Many of us have been fascinated as children by soap bubbles and soap films. Scientists and mathematicians have been interested in the properties of bubbles and films throughout scientific history.

In Demonstrating Science with Soap Films David Lovett describes how the properties of soap films and bubbles can illustrate and elucidate a wide range of physical principles and scientific phenomena. The book is designed to appeal to both high school and university teachers and lecturers, curious general science readers, and researchers studying soap films and minimal surfaces.

The text is enhanced by
* over 100 diagrams and photographs
* details of practical experiments that can be performed using simple household materials
* computer programs that draw some of the more complicated figures or animate sequences of soap film configurations
* a bibliography for readers wishing to delve further into the subject.

Whilst much of the mathematics employed to explain concepts is at high school level, the more advanced topics are boxed and so may be omitted by readers without the appropriate mathematical background.

In 1995, computer fraud took down England's oldest bank. In 1996, Omega Engineering Company lost over $10 million to one disgruntled employee's computer fraud. In 2001, two Cisco Systems employees stole $8 million in computer stock option refunds through computer fraud. And technology experts and professional crime fighters predict that computer crime will continue to explode in the coming years. Brimming with these and other astonishing real-life case studies written by the ACFE members who investigated them, Computer Fraud Casebook reveals how vulnerable all businesses are to fraud and offers investigation and prevention guidance to stop cyber-thieves in their virtual tracks.

Gone are the days when a small business might lose only a few thousand dollars to fraud. Today, computer fraud costs companies and consumers billions of dollars. In cyberspace, the fraudster has morphed from a hapless rip-off artist into a clever, diabolical techno-thief with the ability to steal and destroy on a grand scale around the world. High-tech criminals can obliterate records, bankrupt companies, steal money, cheat consumers, rob identities, and cause unprecedented havoc, often with a single click of the mouse.

Author Joseph Wells, founder and Chairman of the Association of Certified Fraud Examiners—the world's leading anti-fraud organization—provides readers with an understanding of the scope and complexity of computer crime. Focusing on cases committed in the workplace, Wells introduces the scam methods and techniques that were unheard of just a few years ago. His comprehensive compilation forms a clear picture of the many types of computer fraud out there—including e-mail fraud, online auction fraud, security breaches, and counterfeiting—and how they were investigated across industries and throughout the world. Once fraud occurs, recovering the victim's money is difficult, if not impossible. The forty-two case studies in Computer Fraud Casebook reveal how and why prevention is the number-one goal of theanti-fraud specialist.

From their rise to success through their cunning and diabolical schemes to their eventual capture and downfall, Computer Fraud Casebook is full of amazing stories of the investigators' dedication, skill, and intelligence to uncover fraudsters and put an end to corruption. From these stories, auditors, controllers, IT managers, investigators, law enforcement professionals, fraud examiners, clients, employers, managers, consumers, students—virtually anyone with a computer—will discover a wealth of resources available to snare criminals and, even more importantly, prevent fraud from happening in the first place.

"Whether your primary interest is popular science or pro football, you will enjoy FOOTBALL PHYSICS." (Bill Belichick, head coach, New England Patriots )

"Football Physics is great fun. It taught me more about football than 50 years of watching the game." (Robert K. Adair, Ph.D., author of Physics of Baseball )

"I didn't need physics when I played, but maybe some of these young guys do..." (Chuck Bednarik, Hall of Fame center/linebacker )

"I think we'll be seeing this book in a lot of NFL locker rooms." (Brad Minerd, producer, NFL films )

Do you cringe when a linebacker flattens a quarterback? Hold your breath when a field goal sails toward the goalpost? Watch in amazement as a touchdown pass spirals down the field? Behind those big hits, long kicks, and sensational throws is a science that will give you a whole new perspective on the game of football.

A combination of Stephen Hawking and Mike Ditka, physicist and football fan Timothy Gay breaks down the fundamental laws of physics that govern America's most exciting spectator sport. To illustrate the science behind the game, he highlights some of football's recent memorable moments, along with legendary feats from the likes of Franco Harris and Joe Montana.

Did you Know?

• Newton's Second Law of Physics proves that Dick Butkus hit running backs with the force of a small killer whale.
• The average force with which a football must be kicked during kickoff is 450 lbs. But for an instant, the force may be as much as a ton.
• Shaun Rogers, firing off the line of scrimmage, can develop as much as four horsepower by himself.

This book equips the student with essential intellectual tools that are needed from the very beginning of university studies in computing. These consist of abilities and skills - to pass from a concrete problem to an abstract representation, reason with the abstract structure coherently and usefully, and return with booty to the specific situation. The most basic and useful concepts needed come from the worlds of sets (with also their employment as relations & functions), structures (notably trees & graphs), & combinatorics (alias principles of counting, with their application in the world of probability). Recurring in all these are 2 kinds of instrument of proof - logical (notably inference by suppositions, reductio ad absurdum, & proof by cases), & mathematical (notably induction on the positive integers & on well-founded structures).From this book the student can assimilate the basics of these worlds & set out on the paths of computing with understanding & a platform for further study as needed.

Computer languages and computer graphics have become the primary modes of human-computer interaction. This book provides a basic introduction to "Real and Virtual Environment" computer modelling. Graphics models are used to illustrate both the way computer languages are processed and also used to create computer models of graphic displays. Computer languages have been bootstrapped from machine code, to high-level languages such as Java, to animation scripting languages. Integrating graphic and computer models takes this support for programming, design and simulation work, one step further, allowing interactive computer graphic displays to be used to construct computer models of both real and virtual environment systems. The Java language is used to implement basic algorithms for language translation, and to generate graphic displays. It is also used to simulate the behaviour of a computer system, to explore the way programming and design-simulation environments can be put together.

Practical Formal Software Engineering is a textbook aimed at final year undergraduate and graduate students, emphasizing formal methods in writing robust code quickly. Engineering is an informal process using formal logics as tools and components to obtain timely practical solutions. This book takes an engineering approach to illuminate the creation and verification of large software systems in which theorems and axioms are intuited as the formalism materializes through practice. Where other textbooks discuss business practices through generic project management techniques or detailed rigid logic systems, this book examines the interaction between code in a physical machine and the logic applied in creating the software. These elements create an informal and rigorous study of logic, algebra, and geometry through software. Assuming prior experience with C, C++, or Java programming languages, chapters introduce UML, OCL, and Z from scratch. Based around a theme of the construction of a game engine, extensive worked examples motivate readers to learn the languages through the technical side of software science.
