At Roseland, an older lady, May ( Wright ), with a light step, looks for the memory of her husband in the ballroom's mirrors.

In many ways, this preface by von Kupffer remains relevant today, as the argument between von Kupffer and Hirschfeld mirrors later similar arguments, e. g. between Adolf Brand and Hirschfeld, or since the 1960s, between advocates of pederastic relationships and the mainstream gay liberation movement.

Most mirrors are designed for visible light ; however, mirrors designed for other types of waves or other wavelengths of electromagnetic radiation are also used, especially in non-optical instruments.

: Convex mirrors provide a wider field of view than flat mirrors, and are often used on vehicles, especially large trucks, to minimize blind spots.

Particularly strong in this tradition were figurative sculpture in terracotta ( particularly life-size on sarcophagi or temples ) and cast bronze, wall-painting and metalworking ( especially engraved bronze mirrors ).

Although it was written as if it were a traditional work in the mirrors for princes style, it is generally agreed that it was especially innovative.

The focus on the " thing " as " thing " ( an attempt at isolating a single image to reveal its essence ) also mirrors contemporary developments in avant-garde art, especially Cubism.

Most of his work is in wood, especially decorative Baroque garlands made up of still-life elements at about life size, made to frame mirrors and decorate the walls of churches and palaces, but he also produced furniture and small relief plaques with figurative scenes.

This was a subject Shelley wrote a great deal about, especially around 1819, with this strongest version of it articulated the last famous lines of his " Defence of Poetry ": " Poets are the hierophants of an unapprehended inspiration ; the mirrors of the gigantic shadows which futurity casts upon the present ; the words which express what they understand not ; the trumpets which sing to battle, and feel not what they inspire ; the influence which is moved not, but moves.

His name is best known for the improvements he effected in the mirrors of reflecting telescopes and especially in the construction of the microscope.

In some ways this relationship mirrors the " Don't like him but need his help " mutual feelings that Jon Pertwee's incarnation of the Doctor in Doctor Who has with Brigadier Lethbridge-Stewart — Marker is very suspicious of authority figures, especially policemen, and Firbank initially at least considers enquiry agents to be a lower form of life.

In MOSFET technology especially, cascoding can be used in current mirrors to increase the output impedance of the output current source.

Some popular mirrors, especially the convex style, and some large dressing glasses of the 19th century were known as " girandoles " because of the lighting devices mounted to their sides.

The arrangement mirrors the one designed by Bernini for the Tomb of Urban VIII ( 1628 – 47 ), with a central hieratic sculpture of the pope seated in full regalia and offering a hand of blessing, while at his feet, two allegorical female figures flank his sarcophagus.

In the third book, Dürer gives principles by which the proportions of the figures can be modified, including the mathematical simulation of convex and concave mirrors ; here Dürer also deals with human physiognomy.

Burning mirrors achieve a similar effect by using reflecting surfaces to focus the light.

Archimedes, the renowned mathematician, was said to have used a burning glass ( or more likely a large number of angled hexagonal mirrors ) as a weapon in 212 BC, when Syracuse was besieged by Marcus Claudius Marcellus.

The pop science TV program MythBusters attempted to model Archimedes ' feat by using mirrors to ignite a small wooden boat covered with tar, with only partial success — they found it too difficult to focus light from their hand-held mirrors onto a point small enough to ignite the boat.

" However, held the Cadillac court, " one who manufactures articles dangerous only if defectively made, or installed, e. g., tables, chairs, pictures or mirrors hung on the walls, carriages, automobiles, and so on, is not liable to third parties for injuries caused by them, except in case of willful injury or fraud ,"

Sir Charles Wheatstone discovered its principle and applied it as early as 1838 to the construction of a cumbersome but effective instrument, in which the binocular pictures were made to combine by means of mirrors.

Geometric optics uses Euclidean geometry to analyze the focusing of light by lenses and mirrors.

" After a spectacular fight in a room full of mirrors, Han is defeated by Lee and impaled on his own spear.

In it, Kepler described the inverse-square law governing the intensity of light, reflection by flat and curved mirrors, and principles of pinhole cameras, as well as the astronomical implications of optics such as parallax and the apparent sizes of heavenly bodies.

Around 1439, Gutenberg was involved in a financial misadventure making polished metal mirrors ( which were believed to capture holy light from religious relics ) for sale to pilgrims to Aachen: in 1439 the city was planning to exhibit its collection of relics from Emperor Charlemagne but the event was delayed by one year due to a severe flood and the capital already spent could not be repaid.

Light from the medium, produced by spontaneous emission, is reflected by the mirrors back into the medium, where it may be amplified by stimulated emission.

* Multi-conjugate Adaptive optics Demonstrator, astronomical method of using multiple guide stars and deformable mirrors to sense and correct for the distortions produced by turbulence in Earth's atmosphere

The first mirrors used by people were most likely pools of dark, still water, or water collected in a primitive vessel of some sort.

In China, bronze mirrors were manufactured from around 2000 BC, some of the earliest bronze and copper examples being produced by the Qijia culture.

Metal-coated glass mirrors are said to have been invented in Sidon ( modern-day Lebanon ) in the first century AD, and glass mirrors backed with gold leaf are mentioned by the Roman author Pliny in his Natural History, written in about 77 AD.

The Romans also developed a technique for creating crude mirrors by coating blown glass with molten lead.

Parabolic mirrors were described and studied in classical antiquity by the mathematician Diocles in his work On Burning Mirrors.

Parabolic mirrors were also described by the physicist Ibn Sahl in the 10th century, and Ibn al-Haytham discussed concave and convex mirrors in both cylindrical and spherical geometries, carried out a number of experiments with mirrors, and solved the problem of finding the point on a convex mirror at which a ray coming from one point is reflected to another point.

Self-similarity itself is not necessarily counter-intuitive ( e. g., people have pondered self-similarity informally such as in the infinite regress in parallel mirrors or the homunculus, the little man inside the head of the little man inside the head ...).

This type of glass is widely used for decorative purposes ( e. g., on mirrors, table tops, doors, windows, kitchen chop boards, etc.

It was often expressed as " ontogeny recapitulates phylogeny ", i. e. the development of an organism successively mirrors the adult stages of successive ancestors of the species it belongs to.

Moreover, oil lanterns cannot be seen very far over water at night, unless they are large, fitted with mirrors or lenses, and mounted at a great height ( i. e., in a lighthouse ).

This would be easier with some confinement schemes ( e. g. magnetic mirrors ) than with others ( e. g. tokamaks ).

For a thick lens ( one which has a non-negligible thickness ), or an imaging system consisting of several lenses and / or mirrors ( e. g., a photographic lens or a telescope ), the focal length is often called the effective focal length ( EFL ), to distinguish it from other commonly-used parameters:

d, d ' and e are mirrors.

:( c ) transmission media, e. g. electronic components, antennas, electromagnetic waveguides, flat mirrors, mirrors with curved surfaces convex lenses, concave lenses ; resistors, inductors, capacitors, switches ; wires, electric and optical cables, transmission lines, integrated circuits etc ;

A module defines its source code to be in a package ( much like a Java package ), the Perl mechanism for defining namespaces, e. g. CGI or Net :: FTP or XML :: Parser ; the file structure mirrors the namespace structure ( e. g. the source code for Net :: FTP is in Net / FTP. pm ).

If the optical cavity is not empty ( e. g., a laser cavity which contains the gain medium ), the value of L used is not the physical mirror separation, but the optical path length between the mirrors.

Recent geoengineering proposals have principally been methods to tackle human-induced climate change by either removing carbon dioxide from the atmosphere ( e. g. using ocean iron fertilization ) or by managing solar radiation ( e. g. by using mirrors in space ) in order to negate the net warming effect of climate change.

The low voltage output winding mirrors the sawtooth of the primary current and, e. g. for television purposes, has fewer turns than the primary thus providing a higher current.

Usually, these lines do not operate unless the gain of the strongest transition is suppressed, e. g., by use of wavelength-selective dielectric mirrors.

The parts typically dismantled from automobiles are any small and easily removable items, such as the light assemblies ( commonly known as just " lights ", e. g. headlights, blinkers, taillights ), seats, parts of the exhaust system, mirrors, hubcaps etc.

In many experiments with atoms, the roles of matter and light are reversed compared to the laser based interferometers, i. e. the beam splitter and mirrors are lasers while the source instead emits matter waves ( the atoms ).

Phantom Works ' organization mirrors that of Boeing's Defense business units, with ' Advanced ' versions of each unit ( e. g. Advanced Boeing Military Aircraft ).

The final production model came with several variations from the pre-production show models e. g. the vents on the wings are filled in, different wing mirrors, location of the fuel filler and bonnet hinges.
