String theory is a model of fundamental physics whose building blocks are one-dimensional extended objects called strings, rather than the zero-dimensional point particles that form the basis for the standard model of particle physics. The phrase is often used as shorthand for Superstring theory, as well as related theories such as M-theory. By replacing the point-like particles with strings, an apparently consistent quantum theory of gravity emerges. Moreover, it may be possible to 'unify' the known natural forces (gravitational, electromagnetic, weak nuclear and strong nuclear) by describing them with the same set of equations. Studies of string theory have revealed that it predicts higher-dimensional objects called branes. String theory strongly suggests the existence of ten or eleven (in M-theory) space-time dimensions, as opposed to the usual four (three spatial and one temporal) used in relativity theory.

Recent experimental results with direct bearing on theories of cosmological dark matter/energy, as well as continuing work on neutrino masses and mixing, have invigorated both particle physics and cosmology, and should continue to do so well into the 21st century, thereby launching a beautiful new epoch for these fields. The expert contributions from this conference took stock of these developments. This volume contains papers by over 40 physicists that summarize and interpret the newest findings, and suggest future avenues to be explored. A number of new theoretical ideas are also presented, dealing with progress in understanding the dynamics and symmetries of strings and branes, renormalization in quantum field theory, possible Lorentz violation effects, and related problems. Ongoing and next generation gravitational and neutrino experiments are described, and the issues of unification are dealt with in the context of, and beyond, the standard model. Together, the contributions provide a useful blend of experimental and theoretical physics from many prominent physicists, including three Nobel Laureates. The volume also contains information of an historical nature, concerning the contributions to physics by Paul Frampton, on the occasion of his 60th year, and summarizing the career of Behram Kursunoglu (1922-2003).

Political parties, interest groups, and candidate campaigns all pursue similar goals in presidential elections: each entity attempts to mobilize voters. However, the regulatory environment often prevents these groups from coordinating their efforts. With participants playing by new rules mandated by the Bipartisan Campaign Reform Act, the 2004 presidential election included previously unseen configurations and alliances between political actors. In some campaign situations, the resulting 'dance' was carefully choreographed. In others, dancers stepped on each other's toes. In still others, participants could only eye each other across the floor. Dancing without Partners intensively analyzes the relationships among candidates, political parties, and interest groups under the BCRA's new regulations in the 2004 election cycle in five battleground states. The chapters assess the ways in which the rules of the game have changed the game itself_and also how they haven't. The result is a book that will be invaluable to researchers and students of presidential elections.

In a land occupied for thousands of years, mystery and unrest linger. Anguished soldierly figures dot the landscape of Pasco County, from the doomed march of Major Dade and his haunted hill to the ghost of Captain Jeffries standing watch over his homestead in Zephyrhills. A pair of spirits drifts about near a Dade City pond, perhaps the brother and sister cut down during the infamous Bradley Massacre. Echoes of the once rugged frontier rebound from the Ellis-Gillett feud, vigilantism and Sheriff Bart's justice. Obliterating the mounds of indigenous people cast an ever-present and ominous tone over sacred grounds throughout the county. Author Madonna Wise shares ethereal accounts of the Meighan Theatre, the treacherous Road to Nowhere, the Edwinola Hotel and more.

Physicists argue from different perspectives for and against the idea of the existence of multiple universes.

This journal is devoted to the latest research on physics, publishing articles on everything from elementary particle behavior to black holes and the history of the universe.

An urgent look at the relationship between guns, the police, and race The United States is steeped in guns, gun violence—and gun debates. As arguments rage on, one issue has largely been overlooked—Americans who support gun control turn to the police as enforcers of their preferred policies, but the police themselves disproportionately support gun rights over gun control. Yet who do the police believe should get gun access? When do they pursue aggressive enforcement of gun laws? And what part does race play in all of this? Policing the Second Amendment unravels the complex relationship between the police, gun violence, and race. Rethinking the terms of the gun debate, Jennifer Carlson shows how the politics of guns cannot be understood—or changed—without considering how the racial politics of crime affect police attitudes about guns. Drawing on local and national newspapers, interviews with close to eighty police chiefs, and a rare look at gun licensing processes, Carlson explores the ways police talk about guns, and how firearms are regulated in different parts of the country. Examining how organizations such as the National Rifle Association have influenced police perspectives, she describes a troubling paradox of guns today—while color-blind laws grant civilians unprecedented rights to own, carry, and use guns, people of color face an all-too-visible system of gun criminalization. This racialized framework—undergirding who is “a good guy with a gun” versus “a bad guy with a gun”—informs and justifies how police understand and pursue public safety. Policing the Second Amendment demonstrates that the terrain of gun politics must be reevaluated if there is to be any hope of mitigating further tragedies.
