- The Eiffel Tower was built in 1889 for the Paris Centennial Exhibition and was planed to be taken down after twenty years despite numerous critics clamoring for immediate removal. In 1907, the French government decided the tower would be permanent, it was too good of a radio antenna to destroy.
- In 1822, Charles Babbage invented a steam-powered mechanical calculator called a difference engine. It was never built, however. Each time he started building his machine, he discovered an upgrade and stopped. He then made hundreds of drawings for a punch-card computer the size of a small train which could add and subtract forty digit numbers in a few seconds. His plans were too advanced, however, and his computer was never made. In 1991, a fully functional difference engine was built from his original plans. The first modern computer was built in 1946.
I appreciate your patience with my lack of posts as I wind up my school year. I'm very busy at the moment. Thanks for understanding.
