Quilt complex

The quilt on the left is a Broken Star Variation. As Escher knew so well, there's no such thing as plain geometry. However it's possible to take this too far (ok, I don't really mean that!) Here are some amazing mathematical quilts by Diana Venters and Elaine Ellison, who have written a book, Mathematical Quilts: No Sewing Required.

Well, now it's time for me to quilt while I'm ahead. (I'll let you know how it turns out...)

Hi Nick,

Thanks for this great blog, your posts are fascinating ! It remembers me the very nice experience working a summer at Chalmers research group ;-)

About Mathematical Quilts, it made me think to a man who is also doing art with mathematics : Benoit Mandelbrot.

This man did also a courageous work on market variations, showing how the Black-Scholes model underestimates extremes market variations (assuming errors are distributed like the gaussian curve)...

Thanks again,

about me... I have been doing my Phd in genetic epidemiology on "risk estimation in HNPCC (hereditary non polyposis colorectal cancer) families" for a couple of months now. I find familial data fascinating (at least in a statistical point of view !).

Hi Youenn,

Great to hear from you!

Genetic epidemiology seems to be a very active area of research these days. I wonder if there has been any work on graphical/visualization methods for this ...

One of the most famous paper is probably A haplotype map of the human genome where authors (the list is such huge that some are probably cited twice!) did some amazing graphs to show a new (never plotted!) kind of information. See
Fig. 6
Fig. 8
Fig. 10
Fig. 15.
I have to work my R !

I will let you know if I find some ugly ones ;-)

I already found some ! See the "top ten worst graphs"
A blink of an eye to your blog : the last one (number 10, see the discussion)

Youenn, I especially like Figure 15 from the haplotype map paper. The "top ten worst graphs" were interesting to look at, although I think they are not nearly as bad as some I've produced myself!

I've tried but... no... I can't imagine your "bad graphs"... I guess it may corresponds to one of my bests ? Did you keep one as a relic ? Send me by e-mail if you don't want to publish it ;-) it could become a legend... and I could get a good price !

fascinating stuff, I love math and art and the way they are related. These designs remind of Navajo rugs. Interesting post and great blog. Thanks.
