Nicholaus copernicus







                                NICHOLAUS COPERNICUS

Nicholaus Copernicus was born on February 19,1473  in torun, a town in Poland. His father was a wholesale copper dealer and probably the family got its name from this. Nicholaus is the youngest. His parents died by the time he reached ten.  He was brought up  by his uncle Lucas  Waczenrode who sent him to university of Krakow. When Nicolaus was twenty two he became canon at the
cathedral of Frauenberg.
The universities had become exciting places with Renaissance especially in Italy which is origin of Renaissance. Copernicus moved to university of Bologna in 1496 when he was 23. Later from Bologna he moved on to Padua and Ferrara.   At bologna he joined as a pupil and became an assistant for Professor Dominico Maria Da  Novarra. Under him he set down his first record
His own studies revealed many wrong concepts in the Ptolemy’s earth centred universe. He   began to consider another idea of universe in which sun was at the centre. He was not the first person to recognise it. Many Greek philosophers like Pythagoras kept his theories close to it. 
In 1503 he returned Fauenberg to take up his duties at the cathedral. He remained with his uncle from 1506  to 1512 when he was ill.  He passed away in 1512. So he returned to cathedral and set up his laboratory on roof. He used o climb up the roof for his observations.

In 1540 he published his first book called De Revolutionibus Oribum Celestium. He received an encouraging response from all including church authorities. So he published De Revolutionibus just before his death in 1543. There is a legend that he died on the same day his book emerged from the press.......!!!!!!!!!!!!!

A New Technological approach

Actually in present times advanced technology has been creating disasters.  So Pessimists are coming up with the idea that scientific research should not be encouraged. It is not correct to say in that manner. Without science we would not have been reached that stage. There is still need to scientific research as people are becoming so lazy to do any work. We need servants to do our work.  But now a day’s people attitude is becoming narrow. They just wanted themselves to develop. The “most generous people” of this generation will be thinking up to their country. So as long as the people’s attitude doesn’t change it is not appreciable to go against pessimists. As long as the governing bodies can’t control the selfish narrow minded politicians and technocrats it is not appreciable to encourage the upcoming scientific research. Let us motivate our generations and keep alive our scientific progress.
