Willebrord Snel van Royen's homestead - Homesteads on Waymarking.com

Willebrord Snel van Royen, better known by his Latin name Snellius, was a Dutch mathematician, physicist and astronomer. He was from 1613 to 1626 professor at the University of Leiden. He is mainly known for the law of refraction of light, but has also made an important contribution to the land surveying. In 1615 he devised a new method to calculate the circumference of the earth using triangulation.

Link to the Homestead: [Web Link] History if no Link: Snellius’s problem ‘Achterwaartse insnijding’ is a method of surveying the coordinates of the point of observation to be determined only by angular measurements to at least three other known points in the flat plane (2-dimensional). The method was used in the time that the accurate measurement of distances was not easy. The ‘achterwaartse insnijding’ is also known as 'Snellius’s problem' because Willebrord Snel was the first to find the solution. As the first in the history of surveying Snellius determined a point by ‘achterwaartse insnijding.’ Additional Parking or Point of Interest: Not Listed Structure Type: Not listed
