Needs for Dynamite
During the Transportation Revolution, a big way to build railroads, hollow out mountains for trains, clear out land for ravines, mine for gems and rocks such as gold and granite, was underground. Getting underground was the hard part. Miners longed for an easier way to get to what they needed quicker and faster instead of having to dig and chisel at the rock and ground to get to what they needed. But luckily, in 1867, a Swedish chemist and engineer named Alfred Nobel, came to the rescue.
