• Fundamental unit — A set of fundamental units is a set of units for physical quantities from which every other unit can be generated. In the language of measurement, quantities are quantifiable aspects of the world, such as time, distance, velocity, mass, momentum …   Wikipedia

• Fundamental interaction — In physics, a fundamental interaction or fundamental force is a mechanism by which particles interact with each other, and which cannot be explained in terms of another interaction. Overview In the conceptual model of fundamental interactions,… …   Wikipedia

• Constante física fundamental — Una constante física fundamental es una constante física adimensional y que por tanto toma el mismo valor en cualquier sistema de unidades. Eso hace de estas constantes físicas las únicas constantes estrictamente universales (aunque a veces se… …   Wikipedia Español

• Exact trigonometric constants — Exact constant expressions for trigonometric expressions are sometimes useful, mainly for simplifying solutions into radical forms which allow further simplification.All values of sine, cosine, and tangent of angles with 3° increments are… …   Wikipedia

• Dimensionless physical constant — In physics, a dimensionless physical constant (sometimes fundamental physical constant) is a universal physical constant that is dimensionless having no unit attached, so its numerical value is the same under all possible systems of units. The… …   Wikipedia

• Anthropic principle — In astrophysics and cosmology, the anthropic principle is the philosophical argument that observations of the physical Universe must be compatible with the conscious life that observes it. Some proponents of the argument reason that it explains… …   Wikipedia

• Physical constant — A physical constant is a physical quantity that is generally believed to be both universal in nature and constant in time. It can be contrasted with a mathematical constant, which is a fixed numerical value but does not directly involve any… …   Wikipedia

• Planck units — are units of measurement named after the German physicist Max Planck, who first proposed them in 1899. They are an example of natural units, i.e. units of measurement designed so that certain fundamental physical constants are normalized to 1. In …   Wikipedia

• Dimensional analysis — In physics and all science, dimensional analysis is a tool to find or check relations among physical quantities by using their dimensions. The dimension of a physical quantity is the combination of the basic physical dimensions (usually mass,… …   Wikipedia
