The Future Of Wireless Technology

Wireless technology is gaining ground because of its low cost and ease-of-use. We all are familiar with radio and phones that use wireless technology. There are many more possible practical applications for wireless and the breakthrough developments happening in this field are set to revolutionize the future.

Wireless network means less maintenance and less cost. The advent of radio has put a stop to the use of telephones that uses wires to transmit signals. The new age cell phones based on wireless technology have made it possible for us to reach anyone anytime. Wireless technology translates into a lower cost since it obviates the laying down of cables and wires and regular maintenance. The other area where a significant impact has been felt is in the networking of computers. The usual scenario of having a wired Internet connection is all set to change. The wireless connections are soon going to be cheaper than the wired alternative and will also be easier to use. This will result in people shifting to the wireless option, if available.

Worldwide Interoperability for Microwave Access (WiMAX) will be the next generation of wireless, an improvement over the existing wireless networking that uses a standard called 802.11. The good news is that you will not need to change your equipment, as it will run on the existing hardware. Though scientists are still working on it, it is poised to take the world by storm. The first WiMAX equipment is slated for launch by the end of 2005. Its biggest advantage will be that it will cover a wide area, which could be as much as up to 50 kilometers! The term Local Area Network (LAN) will be replaced by Metropolitan Area Network (MAN), which would cover the whole city! It will also offer higher speeds of up to an astounding 10MB per second, coupled with improved security. All you would need to do is buy a subscription, plug into a network and you are ready to go!

Bluetooth technology is becoming a part of our lives now. Apart from replacing your USB port, it has the potential of replacing all the wires in your equipment, except for the power cord! Imagine the convenience of staying in a house that does not have wires, where Bluetooth connects all the equipment. It would mean fewer hassles in cleaning the house coupled with freedom from the fear of tripping over wires!

It wouldn't be surprising if by the end of the next decade wireless technology would becomes commonplace. It sounds convenient and should also be lesser in cost. Given its potential, we all seem to have a much easier life, with a faster and safer access to the world!

Fun Toys That Help Encourage Kids To Love Science

If you want your child to have a love for learning which lasts a lifetime, you should start encouraging them early. Kids have a natural tendency to want to explore their environment and discover the world around them. A great way to instille a love for learning and an interest in science, one of the best things you can do for you child is get them a science toy. There are a number of science toys out there designed to provoke your child's interest in learning and give them a better understanding of their environment.

One of the most popular science toys for children is the chemistry set. Chemistry sets range in price from around $20 to upwards of $200. As you can tell from such a price range, there is a wide variety of options when buying a chemistry set. The difference in price is usually due to the amount of equipment and chemicals included with the set. Many parents are concerned with their child's safety when experimenting with chemicals. As with most activities, a child should be supervised while playing with a chemistry set, but the chances of them blowing up the house or even seriously injuring themselves are pretty slim. Another concern parents have with chemistry sets is what to do when the chemicals are depleted. Again, this isn't a big deal because most sets come with catalogs from which you can restock the set for a reasonable price. You can also order refills online.

Another popular science toy is the ant farm. Who didn't have one of these when they were a kid? What you probably didn't know is that they have a more scientific-sounding name: formicarium. "Ant farm" is, in fact, a trademarked name owned by Uncle Milton Industries. Ant farms are highly educational and fun. Kits never come with ants. They instruct you to either collect some from around the house or you can have a small tube of them delivered to your house. Most come with some sort of sand or soil in which the ants build their tunnels. Newer models, though, come with a thick gel which the ants not only burrow through but they can also eat it.

A third toy which will encourage your child's interest in science is the microscope. Children can learn a great deal about the natural world with a microscope. There are a plethora of microscopes on today's market. The sky's the limit when it comes to pricing on these instruments, but they can also be found at very reasonable costs. You can buy a good microscope for around $40. Spending less will get your a pretty shoddy instrument. And if you want nothing but the best for your child then you can easily spend in excess of $700! Kids can find things all over the place to look at under a microscope and you can also buy them prepared slides. A set of 10 such slides will cost about $20 and have things to look at like bacteria, a sliver of leaf, and animal skin.

Recent news reports have stated that there aren't enough scientists being produced in America. Maybe your kid will be the next Einstein. It's got to be someone, right? Why not your kid? Encourage learning and an interest in science by giving your child a science toy.

The Imaginative World Of Gizmos

Out of all the genres of books that have been written, science fiction seems to be one that is a class apart. The feeling towards the genre is either one of fanatic following or extreme hatred. Those who have a natural penchant for unearthly objects and unsolved mysteries tend to get addicted at a relatively young age, which could be as young as 7 to 8 years. To appease the curiosity and desire to read more of such books, there are science fiction clubs that are formed where infatuated kids or teens exchange books and videos of their favorite science fiction books and movies.

One of the first science fiction books that one can remember today are The Time Machine and Journey to the Center of the Earth, by H. G. Wells. Today these favorites have been replaced with modern classical space operas like Robert A. Heinlein's Citizen of the Galaxy and Orson Scott Card's Ender's Game. This kind of science fiction has a certain epic scope to the story. They contain galaxies fighting each other for power, phenomenal depictions of aliens, a twisted concept of time and many more.

Other than the space opera's there are also those that base the stories on speculative fiction. They review current society and try to excogitate what the society will be like a hundred years from now by crystal ball gazing.

Given the growing popularity of these books every year sees a slew of new series and collections. If you are mesmerized by the concept of science fiction but have never tried reading one, then start with a small book. Skim through it before purchasing to determine whether it has a writing style that you like. The ones that are easy to read will prove to be more interesting since you are not likely to get too caught up with jargon that is incomprehensible.

If science fiction books interest you then fantasy may be another genre that you might want to try since both these genres have a similarity between them. If has been seen that if one genre invokes you, the other will too. One major difference is that fantasy books tend to be set in medieval times and often deal with magicians and sorcerers while science fiction books tend to be more about technology, gizmos, aliens and are set in a futuristic time zone.

Unashamed Science Fiction Fans Unite!

I love science fiction. I have since childhood... third grade, I believe. My oldest sister came home from visiting our dad in Florida with a copy of Robert Heinlein's "The Star Beast" and tried to get my other older sister to read it. She wouldn't. I would (then my other sister read it just to keep up). I was hooked. It didn't take long to find that some people consider loving scifi a little, or even a lot, strange. I've talked to people who just don't understand science fiction at all, or picture it to be like the stuff printed in the old pulps; you know, all blasters and bug eyed monsters, mad scientists and beautiful daughters. And then there are the people who flat out disapprove of it. How dare anyone speculate on such a level! My inlaws think my husband and I need to clean out our selection of scifi and just read the standard bestsellers, or better yet, nonfiction! Yawn! Just not my style. I see nothing wrong with enjoying being a scifi fan. If you're reading this, you probably don't either. It's fun seeing science fiction hit more and more of the mainstream. You see it on television. You see it in top movies. You see it on the bestseller lists. And yet to many there's still that stigma. Being a geek is more fashionable now, but it doesn't necessarily mean becoming popular. Loving science fiction to many is just plain weird. Thank goodness there are so many of us who love the weirdness. Dressing up for conventions, waiting in long lines to see the movie the first night... in costume, no less, is just a part of the fun. It's to be embraced. I love introducing people to science fiction. I've talked people into reading science fiction novels who were shocked that it included themes they love in whichever brand of fiction they already loved. To them, the idea that it could have a great storyline, romance, adventure, whatever, was truly astonishing. Sharing your favorite science fiction television shows, movies and novels with people who think they have no interest in it is fun. I urge all of you to try it. Some will appreciate the experience and you might end up with a new friend to drag to conventions, or at least talk about favorite stories with. Also make sure you share your favorites with your fellow fans. How else are they to hear about the great books, movies or television shows that somehow escaped their notice. How else are you going to drive the people who still don't understand loving science fiction utterly nuts?

The Camera and the Influence of Digital Technology

In the study of the camera, digital technology influence comes from a variety of different sources to give rise to modern digital photographic capabilities. Some of these technologies are then advanced in special niches to create new advances in science. One of the best examples of this exchange of digital technology is the CCD or Charge-coupled device. This is the digital technology breakthrough that made the digital camera possible.

When light strikes the CCD surface, it frees electrons to move around and those electrons accumulate in capacitors. Those electrons are "counted" at regular intervals by a circuit which dumps the electrons from each point on the CCD surface. When all of these measurements are combined, a picture can be instantly reproduced as a "virtual mosaic" of the individual point measurements. This is the picture we see. The more points of measurement found on the CCD, the higher the "resolution" of the resulting picture.

When building a highly specialized camera, digital technology such as this opens new doors which are not possible with film based technology.

In dentistry, an X-ray machine can be converted to a digital camera with a CCD which is sensitive to the photons that make up the X-ray spectrum. Instead of imprinting an image of X-ray on film, developing the film and finally reviewing the tiny film image, modern X-ray cameras can instantly display an X-ray image on a computer screen as the CCD processes the array of photon measurements. This not only saves time, but also produces no waste in the form of exposed film and development chemicals. So with this frequently used, specialized camera, digital technology creates improvements in a dentist's practice and protects the environment.

Another specialized camera that benefits from digital technology is the telescope. Traditional cameras, mounted to telescopes collect points of light and expose the film. This can provide more sensitivity than the human eye to faint points of light, but brighter points of light can also obscure fainter ones by "washing out" the image. With the application of digital technology the film camera is replaced by a digital camera using a CCD. The CCD can continue to receive and measure photons indefinitely. This means the process is a continuous measurement in contrast to the more simple exposure of a piece of film. Computers can then electronically filter out brighter sources of light making possible the detection of very faint points of light in the sky and even the study of celestial objects by the detection of the shadows they cast instead of the light they give off. By comparing the light collected over time, digital technology also allows this digital camera to detect distant objects by inferring their presence.

These are just two examples of how cameras are influenced by digital technology. New applications and even new science can result from such seemingly small advances in technologies that don't seem to be related at all. Think on this the next time you examine your own digital camera.
