Fractal

Fractals and stars are two of the most beautiful and complicated-looking classes of geometric objects out there. We're going to explore these objects and how to carve them on a pumpkin. Unlike the last one on carving polyhedral pumpkins, where we used the entire pumpkin to car ...more

Natural processes often create objects that have a fractal quality. Fractal branching patterns occur in plants, blood vessel networks, rivers, fault lines, and in several electrical phenomena. Many of these processes take lifetimes, or even occur on geological timescales. But ...more

One of the best things about talking to other people who love food is that they point you to weirdly beautiful ingredients, like this: No, that's not an escapee from Middle Earth you're seeing. It's one of Mother Nature's best attempts at making fractals come alive into a gold ...more

Last post, we looked at fractal cookies based off of the recipe by Evil Mad Scientist Laboratories. In this post, we'll follow their recipe for fractal cupcakes based off of the Koch Snowflake, which we used previously to decorate pumpkins for Halloween. This past Sunday, I d ...more

After I made a blog and sent it to my friends about how I made Gingerbreadman Map fractal holiday cookies, one of them linked me back to the Sierpinski Carpet cookies, which I loved! So, I thought I'd share my how-to with everyone as well!

I'm sure many of you have already seen this, but being Halloween and mathematically inspired, I thought I'd dig up an old favorite for those who may have missed it. Original post with quote from Cyriak here. More fractal hands: Tim Hawkinson's "Fruit" Series

Following the pattern of fractal goodies, I found this great article on making a giant fractal pecan pie. Seems like you'll need some dedicated pecan pie enthusiasts (shouldn't be hard to find) to help you out!

What is fractal? Well, it's a geometric shape which sometimes is hard to draw but looks very nice. There are some fractals which are easy to draw for example Koch snowflake or Sierpinski triangle: Drawing Koch Snowflake: Draw a equilateral triangle (every side is equal) On e ...more

Curve stitching is a form of string art where smooth curves are created through the use of straight lines. It is taught in many Junior High and High School art classes. I discovered it when my math students started showing me the geometric art they had created. The process of ...more

It's Monday, which means once again, it's time to highlight some of the most recent community submissions posted to the Math Craft corkboard. I also thought we'd take a look at building a sliceform model of a hyperbolic paraboloid. Rachel Mansur put up two posts on her Modula ...more

Halloween is coming up, so many of you may have a need or desire to carve a pumpkin and turn it into a Jack O' Lantern. This week we are going to explore carving our pumpkins into interesting geometric shapes. In this post, we will carve the pumpkins into spherical versions of ...more

In 2008, Audiosurf came out on Steam, creating the psychedelic music game genre. If you haven't played it in the intervening three years, you're missing out on one of the coolest things in video games. The player selects any MP3 on their computer, then the game builds a unique ...more

Welcome to WonderHowTo's first Weekly Community Roundup! Each week we will be featuring the best projects from the community, as well as ongoing challenges and activities you can partake in. WonderHowTo is made up niche communities called Worlds, so if you've yet to join one, ...more

This three dimensional Sierpinski tetrahedral structure was created with a lot of help from my Year 10, 12 and 13 classes. It is inspired by the Sierpinski triangle fractal. Our challenge was to take this design into three dimensions and create a fractal Christmas tree. We st ...more

It's Monday, time to highlight some of the community submissions posted to the Math Craft corkboard. One of these posts inspired me so much, I think it merits a closer look. Today, I present a "simple" method for making a golden spiral using just a straight edge, a compass, an ...more

It's another Monday, which means it's once again time to highlight some of the recent community submissions posted to the Math Craft corkboard. Additionally, I thought we'd take a look at the process of stellation and make some stellated polyhedra out of paper.Rachel Mansur of ...more

Since it is now the holiday season, I thought we could spend this weekend making some baked goods that have mathematical patterns on them. In this post, we'll look at making cookies that have a fractal pattern based off of a modification of the pixel cookie technique. The peo ...more

It's Monday, and once again it's time to highlight some of the community submissions posted to the Math Craft corkboard. In addition, I thought we'd take a look at having fun with the geometrical properties of polygons and circles by using one of the best circles I know, the p ...more

It's Monday, which means once again, it's time to highlight some of the recent community submissions posted to the Math Craft corkboard. In this post, we'll also make a flexagon, which is a type of transformable object. Rachel Mansur of Giveaway Tuesdays posted several pictur ...more

It's no secret that cauliflower is good for you—but not nearly enough people know that the best part about cauliflower is its insane versatility. Because its cooked flavor is so mild, it can be incorporated into a crazy amount of dishes and preparations. So whether you're try ...more

Create Your Cardboard Masterpiece Before you can create the shader, you must create an object to test the shader out on so that you will feel comfortable with your results. I have chosen to do the traditional cardboard box for this. Create a New Shader Now select the region ...more

If you take two flat mirrors and place them front to back and look at them, you can see an infinite number of reflections. While this is a self-replicating pattern and can be somewhat mesmerizing, it isn't anywhere as interesting as looking at the chaotic scattering of light t ...more

Did you ever, as a know-nothing kid, push against your closed eyelids for the pleasure of the resultant light show? LCD bending takes the low-tech fun of physical retinal stimulation and updates it for the 21st century. And, as the title suggests, the end result looks very muc ...more

I entered the 2009 Crash the Superbowl Contest with this entry. It was a tremendous amount of fun to make. The fractal dorito was made from about 75 lbs worth of tortilla chips (about 12000 chips total) and was 64 ft on a side.

Combine a bunch of fractal objects with mirrors and and lights and the ability to walk around inside and you get something like the image below. For more information on the exhibit as well as several more pictures and a video check out this article.

For someone who loves math as much as Vi Hart (a self-proclaimed "mathematical musician"), she doesn't pay an awful lot of attention to her math teacher. But that's ok. Cuz somehow her wonderfully whimsical doodling transforms into mini lessons on graph theory, mobius strips, ...more
