It is quite a common belief that Italian astronomer Galileo Galilei invented the telescope but this is not strictly true. The earliest workings towards the design of the refracting telescope were made by German-Dutch lensmaker Hans Lippershey (above) in 1608. During Lippershey's time, the name 'telescope' was not used until three years later and he referred to his design as a 'Dutch perspective glass', which he used for 'seeing things far away as if they were nearby. '.

Galileo, though, was the first person to use a telescope for astronomical purposes after hearing about Lippershey's work in 1609. He improved on Lippershey's design and using his new telescope in 1610, he discovered the four largest moons of Jupiter (Io, Ganymede, Callisto and Europa) and physical features on the Moon.

The first person to apply for a patent for a telescope was a Dutch eyeglass maker named Hans Lippershey (or Lipperhey). In 1608, His telescope had a concave eyepiece aligned with a convex objective lens. Copernican principle, named after Nicolaus Copernicus, is a working assumption that arises from a modified cosmological extension of Copernicus' Sun centered Heliocentric Universe.

The Copernican principle assumes that neither the Sun nor the Earth are in a central, specially favored position in the universe. More recently, the principle has been generalized to the relativistic concept that humans are not privileged observers of the Universe. In this sense, it is equivalent to the mediocrity principle, with important implications for the philosophy of science.

Galileo Galilei was an Italian polymath: astronomer, physicist, engineer, philosopher, and mathematician, he played a major role in the scientific revolution of the seventeenth century.

His contributions to observational astronomy include the telescopic confirmation of the phases of Venus, the discovery of the four largest satellites of Jupiter (named the Galilean moons in his honor), and the observation and analysis of sunspots. Galileo also worked in applied science and technology, inventing an improved military compass and other instruments.

In 1581, when he was studying medicine, he noticed a swinging chandelier, which air currents shifted about to swing in larger and smaller arcs. To him it seemed, by comparison with his heartbeat, that the chandelier took the same amount of time to swing back and forth, no matter how far it was swinging. When he returned home, he set up two pendulums of equal length and swung one with a large sweep and the other with a small sweep and found that they kept time together.

Galileo, was an Italian physicist, mathematician, astronomer and philosopher who played a major role in the Scientific Revolution. His achievements include improvements to the telescope and consequent astronomical observations, and support for Copernicanism. Galileo has been called the "father of modern observational astronomy",the "father of modern physics",the "father of science" and "the Father of Modern Science". Stephen Hawking says, "Galileo, perhaps more than any other single person, was responsible for the birth of modern science."

Discovery - The process of finding information, a place or an object, especially for the first time, or the thing which is found the discovery of electricity.

Leonardo made many scientific discoveries. A journey/voyage of discovery.

The discovery of a body in the undergrowth started a murder enquiry.

Inventions - Something which has never been made before, or the process of creating something which has never been made before.

The world changed rapidly after the invention of the telephone. A most amazing invention.

The actual inventor is confirmed on the basis of the stories that are really funny and interesting. Hans Lippershey was a spectacle maker and it was in his shop that the first kind of telescopes was discovered.

They were accidently found out by the children who visited his shop for fun. Thus Lippershey can be considered as the inventor of telescopes. There were several people coming up claiming the same invention that they made and wanted the credit of the invention of telescope along with Lippershey.

Galileo Galilei, was an Italian physicist, mathematician, astronomer, and philosopher who played a major role in the Scientific Revolution.

Born: February 15, 1564, Pisa.

Died: January 8, 1642, Arcetri.

Education: University of Pisa.

Discovered: Ganymede, Europa, Callisto, Io.

Children: Maria Celeste, Vincenzo Gamba.

The fundamental theoretic basis of modern astronomy, demonstrated by Nicolas COPERNICUS showed that the earth and other planets orbit around the sun.

The copernicus principle has some practical applications-some scientists use it when forming statistics and some even believe that it could be used to determine how long the human species would last on the earth!

Galileo was not an inventer of telescope also use the telescope for the observation and experiment. Because the telescope is a dutch optical instrument is pre-exist. Before the experiment of Galileo. He aslo uses the different technique in pendulum and find the result and also provide the limitation and property of pendulum.

Invention: Bringing or creating new things in the world which did not exist before.

Discovery: Finding out existing things or phenomena which were unknown to humans before and are still natural.
