Curricle. A curricle is a light two-wheeled carriage drawn by two horses abreast. Usually open with a falling hood, it seats two people, plus a liveried groom on a seat or small platform between the rear springs—whose weight might be required to properly balance the carriage. Curricles are harnessed with a pole between the horses, and have an ...
Vector graphics. Vector graphics are a form of computer graphics in which visual images are created directly from geometric shapes defined on a Cartesian plane, such as points, lines, curves and polygons. The associated mechanisms may include vector display and printing hardware, vector data models and file formats, as well as the software ...
Heron's fountain is a hydraulic machine invented by the 1st century AD inventor, mathematician, and physicist Heron (or Hero) of Alexandria . [1] Heron studied the pressure of air and steam, described the first steam engine, and built toys that would spurt water, one of them known as Heron's fountain. Various versions of Heron's fountain are ...
Summary. Description. Standard Model of Elementary Particles.svg. English: Standard model of elementary particles: the 12 fundamental fermions and 5 fundamental bosons. Brown loops indicate which bosons (red) couple to which fermions (purple and green). Please note that the masses of certain particles are subject to periodic reevaluation by the ...
Trip valve gear. Trip valve mechanisms are a class of steam engine valve gear developed to improve efficiency. The trip mechanism allows the inlet valve to be closed rapidly, giving a short, sharp cut-off. The valve itself can be a drop valve or a Corliss valve . Trip valve gear was applied to larger stationary engines.
Spark chamber demonstration. A spark chamber is a particle detector: a device used in particle physics for detecting electrically charged particles.They were most widely used as research tools from the 1930s to the 1960s and have since been superseded by other technologies such as drift chambers and silicon detectors.
PostScript is a page description language run in an interpreter to generate an image. [ 6 ] It can handle graphics and has standard features of programming languages such as branching and looping. [ 6 ] PDF is a subset of PostScript, simplified to remove such control flow features, while graphics commands remain.
Cracking your neck too hard or too often could lead to: Pinched nerve. Stroke. Blood clot. Osteoarthritis. While these are low risk, the risk is higher for individuals who have conditions such as ...
