How to Collimate Your Newtonian Reflector by Vincent S. Foster Before you can observe with a Newtonian reflector telescope, you need to align or collimate its optical parts. The goal of collimation is to insure that both the primary and secondary mirrors as well as the eyepiece are correctly lined up to give clear, sharp views. You might think that collimation begins with the primary mirror because it is the most important part of the optical system. Curiously enough, it does not. Collimation is
interferometer consists of two mutually perpendicular plane mirrors, one of which can move along an axis that is perpendicular to its plane. Bisecting the fixed mirror and the movable mirror is a beamsplitter, where a collimated beam of radiation which could be infrared light emitted by an external source (Globar, metal wire, Nernst bar ), can be partially reflected to the fixed mirror (at point F for the median ray) and partially transmitted to the movable mirror (at point M). When the beams
Ephesians 5:8-16 Ephesians 5: 8-16 is about how we are the light and the hope of the world. This passage tells of how we need to live with righteousness and truth. It explains of how we must not have anything to do with fruitless deeds, but instead we should expose them to the light. For this, in turn, will make the darkness visible and the light will wake up the disobedient. It also instructs us to live a wise life and to make the most out of every opportunity we have. This passage has great
Polarization Introduction: PART ONE: POLARIZATION Method 1: Two polarized disks were put into a grooved holder with their polarization axes lined up, and a bright red light emitting diode (LED) was placed on one side, and a light sensor was placed on the other side. Light intensity was measured as a function of the plastic rotating polarizer angle from 0 to 180 degrees. Science Workshop was used to measure the intensity for every 5-degree rotation (Fig 1). Method 2: The mineral calcite

every one he meets. Gunther uses light in various ways in his memoir. When Johnny is at home, with friends, or studying the light is always present. This symbolizes him getting to be him with out a single thought of the disease, in essence his happiness. When Johnny is getting worse, or more bad news is brought forward the room always seems dark or full of shadows. Even though it is dark there always seems to be a little light. For example a crack in the door with light beaming through, the moon hitting
HOW ARE TENSION AND SUSPENSE BUILT UP AND MAINTAINED IN AT LEAST TWO GOTHIC HORROR STORIES? The original use of the term `Gothic Horror' was applied to a group of novels, including Mary Shelley's `Frankenstein', written before 1914. These novels usually included some or all of the following characteristics, which seem demonstrative of the original use of the term `Gothic': An emphasis on portraying the terrifying, a common insistence on archaic settings, a prominent use of the supernatural

Reproductive Fantasy is Burning Of fire, what can be written that would not be better off singed, immolated, baked, or outright burnt? Flame of the match lights a watch. Dancing embers of destruction hide records, burn bodies and papers. Glistening radiance of torches light the way through the night of Victorian horror and fantasy. Fire is lively (it breathers, it takes in, it puts out, it moves, it grows, and it makes more) yet takes away life (defined by the same characteristics.) Everywhere
The Man In The Moon I lie on the grass, staring above me, my arms stretch high into the starlit sky, they warp and twist and elongate and they reach up and my hands grasp the moon and its mine and no-one else's and my fingers become a part of it and then I'm the moon, look at me I'm the Man in the Moon and I Can See All, I Can See You, and my arm stretches down and my giant finger uncurls and points and my voice deep and booming says ITS YOU and the person I'm pointing at looks straight up at me
Investigating the Speed of Water Waves Introduction In this experiment I will be investigating the wave speed, of waves on water in a tray, and how this speed is affected. Waves can be longitudinal, when the particles move in the same direction as the direction of the wave, or it can be transverse, when the particles move at 90o to the direction of the wave. Water waves are transverse waves even though transverse waves cannot travel through liquid. This is because the waves travel
The distinctive piece in each of of the three candlelight paintings is the light source. Wright places the light source of the entire room in the center of the painting, giving the rest of the room an almost creepy glowing effect. Since the light is placed in the center of the painting, all corners of the room seem to be lit, even though the top right corner shows a mere silhouette. The insufficient amount of light gives the viewer an idea of how dedicated the subjects were in order to be in the
by Samuel Beckett, light and its opposite, dark, are used to represent Krapp’s rejection of intellectual, physical, and emotional interactions for his transient comfort of the dark. He disregards these important aspects of life by using the dark as a place where he can confine his addictions, memories, and remorse. Krapp views the dark as a source of freedom and a place of work while light is synonymous of love and his previous chances of happiness. The contrast between light and dark demonstrates
contradicts the typical views of light and dark. While typically light is imagined to expose the truth and darkness to conceal it, Conrad creates a paradox in which darkness displays the truth and light blinds us from it. Initially, the story endorses the conventional views of Western society, exhibiting light as a positive and reassuring presence without truly comprehending the truth it reveals. Before Marlow begins his story, the sky around the boat he reclines on is full of light. “The sky, without a speck
Yet as we journey from the dark to the light in Aeschylus, we cannot leave the dark behind – the darkness breeds the light. ⎯ Robert Fagles and W. B. Stanford, “Introduction: The Serpent and the Eagle” It is without fail that throughout Aeschylus’ trilogy, The Oresteia, the presence of light and dark can be found in the characters, the plot and the themes. The trilogy follows the House of Atreus its emergence from darkness into the light. However, the light and darkness are often presented symbolically
The Symbolic Use of Light and Dark in James Baldwin's Sonny's Blues In James Baldwin's "Sonny's Blues" a pair of brothers try to make sense of the urban decay that surrounds and fills them. This quest to puzzle out the truth of the shadows within their hearts and on the streets takes on a great importance.

Molly Brang's Ten Principles My picture contrasts the dark, sharp, menacing objects with the light, calm, serenity of the hand. Using Molly Bang’s ten principles, I was able to depict this evil and suspenseful moment from the story, "Sleeping Beauty." Molly Bang’s ten principles teach us how to illustrate moments from stories or poems with abstract shapes and basic colors. By applying these principles, any emotion can be expressed. Maleficent was the most challenging object in the picture

lived at the difficult and perilous limits of the human condition. In “Macbeth” the first scene presents a meeting of three witches during stormy weather. Shakespeare shows disturbed, angry nature - thunder and lighting represent light - daytime and dark – night-time. Light is the metaphor for innocence, purity, truth, and goodness as opposed to dark - evil. It is also a suggestion that the innocent will suffer as well as the guilty. The fog and filthy air signify moral and spiritual obscurity and
Animality and Darkness in Othello An initial reading of Othello would suggest that animality and darkness are indeed in opposition to beauty and light. This view is affirmed by looking at the language and actions of Iago, 'Though I do hate him as I do hell-pains' in contrast to Desdemona, (or even the early Othello),'Not to pick bad from bad, but by bad mend.' Animality and darkness can be clearly seen in the character and more specifically the language of Iago. From the very opening of the
