Nadir also refers to the downward-facing viewing geometry of an orbiting satellite, [2] such as is employed during remote sensing of the atmosphere, as well as when an astronaut faces the Earth while performing a spacewalk. A nadir image is a satellite image or aerial photo of the Earth taken vertically.
Zenith stars (also "star on top", "overhead star", "latitude star") [8] are stars whose declination equals the latitude of the observers location, and hence at some time in the day or night pass culminate (pass) through the zenith. When at the zenith the right ascension of the star equals the local sidereal time at your location.
In topography, a nadir is a point on a surface that is lower in elevation than all points immediately adjacent to it. [1] Mathematically , a nadir is a local minimum of elevation. A nadir may be the lowest point of a dry basin or depression , or the deepest point of a body of water or ice .
It is also used in surveying, to establish the nadir (opposite of zenith) with respect to gravity of a point in space. It is used with a variety of instruments (including levels, theodolites, and steel tapes) to set the instrument exactly over a fixed survey marker or to transcribe positions onto the ground for placing a marker.

Geometry is a branch of mathematics concerned with questions of shape, size, relative position of figures, and the properties of space. Geometry is one of the oldest mathematical sciences. Geometry is one of the oldest mathematical sciences.
The book advocates replacing the usual basic quantities of trigonometry, Euclidean distance and angle measure, by squared distance and the square of the sine of the angle, respectively. This is logically equivalent to the standard development (as the replacement quantities can be expressed in terms of the standard ones and vice versa).
In algebraic geometry, a lemniscate (/ l ɛ m ˈ n ɪ s k ɪ t / or / ˈ l ɛ m n ɪ s ˌ k eɪ t,-k ɪ t /) [1] is any of several figure-eight or ∞-shaped curves. [ 2 ] [ 3 ] The word comes from the Latin lēmniscātus , meaning "decorated with ribbons", [ 4 ] from the Greek λημνίσκος ( lēmnískos ), meaning "ribbon", [ 3 ] [ 5 ...
