A veritable rock star in the book world some five centuriesafter his birth, Leonardo Da Vinci is a man for the ages. Millionsof readers hungrily ponder the mysteries behind his sketch-fillednotebooks, radical inventions, and enigmatic paintings. Thisstunning book, like no other on the market, explores the master’sinsights and synthesizes his relationship with art and science in amagnificently illustrated and informative style. Every pageresonates with Leonardo’s genius, demonstrated by his own art andwritings as well as modern diagrams and workable re-creations ofhis inventions. Physicist and artist Bulent Atalay, author of Math and the MonaLisa, deftly explains Leonardo’s interest in topics ranging fromarchitecture to botany to philosophy. Engaging prose and splendidimages point up the science and mathematics underlying Leonardo’sgenius, showing how attention to proportions, patterns, shapes, andsymmetries informed his art. The story flows chronologically, withquotations revealing the near-magical

In his bestselling The Moral Animal, Robert Wright applied theprinciples of evolutionary biology to the study of the human mind.Now Wright attempts something even more ambitious: explaining thedirection of evolution and human history–and discerning wherehistory will lead us next. In Nonzero: The Logic of Human Destiny, Wright asserts that, eversince the primordial ooze, life has followed a basic pattern.Organisms and human societies alike have grown more complex bymastering the challenges of internal cooperation. Wright'snarrative ranges from fossilized bacteria to vampire bats, fromstone-age villages to the World Trade Organization, uncovering suchsurprises as the benefits of barbarian hordes and the usefulstability of feudalism. Here is history endowed with moralsignificance–a way of looking at our biological and culturalevolution that suggests, refreshingly, that human morality hasimproved over time, and that our instinct to discover meaning mayitself serve a higher purpose. Insightful, wi

The ecological literature on marsupials is dominated byde*ive natural history, and there has hitherto been littleattempt at either synthesis or evolutionary interpretation. Thisbook attempts to provide such a synthesis, by drawing on both thede*ive data base and predictions from the burgeoningliterature on behavioural and evolutionary ecology. It documentsthe excellent potential the study of marsupials provides forresolution of theoretical questions of general importance inbiology. It does this in three ways. First, by describing theimpressive diversity of marsupial life history strategies andtrophic roles. Second, by careful comparison with the eutherians,the scope of the marsupial radiation is used to analyse the role ofdevelopmental constraints and adaptive radiation in determining thediversification of higher taxa. Lastly, it is suggested that theaccessibility of marsupial young during their obligatory pouch lifefacilitates measurement, manipulation and assessment of kinship notpossible in other mammalia

There has been an explosive growth in the field ofcombinatorial algorithms. These algorithms depend not only onresults in combinatorics and especially in graph theory, but alsoon the development of new data structures and new techniques foranalyzing algorithms. Four classical problems in networkoptimization are covered in detail, including a development of thedata structures they use and an analysis of their running time.Data Structures and Network Algorithms attempts to provide thereader with both a practical understanding of the algorithms,described to facilitate their easy implementation, and anappreciation of the depth and beauty of the field of graphalgorithms.

How do plant and animal populations change genetically toevolve and adapt to their local environments? How do populationsgrow and interact with one another through competition andpredation? How does behaviour influence ecology and evolution?Introduction to Population Biology covers all these areas and more.Taking a quantitative and Darwinian perspective, the basic theoryof population processes is developed using mathematical models. Toallow students of biology, ecology and evolution to gain a realunderstanding of the subject, key features include: ? step-by-stepinstructions for spreadsheet simulations of many basic equations toexplore the outcomes or predictions of models ? worked examplesshowing how the equations are applied to biological questions ?problem sets together with detailed solutions to help the readertest their understanding ? real-life examples to help the readerrelate the theory to the natural world

Water is everywhere. It covers almost 70 percent of Earth's surface. It forms the oceans and flows as rushing rivers. The atmosphere not to mention clouds is a vast storehouse of water in the form of the gas called water vapor. Billions of tons of water are locked up as the enormous ice caps that sit on the top and bottom of the world. If all of that icy water were to melt, it would cause a rise in sea level of about 260 feet (80 meters). Coastal cities the world over would be flooded beyond repair.
