Computing at Columbia Timeline
Computing at Columbia Timeline
At the dawn of the new Millenium, computers and the network are ubiquitous; we can't live without them. It wasn't always so. How did we get here? A series of technological innovations including Pascal's adder (the Pascaline, 1600s), Leibnitz's multiplier (the Stepped Reckoner, about 1700), the Jacquard loom (1804), the Babbage Analytical and Difference Engines (1820s-30s), electricity and electromagnetism, the telegraph, the Hollerith tabulating machine (1890), the relay, the vacuum tube, core memory, the transistor, the laser, the integrated circuit, and on and on, each resulted in products that stimulated applications, which in turn stimulated the demand for more and better products, and before long computers entered the economy and the popular culture.
