The Cast Narrator Abhinav – student Vinay – student Chetan – student Pradeep – person in 2114 Ravi – person in 2114 Shiv – person in 3114 Setting : A time machine is kept at the centre-back.  Narrator:         Mankind has travelled a long distance from the time we evolved out of the apes.  Somewhere along the way, we became civilised.  We started living more like human beings with reason and imagination than like animals with endless hunger.  We leant to respect others, their languages, religions, cultures.  We learnt to cooperate rather than compete.  We replaced kings and dictators with elected leaders.  We opened up national borders in the name of globalisation.  The world has become a global village.  Everyone is linked to anyone in the world.  The smartphone and the internet, chat zones and the digital technology – together they had made our life very easy, comfortable and lovely.  But is it really a world better than the past?  Will the future be better

In response to Karan Thapar’s article which appeared in The Hindu a few days back, (which also inspired my last blog: From myths toward mathematics ), an ISRO scientist writes in today’s Hindu : “I am a retired scientist/engineer who worked in one of India’s premier scientific organisations, ISRO, for 38 years.  I believe in Ganesha, and that Shiva exists in Kailash, often riding on his bull.  Can anybody accuse me of having two faces?” I can and I do, dear scientist.  The myths to which Ganesha and Shiva belong and the science which you make use of for probing into the outer space far beyond Mount Kailash are not compatible.  One destroys the other.  Science replaces myths with facts, and myths have always killed scientists literally and metaphorically.  Don’t forget the scientists who were subjected to inquisition and incarceration during the medieval period.  Don’t ignore the crusade that continues even today against science in other names such as jihad. But I won’t ta

Courtesy: The Hindu 11 – 10 = ½ = 0.5 The equation on the blackboard baffled me as I walked into a classroom where I was given an exam duty.  Somebody had rubbed out something, I thought.  My mind started playing its usual game.  Come on, change it, said my mind. This is how I changed it:  11 – 10 = 1 I erased two figures mentally, the denominator 2 and the final decimal part of the equation.  Such a simplistic solution failed to satisfy me especially since I had a lot of free time in the exam room.  Seeing my solution, Sherlock Holmes would have said, “Elementary, Mr Matheikal.” My mind made the following equation: (11 - 10 ) ÷  2 = ½ = 0.5 That was neat, said my mind.  I had added a denominator 2 to the first part of the equation.     11 – 10 = 1 = 0.5 x 2 What I did was to transpose the denominator 2 to the RHS (right hand side) of the equation. One could go on.  How far you go with it depends on your capacity to work with numbers as well
