Social science

Social science is a major category of academic disciplines, concerned with society and the relationships among individuals within a society. It in turn has many branches, each of which is considered a "social science". The main social sciences include economics, political science, human geography, demography and sociology. In a wider sense, social science also includes some fields in the humanities such as anthropology, archaeology, jurisprudence, psychology, history, and linguistics. The term is also sometimes used to refer specifically to the field of sociology, the original 'science of society', established in the 19th century.

Positivist social scientists use methods resembling those of the natural sciences as tools for understanding society, and so define science in its stricter modern sense. Interpretivist social scientists, by contrast, may use social critique or symbolic interpretation rather than constructing empirically falsifiable theories, and thus treat science in its broader sense. In modern academic practice, researchers are often eclectic, using multiple methodologies (for instance, by combining the quantitative and qualitative techniques). The term social research has also acquired a degree of autonomy as practitioners from various disciplines share in its aims and methods.

Solar System

The Solar System is the gravitationally bound system comprising the Sun and the objects that orbit it, either directly or indirectly. Of those objects that orbit the Sun directly, the largest eight are the planets, with the remainder being significantly smaller objects, such as dwarf planets and small Solar System bodies. Of the objects that orbit the Sun indirectly, the moons, two are larger than the smallest planet, Mercury.

The Solar System formed 4.6 billion years ago from the gravitational collapse of a giant interstellar molecular cloud. The vast majority of the system's mass is in the Sun, with most of the remaining mass contained in Jupiter. The four smaller inner planets, Mercury, Venus, Earth and Mars, are terrestrial planets, being primarily composed of rock and metal. The four outer planets are giant planets, being substantially more massive than the terrestrials. The two largest, Jupiter and Saturn, are gas giants, being composed mainly of hydrogen and helium; the two outermost planets, Uranus and Neptune, are ice giants, being composed mostly of substances with relatively high melting points compared with hydrogen and helium, called ices, such as water, ammonia and methane. All planets have almost circular orbits that lie within a nearly flat disc called the ecliptic.

Social

The term social refers to a characteristic of living organisms as applied to populations of humans and other animals. It always refers to the interaction of organisms with other organisms and to their collective co-existence, irrespective of whether they are aware of it or not, and irrespective of whether the interaction is voluntary or involuntary.

Etymology

The word "Social" derives from the Latin word socii ("allies"). It is particularly derived from the Italian Socii states, historical allies of the Roman Republic (although they rebelled against Rome in the Social War of 91-88 BC).

Definition

In the absence of agreement about its meaning, the term "social" is used in many different senses and regarded as a fuzzy concept, referring among other things to:

Attitudes, orientations, or behaviors which take the interests, intentions, or needs of other people into account (in contrast to anti-social behaviour) has played some role in defining the idea or the principle. For instance terms like social realism, social justice, social constructivism, social psychology, social anarchism and social capital imply that there is some social process involved or considered, a process that is not there in regular, "non-social" realism, justice, constructivism, psychology, anarchism, or capital.

Science

Science is a systematic enterprise that creates, builds and organizes knowledge in the form of testable explanations and predictions about the universe.

Contemporary science is typically subdivided into the natural sciences which study the material world, the social sciences which study people and societies, and the formal sciences like mathematics. The formal sciences are often excluded as they do not depend on empirical observations. Disciplines which use science like engineering and medicine may also be considered to be applied sciences.

During the middle ages in the Middle East, foundations for the scientific method were laid by Alhazen. From classical antiquity through the 19th century, science as a type of knowledge was more closely linked to philosophy than it is now and, in fact, in the West the term "natural philosophy" encompassed fields of study that are today associated with science, such as physics, astronomy and medicine.

In the 17th and 18th centuries scientists increasingly sought to formulate knowledge in terms of laws of nature. Over the course of the 19th century, the word "science" became increasingly associated with the scientific method itself, as a disciplined way to study the natural world. It was in the 19th century that scientific disciplines such as physics, chemistry, and biology reached their modern shapes. The same time period also included the origin of the terms "scientist" and "scientific community," the founding of scientific institutions, and increasing significance of the interactions with society and other aspects of culture.

Nicholas A. Christakis

Nicholas A. Christakis (born May 7, 1962) is an American sociologist and physician known for his research on social networks and on the socioeconomic and biosocial determinants of behavior, health, and longevity. He is the Sol Goldman Family Professor of Social and Natural Science at Yale University. He directs the Human Nature Lab, and he is the Co-Director of the Yale Institute for Network Science.

He was elected to the Institute of Medicine of the National Academy of Sciences in 2006, and he was named a Fellow at the American Association for the Advancement of Science in 2010.

In 2009, he was named to the Time 100, Time magazine's list of the 100 most influential people in the world. In 2009 and again in 2010, Christakis was named by Foreign Policy magazine to its list of top global thinkers.

Education

Christakis received a B.S. in biology from Yale University in 1984, where he won the Russell Henry Chittenden Prize. He received an M.D. from Harvard Medical School and an M.P.H. from the Harvard School of Public Health in 1989, winning the Bowdoin Prize on graduation.
