Experience the union between Math & Art in a RAFT workshop!


While Geometry often describes and measures shapes like a cone, sphere or triangle, does it define the shape of a cloud, a mountain, a coastline, or a tree?

Starfish and Broccoli
are a few examples of fractal patterns in nature!
It does! Most patterns in nature, called “fractals” describe curves, surfaces and objects that have some very peculiar properties so irregular and fragmented, that it takes more than spheres, cones, circles, triangles, smooth or straight lines to describe them!

These fractals might resemble arteries, coral, a heart, a brain, tree branches and other such ‘designs’ that have symmetry, ‘self-similarity’ and are scale-free!
Fern fractals - with symmetry
and self -similarity!

 Look around you – Fractals are everywhere!  Have fun with us and discover everyday Fractals at the upcoming RAFT workshop ‘Fractals and Beyond’ on Feb 9th, at RAFT San Jose. This workshop will demonstrate how fractals can be related to Sierpinski's gasket, to patterns, to equations, to graphing, and to even a broccoli! 

Break off a branch of the whole broccoli and what do you see?  The smaller branch looks just like a miniature copy of the whole broccoli!  Now think of self-similarity in ferns, the formation of shells, mountains, lightening, river estuaries, fault patterns, galaxies, musical compositions, and other nature’s designs. 

A fractal’s dimension indicates its degree of detail, or crinkliness.  Simple curves, such as lines, have one dimension.  Squares, rectangles, circles, polygons and others have two dimensions, while solid objects such as cubes, spheres, and other polyhedra have three dimensions. 

All those dimensions are integers: 1, 2, 3… But a fractal could have a non-integer dimension of 1.4332.   By understanding fractal dimension, mathematicians can now measure shapes such as coastlines that once were thought to be immeasurable.

If you want to explore the world of Fractals, a science that marries Art with Math, join us for the upcoming workshop this week.

Science fairs: Nurturing the 21st century thinker

3D Tessellation model A bespectacled 6th grader enthusiastically explains ‘efficiency of 3D space tessellations’ with myriad equations and handmade tessellation patterns to address the needs of the packaging, storing, shipping and construction industry. Another middle school student, was inspired by his little brother’s telescope and built a simple vacuum chamber using a PVC pipe with a microphone and a speaker on both ends to find out how sound travels on Mars! This 8th grader from Granada Islamic School used an oscilloscope his mother found at an auction to measure the sounds. “I poke around and find junk to build my projects. It’s fun.” Science projects today have become fun for many students as they use more hands on activities to experiment and understand concepts. These two middle school students were among 996 participants at the recent Synopsys Silicon Valley Science and Technology Championship , where RAFT was one of the special judges.

How does math relate to real life?

By Jeanne Lazzarini, Math Master Educator/R&D Specialist, RAFT How does math relate to real life?   One way is to take a look at the shape of a cloud, a mountain, a coastline, or a tree!   You might be surprised to find that many patterns in nature, called fractals, including growth patterns, have very peculiar mathematical properties ---   even though these natural shapes are not perfect spheres, circles, cones, triangles, or even straight lines!  3D Fractals For Inspiration   So, what is a fractal?   Benoit Mandelbrot (November 20, 1924 – October 14, 2010) is commonly called the father of fractals. He created the term “fractal” to describe curves, surfaces and objects that have some very peculiar properties. A fractal is a geometric shape which is both self-similar and has fractional dimension.    Daydreaming fractals Ok, so what does that mean?   Well, “self-similar” means that when you magnify an object, each of...
