Barrow is an old lunarcrater that is located near the northern limb of the Moon. It lies between Goldschmidt crater to the northwest and the irregular Meton crater formation to the northeast. To the southwest is the W. Bond crater remnant.
The outer wall of Barrow crater has been heavily eroded by subsequent impacts, and reshaped by intruding craters. As a result the rim now resembles a ring of rounded hills and peaks surrounding the flat interior. The younger satellite crater 'Barrow A' lies across the southwest rim. At the eastern end of the crater is a narrow gap in the rim that joins the floor to the adjacent Meton crater. The rim achieves its maximum height and extend in the northwest, where it is joined to Goldschmidt crater.
The interior of Barrow crater has been resurfaced by lava flows, leaving a flat surface that is marked by many tiny craterlets. Faint traces of ray material from the Anaxagoras crater to the west forms streaks across the floor of Barrow.
Satellite craters
By convention these features are identified on Lunar maps by placing the letter on the side of the crater mid-point that is closest to Barrow crater.
Barrow studied arithmetic, geometry and optics and, like all students of the time, was encouraged not to specialise in a subject such as mathematics before graduating.
Barrow had taken an oath to study divinity when he was admitted as a fellow, and, after briefly studying medicine, he began studying divinity again.
Barrow was an obvious choice for this position and he relinquished the Greek chair for the mathematics because, he explained, of his greater interest in mathematics than Greek, because less work was involved, and that it had always been his intention to hold the Greek chair temporarily.
Isaac Barrow (1630 - May 4, 1677) was an English divine, scholar and mathematician who is generally given minor credit for his role in the development of modern calculus; in particular, for his work regarding the tangent; for example, Barrow is given credit for being the first to calculate the tangents of the kappa curve.
Barrow's character as a man was in all respects worthy of his great talents, though he had a strong vein of eccentricity.
Barrow also worked out a few of the easier properties of thin lenses, and considerably simplified the Cartesian explanation of the rainbow.
