In 1937, Roger Penrose and his father discovered a sundial in a clearing behind their house in Colchester. In that machine made of light, shadow and time, six-year-old Roger discovered a world behind the world of transcendently beautiful geometry. He had begun a journey that would make him one of the past centurys most influential mathematicians, philosophers and physicists. He received a Nobel Prize, a knighthood and dozens of other prestigious honours. He proved the limitations of general relativity and set a new agenda for theoretical physics. But success came at a price as he struggled to connect with friends, family and especially the women in his life. He has spent his final years alone with his research, intentionally cut off from the people who loved him. Compelling and deeply moving, The Impossible Man intimately depicts the relationship between Penrose the scientist and Roger the human being. It reveals the tragic cost - to himself and those closest to him - for his extraordinary life.

L.T.C. Rolt is still a towering figure in the fields of inland waterways, preserved railways and post-war conservation. A bridge and a locomotive have been named after him, and there is a Rolt Prize, Rolt Fellows and an annual Rolt Lecture. He played a crucial role in the revival of Britains inland waterways and pioneered the first preserved narrow-gauge railway. In this fascinating series of linked essays, Joseph Boughey explains aspects of Rolts earlier life and work, and sets his writing and practice in a broader context, considering such themes as the landscapes Rolt knew; the nature of travel and country writing; the 1930s/40s organicist movement; English canals and navigable rivers from the 1930s to the 50s, including practical campaigning; the background to early railway preservation; and the nature of craft, craftspeople and preservation.
