The moon

I wanted to do something to celebrate the announcement that gravitational waves - predicted by Einstein in 1916 - have finally been observed.  My physicist friend says "Simply amazing. What a time to be alive. Higgs now this."  She gave me a couple of links - A beginner's guide .. and a video from people involved at Glasgow University .


I cut out the moon from a photo taken tonight, and pasted it onto a  background image.
