    en.wikipedia.org/wiki/14-inch/45-caliber_gun

    The 14-inch/45-caliber gun, (spoken "fourteen-inch-forty-five-caliber" [citation needed]), whose variations were known initially as the Mark 1, 2, 3, and 5, and, when upgraded in the 1930s, were redesignated as the Mark 8, 9, 10, and 12. They were the first 14-inch (356 mm) guns to be employed by the United States Navy.

  3. 3,4-Epoxycyclohexylmethyl-3',4'-epoxycyclohexane carboxylate

    en.wikipedia.org/wiki/3,4-Epoxycyclohexylmethyl-3...

    For homopolymerization of ECC 1.5 to 3 wt. % of an initiator are added. Above 3 wt% initiator no further acceleration was found, increasing proportions of initiators, however, increase the brittleness of the formed thermoset. After a photopolymerization usually still a thermal post-curing is necessary for a complete reaction. [5]

    en.wikipedia.org/wiki/.33_Winchester

    The .33 Winchester Center Fire / 8.6x54mmR (colloquially .33 Winchester, .33 WCF, [2] or .33 Win) is a centerfire rifle cartridge designed and produced from 1902 to 1940 by Winchester Repeating Arms Company for their Model 1886 lever-action rifle.

  5. Pythagorean triple - Wikipedia

    en.wikipedia.org/wiki/Pythagorean_triple

    Animation demonstrating the smallest Pythagorean triple, 3 2 + 4 2 = 5 2. A Pythagorean triple consists of three positive integers a, b, and c, such that a 2 + b 2 = c 2. Such a triple is commonly written (a, b, c), a well-known example is (3, 4, 5). If (a, b, c) is a Pythagorean triple, then so is (ka, kb, kc) for any positive integer k.

  6. Armour-piercing fin-stabilized discarding sabot - Wikipedia

    en.wikipedia.org/wiki/Armour-piercing_fin...

    Modern 120 mm tank gun shells. KE penetrators for modern tanks are commonly 23 cm (0.787–1.18 in) in diameter, and can approach 80 cm (31.5 in) long. As more structurally efficient penetrator-sabot designs are developed their length tends to increase, in order to defeat even greater line-of-sight armour depth.

  7. Bofors 40 Mk4 - Wikipedia

    en.wikipedia.org/wiki/Bofors_40_Mk4

    Bofors 40 mm 3P all-target programmable ammunition allows six modes including three proximity fuzing modes.This increases the flexibility and effectiveness of the gun system, which has further reduced the reaction time of the gun and it is possible to choose ammunition mode at the moment of firing, giving it the ability to switch rapidly between surface targets, air targets, and ground targets.

  9. Angstrom - Wikipedia

    en.wikipedia.org/wiki/Angstrom

    An example is Bragg's 1921 classical paper on the structure of ice, [11] which gives the c- and a-axis lattice constants as 4.52 A.U. and 7.34 A.U., respectively. Ambiguously, the abbreviation " a.u. " may also refer to the atomic unit of length, the bohr —about 0.53 Å—or the much larger astronomical unit (about 1.5 × 10 11 m ).
