On May 18, 2009, British computer scientist Stephen Wolfram officially launched a new search product called Wolfram|Alpha (WA). This launch was preceded by months of speculation and hype online about exactly what WA would be and how it would compare to Google and other search engines. This article will explore the basic features of WA, show some example queries and results, and discuss the usefulness and limitations of this new tool. 相似文献

This article is written to share teaching ideas about using commonly available computer applications—a spreadsheet, The Geometer's Sketchpad, and Wolfram Alpha—to explore three classic and historically significant problems from the probability theory. These ideas stem from the authors’ work with prospective economists, mathematicians, and teachers. The historical contexts include the problem of the division of stakes (14th century), the problem of the Grand Duke of Tuscany (17th century), and the problem of co-primality of two natural numbers chosen at random (19th century). The suggested use of computers can be extended to other probability contexts to achieve at least two goals: to make complex mathematical ideas more accessible and to emphasize the importance of experimental evidence as a means of conceptual development in mathematics for all student populations. 相似文献
