galileo's proportional compass

Galileo combined the uses of both types of instruments, designing a proportional compass or sector that had many useful scales engraved on its legs and could be used for a variety of purposes, including gunnery (see fig. These lines have divisions on which appeared these symbols (Italian abbreviations): "or" (for oro, gold), "pi" (for piombo, lead), "ar" (for argento, silver), "ra" (for rame, copper), "fe" (for ferro, iron), "st" (for stagno, tin), "mar" (for marmo, marble), and "pie" (for pietra, stone). 1 34 Related Question Answers Found Who is the most famous astronomer?

Galileo’s escapement: A design for a clock escapement, invented around 1637. Generally, proportional compasses have, on their hands, various proportional scales, needed to define the ratio between Valentina Zaffino 3 lines, geometric figures and solids. 1-3 of 3 results | Next. The phenomenon of the sector is a dramatic paradox. The sector was invented, essentially simultaneously and independently, by a number of different people prior to the start of the 17th century. ( Proportional compasses Compasses whose legs carry proportional scales that serve to define proportions between lines, geometrical figures, solid bodies, and so on. Der Proportionalzirchel.
