Stone in the context of Leptosol

Sculpture is the branch of the visual arts that operates in three dimensions. Sculpture is the three-dimensional art work which is physically presented in the dimensions of height, width and depth. It is one of the plastic arts. Durable sculptural processes originally used carving (the removal of material) and modelling (the addition of material, as clay), in stone, metal, ceramics, wood and other materials but, since Modernism, there has been almost complete freedom of materials and process. A wide variety of materials may be worked by removal such as carving, assembled by welding or modelling, or moulded or cast.

Sculpture in stone survives far better than works of art in perishable materials, and often represents the majority of the surviving works (other than pottery) from ancient cultures, though conversely traditions of sculpture in wood may have vanished almost entirely. In addition, most ancient sculpture was painted, which has been lost.

Christian Jürgensen Thomsen (29 December 1788 – 21 May 1865) was a Danish antiquarian who developed early archaeological techniques and methods.

In 1816 he was appointed head of 'antiquarian' collections which later developed into the National Museum of Denmark in Copenhagen. While organizing and classifying the antiquities for exhibition, he decided to present them chronologically according to the three-age system. Other scholars had previously proposed that prehistory had advanced from an age of stone tools, to ages of tools made from bronze and iron, but these proposals were presented as systems of evolution, which did not allow dating of artifacts. Thomsen refined the three-age system as a chronological system by seeing which artifacts occurred with which other artifacts in closed finds. In this way, he was the first to establish an evidence-based division of prehistory into discrete periods. This achievement led to his being credited as the originator of the three-age system of European antiquity.

Cement render or cement plaster is the application of a mortar mix of sand and cement, (optionally lime) and water to brick, concrete, stone, or mud brick. It is often textured, colored, or painted after application. It is generally used on exterior walls but can be used to feature an interior wall. Depending on the 'look' required, rendering can be fine or coarse, textured or smooth, natural or colored, pigmented or painted.

The cement rendering of brick, concrete and mud houses has been used for centuries to improve the appearance (and sometimes weather resistance) of exterior walls. It can be seen in different forms all over southern Europe. Different countries have their own styles and traditional colors. In the United Kingdom, cement is optional. In other countries, lime is optional. The cement in render hydrates the same way it does in concrete.

Beam bridges are the simplest structural forms for bridge spans supported by an abutment or pier at each end. No moments are transferred throughout the support, hence their structural type is known as simply supported.

The simplest beam bridge could be a log (see log bridge), a wood plank, or a stone slab (see clapper bridge) laid across a stream. Bridges designed for modern infrastructure will usually be constructed of steel or reinforced concrete, or a combination of both. The concrete elements may be reinforced or prestressed. Such modern bridges include girder, plate girder, and box girder bridges, all types of beam bridges.

Viking art, also known commonly as Norse art, is a term widely accepted for the art of Scandinavian Norsemen and Viking settlements further afield—particularly in the British Isles and Iceland—during the Viking Age of the 8th-11th centuries. Viking art has many design elements in common with Celtic, Germanic, the later Romanesque and Eastern European art, sharing many influences with each of these traditions.

Generally speaking, the current knowledge of Viking art relies heavily upon more durable objects of metal and stone; wood, bone, ivory and textiles are more rarely preserved. The artistic record, therefore, as it has survived to the present day, remains significantly incomplete. Ongoing archaeological excavation and opportunistic finds, of course, may improve this situation in the future, as indeed they have in the recent past.

Den, also known as Hor-Den, Dewen, and Udimu, was the Horus name of a pharaoh of the Early Dynastic Period who ruled during the First Dynasty of Egypt. He is the best archaeologically-attested ruler of this period, credited with bringing prosperity to his realm.

Den was attributed the title "King of Upper and Lower Egypt" and wore the double crown (red and white). Notably, the floor of his tomb at Umm El Qa'ab, near Abydos, was constructed using red and black granite, making it the earliest known use of this hard stone as a building material in Egypt with a flight of stairs leading to it. During his long reign, he established many of the customs of court ritual and royalty drawn on by later rulers and was held in high regard by his immediate successors.

Hardscape is hard landscape materials in the built environment structures that are incorporated into a landscape. This can include paved areas, driveways, retaining walls, sleeper walls, stairs, walkways, and any other landscaping made up of hard wearing materials such as wood, stone, and concrete, as opposed to softscape, the horticultural elements of a landscape.

Hard landscaping involves projects that cover the entirety of the yard and that are necessary before soft landscaping features come into play. Hard landscaping alters the foundation of the yard, the "bricks and mortar" so to speak; only when this is completed can the landscaper begin to focus on the softscape features of the yard, such as lawn, floral plantings, trees and shrubs. One key feature of hard landscaping has to do with the absorption of water – something that is of great importance given the climate. Hard landscaping ensures that worrying about water after heavy rain or snowfall is not an issue. The right water absorption and irrigation system installed through hard landscaping, coupled with hard materials that safely move water away from the property can ensure that soil movement is never a problem and that the yard stays a drier, enjoyable living space, rather than a wet and muddy bog. There are soft landscaping options that can help to achieve this, but the bulk of this is achieved through hard landscaping.

A cup is a small container used to hold liquids for drinking, typically with a flattened hemispherical shape and an open "mouth", and often with a capacity of about 6–16 US fluid ounces (177–473 ml). Cups may be made of pottery (including porcelain), glass, metal, wood, stone, polystyrene, plastic, lacquerware, or other materials. Normally, a cup is brought in contact with the mouth for drinking, distinguishing it from other tableware and drinkware forms such as jugs; however, a straw and/or lid may also be used. They also often have handles, though many do not, including beakers which have no handle or stem, or small bowl shapes which are very common in Asia.

There are many specific terms for different types of cups in different cultures, many depending on the type of drink they are mostly used for, and the material they are made of; in particular, cups made of glass are mostly called a "glass" in contemporary English. Cups of different styles may be used for different types of liquids or other foodstuffs (e.g, teacups and measuring cups), in different situations (e.g, at water stations or in ceremonies and rituals), or for decoration.

A guitar pick is a plectrum used for guitars. Picks are generally made of one uniform material, such as some kind of plastic (nylon, Delrin, celluloid), rubber, felt, tortoiseshell, wood, metal, glass, tagua, or stone. They are often shaped in an acute isosceles triangle with the two equal corners rounded and the third corner less rounded. They are used to strum chords or to sound individual notes on a guitar.

Chinese characters, also known as Han characters, Chinese script or Hanzi, are logographs used to write the Chinese languages and other Far Eastern languages from regions historically influenced by Chinese culture such as Japanese, Korean and (pre-colonial) Vietnamese. Unlike letters in the alphabets of most languages, which only transcribe the phonetics (phonemes) of speech (i.e. are phonegraphs), Chinese characters generally represent morphemes, the basic units of meaning in a language, thus making them the linguistic equivalent of words rather than letters, while the majority of "words" in the Chinese lexicon are in fact compounds and phrasemes (short phrases). The pronunciation of Chinese characters is transcribed phonetically via separate (usually romanized) transliteration systems such as the Pinyin, Zhuyin, Jyutping, Wade–Giles or Yale system.

At the most basic level, Chinese characters are composed of strokes (the actual linguistic equivalent of letters), which are written in a fixed stroke order for each character. The strokes are then organized into radicals, which are the fundamental root components that represent either a semantic feature or a homophone (often based on the Middle Chinese pronunciations) of the character. Historically, methods of writing characters have included carving inscriptions on stone, animal bones (usually turtle shells) or bronze; drawing ink onto bamboo slips, fabric (typically silk) or paper; and printing with woodblocks or moveable type. Technologies invented since the 19th century to facilitate the use of characters include telegraph codes and typewriters, as well as input methods and text encodings on computers.

Urolite is a term composed of two Greek words, uro- meaning "urine" and lithos meaning "stone" and was first used to describe the fossil of a nonliquid urinary secretions produced by some groups of reptiles, in relation to coprolites. The first evidence of recorded liquid waste elimination attributed to a dinosaur was presented to the public in 2002, but no scientific paper had reported fossil evidence of liquid waste of tetrapods elimination to assume that dinosaurs urinated.

In 2004, a paper by paleontologist Marcelo Adorna Fernandes brought a study of trace fossils that had been preserved in three aeolian flagstones.These trace fossils show a pattern that could be formed by an abundant falling stream of fluid and that is different from the structures described before in other occurrences in the paleontological record. The aspect of these urolites is very similar to soil deformation caused by modern ostrich urination, and certain groups of dinosaurs could have a similar urinary physiology. These urolites are the first evidence of liquid waste attributed to dinosaurs.

Patina (/pəˈtiːnə/ pə-TEE-nə or /ˈpætɪnə/ PAT-ih-nə) is a thin layer that variously forms on the surface of copper, brass, bronze, and similar metals and metal alloys (tarnish produced by oxidation or other chemical processes), or certain stones and wooden furniture (sheen produced by age, wear, and polishing), or any similar acquired change of a surface through age and exposure.

Additionally, the term is used to describe the aging of high-quality leather. The patinas on leather goods are unique to the type of leather, frequency of use, and exposure.

The motion of an object moving in a curved path is called curvilinear motion.Example: A stone thrown into the air at an angle.

Curvilinear motion describes the motion of a moving particle that conforms to a known or fixed curve. The study of such motion involves the use of two co-ordinate systems, the first being planar motion and the latter being cylindrical motion.

Lithotomy from Greek for "lithos" (stone) and "tomos" (cut), is a surgical method for removal of calculi, stones formed inside certain organs, such as the urinary tract (kidney stones), bladder (bladder stones), and gallbladder (gallstones), that cannot exit naturally through the urinary system or biliary tract. The procedure is usually performed by means of a surgical incision (therefore invasive). Lithotomy differs from lithotripsy, where the stones are crushed either by a minimally invasive probe inserted through the exit canal, or by an acoustic pulse (extracorporeal shock wave lithotripsy), which is a non-invasive procedure. Because of these less invasive procedures, the use of lithotomy has decreased significantly in the modern era.
