Eratosthenes circumference error. This feat was more than simply a scientific achievement.

Eratosthenes circumference error. This feat was more than simply a scientific achievement. Using elegant mathematical reasoning and limited empirical measurement, in approximately 240 b. C. Eratosthenes learned that the sun is directly overhead at noon on the summer solstice in Syene. Here's how. Today, the earth's circumference is usually accepted to be 40,096 kilometers (24,901 miles). If you take the lowest estimate attributed to Eratosthenes, his error was less than one percent—a phenomenal calculation. From his measurement, and assuming the Earth is spherical, Eratosthenes Since Alexandria is directly north of Syene, Eratosthenes was estimating the polar circumference of the earth which is slightly smaller than the equatorial circumference. Read about the Greek Mathematician Eratosthenes, who created a methodology for finding the circumference of the Earth within a fraction of error! Jun 17, 2024 · Eratosthenes’ accomplishment in measuring the Earth’s circumference was not only a significant achievement in the field of astronomy but also in the history of science. c. Oct 19, 2023 · Table of Contents (click to expand) Eratosthene calculated the circumference of Earth by measuring the length of a stick’s shadow in Alexandria and the distance between Alexandria and Syrene on foot. Multiplying these two figures, Erasthostenes found that the circumference of the earth should be 250,000 stadia, or about 40,000 km. Jun 1, 2023 · The goal is not simply to measure the length of the stick and its shadow, but to understand Eratosthenes’ logic behind these simple measurements, and thus, highlight his ingenuity, since almost 2300 years ago he calculated the circumference of the Earth with relatively great accuracy. This task is intended mainly for instructional purposes, giving an interesting context for implementing ideas from geometry and trigonometry. , Eratosthenes of Cyrene (276-194 b. He calculated the total circumference of the Mar 26, 2024 · In 240 BC, Greek astronomer, geographer and mathematician Eratosthenes calculated the circumference of the Earth without even leaving Egypt. Introduction You will measure the circumference of the earth using a method first performed by Eratosthenes in 240 B. He measured the length of the shadow cast by a vertical rod in Alexandria at noon on the summer solstice. He is best known for being the first person known to calculate the Earth's circumference, which he did by using the extensive survey results he could access in his role at the Library. May 27, 2024 · One of the most remarkable contributions to this understanding was made by Eratosthenes of Cyrene, a Greek mathematician, geographer, and astronomer who is best known for his pioneering calculation of the Earth's circumference around 240 B. This measurement was incredibly accurate for the time and found the circumference within 1% of the figure we found today. Explore Eratosthenes' method for measuring Earth's circumference, error analysis, and related extensions. How Eratosthenes Measured the Circumference of the Earth In today's lab we will show how Eratosthenes, a Greek mathematician, was able to estimate the circumference of the Earth using a sundial and some information about shadows in a `nearby' city. He then took the inverse tangent of the ratio between the shadow’s length and the stick’s length to find the angle of inclination of the Sun.
