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.

The Golden Ratio (@Luckyrockz2)

The Golden Ration lesson really got me thinking about maths and the ways it has been developed into what it is today. I really enjoyed the lesson and hope that we explore many more interesting phenomena.

Beauty & Mathematics continued (25 July 2014)

Hello class! Apologies that I can’t be there with you today – but you have some very interesting material to cover today nonetheless.

VIDEO 1: Donald Duck in Mathmagic Land

This video is quite long (about 27 minutes) and covers a wide range of topics. As you watch it, take notes on the following:

  • What mathematical ideas are presented?
  • Select two that interest you in particular and research them further. How do they relate to the mathematics you already know? Where else in the world do these concepts reappear?

You may take notes on your laptop, but you will definitely need to have a pen and paper available anyway as most of the concepts addressed in the video are visual and you will need to illustrate them in some way. Now that you know what you’re looking for, here’s the video:

After the video is finished, take 15 minutes to look over the notes you have taken and reflect on them as usual. (You should use the questions I wrote about in this post to guide your thoughts.)

VIDEO 2: TedXEast – Matthew Cross

The next video you watch is a TED talk. Again, take some brief notes (but be aware that the presenter goes through the material very quickly). Similar to before, select the two most surprising examples that he talks about and briefly describe why you think these are so unusual. Here’s the video:

VIDEO 3: How to measure beauty

Here’s the last video you’ll be watching. As you watch it, you simply need to answer this question: “Is human beauty just about numbers? Why or why not?” Answer in some detail and try to justify your response with evidence and examples.

As usual, please compose your thoughts in a post and email it to me. Some of you have kept on top of each lesson’s assigned tasks, but others of you are slipping behind – use this opportunity to catch up! (And don’t forget to carefully follow the instructions I gave you in the very first lesson.)

See you again next week!

Phi (by @T_of_the_P)

Yesterdays lesson, I found, really made so much sence, yet so little sense. I’m REALLY interested in this golden ration, phi, which I had never heard of before but I’m intrigued by it’s ‘mysteries’. Especially with all of those structures and cards. I think is topic is going to extremely fascinating and it will be cool to see all these small links in maths which somehow line up to come up with something so unlikely, yet so true. I’m interested to see what we will be learning tomorrow.
