A major breakthrough in internet availability as far as occupants of rural areas are concerned is the use of satellites to provide internet access. People who live too far from a phone system junction to receive DSL and who also have no cable lines running through their areas now have a new option. Satellite internet is also a great source of excitement among those longing for a better solution for portable internet connections than their cell phone. Anyone on the move a lot and cannot rely on a ground line to maintain the contact with the world wide web can now turn to space in order to access all the internet provides.
Satellites that provide internet access operate in much the same way as those that provide television services. The orbiting satellite receives or sends a signal through a dish that is connected to a PC or Mac. The information is then represented on the screen. Satellite internet download speed is slower than available through cable or DSL, but the modem speed is usually ten times faster than landline methods. Users of satellite internet must also have a clear southward view for their dish, as the satellites used for internet technology have their orbit above the equator. As with satellite television, satellite internet transmission can sometimes be interrupted by storms or trees.
Satellite internet also offers a huge advantage in terms of bandwidth limitations. The technology used for satellite internet is called Internet Protocol multicasting, which means up to 5,000 channels of information can be served simultaneously by one satellite. IP multicasting sends data from one point to many points by sending data in compressed format. Compression reduces the size of the data and the bandwidth. Usual dial-up land-based terrestrial systems have bandwidth limitations that prevent this immense amount of multicasting.
Satellite internet is an ideal innovation for those who otherwise would find themselves isolated from the information age through their remote locations.
Music Science Fair Projects
Students and adults alike might be surprised that an interest in music and participation in a science fair can be combined. Music science fair projects are some of the most interesting demonstrations at the school event. Most people enjoy some style of music in their car, at home, with a personal music player, in a band, or at concert. Many people enjoy singing in a choir. What all these venues have in common is obviously music. What most participants do not realize is that there is science at work in every note they play, sing or hear! Music science fair projects offer the students and the visitors to the event to learn completely new concepts of science as they relate to music. Many of these people will leave the event with a deeper level of understanding of and appreciation for the magical science that is music!
Music science fair projects are chosen by students who have a love of the universal language that we all call music. The most creative students will choose music science fair projects to investigate the various topics surrounding the production and enjoyment of music. The first category of music science fair projects will focus on different ways to produce the tones that human being consider musical. This may include an investigation of the sounds of music from different cultures. Included in this are the unique instruments found around the world. Additionally, this may investigate the rhythms that different cultures gravitate toward. These types of music science fair projects will also demonstrate the creativity of students as they develop their own mechanisms for making musical tones. The most popular of these are crystal containers filled with various depths of water.
The other group of students presenting music science fair projects may focus on the effects that music has on people. Instead of examining the instruments, these students will explore the old adage that music hath charms to sooth the savage breast. There are still research studies being conducted on the soothing effects of music on various demographics of people as well as different animal and plant life. These students who present demonstrations and research findings on this data also increase everyones understanding and appreciation for the universal language of music.
