Strategies for Cracking UPSC-IES, GATE Exams

-
Ever since I have cracked (IES: AIR 14, GATE: Rank 64) these two sacred exams for Engineers, I feel contented as far as clearing exams are concerned. But I have learnt a lot from the competition inherent in these exams. Lacs of candidates, millions of coaching institutes and zillions of aspiring souls in the form of parents of these candidates. These parents spend lacs on the coaching of their budding engineering sons/daughters just to satisfy themselves that they have done their duty.  According to me, if a candidate has completed his engineering or if candidate is a final year student of Engineering - Coaching is not required atleast for cracking GATE or IES !! GATE: Its an aptitude exam for checking that graduates have acquired requisite skills expected from an qualified Engineer.  IES: Its a comprehensive exam which checks the ability of graduates to take up Group A Services of Govt of India. It is more than aptitude exam and to me it appears to me as attitud...

NanoComposites in Tennis Balls

-
Nano composites consists of nano sized particles embedded in some type of matrix -are group of promising new materials being infused in some of our modern technologies.  One type of nano composites is currently being used in high performance tennis balls. These balls retain their original pressure and bounce twice as long as conventional ones. Air permeation through walls is inhibited by a factor of two due to presence of a flexible and very thin (10 to 50 microns) nanocomposite barrier coating that covers the inner core. This nanocomposite coating consists of matrix of butyl rubber, within which is embedded thin platelets of vermiculite, a natural clay mineral. The vermiculite platelets exists as single molecule thin sheets- on the order of nano meter thick-that have a very high aspect ratio.  Furthermore vermiculite platelets are exfoliated that is they remain separated from each other. Also within the butyl rubber, the vermiculite platelets are aligned such th...

A day before UPSC-Engineering Services Exam

-
O ne of the toughest day- if I can recall. IES exam is spread on three days -Friday, Saturday & Sunday to test your abilities through 5 papers- GAT, Paper-I (Obj), Paper-II (Obj), Conventional Paper-I, Conventional Paper-II. Torture continues till Sunday ! When I concluded my preparations, I had no idea whether I would be able to make it to the elite list of IES qualifiers. But to some extent I was satisfied with my performance, this I thought made me comfortable. Never ever think of end results- just have faith in you and your capabilities which you have build through the preparations in the last 6-7 months or so.  During the preparations I had prepared two small notebooks in which I used to write important concepts and formula to revise them frequently. But before exam day when you have to solve Conventional Papers that too in Mechanical Engineering that too for Engineering Services- everything seems inadequate and so was my note book. I read it, re-read it and kept i...
