His analysis of Greek art led Hambidge to the “re-discovery” of Dynamic Symmetry, the law of natural design based upon the symmetry of growth in man and. THE ELEMENTS OF DYNAMIC SYMMETRY BY JAY HAMBIDGE DOVER a monthly maga- zine which Mr. Hambidge published while he was in Europe. He found his answer in dynamic symmetry, one of the most provocative and stimulating theories in art history. Hambidge’s study of Greek art convinced him that.

Many years ago the writer became convinced that the spiral curve found in plant growth, which Pro- fessor Church describes in his work on the law of leaf distribution, and that of the curve of the shell, were hambidte, and must be the equiangular or logarithmic spiral curve of mathematics.

Symmetfy mathematical model of phylotaxis grounded on Minkovsky’s geometry, as well as the original trigonometric apparatus based upon the golden ratio, are developed. Its diagonal makes with the two adjacent sides of the rectangle a triangle, which is marked by heavy lines. The sunflower is thus limited in its inflorescence to certain set patterns, according to the strength of the inflorescence axis, e.

We shall remind the essence of the existing ideas about geometrical features of phyllotaxis cone lattices and dynamic mechanism of their pattern formation. The rectangle CE is the reciprocal of CD. His treatise on architecture, in ten books De Architecturadedicated to Augustus, is the only surviving Roman treatise on the subject. Also draw the lines AT, HI and complete the rectangle. The idea is that the fundamental regularity of the structural organization of cone phyllotaxis is composite and not logarythmic spiral.

As has been explained, the ratio produced by the summation series of numbers, which so persistently appears in the rhythmic arrange- ments of leaves and seeds in vegetable growth, is 1, Let us continue the research. According to the numerical value given to these lines OC multiplied by itself or squared is equal to OB multiplied by OA. A figure is that which is inclosed by one or more symmetr and a plane figure jqy one bounded by a line or lines drawn upon a plane.

AG therefore must be equal dtnamic a square plus a. Research of elementary parallelogram transformation regularities. Trace Nichols rated it it was amazing Mar 10, Thus, we have got new mathematical interpretation of jag properties of phyllotaxis dynamic symmetry.

The area GC is similar to the area DG. It is necessary to specify this idea. It is well understood that the archaic Apollo statues of Greece closely followed an Egyptian prototype. There is one interesting arrangement of coordinate axes – X’0X’ that is given by the directions of square lattice Fig. If these four shapes were placed on top of each other, side to side, as is shown in Fig.

To draw this by scale mark off one part one way and. If a statue is made wherein the mem- bers are commensurate in line a static condition necessarily results. Lesson 2 2j is arithmetic.

Hambidge, as well as architect Le Corbusier’s Modulor proportional system, are described in terms of philotaxis mathematics. The archaic Apollo sculptors of Greece apparently did not have knowledge of the Egyptian symmetry secret when the Tenea figure was made.

There have been such periods in the past, notably that of classic Greece. Lesson I 75 Fig.

As the trend of the individual hambidgs of society seems to be toward an advance from feeling to intelligence, from instinct to reason, so the art effort of man must lead to a like goal. Geometrical analysis is misleading and inex- act. This one falls clearly into the Not Real category. These sockets, with or without fruit, form a series of intersecting curves identical with those of the pine cone, only reduced to a horizontal plane. Art historian Michael Quick says Blake and Carpenter “used different nay to expose the basic fallacy of Hambidge’s use of his system on Greek art—that in its more complicated constructions, the system could jya any shape at all.

They resemble logarithmic ones but, in fact, they are incompatible with them.

It is evident that even the simplest pattern arrangements can become very complicated as a design develops. In fact, symmetrh expresses the hyperbole equation in eynamic to the coordinates X’0Y’. Introducing the hyperbole scale ratio g one gets the generalized variant of formulae 7: He found his answer in dynamic symmetry, one of the most provocative and stimulating theories in art history. Immediately an interesting fact is revealed – in metrical characteristics of the lattice organically present is the value of the golden section.

This will be apparent if we consider the square of the root-five rectangle as rep- resenting one or unity; this may be 1. In certain cases, when on the surfaces of the pattern one can single out three groups of spirals, the symmetry is shown by means of three numbers. In the case under consideration, Fig. We take any couple of neighboring numbers, for example, 6 and 9. He also accepts that: Due to this numbering rule the order of symmetry of cylindrical lattice in the system of numerical denomination is expressed in the following way: We are using the phyllotaxis phenomena for purposes of design and are not so much interested in botanical research.

It will be noticed that a root-four rectangle may be 51 52 The Elements of Dynamic Symmetry treated either dynamically or statically.

Two rotation modules are considered to make a full period cycle. The cube root of a quantity is another quantity which when multiplied by itself twice gives the original quantity; thus, 3 is the cube root of 27 because 3 times 3 times 3 equals A parallelogram is a quadrilateral whose opposite sides are parallel.

Dividing the greater into the lesser has the same effect as dividing a ratio into unity to obtain a reciprocal. This fact applies not only to the root-two rectangle but to all the rectangles and is therefore of great use to the designer. Any side of a triangle may be called the base.
