BOOK FACT FRIDAY

FACT: “In the treeless Aleutian Islands, Bald Eagles nest on the ground. Small sticks are picked up or broken off and carried in the beak; large ones are carried in the talons. In the center of the platform a cup 3-5in (7.5-13cm) deep, lined with grass and mosses is formed. Large nests can weigh two tons and last for over 50 years.”

Avian Architecture: How Birds Design, Engineer, and Build
Peter Goodfellow

Birds are the most consistently inventive builders, and their nests set the bar for functional design in nature. Avian Architecture describes how birds design, engineer, and build their nests, deconstructing all types of nests found around the world using architectural blueprints and detailed descriptions of the construction processes and engineering techniques birds use. This spectacularly illustrated book features 300 full-color images and more than 35 case studies that profile key species worldwide. Each chapter covers a different type of nest, from tunnel nests and mound nests to floating nests, hanging nests, woven nests, and even multiple-nest avian cities. Other kinds of avian construction—such as bowers and harvest wells—are also featured.

Avian Architecture includes intricate step-by-step sequences, visual spreads on nest-building materials and methods, and insightful commentary by a leading expert.

-Illustrates how birds around the world design, engineer, and build their nests

-Features architectural blueprints, step-by-step sequences, visual spreads on nest-building materials and methods, and expert commentary

-Includes 300 full-color images

-Covers more than 100 bird species worldwide

“[Goodfellow] sharpens the focus to explore nests only from the perspective of their architecture—their form, function, construction materials, how they are made, and by whom. . . . We love finding nests but rarely pay attention to how they are built. Avian Architecture will magnify your sense of wonder. The book is chockablock full of detail presented in a very accessible way.”—Wayne Mones, Audubon.org

Dialogue with Howard Wainer, author of Uneducated Guesses

Howard Wainer’s most recent book, Uneducated Guesses, is both a challenge to education policymakers and a warning to the country about the misguided policies that shape our nation’s educational system. Wainer uses statistical evidence to uncover the problems that threaten education in the United States in a book that is both accessible and eye opening for any reader. We recently posed some questions to Professor Wainer and are thrilled to post this dialogue about various issues he addresses in his book.




PUP: You discuss a lot of issues surrounding college and university admittance in Uneducated Guesses, one of which is the choice to not require the SAT. Do you think some schools shifting towards not requiring the SAT for admittance will cause more schools to follow suit?


Professor Howard Wainer: I hope not. Right now there are powerful forces pushing some schools to abandon admission tests. One of the most insidious is how making such tests optional artificially boosts the school’s US News & World Report rankings. I hope that by exposing such strategies it will help to stifle such policies.

David Weintraub’s most recent book, How Old Is the Universe?, is a readable investigation of the title question that explains how we have arrived at an approximate age of 13.7 billion years for the universe. Weintraub works his way from biblical chronology of the origins of the universe to the high-tech astronomy research taking place today in this accessible and entertaining history. We recently posed some questions to Prof. Weintraub by email and are pleased to present this dialogue.



PUP: I am not an astronomer, so I was relieved to discover I could actually read How Old Is the Universe? You clearly went to great efforts to make the text accessible. How difficult was it to break down these big scientific ideas, terms, and facts for general readers?

Professor David Weintraub: Making sure I was speaking to a non-professional audience in English rather than in the jargon-filled language of astronomy was a constant challenge. A major goal with this book is to help general-audience readers understand the complicated and unfamiliar concepts described between the covers. Consequently I focused on this issue quite literally with every word I wrote. At the risk of being struck down by the gods for hubris, I do think I have done better at this than most astronomers who are trying to communicate with a non-professional audience. Nevertheless, more than a few of my descriptions passed through my ‘language of the lay reader’ filter unnoticed by me. Fortunately, Princeton University Press assigned my manuscript to an editor who asked me lots of excellent questions for clarification, and quite often her questions arose when she bumped into a piece of text in which the meaning was unclear to her because of my too-technical word choices. I do think, in the end, the presentation of difficult concepts in this book is accessible to the general reader because we paid such close attention to language and because I continually reminded myself of whom the readership of the book is intended to be. My editor was a humanist who knew no astronomy before beginning to edit the book. So she was my test reader; if she didn’t understand my words, I flunked the test. When we were done, she felt that she understood every word and had learned and now understood everything in the book. Fortunately for her and all readers, unless you are in one of my classes, there is no test at the end of each chapter.

Our author Nicholas Humphrey was on the airwaves recently discussing consciousness and his eye-opening new book SOUL DUST: The Magic of Consciousness. On July 7 he chatted with Virginia Prescott on New Hampshire Public Radio’s Word of Mouth about the book. And, on July 11, he discussed the book on SETI Radio. For some engrossing conversation about how science can explain what we think of as “the soul,” then check out these interviews!

SOUL DUST, Nicholas Humphrey’s new book about consciousness, is seductive–early 1960s, ‘Mad Men’ seductive. His writing is as elegant, and hypnotic, as that cool jazz stacked on the record player. His argument feels as crystalline and bracing as that double martini going down, though you might find yourself a little woozy afterward. And his tone is as warm and inviting as that big, crackling fire, even if the dim flicker does leave things a bit obscure in the corners. . . . [SOUL DUST] is not only thoroughly enjoyable but genuinely instructive, too.”
– Alison Gopnik, New York Times Book Review

Nature’s Geometry

The geometry we learned in high school is ideal for describing “man-made” forms such as buildings, roads, fences, etc. But lines, circles, and triangles don’t seem to do justice to trees, clouds, or mountains. What about the forms of nature? Is there a geometry for them? The late mathematician Benoit Mandelbrot (1924-2010) pioneered just such a geometry; he called fractal geometry after the Latin word fractus, which means broken or irregular.

A fractal is a shape composed of smaller copies of itself (think “fractured”). For example, a cauliflower is composed of florets—little flowers—which look just like little cauliflowers. We can use this idea to draw many natural forms using precise, step-by-step methods called algorithms. In the figure below we start with a simple, three-stick tree in (a) and then repeatedly turn each branch tip into a smaller, three-stick tree. The last step (f) is a computer rendering of the fractal the shapes are converging to.

Step-by-step drawing of a fractal tree.

The close-up below illustrates one of the reasons Annalisa Crannell and I chose the striking photograph Winter Road along the Trees by Wil Van Dorp for the cover of Viewpoints: Mathematical Perspective and Fractal Geometry in Art. The fractal beauty of the trees was impossible to resist!



Detail of the cover of Viewpoints.

Nowadays computers use fractal algorithms to generate photographically real landscapes in many feature films that require special effects. However, mathematicians and computer scientists may not have been the first to follow this road. As Benoit Mandelbrot pointed out, Asian artists have employed fractal-like portrayals of natural forms for centuries. As you can see below, Japanese woodblock artists of the nineteenth century used abbreviations for natural forms that are surprisingly similar to fractals investigated by mathematicians and scientists more than a century later!

Rothschild Lauded by Former Prime Minister

On Tuesday afternoon Princeton University Press had the honour of sponsoring a celebration of Emma Rothschild’s new book, THE INNER LIFE OF EMPIRES, at the University of Edinburgh, at the generous invitation of the Rt Hon Gordon Brown, MP. Lauded in the Wall Street Journal, The Spectator, and the Economist, Prof Rothschild’s book describes the complex world of empire, economy and enlightenment in the 18th century by telling the story of the extraordinary Johnstone family – 11 siblings who were born in Scotland and became abolitionists, speculators, slave owners, government officials and politicians and whose careers spanned the globe. Speaking about the origins of the book, Professor Rothschild described how a question from Gordon Brown about a parliamentary election in Adam Smith’s home town of Kirkcaldy led to the chance discovery of the letter book of John Johnstone and the world of his family. Dr Brown praised Rothschild’s pioneering research in economic history and the thought of Adam Smith, describing how the globalized world of the 18th century Johnstones which stretched from Grenada to India, has much to teach us about the current crisis of globalization.

Other speakers at the event included Nicholas Phillippson, biographer of Adam Smith and David Hume, and Sir Raymond Johnstone, descendant of John, who charmingly described his ancestors as “Borders Reivers.”

THE INNER LIFE OF EMPIRES is available in hardcover and in electronic form from Princeton University Press.

Perspective by the Numbers as Art Appreciation

One of the best types of art appreciation course is a straight-up studio course in painting, drawing, or sculpture. Even a few lessons can provide a better grasp of the talent and discipline that go into the artwork we see in galleries and museums. But what about the contemporary art we see in movie theaters? More and more of what we see on the movie screen is computer-generated imagery (CGI), including entire films by the big animation studios such as Pixar, DreamWorks, and Industrial Light & Magic. Are there art appreciation lessons for this type of art?

It so happens there are. While a complete understanding requires a fairly advanced knowledge of mathematics and computer graphics, a good grasp of the basics requires only elementary mathematics and access to computer spreadsheet software. Annalisa Crannell and I devote a chapter to this in Viewpoints: Mathematical Perspective and Fractal Geometry in Art. One of my students, Tia, chose this medium for her final project. Although Tia was a biology major, you can see from the samples below that she was able to design a nice mathematical model of a lamp and lampshade, and use a spreadsheet to visualize them from any angle.


Part of a student’s final project

Tia’s project included multiple, hand-colored drawings made from scatter plots she generated in Microsoft Excel. This hybrid approach gives a good feel for the power of computers in 3-D imagery, without losing the connection between the relevant mathematics and the final artwork. The quality of her images underscores an important advantage of doing perspective by the numbers like this. Namely, it acts as a kind of safety net for people who lack talent or confidence in drawing, allowing them to make images that art majors would be equally proud of.

BOOK FACT FRIDAY

FACT: Following the Amarna period of the new Kingdom, around 1200 BCE, Egyptians invented a simple device known as the shaduf, which, using a fulcrum, lifted a water bag that enabled cultivators to irrigate the lands from the spring and summer low-water nile. Shadufs made it possible to grow winter crops, such as cotton and additional cereals.

Egypt: A Short History
Robert L. Tignor

Egypt: A Short History is a sweeping, colorful, and concise narrative history of Egypt from the beginning of human settlement in the Nile River valley 5000 years ago to the present day. Accessible, authoritative, and richly illustrated, this is an ideal introduction and guide to Egypt’s long, brilliant, and complex history for general readers, tourists, and anyone else who wants a better understanding of this vibrant and fascinating country, one that has played a central role in world history for millennia—and that continues to do so today.

“Robert L. Tignor’s ambitious Egypt: A Short History stretches from the Predynastic age to the present, tying the various periods together in a continuous 5,000-year narrative to create a lengthy history told in a short book. . . . Tignor writes with an easy, assured style, and his history becomes more focused and more authoritative as it progresses. He tells us it was conceived as an alternative guidebook for discerning tourists wishing to learn about more than just pyramids and pharaohs: as such—as an enjoyable book written by someone who clearly knows and loves Egypt and the Egyptians—it serves its purpose very well.”—Financial Times

“This is a masterpiece. In simple and accessible prose, Robert Tignor builds on his long and deep familiarity with Egyptian history, politics, and economy. The reader comes away with an understanding of what propels Egyptian history over the ages, and an appreciation of the key questions that beleaguer modern Egypt. This book will be of enormous value for general readers, students, and tourists.”—Khaled Fahmy, New York University

This year marks the 50th anniversary of the building of the Berlin Wall. The wall represented so much to people and nations around the world, and despite its destruction in 1989, the memory of its significance endures to this day. Half a century after its construction, what meaning does the Berlin Wall hold for us? Two Princeton University Press authors examine this question in different lights.

In Driving the Soviets up the Wall: Soviet-East German Relations, 1953-1961, Hope M. Harrison examines the Wall as a symbol of the Cold War, telling “the behind-the-scenes story of the communists’ decision to build the Wall in 1961.” Her book explores the relationships between nations within the Soviet bloc as they dealt with the issues of immigration and liberalization. Her narrative provides new insights into how the Wall was viewed by Soviets, and how the initial decision to build the wall was reached.

Mary Elise Sarotte’s 1989: The Struggle to Create Post-Cold War Europe takes a look at the tumultuous period following the fall of the Berlin Wall. Her book tries to understand how various pressures affected the development of the post-1989 world, and how the events of 1989 affected and continue to affect our world today.

Both authors present pictures of the Berlin Wall in ways that ask us to redefine its importance in our lives. The Cold War was a major defining aspect of the United States’ identity in the last century, and its legacy continues to affect America today. With the 50th anniversary of the Wall’s construction upon us, it is worth while to take time to reflect on the Wall, the War, and the vast changes in the world from 1961, to 1989, to the present day.

Taking Heart, Making Art

As a mathematician, I expect that people at parties will tell me that they’re no good at math. I’m used to my friends confessing their fears of my subject. I understand that many people think math is hard and scary. That’s why I was so eager to do something easy and approachable, like drawing, in my math classes. I figured Viewpoints: Mathematical Perspective and Fractal Geometry in Art would allow my students to learn geometry by doing art.

But to my great surprise, I found that it is the art, not the math, that makes people really nervous. As my coauthor Marc Frantz told me, most college graduates have a bit of math in college, and almost all have had a math class their senior year of high school. But few adults have had an art class since 6th grade. Sid’s drawing below is typical of what I see at the beginning of the semester in my course. My students enter college drawing like children, and they are understandably embarrassed by this.

Sid’s first drawing

Learning the mathematical “rules” for drawing opens up whole new possibilities. In this context, rules don’t stifle creativity; they allow for fuller expression. My math-and-art students flourished, and I was heartened, too. Few of my students ever want to see their final calculus exam after they turn it in, but almost all of my students show their parents photocopies they’ve made of the final drawings they’ve turned in to me. Sid’s final drawing, like so much of my students’ late-semester work, shows a mastery of space with hints of great things beyond the horizon. You can tell he’s not going to be afraid of anything.
