In briefColin Smith introduces Structure and Interpretation of Classical Mechanics and his Clojure port, sicmutils. He shows how higher-order functions and a symbolic algebra system can represent Lagrangian mechanics.
In briefVerge Science's pilot of its Trial & Error series follows amateur scientist Jon Larsen on a hunt for micrometeorites. It shows how tiny space rocks can be found on rooftops and confirmed under a microscope.
In briefIsaac Arthur examines options for colonizing Venus, from vast floating habitats in the temperate upper atmosphere to full terraforming of the planet. It is a long-form speculative futurism episode in his solar system colonization series.
In briefRaw 500 fps footage from Camera E-8 on the launch tower for the Apollo 11 Saturn V liftoff, transferred in HD from the 16mm original. More than eight minutes of film covers about 30 seconds of real time.
In briefBen Krasnow of Applied Science demonstrates an X-ray fluorescence gun that measures chemical composition, tears it down, analyzes its failure, and discusses a new XRF technology appearing on eBay.
In briefOlympic track cyclist Robert Forstemann tries to pedal hard enough to power a 700 W toaster and toast a slice of bread. The film frames it as a comparison of how much energy people consume versus how much they can generate.
In briefEveryday Astronaut takes a tour of SpaceX's Starbase with Elon Musk as guide. Topics include the Raptor engines, launch escape systems, the heat shield and the first orbital test.
In briefNathan Kutz presents the spatio-temporal dynamics of rotating detonation rocket engines, including combustion fronts that behave like solitons. He shows a bifurcation analysis of a multiscale model that captures the main features.
In briefSmarter Every Day host Destin Sandlin tries to hover a helicopter and finds it very hard. The video shows how the constant coordinated corrections across several control axes feel at first and how learning makes them automatic.
In briefA Capella Science parody of Ed Sheeran's Shape of You, rewritten about molecular bonding and orbitals and sung a cappella.
In briefThe US Chemical Safety Board's updated animation of the 2005 BP Texas City refinery explosion, which killed 15 workers. It was released ahead of a process safety training application.
In briefA 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.
In briefBranch Education explains how Starlink works, from the ground dish and satellites to phased-array beam steering and data routing. Animations cover how a beam stays connected to a satellite moving at 27,000 km/h.
In briefA detailed 40-minute explanation of the ultraviolet catastrophe, covering Rayleigh and Jeans' classical treatment of blackbody radiation and Planck's quantum hypothesis. It follows the Eisberg and Resnick textbook treatment.
In briefScott Manley explains rotating detonation engines, how they differ from pulsed detonation engines, and why thermodynamics predicts they beat traditional jet and rocket engines.
In briefA roughly four-and-a-half-hour Lex Fridman podcast conversation with Stephen Wolfram about his Wolfram Physics Project and a fundamental theory of physics, computation, life and the universe.
In briefTom 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.
In briefLex Fridman interviews mathematician and economist Eric Weinstein about science, mathematics, and society. The conversation ranges across physics, academia, AI and job displacement.
In briefA hands-on comparison of how jet fuel, diesel, heating oil, kerosene, avgas and gasoline burn and what color they are. It shows that gasoline ignites more easily than jet fuel.
In briefTech Ingredients builds a larger solar-powered desiccant air conditioner that uses a calcium chloride liquid desiccant with evaporative cooling to cool their lab. The video includes the engineering calculations.
In briefA short video from a blacksmith, who heats and bends steel to rebut the claim that jet fuel could not weaken the steel in the World Trade Center. It is delivered with a lot of attitude.
In briefA PBS Space Time episode asking whether the universe's information can ever truly be lost, tying quantum mechanics, determinism and black holes together. It sets up the black hole information paradox.
In briefKurzgesagt explains black hole stars, a hypothesized kind of giant star with a black hole at its core that could be a route to early supermassive black holes.
In briefScott 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.
