If his dancers are sometimes made to look as if they might be creatures from Mars, this is consistent with his intention of placing them in the orbit of another world, a world in which they are freed of their pedestrian identities.

If there are other stars orbiting a black hole, their orbit can be used to determine its mass and location.

If F ( r ) represents gravity, it is a negative term proportional to 1 / r < sup > 2 </ sup >, so the net acceleration in r in the rotating frame depends on a difference of reciprocal square and reciprocal cube terms, which are in balance in a circular orbit but otherwise typically not.

If the next time the orbit loops around phase space in a different way, then it is impossible to rectify the vector field in the whole series of patches.

McVeigh argued that " imminent " does not mean " immediate ": " If a comet is hurtling toward the earth, and it's out past the orbit of Pluto, it's not an immediate threat to Earth, but it is an imminent threat.

If the initial firing is above the surface of the Earth as shown, there will also be elliptical orbits at slower velocities ; these will come closest to the Earth at the point half an orbit beyond, and directly opposite, the firing point.

If the heavier body is much more massive than the smaller, as for a satellite or small moon orbiting a planet or for the Earth orbiting the Sun, it is accurate and convenient to describe the motion in a coordinate system that is centered on the heavier body, and we say that the lighter body is in orbit around the heavier.

If the interceptors were placed in orbit, some of them could be positioned over the Soviet Union at all times.

If " hot Jupiters " did exist in close orbit they would likely disrupt the star's habitable zone ; their exclusion is thus a positive for the possibility of Earth-like planets.

If a photon rocket begins its journey in low earth orbit, then one year of thrusting may be required to achieve an earth escape velocity of 11. 2 km / s if the vehicle is already in orbit at a velocity of 9, 100 m / s, and 400 m / s additional velocity is obtained from the east to west rotation of the earth.

If the axis of the rotation lies external of the body in question then the body is said to orbit.

If one could see a satellite in geostationary orbit, it would appear to hover at the same point in the sky, i. e., not exhibit diurnal motion, while the Sun, Moon, and stars would traverse the heavens behind it.

If its density is similar to Amalthea's, Metis's orbit lies within the fluid Roche limit ; however, since it has not broken up, it must lie outside its rigid Roche limit.

If an instantaneous centripetal force ( red arrow ) is considered on the planet during its orbit, the area of the triangles defined by the path of the planet will be the same.

If a binary star happens to orbit in a plane along our line of sight, its components will eclipse and transit each other ; these pairs are called eclipsing binaries, or, as they are detected by their changes in brightness during eclipses and transits, photometric binaries.

If the motion is part of an orbit, or if the stars have similar radial velocities and the difference in their proper motions is small compared to their common proper motion, the pair is probably physical.

If the relative motion of a pair determines a curved arc of an orbit, or if the relative motion is small compared to the common proper motion of both stars, it may be concluded that the pair is in mutual orbit as a binary star.

If the motion is part of an orbit, or if the stars have similar radial velocities or the difference in their proper motions is small compared to their common proper motion, the pair is probably physical.

If the circumstances are faced frankly it is not reasonable to expect this to be true.

If a work is divided into several large segments, a last-minute drawing of random numbers may determine the order of the segments for any particular performance.

If they avoid the use of the pungent, outlawed four-letter word it is because it is taboo ; ;

If Wilhelm Reich is the Moses who has led them out of the Egypt of sexual slavery, Dylan Thomas is the poet who offers them the Dionysian dialectic of justification for their indulgence in liquor, marijuana, sex, and jazz.

If he is the child of nothingness, if he is the predestined victim of an age of atomic wars, then he will consult only his own organic needs and go beyond good and evil.

If it is an honest feeling, then why should she not yield to it??

If he thus achieves a lyrical, dreamlike, drugged intensity, he pays the price for his indulgence by producing work -- Allen Ginsberg's `` Howl '' is a striking example of this tendency -- that is disoriented, Dionysian but without depth and without Apollonian control.

If love reflects the nature of man, as Ortega Y Gasset believes, if the person in love betrays decisively what he is by his behavior in love, then the writers of the beat generation are creating a new literary genre.

If he is good, he may not be legal ; ;

If the man on the sidewalk is surprised at this question, it has served as an exclamation.

If the existent form is to be retained new factors that reinforce it must be introduced into the situation.

If we remove ourselves for a moment from our time and our infatuation with mental disease, isn't there something absurd about a hero in a novel who is defeated by his infantile neurosis??

If many of the characters in contemporary novels appear to be the bloodless relations of characters in a case history it is because the novelist is often forgetful today that those things that we call character manifest themselves in surface behavior, that the ego is still the executive agency of personality, and that all we know of personality must be discerned through the ego.

If he is a traditionalist, he is an eclectic traditionalist.

If our sincerity is granted, and it is granted, the discrepancy can only be explained by the fact that we have come to believe hearsay and legend about ourselves in preference to an understanding gained by earnest self-examination.

If to be innocent is to be helpless, then I had been -- as are we all -- helpless at the start.

If, when this was all over, she found the words to tell him about it, she wondered if he would ever understand.

If the old fool argues about the price, tell him I shall order my husband not to treat him as a patient any longer.

If I am to speak the whole truth about my knowledge of love, I will have to stop trying to emulate the transcendant nightingale.

If art is to release us from these postulated things ( things we must think symbolically about ) and bring us back to the ineffable beauty and richness of the aesthetic component of reality in its immediacy, it must sever its connection with these common sense entities ''.

If one follows the reports of the Congress, one finds that there still seems considerable uncertainty in the minds of the leaders themselves about what exactly to do in this matter.

If we go into this Common Market, we might just as well stop talking about Constitutional guarantees, Connally Amendments or, for that matter, conservatism in general.

If and when Hino decided to tell him about his experiences, he would do so unasked.

If doubtful about a steak, boldly cut it in half.

If such is the case, the particles within a distance of about Af of the Earth will have, relative to the Earth, a kinetic energy less than their potential energy and they will be captured into orbits about the Earth.

If the vertex is at Af, and if the interior of C is on the left as one moves in the direction of increasing t, then every such corner can be found from the curve obtained by rotating C clockwise through 90-degrees about the vertex.
