Number Theory

A few months ago I was commisioned by my brother and his fiance to create a math related baby item for two of their good friends who will become new parents at the end of January.  Combining two things I really love -- sewing and math -- was so much fun!  I gave them a couple of options to choose from, hoping of course that they would choose my favorite.  And they did!  I was going to make a ring stacker.  You know, like the plastic ones at the store except this would be made of fabric and would have mathematical constants appliqued on it.  It took a month to decide on sizes, get the pattern pieces made, and create the prototype.

But finally . . . it's completed!

The constants

For those of you who don't know:
i = squareroot of -1 (imaginary numbers)
phi = the Golden Ratio (Google it - there's lots of cool info. about this constant!)
e = exponential growth constant
pi = circumference of a circle divided by its diameter (we all love pi!)
infinity = infinity

The approximated values of said contants

The inside tube is also a rattle.

And because I just couldn't help myself, I also made some onesies for the new little one.  They are incremental in size, starting with 0-3 mo. all the way up to 12 mo. 

Thank you Philip and Jes for asking me to do this. 
It was so much fun!
I hope J and J's new baby will be happy, healthy, and (most importantly) mathematically savvy!
