There are many branches of chemistry or chemistry disciplines. The five main branches are considered to be organic chemistry, inorganic chemistry, analytical chemistry, physical chemistry, and biochemistry. Overview of the 5 Branches of Chemistry Organic Chemistry: The study of carbon and its compounds; the study of the chemistry of life Inorganic Chemistry: The study of compounds not covered by organic chemistry; the study of inorganic compounds, or compounds that don't contain a C-H bond (many inorganic compounds contain metals) Analytical Chemistry: The study of the chemistry of matter and the development of tools to measure properties of matter Physical Chemistry: The branch of chemistry that applies physics to the study of chemistry, which commonly includes the applications of thermodynamics and quantum mechanics to chemistry Biochemistry: The study of chemical processes that occur inside of living organisms There are other ways chemistry can be divided into categories.
Constantin Brancusi (1876-1957) was a Romanian sculptor who became a French citizen shortly before his death. He was one of the most important and influential sculptors of the 20th century. His use of abstract forms to represent natural concepts led the way toward minimalist art in the 1960s and beyond.
Mario Vargas Llosa is a Peruvian writer and Nobel Prize winner who is considered to be part of the "Latin American Boom" of the 1960s and 70s, a group of influential writers including Gabriel García Márquez and Carlos Fuentes. While his early novels were known for their critique of authoritarianism and capitalism, Vargas Llosa's political ideology shifted in the 1970s and he began to see socialist regimes, particularly Fidel Castro's Cuba, as repressive for writers and artists.
Attachment describes the deep, long-term bonds that form between two people. John Bowlby originated attachment theory to explain how these bonds form between an infant and a caregiver, and Mary Ainsworth later expanded on his ideas. Since it was initially introduced, attachment theory has become one of the most well-known and influential theories in the field of psychology.
At the end of a long, cold, nearly bug-free winter, it's always a thrill for the insect enthusiasts among us to spy a group of snow fleas hopping merrily in the melting snow. While few may be fans of the common flea, snow fleas aren't really fleas at all. Like spiders, scorpions, horseshoe crabs, and katydids, snow fleas are actually arthropods-specifically of the springtail variety.
The World Conservation Union ranks the gypsy moth, Lymantria dispar , on its list of "100 of the World's Most Invasive Alien Species." If you live in the northeastern U.S., you will heartily agree with that characterization of this tussock moth. Accidentally introduced to the U.S. in the late 1860s, the gypsy moth now consumes a million acres of forest each year, on average.
The study of anthropology is the study of human beings: their culture, their behavior, their beliefs, their ways of surviving. Here is a collection of other definitions of anthropology from anthropologists and other dedicated to defining and describing what Alexander Pope (1688 to 1744) called the "proper study of mankind.
Childe Hassam (1859-1935) was an American painter who played a crucial role in popularizing impressionism in the United States.

Such was the funeral that took place during this winter, with which the first year of the war came to an end. In the first days of summer the Lacedaemonians and their allies, with two-thirds of their forces as before, invaded Attica, under the command of Archidamus, son of Zeuxidamus, King of Lacedaemon, and sat down and laid waste the country.
Have you ever wondered why the formation of ionic compounds is exothermic? The quick answer is that the resulting ionic compound is more stable than the ions that formed it. The extra energy from the ions is released as heat when ionic bonds form. When more heat is released from a reaction than is needed for it to happen, the reaction is exothermic.
The star pattern astronomers know as Cygnus appears high in the sky beginning in July and is still visible late in the year. Its central area is cross-shaped, and that asterism within the constellation is called the Northern Cross. It is one of three constellations that lends a star to the asterism called the Summer Triangle, which is another stargazing feature that is high in the skies during the northern hemisphere summer.
President Ronald Reagan will forever be remembered fondly by Second Amendment supporters, many who are among the American conservatives who consider Reagan the epitome of modern conservatism. But words and actions of Reagan, the 40th President of the United States, left behind a mixed record on gun rights.
Several types of reactions occur in water. When water is the solvent for a reaction, the reaction is said to occur in aqueous solution, which is denoted by the abbreviation (aq) following the name of a chemical species in a reaction. Three important types of reactions in water are precipitation , acid-base , and oxidation-reduction reactions.
Best known for the lavish Hearst Castle, Julia Morgan also designed public venues for the YWCA as well as hundreds of homes in California. Morgan helped rebuild San Francisco after the earthquake and fires of 1906, except for the bell tower at Mills College, which she had already designed to survive the damage.
Shark scientists have questioned basking shark migration for decades since an article in 1954 proposed that basking sharks, which were hardly seen once cold weather hit, hibernated on the ocean bottom during the winter. A tagging study released in 2009 finally revealed that basking sharks head south in the winter, further than scientists ever dreamed.
Joseph McCarthy was a United States Senator from Wisconsin whose crusade against suspected communists created a political frenzy in the early 1950s. The actions of McCarthy dominated the news to such a degree that the word McCarthyism entered the language to describe the hurling of unfounded accusations.
Marsden Hartley (1877-1943) was an American modernist painter. His embrace of Germany during World War I and the regionalist subject matter of his late-career work caused contemporary critics to dismiss the value of much of his painting. Today, Hartley's importance in the development of modernism and expressionism in American art is recognized.

Many woodpeckers and sapsuckers are tree bark-feeding birds with unique clinging feet, long tongues, and specialized beaks. These beaks are designed to help with communicating the possession of territory to rivals and locating and accessing sap and insects. This is done mostly by rapid drumming and pecking noisily on tree trunks with their beaks.
No one likes writing a resume, but it's a critical part of the job search in all fields. In academics, the resume is called a curriculum vitae (or CV) and it is even less fun to write. Unlike a resume which presents your experience and skills within a 1-page format, the curriculum vitae has no page limit.
You may take it for granted that matter is made up of atoms, but what we consider common knowledge was unknown until relatively recently in human history. Most science historians credit John Dalton, a British physicist, chemist, and meteorologist, with the development of modern atomic theory. Early Theories While the ancient Greeks believed atoms made matter, they disagreed on what atoms were.
