Roger Gregory (programmer)
Roger Everett Gregory is a US computer programmer, technologist, and scientist. Gregory's work in project Xanadu made him one of the earliest pioneers of hypertext technology, which helped lay the foundations for the hyperlink technology that underlies the World Wide Web. Gregory attended the University of Michigan as a mathematics major. In the 1970s, he founded the Ann Arbor Computer Club, similar to the West Coast's Home Brew Computer Club. In 1974 Gregory met Theodore Holm (Ted) Nelson, the author of Computer Lib/Dream Machines, and the thinker who coined the term "hypertext". The pair became friends. In 1979 Nelson convinced Gregory to move from Michigan and join him in Swarthmore, Pennsylvania, the small, sleepy college town outside of Philadelphia where Nelson earned his undergraduate degree, and first conceived the concept of a hypertext. Gregory's first summer in Swarthmore, characterized by Xanadu insiders as the ''"Swarthmore Summer"'', was a productive time, wh ...

Project Xanadu
Project Xanadu ( ) was the first hypertext project, founded in 1960 by Ted Nelson. Administrators of Project Xanadu have declared it superior to the World Wide Web, with the mission statement: "Today's popular software simulates paper. The World Wide Web (another imitation of paper) trivialises our original hypertext model with one-way ever-breaking links and no management of version or contents." ''Wired'' magazine published an article called "The Curse of Xanadu", calling Project Xanadu "the longest-running vaporware story in the history of the computer industry". The first attempt at implementation began in 1960, but it was not until 1998 that an incomplete implementation was released. A version described as "a working deliverable", OpenXanadu, was made available in 2014. History Nelson's vision was for a "digital repository scheme for world-wide electronic publishing". Nelson states that the idea began in 1960, when he was a student at Harvard University. He proposed a mach ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robert Goddard
Robert Hutchings Goddard (October 5, 1882 – August 10, 1945) was an American engineer, professor, physicist, and inventor who is credited with creating and building the world's first Liquid-propellant rocket, liquid-fueled rocket. Goddard successfully launched his rocket on March 16, 1926, which ushered in an era of space flight and innovation. He and his team launched 34 rockets between 1926 and 1941, achieving altitudes as high as and speeds as fast as 885 km/h (550 mph). Goddard's work as both theorist and engineer anticipated many of the developments that would make spaceflight possible. He has been called the man who ushered in the Space Age. Two of Goddard's 214 patented inventions, a multi-stage rocket (1914), and a liquid-fuel rocket (1914), were important milestones toward spaceflight. His 1919 monograph ''#A Method of Reaching Extreme Altitudes, A Method of Reaching Extreme Altitudes'' is considered one of the classic texts of 20th-century rocke ...

Year Of Birth Missing (living People)
A year or annus is the orbital period of a planetary body, for example, the Earth, moving in its orbit around the Sun. Due to the Earth's axial tilt, the course of a year sees the passing of the seasons, marked by change in weather, the hours of daylight, and, consequently, vegetation and soil fertility. In temperate and subpolar regions around the planet, four seasons are generally recognized: spring, summer, autumn and winter. In tropical and subtropical regions, several geographical sectors do not present defined seasons; but in the seasonal tropics, the annual wet and dry seasons are recognized and tracked. A calendar year is an approximation of the number of days of the Earth's orbital period, as counted in a given calendar. The Gregorian calendar, or modern calendar, presents its calendar year to be either a common year of 365 days or a leap year of 366 days, as do the Julian calendars. For the Gregorian calendar, the average length of the calendar year (the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Squeak
Squeak is an object-oriented, class-based, and reflective programming language. It was derived from Smalltalk-80 by a group that included some of Smalltalk-80's original developers, initially at Apple Computer, then at Walt Disney Imagineering, where it was intended for use in internal Disney projects. The group would later go on to be supported by HP labs, SAP, and most recently, Y Combinator. Squeak runs on a virtual machine (VM), allowing for a high degree of portability. The Squeak system includes code for generating a new version of the VM on which it runs, along with a VM simulator written in Squeak. Developers Dan Ingalls, an important contributor to the Squeak project, wrote the paper upon which Squeak is built, and constructed the architecture for five generations of the Smalltalk language. Alan Kay is an important contributor to the Squeak project, and Squeak incorporates many elements of his proposed Dynabook concept. User interface frameworks Squeak includes four ...

Routledge
Routledge () is a British multinational publisher. It was founded in 1836 by George Routledge, and specialises in providing academic books, journals and online resources in the fields of the humanities, behavioural science, education, law, and social science. The company publishes approximately 1,800 journals and 5,000 new books each year and their backlist encompasses over 70,000 titles. Routledge is claimed to be the largest global academic publisher within humanities and social sciences. In 1998, Routledge became a subdivision and imprint of its former rival, Taylor & Francis Group (T&F), as a result of a £90-million acquisition deal from Cinven, a venture capital group which had purchased it two years previously for £25 million. Following the merger of Informa and T&F in 2004, Routledge became a publishing unit and major imprint within the Informa "academic publishing" division. Routledge is headquartered in the main T&F office in Milton Park, Abingdon, Oxfordshire and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wired Magazine
''Wired'' (stylized as ''WIRED'') is a monthly American magazine, published in print and online magazine, online editions, that focuses on how emerging technologies affect culture, the economy, and politics. Owned by Condé Nast, it is headquartered in San Francisco, California, and has been in publication since March/April 1993. Several spin-offs have been launched, including ''Wired UK'', ''Wired Italia'', ''Wired Japan'', and ''Wired Germany''. From its beginning, the strongest influence on the magazine's editorial outlook came from founding editor and publisher Louis Rossetto. With founding creative director John Plunkett, Rossetto in 1991 assembled a 12-page prototype, nearly all of whose ideas were realized in the magazine's first several issues. In its earliest colophon (publishing), colophons, ''Wired'' credited Canadian media theorist Marshall McLuhan as its "patron saint". ''Wired'' went on to chronicle the evolution of digital technology and its impact on society. ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Computer Aided Design
Computer-aided design (CAD) is the use of computers (or ) to aid in the creation, modification, analysis, or optimization of a design. This software is used to increase the productivity of the designer, improve the quality of design, improve communications through documentation, and to create a database for manufacturing. Designs made through CAD software are helpful in protecting products and inventions when used in patent applications. CAD output is often in the form of electronic files for print, machining, or other manufacturing operations. The terms computer-aided drafting (CAD) and computer aided design and drafting (CADD) are also used. Its use in designing electronic systems is known as ''electronic design automation'' (''EDA''). In mechanical design it is known as ''mechanical design automation'' (''MDA''), which includes the process of creating a technical drawing with the use of computer software. CAD software for mechanical design uses either vector-based graphics t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
