The 19th Century: First Programmable Computing Devices

Until the 19th century "early computers", probably better described as calculating machines, were basically mechanical devices and operated by hand. Early calculators like the abacus worked with a system of sliding beads arranged on a rack and the centerpiece of Leibniz's multiplier was a stepped-drum gear design.

Therefore Charles Babbage's proposal of the Difference Engine (1822), which would have (it was never completed) a stored program and should perform calculations and print the results automatically, was a major breakthrough, as it for the first time suggested the automation of computers. The construction of the Difference Engine, which should perform differential equations, was inspired by Babbage's idea to apply the ability of machines to the needs of mathematics. Machines, he noted, were best at performing tasks repeatedly without mistakes, while mathematics often required the simple repetition of steps.

After working on the Difference Engine for ten years Babbage was inspired to build another machine, which he called Analytical Engine. Its invention was a major step towards the design of modern computers, as it was conceived the first general-purpose computer. Instrumental to the machine's design was his assistant, Augusta Ada King, Countess of Lovelace, the first female computer programmer.

The second major breakthrough in the design of computing machines in the 19th century may be attributed to the American inventor Herman Hollerith. He was concerned with finding a faster way to compute the U.S. census, which in 1880 had taken nearly seven years. Therefore Hollerith invented a method, which used cards to store data information which he fed into a machine that compiled the results automatically. The punch cards not only served as a storage method and helped reduce computational errors, but furthermore significantly increased speed.

Of extraordinary importance for the evolution of digital computers and artificial intelligence have furthermore been the contributions of the English mathematician and logician George Boole. In his postulates concerning the Laws of Thought (1854) he started to theorize about the true/false nature of binary numbers. His principles make up what today is known as Boolean algebra, the collection of logic concerning AND, OR, NOT operands, on which computer switching theory and procedures are grounded. Boole also assumed that the human mind works according to these laws, it performs logical operations that could be reasoned. Ninety years later Boole's principles were applied to circuits, the blueprint for electronic computers, by Claude Shannon.

An Economic and therefore Governmental Issue

While the digital divide might bring up the idea that enterprises will be able to sell more and more computers during the next years another truth looks as if there was no hope for a certain percentage of the population to get out of their marginalization, their position of being "have nots".

Studies show that the issue of different colors of skin play a role in this, but more than "racial" issues it is income, age and education that decides about the have and have nots.

There exist ~ 103 million households in the USA.
~6 million do not even have telephone access. Why should they care about computers?

The digital divide cuts the world into centers and peripheries, not into nations, as it runs through the boarder between the North and the South as well as through nations.

DuPont Company

American corporation engaged primarily in the manufacture of chemicals, plastics, and synthetic fibers. The company was founded by éleuthère Irénée du Pont (1771-1834) in Delaware in 1802 to produce black powder and later other explosives, which remained the company's main products until the 20th century, when it began to make many other chemicals as well. Today DuPont has plants, subsidiaries, and affiliates worldwide. Its headquarters are in Wilmington, Del.

CIA

CIA's mission is to support the President, the National Security Council, and all officials who make and execute U.S. national security policy by: Providing accurate, comprehensive, and timely foreign intelligence on national security topics; Conducting counterintelligence activities, special activities, and other functions related to foreign intelligence and national security, as directed by the President. To accomplish its mission, the CIA engages in research, development, and deployment of high-leverage technology for intelligence purposes. As a separate agency, CIA serves as an independent source of analysis on topics of concern and works closely with the other organizations in the Intelligence Community to ensure that the intelligence consumer--whether Washington policymaker or battlefield commander--receives the adaequate intelligence information.
