Douglas Carl Engelbart (January 30, 1925 – July 2, 2013) was an American engineer, inventor, and a pioneer in many aspects of computer science.He is best known for his work on founding the field of human–computer interaction, particularly while at his Augmentation Research Center Lab in SRI International, which resulted in creation of the computer mouse, [a] and the development of ...
Jean-Daniel Nicoud (born 31 August 1938), is a Swiss computer scientist, noted for inventing of a computer mouse with an optical encoder and the CALM (Common Assembly Language for microprocessors). [1] He obtained a degree in physics at the École Polytechnique Fédérale de Lausanne (EPFL) in 1963. Around 1965, he became interested in logical ...
The plural for a computer mouse is either "mice" or "mouses" according to most dictionaries, with "mice" being more common. [7] The first recorded plural usage is "mice"; the online Oxford Dictionaries cites a 1984 use, and earlier uses include J. C. R. Licklider's "The Computer as a Communication Device" of 1968. [8]
Since its inception in the mid-'60s, the "mouse," as it came to be known, has morphed and mutated into a diverse assortment of styles to accommodate efficiency, ergonomics and portability.
The first prototype of a computer mouse, as designed by Bill English from Engelbart's sketches [1]. Early dynamic information devices such as radar displays, where input devices were used for direct control of computer-created data, set the basis for later improvements of graphical interfaces. [2]
The history of the use of cadavers is filled with controversy, scientific advancements, and new discoveries. Beginning in the 3rd century ancient Greece two physicians by the name of Herophilus of Chalcedon and Erasistratus of Ceos [ 6 ] practiced the dissection of cadavers in Alexandria, and it was the dominant means of learning anatomy. [ 7 ]
A key principle in the dissection of human cadavers (sometimes called androtomy) is the prevention of human disease to the dissector.Prevention of transmission includes the wearing of protective gear, ensuring the environment is clean, dissection technique [2] and pre-dissection tests to specimens for the presence of HIV and hepatitis viruses.

The first recorded idea of using digital electronics for computing was the 1931 paper "The Use of Thyratrons for High Speed Automatic Counting of Physical Phenomena" by C. E. Wynn-Williams. [29] From 1934 to 1936, NEC engineer Akira Nakashima , Claude Shannon , and Victor Shestakov published papers introducing switching circuit theory , using ...
