Pages 2
The most commonly accepted origins of magnetism is from a Greek legend. In an area of Northern Greece about 4,000 years ago, an elderly shepherd named Magnes was herding his sheep when he quickly noticed that he and his metal staff were stuck to the ground. He eventually got himself unstuck and looked to find the source of the attraction by digging up the ground around where got stuck. He found lodestones which contain magnetite which was a naturally occuring magnet. The stones were named after Magnes himself.

As time went on, many discoveries on magnetism were made. In 1600, William Gilbert found that the Earth itself was a magnet, with the planet having a north and a south pole. In 1820 Hans Christian Oersted found that electricity was related to magnetism by bringing an electric-carrying wire near a magnetic compass. He observed that the compass’ direction was affected by the position …show more content…
Magnetism is used in Maglev trains which uses magnetic levitation to move the train without touching the ground. By using magnets it is able to be propelled above the ground with very little friction, allowing for high speed transportation. Magnetism is also used in MRI scans (Magnetic Resonance Imaging) which uses magnetism and radio waves to create images of the inside of a person’s body. MRI scans can be used to diagnose many conditions and diseases.

Future technology can use magnetism to improve existing technologies and create newer, more efficient technology. In the web article, “8 Ways Magnetic Levitation Could Shape The Future”, the author Sarah Fecht discusses many different current technologies, such as Wind Turbines and Bearings and then lists the magnetic alternatives that use magnetism to make them more effective, such as magnetically levitated turbines that would allow for higher power gains from turbines as well as magnetic bearings which would eliminate the need for lubrication in motors, generators and

...Hui-Fen Hsu The Heroic Pattern in Life of Pi 95 The Heroic Pattern in Life of Pi Hui-Fen Hsu Applied English Department National Taichung University of Science and Technology Lecturer Abstract This paper examines the universal structure of a mythological hero’s adventure in Life of Pi. The theory is based on Joseph Campbell’s The Hero with a Thousand Faces, which illustrated and distilled heroic patterns from various cultures. The hero’s journey has three stages: separation, initiation, and return. Answering a call to adventure, the hero departs from his familiar world and ventures into a region of supernatural wonder. Miraculous forces are encountered there and a decisive victory is won. He then returns from this mysterious land, bringing an elixir to bene¿t his fellow men. Through this journey of trials, the hero transforms his former self and achieves spiritual growth. Such heroes range from monster slayers to spiritual leaders such as the Buddha and Christ. Life of Pi is a fantasy adventure novel about an Indian boy who survives a shipwreck by drifting on a lifeboat with a tiger. His adventure ¿ts Joseph Campbell’s hero archetype. Similar to the mythological hero, Pi departs from his familiar land of India, answering the call for adventure to a new country. Protected by the supernatural powers of Hinduism, Catholicism, and Islam, he penetrates the dangerous and mysterious realm of the Pacific Ocean. After experiencing harsh ordeals, he returns...
