Introduction Isaac newton—English astronomer‚ physicist‚ mathematician‚ and scientist—became interested in science as a boy and even invented several devises while he was still young. He attended Cambridge University and later taught there. In Optics‚ newton published his principles of light and colour‚ and in his mathematical principles of natural philosophy (also known as the principia)‚ he discussed the laws of motion and the theory of gravity. Besides his scientific study‚ he spent much time

Yale Graduate School Writing Center On-line Tutorial Pre-Writing (This resource was created by Richard Wing‚ Yale University‚ July 2009) Pre-writing is perhaps the most important part of the writing process as it lays a foundation for the writing that is to come. During this stage‚ writers establish the purpose of the work and the audience for whom it will be written as well as their argument and an outline for the piece. It is also a period during which preliminary research on the topic is

Introduction Background Indicators are used in acid-base titrations to determine end points as both acid and base are colourless in nature. However‚ indicators chosen must be suitable according to the type of reactions such as: - Strong acid-weak base titration - Weak acid-strong base titration - Strong acid-strong base titration - Weak acid-weak base titration Only the first two mentioned above will be investigated in this experiment. Aims/Objectives 1. To understand

Chapter I INTRODUCTION Marine life is a vast resource‚ providing food‚ medicine‚ and raw materials‚ in addition to helping to support recreation and tourism all over the world. At a fundamental level‚ marine life helps determine the very nature of our planet. Marine organisms contribute significantly to the oxygen cycle‚ and are involved in the regulation of the Earth’s climate. Shorelines are in part shaped and protected by marine life‚ and some marine organisms even help create new land

Is the sextant a carthorse in the 21st century? Abstract The purpose of this report is to decide whether the sextant is outdated and effectively useless in the modern age or whether it still has a use in modern navigation. To decide this I explored modern navigation techniques‚ which is mostly done by global positioning systems‚ I researched the way that these work and the methodology behind the use of a sextant. The conclusion that I came to was that modern day sextant use is rare
