A brief history of Hans Lipperhey.

Hans Lipperhey was born in Wesel (western Germany) and settled in Middelburg, the capital of Zeeland, the southwesternmostprovince of the Netherlands, where he married in 1594 and became a citizen in 1602. His craft was that of spectacle-maker.Middelburg was a flourishing city, especially after the fall of Antwerp to the Spanish in 1585, which caused many of itsProtestant inhabitants to flee north to the Netherlands.

Minute of Lipperhey's patent application .

New glass-making techniques were introduced here by Italians in the 1590s, and perhaps some ideas about combining lenses wereabroad in this glass-making community. Although others have claimed the invention of the telescope and the device was impossible to keep secret, the earliest record of the existence of such adevice is a letter of the government of Zeeland to its delegation to the States General of the Netherlands, dated 25September 1608, which instructs them to be of help to the bearer, "who claims to have a certain device by means of whichall things at a very great distance can be seen as if they were nearby, by looking through glasses which he claims to be a newinvention."

Van Helden, The Invention of the Telescope, p. 36.
On 2 October the States General discussed Lipperhey's application for a patent on the instrument. Although the patentwas eventually denied because it was felt that the device could not be kept a secret, Lipperhey made several binoculartelescopes for the States General and was paid handsomely for his services.

Shortly after that, the States General were also petitioned by Jacob Metius of Alkmaar, a city in the north of the Netherlands,who also claimed to be the inventor. The claim of yet a third person, Sacharias Janssen, also a spectacle-maker in Middelburg,emerged several decades later. The surviving records are not sufficient to decide who was the actual (or as it was put in theseventeenth century, the first) inventor of the telescope. All we can say is that Lipperhey's patent application is theearliest record of an actually existing telescope.

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
what is the actual application of fullerenes nowadays?
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

Mostly, they use nano carbon for electronics and for materials to be strengthened.
is Bucky paper clear?
carbon nanotubes has various application in fuel cells membrane, current research on cancer drug,and in electronics MEMS and NEMS etc
so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Do you know which machine is used to that process?
