Tomorrow ere fresh morning streak the east With first approach of light, we must be risen, And at our pleasant labour, to reform Yon flowery arbours, yonder alleys green

Atlas V is an incredible rocket, and one I will miss dearly. Last night the final Atlas V 551 put on a show that can only be described as breathtaking. I have had one shot in mind for this variant for years, and not only did I finally get it on my last chance, it might be my best work yet.

I sometimes enjoy reading ancient history as it was known to later ancients. Plato had an understanding of environmental history which I find interesting both for what he knew and for what he didn't know.

My personal bugbear is the "wildlife numbers have declined by 73% in 50 years" line people get from WWF. That is a fact about a set of populations but not a fact about their sum! Its relationship to what you're thinking of is highly sensitive to the relative sizes of the populations involved!

Most alfalfa grown in the US stays in the US and most alfalfa grown in Arizona stays in Arizona. The problems with irrigating alfalfa fields in the Southwest are mostly not about the export market.
