The golden section is a ratio defined by the Phi number. It appears in the proportions of the human body, as well as in great works of art (The Last Supper), architecture (Parthenon) as well as in nature (maple leaves). The golden section has been used in arts since the Renaissance and this section makes a harmony between symmetry and asymmetry. The famous Mona Lisa, painted by Leonardo da Vinci, is made on golden squares.

I found it interesting that this section is present in Mathematics too, and has an approximately value: 1.61.This means that if we have two values a and b (a>b) the sum of these is to a as a is to b. The architects considered that the golden section gives the most aesthetically pleasing proportion. They are present in the Giza Pyramids and Parthenon facade too.

The activities that I would prefer would include meeting other teachers. This way we’d have the chance to get to know each other’s cultures and lifestyles! I would like to try any kind of activities related to the golden section, because I find it really interesting. I would like to do researches referring to the topic of the project, to take part in group researches, in different group activities and of course, exchange of experience with teachers from other countries.

I am interested in the topic of the golden ratio and it’s significance in all of the disciplines that are closely related to it, so I would like to study more accurately this topic.
