    than a degree. Arcminutes are one sixtieth of a degree and arcseconds are one sixtieth of an arminute. One example of the infinitesimal size of an arcsecond could be the width of a dime from a point of view two kilometers away (“Cool Cosmos”). These units of measurement are used in the parallax formula, or the formula used to calculate distance when given an object’s parallax measurement. The distance given from the parallax formula is in parsecs, which are 3.26 light years or 3.18x10^13 kilometers

    was able to determine approximate distances between the planets through trigonometry. The distances were all found relative to the distance between the Earth and the Sun, the astronomical unit. Kepler refined these measurements to take into account the elliptical orbits. However, they did not know how large an astronomical unit was. To establish an absolute distance scale, the actual distance to one of the planets had to be measured. Distances to Venus and Mars were measured from the parallax effect

  • Challenges Of Interstellar Space Travel

    691 Words  | 2 Pages

    Introduction The idea of interstellar space travel has been discussed for many years between many scientists and engineers since 1950s (Adelman, 180). It has not only been discussed but also demonstrated in science fiction literature. By getting the knowledge of interstellar travel, people wonder when will we be able to travel between stars and if it is even possible to reach another star other than the sun. However, others wonder “what is the point of spending so much money on something that it

  • Image Analysis Program

    Purpose: to become familiar with the image analysis program and to develop an understanding to the size and age of planetary nebulae Procedure The first part of the experiment involved using a picture of a church and back round to understand different pixels, ADU, zoom, and how to get the (x,y) coordinates. We then took this brief understanding of pictures and applied it to the stars. We loaded a picture of nebulae m42. After this we needed to calculate the average number of stars or solar masses

  • Corvus Research Paper

    876 Words  | 2 Pages

    The constellation I have chosen is Corvus. Meaning crow or raven in Latin, Corvus has been a symbol of deviance and stealth for a long time. Corvus is part of the Hercules constellation. He is also typically depicted with two other constellations, Crater and Hydrus, as this is whom he shares the sky and story with. My choice in this particular constellation is to ease my curiosity as to why the raven or crow is what it is and why, despite being two different birds, they are depicted as the same.

    Through the material taught in creation studies, I have expanded my biblical worldview and strengthened my trust in the redeeming power of God as the perfect creator. As I conducted my interviews, I realized many people are uninformed on the biblical creation accounts and there do not understand they are compromising with evolution. There were four main question that this course answered –How long were the days in Genesis 1? How old is the earth and life? Does man and apes share a common ancestor

  • Using Computers to Model the Physics of an Asteroid Crash

    1813 Words  | 4 Pages

    Includes Source Code Computers in Physics Abstract This project is an experiment that sets up the earth's original velocities in the x and y direction and changing them with the velocities/momentum of a meteor. It attempts to simply model a meteorite or asteroid impact upon the earth and the subsequent change to the earth's orbit in terms of distance and speed in relation to the sun. Given the meteor's mass, velocity, angle, and the earth's coordinate point at the point of impact, the

  • Stars

    STARS The magnitude scale was invented by an ancient Greek astronomer named Hipparchus in about 150 BC He ranked the stars he could see in terms of their brightness, with 1 representing the brightest down to 6 representing the faintest. Modern astronomy has extended this system to stars brighter than Hipparchus' 1st magnitude stars and ones much, much fainter than 6. As it turns out, the eye senses brightness logarithmically, so each increase in 5 magnitudes corresponds to a decrease in brightness

    “Its SilverBlade.” “SilverBlade?” asked Lieutenant Mesa. “SilverBlade was one of the TDF Veterans who joined to help us when UF was first formed. Once we got going though he effectively disappeared, I wasn’t even aware that he had UF Intelligence Clearance.” “I was not aware that he was either, Commander; however, the code does match the one he used back when he was with us.” “Sounds to me like he and some of the UF Forces of Luna may have joined forces. That could explain the frequency he is

    actually consists of a pair of nearly identical stars each some 55,000 times more luminous than the Sun separated (from our perspective) by only 2.5 astronomical units. The temperature and luminosity show each to contain 15 solar masses. Spectra suggest an orbital period of not quite a year, this and the masses rendering them an actual 3 astronomical units apart. Twin Hadar also has a fourth magnitude sibling 1.3 seconds of arc away that, because of the brightness difference, is difficult to see and

    A Brief History of Clocks: From Thales to Ptolemy The clock is one of the most influential discoveries in the history of western science. The division of time into regular, predictable units is fundamental to the operation of society. Even in ancient times, humanity recognized the necessity of an orderly system of chronology. Hesiod, writing in the 8th century BC., used celestial bodies to indicate agricultural cycles: "When the Pleiads, Atlas' daughters, start to rise begin your harvest; plough

    An Analysis of Donne’s A Valediction: of Weeping William Empson begins his critical essay on John Donne's "A Valediction: of Weeping" with the statement below.  Empson here plays the provocateur for the critic who wishes to disagree with the notion that Donne's intentions were perhaps less than the sincere valediction of a weeping man.    Indeed, "A Valediction" concerns a parting; Donne is going to sea and is leaving his nameless, loved other in England, and the "Valediction" is his emotive

    “Anika! Can you come down here dear?” Mrs. Carly called me from downstairs. I grabbed my stuffed bear, Cuddles, and walked downstairs. I found Mrs. Carly sitting next to a tall woman on the couch in the living room. “Is it time to go to lunch?” I asked. Mrs. Carly smiled and shook her head. “No dear, but we’ll leave soon. I promise. Anyways, this is Amber Canefield. She’s probably going to adopt you.” In case you couldn’t tell, this isn’t like a house and obviously, Mrs. Carly isn’t my mom. I

    down in a body tube that surrounds them. For many years, closed MRI units have been the standard in helping physicians make a diagnosis. These closed MRI units featured a long tube that the patient would be placed inside during their procedure. This was often uncomfortable for many patients due to the "closed in" feeling and was especially stressful for patients who suffer from claustrophobia. The newest generation of MRI units is now open on all four sides which completely alleviates the "closed

    category the structure turns out to be a model on its own. The self-application leads on the level of the axioms to the boolean lattice of all substructures and on the level of the terms of axioms to semantical boolean lattices, which may seen as basic units for the whole language. Thus the understanding of the structure of ‘wholeness’ takes for granted that there is a pre-understanding of the very same. Furthermore, there is another kind of circular understanding on the level of the atoms of the structure
