Arbalest not be the same as an arbalest). In some cases, the word has been used to refer to arbalists, the people who actually used the weapon. Arbalest The arbalest (also arblast) was a late variation of the crossbow coming into use in Europe during the 12th century. A large weapon, the arbalest had a steel prod ("bow"). Since the arbalest was much larger than earlier crossbows, and because of the greater tensile strength of steel, it had a greater force. However, the greater draw weight was offset by the smaller powerstroke, which limited its potential in fully transferring the energy
Nuclear weapon design built. Most known innovations in nuclear weapon design originated in the United States, although some were later developed independently by other states. In early news accounts, pure fission weapons were called atomic bombs or A-bombs and weapons involving fusion were called hydrogen bombs or H-bombs. Practitioners however favor the terms nuclear and thermonuclear, respectively. Nuclear fission separates or splits heavier atoms to form lighter atoms. Nuclear fusion combines together lighter atoms to form heavier atoms. Both reactions generate roughly a million times more energy than comparable chemical reactions, making nuclear bombs a million times more powerful than non-nuclear bombs, which
