  “A sharp eye and an ingenious mind are at work on every page. . . . Read this book. . . . Then go forth, enjoy the view, and impress your friends.” —Laurence A. Marschall, Natural HistoryHow heavy is that cloud? Why can you see farther in rain than in fog? Why are the droplets on that spider web spaced apart so evenly?If you have ever asked questions like these while outdoors, and wondered how you might figure out the answers, this is a book for you. An entertaining and informative collection of fascinating puzzles from the natural world around us, A Mathematical Nature Walk will delight anyone who loves nature or math or both.John Adam presents ninety-six questions about many common natural phenomena—and a few uncommon ones—and then shows how to answer them using mostly basic mathematics. Can you weigh a pumpkin just by carefully looking at it? What causes the variations in the colors of butterfly wings, bird feathers, and oil slicks? And why are large haystacks prone to spontaneous combustion? These are just a few of the questions you'll find inside. Many of the problems are illustrated with photos and drawings, and the book also has answers, a glossary of terms, and a list of some of the patterns found in nature. About a quarter of the questions can be answered with arithmetic, and many of the rest require only precalculus. Regardless of math background, readers will learn from the informal descriptions of the problems and gain a new appreciation of the beauty of nature and the mathematics that lies behind it.“Remarkably lucid. . . . ordinary math becomes adventure.” —Booklist

  Great Sierra Waters The Eastern...

  Great Sierra Waters, the Eastern Slope is a definitive study of the Truckee River but also includes the Owens and the East Walker.  It's a serious fly-fishing book that shows you how to fish these rivers, what to use as far as fly patterns, and how to tie them for your greatest success. In addition to the fishing information which represents 60 years of fishing knowledge by the author, it details the plight of the Lahontan Cutthroat that has existed in the Truckee River drainage for 10 million years. This drainage runs from Lake Tahoe to Pyramid Lake and the Cutthroats have been famous since the 1930's when fishermen flocked from all over the world to fish for them.  
  In the last twenty years the original strain was found in a few tributaries in the Pilot Peak range of north central Nevada. They have taken hold again in Pyramid Lake and fish in excess of 30 pounds are currently available and they're running up the Truckee to spawn.  The demise of the Truckee began with the building of Derby Dam in the early 1900s.  The last great spawning run occurred in 1938, and the average fish weighed 18 1/2 pounds.  The last great Cutthroat trout was caught in 1949 in downtown Reno, Nevada and weighed twenty-two pounds and ten ounces.  
  As a boy, author Terry Courtright fished it constantly from the time he was 10 years old until he left for college.  He later came back and wrote outdoor columns about fly fishing the Truckee, then moved back to Montana to fish all of the great waters in the West.  As we speak, there is a great resurgence of interest in recovering this fish in this fishery and Courtright's last chapter on this book called The Restoration of the Lahontan Cutthroat brings to light the most sophisticated and workable fisheries plan that has ever been developed.  Great Sierra Waters is a welcome and timely addition to knowledge of the trout fisheries everywhere.

  The Alien Perspective - A New...

  Astronomer and science writer David Whitehouse takes us on a journey through the evolving cosmos as he considers humankind's place in the universe - and how our survival depends on otherworldly perspectives.
  
  From the Earth to the depths of outer space, this inspiring book shows how human evolution has been intertwined with the workings of the cosmos from the very beginning, and what the far-distant future may hold, both for the universe and for ourselves.
  
  Given enough time, Whitehouse contends, we must communicate with intelligent aliens whose divergent perspective will transform our understanding of the universe. First contact may even come sooner than we think. We have already transmitted signals towards promising exoplanets. If, say, Gliese 581d harbours life, the return signal could reach us in 2051.
  
  Drawing the thread of human consciousness from the cave to the cosmos, the acclaimed author of Apollo 11: The Inside Story charts our future journey to the end of space and time and considers whether something of humanity could remain at the end of it all.
