3．Ada Byron was a teenager when she met Cambridge mathematics professor Charles Babbage，who had invented the Difference Engine，a mechanical computer（1）
to produce mathematical tables without mistakes．But he never built the actual machine （2）
financing difficulty．
Babbage was（3）
impressed with the brilliant young woman that they wrote to each other for years，discussing math and computing as he moved on to the（4）
of the Analytical Engine．In 1842，Babbage gave a lecture on the engine at the University of Turin．Ada，now in her late 20s and known as Countess of Lovelace，was （5）
to translate the lecture into English．She （6）
her own notes to it，which was published in 1843．
Lovelace's notes made it clear that she understood the Analytical Engine and Babbage himself（7）
．She suggested the data input that would（8）
the machine to calculate Bernoulli numbers， （9）
is considered the first computer program．Moreover，she understood that numbers could be used to represent （10）
just quantities．It could also be a machine that could（11）
other data like music and science．All that came true - in another 100 years．How did a young woman get the（12）
to show the world her talents in the 19th century？
（13）
，mathematical intelligence was not the only thing Ada Lovelace had going for her．Her（14）
probably came genetically （遺傳），as she was the daughter of the poet Lord Byron and his first wife
Anne Byron．Both were gifted and well （15）
．
Lady Byron，who studied literature，science，philosophy，and，most unusual for a woman，mathematics，was（16）
that Ada should not follow in her father's footsteps．Instead of art and literature，Ada was taught mathematics and science，which she later （17）
herself to．In 1838，she became Countess of Lovelace when her husband was raised to Earl of Lovelace．The noble （高貴的）family background would have landed Lovelace in the history books，but her（18）
in
mathematics made her a pioneer of not only computing，（19）
of women in science．
Lovelace died of cancer at only 36．To remember her contributions to science and engineering，October 13，Ada Lovelace Day is （20）
to learn about women in science，technology，engineering，and mathematics．
