Summary

In the long-awaited follow-up to the #1 bestselling thriller INVISIBLE . . . the perfect murder always looks like an accident. FBI agent Emmy Dockery is absolutely relentless. She's young and driven, and her unique skill at seeing connections others miss has brought her an impressive string of arrests. But a shocking new case-unfolding across the country-has left her utterly baffled. The victims all appear to have died by accident, and have seemingly nothing in common. But this many deaths can't be coincidence. And the killer is somehow one step ahead of every move Dockery makes. How? To FBI special agent Harrison "Books" Bookman, everyone in the FBI is a suspect-particularly Emmy Dockery (the fact that she's his ex-fiancee doesn't make it easier). But someone else is watching Dockery. Studying, learning, waiting. Until it's the perfect time to strike.

Summary

Mathematicians and non-mathematicians alike have long been fascinated by geometrical problems, particularly those that are intuitive in the sense of being easy to state, perhaps with the aid of a simple diagram. Each section in the book describes a problem or a group of related problems. Usually the problems are capable of generalization of variation in many directions. The book can be appreciated at many levels and is intended for everyone from amateurs to research mathematicians.

Summary

Despite advances in DNA testing, forensics, and the investigative skills used by police, hundreds of crimes remain unsolved across Canada. With every passing day trails grow colder and decades can pass before a new lead or witness comes forward if one comes forward. In Unsolved, Robert J. Hoshowsky examines twelve crimes that continue to haunt us. Some cases are well-known, while others have virtually disappeared from the public eye. All of the cases remain open, and many are being re-examined by police using the latest tools and technology. Hoshowsky takes the reader through all aspects of the crimes and how police are trying to solve them using three-dimensional facial reconstructions, DNA testing, age-enhanced drawings, original crime scene photos, and more. None of the individuals profiled in Unsolved deserved their fate, but their stories deserve to be told and their killers need to be brought to justice.

Summary

Solved and Unsolved Problems of Structural Chemistry introduces new methods and approaches for solving problems related to molecular structure. It includes numerous subjects such as aromaticity—one of the central themes of chemistry—and topics from bioinformatics such as graphical and numerical characterization of DNA, proteins, and proteomes. It also outlines the construction of novel tools using techniques from discrete mathematics, particularly graph theory, which allowed problems to be solved that many had considered unsolvable. The book discusses a number of important problems in chemistry that have not been fully understood or fully appreciated, such as the notion of aromaticity and conjugated circuits, the generalized Hückel 4n + 2 Rule, and the nature of quantitative structure–property–activity relationships (QSARs), which have resulted in only partially solved problems and approximated solutions that are inadequate. It also describes advantages of mathematical descriptors in QSAR, including their use in screening combinatorial libraries to search for structures with high similarity to the target compounds. Selected problems that this book addresses include: Multiple regression analysis (MRA) Insufficient use of partial ordering in chemistry The role of Kekulé valence structures The problem of protein and DNA alignment Solved and Unsolved Problems of Structural Chemistry collects results that were once scattered in scientific literature into a thoughtful and compact volume. It sheds light on numerous problems in chemistry, including ones that appeared to have been solved but were actually only partially solved. Most importantly, it shows more complete solutions as well as methods and approaches that can lead to actualization of further solutions to problems in chemistry.

Law enforcements, both local and federal, estimate that there are between 35 and 50 serial killers on the loose and active in the United States alone. Some even put the number closer in the hundreds. In any case, officials anticipate these numbers to continue rising. Knowing that there is someone stalking the streets that you live on, looking for victims, is very scary.

Summary

Down comes a deluge of sonorous hail, Or prone-descending rain. Wide-rent, the clouds Pour a whole flood, and yet, its flame unquenched, Th’unconquerable lightning struggles through. Ragged and fierce, or in red whirling balls, And fires the mountains with redoubled rage. Black from the stroke, above, the smould’ring pine Stands a sad shattered trunk; and, stretched below, A lifeless group the blasted cattle lie. James Thompson, “The Seasons” (1727) have been investigating ball lightning for more than two decades. I published a ball lightning report in Nature in 1976 that received worldwide publicity and I consequently many people wrote to me with accounts of their own experiences. Within a very short time, I had accumulated about 200 firsthand accounts, and the file has continued to grow steadily since then. Several things impressed me. Few of those who wrote to me had any detailed foreknowledge of ball lightning at the time of their observation. Nonetheless, once reports of other phenomena such as St. Elmo’s fire had been eliminated, the remaining descriptions were remarkably consistent. Furthermore, nearly all who contacted me were keen to have an explanation of what they had seen and seemed entirely sincere.

Summary

Each year, hundreds of thousands of people are reported missing in the United States alone. The majority of those who disappear turn up within a week, but a small percentage are never heard from again. Why did a Swedish teenager on an Australian adventure mail a cryptic letter to his family in Stockholm before disappearing forever? What became of a young woman whose car was found crashed and abandoned off a cliffside in Whatcom County, Washington? How can an individual vanish without a trace in a world so connected and monitored? This book explores ten unsolved missing persons cases from around the world, from a 12-year-old British boy who purchased a one-way ticket to London King's Cross never to return, to an American traveler who walked into the Himalayas not to be seen again. Included are exclusive interviews, statistical information and a case-by-case analysis of the most common and probable theories for each disappearance.
