think that way or are they still coming into terms with the changes in the society. But for some,religion is more important than mankind and humanity. And the person who was a scapegoat to suchactivities of ruthlessness and violence was the innocent computer graphics teacher Rizwanuir Rehmanin Kolkata. His only crime was that he loved and got married to a girl that did not belong to hisreligion and status. He got married to Priyanka Todi, the daughter of industrialist Ashok Todi ofKolkata and the price that he had to pay was his own life, a month ago. His body might have beenburied but truth always finds a way to come out of the grave and starts haunting the culprits. With theCBI into the matter and the Prime accused being Ashok Todi himself, Rizwanuir’s family are surelyon the verge of getting justice. Justice was also done to Mukesh Ambani for his efficiency and abilityin taking the Reliance Brand to higher peaks as he became the richest man in the world surpassingBill Gates. He is the first Indian to achieve this landmark and I expect that he guides RelianceIndustries along with India to cover more distant milestones. The students in India are also set to takeon the acid test of CAT examinations to cross one of the biggest milestones in their life. Each year thecompetition grows tougher and the story is no different this time around. I won’t be surprised to seethe percentile rise this time. Finally I wish all the aspirants best of luck and may the deservingpersons get through.[For any feedback or information regarding this article, viewers can mail me atamitdash_nist@yahoo.co.in]Tech CheckSrastanka Kumar Behera & Ankan GhoshB. Tech., 7 th Sem.Password-Protected BulletsSafety catches do not always prevent firearm accidents and even newfangled biometric guns, whichcheck the identity of a user by their fingerprint, cannot stop thieves from using stolen ammunition inother weapons.The way to make firearms really safe, says Hebert Meyerle of Germany, is to password-protect theammunition itself.Meyerle is patenting a design for a modified cartridge that would be fired by a burst of high-frequencyradio energy. But the energy would only ignite the charge if a solid-state switch within the cartridgehad been activated. This would only happen if a password entered into the gun using a tiny keypadmatched one stored in the cartridge.When they are sold, cartridges could be programmed with a password that matches the purchaser’sgun. An owner could set the gun to request the password when it is reloaded, or to perform a biometriccheck before firing. The gun could also automatically lock itself after a pre-set period of time haspassed since the password was entered.The system would undoubtedly cost more than a conventional gun, but many firearm enthusiastswould surely pay a premium for such added security.Nanotubes Turn Paper into a Power SourceConventional capacitors cannot store much energy, but researchers have begun to experiment with“supercapacitors” created using carbon nanotubes as electrodes.
