The book presents an advanced but accessible overview of some of the most important sub-branches of magnetohydrodynamics (MHD): stability theory, magnetic topology, relaxation theory and magnetic reconnection. Although each of these subjects is often treated separately, in practical MHD applications they are normally inseparable. MHD is a highly active field of research.The book is written for advanced undergraduates, postgraduates and researchers working on MHD-related research in plasma physics and fluid dynamics.

"For this brief moment, the two sisters could be 'together in heart and affection', and through such letters bridge the distance of empire." We often learn about the commerce, diplomacy, and military campaigns of the British empire without reference to the intimate side of life in these times-the development of self, the position of women, and the importance of family. In this book, the story of empire, so often told from a man's perspective, is given a unique vantage point through Eliza Hillier's letters to her younger sister, Martha. Written largely from Hong Kong, Shanghai, England, and Siam, the letters allow us to become a member of her family and follow the daily tribulations associated with the life of a young British woman in the port cities of Asia. We are thus able to share Eliza's experiences as she leaves home to embark on married life, starts and raises a family, grieves at the abrupt and tragic loss of her husband, Charles Batten Hillier, and then sets about re-building her life. At once a reflection on the daily components of empire, an entertaining narrative of familial relationships, and the story of one woman's inner feelings, My Dearest Martha guides us through the vagaries of life for a family who were very much a part of imperial careering and missionary circles in East and Southeast Asia. The letters are complemented by images and commentary from the author, a descendant of Eliza, providing context and depth, which together give us a fuller picture of British colonial life in the mid-1800s from a perspective that will resonate with readers around the world.
