Plane rotation necessarily involves the orbital diversion of every particle in the cube.
This alone is sufficient to prohibit such a rotation; for it is obvious that the moment a particle or any series of particles is diverted from its established orbital path disruption of that portion of the cube must necessarily follow.
Nearer and nearer to Earth the freighter swept, completely encircling the planet like a runaway moon with an orbital velocity so great the eye could hardly follow it.
Maneuvering into an orbital position almost directly abreast of the Station had been difficult.
They quoted reams of statistics: height above the center of the Earth in kilometers, orbital velocity, relation of mass to maneuverability.
The smile he turned on Burris was as cold and empty as the inside of Orbital Station One.
Remember how everybody used to laugh about spaceships, and orbital satellites, and life on other planets?
We have orbital satellites, and we've landed on the Moon with an atomic rocket.
The movements of rotation of the sun, of the planets, and the satellites, are in the same direction as their orbital motions, and in planes little different.
As already pointed out, another phenomenon which can be physically accounted for by the sun's orbital motion through space around its central body, is that celestial plane known as the Plane of the Ecliptic.
This is proved by the fact that Mercury has a greater orbital velocity than Venus, Venus than the Earth, the Earth than Mars, and so on right through the whole of the planetary system.
Herschel first attacked the question as to whether the sun, like all the other stars, was in motion, and if in motion, what was the shape of its orbit, and the laws which governed its orbital velocity.
Kepler by his Third Law showed that the chief regulating factor in the orbital velocity of a planet was its mean distance from the sun.
It would, therefore, be unphilosophical to revert to the old conception of a gravitating attractive power as the sole cause of the sun's orbital motion through space.
The near future will hold such wonders as the orbital flight of an astronaut, the landing of instruments on the moon, the launching of the powerful giant Saturn rocket vehicles, and the reconnaissance of Mars and Venus by unmanned vehicles.
Nonetheless, the first manned orbital flight is now scheduled for March, 1981.
In making this estimation, the water is supposed to stand on a level with the orbital plate of the frontal, with the deepest notch in the squamous margin of the parietal, and with the superior semicircular ridges of the occipital.
Circumference over theorbital ridges and the superior semicircular lines of the occipital.
Tenderness at the point of exit of the left supra-orbital nerve.
Thus the eyes are usually closed and sealed by the swollen lids and the orbital depressions are effaced.
But how do we get the orbital speeds to help us, Major?
And the other is to take advantage of Tara's orbital speed around its sun Alpha Centauri, and Junior's orbital speed around Tara.
The escape time, combining orbital speeds of Tara and Junior, are completed, and we have six hours and fifty-five minutes before blast-off!
If we fail, it'll be more than a year before Junior will be in the same orbital position again.
The external orbital apophysis (formed from the frontal bone).
The forehead is very low and receding and the orbital arches are enormously developed; while the cerebral capacity calculated from the cranial dimensions is inferior to that of modern man.
The minimum frontal point (a bony angle which may be felt about 1 centimetre above the external orbital apophysis, along the temporal line).
The female cranium in fact has a straighter forehead than the male and the orbital arches are absolutely wanting, while the entire surface of the cranium is smoother and more rounded.
The horizontal branch is placed tangent to the vertex, its direction should be perceptibly parallel to the transverse orbital line, the graduated vertical branch should pass over the auricular foramen.
The maximum frontal diameter: between the two external orbital apophyses.
Whether they are there by constant projection, and fall again to the sun, or are held by electric influence, or by force of orbital revolution, we do not know.
It is also asserted that the newly discovered planet Vulcan makes an orbitalin less time than the sun makes an axial revolution.
On the 16th it was seen again, and its orbitalmotion followed.
Obviously it must make just one axial to one orbital revolution.
The times of orbital revolution of Saturn and Jupiter are nearly as five to two.
The direction of orbital and axial revolution seen from above the North Pole would be opposite to that of the hands of a watch.
The orbital velocity of the various planets in miles per second is as follows: Mercury 29.
The speed of thisorbital revolution must be proportioned to the distance from the sun.
Subsequent measures, of far greater precision than those obtainable by other methods in the case of easily separated double stars, show the rapid orbital motion of the components of the system.
During the three months’ stay of the patient in the eye department, once more swelling of the left orbital region and air under the conjunctiva of the left globus oculi suddenly appeared one day, but disappeared over night.
It was the skin swelling of the orbital region that had given rise to the diagnosis of Quincke’s disease.
The supra-orbital points were sensitive to pressure.
The last group of sequences includes orbital precessions, seasonal alternations, and daily variations.
Other investigations show numerous remarkable coincidences between sunspots and the orbital revolution of the other planets, including especially Saturn and Mercury.
A study of sunspots suggests that their true periodicity is almost if not exactly identical with that of the orbitalrevolution of Jupiter, 11.
The gist of the hypothesis has already been given in connection with the type of climatic sequence known as orbital precessions.
Between glacial fluctuations and historical pulsations in duration, but probably less severe than either, comeorbital precessions.
Bleeding from the nose and mouth is not uncommon in fatal scurvy, and occasionally exophthalmos is present, usually unilateral, and due to subperiosteal hemorrhage of the orbital plate of the frontal bone.
Community of drift" is visible in many distinct sets; while there is as yet no perceptible evidence, fromorbital motion, of association into subordinate systems.
This one mobile member of the naked eye group is Electra; and it is noticeable that the apparent direction of its displacement favors the hypothesis of leisurely orbital circulation round the leading star.
The bolide's made four orbital turns, coming in all the while.
If we assume it was a satellite that had already made several orbital turns, we must admit it would be an impossible shift in apogee for it to come down at the angle it did!
The scope of the planetary orbital path is thus rigidly determined by the planetary energy properties.
Other natural operations, such as theorbital movements of planetary masses, (Sec.
As the planet recedes from the primary it gains energy of position, but this gain is obtained solely at the expense, and by the direct transformation of its own orbital energy of motion.
In any given case it is obvious that this limiting displacement must be a finite quantity, since the planetary orbital energy which is being worked down is itself finite in amount.
But since this orbital energy is strictly limited in amount, a point must ultimately be reached where it would be transformed in its entirety into energy of position.
Limit of Gravitation Transformation In the case of a planetary body, there is a real limit to the extent of the transformation of its orbital energy of motion under the influence of the gravitation field.
It is to be noted, however, that although they have a common origin the orbital energy of each planetary mass is entirely distinct from its energy of axial rotation, and is not interchangeable therewith.
In this limiting condition, also, the energy of position of the planet would be the maximum possible, and its orbital energy zero.
The temporal arcades were quite developed, with prominent supra-orbital bosses.
Eyes wide apart and widely expanded, so that the entire circle of the iris was exposed, although the eyeball itself was not à fleur de tête, but rather sunk into excessively spacious orbital cavities in the skull.
The geological age plays the same part in our views of the duration of the universe as the Earth's orbital radius does in our views of the immensity of space.
Thus, wholly or in part, the activity of organisms is recurrently affected by the great energy--tides set up by the Earth's orbital motion.
