Solstice Sundial
Posted in Astronomy at 12:00 on 2 July 2012
This one from Astronomy Picture of the Day a few days ago really tickled me.
It’s a sundial but with an unusual (and unusually large) gnomon.
Located at the Ãcole Nationale Supérieure des Mines de Paris in Valbonne Sophia Antipolis in south-east France, twice each year its arrangement allows the sun’s rays to pick out the word solstice by shining through gaps in the metal struts. On two other days in the year it spells equinoxe.
