A FASCINATING INVESTIGATION OF HOW WE NAVIGATE THE PHYSICAL WORLD, INNER NAVIGATION IS A LIVELY, ENGAGING ACCOUNT OF SUBCONSCIOUS MAPMAKING. Why are we so often disoriented when we come up from the subway? Do we really walk in circles when we lose our bearings in the wilderness? How -- and why -- do we get lost at all? In this surprising, stimulating book, Erik Jonsson, a Swedish-born engineer who has spent a lifetime exploring navigation over every terrain, from the crowded cities of Europe to the emptiness of the desert, gives readers extraordinary new insights into the human way-finding system. Written for the nonscientist, Inner Navigation explains the astonishing array of physical and psychological cues the brain uses to situate us in space and build its "cognitive maps" -- the subconscious maps it employs to organize landmarks. Humans, Jonsson explains, also possess an intuitive direction frame -- an internal compass -- that keeps these maps oriented (when it functions properly) and a dead-reckoning system that constantly updates our location on the map as we move through the world. Even the most cynical city-dweller will be amazed to learn how much of this innate sense we use every day as we travel across town or around the world. Both a scientific and a human story, Inner Navigation contains a rich assortment of real-life insights and examples of the navigational challenges we all face, no matter where or how we live. It's a book that is as provocative to ponder as it is delightful to lose yourself in. Don't worry: Erik Jonsson will help you find your bearings.

The 5th century AD barge of Santa Maria in Padovetere was discovered and investigated inside an ancient river, West of Comacchio. The place, which later hosted the parish of Santa Maria in Padovetere, is considered a strategic crossroads of Late Roman waterways. The anoxic conditions have well preserved the bottom and the entire right side. This extraordinary conservation, coupled with in situ digital documentation, has allowed the reconstruction in 3D of the entire shape of the shipwreck. It was a riverine flat bottom barge with a very high stern and a central long rudder according to a shipshape well documented by Central European Roman sculptures. Scientific analysis allowed to reconstruct the environment where it moved and to make hypotheses on the types of goods transported. This is a very rare example of an ancient riverine barge and an important evidence of the technique of construction by sewing. The book also presents other recent finds of this construction technique which, during the Roman period and the Early Middle Age, was used only in the Upper Adriatic.
