There is a lack of experimental evidence relating to quantum gravity, and classical physics adequately describes the observed effects of gravity over a range of 50 orders of magnitude of mass, i. e., for masses of objects from about 10 < sup >− 23 </ sup > to 10 < sup > 30 </ sup > kg.

At present, one of the deepest problems in theoretical physics is harmonizing the theory of general relativity, which describes gravitation, and applies to large-scale structures ( stars, planets, galaxies ), with quantum mechanics, which describes the other three fundamental forces acting on the atomic scale.

This model describes, in low enough energies, a quantum gravity theory, which also includes ( if open strings are incorporated as well ) gauge fields such as the photon ( or, in more general terms, any gauge theory ).

The Schrödinger equation describes the wave-like behavior of particles in quantum mechanics.

Although it is not a successful relativistic generalization of the Schrödinger equation, this equation is resurrected in the context of quantum field theory, where it is known as the Klein – Gordon equation, and describes a spinless particle field ( e. g. pi meson ).

In fact, as far as prediction goes, the quantum development is at least as predictable as the classical motion, but the key is that it describes wave functions that cannot be easily expressed in ordinary language.

This does not mean that quantum mechanics describes the world as more deterministic, unless one already considers the wave function to be the true reality.

The world around us seems to be in a specific state, but quantum mechanics describes it by wave functions that govern the probability of all values.

It is evident from this double-slit experiment with an ensemble of individual electrons that, since the quantum mechanical wave function ( absolutely squared ) describes the completed interference pattern, it must describe an ensemble.

Consequently, if quantum mechanics is to be a complete theory, relational quantum mechanics argues that the notion of " state " describes not the observed system itself, but the relationship, or correlation, between the system and its observer ( s ).

The doctrine of five phases describes two cycles of balance, a generating or creation ( 生, shēng ) cycle and an overcoming or destruction ( 克 / 剋, kè ) cycle of interactions between the phases.

The DM selects and describes the various non-player characters ( NPCs ), the party encounters, the settings in which these interactions occur, and the outcomes of those encounters based on the players ' choices and actions.

However, since string theory also describes gravitational interactions, one expects the low-energy theory to describe particles moving in gravitational backgrounds.

Gell-Mann, along with Maurice Lévy, developed the sigma model of pions, which describes low energy pion interactions.

Weak emergence describes new properties arising in systems as a result of the interactions at an elemental level.

Because pragmatics describes generally the forces in play for a given utterance, it includes the study of power, gender, race, identity, and their interactions with individual speech acts.

Integrated geography, integrative geography or human-environmental geography is the branch of geography that describes and explains the spatial aspects of interactions between humans and the natural world.

Andrea McCrea describes Hall's interactions with Robert Dallington, and then Healey, against the background of a few years of the pace-setting culture of the court of Henry Frederick, Prince of Wales.

In microeconomics, bandwagon effect describes interactions of demand and preference.

Vatsyayana's Kama Sutra is valuable today for his psychological insights into the interactions and scenarios of love, and for his structured approach to the many diverse situations he describes.

It describes interactions where the fitness of one species has absolutely no effect whatsoever on that of the other.

Facilitation describes species interactions that benefit at least one of the participants and cause no harm to either.

He describes the postulated interactions as constituting a " society of mind ", hence the title.

In this paper, North defines institutions as “ humanly devised constraints that structure political, economic and social interactions .” Constraints, as North describes, are devised as formal rules ( constitutions, laws, property rights ) and informal restraints ( sanctions, taboos, customs, traditions, code of conduct ), which usually contribute to the perpetuation of order and safety within a market or society.

The transactional interpretation of quantum mechanics ( TIQM ) describes quantum interactions in terms of a standing wave formed by retarded ( forward-in-time ) and advanced ( backward-in-time ) waves.

Each use case describes an event that may occur for a short period of time in real life, but may consist of intricate details and interactions between the actor and the world.

* denotes the interaction Hamiltonian which describes the interactions in the theory.

The quantum operation formalism describes not only unitary time evolution or symmetry transformations of isolated systems, but also the effects of measurement and transient interactions with an environment.

Polarization density also describes how a material responds to an applied electric field as well as the way the material changes the electric field, and can be used to calculate the forces that result from those interactions.
