During the fences harkness last week i learned many interesting things‚ not only about the book but also about my classmates and how they see the world. While some of my classmates would see a quote or theme of the book in a hopeful or positive way‚ others would see the same thing in a more pessimistic or negative light. A good example of this is when they discussed whether or not Troy was a tragic hero. While some of my classmates thought that he fit the definition of a tragic hero well‚ others

I absolutely love jumping on the trampoline but I never really thought there was any physics involved. I knew you had to use a force to jump up and gravity pulls you back down obviously. An American inventor named George Nissen first invented the trampoline in 1935. (Silvia) A trampoline is defined as an elastic disc of hard canvas held up by metal springs attached to a metal skeletal frame. Kinetic and Potential energy allow you to be able to jump on a trampoline. PE=mgh this equation helps you

Proof Fence" What comes to your mind when you here the words "stolen generation." Maybe you think of the Holocaust when the Jews were unwilling taken to concentration camp’s to suffer before their horrific death. Or you might think of the European settlers going to Africa to literally kidnap its people and bring them to the Americas for slave labor. Both are good assumptions but are far from what the "stolen generation" really is. Until watching the documentary "Rabbit Proof Fence" I would

Since the birth of Physical Review Letters fifty years ago‚ condensed matter physics has seen considerable growth‚ and both the journal and the field have flourished during this period. In this essay‚ I begin with some general comments about condensed matter physics and then give some personal views on the conceptual development of the field and list some highlights. The focus is mostly on theoretical developments. DOI: 10.1103/PhysRevLett.101.250001 PACS numbers: 01.30.−y The transistor

Edgar Xiong David Blackburn Period 3 Physics of Flight One may wonder‚ what is flight? Many just stare up into the blue skies above and assume. while others devote their lives to discovering and finding a passion in aviation. Flight can be simply characterized as the [powered] gliding of an object through the air‚ but the wonders of soaring through the air does not simply stop there‚ instead‚ flight is a whole myriad of forces acting on each other‚ as so found out by scientists decades

people fail to realize the importance of physics in athletics. People who are untrained in the scientific field may believe that an athlete’s performance level is solely based on their skill-set‚ such as strength and training. However‚ one’s ability to employ physics concepts is the true determinant for success. This is imperative to dancers; most movement and technique can be improved dramatically by following Newton’s laws accordingly. By utilizing key physics concepts‚ a dancer can improve by locating
