Paddle Steamer
A paddle steamer is a steamship or steamboat powered by a steam engine driving paddle wheels to propel the craft through the water. In antiquity, paddle wheelers followed the development of poles, oars and sails, whereby the first uses were wheelers driven by animals or humans. In the early 19th century, paddle wheels were the predominant way of propulsion for steam-powered boats. In the late 19th century, paddle propulsion was largely superseded by the propeller, screw propeller and other marine propulsion systems that have a higher efficiency, especially in rough or open water. Paddle wheels continue to be used by small, pedal-powered paddle boats and by some ships that operate tourist voyages. The latter are often powered by diesel engines. Paddle wheels The paddle wheel is a large steel framework wheel. The outer edge of the wheel is fitted with numerous, regularly spaced paddle blades (called floats or buckets). The bottom quarter or so of the wheel travels under wate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Capsizing
Capsizing or keeling over occurs when a boat or ship is rolled on its side or further by wave action, instability or wind force beyond the angle of positive static stability or it is upside down in the water. The act of recovering a vessel from a capsize is called righting. Capsize may result from broaching, , loss of stability due to cargo shifting or flooding, or in high speed boats, from turning too fast. If a capsized vessel has enough flotation to prevent sinking, it may recover on its own in changing conditions or through mechanical work if it is not stable while inverted. Vessels of this design are called self-righting. Small vessels In dinghy sailing, a practical distinction can be made between being knocked down (to 90 degrees; on its beam-ends, figuratively) which is called a capsize, and being inverted, which is called being turtled. Small dinghies frequently capsize in the normal course of use and can usually be recovered by the crew. Some types of dinghy ar ...

De Rebus Bellicis
("On the Things of Wars") is an anonymous work of the 4th or 5th century which suggests remedies for the military and financial problems in the Roman Empire, including a number of fanciful war machines. It was written after the death of Constantine I in 337 (it is explicitly stated that Constantine was dead when the work was written) and before the fall of the Western Roman Empire in 476. Some researchers suggest that it may refer to the Battle of Adrianople of 378 (it refers to the serious threat posed by the barbarian tribes to the empire), or even the death of Emperor Theodosius I in 395, as it uses the plural form of the word "princeps", the title of the emperor, which may refer to the split of the Empire between Honorius and Arcadius after the death of Theodosius.

Odometer
An odometer or odograph is an instrument used for measuring the distance traveled by a vehicle, such as a bicycle or car. The device may be electronic, mechanical, or a combination of the two (electromechanical). The noun derives from ancient Greek , ''hodómetron'', from , ''hodós'' ("path" or "gateway") and , ''métron'' ("measure"). Early forms of the odometer existed in the ancient Greco-Roman world as well as in ancient China. In countries using Imperial units or US customary units it is sometimes called a mileometer or milometer, the former name especially being prevalent in the United Kingdom and among members of the Commonwealth of Nations, Commonwealth. History Classical Era Possibly the first evidence for the use of an odometer can be found in the works of the ancient Roman Pliny the Elder, Pliny (NH 6. 61-62) and the ancient Greek Strabo (11.8.9). Both authors list the distances of routes traveled by Alexander the Great (r. 336-323 BC) as by his bematists Diog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vitruvius
Vitruvius ( ; ; –70 BC – after ) was a Roman architect and engineer during the 1st century BC, known for his multi-volume work titled . As the only treatise on architecture to survive from antiquity, it has been regarded since the Renaissance as the first book on architectural theory, as well as a major source on the canon of classical architecture. It is not clear to what extent his contemporaries regarded his book as original or important. He states that all buildings should have three attributes: , , and ("strength", "utility", and "beauty"), principles reflected in much Ancient Roman architecture. His discussion of perfect proportion in architecture and the human body led to the famous Renaissance drawing of the ''Vitruvian Man'' by Leonardo da Vinci. Little is known about Vitruvius' life, but by his own descriptionDe Arch. Book 1, preface. section 2. he served as an artilleryman, the third class of arms in the Roman military offices.

Life On The Mississippi
''Life on the Mississippi'' is a memoir by Mark Twain of his days as a steamboat pilot on the Mississippi River before the American Civil War published in 1883. It is also a travel book, recounting his trips on the Mississippi River, from St. Louis to New Orleans and then from New Orleans to Saint Paul, many years after the war. Overview The book begins with a brief history of the river as reported by Europeans and Americans, beginning with the Spanish explorer Hernando de Soto in 1542. It continues with anecdotes of Twain's training as a steamboat pilot, as the 'cub' (apprentice) of an experienced pilot, Horace E. Bixby. He describes, with great affection, the science of navigating the ever-changing Mississippi River in a section that was first published in 1876, entitled "Old Times on the Mississippi". Although Twain was actually 21 when he began his training, he uses artistic license to make himself seem somewhat younger, referring to himself as a "fledgling" and a "boy" ...
