The Space Shuttle is one of the oldest and most famous manned launch systems – the only launch vehicle that has been used for a longer period of time is the Soviet (now Russian) R-7 booster. By the start of the third millennium, the Space Shuttle had carried crews into space over 85 times. Although not a military structure, the Shuttle had been sold as an all-purpose launch system to be used jointly for military and civilian purposes. Featuring full-colour photos throughout, this book covers the design, development and operational history of a unique vehicle.

The US Army requirement for a light utility helicopter was formulated after the Korean War. Bell's Model 204 design won a competition in 1955, and was given the military designation H-40, later renamed the HU-1 Iroquois. The original design called for a helicopter that could be used for transport, airborne battlefield command and control, medical evacuation, fire support co-ordination and search and rescue. Later its missions would be expanded to include troop insertion/extraction, armed escort and special operations. This title details all the technological background behind the development and use of the Huey “Slick” in Vietnam, as well as covering all the major uses that this transport aircraft was put to.

Entering service in the early 1960s, the M60 tank was in production for 23 years and formed the backbone of US Army and Marine armoured units during the Cold War. Over 15,000 were built in four basic models: the M60, M60A1, M60A2, and the M60A3. Although the M60 had been phased out of US Army service by the time Iraq invaded Kuwait in 1990, M60s were amongst the first Allied tanks to enter Kuwait City with the US Marines. This book examines the design and deployment of the M60, a very widely used vehicle that is still in service today.

Noriko is just getting started as a junior reporter for the Asagake Times. She wants to cover the hard-hitting issues, like world affairs and politics, but does she have the smarts for it? Thankfully, her overbearing and math-minded boss, Mr. Seki, is here to teach her how to analyze her stories with a mathematical eye. In The Manga Guide to Calculus, you'll follow along with Noriko as she learns that calculus is more than just a class designed to weed out would-be science majors. You'll see that calculus is a useful way to understand the patterns in physics, economics, and the world around us, with help from real-world examples like probability, supply and demand curves, the economics of pollution, and the density of Shochu (a Japanese liquor). Mr. Seki teaches Noriko how to: Use differentiation to understand a function's rate of change Apply the fundamental theorem of calculus, and grasp the relationship between a function's derivative and its integral Integrate and differentiate trigonometric and other complicated functions Use multivariate calculus and partial differentiation to deal with tricky functions Use Taylor Expansions to accurately imitate difficult functions with polynomials Whether you're struggling through a calculus course for the first time or you just need a painless refresher, you'll find what you're looking for in The Manga Guide to Calculus. This EduManga book is a translation from a bestselling series in Japan, co-published with Ohmsha, Ltd. of Tokyo, Japan.

For thousands of years organized naval warfare was the exclusive preserve of the galley. Oars provided a level of control and maneuverabilty beyond the capabilities of the contemporary sailing ship, and not experienced again until the era of the screw propeller. Precise control allowed squadrons and fleets to operate together, as a unit, which promoted the evolution of earlier fighting tactics. However, for fleets to be more effective than collections of individual vessels, they needed training and organization, from which the first state-funded navies were to develop. THE AGE OF THE GALLEY charts this development from the earliest paleolitic crafts, some of which were paddled rather than rowed, to the classical trireme and its Roman and Byzantine successors. However, as a warship, the galley survived the coming of the three-masted sailing ship and even adapted itself to gunpowder artillery, so later chapters are devoted to the medieval and Renaissance fleets that served the later maritime powers in the Mediterranean. The principal historical chapters are backed by more general sections on the design and oar system of galleys, on the organization and infrastructure of galley fleets, and on non-military applications of the galley. With the recent trials of the Greek Navy's reconstructed trireme, this volume has been able to take advantage of much new research; the upsurge in interest in these crafts makes the publication of this work particularly welcome. Lavishly illustrated, THE AGE OF THE GALLEY includes over 65 black-and-white photos, over 200 illustrations and 15 tables.

This book is a great way to learn some of the interesting aspects of numbers. Among some of the subjects covered include numbering systems, ciphers, angles, dimensions, and of course, algebra. This book is designed to make mathematics interesting. The science is not treated formally; abstract conceptions and uninteresting and abstruse procedures are completely avoided; yet at the same time the book is sufficiently complete so as to give a broad picture of mathematical fundamentals. Mathematics, in order to be appreciated by those who do not have a flare for the intangible must be seen in the light of its versatility in the various fields of human endeavor. This is very much the central theme of this book.

This is a collection of informative extracts from Gardners' "Scientific American" column. Each brain-teasing article has been updated to include new mists, new ideas, and new solutions. Highlights include two new chapters-one on pi and poetry, one on minimal sculpture - and intriguing forays into time reversal, forms of fractions and magic, and an imaginary "Math Zoo" with its own publication, "ZOO-NOOZ".

The catapult (katapeltikon) was invented under the patronage of Dionysius I, tyrant of Syracuse, in the 4th century bc. At first only the arrow-firing variant was used, and it was not until the reign of Alexander the Great that stone-projecting catapults were introduced. The Romans adopted these weapons during the Punic Wars and further developed them, before introducing the new arrow-firing ballista and stone-throwing onager. This title traces the often controversial design, development and construction of these weapons throughout the history of the classical world.

Entering service in the early 1960s, the M109 Self-Propelled Howitzer has been in production for 34 years and forms the backbone of US Army and Reserve artillery units. The M109A6 is the latest development of the M109 series and incorporates advanced fire control systems that enable it to have its first rounds on target less than 60 seconds after arriving at firing location. This ability to shift quickly between moving and firing modes avoids counter battery fire and ensures battlefield survivability. This book details an impressive and versatile weapon that has served around the globe in Southeast Asia and in Operations Desert Shield and Desert Storm.
