Referring to handedness, such as the helix handedness of screw threads or the mirror-image handedness of a symmetrical pair of parts. LM or L/M: list of materials: Also called a bill of materials (BoM, BOM). Overlaps a lot in concept with a parts list (PL or P/L). There is no consistently enforced distinction between an L/M, a BoM, or a P/L. LMC
A mirror image (in a plane mirror) is a reflected duplication of an object that appears almost identical, but is reversed in the direction perpendicular to the mirror surface. As an optical effect , it results from specular reflection off from surfaces of lustrous materials, especially a mirror or water .
A drawing of a butterfly with bilateral symmetry, with left and right sides as mirror images of each other.. In geometry, an object has symmetry if there is an operation or transformation (such as translation, scaling, rotation or reflection) that maps the figure/object onto itself (i.e., the object has an invariance under the transform).

Arabic-language "Objects in mirror are closer than they appear" warning The phrase " objects in (the) mirror are closer than they appear " is a safety warning that is required [ a ] to be engraved on passenger side mirrors of motor vehicles in many places such as the United States , Canada , Nepal , India , and South Korea .
In 1997 the geometry of the mirror's surface was adapted to create spherically curved glass with the goals of eliminating blind spots and offering an expanded field of view. [15] As of 2016 Gentex introduced the Gentex Full Display Mirror, which provides a video display with a panoramic view of what is behind the vehicle. [16]
Zhu leads a mirror-image biology lab at Westlake University in China. He was not involved in the Science paper. Adamala estimates that the world's first mirror bacteria is still about a decade away.
An autocollimator works by projecting an image onto a target mirror and measuring the deflection of the returned image against a scale, either visually or by means of an electronic detector. A visual autocollimator can measure angles as small as 1 arcsecond (4.85 microradians), while an electronic autocollimator can have up to 100 times more ...
