Over 2,000 detonations! Really informative. Duncan Geere writes on Wired.com (UK):
A Japanese artist named Isao Hashimoto has created a series of works about nuclear weapons. One is titled “1945—1998” and shows a history of the world’s nuclear explosions.
Over the course of fourteen and a half minutes, every single one of the 2,053 nuclear tests and explosions that took place between 1945 and 1998 are is plotted on a map.
After a couple of minutes or so, however, once the USSR and Britain entered the nuclear club, the tests really start to build up, reaching a peak of nearly 140 in 1962, and remaining well over 40 each year until the mid-80s.
It’s a compelling insight into the history of humanity’s greatest destructive force, especially when you remember that only two nuclear explosions have ever been detonated offensively, both in 1945. Since then, despite more than 2,000 other tests and billions of dollars having been spent on their development, no nuclear warheads have been used in anger.
