I have learned from my twenty years of service in the U.S. Air Force, significant background knowledge of the history of the space shuttle. In September 1969, two months after the first manned lunar landing, a Space Task Group appointed by the President of the United States to study the future course of U.S. space research and exploration made the recommendation that "…the United States accept the basic goal of a balanced manned and unmanned space program. To achieve this goal, the United States should …develop new systems of technology for space operation…through a program directed initially toward development of a new space transportation capability…" According to Cox (1962), many responsible observers felt that we were devoting too many of our resources to increasing an already affluent volume of private consumption and too little for public services, including space-flight programs. In early 1970, NASA initiated extensive engineering, design, and cost studies of a space shuttle. These studies covered a wide variety of concepts ranging from a fully reusable manned booster and orbiter to dual strap-on solid propellant rocket motors and an expendable liquid propellant tank. Each concept evaluated development risks and costs in relation to the suitability and the overall economics of the entire system. On January 5, 1972, President Richard M. Nixon announced that NASA would proceed with the development of a reusable low cost space shuttle system. NASA and its aerospace industry contractors continued engineering studies through January and February of 1972; finally on March 15, 1972, NASA announced that the shuttle would use two solid propellant rocket motors. The decision was based on information developed by studies that showed that the solid rocket system offered lower development cost and lower technical risk. On September 17, 1976, the first orbiter spacecraft,...

...Assignment 1 Energy can be converted from one form into another in three basic ways know as the action of force. The first one is gravitational forces which is when gravity accelerates a falling object, its converts its potential energy to kinetic energy. Likewise, when an object is lifted the gravitational field stores the energy exerted by the lifter as potential energy in the earth-object system. The second one is electric and magnetic force fields which is charged particles, upon which electrical fields exert forces, possess potential energy in the presence of an electric field in a way similar to that of an object in a gravitational field. These force fields can accelerate particles, converting a particle's potential energy into kinetic energy. Particles can interact via the electric and magnetic fields they create, transferring energy between them, and in the case of an electrical current in a conductor, cause molecules to vibrate, for example converting electrical potential energy into heat. This leads to the third action of force which is frictional forces(www.powerincooperation.com)This is defined as macroscopic energy of an object, that is, the potential and kinetic energy associated with the position, orientation, or motion of the entire object, not counting the thermal or heat energy of the system, can be converted into heat, whenever the object slides against another object. The sliding causes the molecules on the surfaces of contact to interact via......

...I enjoyed everything about the criminal investigation but the three things that I enjoyed the most was looking at the stages of human decomposition it was an exciting thing to see how in different climates and areas affect the way the body decomposes over time. Also, the different ways it dries out of if worms start to form how big are the worms or how old all this can lead u to figuring out how much time a body is sitting on that place. Another way of finding how old the body is by looking at the skin texture if it was submerged under water for a while the skin is almost white soft and swelled. If the body was in the sun for a while the skin is more dry kind of mummy like. The second thing I enjoyed was the mock homicide crime scene because I learned a lot from it. I learned how to mark evidence what sorts of evidence appear in a crime scene. I got to see kind how a crime scene looks with fake dummy and evidence marks all over the room. There was blood spatter on the room floor and on the victims. This helps to see how the blood was laying and determine the way they killed the victim. Also there was a lot of fingerprint evidence and DNA we could use to see how many people were involved n who they were. Lastly the third part of this investigation was the Autopsy videos we watched in class. It was amazing to see how the dead bodies carefully opened up and analyzed to see what the cause of death was. The most interesting part of it was how they get to the brain the carefully......

...Lab Research Report 1: Procedures in the Physical Sciences Robert Hugee Professor Brian McCann SCI110024VA016-1134-001: Introduction To Physical Science April 25, 2013 One of the underlying challenges in astronomy measurement is the determination of precise distances. Without a knowledge of its distance, the size of an observed object in space would remain nothing more than an angular diameter, and the brightness of a star could not be converted into its true radiated power, or luminosity .astronomy. (2013).  Direct measurement of the wavefunction had also long been deemed impossible because of the key tenet of the uncertainty principle. University of Rochester (2013, March 3). Getting around the uncertainty principle: Physicists make first direct measurements of polarization states of light. ScienceDaily. Large-scale surveying & mapping problems are also key challenges in making direct Measurements in astronomy. Pogge R.(2006) One of the indirect forms that the scientists have used is to resort to GEOMETRY to find the Distance. Parallax is one of the indirect methods where astronomers can measure the position of a nearby star very carefully with respect to more distant stars behind it, then measuring those distances again six months later when the Earth is on the opposite side of its orbit.

Procedures in the Physical Science

...Procedures in the Physical Science Erica Taylor Introduction to Physical Science April 25, 2013 Procedures in the Physical Science Science is defined as the systematic knowledge of the physical or material world gained through observation and experimentation (science, n.d.). Science is an ongoing quest for knowledge and understanding of not only the world itself, but the universe as well. In order to accomplish this quest, scientists use many tools to measure and analyze a variety of elements and phenomena in order to have a clear understanding of why things are the way they are. There are times however when direct measurement of something is not an option requiring scientists to find alternate solutions. Astronomy is the scientific study of the universe and what it is comprised of such as stars and planets. A scientist cannot simply use a ruler to measure how far away a star actually is and therefore indirect measurement techniques are needed. One such technique is the parallax method which involves triangulation. By looking at a star and record its location and then looking at it again six months later, astronomers can measure the distance of the angle of viewing. Combining this information with the orbital diameter of Earth to the sun and a little bit of geometry, astronomers can see that the different angles produce different distances (How are astronomers, 2000)....

...Daniel Calderon SCI 110 Intro to Physical Science Strayer University Dr. Jack Crawford 03/09/2015 Scientific Method The scientific method is a way to ask and answer scientific questions by making observations and doing experiments. The steps of the scientific method are to: 1. Ask a question 2. Do background research 3.Construct a hypothesis. 4.Test your hypothesis by doing an experiment 5. Analyze your data and draw a conclusion. It is important for your experiment to be a fair test. A "fair test" occurs when you change only one factor (variable) and keep all other conditions the same. While scientists study how nature works, engineers create new things, such as products, websites, environments, and experiences. Hypothesis For my job as a police officer we do follow a similar course of action with the scientific method. I will break it down following the similar steps we use. In my example I will process a simple shoplifting to make it easier to understand. The first step would be to ask the question did the suspect shoplift. The second step do background research would consist of reviewing the video of the crime and determine if the suspect meet the requirements for the shoplifting. Did the suspect take an item, conceal it and then not render payment for the item? If the suspect did all three on video then you can use that as evidence....

Physical Science of Sky Diving

...The Physical Science of Skydiving Vanessa Laine Gabriel Dr. Burkeen Westwood College The Physical Science of Skydiving Introduction Skydiving which is also known as parachuting, is the action and adventurous sport in which a volunteer exit takes place from an aircraft for returning back to earth with gravity aid with the help of parachute for slowing down throughout the last of the safe descent of earth. This action may or may not comprise of a specific amount of free fall, but a moment in which the parachute has not been set out and the body accelerates gradually to terminal velocity. In this paper, a discussion will be conducted on the physical science of the skydiving. Skydiving is performed as a competitive sport and a recreational activity, as well as it fulfill the deployment of the Airborne forces’ military personnel and rarely forest firefighters. When a parachute opens as, that will be completely inflated by 2,600 feet or 800 meters, (BBC News, 2009) and then the skydiver can control the speed and direction with toggles on the steering lines’ ends that are linked to the parachute’s trailing edges, and can intend for a safe landing and eventually arrive to a moderately tender stop. All the contemporary sport parachutes have ‘ram-air’ wings that are self-inflating and assist in controlling the direction and speed as per the linked paragliders....

...Introduction to Physical Science – SCI110 Assignment #2 Week 4 Melissa Garrett Assignment #2: Paper Due Week Four: In a documented essay of 900 - 1200 words please address the following issues, in your own words:   * How does the study of heat relate to the kinetic theory of matter? * What is heat? * What is temperature? * What is the relationship between heat and temperature?  * How are they different? * What are the various properties of a substance that determine its heat capacity? * What are the various sources of heat? Conclusions about the structure of matter have been developed by physicists and chemists over the past 150 years. To understand it further let us look at the structure and the processes that occur to determine the state in which it exits. Matter typically exists in 3 common states or phases: solids, liquids, and gases. It is made up of molecules. “A molecule is the smallest particle of a compound or a gaseous element that can exist and still retain the characteristic properties of that substance” (Tillery, B., Enger, E., Ross, F., Integrated Science 2009 Custom Edition, p.98). According to the Kinetic theory of matter, these molecules are in constant, random motion. Through the force of cohesion, molecules interact and attract each other....

Physical Science 2 Hesc Research

...I think that the human embryonic stem cell (hESC) research should be continued since if this research is successful, it can be beneficial for all human beings and encourage further development. Because hESC is pluripotent, it can transform to any other types of cell. Thus, it can be used to cure many diseases that are incurable, such as type-1 diabetes and genetic disorders. Many people will gain from the hESC research. Moreover, the research also encourages many further developments. For instance, Shinya Yamanaka has successfully transformed human skin cells into induced pluripotent (iPS) cells, which function exactly like human embryonic stem cells. Thus, I think the hESC research should be continued. I think that scientists should not use discarded embryos from fertility clinics to conduct human embryonic stem cell research since this source of embryos addresses the concerns of those who do not want to see embryos destroyed for research purposes. Scientists can use induced pluripotent stem cells instead. In this way, they can avoid many controversies of using discarded embryos from fertility clinics, and the iPS cells act exactly like the hESC. Although the embryonic cells are going to be destroyed, many people still think that destroying embryos for research is violating sanctity of life. Therefore, using iPS cells can solve the ethical problems that bring from using hESC for research, and the iPS cells are easier...
