ENIAC( Electronic Numerical Integrator And Computer) was the first general-purpose electronic computer. It was a Turing-complete digital computer capable of being reprogrammed to solve a full range of computing problems.^]

ENIAC was designed to calculate artillery firing tables for the United States Army’s Ballistic Research Laboratory. When ENIAC was announced in 1946 it was heralded in the press as a “Giant Brain”. It boasted speeds one thousand times faster than electro-mechanical machines, a leap in computing power that no single machine has since matched. This mathematical power, coupled with general-purpose programmability, excited scientists and industrialists. The inventors promoted the spread of these new ideas by teaching a series of lectures on computer architecture.

The ENIAC’s design and construction was financed by the United States Army during World War II. The construction contract was signed on June 5, 1943, and work on the computer began in secret by the University of Pennsylvania’s Moore School of Electrical Engineering starting the following month under the code name “Project PX”. The completed machine was announced to the public the evening of February 14, 1946 and formally dedicated the next day at the University of Pennsylvania, having cost almost $500,000 (nearly $6 million in 2010, adjusted for inflation). It was formally accepted by the U.S. Army Ordnance Corps in July 1946. ENIAC was shut down on November 9, 1946 for a refurbishment and a memory upgrade, and was transferred to Aberdeen Proving Ground, Maryland in 1947. There, on July 29, 1947, it was turned on and was in continuous operation until 11:45 p.m. on October 2, 1955.

ENIAC was conceived and designed by John Mauchly and J. Presper Eckert of the University of Pennsylvania.^[9] The team of design engineers assisting the development included Robert F. Shaw (function tables), Chuan Chu (divider/square-rooter), Thomas Kite Sharpless (master programmer), Arthur Burks (multiplier), Harry Huskey (reader/printer) and Jack Davis (accumulators).

Qatar astronomer Dr Khalid Al Subai has become instrumental in the discovery of a new alien planet, working in collaboration with scientists from the UK and the US. This hot Jupiter, now named Qatar-1b, adds to the growing list of alien planets orbiting distant stars, or exoplanets.

Qatar-1b is a gas giant 20 percent larger than Jupiter in diameter and 10 percent more massive. It belongs to the hot Jupiter family because it orbits 3.5 million km from its star – only six stellar radii away. The planet roasts at a temperature of around 1100 degrees Celsius.

Khalid, leader of the Qatar exoplanet survey and a research director at Qatar Foundation teamed up with scientists from Universities of St Andrews, Leicester and Keele in the UK and the Harvard-Smithsonian Center for Astrophysics (CfA) in the US to discover a new alien world.
Building on UK technology developed for the SuperWASP exoplanet survey, the St Andrews and Leicester teams worked with Al Subai to establish the computer systems used to process raw images from the Al Subai cameras, extracting and sifting through data from hundreds of thousands of stars.
The team has submitted their results to the journal Monthly Notices of the Royal Astronomical Society.
