  • Navigating the Compass
    Navigating the Compass How does a compass work? Most of us have a compass somewhere in our house, but may never use it! A compass is a tool to help you get from one place to another (or navigate) by indicating direction. This happens when a magnetized needle lines up with the magnetic poles of the Earth, which are at the North and South of our planet (like the North pole and the South pole). Think of the way a magnet sticks to your fridge – the magnet is drawn towards the fridge, the same way as this needle is drawn towards the North magnetic pole. Some birds even use this magnetic field to know which way to migrate. Navigators use the four cardinal directions, North, South, East and West to make their way from 1 point to another. Today, magnetized needles you see will have a red or white line that lets you know which ways is North. North – East – South – West are the directions of your compass. I remember the order by going around the compass clockwise while saying Never – Eat – Soggy – Waffles! History of the Compass Scientists and historians believe that the Ancient Greeks understood magnetism, and that the Chinese may have begun magnetizing needles over 2,000 years ago. The first compasses were made from sticking a magnetized needle onto a wine cork and then letting it float in water. The needle would spin and point towards North. Before these compasses were widely used in travel, people relied on the sun (which rises in the East and sets in the West), the stars and major landmarks to navigate.

  • China's Gifts to the West
    CHINA'S GIFTS TO THE WEST Prepared by Professor Derk Bodde for the Committee on Asiatic Studies in American Education Reprinted with permission in China: A Teaching Workbook, Asia for Educators, Columbia University Introduction An exercise identifying Chinese inventions that we use and enjoy in daily life provides an excellent starting point for discussing both the achievements of the Chinese civilization and China's influence on the West. The article China 's Gifts to the West describes China's inventions of silk, tea, porcelain ("china"), paper, printing, gunpowder, the mariner's compass, medicines, lacquer, games (including cards, dominoes, and kites), and miscellaneous items such as umbrellas, as well as natural resources, such as plants (including peaches, apricots, and citrus fruits) and minerals (including coal and zinc), first discovered and cultivated by the Chinese. Lesson Ideas: For homework, have the students look up several items on the above list in an encyclopedia to see if they can identify their origin. Then use the article China's Gift to the West to enrich the story of how each invention was brought to the West. A second approach might be to assign individual students one invention to read about in China's Gift to the West and report to the class. A separate chapter is devoted to each of the items/inventions in the list above. Foreward In 1940 almost 10,000 new books were printed in the United States. Millions of copies of the 13,000 newspapers in the country were distributed. All of this was possible because we know how to make paper and to print with movable type — inventions which occurred in China.

These publications ranged from brief extracts of romantic narratives involving shipwrecks in the East Indies to multi-volume compilations of voyages to all parts of the world, printed in folio and containing numerous maps and engravings. Existing scholarship often views such accounts as entertainment destined for a popular audience. This dissertation shows how the voyage account was used in multiple genres and multiple intellectual contexts, finding its way into debates about natural philosophy, religion, and history, and playing as important a role in the work of the Royal Society as it did in the literary practices of the period.

    A CALL TO ARTISTS Design a Compass Rose for the Cottonwood Municipal Airport! The City of Cottonwood Municipal Airport is calling all local artists to submit an original design for an aeronautical compass rose. The winner will paint their compass rose on the ramp at the Airport at approximately 50 feet in diameter as part of the national airmarking program. In addition to aesthetic appeal and creativity, the design must also incorporate the technical requirements of a usable compass rose. Artists are encouraged The History of the Compass Rose to provide a design that The Compass Rose first appeared on ships’ navigational charts around 1300. The term “rose” incorporates the essence stems from the fact that the design looks like rose petals.

  • The Art and Science of the Compass Rose by Eliane Dotson
    Collector's Corner: The Art and Science of the Compass Rose by Eliane Dotson Often the central focal point of a map, the compass rose has played an important role through the centuries with regards to both cartography and navigation. However, one must first know a little of the history of the compass before one can understand the origin of the compass rose. History of the Compass Although the exact origin is unknown, there were several discoveries that led to the creation of the compass. The basic compass requires a magnet that reacts to the earth's magnetized field, and will physically align itself with the magnetic poles (in a north/south orientation). The only naturally occurring mineral on earth to exhibit strong magnetic properties is magnetite, and a magnetized piece of magnetite is called a lodestone. The magnetic properties of the lodestone were known to the ancients, as evidenced by the writings of Plato and Euripides, and were also known independently by the Chinese, possibly as early as 1100 BC. The first primitive compasses using lodestones were believed to have been created by the Chinese around 140 AD to be used for the purposes of spiritual life. Various rudimentary forms of compasses were used over the next millennium, both for spiritual aligning and for basic orientation and navigation. Knowledge of the compass is believed to have made its way to the Mediterranean around the 12th century, with Italy presumed to be the entry point. The first written description of a freely pivoting compass needle (in contrast to earlier known floating apparatus) came from Petrus Peregrinus de Maricourt, a French scholar, in 1269.

  • Directions, Courses, and Bearings: the Compass
    Directions, Courses, and Bearings: The Compass Jeff Cassidy, Steel City Sailing (jeff@steelcitysailing.ca) Ever since explorers and travellers have ventured beyond their familiar landscape, they have needed to know which way they were going. The need is particularly acute on the water where there are no paths to follow and often no landmarks on the horizon. Ancient civilizations such as the Polynesians were able to accomplish remarkable feats of navigation over many millennia by relying on their knowledge of stars, migratory bird movements, ocean swells, currents, trade winds, and faint signs of remote land such as clouds. More modern navigation has benefitted tremendously from the application of the magnetic compass for marine navigation in ancient China (approx 12th century), providing a simple way to determine orientation in reference to the Binnacle compass on a sailing yacht. The compass compass needle. card (blue, with cardinal points and numerical headings marked) is free to rotate and keeps itself oriented towards compass north as the vessel turns. The lubber line (yellow) is fixed to the What do we mean by housing on the vessel and used to read the current “North”? heading. The answer is surprisingly tricky, and has evolved from ancient times to present. The briefest and easiest definition to understand is that it is the name given to one of the two ends (poles) of the axis around which the Earth rotates. Using a right-handed coordinate system, true north is the positive orientation for that rotation. At any point on or near the surface of the Earth then, (true) north is the direction towards the (true) north pole.

  • Sparavigna, A. (2017). Magnetic Compasses and Chinese
    Magnetic Compasses and Chinese Architectures Amelia Carolina Sparavigna Department of Applied Science and Technology, Politecnico di Torino DOI: 10.5281/zenodo.1250461 Abstract In this paper, we are discussing the effect of the use of magnetic compasses on the orientation of ancient Chinese architectonic complexes. As Czech researchers proposed in 2011, assuming these complexes ideally oriented by the ancient architects along north-south direction, in the case that the surveys were made by means of magnetic compasses, we can find the axes of the complexes deviating from the cardinal direction, according to the local magnetic declination that existed at the time the structures were built. Following this idea, here we discuss some examples of possible alignments obtained by means of magnetic compasses, concluding that the Chinese surveyors adopted, during the Ming dynasty, a method based on the magnetic compasses. The architects of the antecedent Yuan Dynasty probably used an astronomical method. Keywords: Architectural Planning, Magnetic Compasses, Magnetic Declination, China, Satellite Images, Google Earth, Yuan Dynasty, Ming Dynasty, Beijing, Forbidden City, Temple of Heaven, Temples of Earth, Sun and Moon. An axis exists, known by the Latins as the "axis mundi" (the cosmic axis), about which the vault of the Heaven seems rotating. This axis, projected on the Earth surface, is giving the cardinal north- south direction. Some ancient monuments show that this axis was considered as very important. The Egyptian pyramids of Giza, for instance, were remarkably aligned along it by the ancient surveyors that used the rising and setting of stars or the shadow of a gnomon to find the true North [1].
