Scott Manley looks at SpinLaunch, which aims to throw launch vehicles out of a spinning launcher at hypersonic speed. He covers its recent Mach 1 test of a one-third scale launcher and the engineering problems that remain.

Thunderf00t's second video critiquing SpinLaunch, the company that proposes flinging rockets and payloads into space with a giant centrifuge. He argues the idea is physically unworkable.

Thunderf00t critiques SpinLaunch, the startup that proposes flinging payloads to space with a giant centrifuge. He argues the physics and engineering do not hold up.

Chuck Spinney, a long-time associate of John Boyd, presents Boyd's thinking on the OODA loop and evolutionary epistemology. The talk runs about two and a half hours and includes Q&A.

Freespin is a demo that runs on a Commodore 1541 floppy drive. It makes sound by vibrating the drive head and video by toggling the serial bus lines, and it keeps running after the C64 that booted it is disconnected.

Dennis Gustafsson, creator of Teardown, presents how he parallelized the physics solver for an upcoming game, followed by a Q&A. The talk was given at the Better Software Conference 2025.

ScienceClic gives a 15-minute animated introduction to quantum field theory, covering fields, spin, conserved quantities, the standard model and interactions.

Steve Mould shows Spintronics, a set of mechanical components such as resistors, capacitors and transistors linked by chains, that give an intuitive feel for how electrical circuits work.

Tom Scott makes the difference between a million and a billion dollars tangible by using distance on a road trip instead of volume. The drive makes the scale of a billion intuitively felt.

Tim Dodd's hour-long deep dive on how rocket engines start, from solid motors to liquid engines. It covers thermal conditioning, spin-up, ignition methods, starting in space, and a step-by-step RS-25 startup.

A one-minute Fortnite parody of Apple's 1984 ad, released when Epic Games challenged the App Store and Apple removed Fortnite from iOS. It frames Apple as the monopolist.

A hobbyist build-and-experiment video on rotating detonation engines (RDEs), where a continuous detonation wave spins around an annular chamber. The creator 3D prints parts and tests a small engine, while being candid about uncertainty over whether a true rotating wave was achieved.

Boston Dynamics shows the electric Atlas autonomously moving engine covers between containers and a sequencing dolly. It uses an ML vision model and grasping policy with no teleoperation or prescribed motions.
