Описание: This book develops a dynamical model of the orbital motion of Lorentz spacecraft in both unperturbed and J2-perturbed environments. It explicitly discusses three kinds of typical space missions involving relative orbital control: spacecraft hovering, rendezvous, and formation flying. Subsequently, it puts forward designs for both open-loop and closed-loop control schemes propelled or augmented by the geomagnetic Lorentz force. These control schemes are entirely novel and represent a significantly departure from previous approaches.
Описание: This 1815 pamphlet describes (from written sources) the state of provision for beggars and the sick in Italy, Germany, France, Russia and Iceland, before turning to the history of poor laws in Britain. It concludes that all people in comfortable circumstances should aid the `worthy` poor via existing charitable establishments.
Описание: Contrary to common intuition that all digits should occur randomly with equal chances in real data, empirical examinations consistently show that not all digits are created equal, but rather that low digits such as {1, 2, 3} occur much more frequently than high digits such as {7, 8, 9} in almost all data types
Описание: Clergyman, schoolmaster and writer on aesthetics, William Gilpin (1724-1804) published a series of works recording his observations on the picturesque across British landscapes. This two-volume work of 1789 describes a journey made principally through Scotland in 1776, taking in Edinburgh and the lochs, castles and rivers of the Highlands.

Описание: Frustrated by what he saw as the over-grooming prevalent in British landscape gardening and associated with the work of Capability Brown, Uvedale Price (1747-1829) published this essay in 1794. He emphasises here the importance of naturalism and harmony with the surrounding environment.
