; 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 one attempts to pass unpolarized light through the linear polarizer, only light that has its electric field at the positive 45 ° angle leaves the linear polarizer and enters the quarter-wave plate.

When the light went their way, they went on across the street.

When she made it, the results, starring Margaret Rutherford, were popular and successful light comedies, but were disappointing to Christie herself ; nevertheless, Agatha Christie dedicated the novel The Mirror Crack'd from Side to Side to Rutherford.

When the telescope is at position E it must be oriented toward spot S ′ so that the star light enters the telescope at spot S ′.

When the particles are in great motion, they produce a Doppler shift for measuring wind speed in the laser light, which is used to calculate the speed of the particles, and therefore the air around the anemometer.

When the wind blows horizontally, it presses on and moves the ball ; because ping-pong balls are very lightweight, they move easily in light winds.

When Congress overrode his veto, the project had its green light and ground was first broken in 1991.

When light is sent through the sample, it is backscattered by the particles / droplets.

When exposed to sunlight, artificial light, or infrared radiation ( even the heat of a hand nearby can be enough ), the vanes turn with no apparent motive power, the dark sides retreating from the radiation source and the light sides advancing.

When the radiometer is heated in the absence of a light source, it turns in the forward direction ( i. e. black sides trailing ).

When looking at a cross section of a beam of light, the length over which the phase is correlated is called the transverse coherence length.

When open, doors admit people, animals, ventilation, and light.

) 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 writing solo passages for the bass in orchestral or chamber music, composers typically ensure the orchestration is light so it doesn't obscure the bass.

When an electron in an excited molecule or atom descends to a lower energy level, it emits a photon of light equal to the energy difference.

When Loki, god of mischief and strife, murdered Baldr, god of beauty and light, he was punished by being bound in a cave with a poisonous serpent placed above his head dripping venom.

When light is sent through the sample, it is backscattered by the droplets.

When the frequency of the strobe equals the frequency of the rotating or vibrating object, the object completes one cycle of oscillation and returns to its original position between the flashes of light, so when illuminated by the strobe the object appears stationary.

When moving from a denser medium into a less dense one ( i. e., n < sub > 1 </ sub > > n < sub > 2 </ sub >), above an incidence angle known as the critical angle, all light is reflected and R < sub > s </ sub > = R < sub > p </ sub > = 1.

When light makes multiple reflections between two or more parallel surfaces, the multiple beams of light generally interfere with one another, resulting in net transmission and reflection amplitudes that depend on the light's wavelength.

When this material condenses in the rain, it forms dust and light sandy materials that resembles ground pumice.

When Heidegger and Sartre speak of a contrast between being and existence, they may be right, I don't know, but their language is too philosophical for me.

When they express themselves it is incandescent hatred that shines forth, the rage of repudiation, the ecstasy of negation.

When their faith in civil liberties is tested against strong pressures of social expediency in specific issues, e.g., suppression of `` dangerous ideas '', many waver and give in.

There is, of course, nothing new about dystopias, for they belong to a literary tradition which, including also the closely related satiric utopias, stretches from at least as far back as the eighteenth century and Swift's Gulliver's Travels to the twentieth century and Zamiatin's We, Capek's War With The Newts, Huxley's Brave New World, E. M. Forster's `` The Machine Stops '', C. S. Lewis's That Hideous Strength, and Orwell's Nineteen Eighty-Four, and which in science fiction is represented before the present deluge as early as Wells's trilogy, The Time Machine, `` A Story Of The Days To Come '', and When The Sleeper Wakes, and as recently as Jack Williamson's `` With Folded Hands '' ( 1947 ), the classic story of men replaced by their own robots.

When I first came across Samuel Johnson's pronouncement, `` the remedy for the ills of life is palliative rather than radical '', it seemed to me to sum up the profoundest of political and social truths.
