The Gemini AO laser as seen from Cerro Tololo


The Gemini telescope uses a powerful laser as part of its adaptive optics system.  This 253s image was taken from Cerro Tololo and clearly shows the laser pointing straight up against a background of stars rotating overhead. (Click for larger)

Excited Dog

I went for a walk on the beach beside the construction site of a new condo.  They were pumping out the marsh (on which they’re building an enormous complex, on sand, in an earthquake zone, next to a beach known for its tsunamis) and the water was this evil orange color.  A stray dog thought I was the best thing ever and played around me.

Self Help Books

Most self help books are written in two halves.  In the first half, the author tries to convince you that there is a problem.  Most of the time, this is a problem you may suppose that you have and so are predisposed to believe what the author says.  In the second half, the author tries to convince you he or she has the solution to your problem.

Now imagine such a book written by someone who doesn’t like you.

(With a bit of luck, you’ll never pick one up again.)
