I. “What hath God wrought?” This message, the first of its kind to be send instantly over a long distance was transmitted back in 1844. While it may seem insignificant, this series of clinks was what started the ear od communication. Morse code is a system created by Samuel F. B. Morse that uses dits and dahs sent over an electromagnetic box to relate messages. Throughout its growth, it has aided in many wars and led to new inventions like the radio and telephone.
VPL was the first company that developed and sold some of the first virtual reality gear such as dataglove(developed along with Thomas Zimmerman) and Eyephone HMD. Eyephone 1 was sold for $9400, Eyephone HRX for $49000 and dataglove for $9000. In 1992 the first virtual reality related movie "The Lawnmower Man"was released. It was partly based on the life of Jaron Lanier. In 1995 "Nintendo virtual boy" was released in North America and Japan.
1845: Elias Howe invented a new type of sewing machine. It stitched on both sides of the material. 1839: An Austrian tailor Josef Madersperger designed several machines during the early 1800’s including a machine to sew caps. He worked on building it but failed. 1830: A French man named Barthelemy Thimonneir was able to convince people about the usefulness of the machine and made a batch of machines to make uniforms for the French army.
He did this with the help of a friend who had given him a clock, which he disassembled for the purpose of learning about the way it functions. With what he found out, he built a different clock, as mentioned above and earned fame. It also helped him learn more about math (Benjamin Banneker (1731-1806), n.d., p. xx) ("Mathematician and Astronomer Benjamin Banneker Was Born," n.d.) ("Benjamin Banneker (1731-1806)," n.d.). Another significant thing he did was that Banneker predicted a solar eclipse using the knowledge which he had taught himself with. This happened in 1789 and because of it, he showed other mathematicians and astronomers their errors in predictions("Mathematician and Astronomer Benjamin Banneker Was Born," n.d.).
III-Biography of writer: Harry Lillis Crosby, also known as Bing Crosby, was born in Tacoma, Washington in 1903. As a kid, people used to call him Bingo, therefore the name Bing was generated once he became famous. According to research, Bing was the most popular and influential media star of the first half of the 20th century. Crosby became a radio star in the late 1920s and early 1930s, first as a touring member of the Rhythm Boys and then as a solo act. He had solo hits in 1931, 1932, 1933, 1934, 1936 and 1937, but the peak of his career didn 't even occur until World War II, when he also became a bona fide film star.
Becoming a professor at Boston University one year later, he taught speech and vocal physiology. This is when Bell began to experiment with “transmitting several telegraph messages simultaneously over a single wire and also with various devices to help the deaf learn to speak, including a means of graphically recording sound waves,” according to History.com Staff. It wasn’t until 1874 that Bell actually began to form the idea of the telephone. Two years later on on March 7, 1876, he was granted a patent for his idea (History.com). The telephone changed the dynamics of the world from that point
I was trying to find a way to be able to record telegraphic messages by using tape. I had experimented with a diaphragm that contained a metal cylinder with tin foil wrapped around it. I had succeeded and created the phonograph, this device is able to play
Alexander Graham Bell lived March 3, 1847 – August 2, 1922. He was a was a scientist, inventor, engineer and innovator, and credited with patenting the first practical telephone. Although his invention of the telegram is his most famous accomplishment, Bell also worked with the deaf, and ( made invented other stuff). Alexander Graham Bell was born in Edinburgh, Scotland, on March 3, 1847. he was born just Alexander Bell; he did not receive his middle name until his eleventh birthday after begging his father to give him one. Alexander was the second of three sons of Alexander Melville Bell and Eliza Grace Symonds Bell.
Robert Hooke was encourage by his father to become a clockmaker or an artist as a career (Famous). He had amazing skills in building clocks, sundials and model ships (Learnodo).When his father died in 1648, 13-year-old Robert went to London to work will and assist the amazing painter Peter Lely. Shortly after going to london to work with Peter, he ended up stop working with
V.I Pudovkin said that, “the foundation of film art is editing.” (Giannetti 2001:133) Early editing dates back to the late 1800’s. What became known as the Silent Period, 1885-1930, saw immense experimentation and new ideas blossom in terms of film editing which developed as different visionary individuals who still influence how we edit today, shaped it. Dancyger (2011:3) states that the first motion pictures date back to 1895, and editing was minimal if not non-exist. These films were about one minute in length. The cameras were placed without screen direction or compositional considerations and even lights were a variable.
The last official Brownie cameras made were "anniversary model", 110 film models in the early 1980s. Beau Brownie The Beau Brownie range was available from 1930 to 1933. They differed little from the popular Brownie cameras, the only technical difference being the introduction of a new doublet lens, allowing the same picture to be projected on a film plate over a shorter distance, making the Beau Brownies nearly 2" shorter than their conventional counterparts. Visually, they had a different enameled two-tone front plate in a geometric Art Deco design, the work of American designer Walter Dorwin Teague. They were available in five color combinations: black and burgundy, brown and tan, two-tone blue, two-tone green, and two-tone rose.
Please refer to Statistics assignment seven to see the SPSS output for the Chi-Square tables. Step 5: Degrees of freedom The degrees of freedom (df) for a Chi-Square for independence is calculated as the number of rows subtracted by one multiplied by the number of columns subtracted by one (Salkind, 2013). From the SSPS output in assignment seven outline there are two rows and 4 columns. df = (Rows-1) (Coloums-1) df= (2-1)(4-1) df= (1)(3) df= 3 Therefore, the degree of freedom (df) is 3. Step 6: Critical
He would later on establish his own printing shop. When opening his printing shop he published his successful paper “Poor Richard’s Almanac”. Shortly after his printing press business had expanded throughout the colonies. It was such a success that Franklin could retire at the age of 42. He then would take the time that he had now to pursue his fascination of science.
I saw a statistic which says that 95 percent of what we know about the human brain has been learned in the last ten years. Science is just beginning to understand how the most complicated organ in the human body functions. Neuroscientists now have the technology to observe the brain in action through the recent development of brain imaging technology. Dr. Richard Restak produced a five part series for PBS called The Secret Life of the Brain and he has also written a book with the same title. From the episode on the adult brain, he reaches the following conclusion - "we are not thinking machines, but rather feeling machines that think".
Philo Farnsworth, the creator, had ideas about how to create the first television since he was 14-years-old. His goal for the television system was to have a system that could show 400 lines per frame (Landen, 2009). This first television camera tube was named the “Image Dissector”, “which would dissect an image line-by-line with a pulsating electrical charge and then transmit these elements”. The receiver for the television was built by using a chemistry flask, which Phil called the “Image Oscillite”. In order to rid the blurry picture, the “sawtooth” waveform was created.
