Essays on Aberration

Gloria E. Anzaldua, in “How to Tame a Wild Tongue,” uses language and the way it is used to forge and assert identity as a way to discuss the racial tensions that come from the strict binaries expected by society. While this extends chiefly to issues of white/non-white, particularly through the regulation hegemonic American society places on the languages spoken within it, there are issues of rich/poor, male/female, and others that are defined and asserted through language. In this respect, Anzaldua argues that ‘linguistic terrorism’ is often used by those in power to limit the speech and power of ...

The social construction of gender is a prevailing concern among many social theorists and modern culture, particularly as society becomes more aware of the often arbitrary delineations between what is ‘male’ or ‘female’ about things like behavior, dress and attitude. Aaron Devor’s “Gender Role Behaviors and Attitudes” explicitly explores these issues of the cultural construct of gender, particularly the ways in which male and female behaviors are defined and categorized. This becomes especially important in the context of Mariah Burton Nelson’s “I Won, I’m Sorry,” which looks at these stratified gender behaviors in the context of ...

At times, one can see many animals out in the night with their eyes glowing green or yellow-green in color. In all kinds of light and media such as nature films, photographs, flashlights and even car headlights, the greenish glow in the eyes of many animals is clearly visible. Human eyes, on the other hand, give off a red glow when exposed to the flash of a camera. The greenish glow in the eyes of many animals such as cats, dogs, deer, cattle and horses is mainly because of a special kind of reflective surface that lies behind the ...

Apparatus Light source (incandescent bulb); Rail; Red filter; Blue filter; Screen (image); Reference grid (object); Stands; Light blockers. Introduction Chromatic aberration results from the condition of state in which a lens fails to focus all colors passing through it at the same focal point. The failure occurs when the lens has got more than one refractive indices meaning that there also exists more than one focal point. Reason being that the focal point of a lens depends on its refractive index. There exist two types of chromatic aberrations one being axial and the lateral. The axial type of aberration ...

Lab report:

Introduction For this experiment, the focal length is taken to be the image distance that is in correspondent to an infinite object distance; in which case, the incoming light rays are taken to be parallel. By performing this experiment, it presents a platform for determining the focal length by using the focal length equation: 1f= 1p+1q Whereby, f is the focal length, q is the object distance and p is the image distance. To get these two variables (object distance and image distance) involves focusing the image of an object under illumination on a screen and the measuring ...

Introduction

The passage from the Republic by Plato is prone to different interpretations. To gain full comprehension of the passage the reader is obliged to delve deep into the platonic debate between Socrates and Glaucon. The trajectory of the argument according to Plato, was that democracies are governments ran by fools. The principal argument in the discussion was that democracies elect courses of action without a coherent understanding of the matter they are handling. The overriding argument was that only those who are fully experienced in statecraft should be allowed to rule. ‘Socrates argued that the cobbler and the medical doctor ...

While on his way to Hiroshima, it was around 7:30 a.m. when Captain William Parsons inserted the detonator along with the explosive charge into the bomb. It was around 8:16 a.m. (Japanese time) when the bomb exploded in Hiroshima over Dr. Shima’s Clinic. The glowing fireball had a temperature of about 50,000 degrees. Soon after this attack, another major city of Japan was attacked. It was basically the idea of General Leslie Groves, General Farrel and Admiral Purnell to launch two atomic bombs on Japan; the first bomb would demonstrate power and the second would tell the Japanese ...

Discuss Chromatic aberration in a lens.

- Introduction Chromatic Aberration is an optical issue which occurs when a lens either focuses wavelengths at different positions in the focal plane or cannot converge all wavelengths of color to the same focal plane. It is caused by dispersions of the lens, with different wavelengths of light passing through the lens at different speed. Consequently, the image appears blurred or may have noticeable colored edges (Smith, 20). - Main Body A perfect lens would direct all light wavelengths into one focal point. In real situations, each wavelength has different refractive index in lenses, hence resulting into ...

Introduction

The microscope is derived from two Greek words, mikros and skopeo. Mikros means small while skopeo means “look at.” Thus, the two words form the word mikroskopeo that refers to looking or observing small objects. Since the beginning of scientific developments, there has been an interest to look at the smaller details of the world around us. Biologists have taken the lead in the quest to uncover such small details through their desire to examine cells, viruses, bacteria, and colloidal particles. Material scientists have wanted to observe the limitations and inhomogeneities in metals, ceramics, and crystals. Geologists have also ...

Every organization is developed through formulation of a plan. The plan can be either arbitrarily present in the mind of the founder or well documented by a panel of experts after due deliberations. The size and operational level of the organization determine the extent to which expertise are applied for the formulation of the organizational plan. An organizational plan forms the basis of an organization through defining its mission, vision, values, structure, size, type, processes, resources and strategies etc. The organizational plan for a fictional company named zRock Inc. is developed in this paper that requires detailed considerations to be undertaken due ...

Electron microscopes refer to those microscopes that make use of an electron beam to light a specimen producing a magnified image. These microscopes are used to study structures that are either invisible through naked eyes or those that are too small to be clearly seen using a light microscope. The two major types of electron microscope are Transmission Electron Microscopy or TEM and Scanning Electron Microscopy or SEM (Mooney, 1996). Transmission Electron Microscopy employs a high voltage electron beam in order to create an image (NE, 2013). The TEM is made up of various components including electromagnetic lens system, electron source, sample ...

1. a) Find the U.S. inflation rates between 2002 and 2007 from the IMF website and calculate the Purchasing Power Parity (PPP) exchange rates for Countries A, B, C and D in the case study. (The inflation rate in each country in the case can be calculated from the Consumer Price Index. For Example: inflation rate for country A=14.7%= 132.9 – 115.9 /115.9 [20 marks] b) Did Purchasing Power Parity theory hold in these countries? Which currencies are over- or under-valued against the US dollar? [4 marks] c) Find the U.S. dollar lending rates (prime rate) between ...
