Longitude: The True Story of a Lone Genius Who Solved the Greatest Scientific Problem of His Time is written by Dava Sobel. The book is called Longitude because it is about a clock maker who was able to determine longitude. Determining longitude was the superlative scientific question in the eighteenth century that Galileo and Newton were not able to resolve.      The principal inspiration behind the invention completed in this book is that many sailors were lost at seas

point can be calculated. It is key to always begin facing north is the bearing calculated is to be found in the true north format. The use of the Geographic Coordinate System is also a common use in society, this system uses two sets of numbers (longitude and latitude) to locate and identify every single spot of the Earth to a certain extent of decimal places. This is the most commonly used system to plot the coordinates of a place on Earth, it is also the most accurate system known to humanity. The

are: Latitude: __40_° _30__' _29__" N, Longitude: _80__° _12__' _26__" W The geographic coordinate system is used to show a specific position on the earth’s surface. It uses longitude and latitude, which are like x and y on a graph, to express the value of the coordinates. Longitude and latitude are curved to help show the shape of the earth. Longitude runs north and south between the prime meridian. Latitude runs east and west parallel to the equator. Longitude and latitude are expressed in degrees

TRUE BEARINGS AND THE GEOMETRIC COORDINATE SYSTEM Investigation   Introduction A true bearing is a mathematical term used to define the point of the angle measured in degrees, in a clockwise direction, from the north point. A true bearing must always be written using 3 figures, for example, it is written as 042° rather than 42°. True bearings are used for specific purposes relating to coordinating geography mapping and navigation. A geographic coordinate system is properly known as “GSC” is a

Tools used to measure latitude (Lesson 02.01) (use the first resource in this lesson to help you) Be able to list and describe the 3 main tools used to measure latitude in early navigation Sextant- allowed users to determine their latitude to within a sea mile or two The gnomon or sun-shadow disk- operated like a sundial, enabling the user to determine his latitude by the length of the sun's shadow cast on a disk floating level in water. The Arabian kamal- a rectangular plate that one moved

Our method for determining the center of mass of each state is split up into five steps. The first two, file conversion and sorting, gave a huge amount of raw data, and then condensed it into a workable form. The third step converted latitude and longitude coordinates into kilometers. The fourth step took the trapezoids formed by the previous steps and calculated their moments with respect to the x and y axis’s. Finally, the conversions were reversed to give the center of mass. All of the states were

(vertical) and latitudinal (horizontal) lines and make analogies with the X/Y Coordinate Plane (Graphic Organizer). You may choose to show one of these two videos to help students understand latitude and longitude: https://youtu.be/cTrsvGytGG0 (~7min) https://youtu.be/swKBi6hHHMA (~3 min) a. Latitude, Longitude b. Address of locations on the earth c. X-Axis: The Equator – units are in 150 increments d. Y – Axis: Prime Meridian – units are in 150 increments e. Upper Quadrants of the X/Y Coordinate Plane

So, to convert location address into longitude and latitude coordinates, there is a number of ways to accomplish this. You may have a GPS device which shows you these coordinates, and you could just take a reading from the GPS while at the address and note down the coordinates. There are also

As I entered the doors of International Newcomers Academy (INA) for the first time, I can remember how nervous I felt. I could not help but feel unprepared and I could not fathom how I could possibly be any help to a student when we did not even speak the same language. However as quickly as my field experiences began I could feel my perceptions changing. The experiences I had at INA have left their mark on me and I am truly grateful for having the opportunity to complete my field experiences at
