Sketch of Nipkow 's 'electric telescope '
The boob tube, the idiot box, the telly, or more commonly known as the television began as just an idea. If we could send sound over waves of electricity in the air, why couldn 't we send pictures? Paul Gottlieb Nipkow was one of many men that sparked the race for television. In 1884 Nipkow introduced his mechanical scanning system. The device had an 'electronic telescope ' and a disc which was perforated with 20 square shaped holes arranged in a spiral. As the disk would spin, a strong light would shine through the holes and onto whatever was in front of the machine. A selenium photoelectric cell was used to translate the lines into an electrical signal. The result was a black and white picture with 20 lines. As you can imagine, the picture was not very clear. As a matter of fact, it could be quite terrifying. The RCA adopted the mechanical scanning process and it gradually became better as more inventors modified Nipkow 's design. One such inventor was John Baird. Baird 's mechanical system was pitted against young inventor Philo T. Farnsworth 's electronic television. Farnsworth was approached by the RCA in an attempt to buy the patents for his system from him as they had done with many companies. Farnsworth however managed to convince the RCA to license his patents which gave him control over his inventions and earnings in royalties from the RCA. Electronic television was quickly adopted as the standard for televisions by the RCA. Development of the electronic system continued well into the 1930s. The first television finally made its debut at the New York World 's Fair in 1939. By 1941, the FCC had adopted standards for operation through advisement...

...timate goal is to reduce the need for cables and cords and clutter on your entertainment center. However, in practice, the Smart TV doesn 't seem to be that smart. The interface is usually confusing and not practical for the common user. The television will become 'dumb ' overtime because they don 't receive regular updates like your Xbox or Playstation console would. New video services will become unusable and some apps aren 't available on all models of televisions produced by the same company. You would think that because you are bypassing regular television you would also be bypassing advertisement. But Samsung 's Smart TVs actually embedded extra ads into local media, granted it was only one ad every 20-30 minutes. However, there is an opt out feature on the televisions that had this embedded advertisement, the same kind of bologna that Windows is infested with.

- Space: up until a few centuries ago astronomers knew little about the universe outside of our planet. But now, with vastly improved technology, astronomers are able to uncover so much more about what lies outside of Earth. While today’s observational technology is greatly superior to that of the past, we can’t disregard the accomplishments of astronomers in the past, because without their work our knowledge of space would far less than it is today. From Galileo’s first telescope to the Webb space telescope that has yet to be launched, there are so many observational technologies that made important contributions to the observation and exploration of space....

- The Hubble Telescope is the world’s first space-based optical telescope. The Hubble telescope received its name from American astronomer Dr. Edwin P. Hubble. Dr. Hubble confirmed an ever expanding universe which provided the basic foundation of the Big Bang theory. The first concept of the Hubble telescope came from Lyman Spitzer in 1946 who at that time was a professor and researcher at Yale University, Professor Spitzer believed that Earth’s atmosphere blurs and distorts light and a space orbited telescope would be able to surpass this problem....

- There is a beckoning about space—an indefinable pull towards its airless environment. While I share a childlike excitement of zero gravity far off planets, I don’t lose myself in heavenly dreaming. Infact, what is more my fascination, is the technology that allows children to have their dreams, that allow them to grow up and actually touch the stars. And thus, I put forward for your enjoyment and enlightenment, a detail and profile of the most landmark instrument ever created for observation of the stars....

- Telescopes were one of the most important inventions in the science of astronomy. They opened up the sky, allowing people to see things previously invisible. With telescopes, scientists could look beyond the visible sky and learn about what exists past the night sky. From the earliest telescopes of Galileo’s age to the incredible telescopes used today, they have allowed people to see just how large the universe is and what makes up that universe. How the Telescope Opened the Universe When Galileo created his telescope and aimed it towards Jupiter, not only did he have the first view of something beyond the Earth, but his discovery proved that there was more to the night sky than the small p...

- The Light in A Sketch of the Past and Mrs. Dalloway Virginia Woolf's method to writing fiction was always to "dig out beautiful caves1" behind, within, and around her characters - to tunnel through their consciousness in order to tell their story as artfully as one tells his or her own. It is her "tunneling" process that makes her style so distinctive: her sentences layered with multiple meanings, her paragraphs rich with stream-of-consciousness internal monologue, and her dialogue sparse. Clearly, she had few qualms about taking the modern novel's all-too-common, linear form of storytelling and turning it upside down in order to dig through to its core - its very essence - and fi...

- Here you will find a variety of information on the optical characteristics of various types of telescopes as well as some of the basic underlying physics behind them. This includes some information that pertains to the preformance degredation of a telescope optical system (for instance, vignetting and air turbulance) and a few concepts of mirror design (the parabolic shape and over/under correction of the primary mirror). I'd recommend starting with the "Optical Paths" section so you can familiarize yourself with some of the basic types and concepts of several of the widely used telescope designs before reading the other sections....

- The Hubble Space Telescope is one of the most amazing machines in orbit right now. In 1946, an astrophysicist named Dr. Lyman Spitzer proposed that a telescope in space would reveal better and clearer images that are even far from earth than any ground telescope. This idea was very extravagant because no one had yet launched a rocket into outer space. As the US space program excelled quickly over the early years, Spitzer lobbied NASA and Congress to develop a space telescope. In 1975, the European Space Agency and NASA began to develop the telescope that would change astronomy for ever.... [tags: Nasa Space Hubble Telescope]

- The Hubble Telescope is a low-orbit telescope in the high Earth atmosphere. The fathers of modern rocketry, Hermann Oberth, Robert Goddard, and Konstantin Tsiolkovsky published The Rocket into Planetary Space, in 1923, which mentioned sending a telescope to space for one of the first times in history. The purpose of the telescope was to provide sharper images for astronomers to study. While much larger telescopes reside on Earth, the pictures that the Hubble Telescope sends back are much better because the telescope is above the interference caused by the atmosphere....

- Telescope Light and other kinds of electromagnetic radiation coming from the universe outside the Earth must travel enormous distances through space and time to reach observers. Only the brightest and nearest stars can be seen with the unaided eye. To see farther and to clarify and measure what is seen, a telescope is needed. The word telescope is derived from the Greek words tele, "from afar," and skopos, "viewer." Even a simple homemade telescope can clearly show Saturn's rings, Jupiter's bands and red spot, stars, nebulae, and nearby galaxies not visible to the unaided eye.... [tags: science]

- The telescope has changed the world greatly by being able to make distant objects appear closer and more distinct. It helped scientists to discover things that could not be seen by the naked eye. For example, a lot of things in space would have not been discovered if it were not for the telescope. Also, it helped the world of eyesight. It would not only let you see objects from far away, it would also help you see if you had a problem with it. It could also be used for other things: hunting, war, and making new discoveries....
