THE BEAUTY AND REALITY OF MATHEMATICS HEARTFELT THANKS TO THOSE BEFORE US…… WITH US NOW…………AND TO COME ALL THE GIFTS HAVE MADE LIFE BETTER The Greek s The Sumerians The The Chinese The Indians The Arabs Beauty: What we define it to be? The quality present in a thing or person that gives intense pleasure or deep satisfaction to the mind, whether arising from sensory manifestations (as shape, colour, sound, etc.), a meaningful design or pattern, or something else (as a personality in which high spiritual qualities are manifest) Chaos Theory Fractals – the delight of Chaos Theory A fractal expression looks like Z = Fn1(Z); Z = Z*Z + Fn2(C) Mathematics and Physical Beauty Mathematics and Physical Beauty Leonardo da Vinci's drawings of the human body emphasised its proportion The ratio of the following distances is the Golden Ratio: (foot to navel) : (navel to head) Mathematicians – believe it or not, we are human! Galois Nash Noether Newton Germain Gauss Einstein Green Mathematicians – our minds Mathematicians – our mind Mathematicians – our minds Numbers are to mathematics what words are to language To the ‘distress’ of the general society mathematicians have ‘dreamt’ up numbers The first securely datable Mathematical Table in World History, circa 2600 BCE was developed by the Ye Gads!!! Algebra!!! THE DISTRIBUTIVE PROPERTY y x z x+4 (x+4)5 x (x+4)x Area = (x+4)(5+x) = (x+4)5 +(x+4)x = 5x+20+x2+4x = x2+9x+20 Perfect-Square Trinomials a b a b a2 ab ab b2 You can see from the diagram that the area of the large square is both (a+b)2 and a2 +2ab+b2 Completing the Square Incomplete squareCompleted square x x2 x x2 6x 6x 6x x2 +12x x2 +12x +62 ?? 6x 62 RESOURCES TO TEACH MATHEMATICS WHY ARE WE DOING ALL OF THIS? WHERE DO WE GO FROM HERE? [...].. .Mathematics and Physical Beauty  Why do we find people to be attractive?  Because the proportions of the length of the nose, the position of the eyes and the length of the chin all conform to some aspect of the Golden Ratio The Golden Ratio The Fibonacci Sequence: the first 20 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377,... Geometry is the guiding principle between the two areas Mathematics, however, is indispensible to the understanding of structural concepts and calculations Mathematics and Architecture Both areas search for order and beautyMathematics in nature and architecture in Mathematics and Architecture The tallest building in the world: The Burj Khalifa in Dubai Very tall buildings are in danger of many things... In seed heads such as the sunflower shown here and the coneflower previously, spirals curve left and right The number of spirals curving left and the number of spirals curving right are neighbours in the Fibonacci sequence, for example, the number of spirals curving left Mathematics and Architecture In ancient times architecture was a field of mathematics Architects were simply mathematicians that someone... Let’s look at the ratio of each number in The Fibonacci sequence to the one before it: The Golden Ratio Measure the length and width of your face Divide the length by the width This should give approximately 1.6, which means a beautiful person’s face is about 11/2 times longer than it is wide The Golden Ratio: Some Other Examples The Golden Ratio: Some Other Examples The Golden Ratio: Some Other Examples... things depending on where they are Stability against earthquakes is important as well as ensuring Mathematics and Architecture Some are purely utilitarian such as the Great Wall of China Mathematics and Architecture Some failed miserably and provide us with mirth and wonder Mathematics and Architecture  The Alhambra Palace in Andalucia, Spain  Building 1238 Watch started in Mathematics and Architecture... = 3 Example: Heather Ina Brown, the vowels are eae ia o 5 + 1 + 5 + 9 + 1 + 6 = 27 = 9 Mathematicians – believe it or not, we are human! Galois Nash Noether Newton Germain Gauss Einstein Green Mathematicians – our minds Mathematicians – our mind Mathematicians – our minds Numbers are to mathematics what words are to language To the ‘distress’ of the general society mathematicians have ‘dreamt’ up ... the desire to understand people and ourselves Numbers were used a very long time ago, in the absence of more scientific means, to tell of one’s personality and future In this example we look at calculating the Soul Urge Number Write out your full birth name (this includes your middle name (s) Using only the vowels in your name, assign these values: A = 1, E = 5, I = 9, O = 6 and U = 3 Example: Heather
