Activity 2
The Golden Ratio
The Golden Ratio is a number that occurs in both mathematics and in nature. In this activity you will examine how this ratio occurs aesthetically, geometrically, and mathematically.
Your Favorite Rectangle
Examine the five rectangles drawn below from several different views. Choose the one rectangle that is most appealing to you and place an X on it. Use a metric ruler to measure both sides of each rectangle to the nearest millimeter. For each rectangle, divide the length of the longest side by the length of the shortest side and write this ratio on the rectangle. Which rectangle was the most liked in the entire class?_ What is its ratio?_
Beauty of the Body
The Golden Ratio can also be found in the dimensions of the human body. Measure your height to the nearest centimeter and record it below. Measure the distance of your navel from the floor to the nearest centimeter and record that also. Divide your height by your navel height to find the height/navel ratio rounded to two decimal places and record that below. Height = Navel Height = Ratio =
The Pentagram
The Golden Ratio also appears in the measurements of many common geometric figures. The common pentagram on the next page has the golden ratio hidden in its structure. This star is composed of a regular pentagon with an isosceles triangle on each side. Use a metric ruler to measure the lengths of the segments AB, AC, AD, and DC to the nearest millimeter. Divide to find the ratios of AB to AC; AC to AD; and AD to DC rounded to two decimal places.

Monday to Friday 11-15 March 2002 The Golden Ratio Leonardo Fibonacci was an Italian mathematician with a penchant for decimalization and rabbits! Having introduced the numbers to 9 to Europe (like some medieval Big Bird from Sesame Street), he turned his attention to a different series of numbers: The Fibonacci sequence is generated by adding the previous two numbers in the list together to form the next and so on and so on... Divide any number in the Fibonacci sequence by the one before it, for example 55/34, or 21/13, and the answer is always close to 1.61803. This is known as the Golden Ratio, and hence Fibonacci's Sequence is also called the Golden Sequence.

Science Human Body ... Help Like this page? Send it to a friend! Beauty Can beauty be measured? Right through history and across different cultures scientists and artists have tried to calculate the perfect dimensions for a beautiful face. Many "formulas" have been used in this attempt, the most famous of these being the Golden Ratio (Phi) , or Golden Proportion. This is a ratio of 1 to 1.618. The ancient Greeks were aware of this and used it in their art and architecture, and it was felt that this numerical association was so perfect and seen in so many places in the natural world, that it came close to the divine, and so these proportions are responsible for the uniformity of faces of thousands of statues and paintings throughout the history of western art. Click here to find out how to use the beauty mask Some cosmetic surgeons have even begun using the Golden Ratio as a guide for their work. Dr. Stephen Marquardt has discovered a 'Universal Beauty Mask' mathematically created from the Golden Ratio. In our programme he demonstrated that the grid-like mask 'fits' beautiful faces of all races and claims that most people (including babies) are naturally and instinctively drawn to faces that conform to the 1:1.618 Golden Ratio, and that we instinctively find them beautiful. Dr Marquardt also thinks that beauty is still in the eye of the beholder to some extent, because through our experience we may 'fine tune' our preferences. The faces of our loved ones and people we admire may become more beautiful to us over time, because of what they mean to us. However, he says, the Golden Ratio mask is the essence of facial beauty.

    Jeremy Zechar It is human fascination with the infinite that also leads us to perhaps the most "underrated" irrational number in mathematics: Phi. More commonly called the "Golden Ratio" or "Golden Section," Phi has a numeric value of approximately 1.618. Although not as well known as pi or e, this number can be found in architecture, art, and nature. Herein, we discover the magic of Phi. You are here :

    Mathematics in the Public Eye
    Film director Robert Zemeckis recently quipped that one of the fundamental commandments of Hollywood filmmaking is to eliminate numbers in a movie for fear that the audience will be confused. A handful of filmmakers, however, have disregarded this rule and actually made critically successful movies about math. Good Will Hunting , for example, tells the story of a blue collar Boston janitor who also happens to be a mathematical genius. Throughout the film, we see Matt Damon proving complex geometrical problems. In the independent film arena, Pi has been successful; here the protagonist is convinced that stock market patterns can be found in the Talmud and deep within the digits of the number pi.

    the golden ratio A simple knot made with a strip of paper, and then carefully flatted is a " golden knot " ; just fold over one of the strip's ends and you get a complete pentagram (convex regular pentagon with its five diagonals which are the sides of a regular star pentagon). The ratio of the sides of this two regular pentagons is the golden ratio j.
    A rectangle whose length/width ratio is the golden ratio is a golden rectangle . Its construction is simple (with AB=2AU, ABCD and ABC'D' are two golden rectangles, and we get the first by adding a square to the second).
    The pentagram shows several golden sections and several examples of the two types of golden triangles (isosceles triangles with ratio of the sides equal to j An ellipse inscribed in a golden rectangle is a golden ellipse (ratio of the axis equal to j
    j
    Its area is pj j With sequences of embedded golden rectangles or triangles, we get easily nice approximate drawings of the golden spiral
    As the other logarithmic spirals - also known as equiangle spirals or Bernouilli's spirals - they are invariant by similitude ; Miss Nature uses them to provide harmonious growths (shells, horns...). Golden rectangle, golden ellipse, pentagram, golden spiral... are generally considered as especially harmonious. It's not surprising that the golden ratio is widely used painting and in architecture.

    Golden Ratio

    A number often encountered when taking the ratios of distances in simple geometric figures such as the pentagram decagon and dodecagon . It is denoted , or sometimes (which is an abbreviation of the Greek "tome," meaning "to cut"). is also known as the divine proportion, golden mean, and golden section and is a Pisot-Vijayaraghavan constant . It has surprising connections with continued fractions and the Euclidean algorithm for computing the greatest common divisor of two integers Given a rectangle having sides in the ratio is defined such that partitioning the original rectangle into a square and new rectangle results in a new rectangle having sides with a ratio . Such a rectangle is called a golden rectangle , and successive points dividing a golden rectangle into squares lie on a logarithmic spiral . This figure is known as a whirling square . The legs of a golden triangle are in a golden ratio to its base and, in fact, this was the method used by Pythagoras to construct From the definition of the golden mean combined with the above figure

    Didrik Wold MAT100C – Gruppe 20 Essay The Golden Ratio The Golden Ratio ( and related names and properties: phi ratio, sacred cut, golden mean, divine proportion, golden number, golden section) If we let 1 be the shorter part of the segment and x be the longer part and the whole segment be the sum (1+x) then we have the following equation: 1/x = x/(x+1) (Side note) This has some interesting results if we expand on it a bit. From this we can see also that: The solution of this equation is sqrt(5))/2 It is important to include Fibonacci numbers and the Fibonacci series in any discussion about the Golden Ratio. The original problem Fibonacci was working with was trying to find out how fast rabbits could breed in ideal circumstances. But that’s not what we’re interested in. We’re interested in the resulting series of numbers. This series is made up of numbers in such a way that each number is the sum of the two numbers before it. This is closely related to the Golden Ratio because if you take the ratio of two successive numbers in Fibonacci's series divide each by the number before it, we will find the following series of numbers: It becomes fairly clear what is happening once we plot the ratios on a graph: The Fibonacci numbers can also be used to create what are known as a Fibonacci rectangle and spiral. These are similar to the Golden Rectangle and Spiral (which are discussed next) but different in some important ways.

    Doctor May Have Beauty's Number By Rafe Jones Ever think a number could be beautiful? From the bad luck of 13 to the holiness of 3, people have long ascribed mystical and abstract properties to numbers. One number in particular has been associated with beauty for nearly 2,000 years, and it's not a number you can count to: the so-called "golden section" is an irrational number approximately equal to 0.618. Dr. Stephen Marquardt, a former plastic surgeon, has used the golden section and some of its relatives to make a mask that he claims is the most beautiful shape a human face can have. Beauty Theory According to Dr. Marquardt, beauty is a mechanism to ensure humans recognize and are attracted to other humans. "Other animals recognize members of their own species and have a tremendous reaction when they do," he says, noting dogs' common reaction to other dogs. He adds that humans are highly visual creatures, so we use sight as our primary means of recognition. The most beautiful faces, he claims, are the ones that are the most easily recognizable as human. "Beauty is really just humanness," he says. Dr. Marquardt theorizes that we discern whether a face is obviously human by unconsciously comparing it to an ideal face that lurks in the unreachable recesses of the psyche. Since we have no direct access to this ideal "most human" face, we can't say precisely what it is; however, Dr. Marquardt claims he has captured the ideal face in his beauty mask. He says, "The mask radiates, it advertises and screams: 'human, human, human.' "
