Political map of Europe, showing south at the top. Research suggests that north-south positions on maps have psychological consequences. In general, north is associated with richer people, more expensive real estate, and higher altitude, while south is associated with poorer people, cheaper prices, and lower altitude (the "north-south bias").
The truss structure of the globe made visible during a panel-replacement project in 2023. The globe was completed in 1998, [3] after two years of construction and planning, [4] and it uses a composite database built from satellite imagery, shaded relief, colored bathymetry, and information about road networks and urban areas.
Earth's rotation axis moves with respect to the fixed stars (inertial space); the components of this motion are precession and nutation. It also moves with respect to Earth's crust; this is called polar motion. Precession is a rotation of Earth's rotation axis, caused primarily by external torques from the gravity of the Sun, Moon and other bodies.
In cartography, a conformal map projection is one in which every angle between two curves that cross each other on Earth (a sphere or an ellipsoid) is preserved in the image of the projection; that is, the projection is a conformal map in the mathematical sense.
Find a globe in your local library or classroom and try this: Close the eyes, spin it and drop a finger randomly on its curved, glossy surface. In the age of Google Earth, watches that triangulate ...
When making a conic map, the map maker arbitrarily picks two standard parallels. Those standard parallels may be visualized as secant lines where the cone intersects the globe—or, if the map maker chooses the same parallel twice, as the tangent line where the cone is tangent to the globe. The resulting conic map has low distortion in scale ...
In mathematics, a rotation of axes in two dimensions is a mapping from an xy-Cartesian coordinate system to an x′y′-Cartesian coordinate system in which the origin is kept fixed and the x′ and y′ axes are obtained by rotating the x and y axes counterclockwise through an angle .
The pair assaulted Virk again and ultimately drowned her in the Gorge Waterway under the bridge, according to court documents. Virk's body was found more than a week later on Nov. 22, 1997 ...
