Throughout the story “The Repairman‚” several scientific devices of varying accuracy are presented. The author describes and uses some that use plausible science‚ but the facts and possibilities of each are not important to the story as a whole. The varying devices are described just enough to propel interest in the story‚ but most of the actual scientific plausibility has to be inferred from context. In the story‚ hyperspace travel is presented in a way that explains itself to a degree‚ but in

Human Body System. I was interested in how each specific area plays a distinct role in the body and how certain body parts are interlinked with each other - a typical example of this being the skeletal system. When learning about radioactivity in physics I found it captivating how specific

Newton is without a doubt‚ a hero. He is a hero because of his scientific achievements and life events. He found a way to split white light and find its color contents‚ he discovered then extended his three laws of motion that frame the world of physics‚ and for crying out loud‚ the man invented calculus. Not just that‚ these examples aren’t even including all of his very many scientific achievements‚ inventions‚ or founds. For starters‚ Isaac Newton’s theory of “fluxions” or calculus‚ was a giant

Madeline Totten Dr. Su Phy 110 Lab 18 September 2013 Lab 2: Introduction to DataStudio Purpose: The purpose of this lab is to practice designing an experiment by choosing the variables‚ using DataStudio to collect the data from the experiment‚ and then taking our data and presenting it and our results in a report. Method: For this experiment‚ the goal was to use a simple pendulum (shown to the left) to measure the period of the motion. For task 1‚ we just became familiar with DataStudio

An inclined plane is a flat supporting surface tilted at an angle‚ with one end higher than the other‚ used as an aid for raising or lowering a load. Inclined planes are widely used to move heavy loads over vertical obstacles; examples vary from a ramp used to load goods into a truck‚ to a person walking up a pedestrian ramp‚ to an automobile or railroad train climbing a grade. Inclined planes are widely used in the form of loading ramps to load and unload goods on trucks‚ ships‚ and planes. Wheelchair

Sam Preusser Mr. Staude U.S. History 25 April 2013 Truman Doctrine VS. Marshall Plan The years after the war brought times of disagreement and argument. The United States worked at this time to contain and control the spread of communism. During the years of WWII and the Cold War this idea was prominent and an issue America thought must be solved. Their were two strong attempts to fight communism. These attempts were the Truman Doctrine and the Marshall Plan. These ideas go hand in hand making

Determining a Person’s Power through height/work Power is denoted by the formula‚ P = mgh/t. In lifting a bag‚ work is done. So in order to get power we recorded our weight‚ measured the weight of the bag‚ and the time it took to lift a bag. The experiment is done in two ways 1) with constant time and 2) with constant height. In this way‚ we can compare and know if there will be a difference in the amount of power exerted by a person if either time or height will be constant. The formulated

It wasn’t until the day that suited men from the Environmental Protection Agency came to his house‚ raiding his makeshift lab in the backyard‚ for his self-deemed project to gain national recognition and reveal exactly what his obsession turned into- a homemade nuclear reactor. Since the early age of four‚ David Hahn began

TOK Essay 4. “That which is accepted as knowledge today is sometimes discarded tomorrow.” Consider knowledge issues raised by this statement in two areas of knowledge. Knowledge is formed from different ways of knowing‚ with different language‚ perception‚ reason and emotion‚ a same issue can be interpreted differently by different person or group. From a personal level perspective‚ due to the difference in their background‚ culture and experience etc‚ a person’s knowledge is often different with
