Philosophy of physics Philosophy of physics In physics and philosophy, absolute theory usually refers to a theory based on concepts (such as the concept of space) that exist independently of other concepts and objects. An absolute theory is the opposite of a relational theory. ...more on Wikipedia about "Absolute theory"
Ansatz is a German language term often used by physicists and mathematicians. An ansatz is an assumed form for a mathematical function that is not based on any underlying theory or principle. ...more on Wikipedia about "Ansatz"
Closure of Physics is the principle that all physical things - physical bodies and physical systems - are completely bound and describable by physical laws. This position is opposed to a dualist principle of interaction between mind (spirit) and body (matter). ...more on Wikipedia about "Closure of Physics"
In physics, the Elitzur-Vaidman bomb-testing problem is a thought-experiment in quantum mechanics, first proposed by Avshalom Elitzur and Lev Vaidman in 1993. It employs quantum superposition in order to construct a mechanism for ascertaining whether a measurement has taken place. ...more on Wikipedia about "Elitzur-Vaidman bomb-testing problem"
FAPP is an abbervation of "For All Practical Purposes", a pragmatic approach toward the problem of incompleteness of every scientific theory and the usage of asymptotical approximations. ...more on Wikipedia about "FAPP"
In physics, interaction-free measurement is a type of measurement in quantum mechanics that detects the position or state of an object without an interaction occurring between it and the measuring device. Examples include the Renninger negative-result experiment, the Elitzur-Vaidman bomb-testing problem, and certain double-cavity optical systems. ...more on Wikipedia about "Interaction-free measurement"
Description: The Philosophiae Naturalis Principia Mathematica ( Latin: "mathematical principles of natural philosophy", often Principia or Principia Mathematica for short) is a three-volume work by Isaac Newton published on July 5, 1687. Probably the most influential scientific book ever published, it contains the statement of Newton's laws of motion forming the foundation of classical mechanics as well as his law of universal gravitation. He derives Kepler's laws for the motion of the planets (which were first obtained empirically). ...more on Wikipedia about "List of publications in physics"
Macroscopic is commonly used to describe physical objects that are measurable and observable by the naked eye. When applied to phenomena and abstract objects, it describes existence in the world as we perceive it. Lengths scales generally considered macroscopic roughly fall in the range 1 mm - 1 km. ...more on Wikipedia about "Macroscopic"
Nothing comes from nothing is a philosophical expression often stated in its Latin form: ex nihilo nihil fit. This principle maintains that anything that exists in physical reality has its origins in and is the manifestation of something else. The idea was first expressed as such by Empedocles. Today, the idea is loosely associated with the laws of conservation of mass and energy. ...more on Wikipedia about "Nothing comes from nothing"
In mathematical physics or theories of the physical world, an observerspace description can be a "literalist", "instrumentational" or "experiental" interpretation of physical phenomenology, where what appears to be happening is taken as physical reality ("what you see is what is there" see also: " logical positivism"). ...more on Wikipedia about "Observerspace"
Classical Newtonian physics has, formally, been replaced by Quantum mechanics on the small scale and Relativity on the large scale. Because most humans continue to think in terms of the kind of events we perceive in the human scale of daily life, it became necessary to provide a new philosophical interpretation of classical physics. Classical mechanics worked extremely well within its domain of observation but made inaccurate predictions at very small scale - atomic scale systems - and when objects moved very fast or were very massive. Viewed through the lens of quantum mechanics or relativity, we can now see that classical physics, imported from the world of our everyday experience, includes notions for which there is no actual evidence. For example, that there exists one absolute time shared by all observers. Or the idea that electrons are discrete entities like miniature planets that circle the nucleus in definite orbits. . ...more on Wikipedia about "Philosophical interpretation of classical physics"
Philosophy of physics is the study of the fundamental, philosophical questions underlying modern physics, the study of matter and energy and how they interact. Perhaps the main questions concern the nature of space and time, atoms and atomism, cosmology, the interpretation of the results of quantum mechanics, the foundations of statistical mechanics, causality, determinism, and the nature of physical laws. Classically, several of these questions were studied as part of metaphysics (for example, those about causality, determinism, and space and time). Today, the philosophy of physics is very close to and the most active subtopic within philosophy of science. ...more on Wikipedia about "Philosophy of physics"
Philosophy of Space and Time is a branch of philosophy which deals with issues surrounding the ontology, epistemology and character of space and time. While this type of study has been central to philosophy from its inception, the philosophy of space and time, an inspiration for, and central to early analytic philosophy, focusses the subject into a number of basic issues. ...more on Wikipedia about "Philosophy of space and time"
A physical paradox is an apparent contradiction relating to physical descriptions of the universe. As such, there are many different uses for the term ranging from a challenging thought experiment that seems to believe common sense to an actual breakdown of the mathematical theory that describes the physical universe. While many physical paradoxes have accepted resolutions that make them little more than curiosities, others may defy resolution and be the result of an inadequate interpretation of the theory, an assumption about the physical world that is violated, or an indication that the theory inadequately describes the conditions. In physics as in all of science, contradictions and paradoxes are generally assumed to be artifacts of error and incompleteness because reality is assumed to be completely consistent, although this is itself a philosophical assumption. When, as in fields such as quantum physics and relativity theory, existing assumptions about reality have been shown to break down, this has usually been dealt with by changing our understanding of reality to a new one which remains self-consistent in the presence of the new evidence. ...more on Wikipedia about "Physical paradox"

A common misconception is that there is a principle of minimum energy. Many arguments in physics and chemistry are based on the notion that systems tend toward a state of minimum energy. For instance, it is often stated that a proton and an electron will find their most stable configuration when combined the ground state of a hydrogen atom, because that state's energy is 13.6 electron volts (eV) lower than when the two particles separated by an infinite distance. The actual reason this is the stable state is that the energy difference as the particles coalesce is given off as electromagnetic radiation, i.e. heat, which increases the entropy of the surroundings, ultimately joining the 2.7 Kelvin interstellar blackbody radiation left over from the Big Bang. The flow of heat from place to place, driven by temperature differences, produces even more entropy. It is the second law of thermodynamics which explains movement toward any stable state. In its most general and succinct form, the second law says that all spontaneous processes produce entropy. ...more on Wikipedia about "Principle of minimum energy"
In physics and philosophy, a relational theory is a framework to understand reality or a physical system in such a way that the position and other properties of the objects are only meaningful relatively to other objects. In a relational theory, space does not exist unless there are objects in it. ...more on Wikipedia about "Relational theory"
