"Dr. Mauchly's initial studies on weather prediction drew him to computing.
In 1936, he was doing painstaking, protracted research on how sunspots might affect the weather." Unfortunately, there are zero sunspots at the start of the third millennium, hence any calculated correlation would be zero. John William Mauchly: The Brain Behind The Giant Brain:?Part 1 Tuesday, March 24, 2009 Dr. Rocco L. Martino, For The Bulletin Editor's Note: This is the second in a series to run each Tuesday. Wikipedia, the Free (Internet) Encyclopedia, in its description of the Electronic Numerical Integrator and Computer ENIAC, contains the following history: "In 1942 [Dr. John William] Mauchly wrote a memo proposing the building of a general-purpose electronic computer. The proposal, which circulated within the Moore School (but the significance of which was not immediately recognized), emphasized the enormous speed advantage that could be gained by using digital electronics with no moving parts. Lieutenant Herman Goldstine, who was the liaison between the United States Army and Moore School, picked up on the idea and asked Mauchly to write a formal proposal. In April 1943, the Army contracted with the Moore School to build the ENIAC. Mauchly led the conceptual design while [Dr. John Presper] Eckert [Jr.] led the hardware engineering on ENIAC. A number of other talented engineers contributed to the top-secret project 'PX.' "Because of its high-speed calculations, ENIAC could solve problems that were previously unsolvable. It was roughly a thousand times faster than the existing technology. It could add 5,000 numbers or do fourteen 10-digit multiplications in one second. "ENIAC could be programmed to perform sequences and loops of addition, subtraction, multiplication, division, square-root, input/output functions, and conditional branches. Programming was initially accomplished with patch cords and switches, and reprogramming took days. It was redesigned in 1948 to allow the use of stored programs with some loss in speed." Dr. Mauchly was born on Aug. 30, 1907 in Cincinnati, Ohio. Even as a young boy, he strove to understand how things worked. A natural tinkerer, he took apart locks and studied the components of telephones. Climbing into a telephone company ditch outside his home in Chevy Chase, Md., he would hook up wires from the trunk line to his room, and even fashioned an intercom system for his pals. To read past his bedtime, he furtively placed a sensor under the steps leading to his room, alerting him of his parents' approach. His curiosity for electricity was in his blood, as his dad, Sebastian J. Mauchly, worked with the Terrestrial Electricity and Magnetism section at Washington, D.C.'s Carnegie Institute, devising gear to measure electrical fields over land and water. As a high school student, recalled Dr. Mauchly's future wife, Kathleen "Kay" McNulty, he worked nights and weekends helping his father with scientific calculations. At Baltimore's John Hopkins University, Dr. Mauchly started out as an engineering major but, wishing to see "the big picture," moved over to physics and graduated with a doctorate at age 25. Although the Great Depression was in full swing, he was offered an associate professorship of physics at small Ursinus College, 25 miles from Philadelphia, for $3,800 a year. Dr. Mauchly's initial studies on weather prediction drew him to computing. In 1936, he was doing painstaking, protracted research on how sunspots might affect the weather. With funds from President Franklin D. Roosevelt's National Youth Administration, he employed students to pour through the Carnegie Institution's mammoth collection of atmospheric observations. But sorting through the data by hand, or even with punch cards, would have taken decades. This drove Dr. Mauchly to find ways of simplifying and speeding up his calculations. He knew the limiting factor for timely weather prediction was calculations - the mathematical tabulation of temperature, wind and precipitation data required to make accurate predictions fast enough to be useful. It is worthless, after all, to predict today's weather tomorrow. Archives at the University of Pennsylvania reveal that Dr. Mauchly began dreaming of a machine to do the work of a mechanical calculator, but automatically, with electronic switches for retrieval and storage, and electronic tubes to do math at speed-of-light pace. His concept was a fully electronic machine with no moving parts that would take a problem from beginning to end without intermediate recording and then re-entering of any number as must be done with any machine that has no memory capability. In the mid-1930s, he set along the path of creating such a machine by building counting devices by hand, using parts he acquired with his own money from secondhand stores. Dr. Mauchly knew that scientists had recently devised electronic instruments for counting cosmic rays. The challenge was recording hundreds of "cosmic events" per second, a rate that overwhelmed electromechanical recorders. In response, physicists came up with so-called scaling circuits using high-speed vacuum tubes to bring the pulses down to a manageable number. As one writer puts it: "When, say, eight events struck the sensors, the first set of circuits dispatched four electrical pulses to the second set, which sent two pulses to the third ring, which in turn issued a single pulse to the recorder." Dr. Mauchly was to apply such circuits to his electronic calculator. Invention is often a solitary, even artistic, task. For example, Mozart once stated he would go for a long walk, and new music would begin circulating in his mind. Then he would write the music out as his mind dictated it. Einstein also spoke of invention as a form of art, and referred to other great scientists as artists. He spoke of conceiving his notions of relativity by imagining that he was traveling along a light beam traveling through space. In similar fashion, Dr. Mauchly conjured up most of the logic behind the first digital, general-purpose computer as he imagined the ideal way to perform tedious calculations. While he certainly had knowledge of electronics, he knew that he needed a partner in his quest who was a gifted specialist in circuits and electronics. In 1941, he found such a partner in Dr. Eckert, with whom he teamed to produce not only the first ever electronic computer, ENIAC, but also the first production machine, UNIVAC. While Dr. Mauchly was the conceptual genius who "traveled the light beams of space," Dr. Eckert was the gifted genius who could make music from wires and tubes. The physicist and the engineer made history. Together they dreamed, worked, designed, built teams, built computers and changed the world forever. To a creative thinker like Dr. Mauchly, the construction of devices and systems took place through a process akin to composing a poem. Poetry is an economical, harmonious assembly of words directed to a desired purpose or theme. The poet needs to know how to fit together many complex pieces to create a compelling whole. In a similar way, Dr. Mauchly envisioned the solution to an intricate puzzle, and set about making the right pieces to fit within the solution. Dr. Rocco Martino is the founder and CEO of CyberFone Technologies and a pioneer in the computer industry. He knew and worked with both of the inventors of ENIAC. He is completing a book on the history of the computer entitled Innovation: From ENIAC to the Cyber Age. |
