dramatic dialogue between a vase of flowers and a bottle of acid


Drama is the specific mode of fiction represented in performance. Considered as a genre of poetry in general, the dramatic mode has been contrasted with the epic and the lyrical modes ever since Aristotle's Poetics (c. 335 BC)—the earliest work of dramatic theory.
The term "drama" comes from a Greek word meaning "action" (Classical Greek: δρᾶμα, drama), which is derived from "I do" (Classical Greek: δράω, drao). The two masks associated with drama represent the traditional generic division between comedy and tragedy. They are symbols of the ancient Greek Muses, Thalia, and Melpomene. Thalia was the Muse of comedy (the laughing face), while Melpomene was the Muse of tragedy (the weeping face).
In English (as was the analogous case in many other European languages), the word "play" or "game" (translating the Anglo-Saxon plèga or Latin ludus) was the standard term used to describe drama until William Shakespeare's time—just as its creator was a "play-maker" rather than a "dramatist" and the building was a "play-house" rather than a "theatre". The use of "drama" in a more narrow sense to designate a specific type of play dates from the modern era. "Drama" in this sense refers to a play that isneither a comedy nor a tragedy—for example, Zola's Thérèse Raquin (1873) or Chekhov's Ivanov (1887). It is this narrower sense that the film and television industries, along with film studies, adopted to describe "drama" as a genre within their respective media. "Radio drama" has been used in both senses—originally transmitted in a live performance, it has also been used to describe the more high-brow and serious end of the dramatic output of radio.
The enactment of drama in theatre, performed by actors on a stage before an audience, presupposes collaborative modes of production and a collective form of reception. The structure of dramatic texts, unlike other forms of literature, is directly influenced by this collaborative production and collective reception.The early modern tragedy Hamlet (1601) by Shakespeare and the classical Athenian tragedy Oedipus Rex (c. 429 BC) by Sophocles are among the masterpieces of the art of drama. A modern example is Long Day's Journey into Night by Eugene O’Neill (1956).
Drama is often combined with music and dance: the drama in opera is generally sung throughout; musicals generally include both spoken dialogue and songs; and some forms of drama have incidental musicor musical accompaniment underscoring the dialogue (melodrama and Japanese Nō, for example). Closet drama describes a form that is intended to be read, rather than performed. In improvisation, the drama does not pre-exist the moment of performance; performers devise a dramatic script spontaneously before an audience.


(sometimes spelled dialog in American English is a written or spoken conversational exchange between two or more people, and a literary and theatrical form that depicts such an exchange. As anarrative, philosophical or didactic device, it is chiefly associated in the West with the Socratic dialogue as developed by Plato, but antecedents are also found in other traditions including Indian literature.
In the 20th century, philosophical treatments of dialogue emerged from thinkers including Mikhail Bakhtin, Paulo Freire, Martin Buber, and David Bohm. Although diverging in many details, these thinkers have articulated a holistic concept of dialogue as a multi-dimensional, dynamic and context-dependent process of creating meaning. Educators such as Freire and Ramón Flecha have also developed a body of theory and techniques for using egalitarian dialogue as a pedagogical tool.


(/ˈvɑːz/, /ˈveɪs/, or /ˈveɪz/) is an open container. It can be made from a number of materials, such as ceramics , glass, non-rusting metals, such as aluminum, brass, bronze or stainless steel. Even woodhas been used to make vases, either by using tree species that naturally resist rot, such as teak, or by applying a protective coating to conventional wood. Vases are often decorated, and they are often used to hold cut flowers.
Vases generally have a similar shape. The foot or the base may be bulbous, flat, carinate,[1] or another shape. The body forms the main portion of the piece. Some vases have a shoulder, where the body curves inward, a neck, which gives height, and a lip, where the vase flares back out at the top. Some vases are also given handles.
Various styles and types of vases have been developed around the world in different time periods, such as Chinese ceramics and Native American pottery. In the pottery of ancient Greece "vase-painting" is the traditional term covering the famous fine painted pottery, often with many figures in scenes from Greek mythology. Such pieces may be referred to as vases regardless of their shape; most were in fact used for holding or serving liquids, and many would more naturally be called cups, jugs and so on. In 2003, Grayson Perry won the Turner Prize for his ceramics, typically in vase form.


A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Magnoliophyta, also called angiosperms). The biological function of a flower is to effect reproduction, usually by providing a mechanism for the union of sperm with eggs. Flowers may facilitate outcrossing (fusion of sperm and eggs from different individuals in a population) or allow selfing (fusion of sperm and egg from the same flower). Some flowers produce diaspores without fertilization (parthenocarpy). Flowers contain sporangia and are the site wheregametophytes develop. Many flowers have evolved to be attractive to animals, so as to cause them to be vectors for the transfer of pollen. After fertilization, the ovary of the flower develops into fruit containing seeds.
In addition to facilitating the reproduction of flowering plants, flowers have long been admired and used by humans to bring beauty to their environment, and also as objects of romance, ritual, religion, medicine and as a source of food.


is a rigid container with a neck that is narrower than the body and a mouth. By contrast, a jar has a relatively large mouth or opening which may be as wide as the overall container. Bottles are often made of glass, clay, plastic, aluminium or other impervious materials, and typically used to store liquids such as water, milk, soft drinks, beer, wine,cooking oil, medicine, shampoo, ink, and chemicals. A device applied in the bottling line to seal the mouth of a bottle is termed an external bottle cap, closure, or internal stopper. A bottle can also be sealed by a conductive "innerseal" by using induction sealing.
The bottle has developed over millennia of use, with some of the earliest examples appearing in China, Phoenicia, Rome and Crete. Bottles are often recycled according to the SPIrecycling code for the material.


is a molecule or ion capable of donating a hydron (proton or hydrogen ion H+), or, alternatively, capable of forming a covalent bond with an electron pair (a Lewis acid).
The first category of acids is the proton donors or Brønsted acids. In the special case of aqueous solutions, proton donors form the hydronium ion H3O+ and are known as Arrhenius acids. Brønsted and Lowry generalized the Arrhenius theory to include non-aqueous solvents. A Brønsted or Arrhenius acid usually contains a hydrogen atom bonded to a chemical structure that is still energetically favorable after loss of H+.
Aqueous Arrhenius acids have characteristic properties which provide a practical description of an acid. Acids form aqueous solutions with a sour taste, can turn bluelitmus red, and react with bases and certain metals (like calcium) to form salts. The word acid is derived from the Latin acidus/acēre meaning sour. An aqueous solution of an acid has a pH less than 7 and is colloquially also referred to as 'acid' (as in 'dissolved in acid'), while the strict definition refers only to the solute.[1] A lower pH means a higher acidity, and thus a higher concentration of positive hydrogen ions in the solution. Chemicals or substances having the property of an acid are said to be acidic.
Common aqueous acids include hydrochloric acid (a solution of hydrogen chloride which is found in gastric acid in the stomach and activates digestive enzymes), acetic acid (vinegar is a dilute aqueous solution of this liquid), sulfuric acid (used in car batteries), and citric acid (found in citrus fruits). As these examples show, acids (in the colloquial sense) can be solutions or pure substances, and can be derived from acids (in the strict sense) that are solids, liquids, or gases. Strong acids and some concentrated weak acids are corrosive, but there are exceptions such as carboranes and boric acid.
The second category of acids are Lewis acids, which form a covalent bond with an electron pair. An example is boron trifluoride (BF3), whose boron atom has a vacant orbital which can form a covalent bond by sharing a lone pair of electrons on an atom in a base, for example the nitrogen atom in ammonia (NH3). Lewisconsidered this as a generalization of the Brønsted definition, so that an acid is a chemical species that accepts electron pairs either directly or by releasing protons (H+) into the solution, which then accept electron pairs. However, hydrogen chloride, acetic acid, and most other Brønsted-Lowry acids cannot form a covalent bond with an electron pair and are therefore not Lewis acids. Conversely, many Lewis acids are not Arrhenius or Brønsted-Lowry acids. In modern terminology, an acidis implicitly a Brønsted acid and not a Lewis acid, since chemists almost always refer to a Lewis acid explicitly as a Lewis acid.
