Aurora 2005 EDITORIAL Aurora is GIKI's first and only official science magazine. First published by GIKI Science Society in 1999, it has been revived this year, to cater to the growing demand for such a publication. Aurora's basic aim is to provide a platform for GIKI students to voice their theories and research in various scientific fields. Also, Aurora aims to serve as GIKI's voice in the scientific community, giving an insight as to the scientific activity going on inside GIKI. This issue of Aurora includes Technical articles, Interviews, and a fun section, as well as Final Year Project abstracts and Research papers by prominent people of the field, including many of our own faculty members. It is a great opportunity for GIKI students to express their thoughts and ideas, and take their first steps into the world of scientific research and publication.

Science society has always played a very pivotal role to enrich this culture. AROURA is the official scientific magazine published by GIKI Science Society. It was last published in SPRING 1999 by batch 6. I must congratulate Science Society for reviving this tradition with such a great quality. All the articles and papers from the Faculty and Students of GIK Institute describe the newly emerging technologies. The idea of Science Timeline is also excellently implemented. In short, it is a great effort put up by GIKI Science Society and I once again congratulate them for their hectic effort. Dr. Ibrahim qazi Advisor, Giki Science Society Being the Advisor of GIKI Science Society, I will like to take the honor to congratulate GIKI Science Society on Publishing AROURA. Over the years, the Science Society has matured significantly. From humble beginnings, it has grown to become one of the most prestigious societies in GIKI, with an enviable reputation all over the country. AROURA is the official scientific magazine of the Institute. It was last published in SPRING 1999 by batch 6. It is a quality publication and one of major publication of its kind in the country. I once again like to appreciate the efforts of Science Society members and especially the editorial board ofAROURAfor bringing out this magazine.

For the cosmos to look concerns connect directly to cosmic ones. We can trace broadly the same everywhere, some kind of our lineage back through the generations, back through communication had to pass among distant regions of our animal ancestors, to early forms of life and protolife, to space, coordinating their properties. But the idea of such the elements synthesized in the primordial universe, to communication contradicts the old cosmological the amorphous energy deposited in space before that. paradigm. Does our family tree extend forever backward? Or do its roots terminate? Is the cosmos as impermanent as we To be specific, consider what has happened over are? the 13.7 billion years since the release of the cosmic microwave background radiation. The distance between The ancient Greeks debated the origin of time galaxies has grown by a factor of about 1,000 (because of fiercely. Aristotle, taking the no-beginning side, invoked the expansion), while the radius of the observable the principle that out of nothing, nothing comes. If the universe has grown by the much larger factor of about universe could never have gone from nothingness to 100,000 (because light outpaces the expansion). We see somethingness, it must always have existed. For this and parts of the universe today that we could not have seen other reasons, time must stretch eternally into the past 13.7 billion years ago. Indeed, this is the first time in and future. Christian theologians tended to take the cosmic history that light from the most distant galaxies opposite point of view. Augustine contended that God has reached the Milky Way. exists outside of space and time, able to bring these constructs into existence as surely as he could forge Nevertheless, the properties of the Milky Way are other aspects of our world. When asked, "What was God basically the same as those of distant galaxies. It is as doing before he created the world?"Augustine answered, though you showed up at a party only to find you were "Time itself being part of God's creation, there was simply wearing exactly the same clothes as a dozen of your no before!" closest friends.
