When compressed, the crystal produces a small electrical current, so when placed under the bridge saddle, the vibrations of the strings through the saddle, and of the body of the instrument, are converted to a weak electrical signal.

When the string vibrates, the shape of the crystal is distorted, and the stresses associated with this change produce tiny voltages across the crystal that can be amplified and manipulated.

When an external electric field is applied to the liquid crystal, the dipole molecules tend to orient themselves along the direction of the field.

When an electric field is applied to the LC layer, the long molecular axes tend to align parallel to the electric field thus gradually untwisting in the center of the liquid crystal layer.

When this angle is exceeded, photons no longer penetrate the semiconductor but are instead reflected both internally inside the semiconductor crystal and externally off the surface of the crystal as if it were a mirror.

When the planes of an ionic bond slide past one another, the resultant change in location shifts ions of the same charge into close proximity, resulting in the cleavage of the crystal ; such shift is not observed in covalently bonded crystals where fracture and crystal fragmentation occurs.

When they land on a piece of film or other detector, these beams make a diffraction pattern of spots ; the strengths and angles of these beams are recorded as the crystal is gradually rotated.

When a crystal is mounted and exposed to an intense beam of X-rays, it scatters the X-rays into a pattern of spots or reflections that can be observed on a screen behind the crystal.

When the wedge was pushed down onto the surface of a crystal and voltage applied to the other side ( on the base of the crystal ), current started to flow from one contact to the other as the base voltage pushed the electrons away from the base towards the other side near the contacts.

When investigating the stability of crystal oscillators and atomic clocks it was found that they did not have a phase noise consisting only of white noise, but also of white frequency noise and flicker frequency noise.

When a crystal of ice-nine contacts liquid water, it becomes a seed crystal that makes the molecules of liquid water arrange themselves into the solid form, ice-nine.

When covalent bonds link long chains of atoms in large molecules, however ( as in polymers such as nylon ), or when covalent bonds extend in networks though solids that are not composed of discrete molecules ( such as diamond or quartz or the silicate minerals in many types of rock ) then the structures that result may be both strong and tough, at least in the direction oriented correctly with networks of covalent bonds.

When the field is removed, the quartz will generate an electric field as it returns to its previous shape, and this can generate a voltage.

When the rattles were shaken at night during ceremonies, the friction and mechanical stress of the quartz crystals impacting together produced flashes of light visible through the translucent buffalo hide.

When silicon is grown by the Czochralski method, the melt is contained in a silica ( quartz ) crucible.

When fitted with the optional " Rallye " Pack, the later models featured round headlights and quartz halogen driving lights.

When the bust was first discovered, Borchardt assumed that the quartz iris of the left eye had fallen out when the sculptor Thutmose's workshop fell into ruin, but an intensive search failed to locate it in the debris of the building.

When quartz content is greater than five percent the rock is classified as quartz latite.

When sandstone is metamorphosed to quartzite, the individual quartz grains recrystallize along with the former cementing material to form an interlocking mosaic of quartz crystals.

When the QCM was first developed, natural quartz was harvested, selected for its quality and then cut in the lab.

When quartz was mined, it was entwined with a mineral called feldspar, and the two had to be separated by hand.

When the rattles were shaken at night during ceremonies, the friction and mechanical stress of the quartz crystals impacting together produced flashes of light which partly shone through the translucent buffalo hide.

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 I try to work out my reasons for feeling that this passage is of critical significance, I come up with the following ideas, which I shall express very briefly here and revert to in a later essay.

When the proprietor dies, the establishment should become a corporation until it is either acquired by another proprietor or the government decides to drop it.

When the reactionary response is thus bolstered by an intellectual defense, the characteristics of that defense are explicable only in terms of the basic attitudes of unanalyzed reaction.

When I take over Taliesin, the first thing I'll do is fire you ''.

When someone in the audience rose and asked how does it feel to be a celebrity, Carl said, `` A celebrity is a fellow who eats celery with celerity ''.

When decision makers act within this frame they determine whether a claim put forward in the name of religion is to be accepted by the larger community as appropriate to religion.

When we consider the disorganized state of the world community, and the legacy of predispositions adversely directed against all who are identified as Jews, it is obvious that the struggle for the minds and muscles of men needs to be prosecuted with increasing vigor and skill.

When we turn to Aristotle's ideas on the moral measure of literature, it is at once apparent that he is at times equally concerned about the influence of the art.

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.

When we become firm enough to stand for those ideals which we know to be right, when we become hard enough to refuse to aid nations which do not permit self-determination, when we become strong enough to resist any more drifts towards socialism in our own Nation, when we recognize that our enemy is Communism not war, and when we realize that concessions to Communists do not insure peace or freedom, then, and only then will we no longer be `` soft ''.
