I Choose Thus Project Because When Watching Television Both Name Brand
I choose thus project because when watching television both name brand batteries claim to be the best. I wanted to see which one actually did last the longest. The Encyclopedia's I did my research in say a battery is a device which transforms chemical energy. The term is usually applied to a group of two or more electric cells connected together electrically. In comman usage the term battery is also applied to a single cell, such as a flashlight battery. There are in general two types of batter...

Weapons Of The Civil War
Weapons of the Civil War The Civil War has been the worst tragedy that this country has experienced throughout our nation's fairly young existence. It will forever be a permanent scar that will blemish the history of the United States of America. The Civil War amassed more American casualties than all other wars combined. This fact is partially due to the amazing advancement of firearms during the era of the Civil War. Both the C.S.A. and USA were fractionally responsible for creating this sudd...

Combinatorial Chemistry
Combinatorial Chemistry And New Drugs The body fights disease by generating antibodies that bind to invading organisms. The body can make different antibodies by shuffling and reshuffling their constituent parts, but it can't make a special antibody each time it is faced with a new pathogen. So it uses only the antibodies that will work best and makes more of them. In the past few years, chemists have begun to follow this method to develop new drugs. Instead of looking for signs of a desired ac...

Ironclad Ships
Ironclad Ships The Battle of Hampton Roads changed the course of naval history. This battle marked the first time that two ironclad warships engaged in ship to ship combat. However the USS Monitor and Popov and the Novgorod. These circular monitors were impossible to control and just drifted around (Greene 351-356). The civil wars in South America also saw widespread use of ironclad warships, especially in Chile and Brazil. The revolutionaries of Peru purchased unfinished Confederate ironclads f...

Flying Tired
Flying Tired CHAPTER I Introduction Pilots today are working in a 24-hour a day industry. The potential for error when working during the night is higher than working during the day. Humans have an internal clock that prefers you sleep at night; so working at night is a valid safety issue. Pilots today should be considered as shift workers, their schedules can be from early morning one day until the early morning of the next day and any combination in between. The fact that they deal with weathe...

The Discovery Of Fluorine
The discovery of Fluorine title = The discovery of Fluorine The isolation of fluorine had challenged chemist for many years, taking the lives of at least two scientists in the process. Fluorine receives its name from the Latin, fluo, meaning flow. The first real attempt to free fluorine, was done by a chemist by the name of Humphyry Davy, between the years of (1811-1813). He first tried to liberate the element by using the chemical methods, but this failed. He then went on to try and electrolysi...

Was The Civil War Worth It?
Was The Civil War Worth It? Was the civil war worth it? I believe that the civil war was worth it. Even though a lot of negative consequences came out of it, the positive changes outweighed the negative. To get a full understanding of why it was positive, one will have to understand what were the causes of war, changes resulting from war, and the consequences. The largest cause was the differences in thoughts about slavery. The North and South had contained their differences over slavery for six...

Cardiac Pacemakers
Cardiac Pacemakers CARDIAC PACEMAKERS The heart is bestowed with a specialized system that automatically generates rhythmic control via the sinus node, located in the superior lateral wall of the right atrium near the opening of the superior vena cava. The specialized pacemaker cells dictate control of the rest of the heart through regular electrical impulses that propagate from the right atria to the lower ventricles. The rapid conduction of these impulses cause the muscle cells of the atria to...

Impact Of Robtic Program
Impact Of Robtic Program I saw the flier from Tech, and it was second week of school. I spotted out a robotic course at MIT. The program seemed tailored to my interest in math and science and to my competitive spirit. I couldn't resist the opportunity. When I asked some of my friends if they were willing to sign up for a course with me, most of them discouraged me by telling me it was too advanced for them or they did not have time for such a course. Finally one of my friends and I signed up. Th...

Manganese
Manganese Hi, I am Manganese. I am an element discovered in 1774 by the Swedish chemist Johan Gottlieb Gahn. My symbol was devised, coincidentally, by taking the first and third letters in the word manganese. My atomic number is 25, my atomic mass is 54.938, and my density is 7.2. I melt at 1245? C and then in turn I boil at 1962? C. A fact about my ionization energy currently escapes me, but I do have some uses and interesting facts in the rest of the paper. I am used as an antioxidant nutrient...

Tigers
Tigers Tigers are descended from civet-like animals called niacis that lived during the age of the dinosaurs about 60 million years ago (Dang, 1994). These small mammals, with long bodies and short flexible limbs, evolved over millions of years into several hundred different species, including cats, bears, dogs and weasels. About 37 cat species exist today (Dang, 1994). Tigers evolved in eastern Asia , but it is not exact. Sabre-tooth tigers are not the ancestors of today's tigers. In fact, sabr...

The Case For The Existence Of God
The Case For The Existence of God by Bert Thompson, Ph.D. Introduction Either God exists or He doesn't. There is no middle ground. Any attempt to remain neutral in relation to God's existence is automatically synonymous with unbelief. It is far from a moot question, for if God does exist, then nothing else really matters; if He does not exist, then nothing really matters at all. If He does exist, then there is an eternal heaven to be gained (Hebrews 11:16) and an eternal Hell to be avoided (Re...

Radio: Early History
Radio: Early History Presentation Dialogue SOLAR ENERGY. All life on Earth depends on energy from the sun. Solar energy is the source of energy for photosynthesis. It provides the warmth necessary for plants and animals to survive. The heat from the sun causes water on the Earth's surface to evaporate and form clouds that eventually provide fresh rainwater. Solar energy is the result of thermonuclear fusion reactions deep within the sun. These reactions produce so much energy that they keep the ...

Fahrenheit 451
Fahrenheit 451 Ray Bradbury's satire, Fahrenheit 451, is a novel full of symbols criticizing the modern world. Among those symbols appears The Hound. The Hound's actions and even its shape are reflections of the society Bradbury has predicted to come. Montag's world continues on without thought; without any real reason. There is no learning, no growth, and no purpose. The Mechanical Hound slept but did not sleep, lived but did not live in its gently humming, gently vibrating, softly illuminate...

Gas
Gas And Electric Cars As his car warmed up that morning, Alan Wilson stared with amazement at his gas gauge. I can't believe it's on ?EMPTY' again, he ranted. I just spent twenty bucks last weekend! Alan sped away from his home toward the gas station before he had to be at work that morning only to find out that the gas prices had been raised again. Why don't I just burn my money? he said facetiously. Alan grabbed the nozzle and began the weekly task of filling up the gas tank on his 1970...

Recycling
Recycling In the United Sates, where the population is inflated every year. The amount of space for landfills decreases every day. The need for recycling should not be asked, it should just be done out of habit.
