Curvature of the earth math
WebRecognizing the curvature of the Earth and knowing the distance between the two cities enabled Eratosthenes to calculate the planet’s circumference. Eratosthenes could measure the angle of the Sun’s rays off the vertical by dividing the length of the leg opposite the angle (the length of the shadow) by the leg adjacent to the angle (the ... http://mathcentral.uregina.ca/QQ/database/QQ.09.15/h/kevin1.html

WebNov 27, 2024 · If the Earth is round, then one marker should appear lower than the other when viewed at the same time through a telescope because the furthest marker would have fallen away with the curvature of ... Spherical Earth or Earth's curvature refers to the approximation of figure of the Earth as a sphere. The earliest documented mention of the concept dates from around the 5th century BC, when it appears in the writings of Greek philosophers. In the 3rd century BC, Hellenistic astronomy established the roughly spherical shape of Earth as a physical fact and calculated the Earth's circumference. This knowledge was gradually adopted throughout the Old World during Late Anti…
WebThe Earth does have a curvature but almost nobody ever notices it because the value is very small. For those in the know, the most precise value of curvature is about 8 inches per mile.
