I have to agree with Robert, who appears to have constructed an amazing instrument!
Surely, there is room in this world for *two* types of sundials: (1) Those that stay true to the concept of time before mechanical clocks, when local apparent solar time was the "real" time, no matter what time was used anywhere else. (2) Those that include various corrections (like equation of time, local longitude versus time-zone meridian, and standard/summer time) and are intended to show exactly the same time that would be indicated by accurate civil clocks. -- Roger ----- Original Message ----- From: "Robert Bargalló" <bargallorob...@gmail.com> To: <sundial@uni-koeln.de> Sent: Sunday, September 27, 2009 11:57 AM Subject: Direct reading Dear Willy, My long experience to persons outside the sundials is as follows: A). Too complicated analemmatic figures or the necessary use of algebraic calculations to know the time that they consider the real one; for this reason, these people think the solar quadrant as an obsolete object. B). The same persons in front my sundial of direct reading increase the interest in gnomonics to consider these instruments as a “scientific precision apparatus”. Thus, direct reading encourages people towards our passion: the solar quadrants. -------------------------------------------------------------------------------- > --------------------------------------------------- > https://lists.uni-koeln.de/mailman/listinfo/sundial > > --------------------------------------------------- https://lists.uni-koeln.de/mailman/listinfo/sundial
