The emergence of this kind of professional involvement in the adjustment of technologies to professional practice is a crucial topic for the CSCW field because, as Star and Strauss wrote, “(...) the systematic exclusion of certain forms of work mean a displacement of that work and a distortio...
If you had a "bigger eye," you could collect more light from the object and create a brighter image, and then you could magnify part of that image so it stretches out over more pixels on your retina. Two pieces in a telescope make this possible: The objective lens (in refractors) or...
2. The sensation of perceiving light; brightness: a sudden light that made me blink. 3. a. A source of light, especially a lamp, a lantern, or an electric lighting fixture: Turn out the lights when you leave. b. The illumination derived from a source of light: by the light of the...

The second lens doesn't sort out that problem. So binoculars have a pair of prisms (large wedges of glass) inside them to rotate the image through 180 degrees. One prism rotates the image through 90 degrees (flips it onto its side), then the next prism rotates it through another 90 ...
You checked out the roof prism pair on the first page. Here's its main competition: Porro prism binoculars. © HowStuffWorks 2011 Binoculars may seem like simple technology, but it's a little more complicated than putting a couple of magnifying glasses to your eyes. Without prisms in the ...
Snell’s Law governing refraction, where n is the index of refraction, and θ is the angle of incidence of the light in either material 1 or material 2: Figure 2: A ray of light refracting through a flat surface, bending in the process. The dotted line represents the normal to the ...
