TECHNOLOGY.... TODAY ,TOMMORROW.....

        Nowadays can you imagine a mobile phone without a touch screen?The technology has so evolved such that the minimum requirement in today's mobile phone is a touch screen. Ohh....sorry recently touchscreen has started shifting its place to almost all the systems that are under human control. However, Texas A&M University's Interface Ecology Lab is working under a very promising technology- Zero Touch.

The Future Technology

       Zero Touch is not like other touch screens which are neither capacitive nor resistive (or any other type). Zero Touch screen is on the principle that a series of light will be projected across the screens by a number of Infrared (IR) sensors and Infrared (IR) LEDs. And the screen is touched when there is an interruption to these "invisible" light beams. Now these interruptions can be visualized to create a visual hull of any objects in the frame of these IR sensors.
        However, this concept is very much similar to capacitive touch screens where any interruption in the electrostatic field is considered as some kind of interaction with the screen. After all this is going to be much more interesting when it comes to real world.

Who knows in future whether the electronic systems touch you one day and wait for its processing....

Apart from our Sun, scientists have found more than 500 planets around the star, a majority of them spin in the same way as their star does. But for everything there will be at least one exception, that is a universal truth. Like that there are some extra solar planets that orbit around their star in a direction which is opposite to what is done by their star.These backward spinning giants are nick-named as "hot Jupiters" as much of them are gassy giants and not "rocky" as our Earth.
Actually scientists are very much weird about these "flipped orbits" as unlike Jupiter these "hot Jupiters" are much closer to the star and the scientists explain the reason for their astonishment. Orbiting in opposite direction and that too so much closer actually violates the basics of star-planet formation. According to astronomical theory big gas planets are formed far away from the star and the Earth like rock planets are born nearer to the star. But at the same time Astronomy itself are giving answers to this question: When the planetary systems contain more than one planet, apart from the star, each planet will have its own gravitational force that eventually will pull the gas giants closer to the star. This phenomenon the scientists named "Gravitational Perturbation".
