Armageddon & Physics Essay Example for Free

Armageddon Physics Essay In 2007, the September 1st issue of The New Scientist alleges that the film Armageddon is shown by the management training programs of the National Aeronautics and Space Administration (NASA). A 1998 Jerry Bruckheimer-produced disaster thriller directed by Michael Bay in which deep core drillers attempt to avert an asteroid’s collision with the planet Earth, The New Scientist contends that NASA’s screening of a razzle-dazzle blockbuster claiming ground in science, is purely for entertainment purposes. â€Å"†¦the screenings are just a game for NASAs space geeks: who can find the highest number of impossible things in the movie? The record, [†¦] stands at 168. † Regarding the scientific fallaciousness of Armageddon, astronomer Philip Plait has many contentions. Plait notes that the introductory premise of the film, in which an asteroid of the same size which humanity faces was a â€Å"dinosaur killer† that possesses the same destructive capacity of â€Å"10,000 nuclear weapons. † However, he asserts that this is a severe underestimation, for the fictional asteroid would actually release at the very least, eight hundred thousand nuclear weapons, based on conservative estimates. Plait implicitly infers that the writers were going for a dramatic figure, but one whose complete lack of scientific basis leads to a severe underestimate. It is also preposterous for it to be impossible to communicate the drilling experience of an oil rig crew to astronauts or engineers, former engineer turned writer Tom Rogers notes. However, this is how the movie rationalizes the oil rig crew’s participation in Earth’s salvation despite their complete lack of astronautical experience. But even excusing such a premise, Rogers notes that the film stretches credulity when the Mir space station rotates at high velocities to induce artificial gravity. Amazingly enough, it rotates so fast that it can create gravitonic conditions in under half a minute, despite the fact that the Mir station’s mass exceeds a hundred tons. Rogers’ contention in this scenario is that the planetary gravity conditions could not be possibly simulated unless the human’s height is a small percentage of the rotational radius. As such, the astronauts would only experience gravitonic force on both ends of their bodies, which would feel â€Å"disorienting and probably cause [them] to stumble and vomit. † The Jupiter Scientific Organization also asserts that NASA’s plan of inserting a hydrogen bomb eight hundred feet deep into an asteroid that is three hundred miles wide – essentially a Texas-sized asteroid, which is exactly what it is called at one point in the film – does not actually scale very well. The film’s core (all pun intended) premise is actually absurd: attempting to split an asteroid with two pieces by exploding it with a hydrogen from within would be like hypothesizing that a single hydrogen bomb could fracture the state of Texas. It’s â€Å"like a pin-sized hole no deeper than a scratch in a ten-foot rock. † Such a hydrogen bomb â€Å"would roughly be like lighting a match. Can the ignition of such a match split a ten-foot rock? † Rogers also observes that a flaming shuttle crash site contradicts what the astronauts are told earlier about the gravity being about a tenth of that on the planet Earth. Such a low gravity cannot support an atmosphere – which is why they wear space suits in the first place: the asteroid surface does not and could not hold oxygen – yet for some reason, flames burn in the absence of oxygen. Lastly, a successfully halved asteroid would still be disaster, as the gravitonic forces they exert would cause catastrophic tidal changes that would eradicate most of the Earth’s population. â€Å"Sometimes theres just no way to have a happy ending,† Rogers notes.

Eating Disorders Essay -- essays research papers

Millions of American women struggle with eating disorders. An eating disorder is a disturbance in eating behavior. Most people associate eating disorders with anorexia nervosa, "active self-starvation or sustained loss of appetite that has psychological origins" (Coon 133), or bulimia nervosa, "excessive eating (gorging) usually followed by self-induced vomiting and/ or taking laxatives (Coon 411). They need to purge their bodies of calories in any way possible, so they may also use diuretics or even exercise compulsively. Their body images are severely distorted. They're the most talked about and the best studied eating disorders, and researchers estimate that nearly seven million women in the United States suffer from either anorexia or bulimia. But there's a newly recognized condition known as binge-eating disorder that is now considered the most common eating disorder. In the U.S. population, it has a frequency of about one to four out of every one hundred people. Although eating disorders afflict women much more often than they do men, it is estimated that about one million American men suffer from either anorexia or bulimia, and millions more have binge-eating disorder. Eating disorders are much more prevalent in industrialized countries. According to the American Psychiatric Association, eating disorders are most common in the United States, Canada, Europe, Australia, Japan, New Zealand, and South Africa. Americans today live in a fat-phobic society where, from a very early age, girls are raised to think that thin is better. The famous writer and theater critic Dorothy Parker once said, "no woman can be too rich or too thin," words that quickly became a catchphrase still used today. Many of us grow up learning to associate fat with ugliness and failure. Advertisements bombard us with thinner-than-normal models. Most Miss America contestants and fashion supermodels are more than fifteen percent below the expected weight for their height and age, a criterion for anorexia according to the American Psychiatric Association (Breen). It is not surprising to hear reports of healthy, children of normal weight who are concerned about their diet and afraid of becoming too fat, and of an increasing number of girls who haven't yet reached puberty who are showing signs of... ...ill take care of it for them. Their mindset needs to be changed, so by taking these burdens off of their shoulders, they will have less to worry about and more time to concentrate on getting well. This whole process is very difficult and very time consuming but well worth it in the end. These victims are probably the most caring and selfless of anyone, and they need to realize this point. So in helping them do so, you need to show them how many people are there for them and how many people care them and want them to get better. Basically, the good feelings are going to try to overpower the negative mind, making it mute. In conclusion, eating disorders are treatable through proper care and therapy. It is not something to take lightly and needs to be treated as soon as possible. Though these disorders can be treated they will never be completely cured; they are more â€Å"under control† than anything. So just because a person may start to eat more does not mean that everything is over and should be forgotten. Right from the very beginning when it is first noticed that there is a problem, professional help should be sought out.

Maritime Law Essay

On January 6th, 2007 the vessel collided with â€Å"M. V Container† while approaching to pilot station. The cause of the collision was due to wrong plotting position of 3rd officer from â€Å"Never Struck† and wrongful act on COLREG 72 from â€Å"M. V Container†. Owners of the â€Å"M. V Container† claimed her damage cargo hold No 1. Cargo owner of fertilizer claimed to owner against delays. 4. general average vs. particular average (a) General average is incurred for the benefit of all interests but the particular average is in connection with just one of the many interests. b) General average is always voluntary and intentional but the particular average is an accidental or unexpected calamities. (c) General average is shared by all those who have benefited by the general average act. Particular average is paid by the insurer. (d) General average may include expenditure and sacrifice along with loss, whereas the particular average results from a loss or damage. 5. Conditions implying General Average In order for an act of sacrifice or expenditure to be considered an act of general average, six conditions must prevail. a) Common Maritime Adventure – More than one party must be involved in the adventure so as to be ‘common’ (shipowner, cargo owner). (b) Real and Common Danger – all parties must have been actually benefited by the sacrifice due to a peril that endangers the adventure. (c) Extraordinary – loss must be distinguished from ordinary loss because ordinary loss is not allowed for general average contributions. (d) Intentional – decisions must be made and the loss must be voluntary. (e) Reasonableness – unreasonable and unnecessary sacrifice or expenditure is not valid. f) Success – the sacrificial actions must be able to save the property involved in a common maritime adventure from a particular danger. Where the ship and cargo is totally destroyed altogether, there will be no quest ion of general average. 6. CASE ANALYSIS In the case of â€Å"Never Struck† and â€Å"M. V Container†, it was due to the negligence of 3rd officer in â€Å"M. V Container† who did not condone to Prevention of Collision Regulations 1972 which is a breach of international law, causing the two vessels to collide. Although â€Å"Never Struck† did have a fault of its own, it did not however breach the international law of sea navigations. In applying the rules of Prevention of Collision Regulations 1972, Part A, section 2(a) and section 2(b), referred to as the â€Å"General Prudential† rule and provides for non-conformance with stated rules in order to prevent a collision, because what is paramount is to avoid or minimize the damaging effects of a collision, as opposed to blindly following the rules to the letter. The overall intent is to minimize actual collision taking place rather than rule compliance in itself. Due to negligence on the part of â€Å"M. V Container† she will not be able to claim against â€Å"Never Struck† for the repairs of the cargo hold No 1. The cargo loss in the cargo hold No 1 which was lost due to the accident may however bring about an action in tort. If there was any further loss of cargo which was jettisoned in order to save the ship or expenses incurred after the collision in order to save the adventure may be liable for general average. As for â€Å"Never Struck†, the cargo owner may claim either â€Å"Never Struck† or â€Å"M. V Container† against delays. However it should and would not be considered in general average claims. Same as for the case of â€Å"M. V Container†, the cargo loss which was lost due to the accident may however bring about an action in tort. If there was any further loss of cargo which was jettisoned in order to save the ship or expenses incurred after the collision in order to save the adventure may be liable for general average. 7. CONCLUSION As a conclusion, collisions may lead to a series of claims and actions. These series of events may bring about the application a number of acts. It is important though to understand that General Average only exist if the act of sacrifice or expenditure is voluntary in order to save a common adventure from total loss at sea.
