### Fractals (David Yoo)

Fractals are never ending, goes on forever, until the human eyes can’t see it anymore. it is one of the most beautiful type of shape that I have ever seen. Fractals can be enlarged and enlarged, part of it still resembling the original shape. Although it sounds unreal and magical, it exists all around us, like the coastline, fern leaves, rivers and tree branches. All of these are wonderful and awesome, but my favorite has got to be the Koch Fractals.

Favorite Fractal

The Koch Fractal is so simple to draw but extremely complex to our eyes. Its hexagons continue on spreading. it is extremely intriguing to our eyes, as all the fractals are. However, what makes this different to others, to me, is the fact that it resembles snowflakes. it shows the beauty of snowflakes, crafted in precise conditions in order to make such beautiful and intricate shape.

### The Golden Ratio in nature and architecture – David Yoo

These are the architectures and beings of nature that have become my favorite Golden Ratios.

Golden Ratio in Architecture:

1) Parthenon

The Parthenon in Greece follow the golden ratio in different parts of its structure. The entire front face of the Parthenon closely resembles the golden rectangle. Also, the structural beam on top of the supporting poles are proportional to each other, in golden ratio.

2) Notre Dame

Notre Dame in Paris, which was built in between 1163 and 1250 appears to have golden ratio proportions in a number of its key proportions of design. Although it is inaccurate to measure by a photographic source, it is possible to notice the golden ration implanted into the structure in various places.

3)Toronto’s CN Tower

The Toronto’s CN Tower, although modern, contains the golden ratio in its design. the ratio of observation deck at 342 meters to the total height of 553.33 is 0.618 or phi, the reciprocal of phi.

Golden Ratio in nature

The Fibonacci Sequence or Series has a relatioship to the Golden Ratio. The Fibonacci Series shows up in the number of leaves on a plant and The Fibonaccie Wequence or Series has a relationship to the Golden Ratio.

1)The Shell

Shells are the results of a famous shape made utilizing the Golden Ratio called Golden Spirals. The Shells closely resemble this shape as seen in this picture.

### Working out irregular areas

What strategies can we use to find out the area of the top playground? What information will we need?

### Fractals (Alex Ho)

Fractals in Nature

Fractals are everywherein nature, never ending, only as far as our eyes can see. Rivers, with theirwinding channels and weird small side ones, all relatively follow the shape asthe big one, as seen in the diagram shown in class, where taking a closer lookon the small ones, show a similar shape to the main. In a video shown, therewas conclusively no way to measure the coastline, simply because having smallermeasuring equipment yield different results from larger ones. Fractals are usedto describe this coastline paradox, making it impossible to accurately measurethe actual length.

Favourite Fractal

My favourite fractal would have to be in trees. I find treesintriguing, just spending time to watch them sway to the wind as well as wonderhow each branch is capable to grow from the trunk, and have further branches.The leaves too, seeing the patterns on them, and being able to hold ontobranches and then just fall off.

### The Essence of Fractals (Josh Luong)

Where are Fractals in Nature?

Fractals are pretty

much just an infinite and never ending pattern where the shapes created never

end but finding one in nature may not be as hard as you think. Fractals can be

seen almost everywhere in our environment such as shorelines where they keep

splitting up into various individual rivers and the dividing branches on trees.

It’s quite intriguing how these natural occurrences can bear such a breath

taking form where it seems to be never ending.

Which Fractal is my

favourite?

Being exposed to many

fractals on Google images, it’s a tough choice to eliminate the rest and only

choose 1, however if I had to choose a fractal that I could spend my whole life

with it and it only, it would have to be the Romanesco

broccoli. It may not look like the most colourful fractal however it’s edible.

An edible fractal is all I need to make my life complete. With every mouthful

of this broccoli, its like you are consuming infinity and with that reasoning,

I don’t think any other fractal could ever be contested with the Romanesco

broccoli.

### Symmetry and Tessellation (Josh Luong)

Today in class we

learnt about the properties of symmetry where we tested different methods such

as rotation, reflectional, scale symmetry and translational symmetry. Before

the lesson I had only known 2 of the 4 kinds of symmetry, which were rotational

and reflectional and my knowledge for shapes was expanded. It was amazing to

see and create the scale symmetry with my own shape, which could be made

smaller or bigger depending on the scale chosen on my ruler. This only makes me

think and wonder about the unique things that shapes may have other than

symmetry and tessellation.
