Armourstone is a generic term for broken stone with stone masses between 100 and 10,000 kilograms (220 and 22,050 lb) (very coarse aggregate) that is suitable for use in hydraulic engineering. Dimensions and characteristics for armourstone are laid down in European Standard EN13383. [ 1 ]
Shot retrieved from the wreck of the Mary Rose (sunk in 1545, raised in 1982) are of different sizes, and some are stone while others are cast iron.

The principle of the kinetic energy penetrator is that it uses its kinetic energy, which is a function of its mass and velocity, to force its way through armor. If the armor is defeated, the heat and spalling (particle spray) generated by the penetrator going through the armor, and the pressure wave that develops, ideally destroys the target.
Early 15th-century Flemish giant cannon Dulle Griet at Ghent (caliber of 660 mm). This list contains all types of cannon through the ages listed in decreasing caliber size. For the purpose of this list, the development of large-calibre artillery can be divided into three periods, based on the kind of projectiles used, due to their dissimilar characteristics, and being practically ...

Dice are used for generating random values, commonly as part of tabletop games, including dice games, board games, role-playing games, and games of chance.
Long dice [1] (sometimes oblong [2] or stick [2] [3] dice) are dice, often roughly right prisms or (in the case of barrel dice) antiprisms, designed to land on any of several marked lateral faces, but neither end. Landing on end may be rendered very rare simply by their small size relative to the faces, by the instability implicit in the height ...
