Modern Marvels: Salt Mines
Overview
It’s the only rock we eat – a priceless commodity essential to our very survival. It has over 14,000 uses – from de-icing our roads to softening our water. We dynamite it from vast caverns deep beneath the earth’s surface, harvest it via solar evaporation from seawater ponds, and mine it with huge hydraulic pipes penetrating to subterranean deposits. The world of salt…something to think about the next time you sprinkle that humble white crystal over your next meal.

The crash test dummy, patron saint of vulnerable motorists, has become a modern icon and is a potent symbol of safety in a risk-obsessed age. But what’s the real story behind this blank-faced semi-human? From a case of mistaken identity in the Roswell UFO incident, to the U.S. military’s top-secret research and development programs of the 1950s, to a series of highly sensitive experiments on humans, animals, and corpses, we chart the bizarre and often gruesome life of this mechanical humanoid.
Episode 49: Great Train Disasters
Throughout railroad history, disasters lay at the heart of progress since expansion and profit proved the main goals of management. In 1875 alone, an average of 22 train accidents happened daily; in 1890, over 6,000 people were killed. We’ll examine how safety, once a secondary consideration, became a primary goal.
