There are many reasons that we need bridges in every day of our life, from sufficient means to pass over a roadway, waterway, railway, or other structure. You don’t even think about them because it takes no effort to get over them and they are just there for your use. So if you don’t think of them for everyday use I highly doubt that you […]
A Change of Heart Abstract The essential part of the circulatory system is the heart. In other words, any organism cannot live without this organ properly functioning. The duties and mechanisms of these functions must be performed correctly or else there could be potential serious consequences to the rest of the body. When the human heart has failing left and right ventricles, […]

Do the Laws of Physics Lie? Cartwright (1983) claims that the laws of Physics lie. There is causal power of things and specific interpretation of objects, which make the author reconsider the basic concepts of physics. First, the core idea of Cartwright is to underline the main goal of physics or the description of things happening around. Physicists accumulate some data, process them and summarize […]
Venturi & Orifice Meter INTRODUCTION As we learned in the Impact Jet lab, the speed of a moving jet of water is proportional to the water’s velocity. This is evident in a turbine flow meter, where the impact force of the water on the blades sets the rotor in motion. Once there is a steady rotational speed, we can say the speed is proportional to […]
Chapter # 02 Synthesis Techniques Introduction The different synthesis techniques for fabrication of nanofibers and nanoparticles will be discussed briefly in this chapter. The selected techniques and the experimental procedure for the synthesis of the nanoparticles and composite nanofibers will be discussed in detail. Synthesis Techniques for Nanoparticles Synthesis method being used for the preparation of nanomaterials is one of the most important factors that […]
The atomic theory is developed since 2000 years ago the Greek philosopher Democritus proposed that there was a limit to how small one could be divide matter, this smallest matter indivisible particle was called “atom”. However this atomic theory of Democritus was criticized by Aristotle who proposed a model based on four basic “elements” of earth, air, fire and water. Aristotle’s view held for the […]
The Motion of a Mass Spring System The example of a mass attached to the end of a spring is a powerful tool in physics due to the fact that it is analogous to many physical phenomena. To be able to use this example to elegantly describe other more complex systems it is crucial to first fully understand how this simple system works itself. The […]
Trusha Patel Isaac Newton by James Gleick Opinion Isaac Newton was the most famous scientist of his generation and one of the most recognizable physicists of all time. He accomplished amazing feats; he “pushed open a door that led to a new universe” (8). Some of his major achievements include the application of the law of gravity to the motion of planets, the path […]
