It is becoming increasingly clear, in my opinion, that we need to further shift from an overall economic system based on a linear model of extraction-manufacture-use-waste to a more circular model where as much waste as possible becomes feedstock for another manufacturing process. It also seems clear, after reading about such things for a long […] The post Upcycling Plastic and Reducing Mineral Waste first appeared on NeuroLogica Blog.

In the village of Bellewstown, about 15 miles north of Dublin, Ireland, they still talk about what Barney Curley did back in 1975. It all happened during a horse race on the Hill of Crockafotha. It was just an amateur jockey race on a lazy summer day in a sleepy, remote town; it wasn’t meant to be anything special. The last thing anyone expected was to witness the making of history. The race in question occurred on 26 June 1975. Barney Curley–our protagonist, if you could call him that–owned one of the horses running later that day. But at the racecourse, as preparations were being made, Curley was nowhere to be seen. And not because he wasn’t in attendance–it was because he was taking great pains to stay out of sight. If the trackside bookmakers caught wind that he was at Bellewstown that day, or if they discovered that he was the owner of one of the horses, they would be on full alert, and take precautions with the wagers and odds. Curley had earned a reputation in horse racing circles–he was known to engage in some gambling shenanigans from time to time. But the shenanigan he was planning that day was his most ambitious to date, hands-down. As the spectators placed their wagers and settled in around the edge of the track for a pleasant afternoon of laid back horse racing, Curley was concealed in the thicket of gorse shrubs in the center section of the oval-shaped track. This particular infield wasn’t ideal for human occupation, it was all dust and thorns. Nevertheless he stood in his trademark felt fedora, shrouded by tall shrubbery, far from the other spectators, a pair of binoculars pressed to his eyes. In the distance the loudspeaker announced, “They’re off!” Curley tugged his hat down tight over his bald head as if he could hide inside of it, and peered through his field glasses toward the rumble of horse hooves. In the next five minutes, if everything went according to plan, all of Barney Curley’s considerable money troubles would be over. If the plan went sideways–if his animal was not up to the task, or there was one inopportune stumble–he would be utterly ruined. Continue reading ▶

Recent progress on both analog and digital simulations of quantum fields foreshadows a future in which quantum computers could illuminate phenomena that are far too complex for even the most powerful supercomputers.
