When words can be used in a more fresh and primitive way so that they strike with the force of sights and sounds, when tones of sound and colors of paint and the carven shape all strike the sensibilities with an undeniable force of data in and of themselves, compelling the observer into an attitude of attention, all this imitates the way experience itself in its deepest character strikes upon the door of consciousness and clamors for entrance.

When both are focused at infinity the light path between them is parallel ( afocal ), allowing the camera to basically photograph anything the observer can see.

When the external form undergoes the greatest change, as from an aquatic insect to a flying gnat, a caterpillar to a crysalis, a crysalis to a butterfly, or a tadpole to a frog, there is nothing new in the organization ; all the parts of the gnat, the butterfly, and the frog, having really existed, though not appearing to the common observer in the forms in which they are first seen.

Translating this analogy into space, then, a " stationary " observer sees a planet moving left at speed U and a spaceship moving right at speed v. If the spaceship has the proper trajectory, it will pass close to the planet, moving at speed U + v relative to the planet's surface because the planet is moving in the opposite direction at speed U. When the spaceship leaves orbit, it is still moving at U + v relative to the planet's surface but in the opposite direction ( to the left ).

When some probe ( such as a light ray or an observer ) approaches a black hole event horizon, its Schwarzschild time coordinate grows infinite.

When Digitaria is closest to Sirius, that star brightens: when it is farthest from Sirius, it gives off a twinkling effect that suggests to the observer several stars.

* Motion parallax – When an observer moves, the apparent relative motion of several stationary objects against a background gives hints about their relative distance.

When sodium ( Na ) and chlorine ( Cl ) are combined, the sodium atoms each lose an electron, forming cations ( Na < sup >+</ sup >), and the chlorine atoms each gain an electron to form anions ( Cl < sup >−</ sup >).

When they encounter an infection site the particles gain a positive charge provoked by the slightly acidic environment at the infection sites, allowing them to bind to the negatively charged bacterial cell walls and release antibiotics at locally high concentration.

When negative feedback is used, the circuit's overall gain and response becomes determined mostly by the feedback network rather than by the op-amp itself.

When you add wild cards, the stronger hands gain frequency while the weaker hands lose frequency.

When the primus pilus retired he would most likely gain entry into the equestrian class.

When the Dominion forces suddenly withdrew into Cardassian territory, the Allies realized that they were withdrawing in order to gain time to recover from their battle wounds, so that they could come back stronger a few years later.

When triodes were first used in radio transmitters and receivers, it was found that tuned amplification stages had a tendency to oscillate unless their gain was very limited.

When he's a servant, he will either serve his master devotedly or look for every opportunity to ruin and take advantage of him as he happens to see fit — whatever will gain the greatest advantage for himself and himself alone.

When his rebellion failed to gain the support of Germany's aristocracy, Henry II was forced to abandon his claims to the throne and to allow Otto III's mother Theophanu, who would serve as regent until 991.

When the non-inverting input ( V +) is at a higher voltage than the inverting input ( V -), the high gain of the op-amp causes the output to saturate at the highest positive voltage it can output.

When the transfer function comprises only a perfect gain constant A and perfect delay T

When describing an amplifier, the more common term is gain.

When power gain is calculated using voltage instead of power, making the substitution ( P = V < sup > 2 </ sup >/ R ), the formula is:
