Analytical Engine facts
While investigating facts about Analytical Engine Was Invented In and Analytical Engine Images, I found out little known, but curios details like:
Charles Babbage lost 2 games of chess to the Mechanical Turk, an automaton with a chess player hidden inside that fooled people that a machine could play chess. He knew it was a hoax but it inspired his work on the Difference Engine and then the Analytical Engine, the world's first computer.
how analytical engine works?
Ada Lovelace, daughter of poet Lord Byron, is regarded as the first computer programmer. She wrote an algorithm for Charles Babagge's theroetical Analytical Engine in 1842, over 100 years before the development of the first computer.
What was the analytical engine used for?
In my opinion, it is useful to put together a list of the most interesting details from trusted sources that I've come across answering what does the analytical engine do. Here are 14 of the best facts about Analytical Engine Definition and Analytical Engine Meaning I managed to collect.
what did the analytical engine do?

Modern computing can be traced back to fabric making on looms in the early 1800's. Punchcards were used to programmatically weave patterns. Named after their founder, Jacquard Loom cards helped inspire Charles Babbage's Analytical Engine and early IBM computing.

Ada Lovelace, the only legitimate daughter of the famous poet Lord Byron, is widely considered to be the very first "computer programmer" based on her notes for an "Analytical Engine" written more than 150 years ago

One particular area of lifelong interest to Lovelace was music, and she wrote extensively to her mother of the work she was doing in composing music based on numbers, a potential application she envisioned for the Analytic Engine.

She helped write the translation and then wrote the supplemental information to accompany an Italian mathematician's indepth analysis of Babbage's work on his next project, the Analytical Engine.

Ada Lovelace (18151852), an English mathematician and writer, is considered the first computer programmer. Her notes on Charles Babbage's Analytical Engine describes an algorithm for the Analytical Engine to compute Bernoulli numbers.

In 1837 the Analytical Engine, generally considered the first computer, was designed and partly built. If construction had completed it would have predated the first generalpurpose computers by more than a century. The logical structure was essentially the same as modern computers.

Google and the CIA have created a temporal analytics engine to that scours the web and creates curves that predict where events may head.

In her writings on the two machines, Lovelace emphasized the major differences between Babbage's devices, but more importantly, she theorized that there were practical uses and implications for the Analytic Engine that went way past simply doing mathematical computations.

Ada Lovelace, a 19th century mathematician, is often hailed as the first computer programmer. She discovered "conditional branching", wrote about it in her discussion of Charles Babbage's Analytical Engine, and wrote the first algorithm designed to be carried out by the machine.
Why analytical engine is used?
You can easily fact check why was the analytical engine invented by examining the linked wellknown sources.
We could argue that the first computer was the abacus or the slide rule, in 1622. But the first computer resembling computers we know today was the Analytical Engine, a device designed by British mathematician Charles Babbage between 1833 and 1871.
Ada lovelace was english mathematician and writer chiefly known for her work on charles babbage's early mechanical general purpose computer , the analytical engine.  source
