is my cal. correct?
SoL= 299,792,458m/s
1furlongs= 201.168m
201.168 / 299,792,448 = 6 x 10^-7 sec/furlongs

SoL= 1,079,252,848.8km/hour
1fortnight=14days
24h=1day
1,079,252,848.8 x 14 x 24 = 3.6 x 10^11 km/fortnight

Ok, so we have gone to the moon. Do you beleive that we will have success in colonizing the moon or mars?

theres this game. you pick a three digit number whose digits must be from 1-6 and then you roll 3 dice and if your digits are on the dice [any order cuz you roll them all at once] then you win some money. it costs a dollar to play this game and the question is to determine how much you win. fair payout so that you're expected to lose as much as you gain.
