Virtually reality games based on the realism

The present graphics and games arena are highly developed when we compare with pixelated graphics of the computer before two decades. But now it possible to bring the real places in to the virtually realistic fields by virtually capturing the real surface with latest technology. With the latest multi-core processors and smart software, the scientists and engineers are trying to stimulate the real world in extreme detail to create virtual world actually governed by real physics. Therefore matrix like realities can be created that are indistinguishable from reality. The basic technique is to pass the bunch of rays in the scene and determining the color of the pixel considering the type of surface it hits. Hence the way it reflects or refracts off paves the way for the object as it is in the real world. It is possible to generate virtual world containing 2 to 3 million rays on every screen when user move through in real time with the animation rate of 10 frames per second.

Chances of secret water table in mars

The Mars which is known to be the Red Planet of the universe may have the water source in its secret water table. According to the satellite data this planet may have water in its underground, but when we consider the today’s fact the small amount of water detected on the planet will not be from polar icecaps as the geological features suggest liquid water flowed in its surface could be hiding beneath the rocky crust. There are various satellites researching this red planet for water, for example European Space Agency's Mars Express satellite has used ground-penetrating radar in some areas to look for a water table but no evidence has been found. Rather it may have the water surface below 9 km not within the reach of satellite instruments. When we consider the argument of the planetary scientist Bill Farrell and their team mates from NASA, the satellite radar signal should reflect back from shiny surfaces of water.

A new way to clean up the fallouts of Chernobyl nuclear disaster

We all know that it is almost impossible to clean the radioactive substance like strontium and cesium when there is a nuclear disaster like Chernobyl nuclear disaster; hence there is no growth of the food crops. But scientists have found a new way to suck up these radioactive substances by growing biofuels. It would take decades to clean up this mess by growing biofuels rather than wasting hundreds of years, thus make the soil fit to grow food again. The biofuels like radioactive sugar beet and other related crops can be grown in the contaminated lands. Nearly 40,000 square kilometer area of south-east Belarus is fully contaminated by these isotopes during the Chernobyl nuclear power station disaster in 1986. No radioactive material will get into the biofuels because ethanol is the only component distilled out. But in distillation heavy volatile substance like radioactive isotopes will be rise up in the stem tubes and it can be burned in power station to produce concentrated ‘radioactive ash’ for further disposal.

‘Superatoms’ in making faster computer processors and denser memory storage

The ‘superatoms’ are the cluster of atoms that share electron and mimic like the other element. It has been since 29 years, the discovery of these atoms by Walter Knight and colleagues at the University of California, Berkeley when they found the group of sodium atoms can share electrons among themselves. Now it has got the new breakthrough when they have been devised with the magnetic properties and it is very helpful in building novel nano-scale blocks with controlled magnetic properties to build faster computer processors and denser memory storage. The electrons from each atom collectively form the ‘supershell’ that coats like the cluster. It has been found that the superatoms of aluminum easily coats with other elements like noble gases helium or argon to form a cluster. This combination can help in create more efficient fuels because aluminum would release lots of energy when burned, thus it react with other elements too quickly to form solid fuel additive.

Your personal computer will not be ordinary anymore

Due to the development of multi-core CPUs and arrival of massively parallel cores in the graphical processing units, within some years the computer users will find a vast improvement in their processing speeds as well as in gaming platforms. In simple words, if we want to say the personal computer will transform to personal supercomputer. Now itself companies like Nvidia and ATI are offering multiple programming cores for their high end graphical system. They are programmed to do parallel processing tasks in almost every functions of the system, thus we can see the improved display features like video, especially in gaming. But they need some space and high power requirements at a hefty price therefore it is almost infeasible in many laptop designs. The most important thing is that these multi-core and programmable components must be virtually available to market at cheap rates then only is possible to fix into our systems.
