Adam Neely explains what perfect (absolute) pitch is, how it differs from relative and quasi-absolute pitch, and why he would not want it. He covers its drawbacks, including drift with age.

Rick Beato argues that adults cannot develop true perfect pitch, which he ties to critical-period brain plasticity and language acquisition. He says it can only be developed in young children, and discusses the research behind this.

Destin of Smarter Every Day learns to ride a bicycle whose steering is reversed, taking about eight months, and compares it with how his young son learned much faster. It illustrates knowledge versus understanding and brain plasticity in adults versus children.

An RSA Animate summary of Iain McGilchrist's lecture on the divided brain, arguing the brain's two hemispheres attend to the world differently and that this has shaped culture and society.

Veritasium explores why time seems to speed up as we age, covering chronoception and several competing explanations beyond the common proportional-theory argument.

Johns Hopkins APL shows Les Baugh, a bilateral shoulder-level amputee, controlling two Modular Prosthetic Limbs by thought after a short training period. Nerves rerouted to his chest drive the arms.

Neuroscientist Karl Friston gives a 15-minute talk on the free energy principle, covering Markov blankets, Bayesian model evidence and global brain theories.

An artist describes discovering she has aphantasia, the inability to form mental images, and how it affects her work. She asks viewers about their own visualization.

Tom Scott features Kurtis Baute inside a sealed homemade biodome as carbon dioxide builds up, showing how stale air with elevated CO2 affects cognitive function. Sources include studies on CO2 and cognitive scores.

A short clip of Robert Sapolsky on how social hierarchy generates chronic stress, drawing on baboon research. It links rank-related stress to heart health and life expectancy.

Rick Beato discusses a theory of why some children develop perfect pitch, based on early exposure to music. He draws on his experience with his own children.

Der8auer tours Hetzner's test lab and shows a custom AM5 server motherboard with the CPU socket rotated 90 degrees, built for rack airflow in their AX52 servers.

Scott Manley analyzes the idea of putting data centers in orbit, prompted by Lumen Orbit's funding. He examines the claimed advantage of constant solar power against launch cost, cooling and mass.

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.

Vsauce explores qualia and whether different people experience colors the same way. It draws on color blindness, Mary's room, the explanatory gap and subjective experience.

Footage of FAA altitude chamber hypoxia training for pilots in which a participant passes out from oxygen deprivation. It shows how quickly and subtly cognition fails at altitude.

A KRAZAM comedy sketch in which a character recites reassuring affirmations to site reliability engineers, satirizing on-call and outage culture.

Neuroscientist Anil Seth argues in this TED talk that perception is a controlled hallucination: the brain constantly predicts the world and our shared agreement is what we call reality. He also touches on the construction of the self.

Solomon Hykes shows Docker to the public for the first time in a five-minute lightning talk at PyCon 2013. It demos Linux containers and the simplicity of a Dockerfile.

A student interviews Kirsten Carlson, who does not have an internal monologue, and she answers questions about how she thinks. The video grew out of a viral article about people lacking inner speech.

Psychology professor Lisa Feldman Barrett presents her research on what emotions are, arguing that the brain constructs them rather than reading them off faces. She says this means we have more control over our emotions than we think.

A video arguing that exercise matters for the brain as much as the body, linking movement, the nervous system and BDNF to learning and memory. It draws on research connecting complex movement to brain development.
