Scientist
A scientist in a broad sense is one engaging in a systematic activity to acquire knowledge. In a more restricted sense, a scientist is an individual who uses the scientific method. The person may be an expert in one or more areas of science. This article focuses on the more restricted use of the word...

Spectroscopy
Spectroscopy is the study of the interaction between matter and radiated energy. Historically, spectroscopy originated through the study of visible light dispersed according to its wavelength, e.g., by a prism. Later the concept was expanded greatly to comprise any interaction with radiative...

This document contained a compendium of information that Weisstein had obtained throughout his studies. As Weisstein transferred to the University of Virginia to continue his work in astronomy, he continued to refine his fledgling encyclopedia. In November 1998, Weisstein made a deal with the CRC Press

 to publish his encyclopedia in book format titled, the CRC Concise Encyclopedia of Mathematics. One year later, in 1999, Weisstein accepted the position of encyclopedist at Wolfram Research, Inc. (WRI). MathWorld was ready to be unveiled in December 1999.

There are nearly 13,000 entries in MathWorld, nearly all of them authored by Weisstein. These entries encompass a variety of disciplines including algebra

MathWorld became involved in a legal dispute with the CRC Press in March 2000. The CRC Press claimed MathWorld violated the copyright on the CRC Concise Encyclopedia of Mathematics. During the dispute a court order shut down MathWorld for over a year starting October 23, 2000. According to Eric Weisstein’s personal site he restarted MathWorld on November 6, 2001. This ultimately led to the creation of PlanetMath
