In a room laden with glass jars, tubes and chemicals, air rich with the intoxicating aroma of several chemical substances, a few men relentlessly toiling away in excitement in an effort to obtain something that would gift humans with the power to generate riches: a formula that can convert copper to gold. This is a typical scene from the stories set in medieval times depicting the life of an alchemist.

After a mugger kills Emma, his fiancee, Dr. Alexander Hartdegen, a young inventor who teaches at Columbia University in New York City, devotes himself to building a time machine that will allow him to travel back in time and save her. When he completes the machine four years later, he travels back in time and prevents her murder, only to see her killed by a horse and buggy. This is not a real story, but the plot of a movie called the “Time Machine” made in 1960. Of course, the original idea of time travel came from H G Wells’ famous book, ‘The Time Machine’, published way back in 1895.
Physicists for the last few decades have been on a hot pursuit of detecting one of the weakest signals ever, tuning their giant instruments to sense the presence of waves emanating millions of light years away during certain astronomical events. These waves are so feeble that even the sound of a passing wind on a nearly windless day is a thunderous roar compared to it.
The beautiful colours of a rainbow may attract us but seldom do we get interested in studying their origin. One may have seen similar colours on a CD disk. Asking a simple question as to whether these colours are similar could open up the secrets of nature.
When a Nobel Prize is announced media attention is drawn to the scientist receiving the Nobel Prize.

Many of us perhaps are not aware of the precise nature of the work of a scientist.
