When he had stored his stock in the great oak chest, locked the two big hasps and secured the additional chain, tied the fly of the tent, and picked up the cash box, he moved up the darkening street.

When McFeeley was halfway to the door, the proprietor emerged -- a mountainous, dark man, his head thick with resiny black hair, his eyes like two of the black olives he imported in boatloads.

`` When Konishi gets back with the jeep, I want you to round up two or three Japanese boys.

When the boat had touched, the weaker ones and the two wounded men had been lifted out and carried away by the soldiers.

When he showed this model as his `` solution '' as to how the Howe sewing machine operated, he was told he was `` wrong '', and discovered to his amazement that the Howe Machine, which was unknown to him in detail, used two threads while the one that he had perfected used only one.

When more than two figures are separated by subtraction symbols the subtraction must be carried out from the left to right if the result is to be correct.

When a question contains two verbs, the response does not make clear which of them is being answered.

When the early part of the gradient was flattened, either by using the gradient shown in Fig. 2 or by allowing the `` cone-sphere '' gradient to become established more slowly, Region 2 activity could sometimes be separated into two areas ( donors P. J. and R. S., Fig. 1 and E. M., Fig. 2 ).

When it comes to rate of early growth, the Indian python leads with a figure of about 3 feet 6 inches per year for the first two years, more or less.

When, as in this case, the two forms match, the address Af is saved to represent the occurrence Af.

When ity is added, real clearly has two syllables.

When now we count the frequency of the 71 items in the two language families appearing in the same column or grade, or one column or grade apart, or two or three or four, we find these differences: Af

When the power of the latter was made both limited and explicit -- when norms were clarified and made more precise and the creation of new norms was placed exclusively in parliamentary hands -- two purposes were served: Government was made subservient to an institutionalized popular will, and law became a rational system for implementing that will, for serving conscious goals, for embodying the `` public policy ''.

When he realized she was dead, he called two lawyers and then the police.

When the police arrived, they found McClellan and the two lawyers sitting and staring silently.

When the visitors, after losing this game, rode along the village streets toward home, the youngsters who could keep abreast of them for a moment or two screamed triumphantly, `` You bunch of hay-shakers!!

When the two cars were equidistant from him, the station wagon started up again and the Ford gathered speed.

Read the next two verses: `` When the wicked, even mine enemies and my foes, came upon me to eat up my flesh, they stumbled and fell.

When oscillating electric currents flow at the correct voltages within radio antennas, radio waves are generated.

When these vessels of a new model were built, which were intended to " clip " over the waves rather than plough through them, the improved type of craft became known as " clippers " because of their speed.

When waves are added together, their sum is determined by the relative phases as well as the amplitudes of the individual waves so that the summed amplitude of the waves can have any value between zero and the sum of the individual amplitudes.

) When Thomas Young first demonstrated this phenomenon, it indicated that light consists of waves, as the distribution of brightness can be explained by the alternately additive and subtractive interference of wavefronts.

When the source of the waves is moving toward the observer, each successive wave crest is emitted from a position closer to the observer than the previous wave.

When a single photon is sent through an interferometer, it passes through both paths, interfering with itself, as waves do, yet is detected by a photomultiplier or other sensitive detector only once.

When EM radiation at the frequences for which it is referred to as " radio waves " impinges upon a conductor, it couples to the conductor, travels along it, and induces an electric current on the surface of the conductor by moving the electrons of the conducting material in correlated bunches of charge.

When processing signals, such as audio, radio waves, light waves, seismic waves, and even images, Fourier analysis can isolate individual components of a compound waveform, concentrating them for easier detection and / or removal.

When the stone hits the surface of the water, a circular pattern of waves appears.

When inserted together with a galvanometer, into a tuned electrical circuit, it could be used as a very sensitive rectifying detector of high frequency wireless currents, known as radio waves.

When he came into view, waves of sound began to build throughout the stadium, rising to a roar, then to a thunder.

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 the waves are steep, it may be necessary to sail closer to the wind to avoid waves directly on the beam.

When large tidal flows enter the Strait and the high tide relaxes, internal waves are generated at the Camarinal Sill and proceed eastwards.

When he added cylindrical reflectors behind his dipole antennas, Hertz could detect radio waves about 20 metres from the transmitter in his laboratory.

When this outflow of material eventually impacts the surrounding gas, the shock waves that are created compress and heat the gas.

When the propagation speed of these electromagnetic waves was calculated, the speed of light fell out.

When a medium is nonlinear, the response to complex waves cannot be determined from a sine-wave decomposition.
