Castle Bravo
Castle Bravo was the first in a series of high-yield thermonuclear weapon design tests conducted by the United States at Bikini Atoll, Marshall Islands, as part of "Operation Castle". Detonated on March 1, 1954, the device was the most powerful nuclear device detonated by the United States and its first lithium deuteride fueled thermonuclear weapon. Castle Bravo's yield was 15 megatons of TNT, 2.5 times the predicted 6.0 megatons, due to unforeseen additional reactions involving Li, which led to the unexpected radioactive contamination of areas to the east of Bikini Atoll.
Giovanni Battista Trevano
Trevano started working in Poland around 1600. He was one of the team of architects and craftsmen who rebuilt the Royal Castle in Warsaw, on the basis of the old Gothic castle of the Masovian princes, which had already been completely remodeled by Italian architects in the second half of the sixteenth century. New work was undertaken in the years 1598-1619. He was not alone in this project: Giacomo Rodondo, Paolo del Corte and Mateo Castelli were all involved in remaking the castle into a new Baroque structure, on its imposing site along the bank of the river Vistula. The castle, much altered over the years, was bombed and dynamited by the Nazis as a symbol of Polish culture and was rebuilt in the years 1971–1988 as a national monument.
