Stitch Markers
Custom-made by my friend Jennie:
Remember Jennie, the non-knitter?
Aren't they exquisite?
But what's that underneath the beautiful stitch markers, you ask? Why it's everything you never always wanted to know about calculating light echoes around variable stars and cataclysmic events! And on that note, I should get back to those calculations...
PS - The markers aren't as big as they look in the photos - the type on the page is just really small! =)

Aw, yay! I'm so glad you like them! (And I'm so glad I found them.)
Very pretty!
I've never heard of light echos... though really, you don't learn much about astrophysics when you major in chemistry. Sounds interesting to me

Hehe, yeah they probably don't teach you much astro...although we do learn a decent bit of chemistry in relation to properties of the gases in stars. The Cliff's Notes version of the paper is that if you have a star that has an outburst (like a mini-explosion) where the top layers of the star are blown away in a shell, then that star brightens later on, the light will echo off the shell of ejected material from the previous outburst. Does that make sense?
Yeah, that does make sense, thanks
It might be a little mean, but I'm kinda glad people have to learn chemistry, it sort of makes up for making me study biochemistry lol :)

Ick, I'm so glad I never have to study bio! Interestingly enough, today's APOD (Astronomy Picture of the Day) features a light echo: http://antwrp.gsfc.nasa.gov/apod/ap080203.html That one is way cooler than what I'm looking at, but the same general idea. =)
Cool, thanks for the link. I go there when I remember, but that isn't daily
They are fantastic! The owner of the LYS in my new town wants me to teach a fair isle knitting class! I just did my first fair isle project, and she thought I was good enough to teach it! How awesome is that? Don't let all the reading get ya down! Any new projects???
