Supernumerary Rainbows over New Jersey
Credit & Copyright: John Entwistle

Yes, but can your rainbow do this? After the remnants of Hurricane Florence passed over Jersey Shore, New Jersey, USA last month, the Sun came out in one direction but something quite unusual appeared in the opposite direction: a hall of rainbows. Over the course of a next half hour, to the delight of the photographer and his daughter, vibrant supernumerary rainbows faded in and out, with at least five captured in this featured single shot. Supernumerary rainbows only form when falling water droplets are all nearly the same size and typically less than a millimeter across. Then, sunlight will not only reflect from inside the raindrops, but interfere, a wave phenomenon similar to ripples on a pond when a stone is thrown in. In fact, supernumerary rainbows can only be explained with waves, and their noted existence in the early 1800s was considered early evidence of light's wave nature.

Well-done profile of the outstanding +Lea Kissner, who was once a colleague of mine at BBN Technologies before being a colleague of mine at Google.

Bravo to Luis M. Milán Leal for his entry in David Brin's thread of quick-short-stories on what happens to Elon Musk's red roadster.

Amontillado.

David woke up, with a headache.

"Very funny, Elon". He tried to move, but found his body completely unresponsive. A closed faceplate prevented him from seeing where he was. His stomach felt odd, and he felt weightless. Must be the drugs.

"Spiking the amontillado? That's low even for you, Elon." He struggled again. "She said she loved me, but that's no reason to get vindictive, you jealous bastard. Now let me out of here!"

The faceplate lifted. He stared at the stars.

A small, tinny voice echoed inside his helmet. "Enjoy your trip, David."

He started laughing, in despair.

Woo hoo! Web page speed will, at last, contribute to Google search results ranking on mobile devices. A huge amount of work, on both the Google Search and the Chrome metrics sides, went into this launch.
