Q: 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.
How many people changed the values of pi?

A: 2
P: In 1571 the Crimean Khan burned Moscow. He tried again the next year and was defeated. Another large raid failed in 1591. The raiding area may have moved slightly south and east. Attacks east of Ryazan are mentioned more frequently. After 1585 forts were built far to the south to block the Muravsky Trail, but these had no visible effect in this period. Raids on Poland are mentioned under 1577, 1584 and 1595.
Answer this: How many years after 1571 did another large raid fail?

A: 20
Problem: Coming off their bye week, the Cowboys went home for a Week 7 duel with the Atlanta Falcons.  Dallas would trail in the first quarter as Falcons quarterback Matt Ryan found wide receiver Roddy White on a 4-yard touchdown pass.  In the second quarter, the Cowboys came out shooting as kicker Nick Folk made a 38-yard field goal, followed by quarterback Tony Romo completing a 59-yard touchdown pass to wide receiver Miles Austin and a 5-yard touchdown pass to wide receiver Patrick Crayton. Atlanta tried to catch up in the third quarter with running back Michael Turner's 2-yard touchdown run, yet Dallas answered with Romo finding Austin again on a 22-yard touchdown pass.  The Cowboys would increase their lead in the fourth quarter with Folk nailing a 46-yard field goal and Crayton returning a punt 73 yards for a touchdown.  The Falcons tried to come back with Ryan's 30-yard touchdown pass to wide receiver Eric Weems, yet Dallas closed out the game with Folk's 34-yard field goal.

What are the top two longest touchdown passes made?
Answer: 59-yard
Q: With the 49ers offense continuing to struggle in the game, the defense more than made up for it. The 49ers defense intercepted Giants QB Eli Manning 5 times and sacked him twice. In the 4th quarter, with the 49ers holding a 16-10 lead, the Giants marched down the field to the 49ers 4 yard line with 5:25 left to play. The 49ers defense forced 3 incomplete passes and rookie linebacker Chris Borland intercepted Eli Manning's throw on 4th and goal to preserve the win. This was the second time this season the 49ers defense had a goal line stand late in a game (Week 4 vs Eagles). Colin Kaepernick went 15/29 for 193 yards and a touchdown pass. Frank Gore had 19 carries for 95 yards. With the win, the 49ers moved to 6-4 on the season.
Who was the 49ers leading rusher?
A: Frank Gore
