But, on the other hand, there had been planted, long before, the germs of a heliocentric theory.
See Delambre on the discovery of the satellites of Jupiter as the turning-point with the heliocentric doctrine.
For the germs of heliocentric theory planted long before, see Sir G.
It would appear that Copernicus conceived the idea of the heliocentric system of the universe while he was a comparatively young man, since in the introduction to his great work, which he addressed to Pope Paul III.
It appears that in the year 1616 the church became at last aroused to the implications of the heliocentric doctrine of the universe.
First, then, it came in the form of the heliocentric theory of the planetary system.
But even Ptolemy did not conceive the heliocentric theory,--the sun the centre of our system.
But this was no heliocentric system, since the sun moved, like the earth, in a circle around the central fire.
There is no evidence that this great astronomer supported his heliocentric theory with any geometrical proof, although Plutarch maintains that he demonstrated it.
They lay down a relation between the areas described by the heliocentric radius-vector of a planet and the time employed in describing them, a relation between the longer axis of the orbit and the time taken up by the course.
It was not to be expected that Ptolemy should have adopted theheliocentric idea of Aristarchus.
We must not forget that even so great an observing astronomer as Tycho Brahe, so late as the seventeenth century, declined to accept the heliocentric theory, though admitting that all the planets except the earth revolve about the sun.
Yet, as we now see, the heliocentric doctrine, which we know to be true, had been thought out and advocated as the correct theory of celestial mechanics by at least one worker of the third century B.
As already noted, theheliocentric doctrine is not expressly stated here.
It was not to be expected that his mind would be attracted by the heliocentric theory of Aristarchus.
Here, then, was the heliocentricdoctrine reduced to a virtual demonstration by Aristarchus of Samos, somewhere about the middle of the third century B.
The picture of the universe which has thus arisen before our mind's eye is a startling one only so long as we keep comparing it with its heliocentric predecessor.
And more than that, when the heliocentric aspect is seen in its true setting, it forms (as will be shown later) an extremely revealing part of the script which tells us of the nature of the astral forces.
This raises the question of how far the Copernican, heliocentric aspect is valid in a science which strives to embrace the astral realm of the universe in its inquiries.
This statement must not be taken to deny all justification to the heliocentric view-point.
When Kepler, against the hopes of his forerunner and friend, Tycho Brahe, accepted the heliocentric standpoint and made it the basis of his observations, he did so out of his understanding of what was the truth for his own time.
When Kepler declared himself in favour of the heliocentric aspect, as indicated by Copernicus, he acknowledged that the universe had grown dumb for man's inner ear.
It is easy to see why the apparent motions of the planets were accounted for by deferents and epicycles, before the Copernican system revealed the true nature of the solar system as heliocentric and not geocentric.
An example exists connected with the heliocentric model of the Universe.
Nikolaus Copernicus published in the last year of his life the heliocentric theory of the Universe.
The heliocentric system was condemned as being opposed to Scripture and therefore heretical, and Galileo was obliged to promise never again to put it forward (1616).
Under these disadvantageous circumstances, it is scarcely surprising that the heliocentric theory, while admired as a daring speculation, won its way slowly to acceptance as a truth.
A genuine heliocentric system, developed by Aristarchus of Samos (fl.
In the system of heliocentric co-ordinates, the plane in which the earth moves round the sun, which is the plane of the ecliptic, is taken as the fundamental one.
A very potent influence is also due to the heliocentric longitude of the sun, in determining the character of any given year.
Considering this centre, therefore, as the centre of an imaginary sun, from which heliocentric longitudes are reckoned, the longitude of the real sun will vary with the positions of the great planets of the system.
The Heliocentric System was merely a new mode of representing to the mind facts, with which all astronomers had long been familiar.
The heliocentric theory of the universe, established by him with vast labour and deep knowledge, was, for the succeeding century, the field of discipline and exertion of all the most active speculative minds.
It is clear from his own statement that Copernicus learned the heliocentric doctrine from the ancients, among whom doubtless was Pythagoras, who learned it from the Egyptians, among whom he spent twenty-two years of his life.
As this furnished an illustration in miniature of the Copernican theory of the solar system, it was hailed with great delight by the ever increasing number that accepted the heliocentric doctrine.
Enough has been said to show that the false geocentric theory has been displaced by the heliocentric doctrine, which has been demonstrated to be true.
These believed in the heliocentric theory--the theory which regards the sun as the centre of our planetary system, and that the earth is comparatively a small and subordinate body revolving around it.
To these add the bog, tangent of half the angle between the planet and Sun, taken by heliocentric longitude, which call A.
Thus by the mean motions and the equation to centre the true longitudes of the planets in their heliocentric orbits are obtained.
The moveable straight lines, free at one extremity, and at the other attached to the centre of the sun, are called the Vector heliocentric radii.
The heliocentric theory of the solar system had to wait until the invention of the telescope before it could be finally established.
As a matter of fact, it has since been found that the heliocentric place of the new planet then given was correct within about 2°.
We are being asked to make considerable changes in our literary conception of the Scriptures, but not greater changes than were involved in the acceptance of the heliocentric astronomy.
For great scientific discoveries, like the heliocentric astronomy, are not merely new facts to be assimilated; they involve new ways of looking at things.
The heliocentric system, thus regarding the sun as the central orb, degraded the earth to a very subordinate rank, making her only one of a company of six revolving bodies.
Soon there was not to be found in all Europe an astronomer who had not accepted the heliocentric theory with its essential postulate, the double motion of the earth--movement of rotation on her axis, and a movement of revolution round the sun.
The conception of law which is unmistakably conveyed by Kepler's discoveries, and the evidence they gave in support of the heliocentric as against the geocentric theory, could not fail to incur the reprehension of the Roman authorities.
In the fifteenth century Nicholas of Cusa and Regiomontanus had hinted at the heliocentric theory; but 1512 marks an epoch in the history of science, since for all time Copernicus put the problem in a way that compelled acquiescence.
Nor could the new astronomy and the acceptance of the heliocentric views dislocate the popular belief.
He prints it as his motto on his books and journals, and regards it as a slow poison that will in time effect the destruction of the rabble of scientists, and reveal the truth of his own Psycho-Harmonic Science or Heliocentric Astrology.
Position of Man according to theHeliocentric and Geocentric Theories.
Sidenote: The apparent position of man on the heliocentric theory.
Against the opposition it had to encounter, the heliocentric theory made its way slowly at first.
A century before Copernicus, Cardinal de Cusa had partially adopted the heliocentric theory, as taught in the old times by Philolaus, Pythagoras, and Archimedes.
Thus we see that the heliocentric theory, as proposed by Copernicus, was undergoing rectification.
The first formal assertion of the heliocentric theory was made in a timid manner, strikingly illustrative of the expected opposition.
Andreas Osiander, he complains of the imperfections of the existing system, states that he has sought among ancient writers for a better way, and so had learned the heliocentric doctrine.
In no insignificant manner did the establishment of the heliocentric theory, aided by the discoveries of the telescope, assist in this result.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "heliocentric" in a variety of sentences. We hope that you will now be able to make sentences using this word.
