The Atlantic: What I Saw Treating the Victims From Parkland Should Change the Debate on Guns. “They weren’t the first victims of a mass shooting the Florida radiologist had seen—but their wounds were radically different.” By Heather Sher, radiologist.
“In a typical handgun injury that I diagnose almost daily, a bullet leaves a laceration through an organ like the liver. To a radiologist, it appears as a linear, thin, grey bullet track through the organ. There may be bleeding and some bullet fragments.
I was looking at a CT scan of one of the victims of the shooting at Marjory Stoneman Douglas High School, who had been brought to the trauma center during my call shift. The organ looked like an overripe melon smashed by a sledgehammer, with extensive bleeding. How could a gunshot wound have caused this much damage?”

“An important detail is that the switching over of detecting apparatus must be faster than the time the photon has to travel to the detectors. This way, there is no way the photon could “know” what to do. (If a photon knows anything, anyway.) Experiments presented in October extended the range of the photon’s trip to about 2,200 miles, and still the photon seems to always choose the path consistent with the delayed choice. It is as if — Mike McRae wrote in this Science Alert piece — “that even after the horse has bolted 2,200 miles out of the gate, it can still wait until the finish line to decide which race it ran.” That is, which path to the finish line it took.”
