Real excited photons!
Now this particular breakthrough in light infotainment has to be useful ...University of Pittsburgh researchers have become the first to detect a fundamental particle of light-matter interaction in metals, the exciton. The team will publish its work online June 1 in Nature Physics
Mankind has used reflection of light from a metal mirror on a daily basis for millennia, but the quantum mechanical magic behind this familiar phenomenon is only now being uncovered.
...
Excitons, particles of light-matter interaction where light photons become transiently entangled with electrons in molecules and semiconductors, are known to be fundamentally important in processes such as plant photosynthesis and optical communications that are the basis for the Internet and cable TV. The optical and electronic properties of metals cause excitons to last no longer than approximately 100 attoseconds* (0.1 quadrillionth of a second). Such short lifetimes make it difficult for scientists to study excitons in metals, but it also enables reflected light to be a nearly perfect replica of the incoming light.*For context, an attosecond is to a second what a second is to about 31.71 billion years, or more than twice the age of the universe. - that's a hell of a refresh rate!

It's always a source of wonder to me, the way rainbows and reflections are individualised communions, and communicatications - optic nerve-centric photonic barrages - yet coherent signals.
They move with you, everything is relative!we walk in light...

Looks like the letterbox predictor got it right then....

Jos,
Wow I would love a future indicator like that, though I'd make every choice nice and happy to start the day on a good note. No Dice Man choices for me..

Beautiful.

still life at Heads much more picturesque than this still life at Northern Club

Jos,
That's probably a bag of anonymous party donation money...

Jos,
Where borer have been eating the glue between a photo and the cardboard it had been applied to, they used to use horses' hooves to melt down into adhesive, yum say the insects. There were few holes through the photo thank goodness, easy to fix.

:) perfect!

There is …
Still life in the backyard
Still life in the frontyard
And...
still life at Taipa Beach -

Keep your photos away from flying hoofs!

Saw these flowers at the dairy, and thought they needed to be captured for posterity.
