He is famous for his mechanical machines he designed, the Difference Engine and the Analytical Engine, though he did not actually fully build them. They were completed by others after he died. He is also credited with inventing other things. He invented the frame at the front of locomotives that help clear items from a rail line, which is called a pilot or a cow catcher. He also invented an ophthalmoscope, a device for examining the eye.
The Analytical Engine and The Difference Engine
Babbage is most often credited with inventing the first digital computer and first automatic computer. Lily-chan :]
The name is not BABBLE but BABBAGE. For a full history of Babbage, including the two Difference Engines and the Analytical Engine, please see the link.
In 1834 Charles Babbage (1791-1871) designed the forerunner of the computer, the mechanical Analytical Engine. It was designed to perform complicated calculations such as multiplication, division, addition, and subtraction.
Charles Babbage was the eldest of four children born to Benjamin and Betty Plumleigh Babbage. His mother gave birth to a son, Henry, in October 1874, but the child died in infancy. In May 1876, she gave birth to another son, whom they also named Henry, who died as a small child. Finally, in March 1878, Betty bore a fourth child, a girl, named Mary Anne. Charles and Mary Anne had a warm, lifelong relationship. He preceded her in death.
Charles Babbage (1791-1871) and Augusta Ada King, nee Byron, Countess of Lovelace (1815-1852) were both dead long before 1883 so they didn't invent any machine in that year. Babbage did design an Analytical Engine and Ada Lovelace (as she is better known) wrote an 1843 note on the engine which included what is now recognised as being the first algorithm intended for processing by machine. She is therefore regarded as being the world's first programmer. The algorithm itself was intended to calculate Bernoulli numbers. Babbage is also credited as being the father of the computer for his earlier work designing a Difference Engine and later work on Difference Engine No. 2. However, his designs were never built during his lifetime. Two working models of his designs for Difference Engine No. 2 were built from 1989 to 1991. The earlier design is privately owned by Nathan Myhrvold while the later design resides at the London Science Museum.
Charles Babbage invented the concept of the computer as we know it today. His mechanical "Difference Engine" incorporated the ideas of stored programs, centralized processing, and input/output stages. Unfortunately his design required more-precise metalworking techniques than were available in the mid-19th century, so he was unsuccessful at building a working Difference Engine. It remained until the 20th century for his ideas to be incorporated into electromechanical, and later electronic, computers. In the 1980s the British Museum built a replica of part of the Difference Engine using modern metals an machining methods. It worked exactly as Babbage had proposed.
The main differences between Elna and Janome sewing machines lie in their design, features, and pricing. Elna machines are known for their sleek and modern design, while Janome machines are often praised for their durability and ease of use. Elna machines may have more advanced features and higher price points, while Janome machines are generally more affordable and user-friendly. Ultimately, the choice between the two brands depends on individual preferences and sewing needs.
