Black Marble: The Earth at Night

Screen Shot 2018-01-29 at 12.03.31 PM

From The Atlantic: "For three weeks spread out over April and October of 2012, the Suomi NPP satellite (jointly of NASA and NOAA) scanned all the Earth's land as it appeared at night. Scientists then mapped the satellite's data — 2.5 terabytes — over an earlier Blue Marble image, transforming that picture's daytime blues, browns, and greens into a night time palette of blues, blacks, and gold."

"The Suomi NPP's Visible Infrared Imaging Radiometer Suite can detect lights as faint as a lone highway lamp — meaning pretty much any human outcropping where electricity runs. 'Nothing tells us more about the spread of humans across the Earth than city lights,' says NOAA scientist Chris Elvidge. When you watch the video above (best in full screen), you can see at the horizon how daylight masks human development but, as the land falls dark, the signals of our settlements glow bright, giving us 'a global view of the human footprint on the Earth.'"

Experts' Experts — Do different ways of using citrus peel to garnish cocktails produce different tastes?


Above, the lead question in the January & February 2013 issue of Cook's Illustrated's Notes From Readers section.

The good people at that magazine — as obsessive a group as ever existed outside Jony Ive's secret studio in Cupertino — drilled down deep as only they do to bring us all back enlightenment, in the form of the following reply.

There are three common citrus garnishes for cocktails: The first is a "twist, " a simple disk of citrus peel that is squeezed into the drink to release essential oils and then rubbed around the rim of the glass and discarded. The second is a "flamed twist," in which a flame is held between the drink and the peel so that when the peel is squeezed, its oils ignite briefly. The third type is a "swatch," a band of zest with a little pith attached that is twirled and placed in the drink. We made all three types of garnishes with orange peel and tasted each in a simple Negroni cocktail. We found that the twist contributed bright orange notes that enlivened the drink. The flamed twist offered sulfurous undertones and had a somewhat subdued orange fragrance. The swath added citrus notes along with mild bitterness from the pith. In sum, fancy citrus garnishes are more than just ornamental: Your choice should hinge on the flavor profile you're trying to create.

What are they?


Answer here this time tomorrow.

Hint: smaller than a bread box.

Another: made in Watsonville, California.

A third: edible — yet not made out of some kind of fungus or rotting fish product, nor are they blown-up from microscopic scale.
