An eyeglass manufacturer has decided to get into the subvert-the-surveillance-state business. You need the IR-opaque lenses to be pretty big. They have to obscure your cheekbones to rob the algorithm of enough data to matter, I bet.

I love the look of anticipation and optimism in the face of this wire, gazing at electrons across the mysterious barrier (swiped the pic from the Nobel web site's announcement of this prize):

Last night's full moonrise from the back deck with my iPhone and with my Seestar telescope. Taken low in the sky, a bit after 9:30, so the Seestar image is sill a bit red-shifted because the moonlight is filtered by so much atmosphere.
