MATHEMATICS DURING THE MEDIEVAL PERIOD

MATHEMATICS IN RELIGION

• Geometry is used in the developments of some religious designs used during that time which some are even used until today. By infusing Mathematics, their works of art became full of symbolisms and meanings. During Medieval times, people use different geometric symbols to defy their religious ideas and beliefs as much as words do.

The Quadrivium

Arithmetic (Number in itself) - as such number is a pure abstraction outside of time and space. This aspect of the Quadrivium deals with the different characteristics of each number

The Quadrivium

Geometry (Number in space) - specific shapes can have a deeper meaning. This aspect relates symbolism and it is frequently used in architecture

Geometry

Inspired by the 13 books of Euclid’s Elements

The Quadrivium

Music (Number in time) - covers music in general and particularly the topic of natural harmonics

Golden Ratio

• two quantities are in the golden ratio if their ratio is the same as the ratio of their sum to the larger of the two quantities.

The QuadriviumAstronomy (Number in time and space) - covers the movement of planets in space and the natural harmonics between the planets when looking at the aspect of time (harmony of the spheres). This is the first time aspects of time and space meet with the abstraction of number thus it builds the foundation for science

Astronomy• During the medieval period, scientists in

the Islamic world made many contributions to the field of astronomy. While their work was based on ancient sources from Greece, Iran, and India, they updated methods for measuring and calculating the movement of heavenly bodies, and continued to develop models of the universe and the movements of the planets within it.

ART“Without Mathematics, there is no art.”

– Luca Pacioli

Take a look at the Fibonacci Sequence…

1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89…

Try getting the ratio between one of the numbers and the number before

it.

Inspiration Comes (Fibonacci)

by Jim T. Henriksen

Inspiration Comes (Fibonacci)by Jim T. Henriksen

Iam

sittingquietly,

listening for thequiet noises in the darkness,

ghostly images flying between the tall pine trees,illusion created by the mind, made by shadows, the

brain playing tricks on itself.

It sits there, the raven, black as night, looking at me with its dark eyes in the dark night. Inspiration comes. Words form in my head. Nevermore.
