Earth is often described as a circle or an oval, but it is neither. As the planet spins more than 1,000 miles per hour at the equator, it develops a slight bulge around its middle. The result is what ...

In 2026, the world of mechanical keyboards accessories continues to evolve from a niche hobby into a mainstream passion.

Skoltech researchers proposed doping the cathode material with high-valent tantalum and discovered that adding 0.5 mole percent of tantalum oxide (Ta₂O₅) reduced the rate of battery capacity decay per ...

After introducing for Google Search in May, the gradient ‘G’ icon will now be used across the company. Initially, that G icon where the four colors bleed into each other was just for Search. The ...

Abstract: In this paper we propose a novel method of estimating vanishing point by spherical gradient. In contrast with the conventional methods in which vanishing point is estimated from lines, the ...

Bodies of water such as the ocean tend to feature gradients in density due to variations of temperature or salinity. Global warming is acting to increase this stratification. This work demonstrates ...

Abstract: A semi-analytical method is presented for the design of gradient index (GRIN) flat lenses. Closed-form expressions are derived to define the refractive index distribution of the lens, for ...
