture at Illinois. He discusses the gap between academic research and industry problems, publishing incentives, and the influence of large industry users on research.

Jack Szostak's lecture covers how cellular life could have arisen from chemistry on the early Earth, starting from the odds of life elsewhere in the galaxy. It is part of a series on protocells and the RNA world.

A short Harvard Online animated lesson on how the mitochondrial electron transport chain works. It shows proton pumping and the machinery that drives ATP synthesis.

Nick Lane's Royal Institution lecture on the origin of life and why it is the way it is. It draws on his book The Vital Question and the alkaline hydrothermal vent theory of abiogenesis.

Robert Lustig of UCSF lectures on the biochemistry of sugar, arguing that fructose and lack of fiber drive the obesity epidemic via insulin. It is the widely viewed 90-minute talk that popularized the anti-sugar case.

Dr. Jason Fung lectures on why obesity became an epidemic since the 1970s, arguing insulin and hormones rather than calories drive weight gain. He explains why calorie counting fails and touches on low-carb eating and fasting.

A clip of psychologist Jordan Peterson lecturing on intelligence and IQ, covering how it is defined and its correlation with academic and work success.

Andres Gomez Emilsson of the Qualia Research Institute presents a model of DMT experiences using hyperbolic geometry and dynamical systems theory. He describes how different intoxication levels correspond to changing curvature and information content of experience.

Larry McEnerney of the University of Chicago Writing Program gives a graduate-student session on writing effectively. His core idea is that readers care about value to them, not the writer's thinking process.

Larry McEnerney of the University of Chicago Writing Program argues that good writing is defined by what readers value, not by rules or the writer's own ideas. He explains why academic habits fail outside academia and how to write so readers find the work valuable.

Jonathan Haidt's Hayek Lecture at Duke argues American universities pursue two potentially incompatible sacred values, truth and social justice. He discusses campus conflict, honor, dignity and victimhood cultures, and viewpoint diversity.

A Bell Labs film in which Dr. J.N. Shive uses a mechanical wave machine to demonstrate reflection, standing waves, resonance and impedance matching. He includes some equations but relies mostly on real-world examples a layperson can follow.

Cognitive scientist George Lakoff lectures on how political debates are framed through language and metaphors tied to values, and on the moral worldviews behind progressive and conservative politics. It was given in 2005 at UC San Diego.

Douglas Hofstadter's Stanford Presidential Lecture argues that analogy is the core of cognition, illustrating how concepts, categorization and thought arise from analogy-making.

Dr. Roger Seheult of MedCram reviews the benefits of sunlight beyond vitamin D, covering the solar spectrum, circadian rhythm, melatonin and infrared light. The lecture runs nearly two hours with timestamps.

The first episode of John Vervaeke's lecture series on the modern meaning crisis, tracing its history through philosophy, cognitive science, religion and psychology. It introduces the series and its themes.

Historian and journalist Gwynne Dyer gives a long UBC talk on how climate change will reshape international politics. He covers food, borders, refugees and the possibility of unilateral geoengineering by affected nations.

Cardiologist Dr. Pradip Jamnadas lectures on the rationale for dietary restriction and fasting, covering insulin resistance, glucose intolerance, and low-carb eating over about 81 minutes.

Robert Sapolsky's lecture on how the body's stress response, evolved for short-term physical emergencies, harms long-term health when triggered by psychological stressors. It was given as the inaugural Fenton-Rhodes Lecture.

Jean-Marc Jancovici lectures at ENS Paris on whether energy use, jobs and growth can all be preserved. He argues for a physical approach to economics, since resource depletion and climate limits make perpetual GDP growth unrealistic.

Robert Lustig of UCSF updates his sugar talk, arguing that fructose and processed foods drive obesity and metabolic syndrome through their endocrine effects. It is a roughly 90-minute university lecture.

Neuroscientist Anil Seth gives a Royal Institution lecture on the science of consciousness. He separates conscious level, content and self, and argues that experience arises from the brain's predictive inference.

A Virginia Tech presentation by Sid Smith about collapse, fossil fuels and overshoot, arguing that industrial civilization faces a decline and how one might live with that. It was later expanded into a video series.

Daniel Dennett's Royal Institution lecture on whether the brain is a computer and where its software comes from. He argues that minds are built by evolution and culture, with competence arising without comprehension.

A lecture by Prof. Thomas Seyfried arguing that cancer is primarily a metabolic disease rather than a genetic one. It covers the Warburg effect, mitochondrial damage and implications for therapies.

A Ninja Nerd whiteboard lecture on the Moderna, Pfizer/BioNTech and AstraZeneca COVID-19 vaccines. It covers how each works, the preclinical and phase I-III trial process, and Operation Warp Speed.

Energy scholar Vaclav Smil argues that global energy transitions are slow and that renewable targets should not rest on wishful thinking. He appraises how energy dependencies are likely to change and asks for using much less.

Dr. Russell Barkley explains how different ADHD medications work and how they differ from one another, in a short clip.

Michael Levin presents his lab's work on how cellular collectives use bioelectric networks to make anatomical decisions. Topics include pattern memories, regeneration and synthetic living organisms.
