At some point, everyone living in the United States has some type of interaction with the American judicial system. For most, this contact is relatively minor: contesting a traffic ticket, suing or being sued in civil court, being a witness in a civil or criminal trial, or serving on a jury. Others are caught up in the criminal justice system - as defendants, as victims, as witnesses, as jurors, or as relatives of a victim or a defendant. For still others, contact comes via an important policy issue affecting their lives in the hands of judges and justices sitting in judgment in marble temples to the law. Yet whatever the level of contact, the American judicial system affects peoples' lives. What courts and judges do matters.

Volcanoes are some of the most dramatic expressions of the powerful tectonic forces at work in the Earth beneath our feet. But volcanism, a profoundly important feature of Earth, and indeed of other planets and moons too, encompasses much more than just volcanoes themselves. On a planetary scale, volcanism is an indispensable heat release mechanism, which on Earth allows the conditions for life. IIt releases gases into the atmosphere and produces enormous volumes of rock, and spectacular landscapes - landscapes which, during major eruptions, can be completely reshaped in a matter of hours. Through geological time volcanism has shaped both climate and biological evolution, and volcanoes can affect human life, too, for both good and ill. Yet, even after much study, some of the fundamental aspects of volcanicity remain mysterious.
