“Our oceans have been the victims of a giant Ponzi scheme, waged with Bernie Madoff–like callousness by the world’s fisheries. Beginning in the 1950s, as their operations became increasingly industrialized–with onboard refrigeration, acoustic fish-finders, and, later, GPS–they first depleted stocks of cod, hake, flounder, sole, and halibut in the Northern Hemisphere. As those stocks disappeared, the fleets moved southward, to the coasts of developing nations and, ultimately, all the way to the shores of Antarctica, searching for icefishes and rockcods, and, more recently, for small, shrimplike krill. As the bounty of coastal waters dropped, fisheries moved further offshore, to deeper waters. And, finally, as the larger fish began to disappear, boats began to catch fish that were smaller and uglier–fish never before considered fit for human consumption.” Link@tnr.com

“One of the most famous unperformed experiments in science is Schrödinger’s cat. In 1935 Erwin Schrödinger, who was one of the pioneers of quantum mechanics, imagined putting a cat, a flask of Prussic acid, a radioactive atom, a Geiger counter, an electric relay and a hammer in a sealed box. If the atom decays, the Geiger counter detects the radiation and sends a signal that trips the relay, which releases the hammer, which smashes the flask and poisons the cat. The point of the experiment is that radioactive decay is a quantum process. The chance of the atom decaying in any given period is known. Whether it has actually decayed (and thus whether the cat is alive or dead) is not—at least until the box is opened. The animal exists, in the argot of the subject, in a “superposition” in which it is both alive and dead at the same time.” article@economist.com
