Eratosthenes - He was a Greek mathematician who had a profound interest in geography. Ptolemy is known for his three scholarly works: the Almagest which focused on astronomy and geometry, the Tetrabiblos which focused on astrology, and, most importantly, Geography which advanced geographic knowledge. [24], Eratosthenes was described by the Suda Lexicon as a (Pentathlos) which can be translated as "All-Rounder", for he was skilled in a variety of things: He was a true polymath. He invented a system of latitude and longitude and he also might have calculated the distance from earth to the sun and invented the leap day.

Wyville Thomson suggested that the Royal Society of London ask the British government for the use of one of its ships for an extended . a. Eratosthenes of Cyrene developed longitude and latitude . 2011. He also calculated the tilt axis of the Earth. Eratosthenes also calculated the Sun's diameter. The numbers from one to 400 are written in a table, with the numbers one to 20 across the top row. The texts of his early works as a poet are not preserved either; however, some names were passed on to posterity through quotations from other Greeks. Which common nonsilicate mineral is used in wallboard.

The nematode They are a group of animal that are characterized by having a cylindrical body, without egmentation. A librarian named Hipparchus later placed lines of longitude at regular intervals, and this was improved even more by Ptolemy, who added cardinal directions and divided degrees into minutes and seconds. He returned to Cyrene and made such a name for himself in scholarly endeavors that the Greek ruler of Egypt brought him to Alexandria to tutor his son. The name Earth is an English/German name which simply means the ground. He studied in Athens at the Lyceum. ", Zhumud, Leonid.

Here Eratosthenes described his famous story of the well in Syene, wherein at noon each summer solstice, the Sun's rays shone straight down into the city-center well. The prime meridian plotted by Ptolemy was used by the Arabs for the calculation of time and longitudes. The course consists of an extensive examination of physical and cultural factors that contribute to and produce the variable character of the earth's surface and a discussion of the significance of . ". Eratosthenes used longitude in his maps, though the lines were placed irregularly so that they could pass through important landmarks. Prince Henry the navigators contribution to ocean exploration included? His prime number sieve provided a simple way for Greek mathematicians (and frustrated modern students!) [12] As he aged, he contracted ophthalmia, becoming blind around 195 BC.

Eratosthenes is famous for making the first good measurement of the size of the Earth. It is a large, submerged massif, about 120 km long and 80 km wide. The multiples of a given prime are generated starting from that prime, as a sequence of numbers with the same difference, equal to that prime, between consecutive numbers. (Writing before the Greeks adopted the degree, a Babylonian unit of measure, he actually said a fiftieth of a circle.) He correctly assumed the Suns distance to be very great; its rays therefore are practically parallel when they reach Earth. The word for a, Sulfates and Halides Gypsum is known in Colorado for mining gypsum, a mineral used in the construction of wallboard. The first spot has to go to the man who coined the term geography, Eratosthenes (c. 275-194 BC). What were the contributions of Eratosthenes, Hipparcus, and Ptolemy to oceanography? The simplified method works by considering two cities along the same meridian and measuring both the distance between them and the difference in angles of the shadows cast by the sun on a vertical rod (a gnomon) in each city at noon on the summer solstice. In this book Eratosthenes denounced. Boldly, they also sailed across the open ocean to settle Iceland and Greenland, even landing in North Americabecoming the first Europeans to do so. He was appointed as the Librarian of the Library of Alexandria-the post of highest academic honour of that period. He also devised a system for discovering prime numbers as whole numbers that can only be divided by themselves or the number 1. Eratosthenes calculates circumference of Earth, invents latitude and longitude 230 B.C. In addition, he calculated approximate distances between them.

Scientific Oceanography James Cook - 1768- HMS Endeavor very talented navigator, cartographer, writer, artist diplomat, sailor, scientist, dietition Scientific Contributions: 1. There it remained, approximately, for 25 years. The first person to determine the size of Earth was Eratosthenes of Cyrene, who produced a surprisingly good measurement using a simple scheme that combined geometrical calculations with physical observations.

However, it was in geography where he proved to be more skillful for he was one of the greatest of all ancient geographers. Eratosthenes made several important contributions to mathematics and science, and was a friend of Archimedes, the great mathematician. Eratosthenes also calculated the distance from the Earth to the Moon and to the Sun, but with less accuracy. At present it is known that the equatorial diameter is 40,075 kilometers. Life. "La climatologie d'ratosthne Posidonios: gense d'une science humaine". 3. Menu. He could then use simple proportions to find the Earths circumference 7.2 degrees is 1/50 of 360 degrees, so 800 times 50 equals 40,000 kilometers. establishing a center for the study of marine science and navigation in Portugal. He was born in 271 BC in Cyrene, which is now known as Libya, in North Africa. The first spot has to go to the man who coined the term geography, Eratosthenes (c. 275194 BC). He created one of the earliest maps of the known world between 276-195 BC, but his greatest contribution was the concept of latitude and longitude. He is regarded as the first scientific geographer who measured the length of the equator almost accurately (24860 miles) on sound principles with the help of gnomon. He created a longitude and latitude system, as well as a map of the world. Eratosthenes introduced latitude and longitude. He is best known for being the first person known to calculate the circumference of the Earth, which he did by using the extensive survey results he could access in his role at the Library; his calculation was remarkably accurate. Your email address will not be published. This is where, according to Pliny, "The world was grasped." He found the circumference of the Earth to be nearly 250,000 stadia (25,000 miles). Eratosthenes was the first person to use the word "geography" and other geographical terms that are still in use today, and his efforts to calculate the circumference of the Earth and the distance from the Earth to the Sun paved the way for our modern understanding of the cosmos.
