Mii de bombe si de pipe!Cristian ,ia citeste tu textul de mai jos.Alt exemplu,drag mie: Bernard Schmidt a fost un optician autodidact foarte competent,pentru care teoria era la fel de importanta precum una dintre surubelnite,dar ursuz,destul de antipatic si cu prieteni putini.(Tipii perseverenti din acest brand de obicei au bani si amante multe).Ce noroc pe el,altminteri cineva-i demonstra ca optica  ce voia el sa  slefuiasca este imposibil de realizat.Respecta teoria dar  ''grind more ,worry less''.Mircea






CLACEY
   John Clacey was born in Massachusetts in 1857.  As a young man, Clacey 
ordered books and glass blanks for a six inch doublet, and in teaching himself 
lens grinding, by repeated failures reduced the blanks to a thinness that 
caused them to flex while being worked.  He was forced to order another pair of 
blanks and with these made a successful telescope and began developing his own 
techniques of local correction followed by testing with an artificial star, for 
] He made instruments designed by S. C. 
Chandler: the almucantar (used to detect the variation of latitude) and the 
chronodeik (used to determine true local time).  Clacey set up shop in 
Cambridgeport, and made many refractors of three, four, and five inches 
aperture, and over time made them of shorter focus, such as four inch f10 
models, and one five inch f4.2.  These were sold to amateurs and to the 
U.S.N.O., the Coast & Geodetic Survey, the Blue Hills Meteorological Obs., 
Brook's Smith Obs., the Japanese Navy, and others
