Trinity (nuclear test) – Wikipedia

United States historic event

United States historic place

Trinity was the code name of the first detonation of a nuclear device. It was conducted by the United States Army at 5:29 a.m. on July 16, 1945, as part of the Manhattan Project. The test was conducted in the Jornada del Muerto desert about 35 miles (56 km) southeast of Socorro, New Mexico, on what was then the USAAF Alamogordo Bombing and Gunnery Range, now part of White Sands Missile Range. The only structures originally in the vicinity were the McDonald Ranch House and its ancillary buildings, which scientists used as a laboratory for testing bomb components. A base camp was constructed, and there were 425 people present on the weekend of the test.

The code name “Trinity” was assigned by J. Robert Oppenheimer, the director of the Los Alamos Laboratory, inspired by the poetry of John Donne. The test was

Gadget (computer science) – Wikipedia

In computational complexity theory, a gadget is a subset of a problem instance that simulates the behavior of one of the fundamental units of a different computational problem. Gadgets are typically used to construct reductions from one computational problem to another, as part of proofs of NP-completeness or other types of computational hardness. The component design technique is a method for constructing reductions by using gadgets.[1]

Szabó (2009) traces the use of gadgets to a 1954 paper in graph theory by W. T. Tutte, in which Tutte provided gadgets for reducing the problem of finding a subgraph with given degree constraints to a perfect matching problem. However, the “gadget” terminology has a later origin, and does not appear in Tutte’s paper.[2][3]

Computer intended for use by an individual person

A personal computer (PC) is a multi-purpose computer whose size, capabilities, and price make it feasible for individual use.[1] Personal computers are intended to be operated directly by an end user, rather than by a computer expert or technician. Unlike large costly minicomputers and mainframes, time-sharing by many people at the same time is not used with personal computers.

Institutional or corporate computer owners in the 1960s had to write their own programs to do any useful work with the machines. While personal computer users

Gadget – Wikipedia, la enciclopedia libre

Un gadget es un dispositivo que tiene un propósito y una función específica, generalmente de pequeñas proporciones, práctico y a la vez novedoso. Los gadgets suelen tener un diseño más ingenioso que el de la tecnología corriente.[1]

Se le ha dado el nombre de gadget o widget a una nueva categoría mini aplicaciones, las cuales fueron diseñadas para mejorar servicios, una aplicación, proveer información o cualquier tipo de interacción de un computador; esto se realiza a través del world wide web, por ejemplo una extensión de alguna aplicación de negocios, que nos provea información en tiempo real del estatus del negocio u organización.
Son comúnmente llamados gadgets a los dispositivos electrónicos portátiles como PDAs, móviles, teléfonos inteligentes, reproductores mp3, entre otros. En otras palabras, es una jerga electrónica.[2]

Inspector Gadget (film) – Wikipedia

1999 comedy film produced by Walt Disney Pictures

Inspector Gadget (also known as Inspector Gadget: The Movie and The Real Inspector Gadget in the working title) is a 1999 American science fiction action comedy film directed by David Kellogg and written by Kerry Ehrin and Zak Penn from a story by Ehrin and Dana Olsen. Loosely based on the 1983 animated television series of the same name, the film stars Matthew Broderick as the title character, Rupert Everett as Dr. Claw, Michelle Trachtenberg as Penny and Dabney Coleman as Chief Quimby. Three new characters were introduced such as Dr. Brenda Bradford (played by Joely Fisher), Mayor Wilson (played by Cheri Oteri) and the Gadgetmobile (voiced by D. L. Hughley). The film tells the story of how Inspector Gadget and Dr. Claw came to be. It was filmed in Pittsburgh, Pennsylvania; Baton Rouge, Louisiana; and Los Angeles, California with the ice

Computer science – Wikipedia

Study of the theoretical foundations of computation

Computer science deals with the theoretical foundations of computation and practical techniques for their application.

Computer science is the study of processes that interact with data and that can be represented as data in the form of programs. It enables the use of algorithms to manipulate, store, and communicate digital information. A computer scientist studies the theory of computation and the design of software systems.[1]

Its fields can be divided into theoretical and practical disciplines. Computational complexity theory is highly abstract, while computer graphics emphasizes real-world applications. Programming language theory considers approaches to the description of computational processes, while software engineering involves the use of programming languages and complex systems. Human–computer interaction considers the challenges in making computers useful, usable, and accessible.

Single-board computer – Wikipedia

A single-board computer (SBC) is a complete computer built on a single circuit board, with microprocessor(s), memory, input/output (I/O) and other features required of a functional computer. Single-board computers were made as demonstration or development systems, for educational systems, or for use as embedded computer controllers. Many types of home computers or portable computers integrate all their functions onto a single printed circuit board.

Unlike a desktop personal computer, single board computers often do not rely on expansion slots for peripheral functions or expansion. Single board computers have been built using a wide range of microprocessors. Simple designs, such as those built by computer hobbyists, often use static RAM and low-cost 8- or 16-bit processors. Other types, such as blade servers, would perform similar to a server computer, only in a more compact format.

A computer-on-module is a type of single-board computer made to plug into a carrier

Gadget – Wikipedia

A gadget is a small tool such as a machine that has a particular function, but is often thought of as a novelty.[1] Gadgets are sometimes referred to as gizmos.

History[edit]

The etymology of the word is disputed. The word first appears as reference to an 18th-century tool in glassmaking that was developed as a spring pontil. [2] As stated in the glass dictionary published by the Corning Museum of Glass, a gadget is a metal rod with a spring clip that grips the foot of a vessel and so avoids the use of a pontil. Gadgets were first used in the late 18th century. [3] According to the Oxford English Dictionary, there is anecdotal (not necessarily true) evidence for the use of “gadget” as a placeholder name for a technical item whose precise name one can’t
