Merchants, traders and clerks in some parts
of Eastern
Europe, Russia, China and Africa use
abacuses, and they are still used to teach
arithmetic to children.[1] Some people who
are unable to use a calculator because of
visual impairment may use an abacus.

21. Alan Turing's work could be said to have begun the digital
revolution. Although others around the world, such as the
American, Alonzo Church, had done some work, it was Alan
Turing who envisaged and designed a machine that could be
given a rule set, upon which it would base its actions and could
therefore be programmed to solve an infinite number of
problems: in fact, any problem for which there was a
solution(basically a modern computer). It was Alan Turing who
was instrumental in the development of the Bombe at Bletchley
Park and it was Alan Turing whose ground-breaking ideas about
Artificial Intelligence (AI) really pushed the boundaries of
mathematical thinking at that time.

23. He quickly became one of the government's greatest assets,
with the cracking of Germany's Enigma code shortening the
war by two to four years and saving an estimated 14 million
to 21 million lives, historians claim.

navigation, street view, and
public transit information.

36. The Imitation Game is a
2014 American historical
drama film directed by
Morten Tyldum and written by
Graham Moore, based on the
biography Alan Turing: The
Enigma by Andrew Hodges.

37. Three brilliant African-American
women at NASA -- Katherine
Johnson (Taraji P. Henson), Dorothy
Vaughan (Octavia Spencer) and Mary
Jackson (Janelle Monáe) -- serve as the
brains behind one of the greatest
operations in history: the launch of
astronaut John Glenn (Glen Powell)
into orbit, a stunning achievement
that restored the nation's
confidence, turned around the
Space Race and galvanized the
world.
