This came across my Facebook this evening from a photomicrography group I belong to. Mixed diatoms from the Gulf of Thailand at 20x magnification.

Diatoms, if high school biology seems a long, long time ago, are microalgae that live mostly in water. Actually, these are dead diatom skeletons, which are made of silicon. Diatoms make 20% of the world’s oxygen and comprise almost half the organic stuff in the ocean. Also, they’re purty.

I have now done everything I intend to do in aid of that Christmas thing — which mostly involved tidying the kitchen this evening. Tomorrow, I have an hour’s work, an hour’s coffee with my colleagues and then I’m off until January 3.

But I’ll be here if you’re looking for me.
