The Michelson–Morley experiment was used to disprove that light propagated through a luminiferous aether. This 19th century concept was then superseded by Albert Einstein's special theory of relativity.
The Michelson–Morley experiment was used to disprove that light propagated through a luminiferous aether. The Michelson–Morley experiment, one of the most important and famous experiments in the History of physics, was performed in 1887 by Albert Michelson and In the late 19th century " luminiferous aether " (or " ether " meaning light-bearing aether, was the term used to describe a medium for the propagation This 19th century concept was then superseded by Albert Einstein's special theory of relativity.

In science, the term natural science refers to a rational approach to the study of the universe, which is understood as obeying rules or law of natural origin. Science (from the Latin scientia, meaning " Knowledge " or "knowing" is the effort to discover, and increase human understanding In Epistemology and in its broadest sense rationalism is "any view appealing to Reason as a source of knowledge or justification" (Lacey 286 The Universe is defined as everything that Physically Exists: the entirety of Space and Time, all forms of Matter, Energy Nature, in the broadest sense is equivalent to the natural world, physical universe, material world or material universe. The term natural science is also used to distinguish those fields that use the scientific method to study nature from the social sciences, which use the scientific method to study human behavior and society; and from the formal sciences, such as mathematics and logic, which use a different (a priori) methodology. Scientific method refers to bodies of Techniques for investigating phenomena Nature, in the broadest sense is equivalent to the natural world, physical universe, material world or material universe. The social sciences comprise academic disciplines concerned with the study of the social life of human groups and individuals including Anthropology, Communication studies A formal science is a theoretical study that is concerned with theoretical Formal systems, for instance Logic, Mathematics, Systems theory and Mathematics is the body of Knowledge and Academic discipline that studies such concepts as Quantity, Structure, Space and Logic is the study of the principles of valid demonstration and Inference. "A priori" redirects here For other uses see A priori. Methodology (also called manner) is defined as "the analysis of the principles of methods rules and postulates employed by a discipline"

Overview

Natural sciences form the basis for the applied sciences. For the song by 311, see Grassroots. Applied science is the application of knowledge from one or more natural scientific Together, the natural and applied sciences are distinguished from the social sciences on the one hand, and the liberal arts (humanities, theology, etc. The social sciences comprise academic disciplines concerned with the study of the social life of human groups and individuals including Anthropology, Communication studies The term liberal arts refers to a particular type of educational Curriculum broadly defined as a Classical education. The humanities are academic disciplines which study the Human condition, using methods that are primarily Analytic, Critical, or Speculative Theology is the study of a god or the gods from a religious perspective ) on the other. Though Mathematics, statistics, and computer science are not considered natural sciences, they provide many tools and frameworks used within the natural sciences. Mathematics is the body of Knowledge and Academic discipline that studies such concepts as Quantity, Structure, Space and Statistics is a mathematical science pertaining to the collection analysis interpretation or explanation and presentation of Data. Computer science (or computing science) is the study and the Science of the theoretical foundations of Information and Computation and their

Alongside this traditional usage, the phrase natural sciences is also sometimes used more narrowly to refer to its everyday usage, that is, related to natural history. Natural history is the Scientific research of Plants or Animals leaning more towards the Observational than Experimental methods In this sense "natural sciences" may refer to the biology and perhaps also the earth sciences, as distinguished from the physical sciences, including astronomy, physics, and chemistry. Foundations of modern biology There are five unifying principles Earth science (also known as geoscience, the geosciences or the Earth Sciences) is an all-embracing term for the Sciences related to the planet Physical science is an encompassing term for the branches of Natural science and Science that study non-living systems in contrast to the biological sciences Astronomy (from the Greek words astron (ἄστρον "star" and nomos (νόμος "law" is the scientific study Physics (Greek Physis - φύσις in everyday terms is the Science of Matter and its motion. Chemistry (from Egyptian kēme (chem meaning "earth") is the Science concerned with the composition structure and properties

Within the natural sciences, the term hard science is sometimes used to describe those sub-fields that rely on experimental, quantifiable data or the scientific method and focus on accuracy and objectivity. Hard science is a term used to describe Natural sciences and Physical sciences as distinct from Social science. Quantification has two distinct meanings In Mathematics and Empirical science, it refers to human acts known as Counting and Measuring Scientific method refers to bodies of Techniques for investigating phenomena These usually include physics, chemistry and many of the sub-fields of biology. By contrast, soft science is often used to describe the scientific fields that are more reliant on qualitative research, including the social sciences. Soft science is a colloquial term often used for Academic Research or Scholarship which is purportedly "scientific" however it is not based

There is some research, collectivelly known as graphism thesis, that indicates that natural science relies on graphs more than soft sciences and mathematics do. In Sociology of science, the graphism thesis is a proposition of Bruno Latour that Graphs are important in science In Computer science, a graph is a kind of Data structure, specifically an Abstract data type (ADT that consists of a set of nodes (also called

History

Prior to the 17th century, the objective study of nature was known as natural philosophy. For the current in the 19th century German idealism see Naturphilosophie Natural philosophy or the philosophy of nature (from Over the next two centuries, however, a philosophical interpretation of nature was gradually replaced by a scientific approach using inductive methodology. Induction or inductive reasoning, sometimes called inductive logic, is the process of Reasoning in which the premises of an argument are believed The works of Sir Francis Bacon popularized this approach, thereby helping to forge the scientific revolution. Francis Bacon 1st Viscount St Alban KC QC (22 January 1561 – 9 April 1626 was an English Philosopher, Statesman, and author The period which many historians of science call the Scientific Revolution can be roughly dated as having begun in 1543 the year in which Nicolaus Copernicus published

By the 19th century the study of science had come into the purview of professionals and institutions, and in so doing it gradually acquired the more modern name of natural science. The term scientist was coined by William Whewell in an 1834 review of Mary Somerville's On the Connexion of the Sciences. William Whewell ( May 24, 1794 &ndash March 6, 1866) was an English Polymath, Scientist, Anglican Priest Mary Somerville' ( December 26, 1780 &ndash November 28, 1872) was a Scottish Science writer and Polymath However the word did not enter general use until nearly the end of the same century.

According to a famous 1923 textbook Thermodynamics – and the Free Energy of Chemical Substances by the American chemist Gilbert N. Lewis and the American physical chemist Merle Randall, the natural sciences contain three great branches:

Aside from the logical and mathematical sciences, there are three great branches of natural science which stand apart by reason of the variety of far reaching deductions drawn from a small number of primary postulates – they are the mechanics, electrodynamics, and thermodynamics. Gilbert Newton Lewis ( October 23, 1875 - March 23, 1946) was a famous American physical chemist known for the discovery Merle Randall (1888-1950 was an American Physical chemist famous for his work over the period of 25 years in measuring free energy calculations of compounds with Mechanics ( Greek) is the branch of Physics concerned with the behaviour of physical bodies when subjected to Forces or displacements Classical electromagnetism (or classical electrodynamics) is a theory of Electromagnetism that was developed over the course of the 19th century most prominently In Physics, thermodynamics (from the Greek θερμη therme meaning " Heat " and δυναμις dynamis meaning "

Astronomy (from the Greek words astron (ἄστρον "star" and nomos (νόμος "law" is the scientific study The Solar System consists of the Sun and those celestial objects bound to it by Gravity. Daedalus is a prominent crater located near the center of the far side of the Moon. Far Side of the Moon, in original French, La face cachée de la lune, is a 2003 film by Robert Lepage.

This discipline is the science of celestial objects and phenomena that originate outside the Earth's atmosphere. s are significant physical entities, associations or structures which current Science has confirmed to exist in Space. A phenomenon (from Greek φαινόμενoν, pl φαινόμενα - phenomena) is any observable occurrence Temperature and layers The temperature of the Earth's atmosphere varies with altitude the mathematical relationship between temperature and altitude varies among five It is concerned with the evolution, physics, chemistry, meteorology, and motion of celestial objects, as well as the formation and development of the universe.

While the origins of the study of celestial features and phenomenon can be traced back to antiquity, the scientific methodology of this field began to develop in the middle of the seventeenth century. A key factor was Galileo's introduction of the telescope to examine the night sky in more detail. Galileo Galilei (15 February 1564 &ndash 8 January 1642 was a Tuscan ( Italian) Physicist, Mathematician, Astronomer, and Philosopher The mathematical treatment of astronomy began with Newton's development of celestial mechanics and the laws of gravitation, although it was triggered by earlier work of astronomers such as Kepler.

Biology

Main article: Biology

This field encompasses a set of disciplines that examines phenomena related to living organisms. Foundations of modern biology There are five unifying principles A phenomenon (from Greek φαινόμενoν, pl φαινόμενα - phenomena) is any observable occurrence The scale of study can range from sub-component biophysics up to complex ecologies. Biophysics (also biological physics) is an Interdisciplinary Science that employs and develops theories and methods of the Physical sciences for Ecology (from Greek grc οἶκος oikos, "house(hold" and grc -λογία -logia) is the scientific study of Biology is concerned with the characteristics, classification and behaviors of organisms, as well as how species were formed and their interactions with each other and the environment. Behavior or behaviour (see spelling differences) refers to the actions or Reactions of an object or Organism, usually In Biology, a species is one of the basic units of Biological classification and a Taxonomic rank. See also Natural environment The '''biophysical''' environment is the symbiosis between the physical environment and the Biological

The biological fields of botany, zoology, and medicine date back to early periods of civilization, while microbiology was introduced in the 17th century with the invention of the microscope. Botany, plant science(s, phytology, or plant biology is a branch of Biology and is the scientific study of plant Life Zoology (from Greek ζῷον, zoon, "animal" + λόγος, " Logos " "knowledge" is the branch of Medicine is the art and science of healing It encompasses a range of Health care practices evolved to maintain and restore Human Health by the Microbiology (from Greek grc μῑκρος mīkros, "small" grc βίος bios, " Life " and grc -λογία However it was not until the 19th century that biology became a unified science; once scientists discovered commonalities between all living things it was decided they were best studied as a whole. Some key developments in the science of biology were the discovery of genetics; Darwin's theory of evolution through natural selection; the germ theory of disease and the application of the techniques of chemistry and physics at the level of the cell or organic molecule. Genetics (from Ancient Greek grc-Latn genetikos, “genitive” and that from grc-Latn genesis, “origin” a discipline of Biology, is Charles Robert Darwin (February 12 1809 &ndash April 19 1882 was an English naturalist, who realised and demonstrated that all Species of life eVolution is the third Album by eLDee, it was due to be released in 2008 Natural selection is the process by which favorable Heritable traits become more common in successive Generations of a Population of The germ theory, also called the pathogenic theory of medicine, is a Theory that proposes that Microorganisms are the cause of many Diseases.

Modern Biology is divided into sub-disciplines by the type of organism and by the scale being studied. Molecular biology is the study of the fundamental chemistry of life, while cellular biology is the examination of the cell; the basic building block of all life. Molecular biology is the study of Biology at a molecular level See also List of basic cell biology topics.

Physics embodies the study of the fundamental constituents of the universe, the forces and interactions they exert on one another, and the results produced by these interactions. The Universe is defined as everything that Physically Exists: the entirety of Space and Time, all forms of Matter, Energy In Physics, a force is whatever can cause an object with Mass to Accelerate. In general, physics is regarded as the fundamental science as all other natural sciences utilize and obey the principles and laws set down by the field. Physics relies heavily on mathematics as the logical framework for formulation and quantification of principles. Mathematics is the body of Knowledge and Academic discipline that studies such concepts as Quantity, Structure, Space and

The study of the principles of the universe has a long history and largely derives from direct observation and experimentation. The formulation of theories about the governing laws of the universe has been central to the study of physics from very early on, with philosophy gradually yielding to systematic, quantitative experimental testing and observation as the source of verification. Philosophy is the study of general problems concerning matters such as existence knowledge truth beauty justice validity mind and language Key historical developments in physics include Isaac Newton's theory of universal gravitation and classical mechanics, an understanding of electricity and it's relation to magnetism, Einstein's theories of special and general relativity, the development of thermodynamics, and the quantum mechanical model of atomic and subatomic physics.

Cross-disciplines

The distinctions between the natural science disciplines are not always sharp, and they share a number of cross-discipline fields. Physics plays a significant role in the other natural sciences, as represented by astrophysics, geophysics, physical chemistry and biophysics. Astrophysics is the branch of Astronomy that deals with the Physics of the Universe, including the physical properties ( Luminosity, Geophysics, a major discipline of Earth sciences, is the study of the Earth by quantitative physical methods especially by seismic, electromagnetic Physical chemistry, is the application of Physics to macroscopic microscopic atomic subatomic and particulate phenomena in chemical systems It is mostly defined as a large Biophysics (also biological physics) is an Interdisciplinary Science that employs and develops theories and methods of the Physical sciences for Likewise chemistry is represented by such fields as biochemistry, geochemistry and astrochemistry. Biochemistry is the study of the chemical processes in living Organisms It deals with the Structure and function of cellular components such as The field of geochemistry involves study of the chemical composition of the Earth and other Planets chemical processes and reactions that govern the composition Astrochemistry is the study of the Chemical elements found in outer space generally on larger scales than the Solar System, particularly in molecular gas clouds

A particular example of a scientific discipline that draws upon multiple natural sciences is environmental science. Environmental science is the study of interactions among physical chemical and biological components of the environment. This field studies the interactions of physical, chemical and biological components of the environment, with a particular regard to the effect of human activities and the impact on biodiversity and sustainability. See also Natural environment The '''biophysical''' environment is the symbiosis between the physical environment and the Biological Biodiversity is the variation of Life forms within a given Ecosystem, Biome or for the entire Earth. Sustainability, in a general sense is the capacity to maintain a certain process or state indefinitely This science also draws upon expertise from other fields such as economics, law and social sciences.

A comparable discipline is oceanography, as it draws upon a similar breadth of scientific disciplines. Oceanography (from the greek words Ωκεανός meaning Ocean and γράφω meaning to write also called oceanology or Oceanography is sub-categorized into more specialized cross-displines, such as physical oceanography and marine biology. Physical oceanography is the study of physical conditions and physical processes within the Ocean, especially the motions and physical properties of ocean waters Marine biology is the scientific study of living Organisms in the Ocean or other marine or Brackish bodies of water As the marine ecosystem is very large and diverse, marine biology is further divided into many subfields, including specializations in particular species. Marine ecosystems are among of the earth's Aquatic ecosystems They include Oceans Salt marshes estuaries Lagoons, rocky Subtidal In Biology, a species is one of the basic units of Biological classification and a Taxonomic rank.

There are also a subset of cross-disciplinary fields which, by the nature of the problems that they address, have strong currents that run counter to specialization. Put another way: In some fields of integrative application, specialists in more than one field are a key part of most dialog. Such integrative fields, for example, include nanoscience, astrobiology, and complex system informatics. Nanotechnology, sometimes shortened to nanotech, refers to a field of Applied science whose theme is the control of matter on an Atomic and Molecular Astrobiology (from Greek grc ἄστρον astron, "constellation star" grc βίος bios, "life" and grc -λογία This article describes complex system as a type of system For other meanings see Complex systems. Informatics is the science of Information, the practice of Information processing, and the engineering of Information systems.
