Lex Fridman interviews physicist Roger Penrose on consciousness, the limits of computation, quantum mechanics and his cyclic cosmology. It covers his views on AI and the big bang.

Physicist Roger Penrose and philosopher William Lane Craig discuss the origin of the universe on the Unbelievable? show. Topics include Penrose's three realms of reality, conformal cyclic cosmology and whether fine tuning points to a creator.

Clip from Lex Fridman's podcast with Roger Penrose in which Penrose argues that consciousness is not a computation. He discusses Godel-style arguments and the possible role of quantum effects in microtubules.

A 2020 UC San Diego event with Roger Penrose and Stuart Hameroff presenting their Orch OR theory that consciousness arises from quantum processes in brain microtubules, followed by a conversation with Roger Bingham.

PBS Space Time examines Roger Penrose's idea that consciousness arises from quantum processes in the brain, and reviews new evidence about microtubules. It ends with an estimate of what replicating consciousness would demand.

A short 2013 video in which Roger Ver says Mt. Gox's withdrawal delays are not caused by a lack of liquidity. Mt. Gox collapsed months later, and the description carries a later update and apology.

Seven-minute footage of Fred Rogers testifying before a US Senate subcommittee in 1969 to defend federal funding for the new Corporation for Public Broadcasting. A skeptical Senator Pastore starts out abrasive and is won over during Rogers' brief, calm testimony.

PBS Space Time explains Roger Penrose's conformal cyclic cosmology, in which the far future of our universe becomes the big bang of the next. It explores what could come after the universe ends.

PBS Space Time explains what happens as you approach and cross a black hole's event horizon, using Penrose diagrams and light cones as the tool for understanding spacetime there.

A DEF CON 23 talk by Marc Rogers and Kevin Mahaffey walking through the architecture of the Tesla Model S, what Tesla got right and wrong, and how the interconnected systems can be hacked. It also covers the data the car collects.

Veritasium explores what general relativity says about black holes, white holes and wormholes, with help from physicists Geraint Lewis and Juan Maldacena. It introduces Penrose diagrams and the idea that other universes may be implied.

An Isaac Arthur episode on civilizations in the dark, post-stellar universe, including black hole farming, accretion disks and the Penrose process as energy sources.

Veritasium explains how Penrose tilings and quasicrystals overturned the belief that 5-fold symmetry and non-periodic crystals were impossible, including an interview with Paul Steinhardt.

Joe Scott takes a serious look at space sunshades as a climate fix, asking how big they would need to be, what they would cost and whether they would work. He draws on Roger Angel's paper and launch options.

A one-minute clip from Who Framed Roger Rabbit in which a swinging pendant lamp is bumped and keeps flailing, showing animators' attention to detail.

A six-minute journey through the layers of a neural network using Deep Dream, with each frame fed back into the network starting from random noise and the targeted layer changing every four seconds. It is set to downtempo music.

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.

Modern Vintage Gamer looks at OpenLara, an open source Tomb Raider engine, running on the Game Boy Advance. The video explains how the port achieves playable speeds on the GBA's slow ARM CPU, with input from the developer XProger.

MedCram's Dr. Roger Seheult summarizes a discussion with Dr. Michael Mina on cheap, paper-based at-home COVID-19 antigen tests. It explains why lower sensitivity can still work well for screening infectious people.

Google I/O 2011 session by Ray Cromwell and Philip Rogers on writing 2D and 3D games with HTML5 and GWT. It covers porting game libraries and physics engines, sharing code with Android, and publishing to the Chrome Web Store, and showcases the ForPlay library.

A very short microscope clip of a neutrophil chasing a Staphylococcus aureus bacterium, originally from David Rogers at Vanderbilt University. It is a widely reposted piece of immune-system footage.
