Then, the day after the nuclear explosion, the contaminated dust and water rain down and contaminate a large area. This rain is known as the fallout. The head wave comes from the gigantic energy that develops from the detonation. In the center of the detonation, the temperature can reach several million degrees. The head wave only takes a few seconds, but it kills everyone within a three-mile radius.
LOGISTICAL ALTERNATIVES Driscoll O. Scanlan was the mine inspector at the mine when this disaster occurred. John Bartlow Martin’s account of the blast indicates that Scanlan performed all required inspections and wrote detailed reports to the proper officials concerning the problems at Centralia No. 5 that ultimately led to the blast. The main issue at hand was the violation of the federal mine code for rock dusting in a dangerous dusty mine. Adequate rock dusting should have been performed to localize any explosion.
The identity of the attackers still had not been determined tonight. Truck Loaded With TNT According to a Pentagon spokesman, a Mercedes truck filled with some 2,500 pounds of TNT broke through a series of steel fences and sandbag barricades and detonated in the heart of the Marines' administrative headquarters building shortly after dawn. The explosion collapsed all four floors of the building, turning it into a burning mound of broken cement pillars and cinder blocks. Although a marine sentry was able to fire about five shots at the suicide driver and another marine threw himself in front of the speeding, explosive- filled truck, neither could block its entry into the headquarters building, where it exploded in a fireball that left a crater 30 feet deep and 40 feet wide. In a haunting scene late tonight, rescue workers using blow torches, pneumatic drills and cranes worked furiously under floodlights to pry out the dead and wounded still crushed beneath the smouldering debris.
Many of the deadliest battles in history occurred during the First World War. Such battles include Ypres, the Marne, Cambrai, the Somme, Verdun, and Gallipoli. The Germans employed the Haber process of nitrogen fixation to provide their forces with a constant supply of gunpowder, despite the British naval blockade. [143] Artillery was responsible for the largest number of casualties[144] and consumed vast quantities of explosives. The large number of head wounds caused by exploding shells and fragmentation forced the combatant nations to develop the modern steel helmet, led by the French, who introduced the Adrian helmet in 1915.
Three, two, one, fire! This is the command you would have heard right before the hit of rocks, stones, or even dead animal meat which left holes in crumbling castle walls in medieval times. The source of the projectile, and one of the most feared weapons of medieval times was a trebuchet, a powerful machine used to hurl projectiles. Trebuchets were able to throw massive objects at high speeds over great distances with great accuracy. Hurling objects into the air with great force has sparked great interest about the construction and operation of trebuchets.
Hydraulic Fracturing was invented by Halliburton in the 1940’s. The method injects a mixture of sand, water, and chemicals (a large amount of them toxic) into deep underground rock formations to rupture them and release natural
Response Paper 6: Everything Was Different Summary The scientists working on the Manhattan Project carted the parts for the first nuclear bomb test to Los Alamos. Once there the scientists assembled the bomb which consisted of an outer ring of plutonium surrounding an inner shell of beryllium containing polonium. This bomb was then hoisted to the top of a 100 foot tower to await its detonation at 5:30 am the next morning. The scientists viewed the explosion and dust cloud from a shelter approximately 6 miles from the drop site. After the excitement that experiment was successful died down the scientists discovered that the explosion and fallout from the bomb were more severe than expected.
Devastation, destruction, terror, and straight up fear, is what people would’ve seen if they visited Nagasaki or Hiroshima after the atomic bomb was dropped on those cities. The number of scientists who were involved in the development of the atomic bomb is unbelievable. The bombs were very unique objects, whether it was the size of the bomb, or even the amount of explosives inside. The names of the atomic bombs will forever be remembered for the chaos they brought to Japan. The decision to drop the bombs was one of the most difficult things President Truman had to do during his Presidency.
On September 13th, 1848 a man named Phineas Gage was working as a foreman blasting rock to lay bed for a rail line. Gage had to pack gunpowder into a hole in order to blast the rock. On a particular occasion as he was doing just this it exploded sending an iron rod, 1 ¼ inch in diameter and over 3 feet in length through his head. The rod entered the side of his face, passed behind the left eye, and finally exiting at the top of his head. Gage amazingly was lucid and speaking after only a few minutes.
Rock dusting is the applying of pulverized stone to the walls and roofs of the passage ways, which would have killed the explosions by throwing a cloud of rock dust that is incombustible into the air with coal dust. Why weren’t any methods like that implemented if it was known for more than twenty-five years prior to the incident and it was known about the mine being
