Beauty What do 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).

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)

11
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 Fibonacci Sequence the first 20
0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144,
233, 377, 610, 987, 1597, 2584, 4181, 6765.
15
Where did 1.6180339887. come from?
Lets look at the ratio of each number in The
Fibonacci sequence to the one before it
16
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
persons face is about 11/2 times longer than it
is wide.

The Golden Ratio Some Other Examples
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 is 34
and the number of spirals curving right is 55.

Mathematics and Architecture
In ancient times architecture was a field of
mathematics. Architects were simply
mathematicians that someone would hire. 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 beauty-
Mathematics in nature and architecture in
construction.

Mathematics and Architecture
The tallest building in the world The Burj
Khalifa in Dubai. Very tall buildings are in
danger of many things depending on where they
are. Stability against earthquakes is important
as well as ensuring aerodynamic designing is done
perfectly to mitigate against swaying.
25
Mathematics and Architecture
Some are purely utilitarian such as the Great
Wall of China.

    and wonder.

Numerology
It has always been, and still is 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 ones 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 Ina Brown, the vowels are
eae ia o 5 1 5 9 1 6 27 9 So this
persons soul urge number is 9 and they can go
read up about their personality.

Numbers are to mathematics what words are to
language. To the distress of the general
society mathematicians have dreamt up types of
numbers.
