nuclear weapon. J. Robert Oppenheimer, the director of the Los Alamos
Laboratory, took the name from a John Donne poem. It was conducted by
the United States Army on July 16, 1945, as part of the Manhattan
Project on the Alamogordo Bombing and Gunnery Range in the Jornada del
Muerto desert. The only structures originally in the vicinity were on
the McDonald Ranch site, which scientists used as a laboratory for
testing bomb components. A base camp was constructed, and there were 425
people present on the weekend of the test. It used a Fat Man bomb of the
same design as the one that would be detonated over Nagasaki. The
complex implosion-type nuclear weapon required a major design effort
from the Los Alamos Laboratory, and testing was required to allay fears
that it would not work. Its detonation (shown on video) produced the
explosive power of about 20 kilotons of TNT (84 terajoules). The test
site is now part of the White Sands Missile Range. It was declared a
National Historic Landmark district in 1965, and listed on the National
Register of Historic Places the following year.

Wikiquote quote of the day:
We knew the world would not be the same. A few people laughed,
a few people cried, most people were silent. I remembered the line from
the Hindu scripture, the Bhagavad-Gita... "Now, I am become Death, the
destroyer of worlds."
