History of inputs and outputs, the first use of a keyboard to enter commands, the use of punch cards in the 1800s to program looms, and the way in which Aircraft design technology was used to generate the first 3D scan of a human head.
July 4, 1956 – Keyboard and calculator paired for the first time
In 1956, users of the MIT Whirlwind I computer, whose development and construction began in 1948 and ended in 1951, were able to enter commands using a keyboard, first time both devices were used together. (Previously, all computers used punch cards, switches, and numbers for input). Nowadays, touch screens and even voice input are ubiquitous, but keyboards are still essential for our workflows. There is simply no better way to enter text.
July 7, 1752 – Joseph-Marie Jacquard’s date of Birth.
IBM President and Chief Executive Officer Thomas John Watson was way ahead of his time when, in 1949, he predicted that electronics would replace moving parts in a decade. His prediction was wrong, but the future he envisioned was coming true, computers dramatically simplifying machines. Electric vehicles, for example, replace a complex combustion engine with a battery and electronic components, dramatically reducing the number of moving parts in a car.
July 19, 1983 – First 3D CT scan of a human head
On that day, a research team released the first 3D reconstruction of a human head using CT (Computed Tomography). Aircraft design techniques were used to create the images. The authors were Michael W. Vannier (Institute of Radiology Mallinckrodt, St. Louis), J. Marsh (Institute of Cleft Palate and Craniofacial Deformities, St. Louis Children’s Hospital) and J. Warren (McDonnell Aircraft Company). Nowadays, CT scans are commonly used in the diagnosis of concussions and other brain injuries.
July 20, 1976 – Viking I lands on Mars
The Viking I robot was the second soft lander on Mars, after Mars 3 of the Soviet Union, which landed on 2 December 1971, but only backed transmitted data to the Earth for 14.5 seconds. Although the biology experiments of Viking I found no trace of life, it was able to gather information on the composition of the soil on Mars and to capture images of the surface of the planet. its mission lasted more than six years.
July 29, 1914 – First transcontinental phone call
The establishment of a long-distance telephone network in the USA. It began in 1885, but until July 29, 1914, the first phone call was not made in the United States. It was across the continent. However, this was just an internal test. Six months later, Alexander Graham Bell made the long distance public call from New York to his assistant, Mr. Watson in San Francisco, and saying, “Mr. Watson, come here, I want you,” a phrase that he pronounced for the first time when he tested his prototype phone in 1876.
