Ellipse

a commentary on "The Conics of Apollonius", which included Ptolemy's numerous observations of the stars. This commentary also included dividing cones into different parts by a plane, which led to developing the concepts of parabola, hyperbola and ellipse. She is known for writing "The Astronomical Canon". Hypatia worked with her father on commentary of Book III of the Almagest as a note of her father (Theon) says. Most of her writings were meant to be used as text books to help her students with…

Eliana Dockterman is a published writer for Time Inc. whose almost indifferent tone is used throughout the essay in the hopes of settling the argument over technology's role in children's lives and development. This article comes at a time where parents are fearful of technology's role and influence on their children, and Dockterman clearly wants to encourage parents to monitor the use of technology, but not eliminate it. Dockterman's indifference is seen by the equal usage of credible evidence…

Carlie Zeisler Mrs. Stetson Scientific Revolution Paper Johannes Kepler “The path of a planet around the sun is an ellipse, with the Sun as the focal point,” -Kepler's first law of planetary motion. The Scientific Revolution was the beginning of the scientific discoveries that have formed modern science. This period started during the end of the Renaissance and continued throughout the 18 century. Johannes Kepler was a major figure in this period, including the observations mentioned in his…

“Sexual, racial, gender violence and other forms of discrimination and violence in a culture cannot be eliminated without changing culture.”(Charlotte Bunch) Plath and Hughes faced massive discrimination throughout their lives, and change was a great necessity. Plath and Hughes insist the inevitability of adolescent rebellion when confronted with discrimination; through punctuation and tone. Plath and Hughes both employ punctuation demonstrating the inevitability of rebellion in adolescents…

Hitomi paper or Belgian linen using ink, charcoal or even lithographic crayons to make technical drawings, then proceeds to the construction of a small lead model from flat plates –lead as it is very malleable and easy to rework, except in the torqued ellipses where he began with wooden models. He then goes on to consults a structural engineer who advices on how the work should be displayed giving consideration to its stability and balance. Then finally he heads to the site. His drawings are on…

There have been many prehistoric structures found by archeologists all over the world, one of them being the megalithic temples of Malta. Archeologists have dated the temples from 4000- 2500 BC, making it older than the pyramids and Stonehenge. The temples were made out of stone and consisted of an incomplete dome and horizontal arch and post and animal hide coverings. Most of the temples had a basic floor plan of a variable number of hemispheric chambers branching off from a narrow entrance…

example, Billy is describing what he sees as if it was a monochrome photography, in which there is light and “the color grey with remnants of brown” (13). As a camera would, he is scanning “the thirty or so grey cans in one corner of the room, their ellipses, from where [he] sat, setting up patterns in the dark” (13). The photography’s metaphor is seen in Billy’s visual impressions. He records what he sees as a camera would. For example, he “take[s] in all the angles of the room” (18). His…

We later learned that we can never be certain of where a particular electron is in the atom. We also cannot perfectly predict its path as a neat ellipse. In fact, we can only “guess” where they are located! “Guess” may not be the best term to use though, because the probability clouds are calculated with a complex formula with 4 variables. I won’t bore you with the math relating to it, but I will…

not the distance from the sun. The Earth rotates about 23.4 degrees. Because of this, in the summer the northern hemisphere is closer to the sun, not the Earth itself. The Earth is closer to the Sun during certain parts of the year, because if the ellipse orbit.…

Gravitation - Movement, or a tendency to move, towards a centre of gravity, as in the falling of bodies to the earth. (Oxford Dictionary) Introduction : For centuries, mankind has always been fascinated by the celestial bodies. The motion of the stars and planets were at once a symbol of the divine order of the universe and a profound challenge for human understanding. For the ancient Greeks the separation between the terrestrial and celestial realms was absolute--the downward motion of…
