Refrigerators and air conditioners that operate on vapor compression technology have a fundamental flaw. They are inefficient, rely on hydrofluorocarbons (HFCs) that contribute to greenhouse gas emissions, and are not easily downsizable. However, researchers have developed solid-state alternatives to vapor compression that can overcome these issues. One such alternative is the electrocaloric effect, which relies […]

In this web content, Dong and Song have proved a conjecture formulated by Huisken and Ilmanen in 2001. The conjecture states that as the mass of a space approaches zero, its curvature must also approach zero. However, this scenario is complicated by the presence of bubbles and spikes. Dong and Song have shown that these […]
Apple continues to heavily promote Swift as the preferred programming language for its platforms, but Objective-C still holds a significant presence. A recent study shows that Objective-C remains the core language of iOS, with most apps using it directly or indirectly. Additionally, many frameworks shipped on macOS are still written in Objective-C. An interesting trick […]

The author acknowledges their love for JavaScript, CSS, and JSX HTML, highlighting the rule of least power in web development. They emphasize choosing the least powerful language for a given purpose, favoring HTML over CSS and then CSS over JS. While JS is versatile, it can also break, fail to load, and exclude certain users. […]
The author describes their journey in creating a tiny volumetric display. They initially had the idea to create a flickering candle-like effect using a persistence-of-vision display, but realized it would require too much supporting machinery. They then came up with the idea to create a spinning display with a small motor and battery. They used […]
