Philadelphia
Philadelphia, often called Philly, is the largest city in the Commonwealth of Pennsylvania, the sixth-largest city in the U.S., the second-largest city in both the Northeast megalopolis and Mid-Atlantic regions after New York City. Since 1854, the city has been coextensive with Philadelphia County, the most populous county in Pennsylvania and the urban core of the Delaware Valley, the nation's seventh-largest and one of world's largest metropolitan regions, with 6.245 million residents . The city's population at the 2020 census was 1,603,797, and over 56 million people live within of Philadelphia. Philadelphia was founded in 1682 by William Penn, an English Quaker. The city served as capital of the Pennsylvania Colony during the British colonial era and went on to play a historic and vital role as the central meeting place for the nation's founding fathers whose plans and actions in Philadelphia ultimately inspired the American Revolution and the nation's inde ...

Mathematics
Mathematics is an area of knowledge that includes the topics of numbers, formulas and related structures, shapes and the spaces in which they are contained, and quantities and their changes. These topics are represented in modern mathematics with the major subdisciplines of number theory, algebra, geometry, and analysis, respectively. There is no general consensus among mathematicians about a common definition for their academic discipline. Most mathematical activity involves the discovery of properties of abstract objects and the use of pure reason to prove them. These objects consist of either abstractions from nature orin modern mathematicsentities that are stipulated to have certain properties, called axioms. A ''proof'' consists of a succession of applications of deductive rules to already established results. These results include previously proved theorems, axioms, andin case of abstraction from naturesome basic properties that are considered true starting points of ...

Pen-based
Pen computing refers to any computer user-interface using a pen or stylus and tablet, over input devices such as a keyboard or a mouse. Pen computing is also used to refer to the usage of mobile devices such as tablet computers, PDAs and GPS receivers. The term has been used to refer to the usage of any product allowing for mobile communication. An indication of such a device is a stylus or digital pen, generally used to press upon a graphics tablet or touchscreen, as opposed to using a more traditional interface such as a keyboard, keypad, mouse or touchpad. Historically, pen computing (defined as a computer system employing a user-interface using a pointing device plus handwriting recognition as the primary means for interactive user input) predates the use of a mouse and graphical display by at least two decades, starting with the Stylator and RAND Tablet systems of the 1950s and early 1960s. General techniques User interfaces for pen computing can be implemented in sev ...

Lotus Development Corporation
Lotus Software (called Lotus Development Corporation before its acquisition by IBM) was an American software company based in Massachusetts; it was "offloaded" to India's HCL Technologies in 2018. Lotus is most commonly known for the Lotus 1-2-3 spreadsheet application, the first feature-heavy, user-friendly, reliable and WYSIWYG-enabled product to become widely available in the early days of the IBM PC, when there was no graphical user interface. Much later, in conjunction with Ray Ozzie's Iris Associates, Lotus also released a groupware and email system, Lotus Notes. IBM purchased the company in 1995 for US$3.5 billion, primarily to acquire Lotus Notes and to establish a presence in the increasingly important client–server computing segment, which was rapidly making host-based products such as IBM's OfficeVision obsolete. On December 6, 2018, IBM announced the sale of Lotus Software/Domino to HCL for $1.8 billion. History Lotus was founded in 1982 by partners Mitch ...

TK/Solver
TK Solver (originally TK!Solver) is a mathematical modeling and problem solving software system based on a declarative, rule-based language, commercialized by Universal Technical Systems, Inc. History Invented by Milos Konopasek in the late 1970s and initially developed in 1982 by Software Arts, the company behind VisiCalc, TK Solver was acquired by Universal Technical Systems in 1984 after Software Arts fell into financial difficulty and was sold to Lotus Software. Konopasek's goal in inventing the TK Solver concept was to create a problem solving environment in which a given mathematical model built to solve a specific problem could be used to solve related problems (with a redistribution of input and output variables) with minimal or no additional programming required: once a user enters an equation, TK Solver can evaluate that equation as is—without isolating unknown variables on one side of the equals sign. Software Arts also released a series of "''Solverpacks''" ...

VisiCorp
VisiCorp was an early personal computer software publisher. Its most famous products were Microchess, Visi On and VisiCalc. It was founded in 1976 by Dan Fylstra and Peter R. Jennings as Personal Software, and first published Jennings' Microchess program for the MOS Technology KIM-1 computer, and later Commodore PET, Apple II, TRS-80 and Atari 8-bit. In 1979 it released VisiCalc, which would be so successful that in 1982 the company was renamed VisiCorp Personal Software, Inc.. :* VisiCalc was the first electronic spreadsheet for personal computers, developed by Software Arts and published by VisiCorp. :* Visi On was the first GUI for the IBM PC. Bill Gates came to see Visi On at a trade show, and this seems what inspired him to create a windowed GUI for Microsoft. VisiCorp was larger than Microsoft at the time, and the two companies entered negotiations to merge, but could not agree on who would sit on the board of directors. Microsoft Windows when it was released included ...

Inventors
An invention is a unique or novel device, method, composition, idea or process. An invention may be an improvement upon a machine, product, or process for increasing efficiency or lowering cost. It may also be an entirely new concept. If an idea is unique enough either as a stand alone invention or as a significant improvement over the work of others, it can be patented. A patent, if granted, gives the inventor a proprietary interest in the patent over a specific period of time, which can be licensed for financial gain. An inventor creates or discovers an invention. The word ''inventor'' comes from the Latin verb ''invenire'', ''invent-'', to find. Although inventing is closely associated with science and engineering, inventors are not necessarily engineers or scientists. Due to advances in artificial intelligence, the term "inventor" no longer exclusively applies to an occupation (see human computers). Some inventions can be patented. The system of patents was established t ...

Apple II
The Apple II (stylized as ) is an 8-bit home computer and one of the world's first highly successful mass-produced microcomputer products. It was designed primarily by Steve Wozniak; Jerry Manock developed the design of Apple II's foam-molded plastic case, Rod Holt developed the switching power supply, while Steve Jobs's role in the design of the computer was limited to overseeing Jerry Manock's work on the plastic case. It was introduced by Jobs and Wozniak at the 1977 West Coast Computer Faire, and marks Apple's first launch of a personal computer aimed at a consumer market—branded toward American households rather than businessmen or computer hobbyists. ''Byte'' magazine referred to the Apple II, Commodore PET 2001, and TRS-80 as the "1977 Trinity". As the Apple II had the defining feature of being able to display color graphics, the Apple logo was redesigned to have a spectrum of colors. The Apple II is the first model in the Apple II series, followed by Apple ...

WPS-8
WPS-8 is a Word Processing System sold by Digital Equipment Corporation for use with their PDP-8 processors (including the VT78, VT278 DECmate, and PC238 DECmate II and PC24P DECmate III microcomputer systems). WPS-8 supports a variety of 24 row by 80 or 132 column terminals including the VT52 family as well as the VT100 family and all subsequent ANSI-compatible terminals. A series of hierarchical menus allow the user to command the system; the particular style of these menus became very-widely used by Digital, particularly within their "ALL-IN-1" office system. Once a document is opened for editing, near WYSIWYG editing is provided using a ruler to indicate the text alignment and tab stops for any given portion of the text. A typical editing session might look like this: Text conformed to the preceding ruler (now offscreen). ----L----T-----------------------------T---------------------------------------------R---- Text conformed to the ruler shown just above L -> ...
