Paris
Paris () is the capital and most populous city of France, with an estimated population of 2,165,423 residents in 2019 in an area of more than 105 km² (41 sq mi), making it the 30th most densely populated city in the world in 2020. Since the 17th century, Paris has been one of the world's major centres of finance, diplomacy, commerce, fashion, gastronomy, and science. For its leading role in the arts and sciences, as well as its very early system of street lighting, in the 19th century it became known as "the City of Light". Like London, prior to the Second World War, it was also sometimes called the capital of the world. The City of Paris is the centre of the Île-de-France region, or Paris Region, with an estimated population of 12,262,544 in 2019, or about 19% of the population of France, making the region France's primate city. The Paris Region had a GDP of €739 billion ($743 billion) in 2019, which is the highest in Europe. According to the Economist Intelli ...

Primulaceae
The Primulaceae , commonly known as the primrose family (but not related to the Onagraceae, evening primrose family), are a family (biology), family of Herbaceous plant, herbaceous and woody flowering plants including some favourite garden plants and wildflowers. Most are Perennial plant, perennial though some species, such as Anagallis arvensis, scarlet pimpernel, are annual plant, annuals. Previously one of three families in the Order (biology), order Primulales, it underwent considerable genus, generic re-alignment once molecular phylogenetic methods were used for taxonomic classification. The order was then submerged in a much enlarged order Ericales and became a greatly enlarged Primulaceae ''sensu lato'' (''s.l''). In this new classification of the Angiosperm Phylogeny Group, each of the Prumulales families was reduced to the rank of subfamily of Primulaceae ''s.l.'' The original Primulaceae (Primulaceae ''sensu stricto'' or ''s.s.'') then became subfamily Primuloideae, and ...

19th-century French Botanists
The 19th (nineteenth) century began on 1 January 1801 ( MDCCCI), and ended on 31 December 1900 ( MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanding beyond its British homeland for the first time during this century, particularly remaking the economies and societies of the Low Countries, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under colonial rule. It was also marked by the collapse of the large S ...

Scientists From Paris
A scientist is a person who conducts scientific research to advance knowledge in an area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales (circa 624-545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. In modern times, many scientists have advanced degrees in an area of science and pursue careers in various sectors of the economy such as academia, industry, government, and nonprofit environments.''''

1780 Births
Year 178 ( CLXXVIII) was a common year starting on Wednesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Scipio and Rufus (or, less frequently, year 931 ''Ab urbe condita'').

Medical Dictionary
A medical dictionary is a lexicon for words used in medicine. The three major medical dictionaries in the United States are ''Stedman's'', ''Taber's'', and ''Dorland's''. Other significant medical dictionaries are distributed by Elsevier. Dictionaries often have multiple versions, with content adapted for different user groups. For example Stedman's Concise Medical Dictionary and Dorland's are for general use and allied health care, while the full text editions are reference works used by medical students, doctors, and health professionals. Medical dictionaries are commonly available in print, online, or as downloadable software packages for personal computers and smartphones. History The earliest known glossaries of medical terms were discovered on Egyptian papyrus authored around 1600 B.C. Other precursors to modern medical dictionaries include lists of terms compiled from the Hippocratic Corpus in the first century AD. The '' Synonyma Simonis Genuensis'' (the ''Synonyms ...

Ranunculaceae
Ranunculaceae (buttercup or crowfoot family; Latin "little frog", from "frog") is a family of over 2,000 known species of flowering plants in 43 genera, distributed worldwide. The largest genera are ''Ranunculus'' (600 species), ''Delphinium'' (365), ''Thalictrum'' (330), ''Clematis'' (325), and ''Aconitum'' (300). Description Ranunculaceae are mostly herbaceous annuals or perennials, but some are woody climbers (such as ''Clematis'') or shrubs (e.g. ''Xanthorhiza''). Most members of the family have bisexual flowers which can be showy or inconspicuous. Flowers are solitary, but are also found aggregated in cymes, panicles, or spikes. The flowers are usually radially symmetrical but are also found to be bilaterally symmetrical in the genera ''Aconitum'' and ''Delphinium''. The sepals, petals, stamens and carpels are all generally free (not fused), the outer flower segments typically number four or five. The outer stamens may be modified to produce only nectar, as in Aqui ...

Asteraceae
The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales. Commonly referred to as the aster, daisy, composite, or sunflower family, Compositae were first described in the year 1740. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of extant species in each family is unknown. Most species of Asteraceae are annual, biennial, or perennial herbaceous plants, but there are also shrubs, vines, and trees. The family has a widespread distribution, from subpolar to tropical regions in a wide variety of habitats. Most occur in hot desert and cold or hot semi-desert climates, and they are found on every continent but Antarctica. The primary common characteristic is the existence of sometimes hundreds of tiny individual florets which are held together by protective involucres in flower heads, or more technicall ...

Botanist
Botany, also called , plant biology or phytology, is the science of plant life and a branch of biology. A botanist, plant scientist or phytologist is a scientist who specialises in this field. The term "botany" comes from the Ancient Greek word (''botanē'') meaning "pasture", " herbs" "grass", or " fodder"; is in turn derived from (), "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 (in the strict sense) study approximately 410,000 species of land plants of which some 391,000 species are vascular plants (including approximately 369,000 species of flowering plants), and approximately 20,000 are bryophytes. Botany originated in prehistory as herbalism with the efforts of early humans to identify – and later cultivate – edible, med ...

Lasallia
''Lasallia'' is a genus of lichenized fungi in the family Umbilicariaceae. The genus name of ''Lasallia'' is in honour of Mr. Lasalle (around 1820), who was a French gardener and botanist, who worked in Fontainebleau. It was circumscribed by François Victor Mérat de Vaumartoise in Nouv. Fl. Paris ed.2, vol.1 on page 202 in 1821. The genus contains 12 species with a widespread, but predominantly temperate distribution. Phylogenetic analysis of internal transcribed spacer DNA has shown that the genus is monophyletic. High performance liquid chromatography analysis of eleven ''Lasallia'' species revealed a number of secondary metabolites in this genus, including gyrophoric acid, lecanoric acid Lecanoric acid is a chemical produced by several species of lichen.ubChem - Lecanoric acid"> Lecanoric acid is classified as a polyphenol and a didepside and it functions as an antioxidant. The acid is named after the lichen ''Lecanora''. The acid ..., umbilicaric acid, 7-chloroemo ...
