Over the last several years, the study of working memory (WM) for simple visual features (e.g., colors, orientations) has been dominated by perspectives that assume items in WM are stored independently of one another. Evidence has revealed, however, syst
A plasma screen is similar to an LCD, but each pixel is effectively a microscopic fluorescent lamp glowing with plasma. A plasma is a very hot form of gas in which the atoms have blown apart to make negatively charged electrons and positively charged ions (atoms minus their electrons). These...

The laser system is claimed to offer twice the range of even the brightest LED. Its laser diodes create a bright blue light that has to be filtered by phosphor converters to make it white and harmless to the human eye. In the future, Audi engineers...
Photo: Modern Geiger counters often have the two parts (detecting tube and associated electronics) packed into a single unit, with a digital display for easy reading. This is a Mirion ADM-300 with two built-in Geiger counters for detecting beta and gamma radiation and (inset) its LCD ...
Input: Keyboard: About 40 tiny plastic keys with a rubber membrane underneath and a touch-sensitive circuit underneath that. Processor: A microchip that does all the hard work. This does the same job as all the hundreds of gears in an early calculator. Output: A liquid crystal display (LCD...
