### Iterated Function Systems (@kewalbro)

Posted on

This lesson was a bit confusing but the graph at the end of the equation was awesome!!!

In this lesson, we learned about iterated function systems, which mainly involved fractals. The sequencing really got me confused but at end I understood it all. The function part and rule section, we did today was very interesting.The fractal graph was a new concept learned, however, the imaginary numbers and real numbers were quite confusing.

Today was a great day as it end with MATH

### Donald Duck and other amazing videos (@kewalbro)

Posted on

The videos were both funny and interesting as we got to learn a lot from it.

For the first video, Donald Duck in Mathmagic Land, ideas that surprised me were mostly about the golden ratio. It was how Pythagorus theorem is related to the music today and some sports that we play football. All of these ideas in the video are mathematical as it is all related to the golden rectangle/ratio.

For the second video, Ted talk, was again about Golden Ratio (man Golden Ratio are very interesting). The most surprising examples that was spoken was nearly everything in our life is based on the golden ratio. Also, when I saw that plastic surgery uses the golden ratio, I was shocked. These two examples are unusual because we never see them in right way or feel very little things in our lives.

For the last video, I think human beauty is not only about numbers, because sometimes when people have really beautiful face, doesn’t mean they are kind and grateful inside. It doesn’t matter if a person looks beautiful but unless they clean inside (numbers cannot prove this), for us their is nothing good in them.

### Phi and the golden triangle (by subaruau)

Posted on

i personally found the fact that most monuments in the world required the golden ratio.

i looked up many pictures and could locate many of the golden ratio including curved shapes. i found this lesson’s excercise very intriguing and informative. i feel as if the complicated pattern which it represents very intriguing like the rest of the lesson and the way spirals can be derived from a rectangular shape

P.S this post is late I got it mixed up with another

### Iterated Function Systems- Todays Lesson

Posted on

In this lesson, we learnt about the specifics of iterated function systems, mainly involving fractals. The sequencing really got me thinking more about how each function corresponds to one another and how they each link with a rule applied to it. Where there was an unbounding sequence, there was also a bounding sequence to go along with it and how they relate to each other. The fractal graph was a highly interesting concept learned, however, the imaginary numbers and real numbers were quite perplexing.

Todays lesson on Iterated Function Systems really got me thinking about how fractals work! And the graphical represenation of the unreal numbers looked pretty sick but was very hard to draw up on a cartesian plane. The exercise which got us to make sequances, that made either a bounded or unbounded sequence was very fun to play around with. I really enjoyed trying to find a bounded sequence as it was a challenge and made me experiment with many different numbers.

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.

### Cartography and Fractals(by subaruau)

Posted on Updated on

i found fractals very interesting as it seems infinte and that there were many ways to apply the fractals.

i found the lesson on cartography just as interesting as the ones on fractals and i enjoyed the practical activity and it was a challenge and it made me appreciate the intricacies of map making.

i also found the lesson on iterated function systems and the imaginary plane interesting and very informative

### The pizza slice that changed everything

Posted on

Sometimes it’s the little things that really make a difference.

It’s been a year of big changes for me. Many of those changes have been deeply and personally challenging, and I’ve lost count of the number of days when I’ve laid my head down on my pillow at night  in an exhausted state and wondered what on earth I was thinking when I took up this new role!

At that point in time, I call a variety of things to mind to rationalise for myself and make me feel a little better after a long and trying day. This week, one of the things I called to mind was a slice of pizza.

Context will help. One of the most novel experiences for me this year is being genuinely disliked. I have a feeling this is going to come across the wrong way, but most of the people I’ve interacted with in the past like me (or are very good at fooling me into thinking that they like me). For better or worse, I’m used to being fairly well regarded by those around me – and I’ve tried my best to give people good reasons to do that.

So this year it was a bit like jumping into a pool of ice water to have people – lots of them – really, honestly, openly, not like me. At first, like ice water, it was a raw shock to the system – was it going to get any better? But as time passed, I realised that there was no quick fix. I’d just have to get comfortable in the cold. Even though I didn’t like it, I understood very well why I was being treated this way – I was alien and unfamiliar to the school, not to mention inexperienced and making mistakes that had a flow-on effect to lots of other people. Well, fair enough then. Don’t expect to be liked – it’s not part of the role description.

But enter a group of year 12 boys who had their lunchtime hang-out spot in front of my classroom. One or two of them were in my class, but most of them I just got to interact with when I bumped into them in between classes. And frankly, whether intentionally or not, these boys just welcomed me. No matter what was happening, they would always greet me with a smile and chat with me as if they’d known me for years.

Friday was their last day of school before the HSC trial exams begin, and I had just wished my own year 12 class good luck for their assessments. The lunch bell rang and as everyone filed out of the room, I set about packing up all my things (whiteboard markers, worksheets, tripod, microphone)… only to be surprised by one of the aforementioned year 12 boys entering the room. “Sir, do you want some pizza?”

Some of them had gone and ordered pizza as a kind of pre-emptive celebration, I guess. The reasons for the food aren’t all that important to me, really. I was just touched that they invited me – a teacher, and a teacher who has just turned up at their school this year – to share some food with them. It was completely unrequested kindness – the very best kind.

Have you ever received a “slice of pizza” (or other unexpected gift) from a student?
