Alchemy -the Predecessor Of Modern Chemistry There are many ways to examine the subject of alchemy, including alchemy as a source of symbolism, psychology, and mysticism. It has also been an influence on the world view of various writers, artist, and musicians. The focus of this report is alchemy as a pre-chemistry, which gave a new impulse towards the preparation of medicinal remedies and also was a major influence on today\'s scientific investigations.Alchemy is an ancient art, practiced in th

Mechanical Engineers A mechanical engineer works with the principles of motion, energy and force. Usually a machine changes one form of movement into another. Mechanical engineers design machines whose parts work in a safe, reliable and efficient way. Mechanical engineers apply scientific method to find the answers to mechanical problems. Many laws and principles developed by scientists are used every day by the mechanical engineer. Mechanical engineers contribute to many industries and occupati
The Fear of Science To live in the today\'s world is to be surrounded by the products of science. For it is science that gave our society color television, the bottle of aspirin, and the polyester shirt. Thus, science has greatly enhanced our society; yet, our society are still afraid of the effect of science. This fear of science can be traced back to the nineteenth century where scientist had to be secretative in experimenting with science. Although science did wonders in the nineteenth centur

Marie Curie In her pioneering way, Marie Curie decided, in 1897, to take a physics doctorate. Henri Becquerel, who was studying X-rays, had recently observed that uranium salt left an impression on a photographic plate in spite of its protective envelope. What better subject could there have been for Marie than to try and understand the effect, the energy of these uranic rays? Pierre consented. And so his frail wife set about her work, handling tons of minerals; she noted that another substance,

Effects Of Altitude On Human Physiology The Effects Of Altitude On Human Physiology Changes in altitude have a profound effect on the human body. The body attempts to maintain a state of homeostasis or balance to ensure the optimal operating environment for its complex chemical systems. Any change from this homeostasis is a change away from the optimal operating environment. The body attempts to correct this imbalance. One such imbalance is the effect of increasing altitude on the body\'s abilit
high academic standards An Avenue to High Academic Standards By Lynn Olson In her article An Avenue to High Academic Standards, Lynn Olson argues that A prominent misconception surrounding school-to-work is that it downplays intellectual achievement, and that school-to-work can encourage young people to pursue education and training beyond high school. A school-to-work program enables a student to go to a regular school and attend classes just like any other regular high school student, bu
The History Of Arts And Crafts O The distinction between ‘Craft\' and ‘Design\' can be at times problematic explain what you understand these terms to mean, and illustrate their application in relationship to the work of one practitioner. The definition for craft is, the making of decorative or functional objects, generally by hand. Hand and power tools may be used, however, in making some craft items. The term crafts also refers to the objects made. The function of crafts is generally conce

Historical Development Of Atomic Structure Historical Development of Atomic Structure Yazan Fahmawi Sept. 30, 1995 T3 IBS Chemistry Ms. Redman The idea behind the atom goes back to the Ancient Greek society, where scientists believed that all matter was made of smaller, more fundamental particles called elements. They called these particles atoms, meaning not divisible. Then came the chemists and physicists of the 16th and 17th centuries who discovered various formulae of various salts and water
Einstein a plagiarist ? Abstract Proponents of Einstein have acted in a way that appears to corrupt the historical record. Albert Einstein (1879-1955), Time Magazine\'s Person of the Century , wrote a long treatise on special relativity theory (it was actually called On the Electrodynamics of Moving Bodies , 1905a), without listing any references. Many of the key ideas it presented were known to Lorentz (for example, the Lorentz transformation) and Poincare before Einstein wrote the famous 1905
drugs in society With the use of drugs being such a controversial issue in today\'s society we felt as a group it was important to further explore this issue. As we possess a high interest in how drugs affect a number of social groups. These groups of course range from young teens to high-class older individuals who will have different reasons and different acceptable standards of behaviour. The question that is being explored in our presentation asks what drugs are doing to our society. This me
Brave New World-allusions Allusions to the Brave New World 1. Ford Henry Ford (1863-1947) revolutionized the automobile industry with the assembly line method of production, which proved very successful for 15 million Model Ts were sold. Humans were similarly produced in the Brave New World where the embryos passed along a conveyor belt while a worker or machine would have a specific task dealing with the specimen. Again, this assembly line method proved very successful. 2. Lenina Vladmir Leni
Multiple Personality Dissorder Multiple Personality Disorder (MPD) or Dissociative Identity Disorder (DID) was first acknowledged in the 1700\'s but was not understood so therefore it was forgotten. Many cases show up in medical records through the years, but in 1905, Dr. Morton Prince wrote a book about MPD that is a foundation for the disease. A few years after it was published Sigmund Freud dismissed the affliction and this dropped it from being discussed at any credible mental health meeting

Louis Pasteur Louis Pasteur was an example of a truly gifted person who made many wildly diverse discoveries in many different areas of science. He was a world-renowned French chemist and biologist whose work paved the way for branches of science and medicine such as stereochemistry, microbiology, virology, immunology, and molecular biology. He also proved the germ theory of disease, invented the process of pasteurization, fermentation, and developed vaccines for many diseases, including rabies.

Hume on Sentiments and Reason In Appendix I., Concerning Moral Sentiment, David Hume looks to find a place in morality for reason, and sentiment. Through, five principles he ultimately concludes that reason has no place within the concept of morality, but rather is something that can only assist sentiment in matters concerning morality. And while reason can be true or false, those truths or falsities apply to facts, not to morality. He then argues morals are the direct result of sentiment, or th
Cold Fusion Cold Fusion: The Continuing Mystery In March of 1989, a discovery was made that rocked the scientific world. Stanley Pons and Martin Fleischman had announced that they were able to create and sustain a cold fusion process. After intense media attention, and corresponding interest in future test, the subject seemed to have faded away. Future tests proved inconclusive, and when the quick promise of easy energy didn\'t materialize, most quickly forgot the subject. Little is said about t
An Explanation Of Terrorism An Explanation of Terrorism After browsing through Stephen E. Atkins book Terrorism, I soon learned many interesting things regarding the history of terrorism. It seems this form of protest has been around since Biblical times. Also, the main goal of a terrorist is not to do damage to one peticular person or place, but to gain publicity for an idea they support. (page 1) Evidence of this can be found by looking at the recent past of the United States. The Oklahoma bom
Premature Specialization Premature Specialization A medical doctor in today\'s world is educated and trained in a traditional manner that seeks to insure the well being of his or her patients. Practicing medicine requires a strong science background and rigorous training; it is in the interest of clients and medical boards across the world to assure this. Thus, education in the science field is extremely important, even at the undergraduate level. Being a doctor is not just a job, nor is it sole
DOES LIFE HAVE A MEANING Does life have a meaning? Life, it might be argued, is the distinguishing feature of all organisms and may most usefully be thought of as involving various kinds of complex systems of organization providing individual organisms with the ability to make use of those energy sources available to them for both self maintenance and reproduction. Underlying this deceptively persuasive definition, however, lie those persistent traditional problems inherent in the search for an
Martian Rocks H. G. Wells wrote in his book, War of the Worlds , about Martian invasion toward earth. He mentioned, No one would have believed, in the last years of the nineteenth century that this world was being watched keenly and closely by intelligences greater than man\'s and yet as mortal as his own; that as men busied themselves about their various concerns they were scrutinized and studied, perhaps almost as narrowly as man with a microscope might scrutinize the transient creatures that
Dead Poets Society Literary Essay - Dead Poets Society #9;Bill Beattie once said, quot;The aim of education should be to teach us how to think rather than what to think - rather to improve our minds, so as to enable us to think for ourselves, than to load the memory with thoughts of other men. quot; All too often, however, individual thoughts are crushed by the powerful weight of conformity. In the film Dead Poets Society, conformity exercises it\'s influence and the results prove disastrous for

I did not, however think it was very different than I had imagined it would be like. Although my opinion would have been much better if I saw it live, it was a great first impression. I thought that all of the characters were very well casted. I did think that even though they were all very talented singers, they could have used more facial expressions

Drugs And Abuse Psychology: Drugs And Abuse Drugs and Abuse Abuse of drugs can have effects on the user even after the use of drugs has stopped. Different drugs produce different effects, depending on the user, type of drug, and severity of abuse. New research is done every day in the area of drug abuse that makes finding accurate results on the broad topic of drug abuse very difficult. From the most recent studies only can one find data that is presently accepted as correct. These numerous stud

The Wonderful State of Memory The Wonderful State of Memory Primo Levi, in The Drowned and the Saved, expresses theories of memory. My objective is to prove that Primo Levi\'s theories of memory being transitive and selective are correct. I will do this by examining and critiquing not only Levi\'s perspective on memory, but also those of other philosophers and psychoanalysts whose work explored the subject. Writer and chemist, survivor and witness, Primo Levi was born in Turin, Italy, in 1919. L

Math Of Nature Or Math For Nature Math is one of the basic sciences of life; it can be said that is the most basic science, the first thing a person learns, apart from reading and writing, is how to add and subtract. But, is math a part of nature, or was it made to measure or understand nature? It is really hard to know, but in my point of view, math is a method created by men to measure nature. If math was a part of nature, man would be born with math knowledge, but man is not, man had to think
