GeekDad Puzzle of the Week Answer: Bigger than Googol!

Bigger than Googol!:
Q: What is the first Fibonacci number bigger than a googol?
This was relatively easy in Haskell:

let fib = 0 : 1 : zipWith (+) fib (tail fib)
let answer = [ (n, fib!!n) | n <- [1..1000], (fib!!(n-1) <= 10^100) && (fib!!n > 10^100) ]
answer
(481,14913169640232740127827512057302148063648650711209401966150219926546779697987984279570098768737999681)

A: F(481) is the first Fibonacci number greater than googol. The numerical value is given above, but just for fun here's that number in words:
fourteen duotrigintillion, nine hundred thirteen untrigintillion, one hundred sixty-nine trigintillion, six hundred forty novemvigintillion, two hundred thirty-two octovigintillion, seven hundred forty septemvigintillion, one hundred twenty-seven sesvigintillion, eight hundred twenty-seven quinquavigintillion, five hundred twelve quattuorvigintillion, fifty-seven tresvigintillion, three hundred two duovigintillion, one hundred forty-eight unvigintillion, sixty-three vigintillion, six hundred forty-eight novemdecillion, six hundred fifty octodecillion, seven hundred eleven septendecillion, two hundred nine sexdecillion, four hundred one quindecillion, nine hundred sixty-six quattuordecillion, one hundred fifty tredecillion, two hundred nineteen duodecillion, nine hundred twenty-six undecillion, five hundred forty-six decillion, seven hundred seventy-nine nonillion, six hundred ninety-seven octillion, nine hundred eighty-seven septillion, nine hundred eighty-four sextillion, two hundred seventy-nine quintillion, five hundred seventy quadrillion, ninety-eight trillion, seven hundred sixty-eight billion, seven hundred thirty-seven million, nine hundred ninety-nine thousand, six hundred eighty-one

NPR Sunday Puzzle (Feb 19, 2012): Adjoining States Puzzle

NPR Sunday Puzzle (Feb 19, 2012): Adjoining States Puzzle:
Q: The word "marten," as in the animal, consists of the beginning letters of "Mississippi," "Arkansas," "Texas," and "New Mexico"; you can actually drive from Mississippi to Arkansas to Texas to New Mexico in that order. What is the longest common English word you can spell by taking the beginning letters of consecutive states in order as you travel through them? Puzzlemaster Will Shortz's answer has eight letters, but maybe you can top that.
I see a number of ways to match Will's answer but I'm still working on a way to top him.

Edit: The first word I found was millions, hence the clue above about "a number"
A: Assuming we can't visit a state more than once and we can't cross the four-corners diagonally, I have these words:

Common words:
omissions = oklahoma, missouri, iowa, nebraska, south dakota
ketamines = kentucky, tennessee, arkansas, missouri, nebraska, south dakota
millions = missouri, illinois, iowa, nebraska, south dakota
missions = missouri, iowa, nebraska, south dakota
misstate = missouri, tennessee, arkansas, texas
vitamins = virginia, tennessee, arkansas, missouri, nebraska, south dakota

Less common words:
illimitate = illinois, missouri, tennessee, arkansas, texas
artemisin = arkansas, tennessee, missouri, iowa, nebraska
coregnant = california, oregon, nevada, arizona, new mexico, texas
coregonid = california, oregon, idaho
florigens = florida, georgia, north carolina, south carolina
miltomate = mississippi, louisiana, texas, oklahoma, missouri, arkansas, tennessee
nevermass = new hampshire, vermont, massachusetts
virgining = virginia, north carolina, georgia
floriage = florida, alabama, georgia
floriate = florida, alabama, tennessee
misagent = mississippi, alabama, georgia, north carolina, tennessee
misatone = missouri, arkansas, texas, oklahoma, new mexico

Finally if you are going to allow repeated visits to the same state, I have:
non-omissions = new mexico, oklahoma, new mexico, oklahoma, missouri, iowa, nebraska, south dakota
concomitate = colorado, nebraska, colorado, oklahoma, missouri, tennessee, arkansas, texas
amalgamate = arkansas, mississippi, alabama, georgia, alabama, mississippi, arkansas, tennessee
amalgamist = arkansas, mississippi, alabama, georgia, alabama, mississippi, tennessee
mononomial = missouri, oklahoma, new mexico, oklahoma, new mexico, oklahoma, missouri, arkansas, louisiana
... and quite a few shorter words

By the way, I'm with you - cool puzzle!

Edit: The title of the puzzle was poking fun at Will and whether or not Santa Claus is real. The other hints were By the Way and I'm With You which are albums by the Red Hot Chili Peppers and the word cool which could be a synonym for chilly.
A: Sant(a) + Iago = Santiago (Chile)

NPR Sunday Puzzle (Feb 5, 2012): A Stern Elk and a Rattlesnake?

NPR Sunday Puzzle (Feb 5, 2012): A Stern Elk and a Rattlesnake?:
Q: Name an animal. Add the letters "A" and "T," and rearrange the result to name another animal. These are both animals that might be found in a zoo, and the last letter of the first animal is the first letter of the last one.
I was surprised to find the second animal has a longer lifespan than the first and will often weigh more.

Edit: Gorillas have a lifespan of 35 to 40 years while American alligators will live to 50+ in the wild. An adult male gorilla weighs around 400 lbs. while an adult American alligator will weigh around 800 lbs.
A: GORILLA + AT --> ALLIGATOR

NPR Sunday Puzzle (Jan 29, 2012): An Equation for 2012

NPR Sunday Puzzle (Jan 29, 2012): An Equation for 2012:
Q: Write the digits from 1 to 9 in a line. If you put a plus sign after the 2, a times sign after the 4, and plus signs after the 6 and 8, the line shows 12 + 34 x 56 + 78 + 9, which equals 2003. That's nine years off from our current year 2012. This example uses four arithmetic symbols. The object is to use just three of the following arithmetic operations: addition, subtraction, multiplication and division, in a line from 1 to 9 to get 2012 exactly. The operations should be performed in order from left to right. There are no tricks to this puzzle. Can you do it?
I was just about to retire for the evening, but I figured you might need some assistance in solving the puzzle, so your help is... Gee, how do I give you a hint to a math puzzle?

Edit: The hints were "retire" (Social Security Administration = SSA = subtract, subtract, add) and "assistance" and "help" (411 = number of digits to group together, with 3 being assumed for the remaining digits).
A: 1234 - 5 - 6 + 789 = 2012
