A quarterly electronics and tools swap event is being launched at Berlin's c-base hacker space, focusing on right-to-repair and reuse principles. The event offers free seller spaces for trading electronics, computer equipment, and tools, with flexible payment options and minimal restrictions.
Physicists are exploring the chaotic nature of space-time near black hole singularities using new mathematical tools and the AdS/CFT correspondence. Recent research revisits the Mixmaster universe theory from the 1960s, suggesting that space near singularities experiences chaotic stretching and compression in multiple directions. These studies aim to reconcile general relativity with quantum mechanics and potentially reveal fundamental truths about space-time.
A photograph captures the final state of Richard Feynman's blackboard as it appeared at the time of his death in 1988 at Caltech. The historical image serves as a poignant snapshot of the renowned physicist's last academic thoughts and calculations.
A detailed exploration of building a low-cost synthetic aperture radar (SAR) system mounted on a drone, capable of capturing high-quality polarimetric images up to 1.5km range, weighing under 1kg, and costing around 800 EUR in components.
A discussion exploring the limits of determinism in classical mechanics, prompted by Sean Carroll's assertion that some classical systems lack unique predictable outcomes despite their rarity in real-world scenarios.
The Floppotron 3.0 is an upgraded computer hardware orchestra featuring 512 floppy drives, 4 scanners, and 16 hard drives that creates music through controlled mechanical noise. Using custom electronics and MIDI protocols, various computer hardware components are coordinated to produce musical tones and percussion sounds, consuming up to 1.15kW of power at peak performance.
