On this day in 1789 William Herschel discovered the moon Mimas of Saturn with his 48 inch reflector. This moon is now seen to have one huge crater, much larger than all other craters of the moon, and this had been named 'Herschel'.

Quotation of the day
From Bernhard Riemann
Therefore, either the reality on which our space is based must form a discrete manifold or else the reason for the metric relationships must be sought for, externally, in the binding forces acting on it.
