“The Discoveries of Archimedes” Archimedes truly was a man ahead of his time. He forever changed the face of mathematics and one of his discoveries even helped change the face of the earth. Archimedes proved the law of the lever and invented the compound pulley. He reportedly once told King Hiero, king of Syracuse: “Give me a place to stand on, and I will move the entire earth.” The king challenged him to prove his boast. It is said that he moved a ship full of passengers

If the nation is serious about the manned exploration and development of space, then more attention must be focused now on research to study how weightlessness and reduced gravity would affect everything from power production to plumbing. The research is critical for the development of space-related technologies. There are certain scientific and engineering problems of a fundamental nature that need to be addressed before these technologies can be developed. This research should be done now b

The Physics of Flight One of the most novel forms of physics is that of aerodynamics, the study of flight and the effects of gases over an airfoil. The study of aerodynamics was furthered by a few discoveries, like gravity, the laws of motion, and the creation of molecular physics. One of the most significant physical laws that led to the creation of the airfoil is the Bernoulli Principle, which states the relationship between pressure, fluid flow velocity, and the potential energy of fl

Lunch Time Conspiracy Lunch time is a conspiracy orchestrated by the New World Order. The purpose of it is to force more falsified concepts and theories into are puny minds. The links and reasons behind it are clear. The New World Order wants to keep us down and prevent us from discovering the truth. This is an election year. George Bush Jr. is the Republican nominee for presidency. George Bush Jr. s father, former president George Bush, is the leader of the New World Order. Former pr

Albert Einstein was known for The Theory of Relativity (E = mc^2) which in based on twoprinciples:I. Principle of Special Relativity- All inertial observers are equivalent.II. Constancy of Velocity of light- The velocity of light is the same in all inertial systems. Albert Einstein was born on March 14th in Ulm, Germany. His mother was shocked to find out that he had a very big head. In the years to come she found out he had a big head because he knew more than the average person did, his

Newton's Three Laws of Motion Isaac Newton was born on Christmas day in 1642, in Lincolnshire, England. Newton attended Trinity College in 1661 and had both his Bachelor of Arts and his Master of Arts by 1669. That same year he became the associate of the French Academy of Sciences. He was elected to Parilment, then appointed a warden, and finally, President of the Royal Society. Newton was a master of science and mathematics. He discovered calculus, before Leibniz became popular. Perhaps Ne

Stars and galaxies began to form about one billion years following the Big Bang, and since then the universe has simply continued to grow larger and cooler, creating conditions conducive to life. Three excellent reasons exist for believing in the big-bang theory. First, and most obvious, the universe is expanding. Second, the theory predicts that 25 percent of the total mass of the universe should be the helium that formed during the first few minutes, an amount that agrees with observa

Black Holes If theories of their existence are true, black holes are the most powerful force in the known physical universe. Many people are familiar with the term black hole, but few people actually know anything about them. A black hole forms as a result of a massive star running out of fuel to burn (Chaisson, 193). Once the star is no longer exerting outward force by burning off gases, it begins to collapse under it's own intense, inward gravity (Chaisson, 193). It is like slowly le

Gravity is really an unknown force. We can define it as a field of influence, and that it effects the entire existence of the universe. Some people think that gravity consists of particles called gravitons, which travel at the speed of light. The only thing we do know is how gravity operates in different parts of our universe. Without gravity, there would be no space and time. There is a legend that says that Galileo once dropped two objects off the Leaning Tower of Pisa to show that the heav

This didnt get a very good grade but it works to help set it up. Cycloids, Brachistochrones, and other Archaic Words Introduction: Everyone with a decent math background knows that a straight line is the shortest distance between two points. Intuitively, many would think that it would also be the path taken that took the shortest amount of time. We will show that the time that it takes to traverse cycloidal and elliptic path is faster than that of a straight line. We will do this by usin

With all the excitement surrounding the new Star Wars movie, it is a big day for lovers of science fiction. But how much does the average person really understand about beaming up; phasers and photons; wormholes and warp drive? How powerful are these fantasies compared to the real thing? If theories of their existence are true, black holes are the most powerful force in the known physical universe; however, do they even exist? Most scientists believe so, but by their very nature, black holes a

What exactly IS a black hole? With all the excitement surrounding the new Star Wars movie, it is a big day for lovers of science fiction.

Once the star is no longer exerting outward force by burning off gases, it begins to collapse under it s own intense, inward gravity (Chaisson, 193).

The End of the Universe There are many theories predicting how the universe will end. These theories are based on one four basic principles. The first principle being that the universe continues in an endless cycle. The next is that the universe will stay at its current size. The third is the universe will continue to expand endlessly. The final principle, states that the universe will collapse on itself. The first theory is based on the fact that the universe is oscillating. The un

Physics is everywhere in the world of sports. It can be found when a boxer punches a guy, or when a person is stabbing something. The shot put is an event which has many practical applications to physics. From the time the thrower begins moving, to the time the shot hits the ground, physics can be applied. The first track and field events began over two thousands years ago in Greece. People participated in sprints, endurance races, shot put, and discus. Track and Field events were held first

Drop Zone: Drop zone is 224 feet high. The ride takes a total of three seconds to fall. Assuming that the ride is in total free fall, the ride is accelerating the most at the point right before it begins to slow down or decelerate. Its greatest speed is 62 mph and the point of the ride's greatest instantaneous speed is right before it begins to slow down. The calculated instantaneous speed just before it stops is 62 miles per hour. If you were to put a penny on your lap before the ride d

Aristotle It's neat how the universe works. Through out our existence we had our pros and cons. The way we dealt with problems was with or knowledge that we had with our experiences in life, we developed some theories and methods to find the answer to any major questions we had in life. We still have not yet figured every answer to all or problems but every day, every week and every year we are getting closer and closer. What are some of the questions we ask ourselves and what are some of

The trebuchet is a medieval siege weapon that was used to hurl rocks over an enemy wall. However, its basic design has been recently rediscovered since the Middle Ages. In fact, the trebuchet has begun to exist in abundance in several places. For example, people have taken it up as a hobby to build and some colleges, such as West Point, it has used it in engineering courses. As I researched for this report, I found many personal web sites for building trebuchets. There were several p

Stephen William Hawking was born on 8 January 1942 in Oxford, England. When he was eight, his family moved to St Albans, a town about 20 miles north of London. At eleven Stephen went to St Albans School, and then on to University College, Oxford which was his father's old college. Stephen wanted to do Mathematics, although his father would have preferred medicine. Mathematics was not available at University College, so he did Physics instead. After three years and not very much work he was awa

Thomas Alva Edison was born February 11, 1847 in Milan, Ohio. When he was 10 he had set up a small chemical laboratory in the cellar of his home after his mother had given him an elementary physical science book. He had found science very interesting and soon operated a homemade telegraph set. In 1868 he got a job in Boston as an expert night operator for Western Union Telegraph Company. He had borrowed a small sum from an a friend and gave up his job in 1868 and became a free-lance in

Thomas A. Edison: Fact or Fraud? Thomas Edison was born February 11, 1847 in Ohio. He moved to Michigan at age 7 and went to school there. One teacher thought he was very dumb because he asked too many questions and never understood anything. He did home school and tried other public schools but never did too well. At age 12 he was selling candy and newspapers at a train station. Thomas Edison started off right away on the right path. That path is to get things done quickly and go fu

Edison was born in the village of Milan, Ohio, on Feb. 11, 1847, and his family later moved to Port Huron, Mich. In his early life as a kid he played jokes on people and got into trouble. One time he set his father's barn on fire because he wanted to see what fire look like when it burned. His schooling was three months long because he quit when too many people made fun of him. At the age of seven his mother taught him, and he loved to read books. The book Schoool of Natural Philosoph

As the end of the 20th century becomes closer each day, some of us will think back of the good times and memories they've had. Some of us may even think of the great leaders or people that have impacted their lives and the world. People such as Martin Luther King, John F. Kennedy, or maybe even Bill Clinton are a few of the many people that might cross your mind. There is one person you will know for sure before you leave here today because he was considered the greatest inventor in h

A contributing factor to the story "The Doll's House" by Katherine Mansfield is the characterization of Kezia as she travels in her innocence through the symbolic world of experience. Kezia is essential to the plot because she represents a taboo, offering opposition to common ways of thinking. Through the portrayal of Kezia, as she interacts as the symbolic eccentric, Mansfield emphasizes the powers and blind justification of conformity within a society. The story commences with the arrival o

“Suicide is a permanent solution to a temporary problem.” I feel that it isn’t the right solution, that there are other options. This is one reason why I chose teen suicide as my I-search topic. I have had personal experience with teen suicide involving my friends, and the next time that one of my friends comes to me saying, ”I want to die.” I want to be able to understand where they are coming from and how I can help them. I also chose this topic because I want to educate o

Suicide can best be described as the destructive act of voluntarily taking one’s own life. Suicide often presents a real and often tragic puzzle to be solved by friends and family, and any other professionals who have been involved with someone who has committed suicide. To be able to definitively answer the question as to why an individual would commit such a deadly act seems to be a highly complex task. The victim himself or herself, is perhaps the least aware of the answer to t

Background Knowledge Resistance, in electricity, is a property of any object or substance to resist the flow of an electrical current. The quantity of resistance in an electric circuit determines the amount of current flowing in the circuit for any given voltage applied to the circuit. The resistance of an object is determined by the nature of the substance of which it is composed, its resistivity, accounting for its dimensions and its temperature. Resistivity is expressed in terms of Ohms

Keith Griswold March 13, 2000 Exp. Physical Chem. Dr. Humphrey Heat-Capacity Ratios for Gases Cp = Cv + R The ratio, Cp =  Cv is related to the ability of the gas to do expansion work. Heat capacity at constant volume, Cv can be described using the equipartition theory, which states that each mode of motion will contribute to a molecule or atom’s energy. E = E(translational) + E(rotational) + E(vibrational) Setting up a Cartesian coordinate system, translational

The idea for the laser started as long ago as 1905 when Albert Einstein suggested the simulated emission of light. Light sources ie. candles, florescent substances, torches, and light bulbs give of packets of energy, called photons, when their atoms are excited by energy. Einstein suggested that these atoms could be artificially stimulated to emit photons, where the light produced would be highly concentrated, bright and powerful and could be used for many tasks. Even though Einstein new the p

Carbon Dioxide Lasers Carbon dioxide lasers are one of the most powerful lasers ever constructed. The word “LASER” stands for Light Amplification by Stimulated Emission of Radiation. Lasers are devices that amplify light and produce light beams, ranging from infrared to ultraviolet. A light beam is consistent when its waves or photons, increase while mixing together. Laser light can be extremely intense, highly directional and very pure in color. Gas lasers such as the carbon dioxi

INTRODUCTION Holography is a method of obtaining three-dimensional photographic images. These images are obtained without a lens; the pattern recorded on a photographic plate is called a hologram. On the other hand image formation refers to the process of producing and refining images, various methods are used in order to achieve this. Some common examples include the use of double lens optical systems, spatial filtering, matched filtering and phase contrast microscopy. An exhaustive treatme
