Extractions: This award-winning globe could help children become A+ geography students. The Explorer Globe II is jam-packed with hundreds of facts, trivia, and useful scholastic information about every aspect of the geographical world. It electronically verbalizes everything from area population, capitol city/country, state/province, large bodies of water, currencies, high points, distance, and more. Other remarkable features make the Explorer an even more useful reference tool. It has a world clock that, once set from your home area, will tell the time in every other part of the world. And any country can be selected to hear a sample its national music (yes, Tahiti does have a national anthem). The globe sits on a sturdy base, which features a dashboard full of interactive functions and an attached soft-tipped stylus. This stylus is the key instrument: use it to touch virtually any point on the surface of the globe to retrieve information. Diane Beall

Extractions: Ludolph Van Ceulen does not appear to have had a university education as his parents were not sufficiently wealthy to pay for one. He held a number of posts not only as a teacher of mathematics but also as a fencing teacher. He taught fencing and mathematics in Delft, then in 1594, opened a fencing school in Leiden. In 1600 he was appointed to the Engineering School in Leiden. For the last ten years of his life he taught arithmetic, surveying and fortification in the engineering school. Van Ceulen is famed for his calculation of p to 35 places which he did using polygons with 2 sides. He spent most of his life doing this and it is fitting that the 35 places of p are engraved on his tombstone. In Germany p was called the Ludolphine number for a long time. Van Ceulen had several friends among the mathematicians of the time. In particular his friendships with Simon

Extractions: Dictionaries: General Computing Medical Legal Encyclopedia Word: Word Starts with Ends with Definition The year 1600 CE in science For the journal named Science , visit Science (journal). Science (from scientia, Latin for "knowledge") refers to the systematic acquisition of new knowledge about nature and the body of already existing knowledge so gained. The scientific method is based on careful observation and the testing of theories by experiment. Science does not claim to make any statements about how nature actually "is", for the scientist should know that we can only make conclusions about our observations of nature. The development of Quantum Mechanics in the early 20th century showed us that our observations equate to interactions, and the incredible implications of wave-particle duality made "objectivity" in science practically impossible. Click the link for more information. and technology Technology has more than one definition. One is the development and application of tools, machines, materials and processes that help to solve human problems. As a human activity, technology predates both science and engineering. The term technology thus often characterises inventions and gadgets using recently-discovered scientific principles and processes. However, even very old inventions such as the wheel exemplify technology.

Extractions: var cm_role = "live" var cm_host = "angelfire.lycos.com" var cm_taxid = "/memberembedded" Ludolph van Ceulen Two thousand years ago, the ratio between the circumference of a circle and its diameter was taken to be "3". Although the value was close, as time went on efforts were made to refine the ratio to a more precise constant. Greek mathemetician, Archimedes, correctly asserted that it fell between 3 10/70, and 3 10/71. In the computer age, the number has been calculated to the one millionth decimal place, and has been determined to be an irrational number, without a finite definition. Ludolph van Ceulen was born at Hildesheim, Germany, 28 January, 1540. Like many Germans during the Catholic Inquisitions, he emmigrated to The Netherlands. He taught Fencing and Mathematics in Delft until 1594, when he moved to Leiden and opened a Fencing School. In 1600 he was appointed to the Engineering School at Leiden, where he spent the remainder of his life teaching Mathematics, Surveying, and Fortification. He wrote several books, including one titled "On The Circle", in

I'm looking for information on Ludolph van Ceulen. The Internet site I went to said he approximated pi to the first 35 digits by inscribing polygons in a circle. 1) How do you figure out pi this way? The site also said he used polygons with 2 to the 62nd power sides. My friend said that making a polygon with this many sides is impossible by human hand. And then he gave a reasonable argument. 2) So my second question is how did van Ceulen make such a large polygon? http://mathforum.org/dr.math/ Associated Topics

The stone will be placed in the Pieterskerk (St. Pieter's Church) in Leiden (Netherlands) at the some spot as his lost gravestone. On the memorial stone Ludolph's 35 decimal digits of Pi will be engraved. In the afternoon and in the evening Pieter Borwein will give the Beeger lecture 2000 at the Leiden University (it's on Pi).
