The Giants clinched their third straight victory with a 35-24 triumph over the New York Jets. The Giants scored 28 points in the decisive second half to overcome a 10-point deficit. Rookie CB Aaron Ross made his presence felt with a crucial interception off of QB Chad Pennington with the Jets driving and up three in the third then sealed the win with an interception return for a touchdown late in the fourth. The Jets got off to a fast start as returning running back Brandon Jacobs fumbled and the Jets' Kerry Rhodes returned it for a TD. The Giants responded with a 9-play, 67-yard drive ending in a touchdown run by Derrick Ward. However, the Giants defense, susceptible to third down conversions the first week of the season struggled again today and allowed the Jets to drive 93 yards late in the half for a 14-7 lead. The Jets were 3 for 3 on third down on the drive including some big catches by Laveranues Coles. Pennington hit Brad Smith for a 16-yard touchdown. After a bad interception from Eli Manning, the Jets added a field goal by Mike Nugent for a 17-7 halftime lead. The Giants fought back, going back to the ground game to start the second half. Plaxico Burress added a 25-yard completion from Manning and Jacobs pounded it in for a 19-yard touchdown. The Jets responded as Leon Washington ran 98 yards for a touchdown. Big Blue again fought back, driving 68 yards featuring a mix of runs and passes. Jeremy Shockey notched his first touchdown of the season with a 13-yard catch and run bringing the Giants within three after three quarters. The Jets responded with a drive of their own including several third down conversions but rookie Aaron Ross made the first of several big plays including a deep interception. The Giants drove 99 yards, which ended with a spectacular 53-yard touchdown catch and run by Plaxico Burress, who stiff-armed a Jet defender down the sideline. With the Jets driving for a score, Ross struck again, intercepting Pennington and returned it 43 yards to clinch the win. Brandon Jacobs notched his first ever 100-yard rushing performance, Manning managed 186 yards and 2 touchdowns despite a poor first half, Osi Umenyiora added a sack and Sam Madison added his first interception of the season. The Giants had now won four straight regular season meetings against the Jets and improved to 3-2 on the season.

In 212 BC, the Emperor Qin Shi Huang commanded all books in the Qin Empire other than officially sanctioned ones be burned. This decree was not universally obeyed, but as a consequence of this order little is known about ancient Chinese mathematics before this date. After the Burning of books and burying of scholars of 212 BC, the Han dynasty (202 BC–220 AD) produced works of mathematics which presumably expanded on works that are now lost. The most important of these is The Nine Chapters on the Mathematical Art, the full title of which appeared by AD 179, but existed in part under other titles beforehand. It consists of 246 word problems involving agriculture, business, employment of geometry to figure height spans and dimension ratios for Chinese pagoda towers, engineering, surveying, and includes material on right triangles. It created mathematical proof for the Pythagorean theorem, and a mathematical formula for Gaussian elimination. The treatise also provides values of π, which Chinese mathematicians originally approximated as 3 until Liu Xin (scholar) (d. 23 AD) provided a figure of 3.1457 and subsequently Zhang Heng (78-139) approximated pi as 3.1724, as well as 3.162 by taking the square root of 10. Liu Hui commented on the Nine Chapters in the 3rd century AD and Liu Huis π algorithm accurate to 5 decimal places (i.e. 3.14159). Though more of a matter of computational stamina than theoretical insight, in the 5th century AD Zu Chongzhi computed Milü to seven decimal places (i.e. 3.141592), which remained the most accurate value of π for almost the next 1000 years. He also established a method which would later be called Cavalieris principle to find the volume of a sphere.
