Here we will carry out numeric calculations, for many different values of and Recall that the basic equation for calculating dimensionĪlthough there is no rule that dimension has to have an integer value, this has been the convention in traditional Refer to such in-between dimensions as the Hausdorff-Besicovitch dimension. Has a dimension of and a square a dimension ofĭimension related to the varying amounts of information they contain. Mathematics refer to reality, they are not certain and as far as they areĪnd Abram Besicovitch(1891-1970) revolutionized mathematics by proposingĭimensions with non-integer values. The Hausdorff-Besicovitch Dimension (top) The calculation of fractal dimension as seen in the following sections. The most common values are andĬenturies later these logarithms would be crucial in Here is a list of logarithm transformations:įigure 4.9 Table of Logarithm Transformations.Ī logarithm's base can have any positive value. Method for multiplying large numbers, along with solving division problems,Ĭalculating powers and roots. Before computers, logarithms were an invaluable The process, he showed how a close approximate product of two numbers couldīe relatively easily calculated. To their corresponding log values, adding them together, and then reversing (represented as log) to simplify multiplication. John Napier (1550-1617) originally invented logarithms Here with logarithms and with iterated function systems in Chapter 5. Mathematical equations too can be transformed. Infinite lengths and triangles within triangles.Īlong with geometrical transformations seen in scaling, Resembles the sea creature, nautilus seen in Figure 3.89 in Chapter 3. Well known spiral with infinite length is the golden mean spiral derivedįrom the ancient Greek's golden ratio see Figure 4.8. Of which the logarithmic spiral is the most famous see Figure 4.7. This idea to show that some spirals could be drawn with an infinite length, Later the mathematician Jacob Bernoulli (1654-1705) expanded Archimedes (287-212 B.C.) used spirals to illustrate repeating He also used self-similar triangles to show the congruency of triangles With infinite lengths to illustrate the concept of parallel lines, there Infinite Lengths and Scale Ability a prelude to fractals.įor example scale ability and line lengths have long been associated with Tools developed over the centuries that help us to understand fractals.
