From the Paper
" Lise Meitner (1878-1968) overcame extraordinary odds to become one of the great physicists of the twentieth century. At a time when Austrian women were denied higher education and during a later time when Jews were persecuted and murdered, Meitner managed to obtain her doctorate and lead an extremely successful professional life. Her private life centered around her friends, many of them colleagues, and she did not marry or have, so far as is known, any romantic involvements. Politics and other circumstances denied her some of the rewards and the professional continuity that her achievement entitled her to enjoy. And, late in life, she was also distressed (even after having failed to get full credit for her role in the discovery of nuclear fission) to be identified with the development of the atomic bomb. Meitner, however, always said that she was very..."

Abstract
Lightning is a natural phenomenon that is dramatic, often beautiful, and yet deadly and dangerous at the same time. A bolt of lightning involves the rapid discharge of a massive amount of electrical energy producing both the bright flash of light and the sound of thunder

From the Paper
"Lightning is a natural phenomenon that is dramatic, often beautiful, and yet deadly and dangerous at the same time. A bolt of lightning involves the rapid discharge of a massive amount of electrical energy producing both the bright flash of light and the sound of thunder. There are a number of different kinds of lightning produced by different conditions, and new information on lightning is discovered all the time. By its nature, lightning is an ephemeral phenomenon, making it difficult to study under all conditions and explaining why new types of lightning have been found as man makes his way higher and more often into different regions of the upper atmosphere. Lightning is an extremely common natural phenomenon. Since Benjamin Franklin demonstrated the electrical nature of the lightning bolt, lightning has been subjected to many scientific studies."

"The Tao of Physics" ( Fritjof Capra ), 1997.
Reviews work on practical & conceptual connections between modern science & mysticism, Western & Eastern approaches to reality, focusing on the need for balance between the two.

From the Paper
"The search for knowledge in the West today is based very much on the scientific method and on rational inquiry, and this is often contrasted with the way of knowing in Eastern mysticism. The two means of ascertaining knowledge are normally considered to be far apart, but in Fritjof Capra's book The Tao of Physics, parallels are found between the two approaches which show that the insights of modern physics actually offer more explanation for certain elements of mysticism. The conclusion is that as the people of the world try to educate themselves in the sciences, they would do well to educate themselves in and to practice spiritualism and mysticism as well and so to gain insight from both ways of knowing.

Different cultures produce their own particular way of structuring the world they see around them. They use religion.."

From the Paper
"The engineering definitions, methods of analysis, and significance of many elements of the study of fluid mechanics are presented.

Definitions and Fluid Properties
Fluids can be either liquids or gases, and fluid mechanics "refers to the study of the behavior of fluids, either at rest or in motion." Nunn elaborates that there are "two main physical properties defining a fluid: density and viscosity." Nunn then subdivides fluid mechanics into three major categories of ideal fluid flow, in which density is constant and viscous effects are negligible; compressible flow, in which density varies from place to place throughout the fluid and viscosity effects are trivial or..."

» Click here to show/hide summary

Abstract
The paper defines black holes and explains what they are made up of. The paper explores common misconceptions surrounding black holes, as well as other mysteries. Finally the paper examines theories regarding how black holes eventually end.

From the Paper
"Black holes, one of space?s greatest phenomenons, appear to be tremendous concentrations of matter, usually at the center of a galaxy; however, smaller back holes are possible. The matter is in the form of neutrons, protons, and electrons, tightly packed together by their mutual gravitational attraction. The beautifully descriptive name comes from the fact that light cannot exit from a Black hole. They are suspected to form in the death and collapse of a star that began with more than10 times the sun's mass (those with less mass become white dwarfs or neutron stars)."

Albert Einstein, 2001.
Discussion of what makes him a modern hero; his scientific methods & achievements, his humanitarian efforts; early life & shaping of his character.

From the Paper
"This paper will discuss what makes Albert Einstein a hero. Webster's Ninth New Collegiate Dictionary gives several definitions of a hero, most of which apply to Einstein. According to Webster's a hero is a mythological or legendary figure endowed with great ability; a man admired for his achievements and noble qualities; the central figure in an event, period or movement; and an object of extreme admiration and devotion. These definitions can be readily applied to Einstein who was indeed a hero of the world community. Unlike heroes of legend, however, Einstein was a modern hero.

In naming Albert Einstein A Person of the Century@ TIME Magazine wrote for Einstein to become a modern icon, especially in America, required a total revision of the definition of a hero."

» Click here to show/hide summary

From the Paper
"The Nobel Prize is perhaps the most coveted recognition of excellence in a given field. In 1997, the Nobel Prize in Physics was given to Professor Steven Chu of Stanford University along with two of his colleagues, William D. Phillips and Claude Cohen-Tannoudji. The contributions of these three men mounted over the span of more than a decade of research and experimentation, culminating in the development of groundbreaking new methods to cool and trap atoms with laser light.
Steven Chu has been an avid Physics enthusiast ever since his high school days in Garden City, New York, where under the tutelage of his Advanced Placement Physics teacher he was given his first taste of genuine lab experience(College Board Online, 1998)."

Black Holes, 2002.
A discussion on the existence of black holes.
1,392 words (approx. 5.6 pages), 5 sources, APA, £ 28.95
» Click here to show/hide summary

Abstract
This paper discusses how black holes are created. It studies the ideas of physicist John Mitchell, his discoveries and how Isaac Newton's physics ideas helped lead to his discoveries on black holes. It also covers white dwarfs (stellar corpses), the most famous being Sirius.

From the Paper
"The black hole was first named by the English physicist John Mitchell in 1783, more than two hundred years ago. But what are these black holes? Do they really exist? Based on planet movement studies made by Tycho Brahe and Johannes Kepler, John Mitchell deduced the existence of a force that made the Sun, the Earth, the Moon and everything contained in the cosmos."

Abstract
This paper explores methods used by astronomers to measure the universe, the dual nature of light, origins of the universe and the solar system and types of stars. It also discusses planets and other celestial bodies.

From the Paper
"Another way to measure the universe is using shadows. Some astronomers observe ?dark silhouettes cast by distant clusters of galaxies (Glanz,1999)? against the ?cosmic microwave background radiation (CMBR) (Glanz, 1999)? The glow from this radiation provides a back light that helps measure the size of the shadows. The CMBR was formed back when the cosmos were only 100,000 to 300,000 years old. Because of the CMBRs? age, ?everything in the visible universe lies in front (Glanz, 1999)? of it. When the radiation started out, it had hot temperatures due to the universe just being formed. However, as the universe expanded, the temperatures cooled. This gives astronomers additional information to aid them in their measurements."

Heat Transfer Mechanisms, 2002.
An introduction to heat transfer, including a description of convection, conduction and radiation.
1,560 words (approx. 6.2 pages), 7 sources, MLA, £ 31.95
» Click here to show/hide summary

Abstract
This paper briefly describes the different forms of heat transfer. Heat transfer is a process that occurs on the molecular level. The basics of the process are defined, with three heat transfer mechanisms identified-- conduction, convection and radiation.

From the Paper
"In metals, thermal energy is transported by conduction band electrons. This is based on understanding molecular orbital bands. This refers to solids that form a lattice, including metals. These lattice metals are understood by looking at the lattice itself as one large molecule rather than looking at it as individual atoms. The electron orbitals of the atoms overlap, creating a continuous band covering a range of energies that extends throughout the lattice (Shriver, D.F., Atkins, P.W., & Langford, C.H. Inorganic Chemistry. New York: Oxford University Press, 1994, p. 91)."

From the Paper
"Math is the language of science. The different disciplines of math relate to different areas of science. Science needs math in order to be understood. Algebra allows us to create sentences using numbers to describe an event. Geometry and Trigonometry help us to describe shapes, and Calculus is the tool for describing change. It can be a change in angles as in vector calculus, a change in rate, a change in speed, or almost any other change."
