Untold story of the World Cup career of Roberto Baggio – one of the most famous names in football.The attacking maestro was a one-of-a-kind genius for the seven Italian clubs he played for across 20 remarkable years. But it was on the world stage, while playing for Italy, that the Baggio legend was born.The first English-language book to examine Baggio’s Italy career across his three World Cups, this riveting tome:Covers each match in which Baggio played in World Cup Italia 1990, USA 1994 and France 1998 Uncovers the stories surrounding the ‘Divine Ponytail’ in the season leading up to each World CupReveals how Baggio came very close to playing in a fourth World Cup in 2002Draws on the expertise of Italian football writers Giancarlo Rinaldi and Richard Hall, who provide exclusive insightThrough three unforgettable tournaments, Baggio crafted some of the most iconic moments in World Cup history. Mark Gordon bring you the definitive account of the player and his World Cup story, showing why – to this day – he still tops fan lists of favourite players.

Recombination lines at radio wavelengths have been - and still are - a pow­ erful tool for modern astronomy. For more than thirty years they have allowed astronomers to probe the gases from which stars form. They have even been detected in the Sun. In addition, observations of these spectral lines facilitate basic research into the atom, in forms and environments that can only exist in the huge dimensions and extreme conditions of cosmic laboratories. We intend this book to serve as a tourist's guide to the world of Radio Recombination Lines. It contains three divisions: a history of their discovery, the physics of how they form and how their voyage to us influences their spectral profiles, and a description of their many astronomical contributions to date. The appendix includes supplementary calculations that may be useful to some astronomers. This material also includes tables of line frequencies from 12 MHz to 30THz (AlOJLm) as well as FORTRAN computer code to calculate the fine structure components of the lines, to evaluate radial matrix integrals, and to calculate the departure coefficients of hydrogen in a cosmic environment. It also describes how to convert observational to astrophysical units. The text includes extensive references to the literature to assist readers who want more details.
