Caspar de Wilde

Caspar de Wilde (12 May 1618 or 12 May 1620 - 30 October 1677) was a renowned Brunanter theologian, mathematician and physicist, who taught at the Grijzestad University.

De Wilde investigated the free fall of objects, confirming that the distance of fall was proportional to the square of the time taken. De Wilde also made a calculation of the gravitational constant by recording the oscillations of an accurate pendulum.
