Nanotechnology Essay for Physical Science

...Nanotechnology Nanotechnology is defined as the understanding and control of matter at a very small scale which is called nanoscale. This type of science involves all different aspects like measuring, imaging, modeling and manipulation of matter at the nanoscale length. A Nano is so small that it is one billionth of a meter. In one inch there are 25,400,000 nanometers. The thickness of a sheet of paper is around 100,000 nanometers thick. As you can see, these are very tiny. This became popular in the 1980s by a man name K.Eric Drexler; that wanted to build machines from the nanometer. The Feynman theory was not to change the laws of physics but to enhance the possibility of maneuvering things atom by atom. Some new research in nanotechnology are developing nano-structures that will be able to tell the diseased cells from the healthy ones and then deliver the needed drugs directly to the cancerous tumors with no harm the healthy cells or to any other organs. Solar panels are another, because when using nanotechnology they are far more efficient than using standard designs that are now being use to convert sunlight to electricity. In return, solar power panels would be much more affordable. Researchers have also discovered that really small specks of rust can help remove arsenic from our drinking water. Imagine a fabric that is woven from tiny wires and that will absorb 20 times its weight in oil. A nano-fabric is being research and may be available for use in the near......

Biomedical applications and health technology help users at all of our facilities do their job and perform more efficiently. The focus of this paper will help look at the progression of biomedicine with technology and how health information technology is becoming a new technology in the sight of health care. I will follow the plan of introducing biomedicine then follow up with health information technology as a new technology research. I will also talk about the advancements that have come about as a result of new technologies. Biomedicine is described as “The application of the principles of the natural sciences, especially biology and physiology, to clinical medicine.”(Biomedicine) Biomedical applications are applications that service the need for biomedicine. Examples can be seen in software where the applications help physicians do their job more efficiently. There are EKG machines, devices that monitor glucose as well as other medical functions of the body. The biomedical studies themselves have shown the improvement in technology and what we can see in cell structures. For example some studies have shown that stem cells found in breast milk can turn into several different cell types, like bone, brain, live and pancreatic cells.(Stem Cells from Breast Milk) It can show as a new......

...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. Allen J.,Boyd P. (1997,April 15) The limitation of parallax is that it just gives distances to stars tp up to a few thousand light Years and beyond......

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). Objects in space aren’t the only challenges scientists face when trying to obtain......

...  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. In the case of solids, which have a definite shape and volume, the molecules vibrate “in a fixed equilibrium position with strong cohesive forces” (Tillery, B., Enger, E.,......

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. Purists in every sport would signify that paragliders have highly superior range and lift, but that parachutes are......

Lab Research Report 1: Procedures in the Physical Sciences

...Lab Research Report 1: Procedures in the Physical Sciences Rhoda H. Jefferson Professor Cassie Prisco Introduction to Physical Science November 2, 2013 The specific challenges to making direct measurements in the fields of astronomy, chemistry, physics, or earth science are measuring global warming and climate changes, measuring how the earth rotates on its axis, and measuring the distance from the earth to the stars. Scientist have had these issues for a number of years but overcome using indirect forms to measure these challenges. For global warming, scientist used a 350-year record of precipitation in California determined by using 52 tree ring chronologies as proxies for precipitation. (www.geosociety.org/gsatoday/archive/11/12/pdf/i1052-5173-11-12-41.pdf) This method was used to determine average annual precipitation, which showed extended dry periods. These methods were not 100% because there were no baselines to compare. In this day and time to obtain a temperature that represents a large area, it requires measurements of multiple locations. Measurements are taken by thermometers, and averaged together, this can aide in determining regional trends. (http://www.thenewatlantis.com/publications/taking-the-earths-temperature) Another challenge that scientist come up against is measuring how the earth rotates on its axis. When the earth rotates on its axis, it fluctuates in relation to space. This is caused by the gravity from the sun and the......

...LRR#1 Bryan Smith Lab Research Report # 1 Strayer University SCI 110.109GA063-1142-001 Introduction to Physical Science Professor Larry Smith January 27, 2014 The world has always been amazed with astronomy which is the study of earth, planets, space, and the universe as a whole. This is one of the oldest practice since the beginning of time. Many civilizations have studied this for years. This was before anyone came up with the idea to build a ship to visit other planets. People have always been amazed by the unknown, and this is why we still have people going to outer space to discover new things. The use of the research for studying outer space is known as Astronomy. According to the web dictionary Astronomy is the scientific study of the matter in outer space, especially the positions, dimensions, distribution, energy, and evolution of celestial bodies and phenomena (http://www.thefreedictionary.com). Early scientist could not just look up in the sky to measure how far away a star actually is and to see what else is up in space. There is other techniques and equipment is needed. Early scientist use a technique called triangulation. This was done by looking at a star and record its location. Then six months later scientist would look at the star again and measure the distance and record any changes (How are astronomers, 2000).

Review Bent Flyvbjerg Making Social Science Matter

...Student: Natalie Hallinan Review of Bent Flyvbjerg’s book Making Social Science Matter: Why social Inquiry fails and how it can succeed again Advanced Organisation and management Theorising 1 The “science wars” of the mid to late 1990s appears to have been an ideological contest of wills between the natural and social sciences. The natural science ‘camp’ included such heavyweights as a Nobel prize-winning physicist and a Harvard biologist and geneticist. The latter, R.C. Lewontin in the New York Review of Books harshly chided the U.S. National Opinion Research Center sexual practices study authors. “It is frightening to think that social science is in the hands of professionals who are … deaf to human nuance”. He concluded that social scientists’ propensity to impersonate natural science “can only engender the scorn of natural scientists”(p2). Given the apparent harshness of this critique, it may seem surprising to find a social scientist seeming to agree with the positioning of the natural scientists. This is precisely what Bent Flyvbjerg’s appears to do, albeit with a different premise, in the first chapter of his book ‘Making Social Science Matter: How Social Inquiry Fails and How it can Succeed Again’. Flyvbjerg articulates the case for a revision of the theoretical underpinnings of social science and the development of a new version of an old concept through a return to and reinterpretation of the Aristotelian concept of ‘phronesis’, or practical wisdom.......

Intro to Physical Science

...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. You can get eyewitness testimony from the loss prevention personnel and or others that witnessed the suspect......

Physical Science

...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......
