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. Wolfram Research, Stephen Wolfram, and Eric Weisstein settled with the CRC Press for an undisclosed financial award and several benefits. Among these benefits are the inclusion of a copyright notice of the CRC Press at the bottom of all webpages in MathWorld and legal rights to reproduce MathWorld in a book format again. ScienceWorld, also known as Eric Weisstein's World of Science, was unveiled to the general public in January 2002. ScienceWorld includes more than 1,000 entries in many fields of science including astronomy, chemistry, physics and biographies of scientists. Further scientific activities In 2014, he became a member of the Global Digital Mathematics Library Working Group of the International Mathematical Union.
