More from Ada Lovelace
"The Analytical Engine has no pretensions whatever to originate anything. It can do whatever we know how to order it to perform."
"I am much annoyed at your having altered my Note. You know I am always willing to make any required alterations myself, but that I cannot endure another person to meddle with my sentences."
"Ada, my dear child, be patient and persevering in your studies."
"The Analytical Engine might act upon other things besides number; were objects found whose mutual fundamental relations could be expressed through abstract operations."
