Some models of real and fictional weapons and of scientific or anatomical subjects in this scale. >1:1 Larger than life-size. Some models of scientific or anatomical subjects in these scales.
Paul Dirac. The Dirac large numbers hypothesis (LNH) is an observation made by Paul Dirac in 1937 relating ratios of size scales in the Universe to that of force scales. The ratios constitute very large, dimensionless numbers: some 40 orders of magnitude in the present cosmological epoch.
Planck length; typical scale of hypothetical loop quantum gravity or size of a hypothetical string and of branes; according to string theory, lengths smaller than this do not make any physical sense. [1] Quantum foam is thought to exist at this scale. 10 −24: 1 yoctometer 142 ym Effective cross section radius of 1 MeV neutrinos [2] 10 −21: ...
In physics, the microscopic scale is sometimes regarded as the scale between the macroscopic scale and the quantum scale. [2] [3] Microscopic units and measurements are used to classify and describe very small objects. One common microscopic length scale unit is the micrometre (also called a micron) (symbol: μm), which is one millionth of a metre.
Spatial scale is a specific application of the term scale for describing or categorizing (e.g. into orders of magnitude) the size of a space (hence spatial), or the extent of it at which a phenomenon or process occurs. [1] [2] For instance, in physics an object or phenomenon can be called microscopic if too small to be visible.
Size in general is the magnitude or dimensions of a thing. More specifically, geometrical size (or spatial size) can refer to three geometrical measures: length, area, or volume. Length can be generalized to other linear dimensions (width, height, diameter, perimeter). Size can also be measured in terms of mass, especially when assuming a ...
There is no fixed dividing line between small and large scales.) A scale model is a representation or copy of an object that is larger or smaller than the actual size of the object being represented. Very often the scale model is smaller than the original and used as a guide to making the object in full size. —
In 2012, Cary and Michael Huang released a sequel titled The Scale of the Universe 2, in which clicking on objects brings up infoboxes that display information about them. [6] [7] [8] The current version of The Scale of the Universe 2 uses Pixi.js instead of Flash, ported by Matthew Martori. [6]
