James T. Russell and the Invention of the Compact Disc
James Russell was born in Bremerton, Washington in 1931. His first
invention, at six years old, was a remote-control battleship with a
storage chamber for his lunch. In 1953, he earned his Bachelor of Arts
in physics and graduated from Reed College in Portland. Afterwards he
went to work as a Physicist in General Electric's nearby labs in
Richland, Washington. There he started many experimental
instrumentation projects. He was one of the first to use a color TV
screen and keyboard with a computer. He designed and built the first
electron beam welder.
When the Bettelle Memorial Institute opened its Pacific Northwest
Laboratory in Richland, Washington, James joined as a Senior
Scientist. Whilst attending he introduced his thoughts about optical
data storage. He started constructing prototypes of a
digital-to-optical recording and playback system and dispersing
information about the potential of this technology. He found more
interest in this work outside of the company though, so he joined a
firm and developed his ideas as vice president for research and member
of the board. Here he designed the system architecture for an audio
player and directed the development of the hardware and the storage
media.
During this time, James listened to a lot of music and was always
frustrated by the wear and tear of his phonograph records. He was also
unsatisfied with their sound quality. So, one Saturday while he was
home alone, he started sketching out a better music recording system.
James wanted a system that would record and replay songs without
physical contact between its parts, ...

... so the CD lasts longer. From the CD, came the CD-ROM, CD-I
(an interactive CD that's used to store video, audio or data), CD-ROM
XA (a CD that contains computer data, compressed audio data, and
video/picture data) photo and video CDs, CD-R (a writeable CD that can
only be written to once), and the CD-RW (a re-writeable CD that can be
written many times). We can now store our own music, documents, and
other files onto a disk, which is seen in both good and bad ways, but
either way, the CD has brought a lot more convenience to our present
world.

Penguin Publishing House, 1987 , Pearce Fred Acid Rain. What is it and
what is it doing to us?
A year later he opened his first industrial laboratory, where he would conduct several different experiments. His next major invention was the Quadruplex telegraph for Western Union, which was capable of transmitting two signals in two directions on a single wire. Jay Gould, the railroad industrialist, bought the rights of the telegraph and offered Edison a sum of $100000 dollars for his invention.
The gas mask, ever wondered who invented it? If not, then what about the traffic light? Well, Garrett A Morgan invented both of them. You may not have heard of him simply because Morgan been buried under and never spoken of simply because Morgan was a minority back when racism and sexism were extremely common. So they basically never talked about him inventing anything, and now not many people know about him. Both of his inventions are one of the greatest inventions to date.
During the late 1800’s, there was a time of great change. This was near the end of the industrial revolution in America. Some of the greatest inventions were invented during this time. We still use most of the inventions today, they are just modified to fit the needs of America today. 3 of the major inventions and innovations that came out of this time were the telephone, typewriter, and the incandescent light bulb.
data inside documents as well as to files and folders, and can also call up
The radio revolutionised the way families spent time together and receive information. The movie theaters had an impact on how people forgot about the depression and made life seem better. Many homes in the 1920s also just got access to electricity while many homes were still lit by candle light, but became more prominent as the time period continued. Labor saving appliances of the 1920s made the household chores easy to accomplish than it used to be. The 1920s was enriched by many technological achievements that helped changed the way americans communicated, managed their health, and partook in leisurely activities.
Playstation One of the biggest giants in the video game world today is Sony and their revolutionary Playstation. Right now their Playstation 3 is in circulation throughout the world, but prior to last year there was the original Playstation, and Playstation 2. This was the first video game system that used CD’s as disks for their games, instead of the usual cartridges used by Nintendo, Sega, Atari, and many other companies. It started off as a collaboration with Sony and Nintendo in 1988, trying to create an extension to Nintendo’s console called the Super Disk, since most companies were about to start making systems that way, and it was also much cheaper to create. Nintendo figured out that Sony would get all of the rights to their games so they split apart and did not finish creating the new addition.
During the second industrial revolution in the late 1800's, mass production and manufacturing of goods began to rapidly expand. With these changes also came a change in fuel sources, which began moving towards more modern forms such as petroleum and electricity. With theses changes in production and power came new possibilities and ideas. Many great thinkers became invested technological advancement by leveraging the changes that came with the second industrial revolution. Thomas Edison came to be one of America's greatest inventors during this time. While working on a way to record telegraph messages using paper indentations, Thomas Edison came up with the idea that conversation held over telephone may be able to be recorded in a similar fashion. On Nov. 21, 1877, Thomas Edison publicly announced that he had invented a device that can record sound: The Phonograph. This invention would have a major impact around the globe at the time and to this day is the foundation for not only recorded telephone messages, but all forms of recorded audio.
Fuji Film and Kodak are industry leaders that have been common household names for more than a decade. Each company's web page (fujifilm.com and kodak.com) provides extensive time lines reflecting the history, development and growth of their global empires that would intrigue both avid and novice photographers alike. By comparison the companies may appear to be identical, however, there are proportionately vast differences in their approach to profitability, market adaptation, as well as their overall management ethics.
As early as 1600 to present day 2012, electricity is being used for the most simplest objects to the most complicated gadget‘s. Today people take electricity for granted simply by just leaving a house light on. Whereas back in the 1600’s a candle was the main source of light. In 1600, a English scientist by the name of William Gilbert was the first person to use the term Electricity. He also wrote about the electrification of many substances. With William Gilbert’s success, many scientist have followed his foot steps which led to the great inventions that we have today. Scientists like Benjamin Franklin, Thomas Edison and Alexander Graham Bell have proved and invented many creations that without, humanity would be lost. Benjamin Franklin proved that electricity and lightning are the same and from this he made the lightning rod, which protects buildings and bridges from lighting damage. Alexander Graham Bell invented the telephone and without this invention communication would lack in today’s society. Thomas Edison was the most productive electrical explorer. He invented the light bulb in 1879 and many other products electricians use or install today. With Edison’s invention, about 499 billion kilowatts-hour are used today for lighting in residential and commercial areas. Electricity is used everywhere throughout our house and every part of our life and without electricity we would still be living in the 1600’s. The discovery of electricity has effected the human experience immeasurably, without the discovery of electricity humans would be deprived of telephones, cars and computers which would cause our lives to be completely different.

2. To transfer files from one computer to another (the files may be text, images, audio, video, etc.).
A hard drive or otherwise known as a hard disk is a storage device that contains one or more inflexible, circular platters that use magnetic particles to store data, instructions, and information. The system unit on most personal computers contains a least one hard disk, sometimes called an internal hard disk because it is not portable (Shelly and Vermaat). In other words a hard drive is the location in a computer where all the computer programs and files are stored. The hard drives are classified as random access, digital, magnetic, and data storage devices.
The History of Sound Recording The methods used to produce, edit, and record music and sound have changed with the introduction of new sound technology. The compatibility of computer technology with music recording has led to large scale developments in computer-based systems, especially by home users. Modern computer technology in music and audio is fundamentally different in comparison to older magnetic tape recording techniques because it is digital. New computerised digital methods are significantly better at manipulating sound (editing, recording, etc) than the highest fidelity analogue tape methods of the past.
The rise of technology came with a spark that would mark the creation of things that would make our lives simpler. These new ideas, or inventions as they were called, would shape our lives by making the tasks that we struggle with a possibility. Technology has its ups and downs, but overall it truly helps us for the better. Although many people may not agree that the tape recorder is one of the most important, I believe that is has had one of the most impacts on our society.
The invention of the telephone was approximately 120 years ago. It can be considered one of the best inventions in the world. This device was created in 1871 and uses electrical signals to allow sound to travel long distances. It has changed and evolved from the first telephone that was based on the telegraph to nowadays where we have smart phones.
