Engineer Builds Camera That Ignores Perspective, Sees Through Walls

Shane Wighton, the creator of the YouTube channel Stuff Made Here, has engineered an incredible camera that defies perspective and can even see through walls. Instead of a traditional lens, this camera uses a sophisticated mechanical system to scan a scene one pixel at a time, building a complete image. By utilizing a spinning gantry and a precisely controlled mirror, the camera moves in 3D space, capturing multiple views to reconstruct the final image. This allows it to create images without perspective, achieve reverse perspective, and even see around objects, showcasing an astonishing feat of engineering and imaging technology.

The Royal Navy's Century-Long Battle Against Lightning Rods

In the mid-18th century, Benjamin Franklin elucidated the nature of lightning and advocated for lightning rods. Yet, a century later, the British Navy remained unconvinced. Dr. William Snow Harris invented a shipborne lightning rod system and demonstrated its principles through an ingenious booklet with interactive, gold-leafed illustrations. Despite his decades-long efforts, backed by data, experiments, and key lightning incidents, the Navy resisted. Only after political maneuvering was Harris finally successful in 1842, getting his lightning rods installed on all Royal Navy vessels. His victory was short-lived, however; the advent of ironclad ships rendered them obsolete. This story highlights the enduring struggle between scientific discovery and political decision-making.

Modules Begone: A New Programming Paradigm Based on a Global Function Database

2025-04-04

This article proposes a revolutionary programming paradigm: abandoning modules in favor of a global function database. All functions have unique names and rich metadata, stored in a searchable key-value database. This simplifies open-source contributions (contributing a single function is sufficient), eliminates the module partitioning problem, and facilitates function lookup and reuse. The author argues that this approach is more beneficial for the development and maintenance of large programs and proposes specific implementation ideas and extensions, such as function rating and peer review mechanisms.

Pushing the Limits: A New Measurement of Superheavy Nuclei Half-Life

Researchers have pushed the limit of known half-lives of superheavy nuclei by two orders of magnitude by measuring the half-life of a neutron-deficient rutherfordium isotope. The extremely short half-life was measured by exploiting the longer half-life of excited states, providing insights into nuclear fission. The team bombarded a lead target with titanium-50 ions to create rutherfordium-252, measuring its half-life in excited and ground states as 13 microseconds and 60 nanoseconds, respectively. This challenges existing theoretical models and opens avenues for studying heavier superheavy elements.

Sensirion SGP41 TVOC Sensor Accuracy Test: Relative Changes, Not Absolute Values

AirGradient conducted accuracy and precision tests on the Sensirion SGP41 TVOC sensor used in their air quality monitors. The tests revealed that the sensor effectively tracks relative changes in TVOC levels – detecting increases or decreases – but cannot provide precise absolute values. This is due to limitations inherent in low-cost VOC sensors, including lack of specificity, cross-sensitivity, environmental sensitivity, and baseline drift. While the sensor cannot precisely measure TVOC concentrations, it still offers practical value in identifying TVOC sources and for environmental monitoring. Future testing by AirGradient will explore sensor performance under various conditions to further understand its capabilities and limitations.
