First Topic: Mind and Body Interface Revisited Author: Mounjia Abdeltif School of Architecture of Algiers, Algeria Title: Heritage is teaching: the « Turning » house. Twentieth century seems to be a period of big failure in matter of architecture and urban design, almost everywhere in the world. In the thirties, CIAM philosophy stated that the housing place will be a machine. They decided for all societies that function will be the basis of design of forms. These thoughts led to reduction, poverty of forms, simplification and divorce with LAWS OF NATURE. After Second World War, people lost the ability to dwell (Heidegger, M.) and to inhabit houses. Every body accepted to live in a “unit” without soul or any sustainable quality. No more complexity, holistic ideas disappeared. Buildings are rigid and dead. Today the world is getting more aware of this reality. Scientists are willing to connect in order to rebuild a web of knowledge and to go back to genuine and timeless way of building (Alexander, C.). Consequently, heritage is becoming a great treasure in most countries. They are valuing, preserving and restoring a lot of buildings and cities of the past. Memory and culture are the truest wealth. In nature, in all scale (visible and non visible) everything is moving and turning. Galaxies, sun and earth, moon and earth, design of flowers, plants, fruits, DNA, etc. In Islamic tradition, people turn around Kaaba seven times. Turning movement has an esthetical potential like DNA molecule which is a helix. Beauty is related to golden proportion present in most natural organisms. In our research, we have been studying the eighteenth century house of Algiers. At different scales, from the whole shape to the drawing of a ceramic tile, its design is a “turning” form: sculpture of doors, arrangement of rooms around the courtyard, twisted columns, spirals everywhere, etc. Golden proportion is governing the construction. Its name is “DAR”, coming from “DAARA”, which means “to turn”! Now, we can understand why the feeling of beauty is so objective and so direct. Our brain is made to accept mathematical beauty that comes straight from deep laws of eternal nature. The future design of architectural places must refer and learn from timeless rules that have always kept our universe in movement. Keywords: heritage, fractals, belonging, movement, house, timelessness. 1 Mouvement Immobility Immobility Scheme of the traditional house of Algiers: a helical design. 2 In nature, in all scale (visible and non visible) everything is moving and turning. Galaxies, sun and earth, moon and earth, design of flowers, plants, fruits, DNA, etc. In Islamic tradition, people turn around Kaaba seven times. Turning movement has an esthetical potential like DNA molecule which is a helix. Beauty is related to golden proportion present in most natural organisms. « The drop of water knows that it is inside the ocean; but does it know that the ocean is inside her?” Oriental old saying “We live for the sake of beauty, what is left is: waiting”. Khalil Gibran 1- Problematic Actually, “How can we design “immobility” as an answer to “everything must move”? Because when, meanwhile, more things and subjects move, some things do not move at all”, is the best problematic and introduction to our work. When architects evaluate ancient architecture that became world’s heritage, they must look for hidden rules. These rules have the strength and power to generated wholeness and genuine objective beauty. At that time, builders were using golden proportions, Fibonacci mathematics and other natural measuring systems at all scales. What happened in the meantime? What’s wrong with our cities and our architecture? Is Modernist ideology (Charter of C.I.A.M., 1933) guilty or should we go back to other historical circumstances and socio-economical events like industrial revolution? 2- Theoretical Framework These twenty last years, in schools of architecture, everywhere in the world, theoretical projects start to gain awareness about “immobility” of designed places. People are developing a lot of methodological processes that take Natural Forces in account. Many fields like computer sciences, building sciences, urban design, architecture and some human sciences are using fractals in generative processes. Fractals are, hopefully an efficient way to explore architectural places as a scale between macro and micro (from universe to DNA). Multiplicity of scales, symmetries and hierarchy, help researchers to escape from reductive methods that generated rigid and dead urban spaces. Fractals are a new science; they are not a new knowledge. A lot of researchers re analyzed well-known buildings designed by Viollet-Le-Duc, Andrea Palladio, Antonio Gaudi, Le Corbusier, and Frank Lloyd Wright. They found out that they used fractal geometry in their design even if they did not have computing tools. Some artworks made by famous painters like Leonardo Da Vinci, Mondrian and Salvador Dali also used fractals in paintings composition. Today, since computer science is so performing, scientists can go faster in their discoveries and works. Movement is easily perceived while using models and simulation experiments. Architectural design is able to show clearly how space can be built with harmony and objective rules, using “the timeless way of building” (Christopher Alexander, 1979). Moreover, holistic science orders to admit and work with the idea of DNA: The part is in the whole and the whole is in the part. The concept of “belonging” can at last be scientifically demonstrated. The only way to understand the quality of living organisms is to use the theory 3 of complexity. A local complex system could not be decomposed or disconnected from the global system it belongs to. Otherwise the intelligibility and wholeness would break. 3- From cell to galaxies: It is important to say that these two extreme scales do not have limits. Only human knowledge is limited while evolving. Man has always been trying to understand natural phenomenons. He invented tools and explored life from the infinitely small to the infinitely large. But knowledge doesn’t have limits. Sciences should help scientists find God (Christopher Alexander in “Nature of Order”, 2003). Biology is not an isolated science according to the fractal logic (auto similarity and symmetry of scale). Biological morphogenesis is related to phenomenon of the whole structure of Universe (James Gleick). Sun has generated galaxies which exist because of him. Sun and planets are connected in a whole system. One needs the other for sustainability and existence. Planets are related and sustain each others. This organization is true until DNA molecule in all living organisms. Universe is a whole fractal system where each part occupies a specific and precise place in order to sustain the large field-like structure (Christopher Alexander, 2003): the diagram of forces (D’Arcy Thompson). This living world keeps constantly moving. Actually, each part is moving around a centre. This system is isotropic or stable because it is moving that way. 4- Movement Concerning universe, the most interesting law is ROTATION. This action is related to space and time. Galaxies are spiral movement DNA M= E/T (movement is space divided by time) Laurent Nottale found out the theory of “fractal space/time”. Definitely, from macro scale to micro scale, universe is a fractal system. All rotations are connected and no separable like 4 sewed in a strong whole diagram of forces. Each fractal structure generates the next one and the new one, auto similar, will announce the next one. Galaxies and cells belong to one system: Our complex Universe. 5- Our universe is “lazy”: Two basic laws are sufficient for its life and evolution: - Universal resistance (cosmic constant R: the cause): it is absolute. Universal attraction (cosmic constant G: the effect) Since these two laws iterate constantly, the universal structure is actually FRACTAL. The more change occurs, the more it is similar. Whatever the scale is, structure resembles. Iteration or repetition or resonance is the same concept. One referential iterating structure proves that our universe is lazy. We can now make a statement: fractals and isotropy are the same. There are two types of resonance: one coming from waves and the second coming from rotation of objects. 6- About helical shapes “Helical shapes, symbolizing ascension while turning, have always fascinated people”, Claude Piguet, the “father” of “helicates”. He worked on DNA molecule which is a double helix. Scientists have found out the shape of DNA for sixty years. We can notice today that from galaxies to micro organisms, the turning movement is an evident reality. Between these two scales, there are all human perceivable territories. If ancient builders were using nature in their design, what probably were their references? - The nautilus: this spiral is constructed on the basis of golden number (1, 618) - The pine cone: Fibonacci series is identified, - - 5 The “romanesco” cauliflower: spiral arrangement, Sunflower: Daisy flower Dahlia - Ananias A plant These are few examples of mathematical arrangements in Nature. In the nineties, the scientists’ researchers, Couder and Douady could design computerized models of plants design. A double spiral ! Finger prints and auditory system: their morphogenesis is based on spirals. 7- Golden Proportion (1, 618) Behind spiral and helical shape there is the most mysterious mathematical phenomenon: the Golden proportion. This proportion is divine and regulates our whole universe, at all scales. Obviously, for thousands years, old civilizations used this proportioning system. When builders wanted to reach eternal and objective beauty, they used it in their architectures: Pyramids in Egypt, Taj Mahal in India, Parthenon in Greece, etc. Parthenon in Greece Cheops pyramid Modulor “Nature is mathematical”, Le Corbusier (he invented the Modulor, a measuring system based on the golden proportion. 6 Even DNA, 5th symphony of Beethoven and sonatas of Mozart are based on Phi, golden number. When aesthetic rules use this number as basic measure that comes from laws of Nature, beauty emerges through unfolding processes. Since all subdivisions of human arm are related with golden number, they form THE measure inside the FOOTSTEP. Two arms equal one footstep. In ancient times builders used to use tools that correspond to these proportions. The golden rectangle In Arts, famous Renaissance artists used this golden proportion (Leonardo Da Vinci and others). Conclusion: Fibonacci series and golden proportion are tools that mathematicians gave to humanity in order to design works of Art which have the power to make genuine beauty emerge and create an emotion felt by all human beings through senses and brain. All traditional architectures in our world are valuable places that people admire and respect. We have to go back to their secrets and think about future rules for our contemporary cities where the most serious crisis is ugliness. 8- The “turning” house (DAR1) of Algiers (18th century: Ottoman Era) 1 This arabic word comes from the verb « daara » which means: to turn. 7 - At the scale of the house, the central courtyard with its surrounding gallery is the heart of the whole system (ref. the scheme that shows the plan). The rooms are arranged in a spiral organization around the courtyard. The walls of this courtyard are the actual façades of the house. In Moslem societies, beauty is expressed in interiors. Exterior walls are humbly designed. Inwardness is a value and a concept. Materials are noble (ceramics, marble, wood, iron) and arrangement are made with refinement and taste. In this rich interior, we could find golden proportion everywhere: heights and widths at different scales. When we live in this intense space, we feel the movement of spiral and the ascension toward the sky (open courtyard). From the ethical point of view, ALL families have the right to be connected to the sky. - At the scale of the centre (“West Ed Dar” in Arabic), twisted columns look like DNA molecule. These columns could be built with stone or marble. At that time a lot of house owners use to order their columns in Italy. Italian craftsmen were sending them by boat. At the top of these columns, there are 8 spirals recalling roman arrangement. History is complex. Civilizations learn from each other’s and make architecture and art progress over time and space. When we live in this magic place (the courtyard), we are surrounded with turning shapes everywhere. 8 - At the scale of a door, the design of sculpture is exactly the plan of the house: - At the scale of a tile, the design is helical. 9- Concluding remarks: The “turning” shapes are appearing at different scales: IT IS A FRACTAL phenomenon. Interiority is a basic concept in Muslim societies. It suggests a special geometry: the SPIRAL. The “DAR”of Algiers in 18th Century is A PART of our universe according to the fractal theory. Spiral is an infinite movement around a centre. Our universe is fractal and contains a lot of turning bodies. It is moving through physical simple laws: attraction and resistance= rotation. On earth, all living organisms are connected. They follow the same laws. Complex phenomenons of life are not all visible from a human eye. If architecture uses these natural laws, it is then connected to the universe; therefore it becomes a frame for timeless quality of life. Over time, civilizations have a basic thing in common: GOLDEN PROPORTION. Designers must use this valuable tool in order to recover the objective beauty that we lost during the twentieth century, in Architecture and Arts. For our societies, genuine beauty is the most serious therapy: “Beauty will save the world”, Leon Tolstoy 10- References Akbar, J. (1988). Crisis in the Built Environment. New York: A Mimar Book.
