no, how could he, he never built any.
Never, the Abacus existed more than 5000 years before Babbage was born and Babbage never had any need for one.
No, Leonardo didn't ever sell any of his pieces according to everything I've ever heard (and I've heard a lot because I'm doing a project on him)
For the same reason as any other global company, profit.
No, video did not exist in the 1800s.
Ada Augusta Countess of Lovelace is credited as being the first computer programmer as she wrote programs for Babbage's Analytical Engine. However she never was able to run any of them as the machine was never built.
Charles Babbage's inspiration came from a desire to find a way to do mathmetical equations faster, easier and without any errors.
did verizon sell i phone 4g at any time in recent past months?
No, the ancient Egyptians did not invent the way computers do math. The invention of modern computers and their mathematical operations is credited to many scientists and mathematicians, including Charles Babbage, Ada Lovelace, and Alan Turing. The Egyptians did, however, make significant contributions to mathematics, including advancements in geometry and numerical systems.
In 1822, Charles Babbage develops a working model of a mechanical computer called Difference Engine powered by steam. It can store the programs to perform calculations and print the result automatically. Later in the year 1837, he designs the first mechanical computer knows as Analytical Engine which could do the complicated calculation and store the result at each stage. This Analytical Engine laid the basis for the modern computer due to which Charles Babbage is also known as the Father of Computers.
That was his REAL name - he was never known by any other.
five? he only designed three and never built any.
The history of computers goes way back to a history that is unknown. There is one man who started a significant project to build something people consider to be the first computer. This man was Charles Babbage. Pre-1822 tables for just about everything mathematical (multiplication, climate, stocks) and had to be made by human mathematicians nicknamed "computers". Being human, these "computers" made many errors. Charles Babbage convinced the British government that he could make a machine that could make accurate tables. Granted a sum of money, Babbage started working on his machine, the "difference engine". Ten years later, Babbage made a working part of the difference engine. It could accurately compute 5 digit numbers for tables. However, this was only a small part of the proposed machine. Due to the lack of results and the skyrocketing prices, the government had to withdraw from the funding. Without the support from the government, Babbage started to build a new machine that was superior to the difference engine and could solve any mathematical question. Enter, The Analytical Engine. Although Babbage did not finish the Difference Engine nor the Analytical Engine due to death, these to machines were considered the first to legitimate computers even though they used mechanical parts such as gears and shafts. I hope this was helpful.
