Babbage's Analytical Engine

World War 2 (1939-1945)

A global war that lasted from 1939 to 1945, although related conflicts began earlier. The vast majority of the world's countries—including all of the great powers—eventually formed two opposing military alliances: the Allies and the Axis. The Empire of Japan aimed to dominate Asia and the Pacific and was already at war with the Republic of China in 1937, but the world war is generally said to have begun on 1 September 1939, the day of the invasion of Poland by Nazi Germany and the subsequent declarations of war on Germany by France and the United Kingdom.

Analytical Engine

1st mechanical computer. Ran off of punched cards. Created by Charles Babbage, but never completed by him.

Universal Turing Machine (UTM)

A UTM, U, is an interpreter that reads the description <M> of any arbitrary Turing machine M and faithfully executes operations on data D precisely as M does. For single-tape Turing Machines, imagine that <M> is written at the beginning of the tape, followed by a D.

Charles Babbage

He is known as the "Father of Computers." He developed the Difference Engine and the Analytical Engine. These two machines were powered by steam to move the punch cards and operate the gears. His ideas were later used to design calculators and computers.

Konrad Zuse

Invented the first functional program controlled computer

Alan Turning is known for developing

a test that tests a machine's ability to display intelligent behavior
