Using concepts from algebra and relating them to life, Tess navigates the waters of friendship, popularity, and family. Math lover Tess has always used mathematical concepts to help her understand things in her life. She is surprised to find out how much math—and life—can change in eighth grade. She also has to learn about injustice and ethics when a family friend mysteriously dies, and when she witnesses a cheating episode at her school and realizes that keeping silent about it, even to get in the good graces of the cutest boy in school, only leads to more trouble. Are theorems and axioms about life fail-safe? Is there an absolute answer to everything, just as there are absolute numbers? In the end, Tess decides that her life, like the infinity sign, is always changing, but that as long as she sticks to some key principles for herself, she can handle life’s uncertainties.

In this follow-up to Do the Math: Secrets, Lies, and Algebra, Tess learns that life, like algebra, sometimes has no solutions. Sometimes you just have to take a risk and figure out your own answers. The spring semester of eighth grade, like algebra, has become even more complicated for math-lover Tess. There’s the new girl at school, whom Tess is not quite sure is a friend. There’s bully Richard, who keeps playing mean pranks on her—but if she tells on him, he can finally call her a snitch, so she’s not sure she should. There’s mysterious graffiti on the wall that seems to be a math code. Is it meant for Tess to understand? Could it have anything to do with the fire set in evil Mr. Z’s classroom? Finally, Damien seems to be hanging around more than ever, but she’s not sure why— is it because he likes her, or is it just a “coincidental system” like the one she learned about in algebra class? In the end, Tess figures out that sometimes life doesn’t offer formulas to figuring out the answers. Sometimes you have to take a risk and create your own formulas and discover your own solutions, even if you make a few mistakes along the way.

From the winner of the Turing Award and the Abel Prize, an introduction to computational complexity theory, its connections and interactions with mathematics, and its central role in the natural and social sciences, technology, and philosophy Mathematics and Computation provides a broad, conceptual overview of computational complexity theory—the mathematical study of efficient computation. With important practical applications to computer science and industry, computational complexity theory has evolved into a highly interdisciplinary field, with strong links to most mathematical areas and to a growing number of scientific endeavors. Avi Wigderson takes a sweeping survey of complexity theory, emphasizing the field’s insights and challenges. He explains the ideas and motivations leading to key models, notions, and results. In particular, he looks at algorithms and complexity, computations and proofs, randomness and interaction, quantum and arithmetic computation, and cryptography and learning, all as parts of a cohesive whole with numerous cross-influences. Wigderson illustrates the immense breadth of the field, its beauty and richness, and its diverse and growing interactions with other areas of mathematics. He ends with a comprehensive look at the theory of computation, its methodology and aspirations, and the unique and fundamental ways in which it has shaped and will further shape science, technology, and society. For further reading, an extensive bibliography is provided for all topics covered. Mathematics and Computation is useful for undergraduate and graduate students in mathematics, computer science, and related fields, as well as researchers and teachers in these fields. Many parts require little background, and serve as an invitation to newcomers seeking an introduction to the theory of computation. Comprehensive coverage of computational complexity theory, and beyond High-level, intuitive exposition, which brings conceptual clarity to this central and dynamic scientific discipline Historical accounts of the evolution and motivations of central concepts and models A broad view of the theory of computation's influence on science, technology, and society Extensive bibliography
