Understanding Eclipses Essay - 516 Words

Understanding Eclipses A scientific event which captures my interest and attention is an eclipse. In astronomy, an eclipse is a complete or partial obscuring of a celestial body by another. An eclipse occurs when three celestial objects become aligned. There are two distinctly different types of eclipse phenomena known to astronomers. In the first, the eclipsing body comes between an observer and the eclipsed object while the other celestial object appears to the observer totally or partially covered by the eclipsing object. An example of this is when eclipses of the Sun occur(This is known as a solar eclipse). A solar eclipse occurs when the Moon, revolving in its orbit around the Earth, moves across the disk of the Sun so†¦show more content†¦In rare instances, more may occur, as in 1935, when there were five solar eclipses. Eclipses of the second type affect only planets or natural satellites that are not self - luminous.In this case, the eclipsing body intervenes between the sun and the eclips ed object. The other celestial body remains in view of the observer, but its illumination by the sun is interrupted, and it becomes darkened by entering into the shadow of the eclipsing object. Examples of this kind of eclipse phenomenon are eclipses of the Moon (This is known as a lunar eclipse). A lunar eclipse occurs when the Moon travels through the shadow of the Earth and loses its bright illumination by the Sun. It can occur only at the time of the full Moon (For example, when the Moon is directly opposite the Sun), because the Earths shadow is directed away from the Sun. A lunar eclipse can be seen from any place on the Earth where the Moon is above the horizon. Such an eclipse can be total or partial, depending on the Moons position. If the Moon passes through the center of the Earths umbra, a total lunar eclipse occurs. Totality may extend up to one hundred minutes, with the entire elapse lasting about three and a half hours. Solar and lunar eclipses have long beenShow More Related Analysis of Human Perception Essays1040 Words   |  5 PagesWhen it comes down to our understanding of the world it is ultimately the result of our sensual means of perception. In other terms, can we really trust the truth, or anything that we know of scientifically? What does it mean to know something is true and also why it is important to distinguish between what you know and do not or cannot know? It is very difficult to be able to believe everything you hear, unless you experience it for yourself.

All this said, the ol’ theology student in me still twinges a little bit during these trips. I used to be quite critical and found issues with lots of superfluous areas, but even after maturing deeper and understanding better a niggle still remains. It’s a little like there’s something missing, a foundational something that should be holding the pieces together more coherently. And I think I may have finally just put my finger on it.

The basic idea of this agile software development life cycle is to develop a system or a process through repeated cycles with smaller portions at a time. This will help the software developers to have a good understanding of what they have learnt during the development phases than the earlier versions of the system. The possible advantage of the iterative and the incremental model combined is that with each and every iteration design modifications are to be madeRead MoreThe Aztecs And The Incas1135 Words   |  5 Pagesthe Maya and Aztec. Progressively you see that each successive civilization impacted the next in aspects of the religion and the astronomy. The astronomy that the Aztecs and the Maya developed was phenomenal. They were both great at predicting eclipses, as well as being the civilizations with the most accurate synodic periods of the Moon, Earth, Venus, and Mars at that time period. Clearly these people knew what they were doing and what they were looking at. Astronomy was such and important pieceRead MoreExplanation And Prediction Of The Human Sciences And Natural Sciences Essay1593 Words   |  7 Pagesnatural sciences use explanation as a prerequisite for prediction, this procedure shouldn’t be used as the model by which one arrives at new knowledge. Instead we should be critical of the process and the link between explanation and prediction. Understanding that it is possible to predict new knowledge without explanation. At the heart of this question lies the ambiguous nature of both explanation and prediction in their definition. Explanation in the simplest form; is a response to the question whyRead MoreAncient Greek Astronomy Essay1538 Words   |  7 PagesThales, supposedly the first of the philosophers. Various inventions and discoveries are attributed to him, most famous of which is his prediction of an eclipse of 585 BCE. Modern scholars are fairly sure he was able to do this by consulting known Babylonian eclipse and lunar observations going back about 150 years, long enough to notice that eclipses recur after about 18 years.

Since, this supports using technology on the airplanes for the use of the taxiway and runway, which brings both fuel savings and emissions reductions
