"Where there is matter, there is geometry."
— Johannes Kepler
Where There Is Matter There Is
Where there is matter, there is geometry.
About this quote
Johannes Kepler wrote this in De Fundamentis Astrologiae Certioribus (1602), a work that attempted to place astrology on a more rigorous scientific footing by linking celestial geometry to terrestrial effects. The statement anticipated the later development of mathematical physics, in which the structure of space itself is described geometrically — a vision Isaac Newton would formalize and Albert Einstein would ultimately transform.
