Extractions: Willebrord van Roijen Snell Abstract: Perhaps the most fundamental principle of geometrical optics is the Law of Refraction.(1) As light travels from one medium to another it undergoes what is called refraction, or a bending of its path. Snell discovered that this bending was dependent upon three things - the index of refraction of the medium the light is in, the index of refraction the light is entering, and the angle of incidence for the ray at the interface. It was from these observations that Snell was able to derive the Law of Refraction, which is often referred to as Snell's Law. Biography: Willebrord van Roijen Snell was born in 1580 in Leiden, Netherlands. Willebrord's father was a professor of mathematics at the University of Leiden. It was a passion that Willebrord himself shared, although initially as a student Snell studied law. Snell entered the University at a very young age and and by the age of twenty he was traveling through Europe discussing astronomy in various countries. Willebrord was using his knowledge and passion for mathematics and applying it to some revolutionary work in astronomy. In 1617 Snell published Eratosthenes Batavus

Extractions: Willebrord Snell studied law at the University of Leiden but was very interested in mathematics and taught mathematics even while he studied law. From about 1600 he travelled to various European countries, mostly discussing astronomy. In 1602 he went to Paris where his studies continued. He received his degree from Leiden in 1607. Snell's father, Rudolph Snell (1546-1613), was professor of mathematics at Leiden and, in 1604, Willebrord visited Switzerland with his father. In 1613 he succeeded his father as professor of mathematics at the University of Leiden. In 1617 Snell published Eratosthenes Batavus , which contains his methods for measuring the Earth. He proposed the method of triangulation and this work is the foundation of geodesy. Snell also improved the classical method of calculating approximate values of p by polygons. Using his method 96 sided polygons give

His father was a scholar and professor of mathematics at the University of Leiden. Snell entered the University of Leiden at a relatively young age where he originally studied law. His attention soon turned to mathematics and he was teaching at the university by the time he was 20 years old. After finishing with his degree at the university, he traveled to eastern Europe and visited most of the major astronomers of the day. In 1613, Snell succeeded his father as professor of mathematics at Leiden and in 1617, he published "Eratosthenes Batavus", which explained his methodology for measuring the Earth by triangulation. Snell had difficulty completing his work until the brother barons Sterrenberg took over and finished it with his assistance. This important work wove the foundations of modern geodesy. Snell also published other works, including his work on comets and in 1624, he published "Tiphys Batavus", a work on navigational theories. His work in mathematics allowed him to produce an improved method of calculating approximate values of pi using polygons. This method, using 96-sided polygons, produce a value of pi correct to seven places, a striking improvement to the classical method that yielded only two places.
