Page 160 - Every particle of matter in the universe attracts every other particle with a force that varies directly as the product of their masses, and inversely as the square of the distance between them.
Page 160 - Every body continues in its state of rest, or of uniform motion in a straight line, unless it is compelled to change that state by forces impressed upon it.
Page 48 - Every particle of matter, in the universe, attracts every other particle with a force, which is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
Page 127 - The squares of the periods of revolution of any two planets are proportional to the cubes of their mean distances from the sun.
Page 147 - Map Projection — A systematic drawing of lines on a plane surface to represent the parallels of latitude and the meridians of longitude of the earth or a section of the earth. A map projection may be established by analytical computation or may be constructed geometrically...

Page 96 - ... geodetic meridian. A line connecting points of equal geodetic longitude. Also called geographic meridian. See astronomical meridian. geodetic parallel. A line connecting points of equal geodetic latitude. Also called geographic parallel. See astronomical parallel. geodetic position. A position of a point on the surface of the earth expressed in terms of geodetic latitude and geodetic longitude.
