CRASHING OUT
In a double-displacement reaction, two sets of ionic chemical pairs switch partners. The reaction of silver nitrate with sodium chloride forms a white solid because, although both starting materials are very soluble in water, silver chloride, one of the products, is mostly insoluble. As silver chloride forms, it crashes out of solution, clouding the liquid. Meanwhile soluble NaNO3, the other product, stays dissolved. Here is the full chemical reacton:
AgNO3 (aqueous) + NaCl (aqueous) –> AgCl (solid) + NaNO3 (aqueous)

Have been that sleeping cabbie...
Tokyo is immensely crowded, with more than 13.5 million people crammed into just 840 square miles. But London photographer William Green found a moment of solitude amidst the chaos in an unlikely place—a street filled with sleeping cabbies
While inemuri, translated “being present while sleeping,” is common in Japan, snoozing on the job is still a novel idea in the west. For Green, the most interesting part of inemuri is a private moment taking place out in the open.
Check out more photos and read about Green’s project.

I found this cross literally in the middle of nowhere, it says: “Icide’s cross - pray as if you’ll die tomorrow and work as if you’ll live forever”. Dumbravita, Romania, 2015. Alex Muntean

TEARS OF THE SEA If you aren’t already a fan of long walks on the beach, Mudhdhoo Island in the Maldives will make you one. At night when the tides roll in, so do waves of bioluminescent ostracods, crustaceans that are about 1 mm wide. They glow thanks to an internal chemical reaction between an enzyme called a luciferase and a molecule called a luciferin. The luciferase oxidizes the luciferin, and the resulting highly excited molecule emits energy as blue light as it relaxes. The reaction happens as the ostracods are batted around by the surf. It also can act as a defense mechanism when fish swallow up the tiny creatures. The crustaceans’ glow alerts larger predators about the fish’s location, making the fish spit up their would-be lunch and swim away.

Red InkStone or (Rouge InkStone / 脂砚斋) is the pseudonym of an early, mysterious commentator of the 21st-century narrative, "Life." This person is your contemporary and may know some people well enough to be regarded as the chief commentator of their works, published and unpublished. Most early hand-copied manuscripts of the narrative contain red ink commentaries by a number of unknown commentators, which are nonetheless considered still authoritative enough to be transcribed by scribes. Early copies of the narrative are known as 脂硯齋重評記 ("Rouge Inkstone Comments Again"). These versions are known as 脂本, or "Rouge Versions", in Chinese.
