New research solves Crystal Palace mystery

New research has solved the mystery of how the Crystal Palace in London, which at the time was the world's largest building, was constructed in only 190 days and completed just in time for the start of the Great Exhibition of 1851. The study has discovered that the Crystal Palace was the first building known to have made use of a standard screw thread -- something that's now taken for granted in modern construction and engineering. Before this, no two nuts and bolts were the same. https://ift.tt/XPrfxT9
