Shut up Greg
Military contractor DSG Technologies created a bullet that has its tip coated in tungsten,
allowing it to create a small air bubble in front of it — a process called “supercavitation.
A .50 caliber CavX round can travel 60 meters underwater, according to Defense One.
They disintegrate when they hit water, not when they're fired from within it. Same principle as the Gyrojet guns (and as I recall Gyrojet adapted their design for underwater combat at some point).Adorno said:But small projectiles? Obviously a submarine can fire torpedoes, but bullets just disintegrate when hitting water.
Danath's example above is relevant, and that's only with normal ammunition. If you were to look up Gyrojet they specialized in self-propelled ammunition technology for space combat - essentially miniaturized rocket bullets. There were plans to adapt this for underwater combat before they went bankrupt.Adorno said:Are you saying you can fire a regular firearm underwater? Water is pretty solid compared to air. The bullet wouldn't go more than 1-2 metres, I imagine.
Cool. Those communists knew how to keep their waters safe.Danath said:https://en.wikipedia.org/wiki/ADS_amphibious_rifle The weapon's effective underwater firing range when using the specially designed cartridge is about 25 meters at a depth of 5 meters and 18 m at a depth of 20 m
https://en.wikipedia.org/wiki/APS_underwater_rifle Effective firing range 30 m at depth 5 m (98 ft at depth 16 ft)
Introduction said:A growing body of research suggests that populations around the globe vary substantially along several important psychological dimensions and that populationscharacterized as Western, Educated, Industrialized, Rich, and Democratic (WEIRD) are particularly unusual. People from these societies tend to be more individualistic, independent, and impersonally prosocial (e.g., trusting of strangers) while revealing less conformity and in-group loyalty. Although these patterns are now well documented, few efforts have sought to explain them. Here, we propose that the Western Church (i.e., the branch of Christianity that evolved into the Roman Catholic Church) transformed European kinship structures during the Middle Ages and that this transformation was a key factor behind a shift towards a WEIRDer psychology.
Results said:We test these predictions at three levels. Globally, we show that countries with longer historical exposure to the medieval Western Church or less intensive kinship (e.g., lower rates of cousin marriage) are more individualistic and independent, less conforming and obedient, and more inclined toward trust and cooperation with strangers (see figure). Focusing on Europe, where we compare regions within countries, we show that longer exposure to the Western Church is associated with less intensive kinship, greater individualism, less conformity, and more fairness and trust toward strangers. Finally, comparing only the adult children of immigrants in European countries, we show that those whose parents come from countries or ethnic groups that historically experienced more centuries under the Western Church or had less intensive kinship tend to be more individualistic, less conforming, and more inclined toward fairness and trust with strangers.
Conclusion said:This research suggests that contemporary psychological patterns, ranging from individualism and trust to conformity and analytical thinking, have been influenced by deep cultural evolutionary processes, including the Church’s peculiar incest taboos, family policies, and enduring kin-based institutions.
