ARISTARHUS of SAMOS: & HIS HELIOCENTRIC SYSTEMARISTARHUS was certainly both a mathematician and astronomer and he is most celebrated as the first to propose a sun-centred universe. He is also famed for his pioneering attempt to determine the sizes and distances of the sun and moon.There was a time when people thought that the earth was the center of the universe. Although Nicolaus Copernicus and Galileo Galilei got credit for this idea in the 1500’s, this theory was ACTUALY originated by the ANCIENT GREEK ASTRONOMER and MATHEMATICIAN known as ARISTARHUS of SAMOS. HERE`s MORE information about WHO was and his CONTRIBUTION to ASTRONOMY:Early Life of AristarchusAristarchus of Samos was born approximate 310 B.C in an area known as Samos, Greece. There are historical records that show his formal education took place in Alexandria. He eventually became head of the Greek educational system at Lyceum in Greece.Sun is at the CenterAristarchus is known for his revolutionary astronomical hypothesis. It was Aristarchus who initially put forth a theory of the Sun and not the Earth being the fixed center of the universe. It was his belief the earth and the other planets actually moved around the sun. Aristarchus also provided a theory on stars being distant suns. He claimed they did not move, and the universe was much larger than others could imagine.Inspired by Philolaus of CrotonAristarchus of Samos was inspired by the work of Philolaus of Croton, who put forth the idea that the cosmos existed because unlimited fire is found at the center of a cosmic sphere. This is the first person recognized as placing the other planets in their correct order as well as correct distance from the sun.Development of HypothesisThe written book “On the Sizes and Distances of the Sun and Moon” is the only known work that Aristarchus wrote. When he had completed this, Aristarchus felt presenting it would have not have benefited him since it was a contradiction to the general consensus of the Greek scientific community. His book was based on the observations made during a lunar eclipse. He determined the Earth’s shadow was twice the diameter of the Moon’s shadow. Aristarchus did record the Sun and Moon being two degrees when measured for an angular diameter. He was also able to show the angular distance between the Moon and sun during the time of quarter moon as 87 degrees.Implications of this TheoryMany modern scientists believe the hypothesis put forth by Aristarchus had other interesting aspects to it beyond all the planets in the universe rotating around the sun. With the use of geometry, he determined the Sun may be as much as 20 times farther away from the earth than the moon. His figures were not as accurate as such calculations would be by future astronomers. Aristarchus did use a sound geometric method for his calculations. This was the correct way to make such a determination. It was using this method that made more sophisticated and accurate celestial calculations possible.Aristarchus of Samos died in circa 230 B.C. He is recognized by most astronomers as someone who was advanced in his thinking and ideas for the time when he lived. Aristarchus of Samos did not get much recognition during his life for his work but he did achieve credit later on.The GREEKS SHOULD NEVER LEARN that: DEMOCRITUS , PYTHAGORAS, HERACLEITOS completely formulated the theory of NUCLEAR PHYSICS and SPECIAL RELATIVITY, unifying into single MATHEMATICAL(, formulas, as ELECTRICITY, GRAVITY, MAGNETISM, ASTRONOMY, and the Weak Currents of NUCLEAR ATOMS.The Greeks MUST NEVER LEARN that: the ASTRONOMERS – MATHEMATICIANS: EUDOXUS, CALLIPOS , ARISTARCHOS, ANAXIMANDROS, EUKLIDES, ARCHIMEDES, CONON, HIPPARCHUS, CLEOMEDES, APOLLONIOS, PTOLEMY, THEON, HYPATIA, PAPPUS, had EXHAUSTED the LIMITS of human INTELLIGENCE by solving MENTALY WITHOUT GRAPHICAL REPRESENTATION equations of 12 unknowns (twelve equations twelve unknowns) while the limit of today’s computers is “7 equations 7 unknowns”.

He and his students successfully treated orthopedic, cardiac and basic surgery cases. HIPPOCRATES even performed operations on the human skull, as we read in several of his works… In addition to the operation itself, HIPPOCRATES attached great importance to the preparation of the patient and the operating room.In the work Kat’iatreion, he describes in detail how the patient should be prepared before the operation, how the tools are sterilized, how the space is shaped, but also how artificial and natural light is used during the operation…American archaeobotanists were able for the first time to study and analyze the contents of pills made by doctors in ancient Greece and which were discovered 20 years ago, in a Greek shipwreck off the coast of Tuscany…DNA analyzes showed that each pill was a mixture of at least ten different plant extracts, including hibiscus and celery. “For the first time, we now have physical evidence of what is contained in the writings of the ancient Greek physicians DIOSCORIDIS and GALENOS,” said ALLEN TWOWAY of the SMITHSONIAN INSTITUTION’s NATIONAL Museum of NATURAL HISTORY in WASHINGTON , according to New Scientist..Apostle ORPHEUS” ETYMOLOGY OF the NAME ROOT:ÁRISTOS ARKHḖ / ÁRKHŌ > ARÍSTARKHOSNATIVE NAME ROOT: GREEKÁRISTOS (ἌΡῘΣΤΟΣ) ARKHḖ (Ᾰ̓ΡΧΉ) ÁRKHŌ (ἌΡΧΩ) ARÍSTARKHOS (ἈΡΊΣΤΑΡΧΟΣ)MEANING: This name derives from the Ancient Greek name “Arístarkhos (Ἀρίσταρχος)”, composed of two elements: “áristos (ἄρῐστος)” (best, better, excellent, first-rate, thorough) plus “arkhḗ (ᾰ̓ρχή) árkhō (ἄρχω)” (beginning, origin, sovereignty, dominion, authority). In turn the name means “the perfect source, the right origin”. 1) Aristarchus of Samos (~310–230 BC) was an ancient Greek astronomer and mathematician who presented the first known model that placed the Sun at the center of the known universe with the Earth revolving around it. 2) Aristarchus of Samothrace (~220–143 BC) was a grammarian noted as the most influential of all scholars of Homeric poetry. He was the librarian of the library of Alexandria..

Aristarchus of SAMOS: The Greek thatThey “Forgot” to Mention as the Father of the Heliocentric Model.

His ideas on Astronomy were not initially accepted and considered inferior to those of Aristotle and Ptolemy, until they were successfully revived and developed by Copernicus some 2000 years later.


However, we know from various references that Aristarchus had written another book in which he proposed the alternative hypothesis of the heliocentric model.

“Cleanthis, [a contemporary of Aristarchus] believed that it was the duty of the Greeks to condemn Aristarchus of Samia on the charge of setting in motion the hearth [center] of the Universe [i.e. the Earth] and thus disturbs the tranquility of the gods: “As you move the hearth of the world and disturb the tranquility of the Olympians (gods)” …, you assumed that the sky remains stationary and the Earth turns on an inclined circle, while at the same time revolving around from its axis.”

Size of the Moon distance and size of the Sun

He found that the Moon and the Sun are almost the same apparent size from Earth and concluded that their diameters would be proportional to their distance from Earth.

The rebirth of Aristarchus theory

Stobaeus in his collection “On Physics” writes: “Aristarchus ton Helion istisisi”.

Plutarch in his work “On the likes of the Philosophers” states:

“Aristarchus placed the Sun behind the plains, and the Earth moves around the solar circle, and the Earth evolves according to an oblique circle, if it is also rotated around its axis, and during these inclinations it shadows the disc”.

The only work of Aristarchus that has survived to this day, “On the sizes and distances of the Sun and the Moon” (On the sizes and distances of the Sun and the Moon), is based on a geocentric model.

Archimedes wrote: “King Gelon, you know that the world is the name that most astronomers give to a sphere, in the center of which is the Earth, and that the radius of this sphere is equal to the distance between the Sun and and the Earth. This is the explanation given by astronomers. But Aristarchus wrote a book, which contains certain propositions, from which it is concluded that the real world is much larger.

It is believed that the flat stars and the Sun are stationary, that the Earth moves around the Sun in a circular orbit, with the Sun at its center. Even though the sphere of the plain stars, which is at the same center as the Sun, is so large that the circle around which the Earth revolves is as far from the plain stars as the center of a sphere is from the surface of … Aristarchus means the following: since we believe that the Earth is, let’s say, the center of the world, the relationship of the Earth to what we call “the world” is equal to the relationship of the sphere, which contains the circle on which the Earth is said to revolve, towards the sphere of the plain stars.”

Hence, Aristarchus believed that the stars are infinitely distant, and he considered this to be the explanation for the absence of visible parallax, that is, the observed motion of the stars as the Earth moves around the Sun. In fact the stars are much further away than was assumed in ancient times, which explains the fact that stellar parallax is detectable only with telescopes. But it had been assumed that the geocentric model was a simpler and better explanation for the lack of parallax.

The rejection of the heliocentric view was apparently quite strong, as indicated by the following text of Plutarch (On the apparent face of the circle of the moon):

Aristarchus observed the movement of the Moon through the Earth’s shadow during a lunar eclipse. He estimated that the diameter of the Earth was 3 times the diameter of the Moon.

Using Eratosthenes’ calculation that the circumference of the Earth was 42,000 km, he deduced that the Moon has a circumference equal to 14,000 km. Today, the Moon is known to have a circumference approximately equal to 10,916 km.
of the last quarter of the Moon. He estimated the angle to be 87°.
Aristarchus observed/argued that the Sun, Moon and Earth form almost a right angle at the time of the first or last quarter of the Moon. He estimated the angle to be 87°.

Using correct Geometry, but incorrect observational evidence, Aristarchus concluded that the Sun was 20 times further away than the Moon. In reality the Sun is about 390 times further away.

So he concluded that the Sun was 20 times the diameter of the Moon, which is computationally logical and correct, but also wrong (since it is based on wrong data). But this estimate of his indicates that the Sun is clearly larger than the Earth, which supports the heliocentric model.

Aristarchus was the first to propose the currently accepted heliocentric theory and founded Astronomy on logical thought, a view which, unfortunately, a portion of the international astronomical community, either justified by ignorance or even unjustifiably, does not seem to share at all. Unfortunately for the heliocentric theory, ardent supporters of the geocentric theory, also introduced by Samius Pythagoras, were scientists of the stature of an Aristotle, a Hipparchus or a Ptolemy… Consequently, the revolutionary idea of Aristarchus could not be accepted.

It fell into oblivion without being completely forgotten until the Renaissance, when in 1543, about two millennia later, it was vindicated by the famous Polish astronomer Nicolaus Copernicus. Although Copernicus simply brought the heliocentric theory out of obscurity, thus repeating the ideas of Aristarchus, he is nevertheless regarded today as the proponent of the heliocentric theory, and the currently accepted heliocentric system is still internationally called “Copernicus” and not “Aristarchian”. , as it should be.

The survival of the heliocentric theory, despite the polemics of its opponents, is due less to Copernicus and more to the overwhelming proofs of its correctness, given from time to time by Galileo, Kepler, Newton et al. So, the question whether the work of Copernicus is original and what is its value arises easily.

In order to give a responsible answer to this question, one should take into account the difficulties of the age of Copernicus, during which the doctrines of Aristotle prevailed, with which no one was allowed to disagree. In addition, criticism of the Polish astronomer’s theories began immediately and was particularly intense.

Although Copernicus’s contribution to the revival of the heliocentric theory is important, this is not enough for him to be recognized as the author of this theory. It is true that Copernicus knew the views of Aristarchus. This is attested by a surviving manuscript fragment of his treatise De Revolutionibus Orbium Coelestium. In it, the paragraph referred to in Aristarchus’s treatise appears to have been deleted and which, paradoxically, was not included in the printed version of his treatise presented in 1543. The fact of the deletion is characterized by some as plagiarism, while others consider the omission of reference to Aristarchus also in his theory as lack of courage or cowardice.

However, it should be emphasized that it is not absolutely certain whether the erasure should be attributed to Copernicus himself or to his editor, given that the treatise was published after his death. It is also noteworthy that the Polish astronomer did not give his consent for the publication of his treatise for a whole decade, fearing the condemnation of the Roman Catholic Church.

Finally, in 1543, a copy of his manuscript was published in Nuremberg, which was condemned in 1616 by the Church of Rome.

Copernicus is therefore not the introducer but simply the man who brought out of oblivion and spread the heliocentric theory, the authorship of which belongs exclusively to Aristarchus. Copernicus’ contribution lies mainly in the fact that he introduced the geometric mechanism of Ptolemy’s geocentric system into the heliocentric system of Aristarchus. But it is evident that, since the real difficulty, namely, the belief that the planets move smoothly in circular orbits, could not be overcome, his whole effort was on the wrong track

For the restoration of the truth but also for reasons of historical self-awareness, the widest possible information is required on the work of the great Greek astronomer Aristarchus, as one of the leading figures in the world of Greek astronomers, mathematicians and philosophers of antiquity.

Archimedes in his mathematical treatise “Psammitis” writes: “Aristarchus the Samian is supposed to be because the plains of the stars and Alion remain motionless, while Gan revolves around Alion in a circular circumference, which is in the middle of the road text”.
