The Barefoot Navigator is an unusual and fascinating exploration of the skills of navigation employed by the ancients and transferrable to the present day. The first half of the book investigates the navigation capabilities of seafarers long before modern navigation instruments or charts became available. For example, how did the Polynesians manage to populate an area of ocean larger than North America simply by analysing clouds, currents, wind direction, sun, stars and the flight patterns of ocean birds? And how did the Vikings routinely travel between Iceland, Greenland and Scandinavia - huge tracts of treacherous water? The second part of the book analyses how the techniques of the ancients can be employed by 21st century seafarers to supplement today's navigational hardware - especially in survival situations. This is a unique analysis of practical technology-free navigation, whose techniques can easily be employed by modern navigators to supplement their personal navigation skills in order to just 'know' where they are. It will fascinate navigators and landlubbers alike.

Earth is one small speak among billions of stars, planets, and moons. So how can we figure out where it is in the universe? The answer is sky maps and charts! Maps can tell us where Earth is located in the huge star system we call the Milky Way galaxy. Charts can help us explore other planets and the Moon. They can even help us study the stars. Begin your adventure as an astronomer by using maps and star charts to learn about what you can see in the night sky-and what you can't see! Book jacket.

In this encyclopedic book, Lewis provides insights into the origins, training, tactics, weapons and achievements of special forces and special mission units throughout the world, focusing particularly on US and UK forces. He also looks at the codes that that bind the members of these elite units together. He reveals training secrets in everything from wilderness survival to hand-to-hand combat. In doing so, he draws extensively on biographies, autobiographies, training manuals, interviews and press coverage of key operations. The elite forces covered include: The British Army's Special Air Service (SAS), established in 1950, which has served as a model for the special forces of many countries. Its counter-terrorist wing famously took part in the hostage rescue during the siege of the Iranian Embassy in London in 1980. The Parachute Regiment, the airborne infantry element of 16 Air Assault Brigade, which spearheads the British Army's rapid intervention capability. It is closely linked to United Kingdom Special Forces. The US Navy's SEALS (Sea, Air, Land Teams), trained to conduct special operations in any environment, but uniquely specialised and equipped to operate from and in the sea. Together with speedboat-operating Naval Special Warfare Combatant-Craft Crewmen, they form the operational arm of the Naval Special Warfare community, the Navy component of the US Special Operations Command. Their special operations include: neutralizing enemy forces; reconnaissance; counter-terrorism (famously in the killing of Osama bin Laden); and training allies. The US Army's Delta Force: The Special Mission Unit, 1st Special Forces Operational Detachment-Delta (1st SFOD-D), known simply as Delta Force, the Army component of Joint Special Operations Command. Its role is counter-terrorism, direct action and national intervention operations, though it has the capability to conduct many different kinds of clandestine missions, including hostage rescues and raids. The US Army Rangers, a light infantry combat formation under the US Army Special Operation Command. The Green Berets - motto: 'to free the oppressed' - trained in languages, culture, diplomacy, psychological warfare and disinformation. Russia's Spetsnaz, whose crack anti-terrorist commandos ended the Moscow theatre siege, and who have a reputation for being among the world's toughest and most ruthless soldiers. Spetsnaz units saw extensive action in Afghanistan and Chechnya, often operating far behind enemy lines. Israeli Special Forces, especially Shayetet 13 (Flotilla 13), whose motto, in common with the rest of the Israeli military, is 'Never again', a reference to the Holocaust. They are particularly adept at the specifically Israeli martial art Krav Maga, which they dub 'Jew-jitsu'.
