When was the last time the lunar eclipse and winter solstice coincided?

• The U.S. Naval Observatory says 1638;
  

• Starhawk, a prominent Wiccan, puts it at 1544.
  

Whatever the answer, it is a rarity! My daughter saw it go "copper coloured" when she was in work (Much to the annoyance of her mum); in case you missed it, here is a time lapse video shot by William Castleman in Gainesville, Florida.

Magnetic Resonance Imaging of Foods (MRI Scans of Food)

The Inside Insides blog features animated MRI scans of food which I'm sure has a number of uses in teaching & learning.

I think I must be getting behind the times because I'd not heard of John Conway's Game of Life!

However I came across sixfoottallrabbit's implementation of John Conway's Game of Life using the HTML 5 canvas element.

"What does that mean?"

It means that it consists of a grid of cells which can be in one of a finite number of states. Given any state, there are rules that govern what the next state of the grid will be.

We are looking at l...
