Wolfram Mathematica: Graphing Calculators: Comparative Analyses Although now rare in college and professional settings, graphing calculators are still common in high-school math education. But as full-scale computers become cheaper, smaller and ever more ubiquitous, the future of standalone calculators is increasingly unclear. As the world's broadest and deepest mathematical system, Mathematica's computational capabilities vastly exceed anything that can be achieved with a calculator—and provide a completely different level of educational possibilities. While calculators are easy to use for simple operations, they rapidly become unwieldy when many steps are required. Mathematica, on the other hand, is immediately able to offer a fully scalable interface with dramatically more compelling graphics and interactivity, as well as greater systematic learnability.

The Thirty Greatest Mathematicians Click for a discussion of certain omissions. Please send me e-mail if you believe there's a major flaw in my rankings (or an error in any of the biographies). Obviously the relative ranks of, say Fibonacci and Ramanujan, will never satisfy everyone since the reasons for their "greatness" are different. I'm sure I've overlooked great mathematicians who obviously belong on this list. Fibonacci in Nature The Fibonacci numbers play a significant role in nature and in art and architecture. We will first use the rectangle to lead us to some interesting applications in these areas. We will construct a set of rectangles using the Fibonacci numbers 1, 1, 2, 3, 5, 8, 13, 21, and 34 which will lead us to a design found in nature. You will need a ruler, protractor, and compass. Start by drawing two, unit squares (0.5 cm is suggested) side by side.
