Eratosthenes Eratosthenes was born in Cyrene which is now in Libya in North Africa. His teachers included the scholar Lysanias of Cyrene and the philosopher Ariston of Chios who had studied under Zeno, the founder of the Stoic school of philosophy. Eratosthenes also studied under the poet and scholar Callimachus who had also been born in Cyrene. Eratosthenes then spent some years studying in Athens. The library at Alexandria was planned by Ptolemy I Soter and the project came to fruition under
Eratosthenes Overview This paper will tell you about the life of Eratosthenes; his life, death and everything that we know in between. He was a very diverse, multitalented thinker who was also known as the “father of geography” (Fashchuk 1). The Life of Eratosthenes Eratosthenes was born in 276 B.C. in Cyrene, Libya which is present day Shahhat, Libya on the northern coast of Africa. He died in 194 B.C. at about 82 years old in Alexandria, Egypt, which is the second largest city in Egypt (Trubin)
lived in his household, including his wife, children, and slaves. Since the society greatly stressed masculinity, this was also central to the oikos as well. Adultery’s threat to Athenian society is represented in Lysias’s speech, On the Murder of Eratosthenes. Adultery was seen as a social rather than a personal issue and a more atrocious crime than rape because it demasculinized men and
In Ancient Athens, marriage and the relationship between husband and wife formed the core structure of Greek society. In both Xenophon 's Oeconomicus and Lysias ' On the Murder of Eratosthenes, there is a profound emphasis on the separation of women from men and their role in maintaining an orderly household. Both also establish unambiguous and separate spheres of responsibilities for men and women. However, there exists a clear difference between equality of the relationships and communication between
because they gave a start of information that other civilizations can build from today. Many influences of those topics were created by Aristarchus, Eratosthenes, Euclid, and Archimedes. Aristarchus was an astronomer that calculated the sun to be 300 times larger than Earth. He also suggested that Earth and the other planets revolved around the sun. Eratosthenes was the director of the Alexandrian Library, and tried calculating the size of Earth. Although the United States la...
Athens and Sparta are both infamous Greek city states. Both could not be more different, yet similar in the way they governed their own city state. Another, main difference was the women’s rights and roles in the system. Athenian and Spartan women both were considered to be second to their male counterparts. Spartan women had more rights than Athenian women. Through, research realizing that the Spartan women were slightly greater role than Athenian women. In their youth, Spartan women were allowed
today. Pythagoras, a mathematician, proved "the relationship between the legs and the hypotenuse of a right triangle."1 From this, he derived the Pythagorean Theorem. This contribution mainly influenced architecture and geometry today. Equally, Eratosthenes also influenced architecture and geometry. He developed a method of determining the circumference of the Earth by using geometry. Developed by Archimedes, the Archimedes Principle contributes greatly to the field of science. The principle states
Astronomy is a natural science focusing on the study of celestial objects such as moons, stars, planets, nebulae and galaxies. Astronomy is considered to be one of the oldest natural sciences; early civilizations throughout history such as the Babylonians, Egyptians and Greeks performed methodical observations of the sky. The Babylonians had different astronomical records regarding the position of the moon, sun and stars, on the other hand the Egyptians used astronomy to know the time and afterwards
false suppositions of unchangeable facts. For example, it was widely accepted that the earth was flat until Eratosthenes proved it false. We could here say: Eratosthenes rendered it false that the earth was flat. He clearly did not cause the earth to be not flat, nor did he cause the true proposition of the earth being flat to be false. The earth had always been not flat in spite of Eratosthenes’ discovery. It simply means that he proved the falsity of a proposition that was falsely assumed all along
How can we find a large prime number People use numbers whenever they do math. Yet, do they know that each number in the number system has its own unique trait? Numbers such as 4 and 9 are considered square numbers because 2 times 2 is 4, and 3 times 3 is 9. There also prime numbers. Prime numbers are numbers that have exactly two divisors. The number one is not included because it only has one divisor, itself. The smallest prime number is two, then three, then five, and so on. This list goes
Alexander is considered one of the greatest leaders of all time. He was tutored by Aristotle, A student of Plato who was a student of Socrates. Alexander discovered the Phalanx that was once undefeated and took land from Macedonia to the coastline of India. Alexander’s mother was Olympia and his father was Philip the second of Macedonia. Philip ii was Macedonia's commander in chief and led them to many battles. Philip the second of Macedonia was held hostage for several years until his brother (at
The Age of Alexander The conquests of Alexander the Great spread Hellenism immediately over the Middle East and far into Asia. After his death in 323 B.C., the influence of Greek civilization continued to expand over the Mediterranean world and W Asia. The wars of the Diadochi marked, it is true, the breakup of Alexander's brief empire, but the establishment of Macedonian dynasties in Egypt, Syria, and Persia (the Ptolemies and the Seleucidae) helped to mold the world of that day into a wider
during this period. Unfortunately, the Library of Alexandria was destroyed centuries later during one of mankind’s numerous conflicts, and much of the information stored within it was lost to time. However, many scientific advances survived, such as Eratosthenes’ surprisingly accurate calculation of the Earth’s circumference and tilt of its axis, or the many works of Archimedes, who is especially well known for calculating
It's important to know that he was tutored by the great minds of the day because this shows that he was influenced by well known scholars such as the great astronomers conon and eratosthenes. Archimedes inventions show just how much of a genius he really was but some of what he did has been extremely exaggerated, "Of the many exaggerated tales of his skill one mentions a giant mirror that he used to set enemy ships on fire. Another
As Juan Ramón Jiménez once said, “If they give you ruled paper, write the other way.” Individuality is not only how one presents oneself and the activities one may prefer to partake in, but also the questions they ask about the world. Without Eratosthenes’ and Copernicus’ doubts, many quirks about our planet would be left undiscovered. They went against what was told as ‘truth’, and questions led them to what was right. If J. J. Thompson had not experimented, no one would even know what they were
In the city-state of Athens around fifth century BCE, men and women worked around the clock, making sure that their oikos (household) reflected exceptionally upon the polis (city-state). Citizens were the only people who had full control over the household, while everyone else who was not a citizen lacked and/or lucked out on many of the privileges. Being a citizen came with many entitlements, but it also brought a great deal of responsibility with it as well. Running a highly respect oikos required
Greek legacies are their governmental systems, culture and arts, and science and technology. Classical Greece was a time where the growth of a community held strong through times of plague, wars, and numerous breakthroughs. A major legacy left by classical Greece was a government based on direct democracy. With a direct democracy, citizens ruled by majority vote. The citizenship was expanded to all free males, except foreigners. Those not considered citizens were women, slaves, and all foreigners
the main source of authority when it came to astronomy. The ideas and findings made by Greek philosophers spread and became widely accepted. The Greeks were first to discover that the Earth was spherical, and a particular Greek astronomer named Eratosthenes even measured the circumference of the Earth and the tilt of the Earth’s axis with incredible accuracy. Around 150 A.D., and astronomer named Ptolemy invented the...
2n-1(2n - 1) is a perfect number. The mathematician Euler (much later in 1747) was able to show that all even perfect numbers are of this form. It is not known to this day whether there are any odd perfect numbers. In about 200 BC the Greek Eratosthenes devised an algorithm for calculating primes called the Sieve of
flows downward into an inevitable center. This deterred the idea that the earth was flat. Aristotle observed that due to the movement of solid matter to a common center, the earth was undoubtedly spherical. Even after a century after Aristotle, Eratosthenes note...
