- 2281: History of Computers
- ... automatic, it was controlled by instructions punched into a roll of paper tape. There was a need for an all-electronic machine. This project was taken up by Dr. J. Presper Eckert Jr., and Dr. John W. Mauchly, with help from a few of their colleagues, in the spring of 1946. For two and a half years, they work diligently to construct a machine called the Electronic Numerical Integrator and Calculator ... a room the size of an average three-bedroom home. ENIAC was capable of performing 5,000 additions in one second. At around the time ENIAC was being created, a man by the name of John Atanasoff was hung up on a problem: How do you get machines to remember stuff youve already done? In 1939 Atanstoff and a graduate student, Clifford Berry started on the project of making an ...
- 2282: The Birth Of Fiber Optics-To it's Popularity
- The Birth Of Fiber Optics-To it's Popularity In 1854, John Tyndall demonstrated to the Royal Society that light could be conducted through a curved stream of water, proving that a light signal could be bent. In 1880, Alexander Graham Bell invented his "Photo phone" which ... light images in an attempt at early television. In 1898, American David Smith applied for a patent on a bent glass rod device to be used as a surgical lamp. In the 1920's, Englishmen John Logie Baird and American Clarence W. Hansell patented the idea of using arrays of transparent rods to transmit images for television and facsimiles respectively. In 1930, German medical student, Heinrich Lamm was the first person ...
- 2283: Technological Advances In Agriculture Since The 1600's
- ... gathering and nomadic herding, to the complex farms of today which employ highly developed fertilization, irrigation, and cultivation systems, man has relied on technology, whether in the form of a spear and basket or a John Deere tractor, to assist him in his quest for food. History further records that the degree of agricultural productivity a society is afforded through technology is often a direct reflection upon the degree of civilization ... agriculture were seen to chronologically correspond with the development of the cotton gin. Charles Newbold made a significant advancement in agriculture in 1797 with his introduction of the cast-iron moldboard plow. The American blacksmith John Deere further developed the plow in the 1830's and manufactured it in steel ("Agriculture", Encarta 1999). English farmer Jethro Tull's invention of the seed drill in the early 1700's and Cyrus McCormick ...
- 2284: Understanding Computers
- ... still used today, and when in the right hands, can be used very accurately and quick. The next real important invention in computer history was a simple little thing called Napiers bones, made by John Napier in the 1600s it was just a bunch of bars or strips of bone with numbers printed on their face. by placing certain bones next to each other and at certain angles and ... the same all the way up until the 1970s this method was used for data processing and storage. The first computer that we may consider a real computer was a machine built by Dr. John W. Mauchly and J. Persper Eckert called ENIAC(Electronic Numerical Intergrator and Calculator.) This computer contained hundreds of vacuum tubes and its O/S(operating/System) that sends the codes on what to do to ...

- ... Mauchly at the University of Pennsylvania and asked him to develop a machine that would quickly calculate the trajectories for artillery and missiles. Mauchly and his student, Presper Eckert, relied on the work of Dr. John Atanasoff, a professor of physics at Iowa State University. During the late 30's, Atanasoff had spent time trying to build an electronic calculating device to help his students solve complicated math problems. One night ... a vacuum tube would then burn out once every 15 minutes. It would take on average 15 minutes to find the burnt out tube and replace it. Enthralled by the success of ENIAC, the mathematician John Von Neumann undertook, in 1945, a study of computation that showed that a computer should have a very basic, fixed physical construction, and yet be able to carry out any kind of computation by means ...
