Reduced from a roar to a trickle.
Autumn 1969, the Niagara Falls verged on collapse.
So was the prediction made by the United States Engineering Corps. They believed that the constant rushing of the water was causing damage at the base of the cliff, destabilising the rock. Year on year retreat due to erosion was fine, but any major rock collapse could cause damage to anywhere downstream. They needed to perform a geological survey of the cliff and perform what work was necessary. The Niagara Falls push 2800 metric tons of water over the edge every single second, somewhat of a problem.
They needed to get rid of the water, and the Army Corps of Engineering did exactly that. An operation of great scale and precision, they removed the water from the waterfall. It was rerouted through a newly cut riverbed which allowed the water to rejoin the river further down. For the first time in the history of the United States, they could see the dry cliffs, and the desiccated riverbed. Read more



You may have heard that, “more Monopoly Money is printed each year than is printed by the United States.” This is utterly false, which is a shame, but at least you know now.
When Sony was busy creating the Compact Disc or CD, they had a problem to contend with: how much data should it store? The more data they could store, the more expensive it would be and so on. In the end they chose a limit; the average CD today can hold 74 minutes worth of music.
Light travels very quickly, about 30 million metres per second, but that is only when traveling through a vacuum. Now we know how fast light is let us get some figures of relative relevance. If you were to perform the calculations you would find that light takes all of eight minutes to get from the sun to the earth.
In 1971 a small group of Soviet Scientists were rooting around the small village of Dervaza. The village crucially lies in the Ahal Province of Turkmenistan, an area known for its abundance in one useful resource… Natural Gas. They found it. A site was identified next to the village and preparations were made for the drilling rig and camp to be set up on site, so as to facilitate the gathering of the sweet combustible resource.
Antarctica is the only continent on earth that does not have an indigenous species of ant.
