Isaac Barrow Quotes
As a stick, when once it is dry and stiff you may break it, but you can never bend it into a straighter posture; so doth the man become incorrigible who is settled and stiffened into vice.

Isaac Barrow was an English Christian theologian and mathematician who is generally given credit for his early role in the development of infinitesimal calculus; in particular, for the discovery of the fundamental theorem of calculus. His work centered on the properties of the tangent; Barrow was the first to calculate the tangents of the kappa curve. He is also notable for being the inaugural holder of the prestigious Lucasian Professorship of Mathematics, a post later held by his student, Isaac Newton.
