Abstract
The space shuttle is the world's first reusable spacecraft. With today's technology, shuttles are capable of withstanding the vacuums of space, the difficulty of re-entry and cosmic and solar radiation. The paper shows that while some scientists believe the space industry will never become commercialized due to the shuttle's outdated complexities, shuttles of today may commercialize the space industry with an old rocket technology that has not been fully realized. Solid rocket engines, an old, yet reliable, space technology, are safe, low cost, provide a high thrust and may be the key to space industry commercialization.
From the Paper
"Solid fuel rocket engines are an old technology. While they have changed since their inventions of early China, their simple and non-complicated design remains in tact. It is due to that design that the engines and rockets have remained stable throughout centuries. They are safe, encompassing easy to handle materials, and allowing for long-term storage. They are reliable, consisting of non-machine related parts to limit the possibilities of mechanical failure. They are cost effective, due to their reusability as well as their materials, made from low cost resources."

Abstract
This paper explains that by viewing the gas that surrounds stars as a dynamic atmosphere, undergoing cycles of materials similar to those that go on in the Earth's own protective gases, astronomers are understanding more and more about the processes involved in the formation of stars. The paper deals with the questions of how the supernova of massive stars affect the formation of stars in the future, why star formation seems to occur in relative bursts, and how long the Milky Way will continue to produce stars.
From the Paper
"Beyond applying the atmospheric model to intergalactic gas, astronomers have also been studying more carefully exactly what components make up the gas and at what temperature these components exist. About 90% of the constituents of intergalactic atmosphere are various forms of hydrogen, with close to 10% being helium, and everything else, from lithium to uranium -- the whole spectrum of the periodic chart -- making up less than 0.1%. The majority of the hydrogen is present as neutral hydrogen, termed H I by astronomers. This form of hydrogen gas is identified by the spectral frequency of the light that it emits, namely 1,420 megahertz. Although scattered throughout the galaxy, the majority of H I is located around the galactic midplane, and forms a gaseous disk about 300 parsecs thick (Reynolds, 2002, p. 40)."

Abstract
This paper looks at black holes in terms of the most prevalent theories. It first, defines what we have come to understand as a black hole. It then touches upon how black holes are documented and measured. Thirdly, it examines the black hole believed to be at the center of our own Milky Way galaxy. Finally, it explores the prevalent hypothesis that black holes are in fact the genesis of all galaxies.
From the Paper
"Gravity is the cause of black holes. A black hole is the unlimited and irresistible force of ultimate gravity in the universe. To understand how a black hole is created, it is helpful to understand a bit about the basics of gravity. Imagine shooting an arrow into the sky. The harder you shoot the arrow, the farther it will go in attempting to escape the pull of the Earth's gravity. If you were to use a big enough bow with enough force you could help the arrow reach speeds exceeding 7miles per second which is the escape velocity for the Earth. Escape velocity indicates the minimum speed necessary to beat the pull of the planet's gravitational core (Cowen , 390). The strength of the gravitational pull of the core is determined by the density and mass of the core. The denser and more massive that the core is, the greater the gravitational pull. If you were to drop a ball to the center of the earth, the gravitational forces would crush it into an ever shrinking volume requiring even greater amounts of force to help it reach escape velocity. As the greatest theoretical speed for any physical object in the universe is that of light (which travels at 186 thousand miles per second) a mass large and dense enough can actually exert so much force that not even light can achieve escape velocity. The object that can pull even light into it and keep it from escaping is a black hole."

Abstract
This paper is an examination of Mayan architecture which emerged from the rainforests of Guatemala and Yucatan. The writer maintains that the detailed architecture was a fitting monument to the highly sophisticated civilization that existed in the region before the Spanish arrived. This look at the style of Mayan architecture includes a diagram highlighting the areas of construction in Copan. The paper argues that Mayan culture was more than a collection of buildings in that every aspect of architecture was linked to the sacred world around. In conclusion the writer explains that the temple pyramid which symbolizes Mayan architectural skill is also a statement of their cosmographic ideas. Everything has a beginning and end. Everything is the beginning and the end.
From the Paper
"Deep in the tangled rainforests of Guatemala and the Yucatan, the Maya made some of the greatest contributions to world architecture. Their stone cities complete with temples, palaces, tombs, and ball courts are fitting monuments to the complex, and highly sophisticated civilization that existed in these regions many centuries before the arrival of the Spanish. Mayan priest-astronomers made elaborate calculations to catalog the passage of time. Great warrior kings immortalized themselves and their deeds on stelae, recording for future generations the contributions they had made toward maintaining the cosmic order. The Maya were the only Pre-Columbian people to ever have invented a complete system of writing".

Abstract
This paper begins by providing a brief biographical overview of Isaac Newton, from his birth in England in 1642 to his groundbreaking scientific theories and discoveries. The paper covers Newton's scientific achievements, starting with the fact that he established a unified theory of approach to modern science. It discusses his discoveries relating to the white light, the telescope and to the field of optics in general. The paper also covers Newton's mathematical achievements in the form of calculus and his most famous discovery of all - gravity.
From the Paper
"Newton's discoveries in optics were offset by his even more groundbreaking discoveries in pure mathematics and the science of mechanics. One of the most important modern mathematical tools 'The Integral Calculus' was the brainchild of Newton. It need not be mentioned that without this mathematical tool the progress that the scientific community achieved in many disciplines would have been significantly delayed. However Newton's discoveries in the field of mechanics outweigh all his other accomplishments. Though Galileo had already discovered the first law of motion his theory was based on the movement of objects without any external influence or attraction between them. Newton's three laws of motion explained the hitherto inexplicable behavior of all physical bodies in motion. Still more astounding was Newton's discovery of gravity. All these four laws put together explained the mechanical motion of all earthly and heavenly bodies. Newton not only proposed these laws but also ratified them by using the integral calculus."

Abstract
This paper analyzes the history of illusions and the effect they have had on the intellectual development of the western world. The paper discusses the roots of the problem of the moon allusion in philosophy and the crossover into psychology. An outline is presented of what the moon illusion is, illustrating the issues of size and distance of the moon. The paper provides some of the common responses to the moon allusion by people like Baird and Wagner, Kaufman and Rock, Parks, and Reed. The implications for both science and philosophy for the various outcomes achieved by the researchers are examined.
From the Paper
"Open up any philosophical text, from the elementary textbook, Does the Center Hold? by Donald Palmer to the Oxford History of Western Philosophy. The first entry in the book will be Socrates. Even as far back as that, and probably further back than that, people have been concerned with the problems of perception. Idealism, realism, skepticism. How do we know what we know when the world can change so frequently, so fast. If our senses sometimes deceive us, and they tend to deceive us often, how can we rely upon them to tell us about the outside world. Perhaps it was when these questions were first posed that the science of psychology was first born."

From the Paper
"In outer space there are many things that man is still trying to fathom, and he has been intrigued by many things high up in the sky, but yet has not been able to figure out what they are or what they may mean. The field of astrology is one that began thousands of years ago with the Egyptians being the first known astronomers. They were the ones who created the first map of the North Star that is used till today to trace the movements of our planet and the heavenly bodies around it."

Abstract
The paper argues the scientific big bang theory and order in the development of our universe. It describes the hierarchy of events and the Great Chain of Being theory. In particular, it discusses the electron atom nucleus universe expands origin universe Big Bang primordial ball creation overall order. This paper is well formatted with intelligent depth to the argument of the creation of life and our planet.
From the Paper
"Electrons circle the nucleus of an atom. Untold trillions of atoms collide together and explode. The universe expands. Electrons race down the copper wires of an electric cable. The sun shines. Leaves digest the sunlight, produce nutrients, live, grow, die, and fall to the ground. The wind bears aloft the leaves, scatters them over earth and sea. The tide moves them, pushes them up into rivers where at last they settle into the mud. Salmon swim upstream; lay their eggs on the muddy bottoms of lakes and rivers. A powerful grizzly bear nuzzles the icy water of a mountain brook. His great paw sweeps into the water and catches a darting salmon. Men come; establish a city on the banks of the stream. They drive the bear off. Their boats coast upon the surface of the sparkling water. Nets plumb the frigid depths, resurface filled with salmon. The men eat the salmon. The salmon are digested, turned into fodder for a thousand other creatures and into the food that builds civilizations. Digested again, these minute particles break down into molecules, and the molecules into atoms. A lone atom floats off in the vast emptiness of space. Electrons circle the atom's nucleus. These are cycles, yes, but wherein lays their ultimate origin? Is there a connection between all that makes up the universe? Is there a plan?"

Black Holes, 2002.
A study of the subject of black holes.
2,045 words (approx. 8.2 pages), 7 sources, APA, $ 64.95
»
Click here to show/hide summary
Abstract
The paper describes a black hole as a region of space that has so much mass concentrated in it that there is no way for a nearby object to escape its gravitational pull. Black holes are thought to be formed from stars or other massive objects when they collapse from their own gravity to form an object whose density is infinite. This paper covers the topic of black holes including definition, origin, history and size.
From the Paper
"In the 1930s, researchers began to prove that black holes may actually exist. They showed that when a sufficiently massive star runs out of fuel, it is unable to support itself against its own gravitational pull and should collapse into a black hole.
"The term "black hole" was coined by physicist John Archibald Wheeler coined in the 1960s. So why did Wheeler choose to call them black holes? The main reason was since no light can escape from inside a black hole, it seemed logical. Before Wheeler invented the term, black holes were commonly referred to as "frozen stars." "

Abstract
This paper is introduces and discusses features of the Martian terrain suggesting that water, and possibly life, may have been present in the distant past or that water exists today under the planet's surface. Conclusions about this suggestion are made at the end of the paper.
From the Paper
"The public's fascination and with the red planet originated with Percival Lowell's book, "Mars," published in 1895. Although Schiaparelli and others had discussed the possibility of Canals on Mars, Lowell's drawings and his suggestion of intelligent life on Mars thrilled the public."

Abstract
This paper begins with a brief look at the history of the relationship between the U.S. and the U.S.S.R. It then discusses the roots of rocketry and the birth of modern rocket science. A discussion of the race between the two nations to put a human being into space during the 1960s follows.
From the Paper
"The contest for space explodes into life within the saber rattling environment of the nuclear age. Near the end of the 1950s, the cold war had escalated to frightening proportions. Both countries maintained enormous stockpiles of nuclear and conventional weapons. The United States developed its deterrence based on long-range bombers. By 1955 the US Air Force had "580 B52s, and 1500 B-47s,"(NASA) all 2080 aircraft capable of delivering nuclear weapons. In 1955, the United States Navy launched the world's first nuclear submarine. By 1960, the US had over 18,000 nuclear weapons in its arsenal, and developed the liquid fueled Atlas and Titan Intercontinental Ballistic Missiles (ICBM)."

Abstract
In this article, the writer notes that one of the more curious unexplained phenomena of our age is the continuous sightings of unidentified flying objects. The writer points out that unidentified flying objects (UFOs) have been sighted since ancient times and are still sighted each day. Some believe that the UFO phenomenon has something to do with everything from the pyramids to the beginning of life on this planet. Others insist that the entire idea is ludicrous and every sighting can be explained as either a hoax or as a result of "natural" causes. The writer discusses what actually classifies as a UFO and notes that one way of looking at this is to classify UFOs as anything that takes flight that is unidentifiable at the time. The writer maintains that the problem remains that numerous sightings do not fall into these categories and remain in the realm of the unexplained.
From the Paper
"Like many in the private sector, the government sightings are far from all being the same. On February 15th, 1965, a United States Air Force captain stared upward into the sky and, to his amazement, saw three enormous, oval-shaped objects. In 1953, while running the initial tests on a new tracking device, US Air Force operators were astonished to pick up a gigantic object orbiting near the equator. Some type of huge, unknown object was circling the Earth some six hundred miles out. Another, this sighting on May 5th, 1954, depicts a military that is not sure what they are dealing with ..."

Gamma-Ray Bursts, 2006.
This paper defines and analyses gamma-ray bursts.
1,316 words (approx. 5.3 pages), 13 sources, MLA, $ 44.95

Click here to show/hide summary
Abstract
In this article, the writer notes that about once a day, somewhere in the universe a burst of gamma rays appears as if out of nowhere. It lasts a very short time, no more than a few seconds, and then disappears. The writer points out that during the event, the level of radiation from the gamma-ray bursts is so high that it overwhelms any other gamma rays coming from other cosmic sources. It has also been observed that most gamma-ray bursts have an afterglow in the x-ray, and sometimes even optical, wavelengths ranges. The writer maintains that the research into gamma-ray bursts will continue until their nature is finally understood. The writer concludes that while this research goes on, the accumulated information and the intermediate hypotheses are already helping astronomers and cosmologists to better understand the universe, particularly the time when it was just beginning to form.

From the Paper
"Despite the inconsistent nature of these bursts, some patterns have been identified. One prominent distinction is between long and short bursts, those over 2 seconds and those less than that. Analysis of almost 2,000 gamma-ray bursts recorded by the BATSE device on the Compton Gamma-Ray Observatory between 1991 and 2000 showed that each falls into one of two groups: the short bursts have closely-spaced high-energy photons; the long bursts' photons appear to have lower energy and are more widely spaced.
"Another pattern that was discovered is related to the degrees of brightening and fading that the bursts exhibit over time in various channels of the measured energy spectra over the life of the burst. This analysis showed that different bursts release their gamma rays at different rates in different energy spectra When plotted, these variations manifested themselves as 5 distinct patterns: flat, crescent (or double-crescent), loop, lobe and island."
