The bright initial flash of a nuclear weapon is the first indication of a nuclear explosion, traveling faster than the blast wave or sound wave. [6] "A 1-megaton explosion can cause flash blindness at distances as great as 13 miles (21 km) on a clear day, or 53 miles (85 km) on a clear night.
Biophysicists have implicated acoustic impedance, or the ratio of acoustic pressure to particle velocity, as a factor contributing to blast damage in vivo. Wave transitions between tissues with significantly different acoustic impedances, particularly between the external environment and bone, causes focal mechanical damage as a result of wave ...
A blast injury is a complex type of physical trauma resulting from direct or indirect exposure to an explosion. [1] Blast injuries occur with the detonation of high-order explosives as well as the deflagration of low order explosives. These injuries are compounded when the explosion occurs in a confined space.
An explosion is a rapid expansion in volume of a given amount of matter associated with an extreme outward release of energy, usually with the generation of high temperatures and release of high-pressure gases. Explosions may also be generated by a slower expansion that would normally not be forceful, but is not allowed to expand, so that when ...
ALEX: I’d lock eyes with a picture of Bryan for five minutes before I could walk away. There’s one picture in the upstairs hallway. It’s his senior picture from high school. He’s looking directly into the camera. When you walk by it, it looks like he’s following you with his eyes. I would go to walk by him, and I couldn’t walk away.
Astronomers are anticipating the appearance of a “new star” triggered by an explosive event that could appear in the night sky anytime between now and September. ‘Once-in-a-lifetime ...
The "hey, Dwayne" got laughs in the room. ("Oh my God, I forgot about that whole thing," one person said at their table.) However, the bit didn't seem planned.
Commonly referred to as being "blown up", "blown apart", or "dashed to pieces" in older literature, [3] total body disruption may be caused by such traumas as being within or in close proximity to a powerful explosion, uncontrolled decompression, or implosion. It is the most severe type of blast injury. [4]
