If light moves instantaneously, the telescope does not move, and the true direction of the star relative to the observer can be found by following the line ES.

If the large-scale Universe appears isotropic as viewed from Earth, the cosmological principle can be derived from the simpler Copernican principle, which states that there is no preferred ( or special ) observer or vantage point.

If we are to specify this doctor's normality in sensory terms, we must make reference to a second doctor who, when inspecting the sense organs of the first doctor, would himself have to have the sense data a normal observer has when inspecting the sense organs of a subject who is a normal observer.

If the observer is at a lower gravitational potential than the source, a gravitational blueshift can be observed instead.

If these elements for any synoptic cloud level at the time of observation are deemed to be of equal importance, then the type which is predominant in amount is coded by the observer and plotted on the weather map.

If the ( light ) source, the massive lensing object, and the observer lie in a straight line, the original light source will appear as a ring around the massive lensing object.

If there is any misalignment the observer will see an arc segment instead.

If the observer is close to the surface of the earth, then it is valid to disregard h in the term, and the formula becomes

If the object is identity anonymity, nothing sent via a remailer can ever include identifying information in content available to an outside observer.

If an observer in the antumbra moves closer to the light source, the apparent size of the occluding body increases until it causes a full umbra.

If another object of the scene must be rendered in the same pixel, the method compares the two depths and chooses the one closer to the observer.

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 ).

Example: If the observer detected 12 meteors in 15 minutes, their hourly rate was 48.

If the time when the older observer did the experiment was t, the time of the modern experiment is t + 100 years.

If the relative velocity between an observer ( or his measuring instruments ) and the observed object is zero, then the proper length of the object can simply be determined by directly superposing a measuring rod.

If the demon were not contained within and computed by the universe, any accurate simulation of the universe would be indistinguishable from the universe to an internal observer, and the argument remains distinct from what is observable.

If the palm of the hand faces the signer ( i. e., the back of the hand faces the observer ), the sign can mean:

If the plasma ( or one ionic component of the plasma ) is flowing in the direction of the line of sight to the observer, emission lines will be seen at a different frequency due to the Doppler effect.

If that pulse is also directed towards the observer he will receive that wave information, at ' c '.

If the wave guide is moved in the same direction as the pulse the information on its position, passed to the observer as lateral emissions from the pulse, changes.

If the frame rate falls below the flicker fusion threshold for the given viewing conditions, flicker will be apparent to the observer, and movements of objects on the film will appear jerky.

If the observer looks backward ( left on the grid ), then points appear red ( redshift ) and lines appear closer together.

If he can bounce back with one of those 25 home runs years, the club will have to be better off offensively.

If a concessionaire runs the cafeteria, keep an eye out for quality and price.

If she runs around with other men, and if you hate her as you say, why not just divorce her ''??

If a player holds onto his stock, he runs the risk that the acquired chain may not reemerge before the game ends.

If no errors and no passed balls occur during the inning, all runs scored are automatically earned ( assigned responsible to the pitcher ).

If the game has been scored correctly, the total number of plate appearances for a team should equal the total of that team's runs, men left on base, and men put out.

If an implant is used, the individual runs the same risks and complications as those who use them for breast augmentation but has higher rates of capsular contracture ( tightening or hardening of the scar tissue around the implant ) and revisional surgeries.

If the compiled program can run on a computer whose CPU or operating system is different from the one on which the compiler runs, the compiler is known as a cross-compiler.

If the player either hits the ball through the correct hoop (" runs " the hoop ), or hits another ball ( a " roquet "), the turn continues.

( If one string runs out of letters to compare, then it is deemed to come first ; for example, " cart " comes before " carthorse ".

If the match duration is three or four days, the minimum lead is 150 runs.

If a rider is thrown from a horse but has a foot caught in the stirrup, they could be dragged if the horse runs away.

* If legacy software runs on only antiquated hardware, the cost of maintaining the system may eventually outweigh the cost of replacing both the software and hardware unless some form of emulation or backward compatibility allows the software to run on new hardware.

Herzog would later say of Smith's contributions that, " If he saved two runs a game on defense, which he did many a night, it seemed to me that was just as valuable to the team as a player who drove in two runs a game on offense.

If that solution runs in polynomial time, then that problem is in BQP.

The algorithm for deciding this is conceptually simple: it constructs ( the description of ) a new program t taking an argument n which ( 1 ) first executes program a on input i ( both a and i being hard-coded into the definition of t ), and ( 2 ) then returns the square of n. If a ( i ) runs forever, then t will never get to step ( 2 ), regardless of n. Then clearly, t is a function for computing squares if and only if step ( 1 ) terminates.

If it runs down the walls, it may seep into the mortar or through panels.

If the player cannot reach the needed score — or if the timer runs out — the game ends, and the player receives a final score.

If this download to the missile fails during power-up, basic functionality runs off the on-board ROM.

If a player runs out of army pieces during the game, another color may be used to substitute, or another symbolic token to help keep track of armies.

If outcomes of different runs of an experiment differ in any way that matters, they are distinct outcomes.

If intaglio methods, such as copper plates, were used for the images, then images and the text would have required separate print runs on different machines.

If however time runs out during his move, the game ends without the delay time being added.

If any portion of the waters of the Amazon runs round the southern side of the large island of Marajó into the river Para, it is only through tortuous, natural canals, which are in no sense outflow channels of the Amazon.
