In 1884, Charles Babbage, an English mathematician, tried to build a complicated machine called the “analytical engine.” It was mechanical, rather than electronic, and Babbage never completed it, but computers today are based on many of the principles he used in his design. In our discussion this week, discuss other inventions that changed the way we work and live. Try to trace changes and refinements in those inventions within your initial post.
An example might be the sewing machine, which originally, was mechanical, rather than electric, and had to be operated by a foot pedal. Another might be the phonograph, which evolved into the CD player.
