natural metric
11metric system — a decimal system of weights and measures, adopted first in France but now widespread, universally used in science, mandatory for use for all purposes in a large number of countries, and favored for use in most (as in the U.S.). The basic units… …
12Natural resources in India — The total cultivable area in India is 1,269,219 km² (56.78% of total land area), which is decreasing due to constant pressure from an ever growing population and increased urbanization. India has a total water surface area of 314,40 km² and… …
13Metric signature — The signature of a metric tensor (or more generally a nondegenerate symmetric bilinear form, thought of as quadratic form) is the number of positive and negative eigenvalues of the metric. That is, the corresponding real symmetric matrix is… …
14Natural disasters in China — China is one of the countries most affected by natural disasters. It had 5 of the world s top 10 deadliest natural disasters; the top 3 occurred in China: the 1931 China floods, death toll 3 million to 4 million, the 1887 Yellow River flood,… …
15Metric tree — This article is about the data structure. For the type of metric space, see Real tree. A metric tree is any tree data structure specialized to index data in metric spaces. Metric trees exploit properties of metric spaces such as the triangle… …

18Natural topology — In any domain of mathematics, a space has a natural topology if there is a topology on the space which is best adapted to its study within the domain in question. In many cases this imprecise definition means little more than the assertion that… …
19metric function — noun a function of a topological space that gives, for any two points in the space, a value equal to the distance between them • Syn: ↑metric • Topics: ↑mathematics, ↑math, ↑maths, ↑physics, ↑natural philosophy …
20Fubini-Study metric — In mathematics, the Fubini Study metric is a Kähler metric on projective Hilbert space, that is, complex projective space CP n endowed with a Hermitian form. In the context of quantum mechanics, for n=1 this space is called the Bloch sphere; the… …
