A submarine is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. The term most commonly refers to a large, crewed, autonomous vessel. It is also sometimes used historically or colloquially to refer to remotely operated vehicles and robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub. Used as an adjective in phrases such as submarine cable, "submarine" means "under the sea". The noun submarine evolved as a shortened form of submarine boat (and is often further shortened to sub). For reasons of naval tradition, submarines are usually referred to as "boats" rather than as "ships", regardless of their size.
Although experimental submarines had been built before, submarine design took off during the 19th century, and they were adopted by several navies. Submarines were first widely used during World War I (1914–1918), and now figure in many navies large and small. Military usage includes attacking enemy surface ships (merchant and military), submarines, aircraft carrier protection, blockade running, ballistic missile submarines as part of a nuclear strike force, reconnaissance, conventional land attack (for example using a cruise missile), and covert insertion of special forces. Civilian uses for submarines include marine science, salvage, exploration and facility inspection/maintenance. Submarines can also be modified to perform more specialized functions such as search-and-rescue missions or undersea cable repair. Submarines are also used in tourism, and for undersea archaeology.
In baseball, a submarine pitch is one in which the ball is released underhand, and often just above the ground, with the torso bent at a right angle and shoulders tilted so severely that they rotate around a nearly horizontal axis. (This is in stark contrast to an underhand pitch in softball in which the torso remains upright, the shoulders are level, and the hips do not rotate.)
The "upside down" release of the submariner causes balls to move differently from pitches generated by other arm slots. Gravity plays a significant role, for the submariner’s ball must be thrown considerably above the strike zone, after which it drops rapidly back through. The sinking motion of the submariner’s fastball is enhanced by forward rotation, in contradistinction to the overhand pitcher’s hopping backspin.
Submarine pitches are often the toughest for same-side batters to hit (i.e., a right-handed submarine pitcher is the more difficult for a right-handed batter to hit, and likewise for left-handed pitchers and batters). This is because the submariner’s spin is not perfectly level; the ball rotates forward and toward the pitching arm side, jamming same-sided hitters at the last moment, even as the ball drops rapidly through the zone.
Marine geology or geological oceanography is the study of the history and structure of the ocean floor. It involves geophysical, geochemical, sedimentological and paleontological investigations of the ocean floor and coastal zone. Marine geology has strong ties to physical oceanography.
Marine geological studies were of extreme importance in providing the critical evidence for sea floor spreading and plate tectonics in the years following World War II. The deep ocean floor is the last essentially unexplored frontier and detailed mapping in support of both military (submarine) objectives and economic (petroleum and metal mining) objectives drives the research.
The Ring of Fire around the Pacific Ocean with its attendant intense volcanism and seismic activity poses a major threat for disastrous earthquakes, tsunamis and volcanic eruptions. Any early warning systems for these disastrous events will require a more detailed understanding of marine geology of coastal and island arc environments.
Human resources is the set of individuals who make up the workforce of an organization, business sector, or economy. "Human capital" is sometimes used synonymously with human resources, although human capital typically refers to a more narrow view (i.e., the knowledge the individuals embody and economic growth). Likewise, other terms sometimes used include "manpower", "talent", "labour", or simply "people".
Staffing is a process of hiring, positioning and overseeing employees in an organisation.
Pioneering economist John R. Commons used the term "human resource" in his 1893 book The Distribution of Wealth but did not further build upon it. The term "human resource" was subsequently in use during the 1910s and 1920s as was the notion that workers could be seen as a kind of capital asset. Among scholars the first use of "human resources" in its modern form was in a 1958 report by economist E. Wight Bakke. The term began to become more developed in the 19th century due to misunderstandings between the employers and employees.

Deep beneath the surface of the world's oceans, Sweden's submarines possess incredible capabilities that have long been shrouded in mystery. These silent predators of the deep have garnered a reputation for audacious feats and technological prowess that leaves the maritime world astounded. From "sinking" a U.S. Navy aircraft carrier to skillfully eluding sophisticated antisubmarine defenses, Sweden's submarines have proven their mettle time and again. With Sweden's recent entry into NATO, these submarines are poised to become a true game-changer for the alliance's defense strategy. Their unmatched capabilities raise an important question: How do these silent predators of depth enhance and strengthen NATO's overall capabilities?

The SSBN Typhoon-class submarine, officially designated the Akula (“Shark”) in Russia, is a Cold War behemoth measuring 175 meters long and displacing 48,000 tonnes as it sinks. That's double the tonnage of American Ohio-class SSBNs it was meant to compete with. No less than five internal pressure hulls made of ultra-expensive titanium gave the Typhoon outstanding resistance to battle damage. The Typhoon was the largest submarine ever built. #TyphoonClassSubmarine #Submarine #RussianNavy #RussianSubmarine Copyright Disclaimer under Section 107 of the Copyright Act of 1976, allowance is made for "fair use" for purpose such as criticism, comment, news reporting, teaching, scholarship, and research.

For the money though, the country will get enormous firepower in the form of the most advanced, and lethal, fighting machine humans can build. The politicians who engineered the deal through the AUKUS security pact say we will also obtain something that’s impossible to put a price on: stability in our region. China definitely doesn’t agree, but the theory is that by showing our fighting capability, Australia is really proving how much we want peace. But what are these submarines really like?
