Hipparchus of Nicaea… Hipparchus of Nicaea changed the world of Math and Science for years after his final breath. Hipparchus is considered to be the father of Trigonometry, a branch of math, and to have study the orbit of the Moon and Sun determining their size and distance from Earth. Hipparchus of Nicaea is said to be one of the greatest scientist of all times. Despite his brilliancy barely anything is known about Hipparchus or his works. The information that we have on Hipparchus is second hand accounts from him many students, the work his students produced especially Almagest by Ptolemy, and the only surviving work that is still left today, Τῶν Ἀράτου καὶ Εὐδόξου φαινομένων ἐξήγησις (Commentary on the Phaenomena of Eudoxus and Aratus). …show more content…
It was in Hipparchus home city where he studied Astronomy under Theodosius. Theodosius was known for studying the sun, inventing the sundial for anywhere on the Earth, and writing the book Sphaericus. Theodosius’s ideas and mathematical equations are similar to the teachings of Hipparchus leading many to believe that Hipparchus was a student under Theodosius. Hipparchus is thought to have been born in 190 B.C, the exact day of his birth is unknown. Nothing is known about his parents or his childhood. The earliest record of his existence is in 190 B.C when he was in Bithynia composing weather patterns. Hipparchus was born during the Age of Pericles, the last remnants of the Golden Years of Greece. The Golden Years of Greece was a flourish of culture, economic growth, and Greek politics. Hipparchus being born into the later years of the Golden Years would affect him and his works later on in his life and also …show more content…
Hipparchus was a teacher to many other inspiring thinkers. Many of the information we have on Hipparchus today is from the works his students have attributed especially one of his students, Ptolemy. Hipparchus’s ideas and many of his works are written down in their own words or copied giving us a better sense of who he is and what he did. Hipparchus was not just a great scientist but a great teacher too.
The works… We have no surviving works of Hipparchus. The great works and notes of the astronomer were lost to time or destroyed unknowingly. Despite having nothing but one single work, Τῶν Ἀράτου καὶ Εὐδόξου φαινομένων ἐξήγησις (Commentary on the Phaenomena of Eudoxus and Aratus) he has contributed to science and math for many centuries past his lifetime. The Commentary on the Phaenomena of Eudoxus and Aratus is the only work left and is a calendar with references to the risings and settings of constellations.
The End… Unfortunately we know nothing about Hipparchus’s death. We have an estimated time period of disappearance from others works and his own. The sudden disappearance leads many to believe that is was either retirement or a death. Many historians believe it was a sudden death from the sudden loss of mention or works. We will never know how Hipparchus died or the reason why but his name will live on in his works and great
He is one of the first artists to begin signing his work, placing him at the transition from late archaic to early classical art in the beginning of his career. Euphronios is projected to have been born around 535 BCE, making him roughly twenty five when the death of Sarpedon krater was created. It is also believed that Euphronios began studying under Psiax, an elder vase painter, in 520 BCE. Euphronios’ work influenced his mentor and other elder vase painters. Growing in the field of art, it became apparent that Euphronios had the tendency to paint mythological scenes, everyday life, and monumental compositions.
Hipparchus was a greek astronomer, geographer, and mathematician born 190 B.C. in Nicaea and died in 120 B.C. Rhodes, Rhodes, Greece. Hipparchus is accredited as the inventor of trigonometry because of his discovery of the first table of chords and also because he's the only person with valid data of the discovery and usage of trigonometry. In order to calculate the rising and setting of zodiacal signs, Hipparchus brought to light the division of circles into 360 degrees and the calculation of chords by looking at the triangles (spherical triangles or triangles that made up a circle) differently. Hipparchus experimented putting all triangles to be within a circle and with the three points each touching the
In this time period the Greeks emperors believed and paid lot of money to have astronomers make new discoveries of the planets and stars. Astronomy was a big mixture of knowing how the planets worked and mathematics. As more and more theories began coming to picture, each of them were built off of eachother. These theories also allowed inventions to come to life, some that we even use still today such as the telescope. Even though these theories and inventions are old, they have influenced today's technologies and space science. Just how Newton's theory of gravity was influenced on other great greek astronomers and their studies.
While researching “pre-industrial astronomical accomplishments,” it seemed that a good majority of the accomplishments being highlighted were those of the Mayan and Aztec civilizations. Feeling that these topics may be over-researched, I decided to turn my attention towards the accomplishments of those in a different area of the world. After switching my focus to the pre-industrial astronomical feats of ancient Greek scientists, I have found that in many cases, these scientists contributed more than one idea, finding, or apparatus to the field of astronomy. For this research, I decided to hone in on the contributions made by Greek scientist Hipparchus. Throughout his magnificent life, and all before the implementation of modern technology,
There were many contributions during this period. Copernicus published “On the Revolution of the Heavenly Spheres” which was based on mathematical calculations that led him to the theory that everything moved around the Sun, not the Earth as was thought. Kepler, a mathematician, published supporting evidence of the heliocentric theory that Copernicus had written about. Both challenged what was thought to be the model of the Universe since Aristotle. Galileo added to the by perfecting a telescope that could see far into the heavens and revealed new worlds. While Newton, an astronomer and mathematician wrote Principia, which explained the laws of motion and the law of universal gravitation using the inductive and deductive reasoning. This
Empedocles, an ancient Greek philosopher from Arcagas a southern Greek colony in Sicily, was not only a philosopher; he was a poet, a physician, a politic, and a scientist. Empedocles was born into a wealthy aristocratic family with prestigious recognitions. His grandfather who he was named after, Empedocles, was said to be a victor in horseracing at the 496 B.C.E. Olympic Games.
As of now, Greek social impact and force was grinding away's top in Europe , Africa and Asia, encountering success and advance in human expressions, investigation, writing theater, building design, music, science, rationality, and science. It is frequently viewed as a time of move, at times even of wantonness or degeneration,[ contrasted with the splendor of the Greek Classical period. The Hellenistic period saw the ascent of New Comedy, Alexandrian verse, the Septuagint and the theories of Stoicism and Epicureanism. Greek Science was progressed by the works of the mathematician Euclid, the space expert Ptolemy and the doctor Galen. The religious circle extended to incorporate new divine beings, for example, the Greco-Egyptian Serapis, eastern gods, for example, Attis and Cybele and the Greek appropriation of Buddhism. After Alexander the Great's endeavors in the Persian Empire, Hellenistic kingdoms were built all through south-west Asia Seleucid Empire, Kingdom of Pergamon , north-east Africa Ptolemaic Kingdom and South Asia Greco-Bactrian Kingdom, Indo-Greek Kingdom.
The Greeks made several inventions, most notably in the subject of math, which are still studied today and taught in school. Mathematician Euclid is often credited as the “Father of Geometry” for all his work and studies in this subject, which are compiled in his books called The Elements. He organized known geometrical statements called theorems and logically proved all of them. He proved the theorem of Pythagoras (another Greek mathematician), which stated that the equation (c2 = a2 + b2) is true for every right triangle.
Miletus was also a great cultural center and produced many great citizens with different and new innovations that helped both Ionia and Greece. Thales of Miletus was one of the wisest men of the ancient times. He is seen as the father of Pre-Socratic Greek philosophy. He applied his knowledge of the natural causes of the world and originated the science of metaphysics. Thales will be followed by other great thinkers like the philosophers Anaximander, who learned from Thales, and Anaximenes, who was a student of Anaximander. They also had influence in the other humanities like the historian Hecataeus who was interested in geography, and the poet Phocylides who was known for his honest words, and the famous city-planner
Empedocles was a pre-Socratic philosopher who lived from 490 to 430 BC in Acragas, Sicily, Italy. His writings mainly focus on the study of cosmetology, religion, and nature; and have influenced some of today’s modern theories in science. Although he was a colorful character who claimed to be able to bring back the dead, he maintained a democratic political standpoint and was known for being generous and fought for equality of the people. Empedocles was a poet, philosopher, and physician.
He was the first person whose systematic use of trigonometry has documentary evidence, which is presented from Ptolemy and Theon of Alexandria. For example, he is responsible for the division of a circle into 360 degrees, the creation of one of the first trigonometric tables for solving triangles, and the precepts of trigonometry. The table showed how each degree divided into 60 minutes, which made the radius 360.60/2π = 3438 minutes and the chord function Crd of Hipparchus is related to the sine function by (Crd 2a)/2 = 3438 sin a. The table of chords, explained in 12 books, is used as a method to solve triangles without having to solve each triangle from first principles. As an astronomer, he calculated the length of the year to within 6.5 minutes. He also discovered the precession of equinoxes with a value of 46 degrees, which is fairly close to the modern number of 50.26 degrees. The precession of the equinoxes, or the gradual shift in Earth’s rotation axis, demonstrates how the earth wobbles like a top as it spins, which indicates there is a shift in point of direction of the poles over time. Hipparchus’s calculations are able to explain why the north star changes throughout a 26,000-year cycle; at some point of time it was Thuban, Beta Ursae Majoris, and the Polaris star is the north star now. In addition, he charted the sky with 850 stars and motions of the moon. These are
Aristotle was one of the many great thinkers among him he made the geocentric theory which later led to Pythagoras adding to Aristotle’s theory. Several years later Nicolaus Copernicus contested Aristotle theory; arguing that the heliocentric theory was correct. Johannes Kepler later on used mathematical laws to prove
Archimedes was one of the most known and respected mathematicians of ancient Greece. He was born between the years of 290 and 280 BCE in Syracuse, Sicily which is currently known as Italy. His death took place in Syracuse, Sicily between the years of 212 and 211 BCE. In autumn of 212 or the spring of 211 Syracuse was taken over by Roman General Marcus Claudius Marcellus (Encyclopedia Britannica, n.d). It was during the cities take over that Archimedes was killed. There is rumors about what lead up to a Roman solider killing him. Some historians believe his death was due to Archimedes not willing to give up his mathematical diagrams of mirrors that would burn the Roman ships. The exact years of his birth
Discuss the presentation of Phaedra and nurse in Hippolytus. How sympathetically does Euripides present these characters?
Socrates is known in todays world as one of the greatest philosophers in history. He brought many revolutionary ideas to ancient Athens during his life and even after his death. He had many followers that beloved him even till death. His tragic death only led him to become a martyr for philosophy. Socrates never wrote anything down so what we know of his life is the from the records left by his followers, mainly Plato.
