Word of the day


Fractal – a curve or geometrical figure, each part of which has the same statistical character as the whole; any of various extremely irregular curves or shapes for which any suitably chosen part is similar in shape to a given larger or smaller part when magnified or reduced to the same size; a geometrical or physical structure having an irregular or fragmented shape at all scales of measurement between a greatest and smallest scale such that certain mathematical or physical properties of the structure, as the perimeter of a curve or the flow rate in a porous medium, behave as if the dimensions of the structure (fractal dimensions) are greater than the spatial dimensions; a complicated pattern in mathematics built from simple repeated shapes that are reduced in size every time they are repeated; a never-ending pattern; shapes that seem to exist at both the small-scale and large-scale levels in the same natural object.
