  • Light Emitting Diode: Where Did This Technology Come From?  By :
    Light-emitting diodes (LEDs) were an accidental discovery at first. At the beginning of the 20th century, it was discovered that when electricity was applied to the semiconductor Silicon Carbide (SiC) it produced a light. This light was too dim to be of any use so the research was never distributed. This could have been the end for the LED, but it wasn’t content to die out.

    Nearly 20 years later Russian and German scientists revisited the idea of light produced this way. T...
  • Internet Fax And A Paperless World  By :
    We are slowly moving towards a paperless world. The papers that create clutter on our desks and in the filing cabinets are now being stored on CDs and DVDs. Our computers hold all the information that we require, and we do not need to look anywhere else. The email is perfect for sending our important letters and messages. These can instantly reach the concerned person's mailbox in less time than it takes to print a letter, fold it, and put it in an envelope. It is both conven...
  • Sensors Providing Superhuman Powers  By :
    Introduction

    In the movie, Superman, Superman spun the earth around to reverse time so Louis Lane could escape a driving tragedy. Nowadays we do not need Superman to avoid catastrophe… We can sense the conditions of roads miles before we get there.

    Spiderman uses his “Spidey-sense” to alert him of transgressions. We have our own sixth sense… We can learn of criminal actions without anyone being there to witness the event.

    We are acquiring more superpowers with each p...
  • What is the Future of Laser and Fiber Optics?  By : Rodger Bailey, MS
    We are living in an age when technology is the driving force that is moving us forward as a civilization. It seems that with each passing week new pieces of information give way to new pieces of technology which unravel and give way to more and more advances that push us into an age that may, to some critics, become so addicted to technology that we might be beyond help. Laser and fiber optics, computerized technology, and everything between are at the focal point of this technological evolution.
  • Cell Phone As Style Icon For Communication  By : Roberto Sedycias -
    Cell Phones, also known as Mobile Phones, have become a way of life. It is no exaggeration to state that in the modern times, it is almost impossible to lead a normal life without the help of cell phones.

  • How Metal Detectors Work  By : Phil Morris

    What is a metal detector?
    An electronic instrument that can find any instance of metal from the ground, a human body or a parcel is called me...
  • Geothermal Heat Pumps Far Superior  By : Chris Impeterelli

  • The Internet Phone Is All A Buzz Among Technology Buffs  By : Michele Oberton
    Years ago, a telephone was dialed manually and it featured a handset that we used to talk to our friends and family. While that telephone still exists today, the internet phone is changing the way people talk - literally.

Thus, “Biotechnology” basically means using ...
  • You Had Me At EVDO  By : Russell Snapper
    I have been having too much fun, so now is the time to get a little technical. The ironic thing is that today’s more technical comments are about technology that is meant to allow people to have a lot of fun on their mobile phones and waste tons of productive time just watching movies and TV from their phone. We have come full circle. Cell phones originally were developed to allow people to be more productive and now they will allow people to screw around anytime, anywhere. T...

  • Apple iPod Special U2 Edition  By : Danny Wirken -
    New iPod models have sprung up as quickly as mushrooms after the rain and each time they just seem to get better and better. I have to say though that this U2 special edition iPod just captured my heart the moment I saw it. Being very much a U2 fan, the fact that the back panel has the band members’ signatures engraved on it is enough reason in itself for it to be the best. The U2 iPod is easily recognizable from all the other models due to its style. While the others are usu...

  • Through The Looking Glass Of Web 2.0  By : Stephan Miller
    Until I tried it, the whole 2.0 thing seemed like a joke to me. But the switch between the Google, Yahoo, MSN search engine Web 1.0 war and the environment of Web 2.0 is drastic.

    For those of you who remember using a card catalog at the public library, the change is similar to the one you experienced using a computer to find a book for the first time. No endless cabinets of cards to hunt through. No misplaced cards that meant you wouldn't find the book you were looking fo...
  • A Review Of Digital Camcorders  By : Scott Michaels
    Digital camcorders that record directly to DVD discs are called DVD camcorders. Rather than recording to mini DV tapes, these models burn video to 8-centimeter DVD-RAM, DVD-R or DVD-RW discs. DVD-R and DVD-RW media can be read in most home DVD players, but DVD-RAMs are readable only in a few home players.

    Reviewers say there are some drawbacks to recording straight to DVDs. Because of frustrating incompatibilities between the various DVD formats and DVD editing software, r...

  • Antennas Of The New Age  By : Robert Thatcher
    Antennas have been around for a long time. Before the birth of cable television, homes would need it to just to get a signal. The person would need to put this on the roof and adjust it from time to time to get better reception. Satellite television has also changed this making these crude yet useful devices obsolete.

    The computer age has followed suit. There was a time that an individual had to dial up just to get an internet connection. With the development of wireless r...
  • Choosing Fiber Optic Patch Panels  By : James Croydon
    When surmounting trouble rises, an optic fiber technician must choose the most suitable patch panel for a particular situation. That technician must recognize that when it comes to easy installation, proper termination and long term maintenance, not all patch panels are created equally. Optic fiber is robust and therefore deserves some special treatment. For example: if a horizontal copper cable is damaged, one user will be affected. If a backbone fiber goes down, it can take...

  • Big Bang Booming - Back To The Future  By : Michael Strauss
    Theoretical cosmologists spend much of their time perfecting what is now known as the 'Big Bang' theory. This concept originates from ideas percolating in the minds of scientists, theologians and astronomers down through the ages. However, much of what they consider as proof for the 'Big Bang' is dependent upon uncontrolled experimentation that is molded to meet their expectations.

    Then God said, "Let there be light," and there was light. This ancient description of the cr...
  • What Are Telescopes?  By : Jason Adams -
    Telescopes act as windows to the universe. It is with the help of telescopes that we can study the solar system and view the conjunctions of stars. Not just that, the various planets, galaxies, satellites and asteroids that we get to see only in the books and magazines are made more familiar to us via the telescopes. They act as barrier- breaking instruments between the human beings and the outer space. The universe is no more a mystery to us that exists beyond our reach and ...

  • "We Don't Know What We are Talking About" - Nobel Laureate David Gross  By : MStrauss
    Science has reached an enormous impasse. From biology to physics, astronomy to genetics, the scientific community is reaching the limits of understanding which often presage a complete rethinking of long-accepted theories. So characteristic of this new apex of modern arrogance is the inability to comprehend the obvious in physics: That we don't know what we are talking about.

  • Why Using Noise Reduction Headphones With An Mp3 Player Is Better Than Earbuds  By : Shell Harris
    MP3 players and portable CD players usually come with the standard “earbud” headphones. Earbuds fit into the ear like a hearing aid and are lightweight and portable. Their advantages, however, stop there.
