When describing graviton interactions, the classical theory ( i. e., the tree diagrams ) and semiclassical corrections ( one-loop diagrams ) behave normally, but Feynman diagrams with two ( or more ) loops lead to ultraviolet divergences ; that is, infinite results that cannot be removed because the quantized general relativity is not renormalizable, unlike quantum electrodynamics.

When a student is taking western classical music lessons, music teachers often spend some time explaining the different eras of western classical music, such as the Baroque era, the Classical era, the Romantic era, and the Modern era, because each era is associated with different styles of music and different performance practice techniques.

When Hauser delivered the new instrument Segovia had ordered, Segovia passed his 1928 Hauser to his U. S. representative and close friend Sophocles Papas, who gave it to his classical guitar student, the famous jazz and classical guitarist Charlie Byrd, who used it on several records.

When Chekov flees detention aboard the aircraft carrier, Rosenman wrote a bright cue that incorporates classical Russian compositions.

When the Spanish conquistadores came to South America, they brought the vihuela ( an ancestor of the classical guitar ) with them.

When he was 11 or 12, he was adopted by Joseph W. Clokey, a classical music composer and organist who taught music at Pomona College in Claremont, California.

When quantum mechanics was developed, it was seen to be a relation between the classical and quantum descriptions of a system using wave mechanics.

When the court moved to establish the Johor Sultanate, it continued using the classical language ; it has become so associated with Dutch Riau and British Johor that it is often assumed that the Malay of Riau is close to the classical language.

When the budget for the short grew very expensive Stokowski suggested to Disney that it would feature film with other pieces of classical music matched to animation.

When the quantum properties of gravity are not disregarded, spacetime itself becomes a quantum object, and therefore the usual logic of conventional quantum field theory, which requires the existence of a well defined classical geometry, does not work anymore.

When the mass is very large like a macroscopic object, the uncertainties and thus the quantum effect become very small, and classical physics is applicable.

When Madeleine of France was married to James V of Scotland, Ronsard was attached as a page in the Scottish court, where he was encouraged in the idea of making French vernacular translations of classical authors.

When Antonín Dvořák, a prominent Czech composer, visited the United States from 1892 to 1895, he iterated the idea that American classical music needed its own models instead of imitating European composers ; he helped to inspire subsequent composers to make a distinctly American style of classical music.

" When RCA later issued classical stereo albums ( in 1958 ), they used the prefix " LSC.

When economy recovered in 1920s, these architects and their followers continued working in primarily modernist environment ; some ( Zholtovsky ) strictly followed the classical canon, others ( Fomin, Schuko, Ilya Golosov ) developed their own modernized styles.

When these sets ( or the motions on them ), are harder to describe than the classical geometric objects, then the attractor is a strange attractor, as described in the section below.

When finer levels of detail are required, potentials based on quantum mechanics are used ; some techniques attempt to create hybrid classical / quantum potentials where the bulk of the system is treated classically but a small region is treated as a quantum system, usually undergoing a chemical transformation.

When discussing the information that is contained in physical systems according to modern quantum physics, we must distinguish between classical information and quantum information.

When the energy is simply the kinetic energy of the particle

When a symbol is not marked by any of the three grammar symbols ( square, cone, inverted cone ), they may be a non material thing, a grammatical particle, etc.

When the particle moves, its velocity is

When calculating scattering cross sections in particle physics, the interaction between particles can be described by starting from a free field which describes the incoming and outgoing particles, and including an interaction Hamiltonian to describe how the particles deflect one another.

When a particle falls into a black hole, it is boosted relative to an outside observer, and its gravitational field assumes a universal form.

; Quantum mechanics or Particle physics: When a spinless particle ( or even an unpolarized particle with spin ) decays, the resulting decay distribution must be isotropic in the rest frame of the decaying particle regardless of the detailed physics of the decay.

When this particle is absent, the infinitive is said to be a bare infinitive ; when it is present, it is generally considered to be a part of the infinitive, then known as the full infinitive ( or to-infinitive ), and there is a controversy about whether it should be separated from the main word of the infinitive ( see Split infinitive ).

When we perform the experiment, the probability of obtaining two particles in the state is now 0. 33 ; the probability of obtaining two particles in the state is 0. 33 ; and the probability of obtaining one particle in the state and the other in the state is 0. 33.

When we perform the experiment, we inevitably find that one particle is in the state and the other is in the state.

When a charged particle moves through a magnetic field B, it feels a Lorentz force F given by the cross product:

When it was found in 1900 by Max Planck that the energy of waves could be described as consisting of small packets or " quanta ", Albert Einstein further developed this idea to show that an electromagnetic wave such as light could be described as a particle ( later called the photon ) with a discrete quantum of energy that was dependent on its frequency.

When one measures the position of the particle, it is impossible to predict with certainty the result.

When a ( positive ) alpha particle approached sufficiently close to the nucleus, it was repelled strongly enough to rebound at high angles.

When a particle is on the outside of the center on one of the curved sections, by the time it flows through the straight area and into the other curved section it is now on the inside of center.

When the force on the far particle is subtracted from the force on the near particle, this first term cancels, as do all other even-order terms.

When first discovered, particle diffraction was a source of great puzzlement.

When passing through matter, a beta particle is decelerated by electromagnetic interactions and may give off bremsstrahlung x-rays.

:: When sand-sized particles are deposited, the space between the sand grains either remains open or is filled with mud ( silt and / or clay sized particle ).

When Einstein published his seminal 1905 paper on the particle theory of light, Millikan was convinced that it had to be wrong, because of the vast body of evidence that had already shown that light was a wave.

When we see the particle detectors flash or hear the click of a Geiger counter then Everett's theory interprets this as our wavefunction responding to changes in the detector's wavefunction, which is responding in turn to the passage of another wavefunction ( which we think of as a " particle ", but is actually just another wave-packet ).

When an object rotates about its axis, the motion cannot simply be analyzed as a particle, since in circular motion it undergoes a changing velocity and acceleration at any time ( t ).
