Dear Friends,
This is looking strange to see a science related article in music related
blog, but true; this is because, we are living by taking help of science.
Music is no far from science; as all we know how nearest relationship
is there to music with science.
Pls give a tribute to all those scientists, who given their contribution to
the world.

Galileo's telescope reaches 400th anniversary
It is 400 years since Galileo Galilei demonstrated his telescope,
which would lead him to make new astronomical observations

While many people have been loudly celebrating this year's double commemoration of 200 years since Charles Darwin's birth and 150 years since
the publication of On the Origin of Species, another scientific anniversary has crept up relatively quietly, marking an event which arguably changed human thought and the way we see ourselves even more irrevocably.
Exactly 400 years ago today, on 25 August 1609, the Italian astronomer and philosopher Galilei Galileo showed Venetian merchants his new creation, a telescope – the instrument that was to bring him both scientific immortality and, more immediately, a whole lot of trouble.
A refinement of models first devised in the
The moon was not, as long believed, completely smooth. Another planet, Jupiter, also had moons. Meanwhile Venus showed a range of moon-like phases, something which could not happen if both it and the sun orbited the earth.
This latter phenomenon had been predicted by Nicolaus Copernicuswhen, nearly a century before, he had proposed the notion of a planetary system with the sun at the centre, not the earth.
Galileo's discoveries were, perhaps predictably, not best welcomed by the Catholic church, and he spent the final decade of his life under house arrest.
It was certainly a revelation which upset the orthodoxies – and the churches – at least as much as Darwin's, and perhaps merits a bit more of fuss, although museum-goers in Philadelphia and Stockholm can view one of Galileo's very early telescopes, on loan this year from Florence. A good deal more people are likely to be alerted thanks to Google's day-long adaptation of their main page logo to a Google Doodle in honour of the event.
On August 25th, 1609, an Italian astronomer showed off his unique creation to a group of Venitian merchants. The object was able to magnify the night sky, revealing celestial objects nobody could ever find or study before.
By now you probably know that I’m referring to the telescope and that Italian astronomer was none other than Galileo Galilei.
