Description:
Curator Thierry Lalande talks about decimal time (10 hours per day, 100 minutes per hour, 100 seconds per minute) put into effect in the French Republic in 1793. He points out that as we now measure time in shorter durations, our measurement system changes bases: specifically from base 24 (vegisimal) for hours in a day, to base 60 (sexagesimal) for minutes and seconds, then to base 10 (decimal) to subdivide the second.nnBackground: nnThe collection of scientific instruments at the Musée des Art
