Physics (Greek Greek , an independent branch of the Indo-European family of languages, is the language of the Greeks. Native to the southern Balkans, it has the longest documented history of any Indo-European language, spanning 34 centuries of written records. In its ancient form, it is the language of classical ancient Greek literature and the New Testament of: physis Physis is a Greek theological, philosophical, and scientific term usually translated into English as "nature". In the Odyssey, Homer uses the word once (its earliest known occurrence), referring to the intrinsic way of growth of a particular species of plant. In other very early uses it had such a meaning: related to the natural growing – φύσις meaning "nature Nature, in the broadest sense, is equivalent to the natural world, physical world, or material world. "Nature" refers to the phenomena of the physical world, and also to life in general. It ranges in scale from the subatomic to the cosmic") is a natural science In science, the term natural science refers to a naturalistic approach to the study of the universe, which is understood as obeying rules or laws of natural origin; it is the study of matter Matter is a term that traditionally refers to the substance that all objects are made of. The common way to identify this "substance" is through its physical properties; a common definition of matter is anything that has mass and occupies a volume. However, this definition has to be revised in light of quantum mechanics, where the[1] and its motion In physics, motion is change in the location or position of a body. Change in motion is the result of an applied force. Motion is typically described in terms of velocity, acceleration, displacement, and time. An object's velocity cannot change unless it is acted upon by a force, as described by Newton's first law also known as Inertia. An object' through spacetime In physics, spacetime is any mathematical model that combines space and time into a single continuum. Spacetime is usually interpreted with space being three-dimensional and time playing the role of a fourth dimension that is of a different sort from the spatial dimensions. According to certain Euclidean space perceptions, the universe has three and all that derives from these, such as energy In physics, energy is a scalar physical quantity that describes the amount of work that can be performed by a force, an attribute of objects and systems that is subject to a conservation law. Different forms of energy include kinetic, potential, thermal, gravitational, sound, light, elastic, and electromagnetic energy. The forms of energy are and force In physics, the concept of force is used to describe how a massive body is affected by acceleration or mechanical stress. Force can also be described by intuitive concepts such as a push or pull that can cause an object with mass to change its velocity , i.e., to accelerate, or which can cause a flexible object to deform. Related concepts to.[2] More broadly, it is the general analysis of nature Nature, in the broadest sense, is equivalent to the natural world, physical world, or material world. "Nature" refers to the phenomena of the physical world, and also to life in general. It ranges in scale from the subatomic to the cosmic, conducted in order to understand how the world World is a common name for the sum of human civilization living, specifically human experience, history, or the 'human condition' in general, worldwide, i.e. anywhere on Earth. In a philosophical context, it may refer to the Universe, everything that constitutes reality. Some authors, such as Carl Sagan, use the term worlds to refer to heavenly and universe The Universe comprises everything we perceive to physically exist, the entirety of space and time, all forms of matter and energy, and the physical laws and constants that govern them. However, the term Universe may be used in slightly different contextual senses, denoting such concepts as the cosmos, the world, or Nature behave.[3][4]
Physics is one of the oldest academic disciplines, perhaps the oldest through its inclusion of astronomy Astronomy is the scientific study of celestial objects and phenomena that originate outside the Earth's atmosphere (such as the cosmic background radiation). It is concerned with the evolution, physics, chemistry, meteorology, and motion of celestial objects, as well as the formation and development of the universe.[5] Over the last two millennia, physics had been considered synonymous with philosophy Philosophy is the study of general and fundamental problems concerning matters such as existence, knowledge, values, reason, mind, and language. It is distinguished from other ways of addressing fundamental questions by its critical, generally systematic approach and its reliance on rational argument. The word "Philosophy" comes from the, chemistry Chemistry (from Arabic:الكيم Latinized: chem , meaning "earth") is the science concerned with the composition, behavior, structure, and properties of matter, as well as the changes it undergoes during chemical reactions. It is a physical science for studies of various atoms, molecules, crystals and other aggregates of matter whether, and certain branches of mathematics Mathematics is the study of quantity, structure, space, and change. Mathematicians seek out patterns, formulate new conjectures, and establish truth by rigorous deduction from appropriately chosen axioms and definitions and biology Biology is the natural science concerned with the study of life and living organisms, including their structure, function, growth, origin, evolution, distribution, and taxonomy, but during the Scientific Revolution In the history of science, the scientific revolution was a period when new ideas in physics, astronomy, biology, human anatomy, chemistry, and other sciences led to a rejection of doctrines that had prevailed from Ancient Greece through the Middle Ages, and laid the foundation of modern science. According to the majority of scholars, the in the 16th century, it emerged to become a unique modern science in its own right.[6] However, in some subject areas such as in mathematical physics Mathematical physics is the scientific discipline concerned with the interface of mathematics and physics. The Journal of Mathematical Physics defines it as: "the application of mathematics to problems in physics and the development of mathematical methods suitable for such applications and for the formulation of physical theories." and quantum chemistry Quantum chemistry is a branch of theoretical chemistry, which applies quantum mechanics and quantum field theory to address problems in chemistry. The description of the electronic behavior of atoms and molecules as pertaining to their reactivity is one of the applications of quantum chemistry. Quantum chemistry lies on the border between, the boundaries of physics remain difficult to distinguish.
Physics is both significant and influential, in part because advances in its understanding have often translated into new technologies, but also because new ideas in physics often resonate with the other sciences, mathematics and philosophy.
For example, advances in the understanding of electromagnetism Electromagnetism is the physics of the electromagnetic field, a field that exerts a force on charged particles and is reciprocally affected by the presence and motion of such particles or nuclear physics led directly to the development of new products which have dramatically transformed modern-day society (e.g., television Television is a widely used telecommunication medium for transmitting and receiving moving images, either monochromatic ("black and white") or color, usually accompanied by sound. "Television" may also refer specifically to a television set, television programming or television transmission. The word is derived from mixed Latin, computers A computer is a machine that manipulates data according to a set of instructions, domestic appliances A major appliance, or domestic appliance, is usually defined as a large machine which accomplishes some routine housekeeping task, which includes purposes such as cooking, food preservation, or cleaning, whether in a household, institutional, commercial or industrial setting. An appliance is differentiated from a plumbing fixture because it uses, and nuclear weapons A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission or a combination of fission and fusion. Both reactions release vast quantities of energy from relatively small amounts of matter; a modern thermonuclear weapon weighing little more than a thousand kilograms can produce an explosion); advances in thermodynamics In physics, thermodynamics is the study of energy conversion between heat and mechanical work, and subsequently the macroscopic variables such as temperature, volume and pressure. Its progenitor, based on statistical predictions of the collective motion of particles from their microscopic behavior, is the field of statistical thermodynamics (or led to the development of motorized transport; and advances in mechanics Mechanics is the branch of physics concerned with the behaviour of physical bodies when subjected to forces or displacements, and the subsequent effect of the bodies on their environment. The discipline has its roots in several ancient civilizations (see History of classical mechanics and Timeline of classical mechanics). During the early modern inspired the development of calculus Calculus is a branch in mathematics focused on limits, functions, derivatives, integrals, and infinite series. This subject constitutes a major part of modern mathematics education. It has two major branches, differential calculus and integral calculus, which are related by the fundamental theorem of calculus. Calculus is the study of change, in.

London, Feb 1 (ANI): Hollywood actress Anne Hathaway is not a big fan of fashion magazines, instead she prefers studying books by legendary scientist Albert Einstein and . physics. textbooks in her spare time.
Q. I'm presently an undergraduate sophomore majoring in physics and math. I was planning on studying particle physics in graduate school but lately have been hearing about the poor job outlooks in the field. What would be a more promising physics-related field?

A. Most of these are branches under applied physics. 1. Soil physics and Geophysics. Not so much a hot field anymore. Many still love this kind of work though. 2. Space physics. Space is probably the future it seems to be where we are going. 3. Communication physics. There will be tons of work in this field for at least the next 40-60 years at least. We thrive on communication, especially internet based. 4. Agrophysics. Not a lot of work in this field, but the work is very rewarding, what little there is. 5. Biophysics, Medical physics, and Sports physics. This seems to be very popular right now. Lots of work in this area, but the work is sometimes hard to find.
