This book describes systems of calculus, called meta-calculi, that arose from the problem of measuring stock-price performance when taking all intermediate prices into consideration. The meta-calculi provide mathematical tools for use in science, engineering, and mathematics. They appear to have potential for use as alternatives to the classical calculus of Newton and Leibniz. It may well be that they can be used to define new concepts, to yield new or simpler laws, or to formulate or solve problems.

This book concerns the averages of functions that arise in the development of non-Newtonian calculus and weighted non-Newtonian calculus, and an interesting family of means of two positive numbers. These averages and means provide a wide variety of mathematical tools for use in science, engineering, and mathematics. It may well be that they can be used to define new concepts, to yield new or simpler laws, or to formulate or solve problems.

This book explains how each non-Newtonian calculus, as well as the classical calculus of Newton and Leibniz, can be 'weighted' in a natural way. In each of these weighted calculi, a weighted average (of functions) plays a central role. The weighted calculi provide a wide variety of mathematical tools for use in science, engineering, and mathematics. They appear to have considerable potential for use as alternatives to the classical calculus. It may well be that they can be used to define new concepts, to yield new or simpler laws, or to formulate or solve problems.

Have you ever dreamed of running away to a tropical island? In 1996 Jane Grossman left behind a comfortable life in Chicago and set off on with her husband on their 34-foot sailboat, Iniki, to sail South America. What began as a chance to simplify their lifestyle and to see the islands gradually evolved to a sojourn of self-discovery, renewal and triumph over breast cancer. "Windshifts" is a true sailing adventure that chronicles the wonder and excitement, the difficulties and fears from a woman's perspective. Vivid details and delightful descriptions of exotic lands, cultural interactions and inevitable conflicts of a husband and wife confined to close quarters involve the reader with all of their senses. More importantly, it is a reflection on dealing with the unexpected challenges that confront us all throughout our lives.

From the virtual museum of Victorian architecture that is Back Bay to the charming Federal-style homes of Beacon Hill to history-rich Charlestown, Boston Foot Notes takes you on a fascinating series of walks that will educate and entertain. Walks range from 2 1/4 to 3 1/2 hours in length. This revised edition also includes a new section on the Rose Kennedy Greenway.
