In physics, a shock wave (also spelled shockwave), or shock, is a type of propagating disturbance that moves faster than the local speed of sound in the medium. Like an ordinary wave, a shock wave carries energy and can propagate through a medium but is characterized by an abrupt, nearly discontinuous, change in pressure ...
In fluid dynamics, a blast wave is the increased pressure and flow resulting from the deposition of a large amount of energy in a small, very localised volume. The flow field can be approximated as a lead shock wave, followed by a self-similar subsonic flow field. In simpler terms, a blast wave is an area of pressure expanding ...
In general, surrounding a bomb with denser media, such as water, absorbs more energy and creates more powerful shockwaves while at the same time limiting the area of its effect. When a nuclear weapon is surrounded only by air, lethal blast and thermal effects proportionally scale much more rapidly than lethal radiation effects as ...
4. Aug. 2005 · Sixty years ago Saturday, the B-29 bomber Enola Gay loosed a 10,000-pound atomic bomb over the Japanese city of Hiroshima. We remember Aug. 6, 1945, and the people whose lives were changed by it.
6. Aug. 2020 · The web page reports on the anniversary of the first atomic bomb dropped on Hiroshima by the US in 1945, and the impact of the bombing on the city and the world. It also provides historical context, personal stories and perspectives on the controversial issue of nuclear weapons.
