Calculating God $9.99 Calculating God is the new near-future SF thriller from the popular and award-winning Robert J. Sawyer. An alien shuttle craft lands outside the Royal Ontario Museum in Toronto. A six-legged, two-armed alien emerges, who says, in perfect English, "Take me to a paleontologist." It seems that Earth, and the alien's home planet, and the home planet of another alien species traveling on the alien mother ship, all experienced the same five cataclysmic events at about the same time (one example of these "cataclysmic events" would be the meteor that wiped out the dinosaurs). Both alien races believe this proves the existence of God: i.e. he's obviously been playing with the evolution of life on each of these planets. From this provocative launch point, Sawyer tells a fast-paced, and morally and intellectually challenging, SF story that just grows larger and larger in scope. The evidence of God's universal existence is not universally well received on Earth, nor even immediately believed. And it reveals nothing of God's nature. In fact. it poses more questions than it answers. When a supernova explodes out in the galaxy but close enough to wipe out life on all three home-worlds, the big question is, Will God intervene or is this the sixth cataclysm:? Calculating God is SF on the grand scale.   Calculating God is a 2001 Hugo Award Nominee for Best Novel. |

Calculating the Weather $120 During the course of this century, meteorology has become unified, physics-based, and highly computational. Calculating the Weather: Meteorology in the 20th Century explains this transformation by examining thevarious roles of computation throughout the history of meteorology, giving most attention to the period from World War I to the 1960s. The electronic digital computer, a product of World War II, led to great advances in empirical, theoretical, and practical meteorology. At the same time, the use of the computer led to the discovery of so-called"chaotic systems,"and to the recognition that there may well be fundamental limits to predicting the weather. One of the very few books covering 20th century meteorology, this text is an excellent supplement to any course in general meteorology, forecasting, or history of science. Key Features * Provides a narrative account of the growth of meteorology in the 20th century * Explains how forecasting the weather became a physics-based science * Studies the impact of the computer on meteorology and thus provides an example of science transformed by the computer * Describes three traditions in meteorology: * The empirical tradition of gathering data and making inferences * A theoretical tradition of explaining atmospheric motions by means of the laws of physics * The practical tradition of predicting the weather * Analyzes the increasing role of calculation within each of the traditions and explains how electronic digital computers made possible many connections between traditions |

Calculators - a Boon or a Bane
A calculator is a device, usually hand-held, for calculating mathematical expressions. In the past, calculations were done in the head, on paper or by a semi-manual machine. But, this process of semi-manual calculation was time-consuming and prone to errors. Working out large sums in the head was not for everyone and calculations done on paper also were not totally error-free. Then came calculators designed to simplify all those complicated mathematical calculations. In the beginning, these electronics devices were very expensive. This was because the mechanical and electrical parts of the calculator were expensive to produce. However, as the prices of these parts fell and production techniques became better, calculators, too, became less costly and in fact, were very soon easily affordable to the average person.
In the past, calculators were as big as computers today but, soon, pocket-sized devices were available. Calculators can come in hardware or software versions and they can be mechanical or electronic. They are built into computers, mobile phones, pagers and even wrist-watches. Modern calculators are normally electrically powered and may range from small, wallet-sized models to strong adding-machine like models. These powerful calculators may also have printers in-built in them.
A basic calculator has a power point, a display unit, electronic circuit and a keypad. The keypad consists of ten digits from 0-9, equals signs, the decimal point, a cancel or clear button, on and off buttons and offers the basic mathematical calculations of addition, subtraction, multiplication and addition besides having square root and percentage calculations.
There are now many advanced variations of calculators available, each performing a specific function. For example, the scientific calculator is designed for advanced mathematics like trigonometry and statistics. The financial calculator will help in accounting and real-estate deals. The mortgage ones will show you what exactly you have to pay on your house. Apart from these there are loan, lease, time, love, area, temperature and the most advanced of them all, graphing calculators. These are all basically online calculators but they do have certain anomalies, like, if the numbers get too big or too small, some errors in calculations can occur.
The easy availability of calculators has made people dependent on them to a certain extent and most of them do all their calculations on calculators. This has its own followers as well as detractors. Some believe that using calculators hamper the basic mathematical skills of people, especially students, by making them poor in instant calculations.
In many countries, students are allowed to use calculators in their school-work because it is felt that problem-solving and estimation techniques can be taught more easily through calculators. Others worry that students may use the calculator in the wrong way unintentionally and, yet, believe the answer because that was the result shown. This type of error can take place outside school rooms also. Anyone using the calculator incorrectly will believe the wrong answer to be the right one. This might happen in shopping malls or even during business transactions.
In schools, teachers try to tackle this by asking the students to first make an approximation of the answer manually and then compare it to the calculated result. But, overall, this does hamper the child`s learning process because he or she may not understand the logic behind the answer. In such a case, calculators become more of a hindrance than a help.
Of course, when one is involved in lengthy financial calculations, these devices come in very useful. Even if one is on a holiday abroad calculators are handy for those quick conversions of currency and saves you valuable time trying to figure out the conversion rates.
