Botany

Botany, also called plant science(s) or plant biology, is the science of plant life and a branch of biology. A botanist or plant scientist is a scientist who specializes in this field of study. The term "botany" comes from the Ancient Greek word βοτάνη (botanē) meaning "pasture", "grass", or "fodder"; βοτάνη is in turn derived from βόσκειν (boskein), "to feed" or "to graze". Traditionally, botany has also included the study of fungi and algae by mycologists and phycologists respectively, with the study of these three groups of organisms remaining within the sphere of interest of the International Botanical Congress. Nowadays, botanists study approximately 400,000 species of living organisms of which some 260,000 species are vascular plants and about 248,000 are flowering plants.

Botany originated in prehistory as herbalism with the efforts of early humans to identify – and later cultivate – edible, medicinal and poisonous plants, making it one of the oldest branches of science. Medieval physic gardens, often attached to monasteries, contained plants of medical importance. They were forerunners of the first botanical gardens attached to universities, founded from the 1540s onwards. One of the earliest was the Padua botanical garden. These gardens facilitated the academic study of plants. Efforts to catalogue and describe their collections were the beginnings of plant taxonomy, and led in 1753 to the binomial system of Carl Linnaeus that remains in use to this day.

Scientist

A scientist is a person engaging in a systematic activity to acquire knowledge. In a more restricted sense, a scientist may refer to an individual who uses the scientific method. The person may be an expert in one or more areas of science. This article focuses on the more restricted use of the word. Scientists perform research toward a more comprehensive understanding of nature, including physical, mathematical and social realms.

Philosophy is a distinct activity that is not generally considered science. Philosophers aim to provide a comprehensive understanding of intangible aspects of reality and experience that cannot be physically measured.

Scientists are also distinct from engineers, those who design, build, and maintain devices for particular situations; however, no engineer attains that title without significant study of science and the scientific method. When science is done with a goal toward practical utility, it is called applied science. An applied scientist may not be designing something in particular, but rather is conducting research with the aim of developing new technologies and practical methods. When science is done with an inclusion of intangible aspects of reality it is called natural philosophy.

Scientist (musician)

Hopeton Brown (born 18 April 1960), better known as Scientist and sometimes known as Overton Brown, was a protégé of King Tubby (Osbourne Ruddock), one of the originators of dub music.

Biography

Brown was introduced to electronics by his father, who worked as a television and radio repair technician. He began building his own amplifiers and would buy transformers from Tubby's Dromilly Road studio, and while there would keep asking Tubby to give him a chance at mixing. He was taken on at Tubby's as an assistant, performing tasks such as winding transformer coils, and began working as a mixer in the mid-1970s, initially creating dubs of reworked Studio One riddims for Don Mais' Roots Tradition label, given his chance when Prince Jammy cut short a mixing session for Mais because he was too tired to continue. His name originated from a joke between Tubby and Bunny Lee. Having noticed Brown's forward thinking ideas and technical aspirations, Tubby remarked "Damn, this little boy must be a scientist."

Plant

Plants, also called green plants, are multicellular eukaryotes of the kingdom Plantae. They form an unranked clade Viridiplantae (Latin for green plants) that includes the flowering plants, conifers and other gymnosperms, ferns, clubmosses, hornworts, liverworts, mosses and the green algae. Green plants excludes the red and brown algae, the fungi, archaea, bacteria and animals.

Green plants have cell walls with cellulose and obtain most of their energy from sunlight via photosynthesis by primary chloroplasts, derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic and have lost the ability to produce normal amounts of chlorophyll or to photosynthesize. Plants are also characterized by sexual reproduction, modular and indeterminate growth, and an alternation of generations, although asexual reproduction is also common.

Precise numbers are difficult to determine, but as of 2010, there are thought to be 300–315 thousand species of plants, of which the great majority, some 260–290 thousand, are seed plants (see the table below). Green plants provide most of the world's molecular oxygen and are the basis of most of the earth's ecologies, especially on land. Plants that produce grains, fruits and vegetables form mankind's basic foodstuffs, and have been domesticated for millennia. Plants are used as ornaments and, until recently and in great variety, they have served as the source of most medicines and drugs. The scientific study of plants is known as botany, a branch of biology.

Plantà

The plantá (which comes from the verb to plant; in Valencian, plantà) is the act of erecting a Falla or bonfire monument, in the Fallas or the Bonfires of Saint John, festivals held respectively in March and June in different localities of the Community of Valencia (Spain).The plantà is currently considered the exact moment when the falla or bonfire is completely finished and ready to be visited, with all its “ninots” (human figures made of combustible materials, such as cardboard or wood, which has a critical or mocking nature), posters and a variety of features (lights, matted grass, interpretive signs...).

In the Fallas of Valencia, the plantá takes place on March 15, when all the Falla monuments must be positioned correctly. The reason is that the jury appointed by the Central Fallera committee has to go to the next day to assess the falla. Formerly, the plantà began and ended the same day but, due to the complexity of the monuments and the fact that the makers of Fallas are responsible for several Fallas monuments at the same time, it usually begins a few days before. The burning of the Falla or cremá is carried out four days later, on the night of March 19.
