Athens- Baffling scientists for decades, the Antikythera Mechanism, an ancient astronomical computer, now has some more evidence as to just how old it is. Recent radiocarbon dating done on this device shows that it is from 150-100 BCE. Radiocarbon dating is based on the principal that radioactive carbon-dioxide found in minerals and rocks decays at a predictable rate. Radiocarbon is constantly being created in the atmosphere when cosmic rays interact with atmospheric nitrogen. When rocks and…

his existence are in his written works, which contain mathematic, scientific, astronomical, astrological, philosophical, musical, and geographic observations and inferences. A large portion of Ptolemy’s written work is based on the observations of Hipparchus, causing some historians to question the amount of original work Ptolemy has produced. Ptolemy’s mathematical achievements include trigonometry tables that have the ability to calculate the positions of various celestial bodies such as…

record observations in the sky using the telescope. Observers were able to look at things in space with good detail which eventually led to heliocentric ideas. Another invention that greatly helped explorers was the Astrolabe that was invented by Hipparchus in ancient Greece. Portuguese Sailors first started using the Astrolabe on seas in 1481. The astrolabe was able to measure the angle of the sun which could then be converted to find latitude, which greatly helped sailors find the exact point…

In the best of times, they were given land and stature while in the worst, vengeance, banishment and war. The Athenian embracement of democracy over monarchy can be attributed to the tyranny experienced under the rule of…

are the same. Astronomers use, what they called the apparent magnitude to measure the brightness of the object in the sky. The astronomer that divided the stars into six different magnitudes based on their brightness is the Greek astronomer, named Hipparchus, in the second century B.C, he also numbered the six classes of the stars from 1 to 6. 1 being the brightest through 6 being the brightest. As we come toward the modern days, the most advanced of the technology we have today to be able to…

Assess the Legacy of Alexander the Great Alexander the Great’s legacy was the spreading of Greek (Hellenistic) culture across a large part of the Middle East and Asia, and significantly increasing the relationship between the East and West, which led to improved trade and the sharing of ideas. During his 13 years of empire expansion, Alexander the Great transformed the world. He had numerous military successes, almost conquering the entire known world at the time, and he is considered one of the…
