  • After the time of the Pythagoreans, the Golden Ratio fades toobscurity in history until the Renaissance
  • the Golden Ratio resurfaces around the turn of the 16th century when Luca Pacioli publishes De DivinaProportione- which focused on what has come to be known as the Golden Ratio. Pacioli collaborated and lived with Leonardo Da Vinci,[11] who illustrated De DivinaProportioneLuca Pacioli's 1509 De DivinaProportione, ascribed "holy" or "magical" properties to the Golden Ratio
  • Some say the Golden Ratio was known as far back as 2500 BCE and used in the design of the Great Pyramid of Giza.the ratio of half the base to the pyramid's slant height is within 1% of the Golden Ratio.
  • Da Vinci is thought by some to have used the Golden Ratio in works such as The Vitruvian Man and The Mona Lisa, The Last Supper; but this is widely disputed and no obvious evidence to support it.another popular idea is that flowers have numbers of petals according to the Fibonacci numbers, which is true for some flowers, but also untrue for many others.some people say the human body exhibits Golden proportions.there is too much variance in body shape from person to person to imply that the human form conforms to a precise ratio, at least without concrete evidence
  • The dimensions of the Parthenon vary from source to source probably because different authors are measuring from different points. With so many numbers available, a golden ratio enthusiast could choose whatever numbers gave the best result. (Markowsky, 1992)overabundant hype and hoopla surrounding the Golden Ratio and Fibonacci SequenceTie in with our lecture: Much of this mystic beliefs stem from the Renaissance period, when the Ratio was labeled "Divine" and all things Greek were thought to be good.Remember how Pythagoras believed that all reality could be expressed mathematically and that numbers were sacred and eternal? It made sense that he would buy the idea of perfection of nature and the heavens, using a single ratio. We can see the appeal of such an idea. Even today, many remain fascinated by the Golden Ratio and its many forms of ‘manifestation’ in life.Remember before the Renaissance, people were in awe of the ancient Greeks and their achievements (eg. Parthenon in Athens)? It was fashionable to learn Greek and to learn the knowledge of the ancient Greeks. Renaissance manDa Vinci: keen interest in proportionIt was ‘observable’, and hence the idea can be easily passed on. However, we usually see what we would like to see. It is easy to claim that something has the golden proportion. Think of Aristotle's dual path of scientific reasoning: generalizing from particular observations into a universal law, and then back from universal laws to prediction of particulars.
  • Point out how it is not accurate. Just superimpose the golden spiral and everything can be claimed to fit. But do they really? Look at the stairs of Parthenon. Look closer at the twitterscreencap, does the spiral really fit nicely??
  • Not all plants, art pieces, buildings or faces fit the golden ratio proportions. Yet many of these ‘non-golden’ persons and objects are beautiful to others, nonetheless. Is it merely a coincidence then?There are thousands of websites claiming the Golden Ratio pervades everything in nature, but rarely are there credible academic sources that agreeConclusion: The Fibonacci Sequence and The Golden Ratio are interesting mathematical concepts with unique aesthetic properties. BUT. There exists an overabundance of mystical thinking, speculation and fiction about them appearing in art, ancient architecture and nature.
  • Symmetry was already an aspect well understood by the Greeks, Romans and even through the Renaissance period, by which buildings were all constructed based on sheer symmetry
  • Many other studies replicate similar results
  • I’m sure you must be excited to see what a complete research has shown

    Defining Beauty
    what is beauty? what are the theories of beauty?
  • DEFINITION OF BEAUTY
    WHAT IS THE
    DEFINITION
    OF BEAUTY?
    “No particular
    definition”
  • DEFINITION OF BEAUTY
    Definitions for reference
    Beauty (according to Oxford Dictionary)Excelling in grace of form, charm of colouring, and other qualities, which delight the eye and call forth admiration: a) of the human face and figureb) of other objects
    Beauty is a basic pleasure
    Beauty can be something intrinsic to object (color, form, and other qualities )or simply the pleasure an object evokes

    Golden Ratio
    what is the golden proportion? why is it significant?
  • GOLDEN RATIO
    Ratio of the sum of the quantities to the larger quantity is equal to the ratio of the larger quantity to the smaller one
    Ancient Greek mathematicians first studied it because of its frequent appearance in geometry
    Irrational mathematical constant,
    • approximately 1.6180
    “Extreme and mean ratio" was the principal term used from the 3rd century BC until about the 18th century.
    Denoted by the Greek lowercase letter phi
  • GOLDEN RATIO
    “VISUAL DEFINITION”
  • GOLDEN RATIO
    Golden rectangle: side lengths are in golden ratio
    When a square section is removed, we find another golden rectangle. This pattern can be repeated infinitely.
    Corresponding corners of the squares form an infinite sequence of points on the golden spiral, the unique logarithmic spiral with this property.

    Symmetry
    symmetry as beauty? why is symmetry beautiful?
  • SYMMETRY BY GREEKS AND ROMANS
    Symmetry is the foundation for numerous Greek and Roman architecture, continuing into the Renaissance
    Victorian-style pillars
    Trevi Fountain (Renaissance)
    Pantheon of Rome (Roman Empire)
    Parthenon of Acropolis (Ancient Greece)
  • SYMMETRY: FACIAL SYMMETRY

  • SIR FRANCIS GALTON
    Sir Francis Galton (1811-1911)
    half-cousin of Charles’ Darwin
    Polymath, numerous contributions to many scientific fields such asmeteorology, psychology, criminology
    1876 - 1900: Composite Photography
    projecting face photographs of many different individuals onto a single piece of photographic film
    Galton’s colleagues noted that composites tended to be more attractive than the individual faces
  • COMPOSITE PHOTOGRAPHY
    Case for Eugenics
    • Eugenics: Nature NOT Nurture determines a person’s eventual character and personality
    • Identification of “typical criminal faces”
    Led to further studies of facial averageness!
  • FACIAL AVERAGENESS
    Study of Facial Averageness
    Numerous studies were conducted throughout the century BUT with advent of technology, greatly improved the studies
    1886: Stoddard
    1990: Psychologists Langlois and Roggman
    2005: Imaging Researcher Pierre Tourigny
    Computer algorithms revealed that symmetry plays a big role in human faces

  • DIFFERING INTEPRETATIONS
    (1) symmetric individuals are attractive because they are particularly healthy
    (2)averageness reflects optimal design of physical traits by nature
    human visual system favours processing symmetric than asymmetric stimuli

  • PROPORTIONALITY
    “What do we identify visuallyas human?”
    Studying of proportions really took off during the Renaissance
    Renaissance: the focus is back on HUMANS, THE HUMAN BODY
    Focus on aesthetics brought about numerous developments in the study of proportions that define humans
  • ANCIENT GREEKS AND ROMANS
  • MICHELANGELO
  • LEONARDO DA VINCI
  • FACIAL PROPORTIONALITY
    Renaissance Period
    Leonardo Da Vinci and Michelangelo did extensive studies concerning the proportions of human face
    Formed the basis of aesthetic knowledge on human faces
  • BODY PROPORTIONALITY
    Renaissance period
    Ideal height as having a head to body ratio of 1:8
    V-shaped torso
    Recent research
    Men: a waist-to-shoulder ratio of 0.75 or lower are viewed as considerably more attractive

    Evolutionary Beauty
    what is the impact of evolution on beauty?
  • Darwinian Theory of Beauty
    For nearly 2000 years, philosophers, artists and scientists have tried to explain beauty using mathematics.
    WHY?
    • Mathematical idea fits in a general way with platonic or religious ideas about origin of the world
    • BUT, Measurement systems have failed to turn up a beauty formula!
    • Another example how ideas of ancient philosophers have misguided later generations
    • Darwin’s evolution theory led toparadigm shift from an emphasis on mathematics to biology
  • EVOLUTIONARY PERSPECTIVE
    Darwin: Evolution of Beauty
    Natural Selection
    Evolution or co-evolution of peculiar features give advantage to an organism, increasing chance of survival and reproduction
    2) Sexual Selection
    Some physical qualities lure the other sex
    e.g. Peacock’s tail that not only doesn’t helpwith but impedes survivability
    Beauty is important in arousing and sustaining interest or even obsession to allow people to make decisions to enhance survival or reproduction
  • DARWINIAN APPROACH TO BEAUTY
    Beauty is nature’s way of acting at a distance
    Evolution’s trick is to make things beautiful, to make them exert a magnetism, and give one pleasuresimply by looking at them
    The experience of beauty is a component of a series of Darwinian adaptations
    Universality of our artistic and aesthetic taste can be explained by Darwinian theory of beauty
  • UNIVERSALITY OF BEAUTY
    Is beauty a universal concept?
    “Beauty lies in the eyes of the beholder?”
    How about culture and media influences?
  • UNIVERSALITY OF BEAUTY
    ACROSS AGE
    Even 3 month old infants prefer to gaze at faces that adults find beautiful, including faces from races they have not seen before
    7 year olds, 12 year olds, 17 year olds and adults do not differ significantly in their ratings of attractiveness of faces of children and adults
  • UNIVERSALITY OF BEAUTY
    ACROSS CULTURE
    Jones and Hill asked people from 5 cultures to rate a multiracial, multicultural set of faces
    2 isolated tribes, Hiwi and Ache Indians
    Russian
    Brazil
    United States
  • UNIVERSALITY OF BEAUTY
    People tend to agree which faces are beautiful and find similar features attractive across ethnically diverse faces
    All attracted to similar geometric proportions in the face
    Female faces with small lower faces (delicate jaws and relatively small chins) and eyes that were large in relation to the length of the face are preferred
  • UNIVERSALITY OF BEAUTY
    “Is beauty a universal concept?”
    Underlying universal mechanisms are responsible for beauty
    Beauty is an engineered manifestation
    Perception of beauty features may be governed by circuits shaped by natural selection in the human brain
  • UNIVERSALITY OF BEAUTY
    But people still seem to be largely agreeable and consistent in ratings of beauty
    People quote culture as being important BUT it still requires a basic premise that coheres with human intrinsic preferences of beauty and instinct
    “Beauty lies in the eyes of the beholder?”
    “How about culture and media influences?”

    Conclusion
    thoughts on the history and theories of beauty
  • CONCLUSION
    For thousands of years, philosophers, mathematicians and artists have tried to explain beauty using the language of mathematicsbut focus has been on details and intricacies
    Darwin’s evolution theory provides a big picture: Experience of beauty, with its emotional intensity and pleasure, belongs to our evolved human psychology
    Darwinian approach can be used to explain the universality and functionality of beauty
    The answer to questions pertaining to beauty may lie in cognitive neuroscience and biology
