Direct projection of 3-sphere into 3D space and covered with surface grid, showing structure as stack of 3D spheres (2-spheres) In mathematics, a hypersphere or 3-sphere is a 4-dimensional analogue of a sphere, and is the 3-dimensional n-sphere. In 4-dimensional Euclidean space, it is the set of points equidistant from a fixed central point.
Earth systems and examples of Earth system interactions across mountain belts. Earth system interactions across mountain belts are interactions between processes occurring in the different systems or "spheres" of the Earth, as these influence and respond to each other through time.
Earth system science – Scientific study of the Earth's spheres and their natural integrated systems; Extraterrestrial life – Life that does not originate on Earth; Information metabolism – Psychological theory of interaction between biological organisms and their environment; Organism – Individual living life form
As just one example of the centrality of climatology to the field, leading American climatologist Michael E. Mann is the Director of one of the earliest centers for Earth System science research, the Earth System Science Center at Pennsylvania State University, and its mission statement reads, "the Earth System Science Center (ESSC) maintains a ...
Component spheres that represent a significant portion of an ecosphere are referred to as a primary component spheres. For instance, Earth 's ecosphere [ 1 ] [ 2 ] consists of five primary component spheres which are the Geosphere , Hydrosphere , Biosphere , Atmosphere , and Magnetosphere .
The Second International Conference on Closed Life Systems defined biospherics as the science and technology of analogs and models of Earth's biosphere; i.e., artificial Earth-like biospheres. [8] Others may include the creation of artificial non-Earth biospheres—for example, human-centered biospheres or a native Martian biosphere—as part ...
Sustainability is regarded as a "normative concept".[5] [22] [23] [2] This means it is based on what people value or find desirable: "The quest for sustainability involves connecting what is known through scientific study to applications in pursuit of what people want for the future."
There are two possibilities: if =, the spheres coincide, and the intersection is the entire sphere; if , the spheres are disjoint and the intersection is empty. When a is nonzero, the intersection lies in a vertical plane with this x-coordinate, which may intersect both of the spheres, be tangent to both spheres, or external to both spheres.
