imatfaal Posted November 15, 2016 Share Posted November 15, 2016 What's the roman numeral for zero?? I think this is the nub of the issue - not so much the fact of Roman numeral for zero but the use of zero per se. We had time telling devices and (to an extent clocks) in Europe for centuries before we really used zero in any meaningful sense 2 Link to comment Share on other sites More sharing options...
michel123456 Posted November 15, 2016 Share Posted November 15, 2016 Why is this not the norm ? Zeroclock.png It has been done, but in the decimal system. And not always. Link to comment Share on other sites More sharing options...
Sriman Dutta Posted December 11, 2016 Share Posted December 11, 2016 If that's the case, then let me ask: Why 1 minute=60 seconds and not 100 seconds ? Link to comment Share on other sites More sharing options...
rangerx Posted December 11, 2016 Share Posted December 11, 2016 Because it is not called 'zero o'clock', it is called 'twelve o'clock'. 0000 is accepted though. Link to comment Share on other sites More sharing options...

rangerx Posted December 11, 2016 Share Posted December 11, 2016 (edited) If that's the case, then let me ask: Why 1 minute=60 seconds and not 100 seconds ? Minutes and seconds are increments of degrees latitude or longitude for measurements in navigation. 1 degree = 1 hour 1 minute = 1 nautical mile Edited December 11, 2016 by rangerx Link to comment Share on other sites More sharing options...
John Cuthber Posted December 11, 2016 Share Posted December 11, 2016 If that's the case, then let me ask: Why 1 minute=60 seconds and not 100 seconds ? Because 60 has more factors than 100 so calculating fractions of an hour is easier. 1 Link to comment Share on other sites More sharing options...
DrKrettin Posted December 11, 2016 Share Posted December 11, 2016 (edited) If that's the case, then let me ask: Why 1 minute=60 seconds and not 100 seconds ? You should blame the Babylonians, who had a sexagesimal numbering system. They divided the full circle into 360 degrees, presumably so that the sun moves about 1 degree every day throughout the year. Then the degree is divided into 60 minutes (of arc) and then 60 seconds (of arc). This idea is then copied with the face of the clock.
