A CCD (charge-coupled device) camera is essentially a grid of photometers, simultaneously measuring and recording the photons coming from all the sources in the field of view. Because each CCD image records the photometry of multiple objects at once, various forms of photometric extraction can be performed on the recorded data; typically ...
2009 Nobel Prize in Physics laureates George E. Smith and Willard Boyle, 2009, photographed on a Nikon D80, which uses a CCD sensor. The basis for the CCD is the metal–oxide–semiconductor (MOS) structure, [2] with MOS capacitors being the basic building blocks of a CCD, [1] [3] and a depleted MOS structure used as the photodetector in early CCD devices.
Some liken CCD to slide film (also known as positive film) and CMOS to negative film. [36] While there were larger CCD sensors made for interchangeable-lens cameras, such as the Leica M9, CCD sensors in fixed-lens cameras maxed out at 2/3″ (1/1.5″). Premium compact cameras of the time contained sensors around 1/1.7″ in size, whereas entry ...
The valley of Someșul Mare has much auriferous alluvium that, until the early 20th century, were brought to the surface using traditional tools. Specialists say that in the Someșul Mare were found grains of gold of 21 carats. [10] The Someș drains a basin of 18,146 km 2 (7,006 sq mi), [6]: 22 of which 15,740 km 2 (6,080 sq mi) in Romania.

By 1970, a calculator could be made using just a few chips of low power consumption, allowing portable models powered from rechargeable batteries. The first handheld calculator was a 1967 prototype called Cal Tech, whose development was led by Jack Kilby at Texas Instruments in a research project to produce a portable calculator. It could add ...
