What Are Quantum Computers

January 23rd 2010 20:19

Recently there has been much talk about the limitations of present day computer technology. Although new modern computers are emerging every time with some thing new and with much more power and speed. But all this is still based on the convetional silicon based technology. Which scientists think will one days saturate.

This just something that is their in every technology and scientists have to find a new alternative to meet the increasing needs of mankind. This problem of massive computational power had already been looked upon much earlier when scientist found the need of such power which could replace the large super computers already in use.

It is true that even the present day super computers cannot deliver enough power to calculate certain scientific problems. All this lead to the research and development of Quantum computers. Although this technology is still under research but scientists hope for a better future.

But what Quantum computers really are? To understand Quantum computer you should know what is Quantum mechanics and to do that you must know your physics really well. The entire mechanism of Quantum computer is based on certain phenomenons with in the atom.

And this is studied under Quantum mechanics. These things happening with in the atom actually can be used to store data in quantum bits and that to in an atomics scale. Presently we employ a small circuit with in an IC to do this. So one can imagine that doing the same thing on an atomic scale will drastically reduce the size of our computers.

Also taking the computational mechanism to the most basic level of matter will greatly increase the speed of computer allowing us to revelutionize everything. Scientists have developed some basic quantum computers but there are still many years before anything practical could be developed. However we can still hope to see anything like that in our lives.

WiTricity

November 27th 2009 14:24

WiTricity is the latest innovation in modern technological enhancements. This technology is thought to revolutionize the way we use our electrical equipments. The technology was discovered some 100 years ago but at that time people were not aware of its practical feasibility.

But now in the present age we are living in an electronic world and there are a dozen electronic gadgets all around us. All of these gadgets run on electricity most of them require wires and some require portable batteries which still require chargers. So without wires in our lives electronic gadget would be useless.

But WiTricity Corporation is confident that experiments in this present technology can change the way we run our electronic gadgets. If this technology is successful on commercial scale we might not even need any wires to run our gadgets.

The WiTricity is based on the electromagnetic coupling of two coils that are placed near from each other. The resultant electromagnetic coupling produces resonant field that can be matched with a coil in a device nearby inducing a current in it.

The process is similar to what occurs in transformers but in transformers the coils are mounted on each other. This phenomenon was demonstrated at the TED Global Conference held at Oxford in July 2009. In this demonstration 3 different mobiles where shown to work using WiTricity.

Jhonson & Jhonson Baby Shampoo Contains Unsafe Chemicals

March 20th 2009 17:52

Everybody knows the famous brand Jhonson & Jhonson and many of us have used their products in our childhood or are buying their baby products for our babies. I personally liked their baby shampoo and washed my hairs with it even when I became a teenager. But recently when I saw this strange news about their shampoo I was feeling really bad as I couldn't stop thinking that all these years I was putting some sort of poison on my hairs.
