An Injection of Chaos Solves Decades-Old Fluid Mystery

In the 1960s, drillers noticed that certain fluids would firm up if they flowed too fast. Researchers have finally explained why. The post An Injection of Chaos Solves Decades-Old Fluid Mystery first appeared on Quanta Magazine

Fluids can be roughly divided into two categories: regular ones and weird ones. Regular ones, like water and alcohol, act more or less as expected when pumped through pipes or stirred with a spoon. Lurking among the weird ones — which include substances such as paint, honey, mucus, blood, ketchup and oobleck — are a vast variety of behavioral enigmas that have stumped researchers over the...
