Introduction to Space Flight Review

Average Reviews:

(More customer reviews)This book is an excellent introduction to both orbital mechanics and propulsion performance estimation as it applies to mission planning. While many of the topics are deeply rooted in hard core mathematics, Hale cuts to the chase and presents useful information up front without forcing the reader to wade through countless proofs. As a result, this book is useful for everyone from a high school student interested in the topic to a professional working in the field. Is it the definative work on the topic? I don't believe so. But I do believe that if you only own one book on the topic, you can't go wrong with this one.

Mapping: Ways of Representing the World Review

Average Reviews:

(More customer reviews)Finding this book in the geography section of one of my favorite bookstores was, well, "a find," and especially so because there is a lot masquerading as "geography" or "mapping" these days.
This, as it happens, is the real thing. The British authors have constructed a kind of dream volume for those who want to boost the visual or geographic literacy of their friends, children, neighbors, or students. 'Tisn't a book just for geographers, though those in that profession will love this item. It's at least as much for the many, many, many folks in the world who understand that they don't know what they should about how the world is expressed in maps, and who feel more than a passing need to remedy that inadequacy.
Who's this for? I'd say anyone who has read and learned from the work of Edward Tufte, and as much, for those who revel in the writings of Mark Monmonier, cartography's current gray eminence and a brilliant scholar to boot. But this is also for those who just love maps: The Thelin and Peak SLAR map of the lower 48 states, Erwin Raisz's work, or the luminous cartographer of such great as Eduard Imhof.
The sole drawback is the price -- that's a pocketful of change, and were the ducats sought a few less, this would be a five-star choice, hands down.
Read it, love it, and learn.

Illustrates how maps tell us as much about the people and the powers which create them, as about the places they show. Presents historical and contemporary evidence of how the human urge to describe, understand and control the world is presented through the medium of mapping, together with the individual and environmental constraints of the creator of the map.
