![]() Brewster believed it would at the same time become a popular instrument "for the purposes of rational amusement". Artists could accurately delineate the produced figures of the kaleidoscope by means of the solar microscope (a type of camera obscura device), magic lantern or camera lucida. ![]() īrewster thought his instrument to be of great value in "all the ornamental arts" as a device that creates an "infinity of patterns". The last step, regarded as most important by Brewster, was to place the reflecting panes in a draw tube with a concave lens to distinctly introduce surrounding objects into the reflected pattern. A version followed in which some of the objects and pieces of glass could move when the tube was rotated. An early version had pieces of colored glass and other irregular objects fixed permanently and was admired by some Members of the Royal Society of Edinburgh, including Sir George Mackenzie who predicted its popularity. This triggered more experiments to find the conditions for the most beautiful and symmetrically perfect conditions. A while later he was impressed by the multiplied reflection of a bit of cement that was pressed through at the end of a triangular glass trough, which appeared more regular and almost perfectly symmetrical in comparison to the reflected objects that had been situated further away from the reflecting plates in earlier experiments. He forgot about it, but noticed a more impressive version of the effect during further experiments in February 1815. In 1814, Sir David Brewster conducted experiments on light polarization by successive reflections between plates of glass and first noted "the circular arrangement of the images of a candle round a center, and the multiplication of the sectors formed by the extremities of the plates of glass". Rotation of the cell causes motion of the materials, resulting in an ever-changing view being presented.Ĭoined by its Scottish inventor David Brewster, "kaleidoscope" is derived from the Ancient Greek word καλός ( kalos), "beautiful, beauty", εἶδος ( eidos), "that which is seen: form, shape" and σκοπέω ( skopeō), "to look to, to examine", hence "observation of beautiful forms." It was first published in the patent that was granted on July 10, 1817. These reflectors are usually enclosed in a tube, often containing on one end a cell with loose, colored pieces of glass or other transparent (and/or opaque) materials to be reflected into the viewed pattern. Also note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.For other uses, see Kaleidoscope (disambiguation).Ī kaleidoscope ( / k ə ˈ l aɪ d ə s k oʊ p/) is an optical instrument with two or more reflecting surfaces (or mirrors) tilted to each other at an angle, so that one or more (parts of) objects on one end of these mirrors are shown as a regular symmetrical pattern when viewed from the other end, due to repeated reflection. ![]() Note that when grown in a container, it may not perform exactly as indicated on the tag - this is to be expected. It can be used either as 'filler' or as a 'thriller' in the 'spiller-thriller-filler' container combination, depending on the height and form of the other plants used in the container planting. This particular variety is an interspecific hybrid.Kaleidoscope Abelia makes a fine choice for the outdoor landscape, but it is also well-suited for use in outdoor pots and containers. It is somewhat tolerant of urban pollution. It is not particular as to soil type or pH. It does best in average to evenly moist conditions, but will not tolerate standing water. It grows at a slow rate, and under ideal conditions can be expected to live for approximately 30 years.This shrub does best in full sun to partial shade. It tends to fill out right to the ground and therefore doesn't necessarily require facer plants in front. Kaleidoscope Abelia will grow to be about 30 inches tall at maturity, with a spread of 4 feet.
