Teleportation
Probably you remember the amazing star trek series where some people often traveled to any location of the universe by disappearing themselves at a special room of the space ship. This room comprises a machine named transporter that is required to conduct the teleportation. Basically, it is a platform where the crews stood on. The transporter machine then locked onto each atom of each person on the platform, and used a transporter carrier wave to transmit those molecules to wherever the crew wanted to go. This is a story of teleportation.

Now the concept of teleportation comes into reality. Physicist Charles Bennett and a team of researchers at IBM confirmed that quantum teleportation was possible, but only if the original object being teleported was destroyed. In 1998, physicists at the California Institute of Technology (Caltech), along with two European groups materialized the IBM ideas by successfully teleporting a photon, a particle of energy that carries light. The Caltech group was able to read the atomic structure of a photon, send this information across 1 meter (3.28 feet) of coaxial cable and create a replica of the photon. As predicted, the original photon no longer existed once the replica was made. Recently, teleportation success was achieved at the Australian National University (ANU), when researchers successfully teleported a laser beam.

Human teleportation is a complicated issue because highest precision is mandatory in this regard. Without exact order and arrangement of atoms that make up the human body causes fatal consequences. On the other hand, tele-travelers have to die, in a sense. Their original mind and body would no longer exist. Instead, their atomic structure would be recreated in another location, and digitization would recreate the traveler's memories, emotions, hopes, and dreams. Therefore, the travelers would still exist, but they would do so in a new body, of the same atomic structure as the original body, programmed with the same information.

Tip 1: Hyperlinks in Office applications
In MS Word or other office applications, the email ID or URL becomes blue underlined as soon as you complete it. Sometimes it seems to be troublesome and requires a solution. In Office XP follow these steps…
Open MS Word or any Office application
Click Tools>Auto Correct Options>AutoFormat As You Type
Then uncheck 'Internet and network paths with hyperlinks'
Click Ok

Tip 2: Block pop-ups
Pop-up window is a kind of annoyance and sometimes it breaches security. So you must aware about the unwanted pop-ups. Although you get several software to block pop-ups but your native-browser Internet Explorer (IE) also offers this facility. Follow these steps in Windows XP…
Open IE
Click Tools>Pop-up Blocker>Turn off Pop-up Blocker
This setting sometimes generates problem. If you want to allow pop-ups from any specific Web sites again follow these steps…
Open IE
Copy the site address
Click Tools>Pop-up Blocker>Pop-up Blocker Settings
Paste the address into the 'Address of Web site to allow' field
Click Add
Then click Close

Tip 3: Relocate the address bar
You insert the URL into the address bar to access the desire Webpage. If you want it in the taskbar follow these steps in Windows XP…
Right-click an empty area of the taskbar
Choose Toolbars>Address
If the taskbar is locked, you first uncheck 'Lock the Taskbar'
Then you drag the taskbar up and down to get proper view of the address bar
