Study Notes
Early History of Computing
- Persian astrologer Al-Kashi (1393–1449) built a device to calculate planetary conjunctions, with records surviving and being transported to Europe.
Mechanical Computing Devices
- German mathematician Wilhelm Schickard (1592–1635) developed a simple addition and subtraction device, later destroyed during the Thirty Years’ War.
- French mathematician Blaise Pascal (1612–1662) replicated Schickard's work, building a simplified version of the machine.
Obstacles to Progress
- Wars, famine, and the plague interrupted mechanical computing device development.
- Primitive hardware and limited user interfaces hindered improvement in HCI.
The Need for Navigational Aids
- Agricultural and industrial revolutions in Western Europe increased trade, leading to a need for accurate maps and navigation charts.
- Calculation of precise distances and longitudes fueled the development of computing devices.
Charles Babbage's Contributions
- British mathematician and inventor Charles Babbage (1791–1871) designed the Difference Engine to calculate 6th degree polynomials.
- The Analytical Engine, a general computer, was developed, introducing the problem of programming supply.
- Punched cards were used, solving a user interface problem and dominating computer use for a century.
