Minerals existed long before any forms of life, playing a key role in the origin and evolution of life; an interaction with biological systems that we are only now beginning to understand. Exploring the traditional strand of mineralogy, which emphasises the important mineral families, the well-established analytical methods (optical microscopy and X-ray diffraction) and the dramatic developments made in techniques over recent decades, David Vaughan also introduces the modern strand of mineralogy, which explores the role minerals play in the plate tectonic cycle and how they interact with the living world. Demonstrating how minerals can be critical for human health and illness by providing essential nutrients and releasing poisons, Vaughan explores the multitude of ways in which minerals have aided our understanding of the world.ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area.

International diplomacy has stopped working. A new breed of authoritarian ruler has emerged, contemptuous of the rules of diplomacy and collective security, and willing to lie and bully to build power and influence. Europe’s democracies are confused and defensive. It is 1938 and Germany is putting pressure on Czechoslovakia.

Merce Cunningham reached the age of 75 in 1994, an age at which many creative artists are content to rest on their laurels, or at least to leave behind whatever controversies they may have caused during their careers. No so Cunningham. In the first place, his 70s have been a time of intense creativity in which he has choreographed as many as four new works a year. Cunningham is a strongly committed as ever to the discovery of new ways of moving and of making movement, refusing to be hampered by the physical limitations that have come with age. Since 1991 every new work has been made at least in part with the use of the computer program Life Forms, which enables him to devise choreographic phrases that he himself would be unable to perform - and which challenge and develop the virtuosity of the young dancers in his company.The essays collected in this special issue of Choreography and Dance were written over the last few years and discuss various aspects of the work of Cunningham as seen both from the outside and the inside.

Apostle of Liberty: The World-Changing Leadership of George Washington' is a biography of the great man, but in truth it is more than a mere biography. It also looks at his unique personal qualities as a leader and how these qualities marked him as a leader among leaders. In doing so, it reveals a man whose greatness did not stem from oratorical skills, superior knowledge, or brilliant military tactics, but from virtue. He understood his duty and his proper role in the fledgling nation, and he pursued it with an invincible resolution. Largely, this was due to his belief that God in his providence had chosen him to lead the new nation that was founded on liberty?civil, religious, and economic?and that the experiment that began under his leadership as president of the Constitutional Convention and was successful under his leadership in battle would prosper under his leadership and change the world if given the opportunity to succeed.

Johann Sebastian Bach was a musical genius, an intellectual giant and a gracious man. His achievement in the area of music is one of the greatest tours de force in history - on a par with or surpassing that of Shakespeare, Michelangelo, Dante, Rembrandt, or Aquinas. Bach worked at a crucial time in history. He combated the ideas of the Enlightenment with its elevation of human reason as the ultimate authority of everything. His struggles, musically and professionally, are those of a man seeking to maintain a high view of worship, academics, and the grounding of all life on the Word of God. As a man valiant in his convictions, he stood against the trends and fashions of his day and succeeded as a witness of the Gospel to the generations who followed him. While his name conjures many images, musical phrases, and half-remembered stories, the life of this colossal genius provides practical lessons in leadership for both artists and anyone who strives to serve others with excellence and integrity.
