### Re: The Golden Ratio (@tdawgg_99)

It is hard to believe that such a mathematical concept even exists. I for one had not clue what this dealt with until today, after watching the video. What makes it perplex yet at the same time highly interesting and remarkable is how the golden ratio can be applied to form such complex shapes, i.e. spiral and what all can be formed within it.

### Video Lesson (by @happynikitakk)

:O- My reaction to today’s lesson. WOW! Math really is everywhere! The first two videos we watched today- Donald Duck in Mathmagic Land and the TED talk, made me realise that math exists in everything-in galaxies, like our Milky Way, music, plants, animals, as well as in architecture and paintings. Even the proportions of our bodies are built upon the universal Golden Ratio. So much that, you could almost say that maths IS everything.

The question- is human beauty just about numbers?- intrigued me. However, I believe that “beauty lies in the eye of the beholder.” My concept of beauty, runs beyond physical appearance, but lies in personality and human nature. I believe it is our small imperfections and differences show true beauty.

Donald Duck Video

I never knew there was mathematics behind music, that octaves had an equation behind it.And the introduction of the golden ratio being Nature’s perfect ratio was really surprising, how shells, flowers and leafs had the golden ratio being responsible for their very existence.

Ted Talk: Golden Ratio

One of the most intruiging topics he raised was that Apple’s logo is the result of the golden rectangle. To think that the perfect shape of an apple had a concept like that. Another one was the design of a pinecone which was also due to the golden ratio.

Human Beauty

Human beauty is just about numbers(i think), as it has to deal with the ultimate ratio of all time. This brings a whole another meaning to ‘natural beauty’. GETTIT, golden ratio is Nature’s perfect ratio. XD

### the golden ratio (by@subaruau)

it is very interesting that such a ratio can create a shape as diverse as spiral and that all the shapes can be formed by it

thing i found interesting about the golden ration:

1) music was discovered by pythagoras using the golden ratio

2) maths in the form of the golden ratio is present in everything

3) people can use the golden ratio to train for races (marathons)

4) the pentagram is the embodiment of the golden ratio in infiniteness (if that is a word)

overall i found this lesson intriguing and it made me think throughout.

it was all in all a very educational lesson for me

P.S. this is Raphael

### Beauty and Mathematics Videos (by @brendanmckee99)

Today I found some of the ideas explored in the videos quite interesting.

In the first video the ideas that were included were how maths is related to music, nature and games, often relating to the golden ratio. I found it quite interesting that pentagrams contained the golden ration many times within them, and how it even divides some lengths up further into the golden ratio. I also liked how something that is half the length of another produces a sound one octave higher, and hence a quarter two octaves and so on.

In the second video I found it surprising that the golden ratio and spiral is often used in website design, which makes sense to appeal to users. I also found it interesting that the golden ratio can be found in our DNA, and is also linked to energy transfer in the universe, which is why it is found in waves, hurricanes, patterns of particles and galaxy arms.

For the third video I had to answer ‘Is human beauty just about numbers? Why or why not?’. I don’t believe that human beauty is just about numbers. This is because that physical beauty cannot simply be based off numbers, specifically the golden ratio. Even if someone is made in ‘perfect’ proportions, they may not appeal to everyone. Additionally, beauty is not just physical. True beauty in people involves non-physical concepts such as personality and intelligence. Therefore human beauty is not just about numbers.

### The Golden Ratio (by @LWM_Vincent)

The golden ratio is everywhere and is quite confusing.

I learnt the golden ratio in general. It’s a very interesting concept of everything. I also know what ‘phi’ is, confusing yet used everywhere.
