Stepan Osipovich Makarov
Stepan Osipovich Makarov (, ; – ) was a Russian vice-admiral, commander in the Imperial Russian Navy, oceanographer, member of the Russian Academy of Sciences, and author of several books. He was a pioneer of insubmersibility theory (the concept of counter-flooding to stabilise a damaged ship), and developer of a Cyrillic-based semaphore alphabet. A proponent of icebreaker use, he supervised the first polar icebreaker construction. Makarov also designed several ships. Makarov saw service in the Russo-Turkish War (1877–1878) as a captain, and ordered the first successful attack with a self propelled torpedo. He served again in the Russo-Japanese War as vice-admiral and was assigned to the defense of Port Arthur, where he was hailed as a competent and aggressive commander. On 13 April 1904 Makarov led his flotilla to the aid of a destroyer that had been ambushed by the Japanese. Makarov was killed in the subsequent battle when his flagship ''Petropavlovsk'' struck a n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oceanographer
Oceanography (), also known as oceanology, sea science, ocean science, and marine science, is the scientific study of the ocean, including its physics, chemistry, biology, and geology. It is an Earth science, which covers a wide range of topics, including ocean currents, waves, and geophysical fluid dynamics; fluxes of various chemical substances and physical properties within the ocean and across its boundaries; ecosystem dynamics; and plate tectonics and seabed geology. Oceanographers draw upon a wide range of disciplines to deepen their understanding of the world’s oceans, incorporating insights from astronomy, biology, chemistry, geography, geology, hydrology, meteorology and physics. History Early history Humans first acquired knowledge of the waves and currents of the seas and oceans in pre-historic times. Observations on tides were recorded by Aristotle and Strabo in 384–322 BC. Early exploration of the oceans was primarily for cartography and mainly limited ...

Magazine (artillery)
A magazine is an item or place within which ammunition or other explosive material is stored. The word is taken originally from the Arabic word ''makhāzin'' (مخازن), meaning "storehouses", via Italian and Middle French. The term is also used for an ammunition dump, a place where large quantities of ammunition are stored for later distribution. This usage is less common. Field magazines In the early history of tube artillery drawn by horses (and later by mechanized vehicles), ammunition was carried in separate unarmored wagons or vehicles. These soft-skinned vehicles were extremely vulnerable to enemy fire and to explosions caused by a weapons malfunction. Therefore, as part of setting up an artillery battery, a designated place would be used to shelter the ready ammunition. In the case of batteries of towed artillery the temporary magazine would be placed, if possible, in a pit, or natural declivity, or surrounded by sandbags or earthworks. Circumstances might requ ...

Russian Battleship Petropavlovsk (1894)
''Petropavlovsk'' () was the lead ship of her class of three pre-dreadnought battleships built for the Imperial Russian Navy during the last decade of the 19th century. The ship was sent to the Far East almost immediately after entering service in 1899, where she participated in the suppression of the Boxer Rebellion the next year and was the flagship of the First Pacific Squadron. At the beginning of the Russo-Japanese War of 1904–1905, ''Petropavlovsk'' took part in the Battle of Port Arthur, where she was lightly damaged by Japanese shells and failed to score any hits in return. On 13 April 1904, the ship sank after striking one or more mines near Port Arthur, in northeast China. Casualties numbered 27 officers and 652 enlisted men, including Vice Admiral Stepan Makarov, the commander of the squadron, and the war artist Vasily Vereshchagin. The arrival of the competent and aggressive Makarov after the Battle of Port Arthur had boosted Russian morale, which plummeted aft ...

Port Arthur, China
The asterisk ( ), from Late Latin , from Ancient Greek , , "little star", is a typographical symbol. It is so called because it resembles a conventional image of a heraldic star. Computer scientists and mathematicians often vocalize it as star (as, for example, in ''the A* search algorithm'' or ''C*-algebra''). An asterisk is usually five- or six-pointed in print and six- or eight-pointed when handwritten, though more complex forms exist. Its most common use is to call out a footnote. It is also often used to censor offensive words. In computer science, the asterisk is commonly used as a wildcard character, or to denote pointers, repetition, or multiplication. History The asterisk was already in use as a symbol in ice age cave paintings. There is also a two-thousand-year-old character used by Aristarchus of Samothrace called the , , which he used when proofreading Homeric poetry to mark lines that were duplicated. Origen is known to have also used the asteriskos t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yermak (1898 Icebreaker)
''Yermak'' ( rus, Ермак, p=Jɛrmak) was a Russian and later Soviet icebreaker. It was the first polar icebreaker in the world, having a strengthened hull shaped to ride over and crush pack ice. History An earlier vessel, the schooner Yermak, was commissioned for the 1862 attempt to find the Yenissei river delta by Paul Theodor von Krusenstern, by navigating from Murmansk through the Kara Sea to the destination, but unfortunately was shipwrecked before obtaining success.Naufrage du lieutenant Krusenstern dans les glaces de la mer de Kara (1863, in Le Tour du monde Volume 8 pp.203-208) ''Yermak'' was built for the Imperial Russian Navy under the supervision of vice-admiral S. O. Makarov by the members of his commission, which included D. I. Mendeleev, engineers N. I. Yankovsky and R. I. Runeberg, admiral F. F. Wrangel, among others. It was built in Newcastle upon Tyne at its Low Walker yard and launched in 1898. She was named after the famous Russian explorer of Sibe ...

Icebreaker
An icebreaker is a special-purpose ship or boat designed to move and navigate through ice-covered waters, and provide safe waterways for other boats and ships. Although the term usually refers to ice-breaking ships, it may also refer to smaller vessels, such as the icebreaking boats that were once used on the canals of the United Kingdom. For a ship to be considered an icebreaker, it requires three traits most normal ships lack: a strengthened hull, an ice-clearing shape, and the power to push through sea ice. Icebreakers clear paths by pushing straight into frozen-over water or pack ice. The bending strength of sea ice is low enough that the ice breaks usually without noticeable change in the vessel's trim. In cases of very thick ice, an icebreaker can drive its bow onto the ice to break it under the weight of the ship. A buildup of broken ice in front of a ship can slow it down much more than the breaking of the ice itself, so icebreakers have a specially designed hull ...

Semaphore Alphabet
Flag semaphore (from the Ancient Greek () 'sign' and - (-) '-bearer') is a semaphore system conveying information at a distance by means of visual signals with hand-held flags, rods, disks, paddles, or occasionally bare or gloved hands. Information is encoded by the position of the flags; it is read when the flag is in a fixed position. Semaphores were adopted and widely used (with hand-held flags replacing the mechanical arms of semaphore line, shutter semaphores) in the maritime world in the 19th century. It is still used during underway replenishment at sea and is acceptable for emergency communication in daylight or using lighted wands instead of flags, at night. Contemporary semaphore flag system The current flag semaphore system uses two short poles with square flags, which a signal person holds in different positions to signal letters of the alphabet and numbers. The signaller holds one pole in each hand, and extends each arm in one of eight possible directions. Except ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
