How can We Use Water to run Cars?
Huge amounts of polluting gases are being released into the earth’s atmosphere by the large scale burning of fossil fuels or natural fuels found under the earth. These gases are the main culprits behind the phenomenon of global warming and other climatic changes. In order to find cleaner fuels, scientists around the world are trying to find a fuel or source of energy which produces little or no pollution on being burnt. Quite amazingly, a new technology points out that water can be used to generate electricity....

What is the Software for Life?
We all use computers. If you use Windows on your machine, like me, you will have a small button at the the bottom of your screen called ‘Start’. Every machine in the world which has the Windows software installed has to have that button. However, we can have different screen colours, different text sizes, wallpapers etc. Similarly our bodies are essentially the same, but we have different colours, sizes, shapes and structures. Our body also has a software which is responsible for these differences between one human being and another....
Where did Jazz Originate?
One has just to blow a note on a sax and your feet start tapping to the rhythm and your body starts swaying to the music. That’s Jazz for you. Ragtime, hip-hop, be bop, cool, blues – the very names make your finger snap and do a Texas two-step, no? Jazz has often been called the only art form to originate in the United States, though even this is not exactly true. Jazz, is a kind of music that was sung or played by the African slaves in the plantations of America....
What does a Train Whistle tell us about the Universe?
I remember my first visit to the railway station as a child of five. The excitement of the approaching train was an experience I have never quite forgotten. At first I heard a train whistle far away, low and distant. As the train got closer, the sound of the whistle not only increased, it became shriller, and difficult to bear. So much so that I covered my ears in alarm! Once the excitement had passed, I discovered a secret – even with my eyes closed and by just hearing the whistle, I could tell whether a train was approaching or moving away....
Where does the Pigeon Post Operate?
Among birds, pigeons have a natural and unerring instinct of returning to their nests or homes after long flights. In the early days besides domesticating animals like the horse, dog and cow, people also bred pigeons to carry messages back and forth. These pigeons are called homing pigeons. Racing pigeons have a life span of 15-20 years. A healthy bird can fly stretches upto 1,000 km. Normally the message is tied around the feet of the pigeon in a plastic capsule to protect the paper....
How did Christianity Come to India?
Would you doubt my word if I say that Doubting Thomas, one of the Apostles of Christ visited India and established Christianity? Don’t. For its true. Among Christ’s 12 apostles, Thomas Didaemus or Doubting Thomas, along with Peter and Paul were pre-eminent. Thomas Didaemus was called Doubting Thomas because he doubted Christ’s word that on the third day after his crucifixion, Christ would rise again. There are many schools of thought as to how Christianity spread in India....
Why are Zebras Striped?
As a child I was always full of questions. I remember asking my parents why zebras were striped or why did giraffes have such a long neck. Most of the time the answers were elusive and I used to be very irritated. I could never get the right answer to satisfy my curiosity. I now realize why my parents could not give me a concrete answer. You see I happened to be in the same dilemma when my three-year-old daughter asked me the same question!...
Who stole the Candle Wax?
On every Diwali, known as the festival of lights, our family has a big discussion on the kind of lighting we should have. And after talking about candles or electric bulbs we invariably choose the _diya_s or earthen lamps for their beautiful flames. But last year, we reached the kumhara or potter’s roadside shop a bit too late. The lamps had been sold out and the potter had a big smile on his face. So we decided to light candles....
What is an Earthquake?
One moment, the world seems just the way it was yesterday, the day before, last year, or even the day before the day before. All is well with the world. It’s a beautiful sunny day and you are sitting drinking your morning tea or coffee relaxed and enjoying the day. Suddenly there is a rattling of plates and glasses. Within seconds chairs and tables are rocking violently, the fans sway crazily and crockery is falling off the shelves....
