Packet 12: Bonus 15
This scientist’s “number” can both refer to the number of protons in the universe and the largest number X such that a cyclist has cycled at least X miles on at least X days. For 10 points each:
[10m] Coordinates named for David Finkelstein and what scientist remove the event horizon’s false singularity? He also names a value equal to 4 pi G M c over opacity, which is derived by setting gravity and radiation pressure equal.
ANSWER: Arthur Eddington [accept Eddington number or Eddington–Finkelstein coordinates or Eddington limit]
[10h] The ingoing and outgoing Eddington-Finkelstein coordinates v and u equal time plus or minus this coordinate. This coordinate denoted r-star approaches negative infinity as r approaches 2GM
ANSWER: the tortoise coordinate
[10e] One can use these mathematical constructs to show that the tortoise from Zeno’s paradox loses the race. The small-angle approximation that “sine x equals x” is derived by truncating an infinite one of these constructs.
ANSWER: power series [or infinite series; or convergent series; or geometric series; or Taylor series; or Maclaurin series]
