2. Liquid-mirror telescope - Wikipedia

   en.wikipedia.org/wiki/Liquid-mirror_telescope

   The force of gravity (red), the buoyancy force (green), and the resultant centripetal force (blue) In the following discussion, represents the acceleration due to gravity, represents the angular speed of the liquid's rotation, in radians per second, is the mass of an infinitesimal parcel of liquid material on the surface of the liquid, is the distance of the parcel from the axis of rotation ...

3. Liquid-mirror space telescope - Wikipedia

   en.wikipedia.org/wiki/Liquid-mirror_space_telescope

   Balloon: A balloon with a reflective liquid on the inside is spun up and deforms itself into a parabolic shape. A flat mirror on the inside reflects light to the concave surface. Continuous-acceleration rocket. A spacecraft is accelerated by an ion thruster or something similar, which produces a constant linear acceleration for a long period of ...

4. Foundation (cosmetics) - Wikipedia

   en.wikipedia.org/wiki/Foundation_(cosmetics)

   Foundation is a liquid, cream, or powder makeup applied to the face and neck to create an even, uniform color to the complexion, cover flaws and, sometimes, to change the natural skin tone. Some foundations also function as a moisturizer , sunscreen , astringent or base layer for more complex cosmetics .

5. Brewster angle microscope - Wikipedia

   en.wikipedia.org/wiki/Brewster_angle_microscope

   A Brewster angle microscope (BAM) is a microscope for studying thin films on liquid surfaces, most typically Langmuir films. In a Brewster angle microscope, both the microscope and a polarized light source are aimed towards a liquid surface at that liquid's Brewster angle , in such a way for the microscope to catch an image of any light ...

6. Liquid crystal on silicon - Wikipedia

   en.wikipedia.org/wiki/Liquid_crystal_on_silicon

   A CdTe light-blocking layer prevents the low-intensity writing light from shining through the device; the photosensor and light-blocking layer together form a rectifying junction, producing a DC voltage bias across the liquid crystal layer, transferring the image to the reflecting side [2]: 5 by changing the rotation of polarization in the ...

7. Diffuser (optics) - Wikipedia

   en.wikipedia.org/wiki/Diffuser_(optics)

   In optics, a diffuser (also called a light diffuser or optical diffuser) is any material that diffuses or scatters light in some manner to transmit soft light.Diffused light can be easily obtained by reflecting light from a white surface, while more compact diffusers may use translucent material, including ground glass, teflon, opal glass, and greyed glass.
