The book starts with a review of the established facts on the numerical simulations of binary neutron star mergers and simulations of short GRB jets that highlights the issues that need to be revised and further clarified, as the need to understand how the relativistic outflow was launched, what the initial structure of the outflow is, and how it evolved through its interaction with the binary ejecta. Constraints on a local population of faint short duration GRBs are then provided in light of the GW170817/GRB 170817A event at d~40 Mpc by considering statistical limits on a d < 200 Mpc population. Using past and current GRB detectors, results suggest that GRB 170817A-like events are likely to...
This is a book about the land wars Pennsylvania found itself embroiled in during the latter half of the 18th Century. The wars stemmed from the ambiguous Charters that established the the Colonies of Pennsylvania, Connecticut, and Virginia. Charles II created the conflict between Pennsylvania and Connecticut by the overlapping of the boundaries of the land he granted to each colony. Similarly, the land granted to Pennsylvania was contested by Virginia. But Virginia could have contested nearly any Colony's land grant. Virginia's grant from James I included most of present-day United States, northern Mexico, and most of western Canada. These armed conflicts were settled only by the first Congress established by the newly formed United States Constitution in 1787, when it ruled in Pennsylvania's favor.This book is purchased at the lowest cost through Lulu.com.
What existential threats does humanity face? And how can we secure our future? 'The Precipice is a powerful book . . . Ord's love for humanity and hope for its future is infectious' Spectator 'Ord's analysis of the science is exemplary . . . Thrillingly written' Sunday Times We live during the most important era of human history. In the twentieth century, we developed the means to destroy ourselves – without developing the moral framework to ensure we won't. This is the Precipice, and how we respond to it will be the most crucial decision of our time. Oxford moral philosopher Toby Ord explores the risks to humanity's future, from the familiar man-made threats of climate change and nuclear ...
